Mercurial log with one-liners
Solution 1
hg log --style compact
You can also use templates to display log out in different formats
hg help templates
In your case if you want to display only node ids do something like this
hg log --template "{node}\n"
Solution 2
You can use hg log
with a --template option, e.g.:
hg log --template '{node|short} | {date|isodatesec} | {author|user}: {desc|strip|firstline}\n'
This should show something like this (example from the GNU Emacs trunk I converted locally to an hg repository):
$ hg log --limit 5 --template '{node|short} | {date|isodatesec} | {author|user}: {desc|strip|firstline}\n'

Once you have a nice template for one-line summaries of changesets, you can add a command alias in your ~/.hgrc
file like this:
[alias]
shortlog = log --template '{node|short} | {date|isodatesec} | {author|user}: {desc|strip|firstline}\n'
With the alias installed you can now type hg shortlog
, hg short
or even hg shor
(to uniquely identify hg shortlog
instead of hg showconfig
) and all the usual `log' command-options. For instance it should now be possible to type:
$ hg short -r 100:103
db9f8efcf689 | 1990-09-14 19:07:14 +0000 | jimb: *** empty log message ***
5874bf15e07d | 1990-09-19 18:22:41 +0000 | gnulists: Initial revision

b2656b7830e4 | 1990-10-09 02:52:33 +0000 | rms: *** empty log message ***
$
or even things that use tag names (example from the mercurial crew repository itself):
keramida@kobe:/hg/mercurial/crew$ hg short -r 1.4 -r 1.5 -r 1.6
31ec469f9b55 | 2009-11-16 21:25:36 +0100 | mg: i18n-ja: fixed bad indentation

f786fc4b8764 | 2010-06-29 12:12:34 +0200 | mads: log: follow filenames through renames (issue647)
keramida@kobe:/hg/mercurial/crew$
Solution 3
To get the description on one line even if original comment contains multiple line combine a splitlines and join function like below:
{join(splitlines(desc), ' ')}
Here is an example i'm using to extract data as CSV:
hg log --template "{node};{date|shortdate};{branch};{author};{join(splitlines(desc), ' ')};{diffstat};files: {join(files, ', ')}\n"

The regular
hg log
command gives output with at least 4 lines per changeset. For examplechangeset: 238:03a214f2a1cf user: My Name <[email protected]> date: Thu Aug 26 09:49:32 2010 +0200 summary: Added tag v1.1 for changeset f22fd3974361
I mean to remember that there was a command to print a log in a more compact way what just had one line per changeset. A format that you could basically stick in a changelog.txt file and it would look nice.
Does that exist? Or am I mixing this with something I have seen with git or something else?
