From c20d22c951e61a06701f6c2201add7c11915e7c5 Mon Sep 17 00:00:00 2001 From: Alex Merry Date: Thu, 10 Apr 2014 21:38:09 +0100 Subject: Add documentation generation using Sphinx This is deliberately modelled very closely on CMake's documentation system. It's a hefty patch, because it involved changing all the documentation to be in reStructuredText format. I also cleaned up the copyright/license statements at the same time. Note that the find modules contain the full license, due to the fact that ecm_use_find_module() copies them out of the ECM distribution. --- docs/sphinx/.gitignore | 1 + docs/sphinx/conf.py.in | 63 ++++++++++ docs/sphinx/ecm.py | 301 ++++++++++++++++++++++++++++++++++++++++++++ docs/sphinx/kde-favicon.ico | Bin 0 -> 1406 bytes docs/sphinx/static/ecm.css | 8 ++ 5 files changed, 373 insertions(+) create mode 100644 docs/sphinx/.gitignore create mode 100644 docs/sphinx/conf.py.in create mode 100644 docs/sphinx/ecm.py create mode 100644 docs/sphinx/kde-favicon.ico create mode 100644 docs/sphinx/static/ecm.css (limited to 'docs/sphinx') diff --git a/docs/sphinx/.gitignore b/docs/sphinx/.gitignore new file mode 100644 index 00000000..0d20b648 --- /dev/null +++ b/docs/sphinx/.gitignore @@ -0,0 +1 @@ +*.pyc diff --git a/docs/sphinx/conf.py.in b/docs/sphinx/conf.py.in new file mode 100644 index 00000000..24ba82c8 --- /dev/null +++ b/docs/sphinx/conf.py.in @@ -0,0 +1,63 @@ +#============================================================================= +# CMake - Cross Platform Makefile Generator +# Copyright 2000-2013 Kitware, Inc., Insight Software Consortium +# +# Distributed under the OSI-approved BSD License (the "License"); +# see accompanying file Copyright.txt for details. +# +# This software is distributed WITHOUT ANY WARRANTY; without even the +# implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. +# See the License for more information. +#============================================================================= +import sys +import os +import re +import glob + +sys.path.insert(0, r'@conf_path@') + +source_suffix = '.rst' +master_doc = 'index' + +project = 'Extra CMake Modules' +copyright = 'KDE Developers' +version = '@conf_version@' # feature version +release = '@conf_release@' # full version string + +primary_domain = 'ecm' + +exclude_patterns = [] + +extensions = ['ecm'] +templates_path = ['@conf_path@/templates'] + +ecm_manuals = sorted(glob.glob(r'@conf_docs@/manual/*.rst')) +ecm_manual_description = re.compile('^\.\. ecm-manual-description:(.*)$') +man_pages = [] +for fpath in ecm_manuals: + try: + name, sec, rst = os.path.basename(fpath).split('.') + desc = None + f = open(fpath, 'r') + for l in f: + m = ecm_manual_description.match(l) + if m: + desc = m.group(1).strip() + break + f.close() + if desc: + man_pages.append(('manual/%s.%s' % (name, sec), + name, desc, [], int(sec))) + else: + sys.stderr.write("ERROR: No ecm-manual-description in '%s'\n" % fpath) + except Exception, e: + sys.stderr.write("ERROR: %s\n" % str(e)) +man_show_urls = False + +html_show_sourcelink = True +html_static_path = ['@conf_path@/static'] +html_style = 'ecm.css' +html_theme = 'default' +html_title = 'Extra CMake Modules %s Documentation' % release +html_short_title = '%s Documentation' % release +html_favicon = '@conf_path@/kde-favicon.ico' diff --git a/docs/sphinx/ecm.py b/docs/sphinx/ecm.py new file mode 100644 index 00000000..9b76e1a9 --- /dev/null +++ b/docs/sphinx/ecm.py @@ -0,0 +1,301 @@ +# Copyright 2014 Alex Merry +# Based on cmake.py from CMake: +# Copyright 2000-2013 Kitware, Inc., Insight Software Consortium +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions +# are met: +# +# 1.
