`gp-inline`

gp-inline runs Pari/GP tests and checks written inline as comments in document source such as TeX or Perl POD, or even in program code. This can help guard against mistakes of arithmetic etc in a document. GP has various data types and number theory functions allowing quite sophisticated mathematics to be checked alongside the statement of a formula etc.

... so two lots of 7 and three lots of 6 for total 32.
% GP-Test  2*7 + 3*6 == 32

The GP-Test line is a comment so ignored by TeX or similar but gp-inline extracts it and runs it with GP. Various other comment prefixes are recognised too. Read more in the online man page (22k, html).

An accompanying Emacs gp-inline.el can pass tests or defines to a PariEmacs GP sub-process. gp-inline.el in the .deb, .tar.gz, and my ELPA archive. (And see my packaged pariemacs for a .deb of PariEmacs.)
