Syntax origin

Nothing on the syntax page is one language. Four independent parsers contribute to this wiki, and knowing which one owns a construct is usually what explains its quirks.

When two of them claim the same characters, DokuWiki connects syntax modes in ascending getSort() order and the first match wins. That single rule decides every collision listed below.

DokuWiki core

Everything here is stock, in inc/Parsing/ParserMode/.

Syntax	Mode	Sort
`====== Heading ======`	Header	50
`//italic//`, `__underline__`, `''mono''`	Formatting	80–100
`<sub>`, `<sup>`, `<del>`	Formatting	110–130
`((footnote))`	Footnote	150
`[[page]]`, `[[wp>page]]`	Internallink	300
bare URLs	Externallink	330
`<[email protected]>`	Emaillink	340
`\\server\share`	Windowssharelink	350
`* item` (two-space bullet)	Listblock	10
`^` / `\|` tables	Table	60
`<code>`, `<file>`	Code, File	200, 210
two-space indent	Preformatted	20
…, `<nowiki>`	Unformatted	170
`\\` plus a space	Linebreak	140
`{{media.png}}`	Media	320
`{{rss>url}}`	Rss	310
`~~NOTOC~~`, `~~NOCACHE~~`	Notoc, Nocache	30, 40
smileys	Smiley + `conf/smileys.conf`	230
`->`, `(c)`, `...`	Entity + `conf/entities.conf`	260
`640x480`	Multiplyentity	270
curly quotes	Quotes	280

So ((...)) is DokuWiki's own footnote syntax, not a Markdown import. Markdown has no footnotes here at all, and [^1] does nothing.

markdowku

lib/plugins/markdowku/syntax/ holds 26 components adding what DokuWiki lacks.

Syntax	Component	Sort
`# Heading`	headeratx	49
Setext headings	headersetext	49
`italic`, `_italic_`	italicasterisk, italicunderline	79
`code`	codespans1–5	95–99
fenced ``` blocks	githubcodeblocks	91
`[text](url)`	anchorsinline	102
`![alt](url)`	imagesinline	101
`<https://example.com>`	autolinks	102
`* item`	ulists	9
`1. item`	olists	9
`> quote`	blockquotes	219
`***`, `___`	hr	8
two trailing spaces	linebreak	139
`\*`, `\_` escapes	escapespecialchars	61

Three collisions are decided here, all of them invisible until they bite:

**bold** is claimed by markdowku's boldasterisk (69) one step ahead of core Formatting's strong (70). Same output, so nobody notices.
> quote is claimed by blockquotes (219) ahead of core Quote (220), which is why quotes here join lines without a space and refuse to nest.
- item is claimed by ulists (9) ahead of core Listblock (10), which is why DokuWiki's ordered-list dash renders as a bullet.

references and anchorsreference exist too, but reference-style links never resolve, hence the gotcha above.

katex

In lib/plugins/katex/, syntax/protect.php (sort 65) only protects math from the wiki parser; script.js does the rendering in the browser.

Syntax	Handled by
$x$ , `$$x$$`	protect.php, then KaTeX client-side
`\NN`…`\CC`	macros in `conf/local.php`

At sort 65 it shadows markdowku's own mathinline (90) and mathblock (89), which never run. That is deliberate: the dollar signs must reach the browser untouched.

texrender

lib/plugins/texrender/ runs LaTeX server-side and inlines the SVG.

Syntax	Component	Sort
`\documentclass{standalone}` …	figure.php	88
`\tikz ... ;` and `\tikz{...}`	inline.php	89

Local core patches

Not plugins, but modifications to DokuWiki itself, tracked in this installation's git repo.

gold links to `(WIP)` pages	`inc/parser/xhtml.php`
