History of the luamplib package
2024/04/12 2.28.0
* provide a new metapost operator 'mplibgraphictext', which is similar
to ConTeXt's 'graphictext'. But the syntax is not the same:
mplibgraphictext "Text" fakebold 2 scale 3
fillcolor red drawcolor blue
where 'fakebold' and 'scale' are fontspec's font options.
'fakebold', 'scale', 'drawcolor' and 'fillcolor' are optional and
default values are '2', '1', "black" and "white" respectively.
When color expressions are given as string, they are regarded as
xcolor's or l3color's expressions. The operator generates a metapost
picture, which can be drawn or assigned to a variable. For compatibilty
with 'graphictext', 'withdrawcolor' and 'withfillcolor' are synonyms of
'drawcolor' and 'fillcolor'. Because the implementation is quite
different from the \ConTeXt's, there are some limitations such that
we can't apply shading (gradient colors) to the text.
* support metafun's new shading method. Color expressions given as string
are regarded as xcolor's or l3color's expressions. Spot colors defined
by the color commands of l3color package are also acceptable
(currently '\DocumentMetadata{ }' is needed for spot colors).
* fix the y-position of text figures, which means the result of 'infont'
operator, not of the 'textext' operator.
2024/04/04 2.27.2
* for warning/info/error messages we now use our own lua function,
instead of ltluatex's. As a result, mplib's multi-line messages are
printed as they are with no module name prepended to each line.
* terminal messages are now much conciser than before, printing only
the most relevant part.
* mplibcode which has no figure output does not print a warning, but
just an info to the log.
2024/03/29 2.27.1
* fix a bug regarding local textext boxes
2024/03/23 2.27.0
* when `mplibcodeinherit' is enabled, `mplibglobaltextext' is implicitly
enabled as well.
* when instance name is used to mplibcode environments, btex ... etex
boxes are also shared among the environments of the same intance name.
* transparency functionality does not conflict with transparent package.
2024/03/10 2.26.4
* not just color names but also color expressions of l3color module
are now supported even if xcolor package is loaded
2024/03/07 2.26.3
* color expressions of l3color are supported as well.
But they are regarded as xcolor's expressions if xcolor package is loaded.
* support pdfmanagement's opacity and shading management.
2024/03/04 2.26.2
* color expressions ('red!50') are supported with xcolor package only
2024/03/04 2.26.1
* attempt to support l3color: \mpcolor{color expression}
* cope with mp.report warning produced by 'message' under metafun
2024/03/01 2.26.0
* when \mplibcachedir{<dir>} is not set, default cache directory will
be in the following order:
$TEXMFVAR/luamplib_cache
$TEXMF_OUTPUT_DIRECTORY/luamplib_cache
./luamplib_cache
$TEXMFOUTPUT/luamplib_cache
.
2024/01/25 2.25.3
* protect "..." even if textextlabel is disabled (revert part of v2.25.0)
2023/12/08 2.25.2
* info instead of warning when compiling with dviluatex
2023/08/21 2.25.1
* explicit \par in \mplibstoptoPDF to support LaTeX's paragraph hooks
2023/08/07 2.25.0
* propagate tex's jobname varible into mplib process as well.
* protect "..." if and only if textextlabel is enabled.
2023/04/04 2.24.0
respect '-recorder' command-line option
2022/01/12 2.23.0
In parellel with the functionality introduced at previous version,
\everymplib (\everyendmplib as well, of course) supports
optional argument of named MetaPost instance, affecting only those
mplibcode environments of the same name.
2022/01/09 2.22.0
* Sergey Slyusarev (@jemmybutton) has suggested and contributed
a new feature for LaTeX mplibcode environment, which now supports
separately named MetaPost instances. Using this feature,
all the variables and functions are shared only among
all the environments belonging to the same instance.
(#99 and #100)
2021/11/23 2.21.1
* address #97 (typesetting fails with "--lua" option)
2021/09/16 2.21.0
* allow empty string in textext()
2021/08/03 2.20.9
* initialize every mplib instance with random integer seed values
2021/08/02 2.20.8
* when \mplibshowlog{enable} is declared, log (not term) messages
returned by mplib instance will be printed into the .log file.
2021/03/11 2.20.7
* emegency patch for context metafun 2021-03-06
2020/12/30 2.20.6
* fix a bug regarding no figure output when luamplib.showlog is
true. (#91)
* now metapost `show' command triggers a warning message, so that
it could be shown on the console. (#91)
2020/02/24 2.20.5
* Extra check for \pdfliteral (PR #89)
* allow expansion of \mpdim and \mpcolor when they are used in
another macro
* step copyright year
2019/12/11 2.20.4
* remove unnecessary setting of endlinechar
* \prependtomplibbox instead of \mplibhmodeornot
2019/11/14 2.20.3
* fix issue #86 (LaTeX command inside metapost label)
2019/10/11 2.20.2
* fix issue #84 (pgf package hinders \mpcolor process)
2019/03/26 2.20.1
* '\mpdim' and '\mpcolor' are allowed, even if '\mplibverbatim' is enabled.
2019/03/20 2.20.0
* huge changes, but mostly internal, so apparently not much difference
from previous version.
* '\mplibforcehmode' makes mplibcode typeset in horizontal mode.
'\mplibnoforcehmode' reverts the setting. The latter is default.
* '\mpliblegacybehavior{disable}' triggers a new mode of processing
verbatimtex .. etex: along with btex .. etex, they will be processed
sequentially one by one. Old behavior, being default, can be restored
by declaring '\mpliblegacybehavior{enable}'.
Incidentally, verbatimtex .. etex in MP input files is honored
from this version, save those that contain '\documentclass'
or '\begin{document}' etc, which is totally ignored.
2018/09/27 2.12.5
* change dash.offset pattern from "%i" to "%f" (PR #77)
* remove unnecessary variables that go back to context (issue #76)
2018/04/16 2.12.4

* address issue #71 "metafun problem: arrow tips are not filled"
by importing luatex-mplib.lua from context beta.
2017/06/02 2.12.1
* when \mplibglobaltextext{enable} is declared, metapost variables
containing btex ... etex labels can be inherited across code chunks.
Of course, \mplibcodeinherit should also be switched on.
2016/03/31 2.11.3
* fix a bug regarding nested mplibcode environments (issue #63)
2016/01/02 2.11.2
* updates for luatex 0.87
2015/10/02 2.11.1
* adapts to latex 2015/10/01 and luatexbase v1.0
* allows `btex ... etex' and `verbatimtex ... etex' even when
`\mplibverbatim{enable}' is declared.
2015/08/01 2.11.0
* after `\mplibverbatim{enable}', contents of mplibcode environment
will be read verbatim. So `btex ... etex', `verbatimtex ... etex',
`\mpdim', `\mpcolor' are not allowed and all TeX commands will be
fed literally into mplib library.
* allow access to type1 fonts, which means we can use glyph
operator now (luatex rev 5266)
* color transparency is now compatible with pgf package and
beamer class as well. (luatex 0.80+ is recommended)
2015/03/26 2.10.1
* fix bug #55 regarding hash token
2015/03/20 2.10.0
* TeX code in `VerbatimTeX()' between `beginfig();' and `endfig;'

`\mpcolor[HTML]{FF0000}'.
2015/01/26 2.9.1
* fix a bug reported by Herbert Schulz via luatex mailing list
(http://tug.org/pipermail/luatex/2015-January/005054.html)
2015/01/05 2.9.0
* after declaring `\mplibcodeinherit{enable}', each mplib code chunks
will inherit variables/constants/macros defined by previous chunks.
On the contrary, the default value `\mplibcodeinherit{disable}' will
treat each code chunks as an independent instance, never being affected
by other code chunks.
2014/07/04 2.8.1
* support color package on plain tex.
* fix a failure at `btex \% etex'.
2014/06/17 2.8.0
* support color/xcolor/spotcolor packages.
On LaTeX, color names or expressions of color/xcolor packages
can be used inside mplibcode environment with the command
\mpcolor{<color expression>}.
2014/04/25 2.7.0
* support DVIPDFMx
* default directory for cache is now '$TEXMFVAR/luamplib_cache'
* internal changes following LuaTeX engine v0.79 and luatexbase
package v0.7
* [fix] avoid luatex crash under math_mode 'decimal'
2014/03/26 2.6.1
* now luamplib does not disregard 'show' command, even if
'luamplib.showlog' is false. Incidentally, it does not raise
error, but just prints a warning, even if output contains
no figure.
* fix a bug wrt color, which might come to the fore under
math mode 'double' or 'decimal'.
2014/03/08 2.6.0
* new macro \mplibtextextlabel{enable} enables string labels typeset
with textext() instead of infont operator. Every string label
thereafter will be typeset with current TeX font.
* fixed a bug wrt btex ... etex parsing (issue #39)
* [doc] added a mention about \MPllx, \MPlly, \MPurx, and \MPury.
2014/03/01 2.5.3
* using \mplibcachedir{<directory path>}, users can change the
directory for storing cache files. By default, it is the directory
where pdf output file is saved.
* at the end of package loading, luamplib searches 'luamplib.cfg',
and, when found, reads the file in automatically.
2014/02/24 2.5.2
* new macros \mplibmakenocache{...} and \mplibcancelnocache{...} to
register/unregister those .mp files that do not need caches.
These macros affect the compilation speed only.
* added a hack to support graph.mp (in fact, format.mp)
* [fix] luamplib now respects percent sign if it is enclosed by quotes.
2014/02/19 2.5
* btex ... etex input from external *.mp files will also be processed
by luamplib. However, verbatimtex ... etex will be entirely ignored
in this case.
2014/02/02 2.4

changed by declaring \mplibnumbersystem{double}. For details, see
http://github.com/lualatex/luamplib/issues/21
2014/01/20 2.3
* \everymplib, \everyendmplib: macros that redefine token lists
\everymplibtoks and \everyendmplibtoks. These will be
automatically inserted at the beginning and ending (respectively)
of each and every mplib code.
* naked TeX codes, includig \mpdim{...}, are allowed inside
mplibcode environment. Refer the manual of gmp package for
details.
2013/12/30 2.2
* start to support transparency/shading under metafun format.
* verbatimtex ... etex just before beginfig() is not ignored.
Using this macro, each mplib box can be moved horizontally and/or
vertically.
2013/12/23 2.1.1
* fix a bug wrt "withoutcolor" option
* fix a bug wrt "char <number> infont <font>" picture
* bypass some ConTeXt commands which raise errors under metafun format
* ignore "fontmapfile <filename>" which isn't needed in mplib
2013/12/19 2.1
* Do not ignore "withcolor" option for textext and normal text object
* verbatimtex ... etex is now just ignored, not raising error
2013/12/11 2.03
* implemented textext() macro which is identical to TEX() from TEX.mp.
TEX() is a synonym of textext().
* fix a bug regarding tex-text box inside for...endfor loop,
reported at http://www.ktug.org/xe/index.php?document_srl=178050

environment caused errors. The character ` was affected too.
2010/12/28 1.07
* fix two bugs reported by Arno Trautmann that made the package crash with
luatex 0.65 (mp 1.5+).
