-## Read the Docs theme skin
+## HTML theme

-The HTML output keeps the existing `basicstrap` Sphinx theme, then applies the
-ZoiteChat main-site skin from `_static/css/zoitechat-docs.css`.
+The `zoitechat` theme inherits Sphinx's built-in `basic` theme. It uses the
+same compact layout, blue navigation, and system fonts as zoitechat.org.
+Appearance starts in System mode on each page. Light and Dark are available
+for the current page; no cookies or browser storage are used.

-Brand navigation links are set in `conf.py` through `html_context`, and the
-header logo uses `_static/zoitechat-logo.svg`.
+The theme's templates are in `_theme/zoitechat/`. Its readable CSS and
+JavaScript are in `_static/css/zoitechat-docs.css` and
+`_static/js/zoitechat-docs.js`. No minification, JavaScript package manager,
+external fonts, or CDN assets are required.
+
+Navigation URLs, including `zoite_atlas_url`, are configured through
+`html_context` in `conf.py`. The logo
+is `_static/zoitechat-logo.svg`. Standard Sphinx search, indexes, source
+links, anchors, translations, and previous/next links remain available.
+The HTML output also works as locally installed documentation; project-site
+links only access the network when clicked.
+
+Build from the repository root:
+
+```sh
+sphinx-build -b html docs docs/_build/html
+```
+
+Use a clean output directory when switching themes, so stale Basicstrap
+assets from an earlier build are not included in a package.
+
+## Debian packaging
+
+The active theme does not use the bundled Basicstrap, Bootstrap, jQuery,
+jQuery Cookie, Font Awesome, or icon fonts. Its font stack includes DejaVu
+Sans and DejaVu Sans Mono; no font files are bundled by the theme.
+
+Packagers may exclude `docs/_theme/basicstrap/` from the source package.
+The default theme continues to build without that directory. No pre-minified
+third-party assets need to be added or rebuilt for this theme.
+
+Build with the distribution's `python3-sphinx`. After installing the HTML
+into the package staging directory, use `dh_sphinxdoc` (or `dh --with
+sphinxdoc`) to replace Sphinx's standard JavaScript files with system
+symlinks. Include `${sphinxdoc:Depends}` in the package dependencies and
+`${sphinxdoc:Built-Using}` where required for generated assets. The custom
+`zoitechat-docs.js` remains a small, readable project source file.
+
+A built-in theme is still selectable with `-D html_theme=classic` if a
+packager needs a different layout. The old RST content has existing build
+diagnostics; changing the theme does not suppress or alter them.

ThePeGaSuS	c51f885253	add option to align wrapped lines under the nick or message When nick indentation is off, lines after the first wrap back to the left edge, under the timestamp. Add a text_wrap_align preference (start of line, prefix, message) so they can line up under the nick or the message text instead. It is applied at wrap time, so existing scrollback is re-wrapped when the setting changes, and the menu is greyed out while nick indentation is on.	2026-10-12 17:43:09 +02:00

BareMetal	0a4367b1da	fix(xtext): move hexcolor_parse to its own file for the standalone xtext tests master's new xtext_tests target compiles xtext.c on its own with only GTK linked, so hexcolor_parse cannot live in util.c. Keep it in a dependency-free hexcolor.c that both test targets compile, and register it in the Visual Studio project for the Windows build.
