History of the luamplib package 2024/12/16 2.36.3 * change '//' to 'math.floor' for compatibility with luajittex (#158) * fix documentation on mplibgraphictext considering the introduction of 'withshadingmethod' 2024/12/11 2.36.2 * fix a bug regarding expansion of options (https://tug.org/pipermail/metapost/2024-December/003574.html) 2024/12/09 2.36.1 * fix a bug of previous release: missing 'local' in front of 'os' 2024/12/08 2.36.0 * | withshadingmethod , where shall be "linear" or "circular", gives shading effect to the or with plain format as well as metafun. See the documentation. * withtransparency (|, ) gives transparency effect with plain format as well. See the documentation. * added 'dir TLT' to usemplibgroup boxes * removed 'tag=artifact' option. Use 'artifact' instead. 2024/11/28 2.35.2 * fix height/depth of boxes made by \mplibgroup command * enhanced tagging of \usemplibgroup 2024/11/25 2.35.1 * cope with 'TEX(char13)': remove everything from char13 to the end of input string (https://tug.org/pipermail/metapost/2024-November/003572.html) * (WIP) avoid internal command names of tagpdf/kernel code (#151) 2024/11/12 2.35.0 * even under \mplibtextextlabel{true}, the original 'infont' operator will be used when the character slot of the text argument is less than 32, or is equal to 35, 36, 37, 38, 92, 94, 95, 123, 125, 126 or 127. * \mplibforcehmode will have effects on \usemplibgroup as well as ordinary metapost figures. * support tagged PDF when tagpdf package is activated. The related code is currently in experimental stage. See the documentation for details. 2024/08/03 2.34.5 * provide 'withgroupbbox' macro for transparency group to enable users to control the bounding box * write down the width/height/depth values of mplibgroup to the log file 2024/07/31 2.34.4 * 'withpattern' operator accepts a as well as a for its operand. Thus users can give pattern effect to the result of btex command or infont operator. * fix regarding line width in mplibgraphictext 2024/07/27 2.34.3 * in DVI mode, use LaTeX's shipout hooks to generate new XObjects or to put resources to pageresources. (in plain, load atbegshi.sty) * fix shading to allow the even-odd rule 2024/07/24 2.34.2 * With the newly introduced macros, \mplibgroup ... \endmplibgroup, users can define a transparency group or a normal form XObject from TeX side. The LaTeX environment 'mplibgroup' is identical to this pair of macros. See the document for details. * document: be more precise about the color effect of a transparency group * remove trailing zeros from numeric objects to get smaller PDF 2024/07/19 2.34.1 * transparency group is available with plain format as well. * transparency group once used is reusable in the TeX code or in other MetaPost code chunks. see the document for details. 2024/07/17 2.34.0 * support transparency group with metafun format * fix regarding default value in circular fading mode * fix regarging the scope of graphics state 2024/07/14 2.33.1 * refactor the manual, including some minor items undocumented so far * improve fading routine to get possibly smaller pdf file 2024/07/08 2.33.0 * provide a new metapost operator 'withfademethod' and related macros, which make the color of an object gradiently transparent. see luamplib document for details. * fix spot-color shading routine to support user-defined colorspace 2024/07/03 2.32.4 * make the variable 'patterns' local * 'math.randomseed' on plain TeX * remove redundant code 'fullcircle scaled 0' 2024/06/21 2.32.3 * 'coloured' is a synonym of the option 'colored' in pattern definition. * fix a bug related to pdf page resources in dvi mode * users can access the lua table containing mplib instances 'luamplib.instances', through which metapost variables are also easily accessible as documented in LuaTeX manual 11.2.8.4. 2024/06/14 2.32.2 * fix matrix conversion between MP and PDF 2024/06/13 2.32.1 * for the sake of convenience, width and height values of tiling patterns will be written down into the log file. * table type is allowed as well as string type for 'matrix' and 'bbox' options in pattern definition. * metapost code such as 'rotated 30 slanted .2' is allowed as well as the string or table of numbers for the 'matrix' option in pattern definition. * as for the 'resources' option in pattern definition, luamplib automatically includes the resources of the current page. * luamplib does not log info even if there's no beginfig ... endfig. 2024/06/10 2.32.0 * \mppattern{} ... \endmppattern defines a tiling pattern which can be used with 'withpattern' operator to fill a closed path by replicating the tile horizontally and vertically. \begin{mppattern} ... \end{mppattern} is exactly the same as \mppattern ... \endmppattern. See luamplib manual for details. 2024/05/30 2.31.2 * support vertical writing mode in mpliboutlinetext (presently luatexko package only, and except horizontal mode inside vertical mode) * after the process of mpliboutlinetext, mpliboutlinepic[1] ... mpliboutlinepic[mpliboutlinenum] will be preserved as an array of images each of which containing a glyph or a rule. N.B. Unicode grapheme cluster is not considered here. 2024/05/24 2.31.1 * fix bugs in outlinetext routine * improve rule treatment in graphictext 2024/05/21 2.31.0 * provide a new metapost operator 'mpliboutlinetext', which mimicks metafun's 'outlinetext'. The syntax is the same as metafun's. (#133) 2024/05/10 2.30.0 * provide a new metapost operator 'mplibglyph', which returns a metapost picture containing outline paths of a glyph in opentype, truetype or type1 fonts. When a type1 font is specified, metapost primitive 'glyph' will be called. In the syntax as follows, subfont number is zero based. mplibglyph 50 of \fontid\font % slot 50 of current font mplibglyph 50 of "cmr10" % type1 font mplibglyph "Q" of "TU/TeXGyrePagella(0)/m/n/10" % font csname mplibglyph "똠" of "NotoSansCJKkr-Regular.otf" % raw filename mplibglyph "Q" of "Times.ttc(2)" % subfont number mplibglyph "똠" of "SourceHanSansK-VF.otf[Regular]" % instance name * provide a new metapost command 'mplibdrawglyph'. In contrast to metapost's 'draw' command, this one fills paths of a picture according to the Nonzero Winding Number Rule. * in 'mplibgraphictext', option 'scale' is deprecated and now a synonym of 'scaled'. In DVI mode, unicode-math package is needed for math formula graphictext. 2024/05/01 2.29.0 * provide new TeX macros to reduce typing toil. \mpfig ... \endmpfig is roughly the abbreviation of \begin{mplibcode}[@mpfig] beginfig(0) token list declared by \everymplib[@mpfig] ... token list declared by \everyendmplib[@mpfig] endfig; \end{mplibcode} \mpfig* ... \endmpfig is roughly the abbreviation of \begin{mplibcode}[@mpfig] ... \end{mplibcode} These macros are protected and unexpandable. In these macros \mpliblegacybehavior{false} is forcibly declared. As both share the same instance name, MetaPost codes are inherited among them. The instance name (default: @mpfig) can be changed by redefining `\mpfiginstancename'. * instance names are allowed in plain TeX as well. The syntax is: \mplibcode[name] ... \endmplibcode \everymplib[name]{ ... } \everyendmplib[name]{ ... } These macros are now protected and unexpandable. * provide new MetaPost operators `mplibtexcolor' and `mplibrgbtexcolor' which convert TeX color expressions to MetaPost color expressions. The latter one forces rgb model results (#112). For instance, mplibtexcolor "olive" % => (0, 0, 1, 0.5) mplibrgbtexcolor "olive" % => (0.5, 0.5, 0) As spot colors are always forced to cmyk or rgb model, it is not recommended to use these operators for them. * write down MetaPost messages into the log file 2024/04/25 2.28.2 * direction of figure box is explicitly declared as TLT (#129) * figure box materials are emitted in one go at the end of the figure (to enable tex.runtoks in spot color shading routine) 2024/04/19 2.28.1 * fix spot color shading routine 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{} 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 * workaround issue #74 relating to PATH limitation * substitute InconsolataN font for Liberation Mono in the manual 2018/04/06 2.12.3 * step copyright year * remove a line relating graphictext hindrance 2018/01/04 2.12.2 * workaround issue #70 "Labels outside beginfig...endfig are not inherited" * 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;' will be inserted after flushing out the mplib figure. * `\mpcolor' command accepts optional argument: for instance, `\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{}. 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{}, 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 * implemented "numbersystem" option. Default value "scaled" can be 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 infont " picture * bypass some ConTeXt commands which raise errors under metafun format * ignore "fontmapfile " 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 2013/09/24 2.01 * fix bug reported by Stephan Hennig: wrong baseline of tex-text box 2013/05/07 2.0 * Update with current ConTeXt code * Adding the possibility of btex...etex commands (Kim) 2011/12/09 1.09 * Fix bug reported by Paul Vojta: spurious spaces. 2011/06/23 1.08 * Fix bug reported by Rolf Dieterich: <, >, TAB anywhere in a luacode 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+). * remove support for using .mem files (to fix the second bug) 2010/10/17 v1.06 * bugfix from Hans (bad function name) 2010/10/10 v1.05 * adapt to luatexbase v0.3 2010/08/02 v1.04 * fixing a bug in LaTeX's detection (made Tikz fail) * setting luamplib-luatex as the default name for the format, it's the case in TeXLive 2010 * adding two test files in the git repository 2010/05/10 v1.03 * adaptation to the new luatexbase package
