Mercurial - how to see the history for a specific line of code

eclipse, mercurial

Solution

The correct answer is `hg grep` (Mercurial grep page).

More deep:

hg grep --all "PATTERN" FILENAME

Sample output:

>hg grep --all "textdomain" functions.php
functions.php:2:-:load_theme_textdomain('fiver', get_template_directory() . '/translation');
functions.php:2:+:load_theme_textdomain('fiver', get_template_directory() . '/languages');
functions.php:1:+:load_theme_textdomain('fiver', get_template_directory() . '/translation');

(in order - filename, revision, action, string in this revision)

Problem

I have a CSS file with thousands of lines of code. I want to see when a specific line/chunk of code was changed, without going back and reviewing each revision that changed this file (that will take a looooong time!) Is there a way, using either TortoiseHg, Eclipse with a Mercurial plugin, or command-line, to view the history of a specific piece of code?
