[pmwiki-users] New Recipe: WikiSh

[Peter & Melodye Bowers]

I've just put a very-alpha recipe out there called WikiSh.  It's working in
the test cases I've thrown at it, but no doubt there is significant testing
remaining -- please let me know when you run into problems with it.

It was started at the same time as Text Extract, but with a different
purpose and direction in implementation.  However, initial code and etc. all
come from Hans...

The problem below (returning lines from one text pattern to another) would
be handled in this manner:

{(sed -n '/TextPatternA/,/TextPatternB/p' file)}

You can also specify other commands to the sed command using multiple
applications of the -e option as follows:

{(sed -n -e '1,2p' -e '/TextPatternA/,/TextPatternB/p' -e
's/searchfor/replace/g' file)}

(This would return the first 2 lines and the lines between TextPatternA and
TextPatternB (inclusive) and also do a search/replace.)

The other commands contained within WikiSh include wc (-w=wordcount which
also does -l=linecount and -c=charcount), head (returns the top -n=n lines
from a file), tail (same for the end of the file), cat (returns all lines),
etc.

This is a beginning - lots more to go, but I thought since it answered this
specific need here it might be appropriate to put it out there...
