[PATCH] gnu: maxima: Fix to find info files. |
|
Date: |
Tue, 9 Aug 2022 12:29:42 +0200 |
The Maxima command ‘describe’ allows to pick the relevant portions from
Maxima’s TeXinfo docs. However it does not support reading gzipped info
files.
* gnu/packages/maths.scm (maxima)[arguments]<phases>: Remove
'compress-documentation phase.

Hi Guix,
one of the default phases of the GNU build system is called
'compress-documentation which invokes `gzip' on the .info files but Maxima
does not support gzipped files:

The function bug_report() provides bug reporting information.
(%i1) describe(exp);
Maxima encountered a Lisp error:
The file
#P"/gnu/store/vbhzggawcjp52ww5mx4nc68d7c6s7mwz-maxima-5.45.1/share/info/./maxima\\.info-1"
does not exist:
No such file or directory
Automatically continuing.
To enable the Lisp debugger set *debugger-hook* to nil.
(%i2)
--8<---------------cut here---------------end--------------->8---
This simple fix removes the 'compress-documentation which then causes the
expected results:

(%i1) describe(exp);
-- Function: exp (<x>)
Represents the exponential function. Instances of 'exp (<x>)' in
input are simplified to '%e^<x>'; 'exp' does not appear in
simplified expressions.
'demoivre' if 'true' causes '%e^(a + b %i)' to simplify to '%e^(a
(cos(b) + %i sin(b)))' if 'b' is free of '%i'. See 'demoivre'.
'%emode', when 'true', causes '%e^(%pi %i x)' to be simplified.
See '%emode'.
'%enumer', when 'true' causes '%e' to be replaced by 2.718...
whenever 'numer' is 'true'. See '%enumer'.
(%i1) demoivre;
(%o1) false
(%i2) %e^(a + b*%i);
%i b + a
(%o2) %e
(%i3) demoivre: not demoivre;
(%o3) true
(%i4) %e^(a + b*%i);
a
(%o4) %e (%i sin(b) + cos(b))
There are also some inexact matches for `exp'.
Try `?? exp' to see them.
(%o1) true
(%i2)

Thanks
