google-edit

#!/bin/bash

# This script deals with the weirdness of how googlecl downloads txt format documents from
# google.  Theres some weird header bytes on the file it gets and my emacs has no idea how
# to preserve the newline form, so we transform before sending to emacs.  Your mileage may vary.
#
# You can invoke this script like this:
#
# $ google docs edit --editor google-edit --format txt --title yourtitlehere
#
# I use an alias called doc
#
# alias doc="google docs edit --editor google-edit --format txt --title"
#
# Pretty handy-- even creates the document if it doesn't exist.

# perhaps you would prefer vim?

cp $* $*.orig_download

# chomp the first 3 characters off the file
ruby -e 'f=ARGV[0];c=File.read(f)[3..-1];File.open(f,"w"){|h|h.print(c)}' $*

# clean up newlines

# make a reference copy of the transformed file
cp $* $*.orig_transform

# open up the editor and edit the file
