When I run hg commit, Mercurial generates a file for my commit message that looks like this :
HG: Enter commit message. Lines beginning with 'HG:' are removed.
HG: Leave message empty to abort commit.
HG: --
HG: user: Henri Wiechers <[email protected]>
HG: branch 'default'
HG: added a.txt
Is there a way to customize this file? I'd like to include if the working copy has any unknown files.
It's possible to specify this in the [committemplate] config section (see hg help config.committemplate):
"committemplate"
----------------
"changeset"
String: configuration in this section is used as the template to
customize the text shown in the editor when committing.
In addition to pre-defined template keywords, commit log specific one
below can be used for customization:
"extramsg"
String: Extra message (typically 'Leave message empty to abort
commit.'). This may be changed by some commands or extensions.
For example, the template configuration below shows as same text as one
shown by default:
[committemplate]
changeset = {desc}\n\n
HG: Enter commit message. Lines beginning with 'HG:' are removed.
HG: {extramsg}
HG: --
HG: user: {author}\n{ifeq(p2rev, "-1", "",
"HG: branch merge\n")
}HG: branch '{branch}'\n{if(activebookmark,
"HG: bookmark '{activebookmark}'\n") }{subrepos %
"HG: subrepo {subrepo}\n" }{file_adds %
"HG: added {file}\n" }{file_mods %
"HG: changed {file}\n" }{file_dels %
"HG: removed {file}\n" }{if(files, "",
"HG: no files changed\n")}
"diff()"
String: show the diff (see 'hg help templates' for detail)
There's no official way to do it w/o modifying mercurial itself (not terribly intimidating, it's very clean Python), but here's a way to do it by tweaking the editor setting the [ui] section of your ~/.hgrc:
editor = hg status --unknown >! /tmp/unknown_list ; /usr/bin/vim -c "r /tmp/unknown_list"
That is, of course vim on Linux specific, but the same could be done for any decent editor on any OS.
/tmp/unknown_list is not enough. Also, beware of symlink attacks when you write to files in /tmp!
abort: /tmp/unknown_list not under root and a file called "!" is created instead. I've never seen the >! style of redirection, and it doesn't work in sh or bash on my system... was that a typo?editor = /usr/bin/vim -c 'r !hg status --unknown', although for this to be useful in practice, you'd probably want to get fancier and put it at the bottom of the editor with "HG: " at the beginning: editor = /usr/bin/vim -c '$r !hg status --unknown | sed -e"s|^|HG: |"' -c "norm 1G" (the "norm 1G" is to get the cursor back up to the top).I wanted to do this under windows. The idea of customising the editor setting in the ini/.hgrc file made me think of replacing the editor command with a command file.
e.g. if you set this in mercurial.ini:
[ui]
editor = c:\path\to\hgedit.cmd
then hg will call the command file and pass the name of the temp file on the command line. The temp file name can then be accessed in the command file using the %1 parameter.
hgedit.cmd could be something like:
@echo off
hg status --unknown>>%1
notepad %1
If you want to append the output of hg as comments you could do this:
@echo off
echo HG: -->>%1
echo HG: Unknown files:>>%1
for /f "tokens=*" %%a in ('hg st --unknown') do echo HG: %%a>>%1
notepad %1
(You don't have to use notepad of course.)
A Mac/Linux variant of Jim Eggleston's answer... I made a script called hg-commit-editor:
#!/bin/sh
hg status --unknown | sed -e 's|^|HG: |' >> $1
editor $1
and then set it as my commit editor in my hgrc:
[ui]
editor = hg-commit-editor
Use hg commit -m "My message here". You can also set up an editor in your Mercurial.ini or ~/.hgrc file. Add the following:
[ui]
editor = /path/to/your/favorite/editor
There are many ways to do this. Some are even listed on the official wiki. This expands on @Ry4an answer. You can add this to your ~/.hgrc
[ui]
editor = function hgvi { hg status --unknown | sed 's/^/HG: /g' >> "$1"; vi "$1"; }; hgvi
