"""Generates Nvim :help docs from C/Lua docstrings, using Doxygen.
|
|
|
|
Also generates *.mpack files. To inspect the *.mpack structure:
|
|
|
|
:new | put=v:lua.vim.inspect(msgpackparse(readfile('runtime/doc/api.mpack')))
|
|
|
|
|
|
Flow:
|
|
main
|
|
extract_from_xml
|
|
fmt_node_as_vimhelp \
|
|
para_as_map } recursive
|
|
update_params_map /
|
|
render_node
|
|
|
|
This would be easier using lxml and XSLT, but:
|
|
|
|
1. This should avoid needing Python dependencies, especially ones that are
|
|
C modules that have library dependencies (lxml requires libxml and
|
|
libxslt).
|
|
2. I wouldn't know how to deal with nested indentation in <para> tags using
|
|
XSLT.
|
|
|
|
Each function :help block is formatted as follows:
|
|
|
|
- Max width of 78 columns (`text_width`).
|
|
- Indent with spaces (not tabs).
|
|
- Indent of 16 columns for body text.
|
|
- Function signature and helptag (right-aligned) on the same line.
|
|
- Signature and helptag must have a minimum of 8 spaces between them.
|
|
- If the signature is too long, it is placed on the line after the helptag.
|
|
Signature wraps at `text_width - 8` characters with subsequent
|
|
lines indented to the open parenthesis.
|
|
- Subsection bodies are indented an additional 4 spaces.
|
|
- Body consists of function description, parameters, return description, and
|
|
C declaration (`INCLUDE_C_DECL`).
|
|
- Parameters are omitted for the `void` and `Error *` types, or if the
|
|
parameter is marked as [out].
|
|
- Each function documentation is separated by a single line.
