Comment (by jhpalmieri):
On my computer, doctesting the file `external.py` causes two windows to
open up, showing the results from `view('2+3')`. Try to find another way
to test whether latex is present and functional, maybe something like
this:
{{{
diff --git a/src/sage/doctest/external.py b/src/sage/doctest/external.py
index f05bc8d..463413a 100644
--- a/src/sage/doctest/external.py
+++ b/src/sage/doctest/external.py
@@ -59,9 +59,14 @@ def has_latex():
sage: has_latex() # random
True
"""
- from sage.misc.latex import view
+ from sage.misc.latex import _run_latex_, _latex_file_
+ from sage.misc.temporary_file import tmp_filename
try:
- view('2+3')
+ f = tmp_filename(ext='.tex')
+ O = open(f, 'w')
+ O.write(_latex_file_('3'))
+ O.close()
+ _run_latex_(f)
return True
except Exception:
return False
}}}
Also, you might consider adding `ImageMagick` (and in particular the
`convert` command) to the set of external programs to be tested.
