View diff of each files (in vertial split) in gvim/vim diff mode. And, to store the diff of each files in .diff.html extension Note: Color scheme of the html file is based on your colorscheme in .vimrc file.

To navigate in diff mode in vim:

• do - Get changes from other window into the current window.
• dp - Put the changes from current window into the other window.
• ]c - Jump to the next change.
• [c - Jump to the previous change.

Without using diff command from terminal:

• In vim, load files via either vertical (:vs) or horizontal (:sp) split
• :diffthis to diff files from this window of files in the split.
• :diffoff to turn off diff mode.

In terminal:

 /usr/local/bin/vim -d $1 $2 -c ":TOhtml" -c ":saveas! $(basename $2).diff.html" -c ":qall!"

• $1 (or ${6} in SVN) is WAS file.
• SVN WAS FILE FORMAT [folder]/.svn/text-base/[file].svn-base
• $2 is IS file.

To put in your alias file:

hdiff() {
     /usr/local/bin/vim -d $1 $2 \
      -c ":TOhtml" \
      -c ":saveas! $(basename $2).diff.html" \
      -c ":qall!"; 
}

Note: "\" is the end of line

or put it in one line:

   hdiff() {  /usr/local/bin/vim -d $1 $2 -c ":TOhtml" -c ":saveas! $(basename $2).diff.html" -c ":qall!"; }

File: svn_gvimdiff
