Hello,
I have a rather basic RTFM question, but unfortunately
reading the docs and browsing several online tutorials
on this one (for instance at CocoaDevCentral and
borkware) has only left me confused. I have several
shell scripts that I want to run through a Cocoa app.
My program provides support for exporting to several
text formats, and a user has sent me some shell
scripts that will expand the range of possible
formats. Unfortunately, despite being comfortable with
Cocoa, my knowledge of using shell-scripts is rather
poor, so transferring this into a Cocoa app is proving
problematic. I know I need to use NSTask and NSPipe,
but am having difficulties finding the correct way of
doing this for my own script. This is how I would run
my script in terminal:
cat readme.markdown | md2latex.sh > readme.tex
(This just uses a script to convert "readme.markdown"
to a LaTeX file - it uses MultiMarkDown to do so.)
If anyone could give me some pointers on how to get
this working in an NSTask wrapper, I would be _very_
grateful. I have found some basic stuff on getting
using the pipes with NSPipe, but using NSTask along
with "cat" and the ">" output has me baffled.
Sorry if this seems incredibly obvious to many.
Many thanks in advance,
Keith
