OpenMP LLVM Documentation

OpenMP LLVM's documentation is written in reStructuredText, a lightweight plaintext markup language (file extension

). While the reStructuredText documentation should be quite readable in source form, it is mostly meant to be processed by the Sphinx documentation generation system to create HTML pages which are hosted on https://llvm.org/docs/ and updated after every commit. Manpage output is also supported, see below.

If you instead would like to generate and view the HTML locally, install Sphinx http://sphinx-doc.org/ and then do:

cd <build-dir>
cmake -DLLVM_ENABLE_SPHINX=true -DSPHINX_OUTPUT_HTML=true -DCMAKE_MODULE_PATH=/path/to/llvm/cmake/modules <src-dir>
make docs-openmp-html
$BROWSER <build-dir>/docs/html/index.html

The mapping between reStructuredText files and generated documentation is

<->

<build-dir>/projects/openmp/docs//html/Foo.html

<->

https://openmp.llvm.org/docs/Foo.html

.

If you are interested in writing new documentation, you will want to read

which will get you writing documentation very fast and includes examples of the most important reStructuredText markup syntax.

Manpage Output

Building the manpages is similar to building the HTML documentation. The primary difference is to use the

makefile target, instead of the default (which is

html

). Sphinx then produces the man pages in the directory

<build-dir>/docs/man/

.

cd <build-dir>
cmake -DLLVM_ENABLE_SPHINX=true -DSPHINX_OUTPUT_MAN=true <src-dir>
make
man -l >build-dir>/docs/man/FileCheck.1

The correspondence between .rst files and man pages is

<->

<build-dir>/projects/openmp/docs//man/Foo.1

. These .rst files are also included during HTML generation so they are also viewable online (as noted above) at e.g.

https://openmp.llvm.org/docs/CommandGuide/Foo.html
