Discard all and get clean copy of latest revision?

Those steps should be able to be shortened down to:

hg pull
hg update -r MY_BRANCH -C

The -C flag tells the update command to discard all local changes before updating.

However, this might still leave untracked files in your repository. It sounds like you want to get rid of those as well, so I would use the purge extension for that:

hg pull
hg update -r MY_BRANCH -C
hg purge

In any case, there is no single one command you can ask Mercurial to perform that will do everything you want here, except if you change the process to that "full clone" method that you say you can't do.


To delete untracked on *nix without the purge extension you can use

hg pull
hg update -r MY_BRANCH -C
hg status -un|xargs rm

Which is using

update -r --rev REV revision

update -C --clean discard uncommitted changes (no backup)

status -u --unknown show only unknown (not tracked) files

status -n --no-status hide status prefix


If you're looking for a method that's easy, then you might want to try this.

I for myself can hardly remember commandlines for all of my tools, so I tend to do it using the UI:


1. First, select "commit"

Commit

2. Then, display ignored files. If you have uncommitted changes, hide them.

Show ignored files

3. Now, select all of them and click "Delete Unversioned".

Delete them

Done. It's a procedure that is far easier to remember than commandline stuff.


hg up -C

This will remove all the changes and update to the latest head in the current branch.

And you can turn on purge extension to be able to remove all unversioned files too.
