remove: properly set return code when warnings are issued
This removes the warn() function in favor of issuing warnings directly
for each kind of file that Mercurial won't remove.
This also uses three separate translatable strings instead of using
string formatting to build the message. This should make it easier to
localize.

'''interpret suffixes to refer to ancestor revisions This extension allows you to use git-style suffixes to refer to the ancestors of a specific revision. For example, if you can refer to a revision as "foo", then:: foo^N = Nth parent of foo foo^0 = foo foo^1 = first parent of foo foo^2 = second parent of foo foo^ = foo^1 foo~N = Nth first grandparent of foo foo~0 = foo foo~1 = foo^1 = foo^ = first parent of foo foo~2 = foo^1^1 = foo^^ = first parent of first parent of foo ''' from mercurial import error def reposetup(ui, repo): if not repo.local(): return class parentrevspecrepo(repo.__class__): def lookup(self, key): try: _super = super(parentrevspecrepo, self) return _super.lookup(key) except error.RepoError: pass circ = key.find('^') tilde = key.find('~') if circ < 0 and tilde < 0: raise elif circ >= 0 and tilde >= 0: end = min(circ, tilde) else: end = max(circ, tilde) cl = self.changelog base = key[:end] try: node = _super.lookup(base) except error.RepoError: # eek - reraise the first error return _super.lookup(key) rev = cl.rev(node) suffix = key[end:] i = 0 while i < len(suffix): # foo^N => Nth parent of foo # foo^0 == foo # foo^1 == foo^ == 1st parent of foo # foo^2 == 2nd parent of foo if suffix[i] == '^': j = i + 1 p = cl.parentrevs(rev) if j < len(suffix) and suffix[j].isdigit(): j += 1 n = int(suffix[i + 1:j]) if n > 2 or n == 2 and p[1] == -1: raise else: n = 1 if n: rev = p[n - 1] i = j # foo~N => Nth first grandparent of foo # foo~0 = foo # foo~1 = foo^1 == foo^ == 1st parent of foo # foo~2 = foo^1^1 == foo^^ == 1st parent of 1st parent of foo elif suffix[i] == '~': j = i + 1 while j < len(suffix) and suffix[j].isdigit(): j += 1 if j == i + 1: raise n = int(suffix[i + 1:j]) for k in xrange(n): rev = cl.parentrevs(rev)[0] i = j else: raise return cl.node(rev) repo.__class__ = parentrevspecrepo
