repoview: move '_getdynamicblock' next to 'hideablerevs'
There are the two functions that extensions should use to augment the hidding
logic. It seem better to have them together at the top of the file.

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.

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 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). list of commands: extdiff use external program to diff repository (or selected files) (use 'hg help -v -e extdiff' to show built-in aliases and global options) $ echo 'extdiff = !' >> $HGRCPATH Test help topic with same name as extension $ cat > multirevs.py <<EOF > from mercurial import commands, registrar > cmdtable = {} > command = registrar.command(cmdtable) > """multirevs extension > Big multi-line module docstring.""" > @command('multirevs', [], 'ARG', norepo=True) > def multirevs(ui, repo, arg, *args, **opts): > """multirevs command""" > pass > EOF $ echo "multirevs = multirevs.py" >> $HGRCPATH $ hg help multirevs | tail bookmark (this works because the last revision of the revset is used): hg update :@ - Show diff between tags 1.3 and 1.5 (this works because the first and the last revisions of the revset are used): hg diff -r 1.3::1.5 use 'hg help -c multirevs' to see help for the multirevs command $ hg help -c multirevs hg multirevs ARG multirevs command (some details hidden, use --verbose to show complete help) $ hg multirevs hg multirevs: invalid arguments hg multirevs ARG multirevs command (use 'hg multirevs -h' to show more help) [255] $ echo "multirevs = !" >> $HGRCPATH Issue811: Problem loading extensions twice (by site and by user) $ cat <<EOF >> $HGRCPATH > mq = > strip = > hgext.mq = > hgext/mq = > EOF Show extensions: (note that mq force load strip, also checking it's not loaded twice) $ hg debugextensions mq strip For extensions, which name matches one of its commands, help message should ask '-v -e' to get list of built-in aliases along with extension help itself $ mkdir $TESTTMP/d $ cat > $TESTTMP/d/dodo.py <<EOF > """ > This is an awesome 'dodo' extension.

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@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.
