I'm trying to do something which (I think) is very simple: I just want to run a
line of text through Markdown and get the output.
I've spent all day reading through the code for OSProcess and CommandShell. It
took me a while, but I finally figured out I can run a command and get its
output with:
UnixProcess waitForCommandOutput: 'ls ~'
The next problem I'm having is getting markdown to run on an arbitrary string.
If I go into my shell and do:
$ /usr/local/bin/markdown <<END
> # This is a heading
> This is a paragraph with _emphasis_
> END
<h1>This is a heading</h1>
Then I get the output that I expect:
<p>This is a paragraph with <em>emphasis</em></p>
I can't figure out how to do this with OSProcess though. I've tried:
UnixProcess waitForCommand: ('/usr/local/bin/markdown <<END
hello world
END')
but with no luck. I've also tried using OSProcess at a lower level, setting up
the stream input object, but it seems to require a reference to an actual file,
rather than just a stream.
Anyone have any ideas? I want to take an arbitrary string and use that as the
input to my markdown command, and then store that output in an instance
variable. I could use some help.
Thanks,
Pat
