From a3dcf1e004f45cb973be8ec2b063b9f00d44b872 Mon Sep 17 00:00:00 2001 From: Tatsuhiro Tsujikawa Date: Sat, 10 Jan 2015 00:37:42 +0900 Subject: [PATCH] Produce man pages using sphinx Previously to create manual page for bundled programs, we use help2man to create man page from program's help output. Then our man2rst.py script converts man page to rst document. Sphinx generates html from rst documents. Now help2rst.py produces rst document from programs output. We use Sphinx solely to produce both man pages and html files. --- doc/Makefile.am | 2 +- doc/conf.py.in | 10 +- doc/h2load.1 | 125 +++++++-- doc/h2load.1.rst | 53 ++-- doc/h2load.h2m | 3 - doc/h2load.h2r | 4 + doc/nghttp.1 | 178 +++++++++---- doc/nghttp.1.rst | 52 +--- doc/nghttp.h2m | 3 - doc/nghttp.h2r | 4 + doc/nghttpd.1 | 147 ++++++++--- doc/nghttpd.1.rst | 47 +--- doc/nghttpd.h2m | 3 - doc/nghttpd.h2r | 4 + doc/nghttpx.1 | 635 +++++++++++++++++++++++++++++++++------------- doc/nghttpx.1.rst | 366 +++++++++++++------------- doc/nghttpx.h2m | 3 - doc/nghttpx.h2r | 28 ++ help2rst.py | 178 +++++++++++++ makemanpages | 23 +- man2rst.py | 121 --------- src/h2load.cc | 17 +- src/nghttpd.cc | 3 +- src/shrpx.cc | 46 ++-- 24 files changed, 1306 insertions(+), 749 deletions(-) delete mode 100644 doc/h2load.h2m create mode 100644 doc/h2load.h2r delete mode 100644 doc/nghttp.h2m create mode 100644 doc/nghttp.h2r delete mode 100644 doc/nghttpd.h2m create mode 100644 doc/nghttpd.h2r delete mode 100644 doc/nghttpx.h2m create mode 100644 doc/nghttpx.h2r create mode 100755 help2rst.py delete mode 100755 man2rst.py diff --git a/doc/Makefile.am b/doc/Makefile.am index 544f42e3..a9d34049 100644 --- a/doc/Makefile.am +++ b/doc/Makefile.am @@ -176,7 +176,7 @@ text: @echo @echo "Build finished.
