# 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.

|
* 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.
