Lars Mad­sen sub­mit­ted an up­date to the math­tools bun­dle. Ver­sion: math­tools: 1.19 2017-05-24 em­pheq.xml: 2.15 2017-03-31 mh­setup.xml: 1.3 2017-03-31 Li­cense: lp­pl1.3 Sum­mary de­scrip­tion: Math­e­mat­i­cal tools to use with ams­math An­nounce­ment text:
Since the last re­lease (2015) the fol­low­ing is­sues have been ad­dressed: * Changed ams­math re­quire­ment to 2016/11/05 (in or­der to use the aligned fix) * Ap­plied the ams­math aligned fix to mult­lined, now the left part aligned cor­rectly. Re­ported by campa in a note to <https://tex.stack­ex­change.com/a/369212/3929> * Reim­ple­mented `\De­clarePairedDe­lim­iter` and friends to fix the fol­low­ing prob­lem: \math­close{\rvert}^2 vs \math­close\rvert^2 They might not give the same re­sult (de­pend­ing on the font setup). Thus the in­ter­nal wrap­pers need to be changed into three branches: star, nos­tarnon­scaled, nos­tarscaled, where the dif­fer­ence be­tween the last two is whether or not braces are ap­plied to the fences. This prob­lem was re­ported in <https://tex.stack­ex­change.com/q/364308/3929> * Since we were clean­ing up `\De­clarePairedDe­lim­iter` and friends, `\De­clarePairedDe­lim­iterX` is now im­ple­mented as a call to `\De­clarePairedDe­lim­iterXPP` with empty pre- and post­code. * The \De­clarePairedDe­lim­iter(X,XPP) reim­ple­men­ta­tion re­moves a group­ing is­sue re­ported in <https://tex.stack­ex­change.com/q/366665/3929> * Since there is no longer any `nos­tar` wrap­per branch, re­declar­ing the `nos­tar` wrap­per will now give an er­ror. * Re­moved `-\jot` from the mult­lined im­ple­men­ta­tion (in­vis­i­ble line). Is­sue re­ported in at least <http://tex.stack­ex­change.com/a/258162/3929> and <https://tex.stack­ex­change.com/q/369156/3929>. It is not 100% cor­rect, but bet­ter than with `-\jot`. * Fixed bug in em­pheq in re­la­tion to AMS clases * Re­named macros in mh­setup, math­tools and em­pheq such that any xxx_yyy: macro should now con­tain EQ, MH or HT as a pre­fix or in­fix. Thus mak­ing ev­ery­t­ing tru­ely sep­a­rate from ex­pl3 de­fined syn­tax. * Changed \short­in­ter­text such that as long as 'orig­i­nal-in­ter­text=false' (the de­fault), \short­in­ter­text now only work in the same con­text as \in­ter­text * \short­in­ter­text is now also an er­ror in­side the em­pheq con­struc­tion * Spo­radic space fixed in \noe­qref, re­ported by Chris­tian Vet­ter (pri­vate email) * Added \ig­nores­paces af­ter \noin­dent (in­ter­texts), bug in­her­ited from ams­math

math­tools – Math­e­mat­i­cal tools to use with ams­math

Math­tools pro­vides a se­ries of pack­ages de­signed to en­hance the ap­pear­ance of doc­u­ments con­tain­ing a lot of math­e­mat­ics. The main back­bone is ams­math, so those un­fa­mil­iar with this re­quired part of the sys­tem will prob­a­bly not find the pack­ages very use­ful.

Math­tools pro­vides many use­ful tools for math­e­mat­i­cal type­set­ting. It is based on ams­math and fixes var­i­ous de­fi­cien­cies of ams­math and stan­dard . It pro­vides:

  • Ex­ten­si­ble sym­bols, such as brack­ets, ar­rows, har­poons, etc.;
  • Var­i­ous sym­bols such as \coloneqq (:=);
  • Easy cre­ation of new tag forms;
  • Show­ing equa­tion num­bers only for ref­er­enced equa­tions;
  • Ex­ten­si­ble ar­rows, har­poons and hookar­rows;
  • Starred ver­sions of the ams­math ma­trix en­vi­ron­ments for spec­i­fy­ing the col­umn align­ment;
  • More build­ing blocks: mult­lined, cases-like en­vi­ron­ments, new gath­ered en­vi­ron­ments;
  • Maths ver­sions of \make­box, \llap, \rlap etc.;
  • Cramped math styles; and more...

Math­tools re­quires mh­setup.
