This script supports publishing Pystache to PyPI.
|
|
|
|
This docstring contains instructions to Pystache maintainers on how
|
|
to release a new version of Pystache.
|
|
|
|
(1) Prepare the release.
|
|
|
|
Make sure the code is finalized and merged to master. Bump the version
|
|
number in setup.py, update the release date in the HISTORY file, etc.
|
|
|
|
Generate the reStructuredText long_description using--
|
|
|
|
$ python setup.py prep
|
|
|
|
and be sure this new version is checked in. You must have pandoc installed
|
|
to do this step:
|
|
|
|
http://johnmacfarlane.net/pandoc/
|
|
|
|
It helps to review this auto-generated file on GitHub prior to uploading
|
|
because the long description will be sent to PyPI and appear there after
|
|
publishing. PyPI attempts to convert this string to HTML before displaying
|
|
it on the PyPI project page. If PyPI finds any issues, it will render it
|
|
instead as plain-text, which we do not want.
|
|
|
|
To check in advance that PyPI will accept and parse the reST file as HTML,
|
|
you can use the rst2html program installed by the docutils package
|
|
(http://docutils.sourceforge.net/). To install docutils:
|
|
|
|
$ pip install docutils
|
|
|
|
To check the file, run the following command and confirm that it reports
|
|
no warnings:
|
|
|
|
$ python setup.py --long-description | rst2html.py -v --no-raw > out.html
|
|
|
|
See here for more information:
|
|
|
|
http://docs.python.org/distutils/uploading.html#pypi-package-display
|
|
|
|
(2) Push to PyPI. To release a new version of Pystache to PyPI--
|
|
|
|
http://pypi.python.org/pypi/pystache
|
|
|
|
create a PyPI user account if you do not already have one. The user account
|
|
will need permissions to push to PyPI. A current "Package Index Owner" of
|
|
Pystache can grant you those permissions.
|
|
|
|
When you have permissions, run the following:
|
|
|
|
python setup.py publish
|
|
|
|
If you get an error like the following--
|
|
|
|
Upload failed (401): You must be identified to edit package information
|
|
|
|
then add a file called .pyirc to your home directory with the following
|
|
contents:
|
|
|
|
[server-login]
|
|
username: <PyPI username>
|
|
password: <PyPI password>
|
|
|
|
as described here, for example:
|
|
|
|
http://docs.python.org/release/2.5.2/dist/pypirc.html
|
|
|
|
(3) Tag the release on GitHub. Here are some commands for tagging.
|
|
|
|
List current tags:
|
|
|
|
git tag -l -n3
|
|
|
|
Create an annotated tag:
|
|
|
|
git tag -a -m "Version 0.5.1" "v0.5.1"
|
|
|
|
Push a tag to GitHub:
|
|
|
|
git push --tags defunkt v0.5.1
