From b1912607ae9783d6ccf648bd7706a64eca5bedb9 Mon Sep 17 00:00:00 2001 From: Markus Heiser Date: Sat, 12 Mar 2022 10:18:08 +0100 Subject: [PATCH] [mod] replace /help by /info pages and include pages in project docs This patch implements a bolierplate to share content from info-pages of the SearXNG instance (URL /info) with the project documentation (path /docs/user). The info pages are using Markdown (CommonMark), to include them in the project documentation (reST) the myst-parser [1] is used in the Sphinx-doc build chain. If base_url is known (defined in settings.yml) links to the instance are also inserted into the project documentation:: searxng_extra/docs_prebuild [1] https://www.sphinx-doc.org/en/master/usage/markdown.html Signed-off-by: Markus Heiser --- docs/conf.py | 6 +- docs/src/searx.infopage.rst | 8 ++ docs/user/.gitignore | 1 + docs/user/index.rst | 14 ++- docs/user/search_syntax.rst | 39 ------ manage | 1 + requirements-dev.txt | 1 + searx/{help => info}/en/about.md | 52 ++++---- searx/info/en/search-syntax.md | 35 ++++++ searx/infopage/__init__.py | 191 ++++++++++++++++++++++++++++++ searx/templates/oscar/help.html | 12 -- searx/templates/oscar/info.html | 12 ++ searx/templates/oscar/navbar.html | 2 +- searx/templates/simple/base.html | 2 +- searx/templates/simple/help.html | 12 -- searx/templates/simple/info.html | 14 +++ searx/user_help.py | 61 ---------- searx/webapp.py | 28 +++-- searxng_extra/docs_prebuild | 87 ++++++++++++++ setup.py | 3 +- tests/unit/test_webapp.py | 10 +- 21 files changed, 423 insertions(+), 168 deletions(-) create mode 100644 docs/src/searx.infopage.rst create mode 100644 docs/user/.gitignore delete mode 100644 docs/user/search_syntax.rst rename searx/{help => info}/en/about.md (57%) create mode 100644 searx/info/en/search-syntax.md create mode 100644 searx/infopage/__init__.py delete mode 100644 searx/templates/oscar/help.html create mode 100644 searx/templates/oscar/info.html delete mode 100644 searx/templates/simple/help.html create mode 100644 searx/templates/simple/info.html delete mode 100644 searx/user_help.py create mode 100755 searxng_extra/docs_prebuild diff --git a/docs/conf.py b/docs/conf.py index 2f58bdb12..89d6bb8f6 100644 --- a/docs/conf.py +++ b/docs/conf.py @@ -35,7 +35,7 @@ master_doc = "index" source_suffix = '.rst' numfig = True -exclude_patterns = ['build-templates/*.rst'] +exclude_patterns = ['build-templates/*.rst', 'user/*.md'] import searx.engines import searx.plugins @@ -94,7 +94,6 @@ extlinks['pull-searx'] = ('https://github.com/searx/searx/pull/%s', 'PR ') # links to custom brand extlinks['origin'] = (GIT_URL + '/blob/' + GIT_BRANCH + '/%s', 'git://') extlinks['patch'] = (GIT_URL + '/commit/%s', '#') -extlinks['search'] = (SEARXNG_URL + '/%s', '#') extlinks['docs'] = (DOCS_URL + '/%s', 'docs: ') extlinks['pypi'] = ('https://pypi.org/project/%s', 'PyPi: ') extlinks['man'] = ('https://manpages.debian.org/jump?q=%s', '') @@ -123,8 +122,11 @@ extensions = [ 'linuxdoc.rstFlatTable', # Implementation of the 'flat-table' reST-directive.
