when to use state tiddlers and when temp tiddlers

[Mohammad]

Tiddlywiki stores global variables in tiddler fields.

For example all state tiddlers in widgets like reveal, checkbox, edit-text, ...

Considering both single file wiki and Node.js wiki what are your recommendation in using

• $:/temp/mytiddlers
• $:/state/mytiddlers

[Eric Shulman]

Both $:/temp and $:/state are ignored when determining if the document is "dirty" (see $:/core/SaverFilter)... and by default both are saved when you save the file (except for $:/state/popup, which are NOT saved... see $:/core/save/all)

However, conceptually, $:/temp tiddlers should be "throw-away"... able to be discarded when not actually in use, while $:/state tiddlers should reasonably be expected to persist across sessions.

To enforce this difference, I routinely create a tiddler, tagged with $:/tags/Macro, containing:

\define publishFilter() -[prefix[$:/temp]]

This variable is automatically included by the $:/core/save/all filter.  The effect is that $:/temp tiddlers are NOT saved when you save the file and are, in effect, automatically discarded at the end of the session.

Thus, if I want a reveal state to always revert to closed on startup, I will use a $:/temp tiddler, but if I want the reveal state to persist across sessions, I will use a $:/state tiddler

Eric,

Nice answer.

However did you mean $:/config/SaverFilter?

for detecting dirty?

The fact that the dirty indicator is different from what gets saved is a useful fact and possible trick.

see https://tiddlywiki.com/prerelease/#SavingMechanism  point 4

The publishFilter variable will start to work with TW 5.1.22 see: https://tiddlywiki.com/prerelease/#TiddlyWiki%20Pre-release

and https://github.com/Jermolene/TiddlyWiki5/issues/4252

Good links Mario!

Thanks

I confused about this!

By dirty saving does it mean sync on node.js or pushing the save button and create a single file?

I use a tiddler with $:/state prefix to keep the status of a $reveal widget between two sessions and I use node.js

When I reload the wiki, I see TW has deleted all $:/state tiddlers, so I cannot keep the status!

This is the code I used to reproduce the issue

<$reveal type=match state="$:/state/tid" text="show" defualt=show>
State is exist and its value is //show//
</$reveal>
<$reveal type=nomatch state="$:/state/tid" text="show" defualt=show>
State tiddler is not exist or its value is //hide//
</$reveal>

<$button>
<$list filter="[[$:/state/tid]get[text]match[show]]" emptyMessage="""Show <$action-setfield $tiddler="$:/state/tid" text="show"/>""">
Hide <$action-setfield $tiddler="$:/state/tid" text="hide"/>
</$list>
</$button>

On node.js TW seems deletes $:/state tiddlers!

Thank in advance

I use $:/keepstate prefix!

This is different from Tiddlywiki recommendation, but I can remember these are not real tiddlers and I can delete them using AdvancedSearch or Commander.

Hi,

The node server uses a config tiddler  https://tiddlywiki.com/#%24%3A%2Fconfig%2FSyncFilter  to sync info back to the server. As you can see the default setting contains:

[is[tiddler]] -[[$:/HistoryList]] -[[$:/Import]] -[[$:/isEncrypted]] -[prefix[$:/status/]] -[prefix[$:/state/]] -[prefix[$:/temp/]]

Just remove the -[prefix[$:/state/]] element from the filter and the state info will be saved back. .. Or use a different name as Mohammad wrote.
