\ProvidesFile{sphinxlatexadmonitions.sty}[2024/07/01 v7.4.0 admonitions]

% Provides support for this output mark-up from Sphinx latex writer:
%
% - sphinxseealso environment added at 6.1.0.
%
% At 7.4.0 it too now uses sphinxheavybox, and has the same associated
% sphinxsetup CSS keys as admonitions do.
%
% - 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.
%
% At 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.
%
% - The default sphinxnote, sphinxwarning, etc... use associated
%   one-argument macros \sphinxstylenotetitle, \sphinxstylewarningtitle, etc
%   which can be redefined.  Their default is to use \sphinxdotitlerowwithicon
%   to typeset the title in a coloured header row at top of the
%   admonition. (new with 7.4.0)
%
% The sphinxlightbox environment is kept for backward compatiblity, 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).

%
% Requires:
\RequirePackage{sphinxpackageboxes}
% 7.4.0 removes unneeded \spx@boxes@border
\RequirePackage{framed}% used by sphinxheavybox
%
% 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 (for sphinxheavybox)

% Provides: (also in sphinxlatexliterals.sty)
% Only needed here by legacy (deprecated) sphinxlightbox environment.

% Since 1.5 these environments are named individually sphinxnote, sphinxhint,
% etc... to allow user to redefine them entirely.
%
% The Sphinx definitions for note/hint/important/tip notices were done like
% this, prior to 6.2.0:
%
% \newenvironment{sphinxhint}[1]
%   {\begin{sphinxlightbox}\sphinxstrong{#1} }{\end{sphinxlightbox}}
%
% Then from 6.2.0 to 7.4.0 (exclusive) a more complex definition decided
% to use either sphinxlightbox or sphinxheavybox according to whether
% some CSS-like options had been used, for example for a background color.
%
% 6.2.0 also added one layer of mark-up via \sphinxnotetitle etc..., because
% the former \sphinxstrong{#1}<space> used a too generic \sphinxstrong.
%
% At 7.4.0, sphinxheavybox environment is default for all types of notices
% and also for the seealso and todo directives.
%
% Code adapted from framed.sty's "snugshade" environment.
% Nesting works (inner frames do not allow page breaks).

   % Then \fcolorbox was used with \fboxrule set to \FrameRule and \fboxsep
   % set to \FrameSep.

   }% 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.
%
% MEMO: direct usage of these environments does not execute the div.<type>_TeXextras
% and div.<type>_TexColor code, there are only done from the sphinxadmonition wrapper.

% A utility to remove a final colon.  Removing last token is not easy in

% - the generic admonition ends up using "note", so for \sphinxnotetitle to

% - a bit far-fetched but maybe there is more than one colon inside the input
