Summary description: Mathematical sets with correctly scaled braces and separator
Announcement text:
setbuilder is a new package providing smart set-builder notation: \set{x \given x > 0} typesets the braces and the separator bar with correct spacing, offers automatic (\set*) and fixed (\set[\Big]) scaling of both braces and separator, a "colon" style option, and a synonym= option for name-conflict-free usage.
The package’s Catalogue entry can be viewed at https://ctan.org/pkg/setbuilder The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/setbuilder/
Thanks for the upload. For the CTAN Team Petra Rübe-Pugliese

setbuilder – Mathematical sets with correctly scaled braces and separator
The package provides a \set command for set-builder notation: \set{x \in \mathbb{R} \given x^2 < 2}. The separator (a vertical bar, or a colon with the colon option) is typeset with correct thin spaces, which automatically vanish in sub- and superscripts. The starred form \set* scales the braces and the separator together; \set[\Big] sets a fixed size. A synonym=<name> package option defines the same command under a different name, e.g. when \set is already taken by another package. The package is based on mathtools.
