'''Mercurial interface to codereview.appspot.com.
To configure, set the following options in
your repository's .hg/hgrc file.
[extensions]
codereview = /path/to/codereview.py
[codereview]
server = codereview.appspot.com
The server should be running Rietveld; see http://code.google.com/p/rietveld/.
In addition to the new commands, this extension introduces
the file pattern syntax @nnnnnn, where nnnnnn is a change list
number, to mean the files included in that change list, which
must be associated with the current client.
For example, if change 123456 contains the files x.go and y.go,
"hg diff @123456" is equivalent to"hg diff x.go y.go".

# RE: UNICODE STRING HANDLING
#
# Python distinguishes between the str (string of bytes)
# and unicode (string of code points) types. Most operations
# work on either one just fine, but some (like regexp matching)
# require unicode, and others (like write) require str.
#
# As befits the language, Python hides the distinction between
# unicode and str by converting between them silently, but
# *only* if all the bytes/code points involved are 7-bit ASCII.
# This means that if you're not careful, your program works
# fine on "hello, world" and fails on "hello, 世界". And of course,
# the obvious way to be careful - use static types - is unavailable.
# So the only way is trial and error to find where to put explicit
# conversions.
#
# Because more functions do implicit conversion to str (string of bytes)
# than do implicit conversion to unicode (string of code points),
# the convention in this module is to represent all text as str,
# converting to unicode only when calling a unicode-only function
# and then converting back to str as soon as possible.
def typecheck(s, t):
if type(s) != t:
raise hg_util.Abort("type check failed: %s has type %s != %s" % (repr(s), type(s), t))
# If we have to pass unicode instead of str, ustr does that conversion clearly.
def ustr(s):
typecheck(s, str)
return s.decode("utf-8")
# Even with those, Mercurial still sometimes turns unicode into str
# and then tries to use it as ascii. Change Mercurial's default.
def set_mercurial_encoding_to_utf8():
from mercurial import encoding
encoding.encoding = 'utf-8'
set_mercurial_encoding_to_utf8()
# Even with those we still run into problems.
# I tried to do things by the book but could not convince
# Mercurial to let me check in a change with UTF-8 in the
# CL description or author field, no matter how many conversions
# between str and unicode I inserted and despite changing the
# default encoding. I'm tired of this game, so set the default
# encoding for all of Python to 'utf-8', not 'ascii'.
