From 398f7abdcb7e2307facebcbdae5639f7d35916cd Mon Sep 17 00:00:00 2001 From: Akira Yokosawa Date: Fri, 18 Feb 2022 23:11:17 +0900 Subject: [PATCH] docs: pdfdocs: Pull LaTeX preamble part out of conf.py Quote from Jon's remark [1]: I do notice that Documentation/conf.py is getting large and unapproachable. At some future point, it might be nice to pull all of the latex stuff out into a separate file where it won't scare people who stumble into it by accident. Pull LaTeX preamble settings added since commit 3b4c963243b1 ("docs: conf.py: adjust the LaTeX document output") out into sphinx/kerneldoc-preamble.sty. It will be copied to the build directory by the added "latex_additional_files" setting in conf.py. As a bonus, LaTeX/TeX code can be maintained without escaping backslashes. To compensate the loss of change history in sphinx/kerneldoc-preamble.sty, here is a list of changes made in conf.py: - f7ebe6b76940 ("docs: Activate exCJK only in CJK chapters") - 0afd4df0d16a ("docs: pdfdocs: Prevent column squeezing by tabulary") - 659653c9e546 ("docs: pdfdocs: Refactor config for CJK document") - e291ff6f5a03 ("docs: pdfdocs: Add CJK-language-specific font settings") - 7eb368cc319b ("docs: pdfdocs: Choose Serif font as CJK mainfont if possible") - 35382965bdd2 ("docs: pdfdocs: Preserve inter-phrase space in Korean translations") - 77abc2c230b1 ("docs: pdfdocs: One-half spacing for CJK translations") - 788d28a25799 ("docs: pdfdocs: Permit AutoFakeSlant for CJK fonts") - 29ac9822358f ("docs: pdfdocs: Teach xeCJK about character classes of quotation marks") - 7c5c18bdb656 ("docs: pdfdocs: Fix typo in CJK-language specific font settings") - aa872e0647dc ("docs: pdfdocs: Adjust \headheight for fancyhdr") - 8716ef413aa5 ("docs: pdfdocs: Tweak width params of TOC") - 66939df53948 ("docs: pdfdocs: Switch default CJK font to KR variants") - 7b686a2ea1e4 ("docs: pdfdocs: Enable CJKspace in TOC for Korean titles") - 5d9158e3c762 ("docs/translations: Skip CJK contents if suitable fonts not found") - b774cc46313b ("docs: pdfdocs: Move CJK monospace font setting to main conf.py") [1]: https://lore.kernel.org/all/87zgmr66cn.fsf@meer.lwn.net/ Suggested-by: Jonathan Corbet Signed-off-by: Akira Yokosawa Link: https://lore.kernel.org/r/aaa9dca1-27c0-c414-77f3-c5587db0cc5b@gmail.com Signed-off-by: Jonathan Corbet --- Documentation/conf.py | 184 ++-------------------------- Documentation/sphinx/kerneldoc-preamble.sty | 184 ++++++++++++++++++++++++++++ 2 files changed, 197 insertions(+), 171 deletions(-) create mode 100644 Documentation/sphinx/kerneldoc-preamble.sty diff --git a/Documentation/conf.py b/Documentation/conf.py index fb8f69fc4d38..072ee31a301d 100644 --- a/Documentation/conf.py +++ b/Documentation/conf.py @@ -409,188 +409,25 @@ latex_elements = { # Additional stuff for the LaTeX preamble.
