    To get started with this blank TiddlyWiki, you'll need to modify the following tiddlers:
    * SiteTitle & SiteSubtitle: The title and subtitle of the site, as shown above (after saving, they will also appear in the browser title bar)
    * MainMenu: The menu (usually on the left)
    * DefaultTiddlers: Contains the names of the tiddlers that you want to appear when the TiddlyWiki is opened
    You'll also need to enter your username for signing your edits: <<option txtUserName>>

    These InterfaceOptions for customising TiddlyWiki are saved in your browser

    Your username for signing your edits. Write it as a WikiWord (eg JoeBloggs)

    <<option txtUserName>>
    <<option chkSaveBackups>> SaveBackups
    <<option chkAutoSave>> AutoSave
    <<option chkRegExpSearch>> RegExpSearch
    <<option chkCaseSensitiveSearch>> CaseSensitiveSearch
    <<option chkAnimate>> EnableAnimations

    Also see AdvancedOptions

    A task has a description, an estimate of how long it will take, and a record of how much time you have spent on it so far.  Here's an example, which shows a task estimated at 3 hours, with 1 hour spent on it, and ''2'' hours remaining:
    <<<
    <<task 3 3 1>> Add a double-click handler to the description cell that opens the editor and selects the text
    <<<
    If you hover the mouse over any part of the task -- the bullet, the description, or any of the numeric cells -- a tip will appear explaining it.

    Try modifying the time spent.  Suppose you've just spent one more hour and want to record it.  Just click on the second yellow cell, and enter "+1" (sans the quote marks, of course) in the popup window.  Watch the time remaining go down to 1 hour.

    In reality, I originally estimated this task at a half-hour, but it ended up taking 3.5 hours.  The macro also tracks your original estimate, if it is different from the current estimate, in a fourth cell like this:
    <<<
    <<task 0.5 2 1>> Add a double-click handler to the description cell that opens the editor and selects the text
    <<<
    You can adjust the current estimate in the same way as you adjusted the time spent.  Click on the current estimate cell (the first yellow cell), and change it to 2.5 hours by typing "2.5" or "+.5".

    You can also adjust the time remaining, which will modify either the estimate (if the time remaining increases) or the time spent (if it decreases).  Click on the time remaining and add an hour by typing "+1".

    When the time remaining goes to zero, the task is considered complete:
    <<<
    <<task 0.5 3.5 3.5>> Add a double-click handler to the description cell that opens the editor and selects the text
    <<<
    If you haven't already done so, try double-clicking the description.  Yes, it really does open up the editor and select just the text of the description.

    ----
    To continue, click the down-arrow and choose another section: <<tag TaskMacroTutorial>>

    A task's description is a single wikified line, so it can contain any formatting that can be specified on one line:

    You can specify just the description of a task, and leave it unestimated.  Click the question mark to enter the estimate:
    <<<
    <<task>> Beef up the time click handlers to allow entry of ''two'' values each: cur&spent, spent&rem. Add click handler to done tasks' spent cells too, to reopen them (like with +0, 1).
    <<<
    As this task implies, you can enter two values in the popup when you click on any of the time cells.  Separate them with spaces and/or a comma.  Experiment:
    <<<
    <<task 1>> Beef up the time click handlers to allow entry of ''two'' values each: cur&spent, spent&rem. Add click handler to done tasks' spent cells too, to reopen them (like with +0, 1).
    <<<
    Finally, if you haven't already figured this out, you can double-click on a task's bullet to mark it complete, with the current estimate entered as the time spent.

    If you've been paying attention, you've noticed that I haven't discussed the actual adding of calls to the task macro within your tiddlers -- it's all been about modifying tasks that were already there.  That's because adding tasks via the taskadder macro is much easier and more intuitive than adding them by hand.

    And setting up a taskadder is simplicity itself.  Just add {{{<<taskadder>>}}} to your tiddler.  You will see this:
    <<<
    <<taskadder>>
    <<<
    Just type a task description into the first field, and your initial estimate for how long it will take into the second field.  Click the "add task" button, or just hit Enter in either of the fields, to add the new task into the tiddler.  Notice that you can just start typing a new task as soon as you're done entering the first one.

    You can have as many taskadders as you like in any tiddler.  The last one you used will capture the keyboard focus when it is redisplayed, meaning you can type a series of tasks without using the mouse.  Try adding some tasks here and in the above adder:
    <<<
    <<taskadder>>
    <<<
    Notice that the one you just used takes focus when this tiddler is redisplayed.

    A taskadder by default adds tasks above itself.  You can make it add them below by adding a {{{below}}} argument to the macro call:
    <<<
    <<taskadder below>>
    <<<

    In this tutorial, we've been looking mostly at individual tasks.  In real life, though, you'll typically have a series of them, or even several series of them in the same tiddler.  In these cases you want a summary that tells you -- at a minimum -- how much time you still expect to spend on these tasks.

    To get such a summary, just add {{{<<tasksum start>>}}} before the tasks and {{{<<tasksum end>>}}} after them.  Here's an example:
    <<<
    <<tasksum start>>
    <<task 0.25 0.25 0.25>> Add tooltips to the various cells
    <<task 1 0.75 0.75>> Figure out how to add auto-updating click handlers to the time cells
    <<task 2 2 0>> Add simple click handlers to cur, spent, rem: just allow direct setting of values
    <<task 1 3.5 2.5>> Add a double-click handler to the desc cell that opens the editor and selects the text
    <<task 1 1 0>> Beef up the time click handlers to allow entry of two values each: cur&spent, spent&rem. Add click handler to done tasks' spent cells too, to reopen them (like with +0, 1).
    <<task 1 1 0>> Beef up the time click handlers to handle leading + or -
    <<task 1 1 0>> Add a double-click handler to the status cell that functions like typing 0 into the rem cell
    <<tasksum end>>
    <<<
    If you'd rather have the summary at the top, just add {{{here}}} to the start call, ie {{{<<tasksum start here>>}}}.
    <<<
    <<tasksum start here>>
    <<task 0.25 0.25 0.25>> Add tooltips to the various cells
    <<task 1 0.75 0.75>> Figure out how to add auto-updating click handlers to the time cells
    <<task 2 2 0>> Add simple click handlers to cur, spent, rem: just allow direct setting of values
    <<tasksum end>>
    <<<
    You can nest these things if you like, just be sure to match starts and ends:
    <<<
    <<tasksum start here>>
    * Time cell manipulation:<<tasksum start>>
    <<task 1 0.75 0.75>> Figure out how to add auto-updating click handlers to the time cells
    <<task 2 2 0>> Add simple click handlers to cur, spent, rem: just allow direct setting of values
    <<task 1 1 0>> Beef up the time click handlers to allow entry of two values each: cur&spent, spent&rem. Add click handler to done tasks' spent cells too, to reopen them (like with +0, 1).
    <<task 1 1 0>> Beef up the time click handlers to handle leading + or -
    <<tasksum end "Cell manipulation:">>
    <<br>>
    * Double-click handling:<<tasksum start>>
    <<task 1 3.5 2.5>> Add a double-click handler to the desc cell that opens the editor and selects the text
    <<task 1 1 0>> Add a double-click handler to the status cell that functions like typing 0 into the rem cell
    <<tasksum end "Double-clicks:">>

    <<tasksum end>>
    <<<
    Finally, the simplest way to use tasksum is to add it to your view template.  See TaskSummaryViewTemplate for an example template.  Note that if no tasks are present between the start and end, nothing is displayed.

    The TaskMacroPlugin can be installed like any other TiddlyWiki plugin, and used without further effort.  However, there are two issues that may affect you.  (To get started with a brand new wiki that does not have these issues, consider downloading the [[empty LabWiki|empty_labwiki.html]].)
    # The task macros don't play nicely with the default TiddlyWiki display of tags.  In the default view template, a tiddler's list of tags is shown in a little box that floats in the upper right corner of the tiddler.  However, this little box may interfere with the tables used by the task macros.  In Firefox, the tables are drawn right over the top of the tag box, rendering both of them illegible.  In Internet Explorer, the tag box forces the tables to be pushed down below the box, which can waste a lot of space.<<br>><<br>>Thus, I recommend changing your view template to eliminate the little box.  If you use Simon Baird's [[TagglyTagging|http://simonbaird.com/mptw/#TagglyTagging]] (as LabWiki does), then my TaskSummaryViewTemplate might be a good alternative.  Simply import it into your wiki and rename it to ViewTemplate.  This template also demonstrates how to incorporate the tasksum macro into every tiddler so any tiddler with tasks has a summary at the top.<<br>><<br>>
    # Most view templates also add a minus sign ("-") before the "close" command.  TiddlyWiki interprets this to mean that you want the close command to be executed if you hit the Escape key from within the tiddler.<<br>><<br>>However, most tiddlers never have focus, and so never give you the opportunity to try it out.  But if you have a taskadder in your tiddler, then you suddenly enable this feature -- and you probably don't want it.  It means that if you type a nice long task description and then hit Escape, that description will be lost and the tiddler will be closed.  So I recommend that you remove the minus sign from the view template's menu altogether, as I have done in LabWiki's own ViewTemplate.

    |Name|BetterTimelineMacro|
    |Created by|SaqImtiaz|
    |Location|http://tw.lewcid.org/#BetterTimelineMacro|
    |Version|0.5 beta|
    |Requires|~TW2.x|
    !!!Description:
    A replacement for the core timeline macro that offers more features:
    *list tiddlers with only specfic tag
    *exclude tiddlers with a particular tag
    *limit entries to any number of days, for example one week
    *specify a start date for the timeline, only tiddlers after that date will be listed.

    !!!Installation:
    Copy the contents of this tiddler to your TW, tag with systemConfig, save and reload your TW.
    Edit the ViewTemplate to add the fullscreen command to the toolbar.

    !!!Syntax:
    {{{<<timeline better:true>>}}}
    ''the param better:true enables the advanced features, without it you will get the old timeline behaviour.''

    additonal params:
    (use only the ones you want)
    {{{<<timeline better:true  onlyTag:Tag1 excludeTag:Tag2 sortBy:modified/created firstDay:YYYYMMDD maxDays:7 maxEntries:30>>}}}

    ''explanation of syntax:''
    onlyTag: only tiddlers with this tag will be listed. Default is to list all tiddlers.
    excludeTag: tiddlers with this tag will not be listed.
    sortBy: sort tiddlers by date modified or date created. Possible values are modified or created.
    firstDay: useful for starting timeline from a specific date. Example: 20060701 for 1st of July, 2006
    maxDays: limits timeline to include only tiddlers from the specified number of days. If you use a value of 7 for example, only tiddlers from the last 7 days will be listed.
    maxEntries: limit the total number of entries in the timeline.

    This just starts as braindump, I will refine it soon:
    * handle all files Lumiera uses at runtime (media, edl, temp data)
    * manage filehandles, Lumiera might use more more files than available filehandles
    * manage temporary data
    * do caching
    * io will be blocked where the backend tells the core where it can expect the data (not read()/write() like)
    * kind-of garbage collector
    * do prefetching
    * no/low latency for the core the prefetcher and other things ensure that data is available in time
    * translate any input into a format which the Lumiera core understands (demux, decode)
    * same for encoding to output formats
    * offer a plugin API for encoders/decoders
    * maybe network backend for serving data to distributed render nodes
    * can do some load control or management (trigger adaptive rendering if system is idle etc)
    * pull based arch
    * Serialize persistent data (Project / EDL's)

    Look at [[Overview]] for the current design proposal

    DataBackend

    [[File]] associates a filename with the underlying FileDescriptor. This allows [[File]]s which have serveral names (hardlinks) to share a underlying backend.

    'FileDescriptor' is the superclass of all possible filetypes, it has a weak reference to a FileHandle which is managed in FilehandleCache, on creation only the existence (when reading) or access for write for new files are checked. 'FileDescriptor' stores some generic metadata about the underlying file and intended use. But actual opening is done on demand.

    The content is memory mapped into the process address space, this is managed by FileMap objects and a FileMapCache.

    'FileHandle's are managed by the FileHandleCache, they are just storing the underlying OS file handles and managed in a lazy/weak way, (re)opened when needed and aging in the cache when not needed, since the amount of open file handles is limited aged ones will be closed and reused when the system needs to open another file.

    Each 'FileMap' object contains many [[Frame]]s. The actual layout depends on the type of the [[File]]. Mappings need to be page aligned while [[Frame]]s can be anywhere within a file and dynamically sized.

    All established [[FileMap]]s are managed in a FileMapCache. This is similar to the FileHandleCache, but mappings which are in use are checked out of the aging list and thus become locked from aging/purging.

    FileMap objects are transparent to the application. It will only requests [[Frame]]s as in position and size (and some other parameters).

    The 'FileMapCache' keeps a list of FileMaps which are currently not in use and subject of aging.
    Whenever a FileMap is in use, it is checked out into an in-use list where it is not subject to aging.

    'FilehandleCache' storing a finite maximum number of [[FileHandle]]s as a list. As long the configured maximum of open files is not reached new file handles are stored at the begin of the list. Whenever a filehandle is accessed it is moved to the begin of the list too. Unused filehandles propagate towards the end of the list. When the maximum of open filehandles is reached, aged filehandles are closed and taken from the end.

    'Frames' are the smallest datablocks handled by the Backend. The application tells the Backend to make [[File]]s available and then only requests Frames from the Backend. All other datastructures of the backend are private.

    Actually Frames are (references to) blocks of continuous memory. They can be anything depending on the usage of the [[File]] (Video frames, encoder frames, blocks of sound samples).

    Each [[Frame]] points to a [[FrameDescriptor]] which describes the shared properties of [[Frame]]s of the same kind. For video frames this [[FrameDescriptor]] will define the policies of the used color model, resolution, aspect ratio and so on, for example.

    Frames are referenced by a smart-pointer like object which manages the lifetime and caching behavior. There are 3 states such a frame reference can be in:
    # readonly: the backing FileMap is checked out from the aging list, frames can be read
    # readwrite: the backing FileMap is checked out from the aging list, frames can be read and written (depends on the filemode as well)
    # weak: the FileMap object is checked back into the aging list, the frame can't be accessed but we can try to transform a weak reference into a readonly or readwrite reference

    Frames can be addressed uniquely (needs to be worked out) whenever a frame is not available. The backend can initiate a (probably recursive) render for it.

    Accessing [[Frame]]s may add further renderjobs for related frames to the [[Prefetch]] task.

    ''InlineJavascriptPlugin for ~TiddlyWiki version 1.2.x and 2.0''
    ^^author: Eric Shulman - ELS Design Studios
    source: http://www.TiddlyTools.com/#InlineJavascriptPlugin
    license: [[Creative Commons Attribution-ShareAlike 2.5 License|http://creativecommons.org/licenses/by-sa/2.5/]]^^

    Insert Javascript executable code directly into your tiddler content. Lets you ''call directly into TW core utility routines, define new functions, calculate values, add dynamically-generated TiddlyWiki-formatted output'' into tiddler content, or perform any other programmatic actions each time the tiddler is rendered.
    !!!!!Usage
    <<<
    When installed, this plugin adds new wiki syntax for surrounding tiddler content with {{{<script>}}} and {{{</script>}}} markers, so that it can be treated as embedded javascript and executed each time the tiddler is rendered.

    ''Deferred execution from an 'onClick' link''
    By including a label="..." parameter in the initial {{{<script>}}} marker, the plugin will create a link to an 'onclick' script that will only be executed when that specific link is clicked, rather than running the script each time the tiddler is rendered.

    ''External script source files:''
    You can also load javascript from an external source URL, by including a src="..." parameter in the initial {{{<script>}}} marker (e.g., {{{<script src="demo.js"></script>}}}). This is particularly useful when incorporating third-party javascript libraries for use in custom extensions and plugins. The 'foreign' javascript code remains isolated in a separate file that can be easily replaced whenever an updated library file becomes available.

    ''Defining javascript functions and libraries:''
    Although the external javascript file is loaded while the tiddler content is being rendered, any functions it defines will not be available for use until //after// the rendering has been completed. Thus, you cannot load a library and //immediately// use it's functions within the same tiddler. However, once that tiddler has been loaded, the library functions can be freely used in any tiddler (even the one in which it was initially loaded).

    To ensure that your javascript functions are always available when needed, you should load the libraries from a tiddler that will be rendered as soon as your TiddlyWiki document is opened. For example, you could put your {{{<script src="..."></script>}}} syntax into a tiddler called LoadScripts, and then add {{{<<tiddler LoadScripts>>}}} in your MainMenu tiddler.

    Since the MainMenu is always rendered immediately upon opening your document, the library will always be loaded before any other tiddlers that rely upon the functions it defines. Loading an external javascript library does not produce any direct output in the tiddler, so these definitions should have no impact on the appearance of your MainMenu.

    ''Creating dynamic tiddler content''
    An important difference between this implementation of embedded scripting and conventional embedded javascript techniques for web pages is the method used to produce output that is dynamically inserted into the document:
    * In a typical web document, you use the document.write() function to output text sequences (often containing HTML tags) that are then rendered when the entire document is first loaded into the browser window.
    * However, in a ~TiddlyWiki document, tiddlers (and other DOM elements) are created, deleted, and rendered "on-the-fly", so writing directly to the global 'document' object does not produce the results you want (i.e., replacing the embedded script within the tiddler content), and completely replaces the entire ~TiddlyWiki document in your browser window.
    * To allow these scripts to work unmodified, the plugin automatically converts all occurences of document.write() so that the output is inserted into the tiddler content instead of replacing the entire ~TiddlyWiki document.

    If your script does not use document.write() to create dynamically embedded content within a tiddler, your javascript can, as an alternative, explicitly return a text value that the plugin can then pass through the wikify() rendering engine to insert into the tiddler display. For example, using {{{return "thistext"}}} will produce the same output as {{{document.write("thistext")}}}.

    //Note: your script code is automatically 'wrapped' inside a function, {{{_out()}}}, so that any return value you provide can be correctly handled by the plugin and inserted into the tiddler. To avoid unpredictable results (and possibly fatal execution errors), this function should never be redefined or called from ''within'' your script code.//

    ''Accessing the ~TiddlyWiki DOM''
    The plugin provides one pre-defined variable, 'place', that is passed in to your javascript code so that it can have direct access to the containing DOM element into which the tiddler output is currently being rendered.

    Access to this DOM element allows you to create scripts that can:
    * vary their actions based upon the specific location in which they are embedded
    * access 'tiddler-relative' information (use findContainingTiddler(place))
    * perform direct DOM manipulations (when returning wikified text is not enough)

    Insert Javascript executable code directly into your tiddler content. Lets you ''call directly into TW core utility routines, define new functions, calculate values, add dynamically-generated TiddlyWiki-formatted output'' into tiddler content, or perform any other programmatic actions each time the tiddler is rendered.
    !!!!!Usage
    <<<
    When installed, this plugin adds new wiki syntax for surrounding tiddler content with {{{<script>}}} and {{{</script>}}} markers, so that it can be treated as embedded javascript and executed each time the tiddler is rendered.

    ''Deferred execution from an 'onClick' link''
    By including a label="..." parameter in the initial {{{<script>}}} marker, the plugin will create a link to an 'onclick' script that will only be executed when that specific link is clicked, rather than running the script each time the tiddler is rendered.

    ''External script source files:''
    You can also load javascript from an external source URL, by including a src="..." parameter in the initial {{{<script>}}} marker (e.g., {{{<script src="demo.js"></script>}}}). This is particularly useful when incorporating third-party javascript libraries for use in custom extensions and plugins. The 'foreign' javascript code remains isolated in a separate file that can be easily replaced whenever an updated library file becomes available.

    ''Display script source in tiddler output''
    By including the keyword parameter "show", in the initial {{{<script>}}} marker, the plugin will include the script source code in the output that it displays in the tiddler.

    ''Defining javascript functions and libraries:''
    Although the external javascript file is loaded while the tiddler content is being rendered, any functions it defines will not be available for use until //after// the rendering has been completed. Thus, you cannot load a library and //immediately// use it's functions within the same tiddler. However, once that tiddler has been loaded, the library functions can be freely used in any tiddler (even the one in which it was initially loaded).

    To ensure that your javascript functions are always available when needed, you should load the libraries from a tiddler that will be rendered as soon as your TiddlyWiki document is opened. For example, you could put your {{{<script src="..."></script>}}} syntax into a tiddler called LoadScripts, and then add {{{<<tiddler LoadScripts>>}}} in your MainMenu tiddler.

    Since the MainMenu is always rendered immediately upon opening your document, the library will always be loaded before any other tiddlers that rely upon the functions it defines. Loading an external javascript library does not produce any direct output in the tiddler, so these definitions should have no impact on the appearance of your MainMenu.

    ''Creating dynamic tiddler content''
    An important difference between this implementation of embedded scripting and conventional embedded javascript techniques for web pages is the method used to produce output that is dynamically inserted into the document:
    * In a typical web document, you use the document.write() function to output text sequences (often containing HTML tags) that are then rendered when the entire document is first loaded into the browser window.
    * However, in a ~TiddlyWiki document, tiddlers (and other DOM elements) are created, deleted, and rendered "on-the-fly", so writing directly to the global 'document' object does not produce the results you want (i.e., replacing the embedded script within the tiddler content), and completely replaces the entire ~TiddlyWiki document in your browser window.
    * To allow these scripts to work unmodified, the plugin automatically converts all occurences of document.write() so that the output is inserted into the tiddler content instead of replacing the entire ~TiddlyWiki document.

    If your script does not use document.write() to create dynamically embedded content within a tiddler, your javascript can, as an alternative, explicitly return a text value that the plugin can then pass through the wikify() rendering engine to insert into the tiddler display. For example, using {{{return "thistext"}}} will produce the same output as {{{document.write("thistext")}}}.

    //Note: your script code is automatically 'wrapped' inside a function, {{{_out()}}}, so that any return value you provide can be correctly handled by the plugin and inserted into the tiddler. To avoid unpredictable results (and possibly fatal execution errors), this function should never be redefined or called from ''within'' your script code.//

    ''Accessing the ~TiddlyWiki DOM''
    The plugin provides one pre-defined variable, 'place', that is passed in to your javascript code so that it can have direct access to the containing DOM element into which the tiddler output is currently being rendered.

    Access to this DOM element allows you to create scripts that can:
    * vary their actions based upon the specific location in which they are embedded
    * access 'tiddler-relative' information (use findContainingTiddler(place))
    * perform direct DOM manipulations (when returning wikified text is not enough)

    how is FileMetadata kept

    copying semantics of smart pointers

    explain opening/closing files (use() forget()?)

    difference between actual files and temporary. does it make sense to have temporary storage on diffent speed disks?

    statistics hit/fail max/min/avg timings, hard / soft fails, timing constraints, when is rerendering cheaper than caching?..

    adaptive rendering

    background rendering

    renderfarm

    [[FrameDescriptor]]s and [[Frame]] details, Policies composing frames

    Storage and logging of EDL's, unlimited undo, database,...

    When to Cache and when not to cache, aka instant [[Frame]] reuse

    Whenever Lumiera needs to access data this is done through the DataBackend described here.

    There are two main kinds how data is handled:
    * Project Description and EDL's are handled in a InMemoryDatabase which uses a [[Serializer]] for storing and logging modifications.
    * Media (audio, video, ...) is mapped as described below.

    The backend uses memory mapping to make data available to the program. This is little different to more common open/read/write/close file access while giving superior performance and much better memory utilization.

    The data backend must be capable to handle more data than will fit into the memory or even address space on 32 bit architectures.  Moreover a project may access more files than the OS can handle at a time, thus the for [[File]]s used by the Backend it needs a FilehandleCache to manage filehandles dynamically.

    Which parts of a File are actually mapped to physical RAM is managed by the kernel, it keeps a FileMapCache to manage the [[FileMap]]s we've set up.

    The application itself only requests [[Frame]]s from the backend.

    To minimize latency and optimize CPU utilization we have a [[Prefetch]] thread which operates a [[Scheduler]] to render and cache frames which are expected to be consumed soon. This prefetcher keeps [[Statistics]] for optimizing performance.

    With the {{{<part aPartName> ... </part>}}} feature you can structure your tiddler text into separate (named) parts.
    Each part can be referenced as a "normal" tiddler, using the "//tiddlerName//''/''//partName//" syntax (e.g. "About/Features"). E.g. you may create links to the parts, use it in {{{<<tiddler...>>}}} or {{{<<tabs...>>}}} macros etc.

    ''Syntax:''
    |>|''<part'' //partName// [''hidden''] ''>'' //any tiddler content// ''</part>''|
    |//partName//|The name of the part. You may reference a part tiddler with the combined tiddler name "//nameOfContainerTidder//''/''//partName//.|
    |''hidden''|When defined the content of the part is not displayed in the container tiddler. But when the part is explicitly referenced (e.g. in a {{{<<tiddler...>>}}} macro or in a link) the part's content is displayed.|
    |<html><i>any&nbsp;tiddler&nbsp;content</i></html>|<html>The content of the part.<br>A part can have any content that a "normal" tiddler may have, e.g. you may use all the formattings and macros defined.</html>|

    !Applications<html><a name="Applications"/></html>
    !!Refering to Paragraphs of a Longer Tiddler<html><a name="LongTiddler"/></html>
    Assume you have written a long description in a tiddler and now you want to refer to the content of a certain paragraph in that tiddler (e.g. some definition.) Just wrap the text with a ''part'' block, give it a nice name, create a "pretty link" (like {{{[[Discussion Groups|Introduction/DiscussionGroups]]}}}) and you are done.

    Notice this complements the approach to first writing a lot of small tiddlers and combine these tiddlers to one larger tiddler in a second step (e.g. using the {{{<<tiddler...>>}}} macro). Using the ''part'' feature you can first write a "classic" (longer) text that can be read "from top to bottom" and later "reuse" parts of this text for some more "non-linear" reading.

    <html><sub><a href="javascript:;" onclick="window.scrollAnchorVisible('Top',null, event)">[Top]</sub></a></html>

    !!Citation Index<html><a name="Citation"/></html>
    Create a tiddler "Citations" that contains your "citations".
    Wrap every citation with a part and a proper name.

    !!Creating "multi-line" Table Cells<html><a name="TableCells"/></html>
    You may have noticed that it is hard to create table cells with "multi-line" content. E.g. if you want to create a bullet list inside a table cell you cannot just write the bullet list
    {{{
    * Item 1
    * Item 2
    * Item 3
    }}}
    into a table cell (i.e. between the | ... | bars) because every bullet item must start in a new line but all cells of a table row must be in one line.

    Using the ''part'' feature this problem can be solved. Just create a hidden part that contains the cells content and use a {{{<<tiddler >>}}} macro to include its content in the table's cell.

    ''Example''
    {{{
    |!Subject|!Items|
    |subject1|<<tiddler ./Cell1>>|
    |subject2|<<tiddler ./Cell2>>|

    <part Cell1 hidden>
    * Item 1
    * Item 2
    * Item 3
    </part>
    ...
    }}}

    Notice that inside the {{{<<tiddler ...>>}}} macro you may refer to the "current tiddler" using the ".".

    BTW: The same approach can be used to create bullet lists with items that contain more than one line.

    <html><sub><a href="javascript:;" onclick="window.scrollAnchorVisible('Top',null, event)">[Top]</sub></a></html>

    !!Creating Tabs<html><a name="Tabs"/></html>
    The build-in {{{<<tabs ...>>}}} macro requires that you defined an additional tiddler for every tab it displays. When you want to have "nested" tabs you need to define a tiddler for the "main tab" and one for every tab it contains. I.e. the definition of a set of tabs that is visually displayed at one place is distributed across multiple tiddlers.

    With the ''part'' feature you can put the complete definition in one tiddler, making it easier to keep an overview and maintain the tab sets.

    ''Example''
    The standard tabs at the sidebar are defined by the following eight tiddlers:
    * SideBarTabs
    * TabAll
    * TabMore
    * TabMoreMissing
    * TabMoreOrphans
    * TabMoreShadowed
    * TabTags
    * TabTimeline

    Instead of these eight tiddlers one could define the following SideBarTabs tiddler that uses the ''part'' feature:
    {{{
    <<tabs txtMainTab
     Timeline Timeline SideBarTabs/Timeline
     All 'All tiddlers' SideBarTabs/All
     Tags 'All tags' SideBarTabs/Tags
     More 'More lists' SideBarTabs/More>>
    <part Timeline hidden><<timeline>></part>
    <part All hidden><<list all>></part>
    <part Tags hidden><<allTags>></part>
    <part More hidden><<tabs txtMoreTab
     Missing 'Missing tiddlers' SideBarTabs/Missing
     Orphans 'Orphaned tiddlers' SideBarTabs/Orphans
     Shadowed 'Shadowed tiddlers' SideBarTabs/Shadowed>></part>
    <part Missing hidden><<list missing>></part>
    <part Orphans hidden><<list orphans>></part>
    <part Shadowed hidden><<list shadowed>></part>
    }}}

    Notice that you can easily "overwrite" individual parts in separate tiddlers that have the full name of the part.

    E.g. if you don't like the classic timeline tab but only want to see the 100 most recent tiddlers you could create a tiddler "~SideBarTabs/Timeline" with the following content:
    {{{
    <<forEachTiddler
     sortBy 'tiddler.modified' descending
     write '(index < 100) ? "* [["+tiddler.title+"]]\n":""'>>
    }}}
    <html><sub><a href="javascript:;" onclick="window.scrollAnchorVisible('Top',null, event)">[Top]</sub></a></html>

    !!Using Sliders<html><a name="Sliders"/></html>
    Very similar to the build-in {{{<<tabs ...>>}}} macro (see above) the {{{<<slider ...>>}}} macro requires that you defined an additional tiddler that holds the content "to be slid". You can avoid creating this extra tiddler by using the ''part'' feature

    ''Example''
    In a tiddler "About" we may use the slider to show some details that are documented in the tiddler's "Details" part.
    {{{
    ...
    <<slider chkAboutDetails About/Details details "Click here to see more details">>
    <part Details hidden>
    To give you a better overview ...
    </part>
    ...
    }}}

    Notice that putting the content of the slider into the slider's tiddler also has an extra benefit: When you decide you need to edit the content of the slider you can just doubleclick the content, the tiddler opens for editing and you can directly start editing the content (in the part section). In the "old" approach you would doubleclick the tiddler, see that the slider is using tiddler X, have to look for the tiddler X and can finally open it for editing. So using the ''part'' approach results in a much short workflow.

    ***/

    There are 2 important points when we want to access data with low latency:
    # Since we handle much more data than it will fit into most computers RAM. The data which is backed in files has to be paged in and available when needed. The [[Prefetch]] Thread manages page hinting to the kernel (posix_madvise()..)
    # Intermediate [[Frame]]s must eventually be rendered to the cache. The Backend will send Renderjobs to the Controller.

    Both of these actions are managed by a [[Scheduler]].

    Whenever something queries a [[Frame]] from the backend it provides hints about what it is doing.
    These hints contain:

    * Timing constraints
    ** When will the [[Frame]] be needed
    ** could we drop the request if it won't be available (rendered) in-time
    * Priority of this job (as soon as possible, or just in time?)
    * action (Playing forward, playing backward, tweaking, playback speed, recursive rendering of dependent frames)

    Notes:
    * The Backend will try to render related frames in groups.
    ** This means that following frames are scheduled with lower priority. Whenever the program really requests them the priority will be adjusted.

    !Description
    This plugin provides a RSSReader for TiddlyWiki
    * It accesses asynchronously an RSSFeed
    *Depending on the chanel item format, each item could be written as :
    **simple text wikified
    **html

    !Usage
    {{{
    <<rssReader noDesc|asHtml|asText rssUrl ['filtering string']>>
    	noDesc: only title of item is printed

    	asHtml: if you know that description contain html (links, img ...),
    		the text is enclosed with <html> </html> tags

     	asText: if the description should not be interpreted as html the
    		description is wikified

    	rssUrl: the rssFeed url that could be accessed.

    	'filtering string': if present, the rssfeed item title must contained
    		this string to be displayed.
    		If 'filering string' contained space characters only, the tiddler
    		title is used for filtering.

    }}}

    For security reasons, if the TiddlyWiki is accessed from http, a ProxyService should be used to access an rssFeed from an other site.

    Scheduling is done with two priority queues, one for high priority jobs and one for low priority jobs. These priority queues are ordered by absolute time values (and a job identifier, details will be worked out at implementation time).

    there are following (non exhaustive) kinds of jobs:
    * start job
    * cancel job, if not finished (abort when out of time)
    * unschedule job

    Jobs implement a kind of future, datastructures which block a querier until data is available.

    The Job scheduler runs singlethreaded. Its only task is to schedule and delegate jobs to worker threads, by itself it will never do any extensive processing!

    Each job has an option what to do when its times expires (abort, proceed).

    The high priority queue is ordered by the __start__ time T, when the job has to be started (plus some hystersis H). A high priority job becomes scheduled beginning with time T but no later than T+H.

    The low priority queue is ordered by __end__ time T, when the job has to be finished (minus a spawn S). Low priority jobs are started as soon as system load permits, the high priority queue is empty (for some usec in future, lets say 100) and the time is earlier than ~T-S. When a job is expired, it is removed from the queue, when it is already running it is handled as defined in its expire policy.

    Canceling and expireing jobs gets noted in Statistics to adjust performance and timings for optimal performance.

    |Name|SplashScreenPlugin|
    |Created by|SaqImtiaz|
    |Location|http://tw.lewcid.org/#SplashScreenPlugin|
    |Version|0.21 |
    |Requires|~TW2.08+|
    !Description:
    Provides a simple splash screen that is visible while the TW is loading.

    !Installation
    Copy the source text of this tiddler to your TW in a new tiddler, tag it with systemConfig and save and reload. The SplashScreen will now be installed and will be visible the next time you reload your TW.

    !Customizing
    Once the SplashScreen has been installed and you have reloaded your TW, the splash screen html will be present in the MarkupPreHead tiddler. You can edit it and customize to your needs.

    !History
    * 20-07-06 : version 0.21, modified to hide contentWrapper while SplashScreen is displayed.
    * 26-06-06 : version 0.2, first release

    !Description
    A set of macros to help you keep track of time estimates for tasks.

    Macros defined:
    * {{{task}}}: Displays a task description and makes it easy to estimate and track the time spent on the task.
    * {{{taskadder}}}: Displays text entry field to simplify the adding of tasks.
    * {{{tasksum}}}: Displays a summary of tasks sandwiched between two calls to this macro.
    * {{{extension}}}: A simple little macro that displays information about a TiddlyWiki plugin, and that will hopefully someday migrate to the TW core in some form.
    Core overrides:
    * {{{wikify}}}: when wikifying a tiddler's complete text, adds refresh information so the tiddler will be refreshed when it changes
    * {{{config.refreshers}}}: have the built-in refreshers return true; also, add a new refresher ("fullContent") that redisplays a full tiddler whenever it or any nested tiddlers it shows are changed
    * {{{refreshElements}}}: now checks the return value from the refresher and only short-circuits the recursion if the refresher returns true

    !!Changes in 1.1.0
    * Made the macros work in nested tiddlers (ie when one tiddler includes another using {{{<<tiddler>>}}} or something similar):
    ** Task summaries in the outer tiddler include the tasks from the inner one
    ** Using the editing shortcuts on the tasks as displayed in the outer tiddler correctly changes the inner tiddler and also redisplays the outer one
    ** Added sanity checks to the editing shortcuts so they will refuse to work if the tiddler has been modified behind their backs
    * Made some small usability fixes:
    ** The "add task" button now responds to the Space key (hat tip: Daniel Baird)
    ** Double-clicking on a completed task's bullet now does the same thing as clicking on the elapsed time: it lets you adjust the time spent, giving you the option of resurrecting the task (hat tip: ~JackF)
    ** Reworked the focus handling of the taskadder macro so it works more intuitively, by refocusing on the same adder you just used

    The task macro provided by the TaskMacroPlugin is for planning, estimating, and tracking detailed tasks such as those required for writing software.  It is inspired by [[Joel Spolsky|http://www.joelonsoftware.com/articles/fog0000000245.html]]'s method for scheduling software development, also popularized by [[Voo2do|http://voo2do.com]] and [[XPlanner|http://xplanner.org]].

    For changes since the previous version, see the TaskMacroReleaseNotes.

    This tutorial leads you through the use of the task macro itself, and supporting macros that summarize lists of tasks and simplify the adding of tasks to a list.  Follow along by clicking the links below.  Or click the little down-arrow next to this tiddler's title, above, and choose "Open all" to have all the tutorial sections displayed at once.

    <!---
    Includes portions of [[TagglyTaggingViewTemplate|http://simonbaird.com/mptw/#TagglyTaggingViewTemplate]], v1.2 (16-Jan-2006).
    Also adds a pair of tasksum macros around the tiddler, to summarize any contained tasks at the top.  Removes the "-" in front of closeTiddler, which can easily bite you if you have a focusable element in a tiddler, such as a taskadder entry field.
    Portions written by Luke Blanshard are hereby released into the public domain.

    ''TextAreaPlugin for TiddlyWiki version 2.0''
    ^^author: Eric Shulman - ELS Design Studios
    source: http://www.elsdesign.com/tiddlywiki/#TextAreaPlugin
    license: [[Creative Commons Attribution-ShareAlike 2.5 License|http://creativecommons.org/licenses/by-sa/2.5/]]^^

    This plugin 'hijacks' the TW core function, ''Story.prototype.focusTiddler()'', so it can add special 'keyDown' handlers to adjust several behaviors associated with the textarea control used in the tiddler editor.  Specifically, it:
    * Adds text search INSIDE of edit fields.^^
    Use ~CTRL-F for "Find" (prompts for search text), and ~CTRL-G for "Find Next" (uses previous search text)^^
    * Enables TAB characters to be entered into field content^^
    (instead of moving to next field)^^
    * Option to set cursor at top of edit field instead of auto-selecting contents^^
    (see configuration section for checkbox)^^
    !!!!!Configuration
    <<<
    <<option chkDisableAutoSelect>> place cursor at start of textarea instead of pre-selecting content
    <<option chkTextAreaExtensions>> add control-f (find), control-g (find again) and allow TABs as input in textarea
    <<<
    !!!!!Installation
    <<<
    Import (or copy/paste) the following tiddlers into your document:
    ''TextAreaPlugin'' (tagged with <<tag systemConfig>>)
    <<<
    !!!!!Revision History
    <<<
    ''2006.01.22 [1.0.1]''
    only add extra key processing for TEXTAREA elements (not other edit fields).
    added option to enable/disable textarea keydown extensions (default is "standard keys" only)
    ''2006.01.22 [1.0.0]''
    Moved from temporary "System Tweaks" tiddler into 'real' TextAreaPlugin tiddler.
