Lars Mad­sen sub­mit­ted an up­date to the in­ter­val pack­age. Ver­sion: 0.4 2019-03-06 Li­cense: lp­pl1.3 Sum­mary de­scrip­tion: For­mat math­e­mat­i­cal in­ter­vals, en­sur­ing proper spac­ing An­nounce­ment text:
New in ver­sion 0.4: Added \oin­t­er­val, \lin­ter­val, \rin­ter­val short hands (sug­gested by Frank Mit­tel­bach). They are just short ways to say, say, \in­ter­val[open]{a}{b}, etc. Re­moved \in­ter­valsetup (now gives an er­ror if used, was set to equal \in­ter­val­con­fig)
The pack­age’s Cat­a­logue en­try can be viewed at https://ctan.org/pkg/in­ter­val The pack­age’s files them­selves can be in­spected at http://mir­ror.ctan.org/macros/la­tex/con­trib/in­ter­val/

## in­ter­val – For­mat math­e­mat­i­cal in­ter­vals, en­sur­ing proper spac­ing

When typ­ing an open in­ter­val as $]a,b[$, a clos­ing bracket is be­ing used in place of an open­ing fence and vice versa. This leads to the wrong spac­ing in, say, $]-a,b[$ or $A\in]a,b[=B$. The pack­age at­tempts to solve this us­ing:
\in­ter­val{a}{b} -> [a,b]
\in­ter­val[open]{a}{b} -> ]a,b[
\in­ter­val[open left]{a}{b} -> ]a,b]

The pack­age also sup­ports fence scal­ing and en­sures that the en­clos­ing fences will end up hav­ing the proper clos­ing and open­ing types. maths does not do this job prop­erly.

The pack­age de­pends on pgfkeys.
