Since SList's are now much more common (due to a = !syscmd, mglob etc
returning them) I added a nifty little utility to SList: grep.
Here's how it works:
[~/ipython]|15> a = !cat README
['Please see the doc/ directory for full manuals and other documents.
The manual is',
[~/ipython]|19> ;a.grep install
<19> SList (.p, .n, .l, .s, .grep available). Value:
0: These manuals normally get installed to
$PREFIX/share/doc/ipython-VERSION, unless you
1: redirect the installer via a --prefix/--home option. Normally, $PREFIX is
2: /usr, but your Python may be installed elsewhere. You can see its value by
[~/ipython]|20> _.grep('prefix', prune = 1)
<20> SList (.p, .n, .l, .s, .grep available). Value:
0: /usr, but your Python may be installed elsewhere. You can see its value by
[~/ipython]|21> svn diff
I suppose the usefullness of this for file list / text data
manipulation is obvious. No more need to do those list comprehensions.
It's late in the release cycle, but very useful for tons of common problems.
