# vimparse.pl - Reformats the error messages of the Perl interpreter for use
# with the quickfix mode of Vim
#
# Copyright (� 2001 by J�Ziefle <joerg.ziefle@gmx.de>
# You may use and distribute this software under the same terms as Perl itself.
#
# Usage: put one of the two configurations below in your ~/.vimrc (without the
# description and '# ') and enjoy (be sure to adjust the paths to vimparse.pl
# before):
#
# Program is run interactively with 'perl -w':
#
# set makeprg=$HOME/bin/vimparse.pl\ %\ $*
# set errorformat=%f:%l:%m
#
# Program is only compiled with 'perl -wc':
#
# set makeprg=$HOME/bin/vimparse.pl\ -c\ %\ $*
# set errorformat=%f:%l:%m
#
# Usage:
# vimparse.pl [-c] [-f <errorfile>] <programfile> [programargs]
#
# -c compile only, don't run (perl -wc)
# -f write errors to <errorfile>
#
# Example usages:
# * From the command line:
# vimparse.pl program.pl
#
# vimparse.pl -c -f errorfile program.pl
# Then run vim -q errorfile to edit the errors with Vim.
#
# * From Vim:
# Edit in Vim (and save, if you don't have autowrite on), then
# type ':mak' or ':mak args' (args being the program arguments)
# to error check.
#
# Version history:
# 0.2 (04/12/2001):
# * First public version (sent to Bram)
# * -c command line option for compiling only
# * grammatical fix: 'There was 1 error.'
# * bug fix for multiple arguments
# * more error checks
# * documentation (top of file, &usage)
# * minor code clean ups
# 0.1 (02/02/2001):
# * Initial version
# * Basic functionality
#
# Todo:
# * test on more systems
# * use portable way to determine the location of perl ('use Config')
# * include option that shows perldiag messages for each error
# * allow to pass in program by STDIN
# * more intuitive behaviour if no error is found (show message)
#
# Tested under SunOS 5.7 with Perl 5.6.0. Let me know if it's not working for
# you.

print<<EOT;
Usage:
$0 [-c] [-f <errorfile>] <programfile> [programargs]
-c compile only, don't run (executes 'perl -wc')
-f write errors to <errorfile>
Examples:
* At the command line:
$0 program.pl
Displays output on STDOUT.
$0 -c -f errorfile program.pl
Then run 'vim -q errorfile' to edit the errors with Vim.
* In Vim:
Edit in Vim (and save, if you don't have autowrite on), then
type ':mak' or ':mak args' (args being the program arguments)
to error check.
