How to get the "dirty plus" with hg log --template? - mercurial

hg log -l1 -r . --template {node}
Will give you the full changeset hash for your current working directory, but how do I get the + on the end to indicate that your copy is dirty (uncomitted changes) like hg id does?

Use hg id -i; if you want the full hash, add --debug. (hg log does not examine the work-tree and hence has no idea whether it's dirty.)

How can I view the remaining changesets left to check in an hg bisect?

When I'm running hg bisect, sometimes I want to "look ahead" at what's remaining, to see if there are any obvious culprits I could check while a fairly slow bisection test runs.
So given I've run
> hg bisect -g
Testing changeset 15802:446defa0e64a (8 changesets remaining, ~2 tests)
How can I view which 8 changesets are remaining?
You can use the bisect("untested") revset to view the untested changesets. E.g.:
hg log -r 'bisect(untested)'
If that is too much information, you can also combine it with a template option:
hg log -r 'bisect(untested)' -T '{rev}\n'
Or you can just restrict the output to the first and last entry of the range:
hg log -r 'first(bisect(untested))+last(bisect(untested))'
You can also create revset aliases in your .hg/hgrc or ~/.hgrc file to save some typing, e.g.:
[revsetalias]
tbt = bisect("untested")
tbt2 = first(tbt)+last(tbt)
Then you can do (for example):
hg log -r tbt
Note that if you call a revset alias untested, you'll have to quote the string untested (e.g. bisect("untested")), hence my choice of tbt (for "to be tested").
See hg help revsets for more revsets pertaining to bisection.

Mercurial list files from changegroup

I want a simple command to get the list of files which differ after pushing to a mercurial repository on a server,
that is the differences between the previous push and the current push.
On the server, I have a hook on the changegroup event which calls a bash script.
$HG_NODE is the revision for the first commit in the changegroup.
My attempts:
hg status --rev $HG_NODE::
Exclude changes made in the first commit
hg status --rev $HG_NODE^1::
Includes changes that affected the parent revision through others pushes.
hg log -v --rev $HG_NODE:: | grep ^files
Include committed then reverted changes, still has 'files:' and files are not one per line
hg status --rev $HG_NODE:: && hg status change --rev $HG_NODE
Does not give exactly what I want, rather the change between the parent to the first commit in the changegroup + the change between this one (instead of the two changesets merged)
hg status --rev some_tag ; hg tag --remove some_tag ; hg tag --local some_tag
(Have not tried, is it a good idea?) Uses a local tag to keep track of the head for the last push, updates it each time.
Also I want to only monitor the default branch, so I assume I will use something like --rev "revision and branch(default)" or the branch option for hg log.
As to why, I need to go through the changes to determine parameters for an automated build.
hg stat -r is to list the removed files. To get the list of files which differ, you should use hg st --rev as follows.
hg st -m --rev tip^:tip

Mercurial reporting - Revision and file change report available?

I'm looking for a way to view all of a repository's branches and each file that has changed in that branch. I'm not interested in the file level changes as this report is for simple auditing.
Can this be done?
hg log -b <branchname> --template "{files} "
Plus some post-processing, because output will be like this
lang/UTF-8/serendipity_lang_ru.inc.php lang/UTF-8/serendipity_lang_ru.inc.php lang/UTF-8/serendipity_lang_ru.inc.php lang/UTF-8/serendipity_lang_ru.inc.php plugins/serendipity_event_assigncategories/UTF-8/lang_ru.inc.php plugins/serendipity_event_entryproperties/UTF-8/lang_ru.inc.php plugins/serendipity_event_freetag/UTF-8/lang_ru.inc.php plugins/serendipity_event_gravatar/UTF-8/lang_ru.inc.php plugins/serendipity_event_relatedlinks/UTF-8/lang_ru.inc.php plugins/serendipity_event_nl2br/UTF-8/lang_ru.inc.php plugins/serendipity_event_freetag/UTF-8/lang_ru.inc.php
Use hg status to get information about files that have changed between revisions. See the revset language for how to select the revisions.
If you want to see file changes between the first and last changesets on branch B:
$ hg status --rev "min(branch(B)):max(branch(B))"
You can even make an alias for this:
[alias]
audit = status --rev "min(branch($1)):max(branch($1))"
and then use hg audit B to get the same result.

In Mercurial (hg), how do you see a list of files that will be pushed if an "hg push" is issued?

We can see all the changesets and the files involved using
hg outgoing -v
but the filenames are all scattered in the list of changesets.
Is there a way to just see a list of all the files that will go out if hg push is issued?
First, create a file with this content:
changeset = "{files}"
file = "{file}\n"
Let's say you call it out-style.txt and put it in your home directory. Then you can give this command:
hg -q outgoing --style ~/out-style.txt | sort -u
A somewhat under-appreciated feature: hg status can show information about changes in file status between arbitrary changesets. This can be used to get a list of files changed between revisions X and Y:
hg status --rev X:Y
In this case, we can use hg outgoing, to find the first outgoing changeset X and then do
hg status --rev X:
to see the files changes since revision X. You can combine this into a single line in your shell:
hg status --rev $(hg outgoing -q --template '{node}' -l 1):
I usually use
hg outgoing -v | grep files
It makes the listing shorter, but doesnt sort. But thus far I havent been in a situation where I want to push so much (and at the same time check the files) that its been a problem.
[Edit]
To do what you want:
Use cut to remove the files: part
For changesets with more than one touched file, use tr to put them on separate lines
Finally sort the resulting output with sort
Like so:
hg outgoing -v |grep files: |cut -c 14- |tr ' ' '\n' |sort -u
You can put this in ~/outgoingfiles.sh or something to have it nice and ready.
I use Torgoise Hg, which is a shell extension that has a "synchronize" view allowing you to see outgoing files before you push them. It's convenient for commits as well, and other things.
A simple hg out will also solve this.
It will list all committed but yet to push checkins.

How do I get the current mercurial revision without calling hg?

In Git the current revision hash is stored in
.git/refs/heads/master
Is there an equivalent in Mercurial that doesn't require me making a call to hg log -l1? I know I can get the current branch in .hg/branch.
This is to "display" the current hg hash on screen when browsing a web page.
$ hg parents --template="{node}\n"
52b8cee1e59c91b9147635b7f44a3a8896ee0b00
$ hexdump -n 20 -e '1/1 "%02x"' .hg/dirstate
52b8cee1e59c91b9147635b7f44a3a8896ee0b00
But why can't you just call hg parents --template="{node}\n"?
hg id --debug -i -r .
I'm not a mercurial expert, but taking the sledgehammer approach and doing a grep for the current revision hash in .hg yields only one possible, and that is .hg/branchheads.cache.
I believe this caches all the heads of the repository, so it may have multiple entries. By default, I think it will always have two entries, one for the default branch and one for the tip revision number.
I think that branchheads.cache is rebuilt whenever new changesets arrive, so it should always have the correct current revision hash in it.
