Subject: documentation/doxygen: support \since as labels in entry lists.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~cjwatson/git?a=commitdiff_plain;h=a56227e89de90d0ea5751d0ebfa96734a5e55b96;p=blog.git

documentation/doxygen: support \since as labels in entry lists.

Makes everything much easier to discover. Since I'm by far no longer the
only user, I have a fear of breaking things, so this is completely
opt-in.

Also recognizes a combination of \since and \deprecated as "a version in
which given API got deprecated", expanding the red deprecated label with
a custom text.

+`Version labels`_
+-----------------
+
+By default, to keep compatibility with existing content, the ``@since`` block
+is rendered as a note directly in the text flow. If you enable the
+:ini:`M_SINCE_BADGES` option, content of the ``@since`` block is expected to be
+a single label that can optionally link to a changelog entry. The label is then
+placed visibly next to given entry and detailed description as well as all
+listings. Additionally, if ``@since`` is followed by ``@deprecated``, it adds
+version info to the deprecation notice (instead of denoting when given feature
+was added) --- in this case it expects just a textual info, without any label
+styling. Recommended use is in combination with an alias that takes care of the
+label rendering and  For example (the ``@m_class`` is the same as described in
+`Theme-specific commands`_ above):
+
+.. code:: ini
+
+    M_VERSION_LABELS = YES
+    ALIASES = \
+        "m_class{1}=@xmlonly<mcss:class xmlns:mcss=\"http://mcss.mosra.cz/doxygen/\" mcss:class=\"\1\" />@endxmlonly" \
+        "m_since{2}=@since @m_class{m-label m-success m-flat} @ref changelog-\1-\2 \"since v\1.\2\"" \
+        "m_deprecated_since{2}=@since deprecated in v\1.\2 @deprecated"
+
+With the above configuration, the following markup will render a
+:label-flat-success:`since v1.3` label leading to a page named ``changelog-1-3``
+next to both function entry and detailed docs in the first case, and a
+:label-danger:`deprecated since v1.3` label in the second case:
+
+.. code:: c++
+
+    /**
+    @brief Fast inverse square root
+    @m_since{1,3}
+
+    Faster than `1.0f/sqrt(a)`.
+    */

+    @brief Slow inverse square root

+    Attempts to figure out the value by a binary search.
