Finding the author of a line of code in Mercurial

Question

How do I find out who is responsible for a specific line of code? I know the linenumber and the filename but I would like Mercurial to tell me the author(s) of that specific lin

Answer 1

I was a fan of "svn blame", so I've added to my ~/.hgrc:

[alias]
blame = annotate --user --number

so I can just type "hg blame" ;-)

Answer 2

On the command-line, you'd want to use hg annotate -u (-u can be combined with -n to get the local revision number, which might come in useful). Check hg help anno for more options.

Answer 3

I looked for this for ages in Tortoise Workbench; thanks to @artemb and @Steve Pitchers for pointing me in the right direction. Still took me a while to spot it.

Answer 4

If you are using TortoiseHG

hgtk annotate <filename>

Or by finding the file in the log, rightclicking it and selecting "Annotate file"

Answer 5

In tortoisehg annotate window, there is a new context menu to enable this.

see https://bitbucket.org/tortoisehg/thg/issues/1861/annotate-window-annotate-with-authors

Answer 6

on the command line , you can use either hg blame or hg annotate.

$ hg blame -u -c -l Filename

-u --user                list the author (long with -v)
-c --changeset           list the changeset
-l --line-number         show line number at the first appearance
