Description (last modified by William Stein)

To: "Kyle Schalm" <>,
Subject: Re: [SAGEdev] long string parsing bug in

The SAGE pre-parser currently works on single lines only -- it doesn't
take into account multi-line blocks.  This is more a
not-implemented-error than a bug.  Many thanks for sending this email
though, since it's an excellent test case:
load with
sage: load "/Users/kyle/Documents/math/scripts/mm.sage"

I can't find this mm.sage example any more. Moreover, the preparser does work on multiple lines, so won't fix until get a proper bug report.

I found that loading files with triple quoted multiline strings would break. Now fixed:

Finally fixed multiline preparser issue for command line.
