A while back I told you how to get side-by-side diffs in Mercurial using icdiff. Turns out the author of icdiff has added the
--recursive flag to make the tool accept directories and diff the contents of the files within. New setup instructions follow.
1. Install icdiff
Same as before: Download and install icdiff, making sure
/usr/local/bin is in your
2. Setup Mercurial
Next, lets configure Mercurial so that it knows about
icdiff. We’ll also set the default pager for all commands to
less. Add the following to your
[extensions] extdiff= pager= [extdiff] cmd.icdiff=icdiff # extdiff passes two directories to the diff command # --recursive tells icdiff to treat the two params as directories # and recursively diff their contents. # -- line-numbers shows line numbers on both sides opts.icdiff=--recursive --line-numbers [pager] # Setting the variable LESS is like passing those options to less. # In this case, -F (quit if fits on screen), and -R (pass through control chars, # required for color output) pager = LESS='FR' less # Use pager for these commands only. Add any commands you use here. attend = icdiff,diff,status,log
You can now replace
diff in your Mercurial commands with
icdiff, and it will do a side-by-side diff instead of inline.
3. Aliases (optional)
hg icdiff is of course too long, add the following aliases to your
# side-by-side diffs for uncommitted files alias ic='hg icdiff' # diff all changes since the base revision, including uncommitted # (from master if you are using bookmarks, for example) alias ica='hg icdiff -r .^' # diff the existing changes, excluding uncommitted alias ice='hg icdiff --ch .'
