 <<.from-version "5.2.6">>

+The <<.op makepatches>> operator uses up to two suffixes:
+
+* <<.place T>> (diff mode): `lines` to operate in line mode, `words` to operate in word mode. If omitted (default), the algorithm operates in character mode.
+* <<.place F>> (output format): <<.from-version "5.5.0">> `json` to output a structured JSON array of differences instead of a standard patch string. To use the JSON output with the default character mode, skip the first suffix with a double colon (e.g., `makepatches::json`).
+
 The difference algorithm operates in character mode by default. This produces the most detailed diff possible. In `words` mode, each word in the input text is transformed into a meta-character, upon which the algorithm then operates. In the default character mode, the filter would find two patches between "ActionWidget" and "Action-Widgets" (the hyphen and the plural s), while in `words` mode, the whole word is found to be changed. In `lines` mode, the meta-character is formed from the whole line, delimited by newline characters, and is found to be changed independent of the number of changes within the line.

 The different modes influence the result when the patches are applied to texts other than the original, as well as the runtime.

 <<.tip "The calculation in `words` mode is roughly 10 times faster than the default character mode, while `lines` mode can be more than 100 times faster than the default.">>

+description: A field name containing round brackets can no longer be used as a filter operator suffix, because `(` now starts a multi value variable operand.
+
+Two filter operators take a field name in the suffix position: `regexp` and `search`. Up to 5.3.8 such a field name could contain round brackets, for example:
+
+```
+[regexp:_cd-work(s)[(?i)suite]]
+[search:_cd-work(s)[suite]]
+```
+
+In 5.4.0 the new `(varname)` operand syntax for [[Multi-Valued Variables]] makes `(` start an operand. The parser now splits such a field name at the `(`, so the filter no longer matches.
+
+This will not be fixed. The two readings of `field(x)`, a field named `field(x)` versus the field `field` with the operand `(x)`, are genuinely ambiguous, so `(` and `)` are reserved in filter operator names and suffixes from 5.4.0 onwards.
+
+Workaround: do not use `(` or `)` in field names that are referenced as a filter operator suffix. Rename the field, for example `_cd-works`.

-description: Filesystem dynamic stores with live reload via chokidar
-release: 5.5.0
-tags: $:/tags/ChangeNote
-change-type: feature
-change-category: nodejs
-github-links: https://github.com/TiddlyWiki/TiddlyWiki5/pull/9806
-github-contributors: Jermolene
-
-The filesystem syncadaptor can now be configured to treat a folder as a [[dynamic store|tiddlywiki.files Files]]: tiddlers in the folder are loaded at boot, a configurable filter decides which tiddlers are saved back into that folder instead of the default `tiddlers/` directory, and external edits to files in the folder are picked up live by a [[chokidar|https://github.com/paulmillr/chokidar]] watcher.
-
-Dynamic stores are declared inside a `tiddlywiki.files` specification via the new `dynamicStore` property on a directory entry. For example, the following declaration loads every `.md` file in a sibling `content/` folder, routes any tiddler with `type: text/x-markdown` back to that folder on save, and hot-reloads changes made by an external editor:
-
-```
-{
-    "directories": [{
-        "path": "../content",
-        "filesRegExp": "^.*\\.md$",
-        "isTiddlerFile": true,
-        "dynamicStore": {
-            "saveFilter": "[type[text/x-markdown]]",
-            "watch": true,
-            "debounce": 400
-        }
-    }]
-}
-```
-
-Notes:
-
-* File events are debounced per file (default 400ms, configurable via `debounce`) to cope with editors that save atomically via rename.
-* Each detected change is diffed against the current in-wiki tiddler before being reported, so self-writes performed by TiddlyWiki itself do not cause reload loops.
-* Deletions on disk propagate to the wiki via the syncer's standard server-side-deletion path.
-* JavaScript module tiddlers (those with `type: application/javascript` and a `module-type` field) are never hot-reloaded; reloading them would require restarting the TiddlyWiki process.
-
-This feature adds [[chokidar|https://github.com/paulmillr/chokidar]] as a new runtime dependency of TiddlyWiki on Node.js.

- `created`, `modified` are emitted as ISO-8601 strings (symmetric with

- `type` is skipped when it equals `text/x-markdown` (the default for `.md` files).
- `bag`, `revision` are skipped (sync metadata, not authored content).
- List fields (those with a registered `stringify` method) are emitted as YAML arrays.

Mario PietschandGitHub	97e27d0dad	Fix regex for code block end detection in wikiparser (#9739 ) * Fix regex for code block end detection in wikiparser * Anchor the codeblock end fence to its own line Close an empty code block without consuming the tiddler, while a fence only counts when it stands alone on its line. * Match the end fence with (^\|\r?\n) so the empty block case closes at the line start and a code line ending in ``` stays inside the block * Add test-codeblock-parser.js covering empty blocks with language and CRLF, delimiter newline handling, mid-line fences and a missing fence	2026-07-22 13:12:55 +02:00
