-
-Package hierarchy is needed to examine whether demand importing works
-as expected for "from SUB.PACK.AGE import MODULE".

- When two revision arguments are given, then changes are shown between

- 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.
-
- If there is more than one file being compared and the "child" revision is the
- working directory, any modifications made in the external diff program will be
- copied back to the working directory from the temporary directory.
-
- 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 meld, runs meld (no need to name twice). If
- # the meld executable is not available, the meld tool in [merge-tools]
- # will be used, if available
- 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).

-
- extdiff use external program to diff repository (or selected files)

-Disabled extensions:

- churn extension - command to display statistics about repository history
-
- (use 'hg help extensions' for information on enabling extensions)
-
- $ hg help patchbomb
- patchbomb extension - command to send changesets as (a series of) patch emails
-
- The series is started off with a "[PATCH 0 of N]" introduction, which
- describes the series as a whole.
-
- Each patch email has a Subject line of "[PATCH M of N] ...", using the first
- line of the changeset description as the subject text. The message contains
- two or three body parts:
-
- - The changeset description.
- - [Optional] The result of running diffstat on the patch.
- - The patch itself, as generated by 'hg export'.
-
- Each message refers to the first in the series using the In-Reply-To and
- References headers, so they will show up as a sequence in threaded mail and
- news readers, and in mail archives.
-
- To configure other defaults, add a section like this to your configuration
- file:
-
- [email]
- from = My Name <my at email>
- to = recipient1, recipient2, ...
- cc = cc1, cc2, ...
- bcc = bcc1, bcc2, ...
- reply-to = address1, address2, ...
-
- Use "[patchbomb]" as configuration section name if you need to override global
- "[email]" address settings.
-
- Then you can use the 'hg email' command to mail a series of changesets as a
- patchbomb.
-
- You can also either configure the method option in the email section to be a
- sendmail compatible mailer or fill out the [smtp] section so that the
- patchbomb extension can automatically send patchbombs directly from the
- commandline. See the [email] and [smtp] sections in hgrc(5) for details.
-
- By default, 'hg email' will prompt for a "To" or "CC" header if you do not
- supply one via configuration or the command line. You can override this to
- never prompt by configuring an empty value:
-
- [email]
- cc =
-
- You can control the default inclusion of an introduction message with the
- "patchbomb.intro" configuration option. The configuration is always
- overwritten by command line flags like --intro and --desc:
-
- [patchbomb]
- intro=auto # include introduction message if more than 1 patch (default)
- intro=never # never include an introduction message
- intro=always # always include an introduction message
-
- You can specify a template for flags to be added in subject prefixes. Flags
- specified by --flag option are exported as "{flags}" keyword:
-
- [patchbomb]
- flagtemplate = "{separate(' ',
- ifeq(branch, 'default', '', branch|upper),
- flags)}"
-
- You can set patchbomb to always ask for confirmation by setting
- "patchbomb.confirm" to true.
