From: Brian Warner Date: Mon, 5 Dec 2011 04:40:01 +0000 (-0800) Subject: setup.py: get version from git or darcs X-Git-Tag: allmydata-tahoe-1.9.1~12 X-Git-Url: https://git.rkrishnan.org/%5B/frontends/%22file:/flags/?a=commitdiff_plain;h=c2ad73a65049989098c3355a04c038832d64ddf0;p=tahoe-lafs%2Ftahoe-lafs.git setup.py: get version from git or darcs This replaces the setup.cfg aliases that run "darcsver" before each major command with the new "update_version". update_version is defined in setup.py, and tries to get a version string from either darcs or git (or leaves the existing _version.py alone if neither VC metadata is available). Also clean up a tiny typo in verlib.py that messed up syntax hilighting. --- diff --git a/setup.cfg b/setup.cfg index 64210af2..7232eb9a 100644 --- a/setup.cfg +++ b/setup.cfg @@ -37,10 +37,10 @@ find_links=misc/dependencies tahoe-deps ../tahoe-deps # (See http://tahoe-lafs.org/trac/tahoe-lafs/ticket/142 .)
