MATHASTEXT CHANGE LOG ===================== 1.3v \[2019/09/19\] ---- * LaTeX 2019-10-01 release has made more math macros robust. This applies in particular to the math accents and to the `\hbar`. This required for mathastext to adapt. Also `\leftarrowfill` and `\rightarrowfill` are now defined robust by the kernel, hence mathastext does the same. These changes are dropped if mathastext detects an older LaTeX format. * These LaTeX kernel changes motivated an examination of some redefinitions done (optionally) by mathastext: - The user math alphabet macros got redefined as expanding to some other (robust) math alphabet macros, but were not robust in the strict sense. This does cause some issues for moving arguments in the context of multiple math versions, hence it was a bug. The special behaviour of the math alphabet commands (they redefine themselves and other macros on first use) makes is somewhat problematic for mathastext to keep them updated across math versions and at the same time strictly LaTeX2e robust. Thus mathastext now requires the e-TeX primitive `\protected` and uses it for the definitions of the user level math alphabet macros. - There are a number of `\mathchardef` tokens which (under certain options and/or configuration via the package user interface), mathastext redefines as macros. These macros cause no issue in moving arguments (they are not "fragile"), still it is probably better if they expand only at the time of typesetting. To this effect they are now also `\protected`: `\exists`, `\forall`, `\colon`, `\setminus`, `\mid`, `\prod`, `\sum`, `\imath`, `\jmath`. - The macro `\vert` (which expands to a `\delimiter`) is now defined robust by LaTeX. Its mathastext redefinition is a `\protected` one rather. - The `\{` and `\}` (which get redefined only under `\MTexplicitbracesobeymathxx` regime) are now strictly robust in the LaTeX2e sense (formerly they were `\let` to some robust macros, and this did not make them strictly LaTeX2e-robust entities). * The various changes in mathastext described in the previous item apply independently of the LaTeX release version. The LaTeX format itself requires the e-TeX extensions since 2015. 1.3u \[2019/08/20\] ---- * new feature: the initial release dealt with only one font, and although shortly thereafter the 1.11 version added support for extended math versions, it was documented that some font-dependent set-up (minus as endash, dotless i and j, hbar, math accents) was done only once. This release makes the relevant characters font encoding savvy in each mathastext-extended math version. Thus, they should render correctly even with multiple math versions using fonts with varying encodings. This reinforces importance of using `\MTversion` and not the LaTeX `\mathversion` when switching to a new math version (which got declared via the package interface). The implementation is compatible with Unicode engines and mixed usage of `TU` encoding (OpenType fonts) with traditional 8bits TeX font encodings. For all engines, all used (8bits) encodings must have been passed as options to the `fontenc` package. Thanks to Falk Hanisch for feature request and code suggestions. * new option `unimathaccents`: this adds to option `mathaccents` the demand to use the text font accents for OpenType fonts in math mode via the `\Umathaccent` primitive. Indeed, as my testing showed that this gave non-satisfactory results both with XeTeX and LuaTeX regarding the horizontal placement of the accents, the main option `mathaccents` acts only on 8bits encoded fonts. * bugfix: the `\Mathastext` without optional argument forgot to repeat some font-encoding dependent initialization set-up done originally during package loading. * bugfix: under the `subdued` option macros `\MTmathactiveletters` or `\MTnonlettersobeymathxx` now act like no-ops if issued explicitly while in the `normal` or `bold` math version. Formerly, this was not the case and could cause bugs such as a disappearing minus sign in math mode. * bugfix: the letter `h` used in the `\hbar` obeyed the extra skips as set-up by `\MTsetmathskips`, badly interfering with the horizontal positioning of the bar accent. They are now ignored (as well as the added italic correction). 1.3t \[2018/08/22\] ---- * bugfix: the 1.3s bugfix about `subdued` compatibility with `fontspec` was deficient. * bugfix: very old (v1.2, 2012/12/20) bug causing low-level TeX error during package loading (with pdflatex) when setting up the math minus sign to be the text font endash character, in cases with `\encodingdefault` other than OT1, T1 or LY1, e.g. something like T2A. * `\imath` and `\jmath` obey the `subdued` regime. And the minus sign is now handled especially to ensure perfect compatibility with the `subdued` option. * breaking change: `mathastext` does not redefine anymore `\i` and `\j` to let them be usable both in text and math mode. 1.3s \[2018/08/21\] ---- * fix to an issue with `subdued` option in a `fontspec` context. 1.3r \[2016/11/06\] ---- * documentation tweaks. 1.3q \[2016/10/31\] ---- * new option `unicodeminus`. * the `Recent Changes` section of the documentation has been removed as it was a duplicate of information available in the `Change Log`. * some other changes in the documentation, in particular the use of straight quotes in verbatim. 1.3p \[2016/05/13\] ---- * bugfix: release `1.3n` had forgotten to activate by default its new customization of the amsmath macro `\newmcodes@` (it was done from using `\MTversion` in the document body but not by default at start of body.) * public name `\MTfixmathfonts` for a `1.3o` macro. 1.3o \[2016/05/03\] ---- * `mathastext` fixes an issue related to a feature of `LuaLaTeX` and `luaotfload` that OpenType fonts are declared in one of two modes: `node` and `base`, and only the latter is functional in math mode. But by default text fonts are declared in mode `node`. Thus `mathastext` now intervenes to make it so that the font it declares in math mode will use mode `base`. This fixes issues with for example old style figures being used while the text font used lining figures (or vice versa, depending on the font). But see the code comments for more. 1.3n \[2016/04/22\] ---- * at long last, `mathastext` takes care properly of annoying and perplexing amsmath's `\newmcodes@`. The very recent change in `amsopn.sty` finally made it compatible with Unicode engines, but anyhow, `mathastext` must do its own patch to use the correct font. All of this taking into account the various options passed to the package. Lots of trouble for a tiny thing. 1.3m \[2016/04/02\] ---- * minor code maintenance before annual TL freeze. 1.3l \[2016/01/29\] ---- * compatibility with fontspec's upcoming switch from `EU1/EU2` to `TU` common to both Unicode engines. 1.3k \[2016/01/24\] ---- * typos fixed in the documentation. In particular, the README link to the package homepage had remained broken from day one of the package releases: `mathastext.html` therein was misspelled as `mathsastext.html` ! (but the pdf documentation had the correct link; as well as the CTAN catalogue). 1.3j \[2016/01/15\] ---- * renamed and modified recent `1.3i`'s `\MTactivemathoff` into `\MTeverymathoff`. Added `\MTeverymathdefault`. * `subdued` mode is a bit stronger: also the asterisk reverts to the default (if it was modified due to option `asterisk`), the added extra `\mskip`'s (useful with upright fonts) for `'`, `\exists`, and `\forall` are suppressed rather than re-configured to use `0mu`. Related new commands `\MTexistsdoesskip`, `\MTforalldoesskip`, `\MTprimedoesskip`, `\MTnormalexists`, `\MTnormalforall`, `\MTnormalprime`. * the toggle for using mathematically active letters is only emitted once during package loading; the `\Mathastext` command does not do it anymore; the use in the preamble of `\MTmathstandardletters`, or `\MTnoicinmath` and related commands is not overruled by later use of `\Mathastext`. * quite a few documentation improvements and rewrites, particularly in the description of commands which are related to the modifications of mathcodes (mainly for math activation of characters or letters) as done by mathastext at `\everymath` or `\everydisplay`. 1.3i \[2016/01/06\] ---- * `\url` from `url.sty` as well as `\url` and `\nolinkurl` from `hyperref.sty` use math mode and (by default) the monospace text font. To avoid mathastext overwriting the special preparation done by `{url,hyperref}.sty` the commands `\url/\nolinkurl` are patched to do automatically `\MTactivemathoff` (now `\MTeverymathoff`) before entering math mode. * the extra skips specified by `\MTsetmathskips` are not inserted around letters if inside the arguments of math alphabet commands, or within operator names. * the added explicit italic corrections (for non-oblique fonts) were disabled within math alphabet scopes, except `mathnormal`; they are now disabled within all math alphabets, inclusive of `mathnormal`. 1.3h \[2015/10/31\] ---- * bugfixes: since `1.3d 2014/05/23` the option `symbolgreek` caused `\ell` to become undefined, and, similarly but far worse, options `selfGreek`, `selfGreeks` caused all lowercase Greek letters `\alpha`, `\beta`, etc.. to become undefined. 1.3g \[2015/10/15\] ---- * following `2015/10/01` LaTeX release, removal of the `"luatex"` prefix from the names of the LuaLaTeX math primitives. Compatibility maintained with older LaTeX formats. 1.3f \[2015/09/12\] ---- * the replacement of amsmath's `\resetMathstrut@`, when it is done, emits an Info rather than a Warning as this could be potentially stressful to some users. * the `README` self-extracts from the `dtx` source, as a text file `README.md` with Markdown syntax. 1.3e \[2015/09/10\] ---- * bugfix: under option nosmalldelims, `\lbrace` and `\rbrace` were redefined as math symbols and could not be used as delimiters. 1.3d \[2015/02/26\] ---- * the documentation mentions the improved compatibility of mathastext with the latest (3.34) beamer release: no more need for `\usefonttheme{professionalfonts}`. 1.3d \[2014/05/23\] ---- * new commands `\MTstandardgreek` and `\MTcustomgreek`. * The Greek letters, in case of use of one of the package related options, are left to their defaults in the normal and bold math versions if the subdued option was also used (this was so far the case only with options LGRgreek/LGRgreeks). * `\newmcodes@` of amsmath is left untouched if package lualatex-math is detected. 1.3c \[2013/12/14\] ---- * added a starred variant to `\MTversion` which tells mathastext to only do the math set-up and not modify the text fonts. * added second optional version name argument to `\Mathastext` and to `\MTDeclareVersion`, to transfer settings for things not otherwise changed by mathastext from a math version to the one declared. This is mainly for symbols and large symbols to be the bold ones when the user sets up the series of a mathastextified font to be bold in a mathastext-declared version. * renamed `\defaultprod` to `\MToriginalprod`, `\defaultsum` to `\MToriginalsum`, (this is in case of option symbolmisc). * changes to the dtx organization; options for generating the documentation can be customized in generated mathastext.tex file. * 1.2d code for `\#`, `\$`, `\%`, and `\&` modified erroneously the earlier correct 1.2c code and created a bug showing up with more than 16 math families (a possibility only with lualatex or xelatex). 1.3a \[2013/09/04\] ---- * the somewhat silly `\string`'s are removed from the `\MTsetmathskips` command of release 1.3, thus allowing its first argument to be a macro, or any expandable code, giving a letter. * the amsmath `\resetMathstrut@`, which is incompatible with a mathematically active parenthesis ( is now modified only if necessary (i.e. only when `\MTnonlettersobeymathxx` is issued) and is restored to its original value if not needed anymore (i.e. after `\MTnonlettersdonotobeymathxx`, as for example when switching to the normal version under option subdued). * improved documentation. 1.3 \[2013/09/02\] ---- * commands `\MTsetmathskips` and `\MTunsetmathskips` added. * commands `\MTmathactiveletters` and `\MTmathstandardletters` to govern the math activation of letters independently of its use for insertion of the italic corrections (`\MTicinmath` and `\MTnoicinmath` correspondingly modified). * the new `\luatexUmathcodenum` as available since TL2013 allows identical treatment by mathastext of = and - under both LuaTeX and XeTeX. * `\newmcodes@` of amsmath is left untouched in case of option basic. * a sentence containing | which was written to the log during the loading caused a problem if | was active (typically if `\MakeShortVerb`{\|} was added to the preamble prior to the loading of mathastext). * some preemptive measures taken regarding things such as `\mid`, `\lbrace`, and `\rbrace`, as some packages define these things in manners which made the re-definitions done by mathastext issue errors. 1.2f \[2013/01/21\] ---- * minor code improvements. Change log added to the user manual. 1.2e \[2013/01/10\] ---- This version should be the last one in the 1.2 series as it seems to correct most of the main problems which were introduced with the massive use of mathematically active characters in versions 1.2 and 1.2b. * It is indeed a thorny point when one wants to modify an active character in math mode only (without breaking usage in label's and ref's for example). The package now does that _only_ if the activation originated in the Babel system as it is then possible to modify appropriately the Babel macros `\user@active` and `\normal@char`, at the time of entering math mode (mathastext does all its activation job at `\everymath` and `\everydisplay`). The relevant issues are discussed in section 2.10 of the user manual, in the test file mathastexttestalphabets.tex, and in the source code comments for macro `\mst@mathactivate`. The inherent incompatibility of Babel with packages having made mathematically active the characters itself makes document active is circumvented by this interference of mathastext. A generally applicable Babel patch could be derived from the method used by mathastext. For the non catcode active characters, mathematical activation is used. This is done at the entrance in math mode. * Sadly, the feature of added italic corrections introduced in version 1.2b did not behave as described in the user manual, due to forgotten group braces. Fixed. * The command `\MTlowerast` from the user manual of v1.2d was not the one implemented in the source code. Fixed. * The test files automatically extracted from a latex run on the dtx file have been revised and extended. * The code is better documented. 1.2d \[2013/01/02\] ---- * an incompatibility with amsmath (its macro `\resetMathstrut@`), exists since version 1.2 of the package. This is fixed here. * various improvements in dealing with the asterisk and in the mechanism of letting non-letter symbols obey the math alphabet commands. * documentation extended and improved. 1.2c \[2012/12/31\] ---- * mathastext now inserts automatically after all (latin) letters in math mode their italic corrections, if the font used is upright (sic). This improves the spacings for the positioning of subscripts. The feature is de-activated inside the math alphabets commands (apart from `\mathnormal`), so as to not prohibit the formation of ligatures. * the documentation has been extended to explain in detail the issues which are relevant to the new feature of added italic corrections. * version 1.2 had some bad bugs when confronted to active characters. This is corrected and additionally `\MTnonlettersdonotobeymathxx` is made the default, as the user input is too much constrained in its absence. * a less fatal, but still annoying, typo had made the dot in 1.2 of type `\mathpunct` rather than `\mathord`. * the inner namespace has been rationalized a bit. 1.2 \[2012/12/20\] ---- * a new command sets up the amount of space to be automatically inserted before the derivative glyph (useful when using an upright font). * the scope of the math alphabets has been extended to apply to the non-alphabetical characters, and also to operator names. * the format of the dtx file has changed. The package file is self-extracting from the dtx, and four additional test files are also produced during `latex mathastext.dtx`. 1.15f and 1.15g \[2012/10/25\] ---- * `\$`, `\#`, `\&`, and `\%` had been re-defined by mathastext since its inception in a rather strange (but working) way, which could cause surprises to other packages. Fixed. * the subdued mechanism for the math alphabets is implemented in a simpler and more efficient manner than in 1.15e. * the `defaultxx` options act a bit differently, and are more useful in case of a `too many math alphabets` situation. * various improvements in the documentation. * general clean up and better commenting of the source code. 1.15e \[2012/10/22\] ---- * new user commands to specify skip or glue to be inserted after the math symbols `\exists` and `\forall` * complete (user transparent) rewrite of the code implementing the subdued option; and its action has been extended to apply also to the `\mathbf`, `\mathit`, `\mathsf`, `\mathtt` alphabets and not only to `\mathrm` and `\mathnormal` as in the previous versions. * improvements in the documentation. 1.15d \[2012/10/13\] ---- * the Unicode situation is now correctly treated, throughout the code (this had been left in a half-done way from version 1.14 of April 2011). * this includes an issue related to amsmath and its DeclareMathOperator macro which has been fixed, * and the code related to `\relbar` and `\Relbar` (and `\models`) has been revised. 1.15c \[2012/10/05\] ---- * it is now possible to use distinct fonts in LGR encoding for the Greek letters according to the current math version. * improvements to the documentation. 1.15b ---- * corrected a 'feature' of 1.15 which was backward-incompatible * improvements to the pdf documentation 1.15 \[2012/09/26\] ---- * the subdued option allows the mathastextification to act only locally. * some measures taken to deal with amsmath related issues when using xetex or luatex. 1.14c ---- * a bug is fixed: the `\Mathastext` macro reinitializes the fonts in the normal and bold math versions, but it also erroneously redeclared the math alphabet changing commands which could have been set up in previously defined math versions (via earlier calls to `\Mathastext`\[version_name\]). 1.14b \[2011/04/03\] ---- * there was a bug with `\$`, `\#`, `\&`, `\%` in math mode which showed up when ten or more math families had been declared. This bug affected also the minus sign under the same circumstances, when Unicode engines were used. Fixed. * the options LGRgreek and selfGreek act now a bit differently, and new options LGRgreeks and selfGreeks have been defined. * I also cleaned up a bit the code, for a more structured namespace. 1.14 ---- * mathastext now modifies also the math alphabets `\mathit`, `\mathsf` and `\mathtt`, thus making it a quite generic complete manner to adapt the math configuration to fonts provided with no math support. 1.13b ---- * when the Symbol font is used for `\prod` and `\sum` this will be only for inline math; display math will use the default glyphs 1.13 \[2011/03/11\] ---- * the LGRgreek option is added. * internal changes for better readability of the code. 1.12 ---- * various bugs have been corrected. * the endash and alldelims options are active by default. * the package is more Unicode aware. * the `\Mathastext` command has been improved to facilitate the mechanism of math versions also when using XeTeX or LuaTeX (with package fontspec.) * the en-dash and dotless i and j now work with all encodings, Unicode inclusive. 1.11 \[2011/02/06\] ---- * optional argument to `\Mathastext` macro. 1.1 \[2011/02/01\] ---- * options italic and frenchmath. 1.0 \[2011/01/25\] ---- * Initial version.
