Developer Basics
This page has some basic code examples to get you started hacking on hg. See also MercurialApi.
Looking at changesets
Here's some simple code to look at a changeset:
1 from mercurial import ui, hg
2
3 u = ui.ui() # get a ui object
4 r = hg.repository(u, ".") # get a repo object for the current directory
5 c = r.changectx("tip") # get a context object for the "tip" revision
6
7 # show some information about the changeset
8 print c # represented as the changeset hash
9 print c.user()
10 print c.description()
11 print
12
13 # let's take a peek at the files
14 files = c.files()
15 for f in files:
16 fc = c[f]
17 print " ", f, len(fc.data())
And the output looks like this:
