\ProvidesPackage{sphinxlatexadmonitions}[2024/10/11 v8.1.1 admonitions]
|
|
|
|
% Provides support for this output mark-up from Sphinx latex writer:
|
|
%
|
|
% - sphinxseealso environment added at 6.1.0.
|
|
%
|
|
% - sphinxtodo environment added at 7.4.0.
|
|
%
|
|
% - sphinxadmonition (environment)
|
|
% This is a dispatch which formerly configured
|
|
%
|
|
% - note, hint, important, tip to use sphinxlightbox (or optionally
|
|
% sphinxheavybox since 6.2.0),
|
|
% - warning, caution, attention, danger, error to use sphinxheavybox.
|
|
%
|
|
% Since 7.4.0 all admonitions use sphinxheavybox.
|
|
%
|
|
% - All environments sphinxnote, sphinxwarning, etc... can be redefined as
|
|
% will by user. Thay have a single parameter #1 which is the title.
|
|
%
|
|
% - Also redefinable by user are the one-argument commands
|
|
% * \sphinxstylenotetitle,
|
|
% * \sphinxstylewarningtitle,
|
|
% * etc.... one for each admonition type (also seealso and todo).
|
|
%
|
|
% - At 7.4.0, all commands of previous item use \sphinxdotitlerow.
|
|
% (the 7.4.0 name, still usable, was \sphinxdotitlerowwithicon; the 8.1.0
|
|
% version is also used for topic, contents and sidebar directives, see
|
|
% sphinxlatexshadowbox.sty, and handles both "with icon" and "without
|
|
% icon" situations).
|
|
%
|
|
% The sphinxlightbox environment is kept for backward compatibility, for user
|
|
% custom code which used it via custom definitions done in preamble or via
|
|
% raw latex directive.
|
|
% MEMO: here is for example how sphinxnote was formerly defined:
|
|
% (where #1 is the localized string Note, followed with a colon)
|
|
% \newenvironment{sphinxnote}[1]
|
|
% {\begin{sphinxlightbox}\sphinxstrong{#1} }
|
|
% {\end{sphinxlightbox}}
|
|
% Use this if you want to revert the 7.4.0 switch to usage of sphinxheavybox.
|
|
% (the 7.4.0 redefined \sphinxstylenotetitle will not work in sphinxlightbox,
|
|
% so \sphinxstrong{#1}<space> which was its former default is used above).
|
|
|
|
% Dependencies (they do not need to be defined at time of loading):
|
|
%
|
|
% - of course the various colour and dimension options handled via sphinx.sty
|
|
% - dimension register \spx@image@maxheight from sphinxlatexgraphics.sty
|
|
% - \savenotes/\spewnotes from sphinxpackagefootnote.sty
|
|
% - \ifspx@inframed defined in sphinx.sty
|

% - \spx@boxes@fcolorbox@setup from sphinxpackageboxes.sty
|
|
%
|
|
\RequirePackage{framed}

}% end of sphinxheavybox environment definition
|
|
|
|
% - Since 1.5 these environments are named individually to allow user to
|
|
% redefine them entirely.
|
|
%
|
|
% - Since 5.1.0, sphinxheavybox is more versatile and four border widths, four
|
|
% padding widths, four corner radii, optional shadow, and three colors can all
|
|
% be modified via CSS-named alike options.
|
|
%
|
|
% - Since 6.2.0, also note/hint/important/tip notices can use these options
|
|
% and then they go automatically via sphinxheavybox. If only the legacy options
|
|
% are used, they keep using sphinxlightbox.
|
|
%
|
|
% - Since 6.2.0, \sphinxwarningtitle etc... add one level of mark-up (they
|
|
% expand to \sphinxstrong{#1}<space> which was former hard-coded mark-up).
|
|
% Example:
|
|
% \renewcommand{\sphinxwarningtitle}[1]{\textbf{#1}\par\smallskip
|
|
% {\color{sphinxwarningBorderColor}\hrule height1pt}\smallskip}
|
|
%
|
|
% - Since 7.4.0, all types of notices use sphinxheavybox and the default
|
|
% for \sphinxstyle<type>title is mapped to using \sphinxdotitlerowwithicon{<type>}
|
|
%
|
|
% MEMO: except for the generic admonition directive (which uses "note" type)
|
|
% the argument #1 in these environments has a postfixed colon originating
|
|
% in Sphinx LaTeX writer legacy code. The
|
|
% \sphinxremovefinalcolon utility in sphinxlatexstyletext.sty can be used as
|
|
% \sphinxremovefinalcolon{#1} from inside the definitions of
|
|
% \sphinxstylenotetitle et al. commands.
|
|
|
|
% Important: even prior to 5.1.0 it was not really possible to use directly
|
|
% sphinxheavybox if not triggered from sphinxadmonition, because some
|
|
% parameters were defined in sphinxadmonition. This meant that the
|
|
% sphinxwarning, sphinxcaution etc... environments (defined below) could not
|
|
% be used directly in a document, they had to be triggered via
|
|
% sphinxadmonition. The sole data since 5.1.0 needed by sphinxheavybox is the
|
|
% type of the notice which sphinxadmonition stores into \spx@noticetype.
|
|
%
|
|
% In order to facilitate recycling or imitation of the sphinx<type>
|
|
% environments, 7.4.0 inserts an extra \def\spx@noticetype{<type>} in their
|
|
% definitions, so that they can be used independently of sphinxadmonition
|
|
% dispatcher.
