Mercurial API ctx.files() doesn't work in merge

[nemo]

Hi

I want to display all the changed files and their status in a changeset,
like this

for f in ctx.files():
for p in ctx.parents():
status = f not in p and 'added'
status = status or (f in ctx and 'modified' or 'removed')
files.append({'status': status, 'node': node, 'filename': f,})

But it seems doesn't work for merge changeset, ctx.files() returns empty
list when ctx is a merge changset.

How can I display the changed files for merge changeset ?

Thanks

It works correctly, it just doesn't meet your expectations. Please read
the help for 'hg diff', 'hg status', and 'hg log -p' a few times each to
be enlightened regarding merges.
