I'm a bit confused, I've been through the docs and I cannot quite get a handle
on how to accomplish this.
I want to create a macro that sends the buffer contents to a shell command and
then have the macro parse the results from the shell command. I do not wish
to have the output of the shell command be echoed back to the current buffer.
I do not care if I have to use another temporary buffer to work in, but I am
confused on how do I get the contents of the buffer? I have written a few
modes, a few simple macros (search/replace) but have never had to get the
buffer contents or work with external commands.
What this macro does is check's the syntax of a python file live. It's an idea
I got from a NEdit macro that I stumbled across, A simple syntaxCheck.py file
sends the contents passed to it to the python compile() command, compile will
return any errors or nothing if no errors occurred.
I will then parse the results of the errors (which I control the output of via
the syntaxCheck.py file) and hopefully hilight any errors that syntaxCheck.py
finds with my current python buffer.
syntaxCheck.py is very simple:
import sys, os
f = "%s\n" % "".join(sys.stdin) # file without ending \n otherwise pukes
compile(f, "", "exec")
except Exception, e:
print "%s\n%d\n%d\n%s\n" % (e.msg, e.lineno, e.offset, e.text)
I want to work with the buffer so I don't have to save all the time to do a
check, and then have to read in syntaxCheck.py the file, etc... Seems a lot
simpler to just pass buffer contents.
Thanks for any help!
