[FILE]... use external program to diff repository (or selected files) Show differences between revisions for the specified files, using an external program. The default program used is diff, with default options "-Npru". To select a different program, use the -p/--program option. The program will be passed the names of two directories to compare. To pass additional options to the program, use -o/--option. These will be passed before the names of the directories to compare. When two revision arguments are given, then changes are shown between those revisions. If only one revision is specified then that revision is compared to the working directory, and, when no revisions are specified, the working directory files are compared to its parent. use "hg help -e extdiff" to show help for the extdiff extension options: -p --program CMD comparison program to run -o --option OPT [+] pass option to comparison program -r --rev REV [+] revision -c --change REV change made by revision -I --include PATTERN [+] include names matching the given patterns -X --exclude PATTERN [+] exclude names matching the given patterns [+] marked option can be specified multiple times use "hg -v help extdiff" to show the global options $ hg help --extension extdiff extdiff extension - command to allow external programs to compare revisions The extdiff Mercurial extension allows you to use external programs to compare revisions, or revision with working directory. The external diff programs are called with a configurable set of options and two non-option arguments: paths to directories containing snapshots of files to compare. The extdiff extension also allows you to configure new diff commands, so you do not need to type "hg extdiff -p kdiff3" always. [extdiff] # add new command that runs GNU diff(1) in 'context diff' mode cdiff = gdiff -Nprc5 ## or the old way: #cmd.cdiff = gdiff #opts.cdiff = -Nprc5 # add new command called vdiff, runs kdiff3 vdiff = kdiff3 # add new command called meld, runs meld (no need to name twice) meld = # add new command called vimdiff, runs gvimdiff with DirDiff plugin # (see http://www.vim.org/scripts/script.php?script_id=102) Non # English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in # your .vimrc vimdiff = gvim -f "+next" \ "+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))" Tool arguments can include variables that are expanded at runtime: $parent1, $plabel1 - filename, descriptive label of first parent $child, $clabel - filename, descriptive label of child revision $parent2, $plabel2 - filename, descriptive label of second parent $root - repository root $parent is an alias for $parent1. The extdiff extension will look in your [diff-tools] and [merge-tools] sections for diff tool arguments, when none are specified in [extdiff]. [extdiff] kdiff3 = [diff-tools] kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child You can use -I/-X and list of file or directory names like normal "hg diff" command. The extdiff extension makes snapshots of only needed files, so running the external diff program will actually be pretty fast (at least faster than having to compare the entire tree). list of commands: extdiff use external program to diff repository (or selected files) use "hg -v help extdiff" to show builtin aliases and global options $ echo 'extdiff = !' >> $HGRCPATH Test help topic with same name as extension $ cat > multirevs.py <<EOF > from mercurial import commands > """multirevs extension > Big multi-line module docstring.""" > def multirevs(ui, repo, arg, *args, **opts): > """multirevs command""" > pass > cmdtable = { > "multirevs": (multirevs, [], 'ARG') > } > commands.norepo += ' multirevs' > EOF $ echo "multirevs = multirevs.py" >> $HGRCPATH $ hg help multirevs Specifying Multiple Revisions When Mercurial accepts more than one revision, they may be specified individually, or provided as a topologically continuous range, separated by the ":" character. The syntax of range notation is [BEGIN]:[END], where BEGIN and END are revision identifiers. Both BEGIN and END are optional. If BEGIN is not specified, it defaults to revision number 0. If END is not specified, it defaults to the tip. The range ":" thus means "all revisions". If BEGIN is greater than END, revisions are treated in reverse order. A range acts as a closed interval. This means that a range of 3:5 gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6. use "hg help -c multirevs" to see help for the multirevs command $ hg help -c multirevs hg multirevs ARG multirevs command use "hg -v help multirevs" to show the global options $ hg multirevs hg multirevs: invalid arguments hg multirevs ARG multirevs command use "hg help multirevs" to show the full help text [255] $ echo "multirevs = !" >> $HGRCPATH Issue811: Problem loading extensions twice (by site and by user) $ debugpath=`pwd`/debugissue811.py $ cat > debugissue811.py <<EOF > '''show all loaded extensions > ''' > from mercurial import extensions, commands > > def debugextensions(ui): > "yet another debug command" > ui.write("%s\n" % '\n'.join([x for x, y in extensions.extensions()])) > > cmdtable = {"debugextensions": (debugextensions, (), "hg debugextensions")} > commands.norepo += " debugextensions" > EOF $ echo "debugissue811 = $debugpath" >> $HGRCPATH $ echo "mq=" >> $HGRCPATH $ echo "hgext.mq=" >> $HGRCPATH $ echo "hgext/mq=" >> $HGRCPATH Show extensions: $ hg debugextensions debugissue811 mq Disabled extension commands: $ HGRCPATH= $ export HGRCPATH $ hg help email 'email' is provided by the following extension: patchbomb command to send changesets as (a series of) patch emails use "hg help extensions" for information on enabling extensions $ hg qdel hg: unknown command 'qdel' 'qdelete' is provided by the following extension: mq manage a stack of patches use "hg help extensions" for information on enabling extensions [255] $ hg churn hg: unknown command 'churn' 'churn' is provided by the following extension: churn command to display statistics about repository history use "hg help extensions" for information on enabling extensions [255] Disabled extensions: $ hg help churn churn extension -
