#
# This script called in a CVS directory compares local files with
# the repository, and prepares an update package containing all
# changes and new files for submission to a CVS maintainer. If there
# are only changes in text files, then a compressed unified diff is
# made (foo.diff.bz2). If there are also changed binary or new files,
# then an archive is made instead (foo.tar.bz2). The base name ("foo")
# can be given as command line argument. Otherwise the directory name
# is used. The script also leaves a diff in uncompressed/unpackaged
# form. This is only for developer convenience -- for a quick check
# of the diff correctness. It is not to be submitted. The script will
# not overwrite any file, but rather rename conflicting files.
#
# Usage: fg-submit [-v] [<basename>]
#
# Options:
# -v ... verbose output
#
# Example:
# $ cd $FG_ROOT/Aircraft/bo105
# $ fg-submit # -> bo105.diff.bz2 or bo105.tar.bz2
#
# $ fg-submit update # -> update.diff.bz2 or update.tar.bz2
#
#
# Spaces in the basename are replaced with "%20". People who prefer
# to have the date in the archive name can conveniently achieve this
# by defining a shell alias in ~/.bashrc:
#
# alias submit='fg-submit "${PWD##*/}-$(date +%Y-%m-%d)"'
#
#
#
# If the script finds an application named "fg-upload", then it calls
# this at the end with two arguments:
#
# $1 ... archive or compressed diff for submission
# $2 ... accessory uncompressed diff, *NOT* for submission!
#
# $1 and $2 are guaranteed not to contain spaces, only $1 is guaranteed
# to actually exist. Such a script can be used to upload the file to an
# ftp-/webserver, and/or to remove one or both files. Example using
# KDE's kfmclient for upload (alternatives: ncftpput, gnomevfs-copy):
#
# $ cat ~/bin/fg-upload
# #!/bin/bash
# echo "uploading $1"
# if kfmclient copy $1 ftp://user:password@server.com; then
# echo "deleting $1 $2"
# rm -f $1 $2
#
# URL=ftp://server.com/$1
#
# # copy URL to KDE's clipboard, so that MMB-clicking pastes it
# dcop klipper klipper setClipboardContents $URL
#
# echo "Done. --> $URL"
# else
# echo "$0: uploading failed!"
# fi
#
#
#
# Whether a file should be included in the archive or not, is decided
# by pattern rules. There is a set of reasonable default rules predefined,
# but alternative settings can be defined in a hidden configuration file
# named ".fg-submit". Such a file is searched in the current directory,
# in its parent directory, in its grand-parent directory and so on,
# and finally in the $HOME directory. The first found file is taken.
#
# A file can use a list of three keywords with arguments, each on a
# separate line:
#
# ALLOW <pattern-list> ... accept & report matching file
# DENY <pattern-list> ... reject & report matching file
# IGNORE <pattern-list> ... silently reject matching file
#
# A <pattern-list> is a space-separated list of shell pattern.
# It may also be empty, in which case it has no effect. Examples:
#
# DENY test.blend
# ALLOW *.xcf *.blend
#
# The list of pattern is checked in the same order in which it was
# built. The first match causes a file to be accepted or rejected.
# Further matches are not considered. Comments using the hash
# character '#' are allowed and ignored.
#
# Some default rules are always added at the end. If you want to
# bypass them, then finish your configuration with an "ALLOW *"
# or "DENY *", and no file will ever reach the default rules.
#
#
# Example:
#
# DENY test.xcf # throw out the test image, but ...
# ALLOW *.xcf # ... allow all other GIMP images (the default
# # rules would otherwise throw them out)
#
# ALLOW not.old # add this file, but ...
# IGNORE *.old # throw out all other "old" files (and don't
# # report that to the terminal)
#
#
# .fg-submit configuration files are "sourced" bash scripts, the
# keywords are simple shell functions. That means that you can
# also use other bash commands in that file, such as "echo", or
# write several commands on one line, separated with semicolon.
# You can even put all special rules in your ~/.fg-submit file,
# with rules depending on the working directory:
#
# case "$PWD" in
# */bo105*) DENY *.osg; ALLOW livery.xcf ;;
# */ufo*) DENY *.tiff ;;
# esac
