this helps users to know what kind of option is:
- no value is required(flag option)
- value is required
- value is required, and multiple occurrences are allowed
each kinds are shown as below:
-f --force force push
-e --ssh CMD specify ssh command to use
-b --branch BRANCH [+] a specific branch you would like to push
if one or more 3rd type options are shown, explanation for '[+]' mark
is also shown as footnote.
The docstring is translated twice: once when used as a format string,
and once on display. The second translation fails when the first
translation introduces non-ASCII characters in the string.
The problem is that the gettext module calls unicode(message) on the
string, i.e., it decodes it to a Unicode string using the ASCII
encoding (the default encoding). By translating it into a Unicode
string here, the unicode() call becomes a noop.
This adds 3-way diff for merge changesets (using -c) and for diffing
the working directory context against two parents. To enable it, use
the new magic value '$parent2' in the argument line. In order to work,
your differ must support that the second parent argument is left out;
this will happen in 2-way mode. Default arguments are as before, without
enabling 3-way mode, ensuring backwards compatibility.
This also fixes a problem when diffing a merge changeset with a single
file change. Extdiff would sometimes do the wrong thing in that situation.
In addition to the old cmd.foo, opts.foo hgrc entries, allow a more simple
alias = command [opts]... form. For example:
[extdiff]
cdiff = colordiff -uprN
Extdiff was always making a temporary directory and copying files even when not required. This change makes extdiff avoid the copy when diffing a single file that lives in the wc. This lets external diff tools edit the working copy file directly. It also lets other extensions resuse the functions in extdiff and get in-place diffs.
Made the status info only display in verbose mode since most hg commands aren't so chatty. This also makes it cleaner for other extensions to call extdiff.
- files that comes from a different branch are marked as modified
but aren't present in the original manifest
- add a testcase for extdiff and for regular diff
* Capitalize the first letter of all sentences
* Add an example for GNU diff(1) 'context diff' mode.
* Explain the requirement for separate cmd.xxx and opts.xxx
options in .hgrc, which hopefully will guard against users
trying to add:
[extdiff]
# Add a new Mercurial command called `cdiff', which calls
# GNU diff(1) in 'context diff' mode.
cmd.cdiff = diff -Nprc5
which fails for recent crew builds with:
$ hg cdiff .
making snapshot of 1 files from rev 07dc4a569f4e
making snapshot of 1 files from working dir
diff -Nprc5: not found
The correct way to do this is by separating the cmd.cdiff and
opts.cdiff parts like this:
[extdiff]
# Add a new Mercurial command called `cdiff', which calls
# GNU diff(1) in 'context diff' mode.
cmd.cdiff = diff
opts.cdiff = -Nprc5
so add it as a new example and explicitly describe it in the
extdiff comments.
