ZC Buildout recipe to execute a commande line in it's own shell
Project description
SORRY about the 0.5 release being buggy. uploaded a new 0.5. life should work again for everyone.
FYI, I no longer use buildout, and am not actively maintaining this project. If you love it or use it, and want it upgraded to python3/etc. please send a patch, or just offer to take the project over.
=====================
cp.recipe.cmd package

.. contents::
What is cp.recipe.cmd ?
=======================
This recipe is used to run one or more command lines.
I stole this from iw.recipe.cmd (http://pypi.python.org/pypi/iw.recipe.cmd/0.1)
It works differently tho, when it comes to executing shell commands. iw.recipe.cmd would push each command out separately in it's own shell. Here I push them out to a shell script, and then run the shell script. This way things like CD and other things that require state within the shell work great.
Also, I changed the way it works in the config file.
we have 2 options in the command.
[commandexample]
recipe = cp.recipe.cmd
install_cmds =
echo "install commands go here"
cd /tmp
echo `pwd`
echo 'see, I exist in one shell instance.'
update_cmds =
echo "update commands go here"
On install, install_cmds will be turned into a shell script, and then ran.
on update, update_cmds will be turned into a shell script and then ran. If you want update_cmds to be the same you can do something like this:
update_cmds = ${commandexample:install_cmd}
(where commandexample is the name of your part)
python code execution is unchanged in this version, and below are the original docs.
We need a config file::
>>> cfg = """
... [buildout]
... parts = cmds
...
... [cmds]
... recipe = iw.recipe.cmd
... on_install=true
... cmds= %s
... """
>>> test_file = join(sample_buildout, 'test.txt')
>>> cmds = 'touch %s' % test_file
>>> write(sample_buildout, 'buildout.cfg', cfg % cmds)
Ok, so now we can touch a file for testing::
>>> print system(buildout)
Installing cmds.
>>> 'test.txt' in os.listdir(sample_buildout)
True
And remove it::
>>> test_file = join(sample_buildout, 'test.txt')
>>> cmds = 'rm -f %s' % test_file
>>> write(sample_buildout, 'buildout.cfg', cfg % cmds)
>>> print system(buildout)
Uninstalling cmds.
Installing cmds.
>>> 'test.txt' in os.listdir(sample_buildout)
False
We can run more than one commands::
>>> cmds = '''
... touch %s
... rm -f %s
... ''' % (test_file, test_file)
>>> test_file = join(sample_buildout, 'test.txt')
>>> cmds = 'rm -f %s' % test_file
>>> write(sample_buildout, 'buildout.cfg', cfg % cmds)
>>> print system(buildout)
Updating cmds.
>>> 'test.txt' in os.listdir(sample_buildout)
False
We can also run some python code::
>>> cfg = """
... [buildout]
... parts = py py2
...
... [py]
... recipe = iw.recipe.cmd:py
... on_install=true
... cmds=
... >>> sample_buildout = buildout.get('directory', '.')
... >>> print os.listdir(sample_buildout)
... >>> shutil.rmtree(os.path.join(sample_buildout, "bin"))
... >>> print os.listdir(sample_buildout)
... [py2]
... recipe = iw.recipe.cmd:py
... on_install=true
... cmds=
... >>> def myfunc(value):
... ... return value and True or False
... >>> v = 20
... >>> print myfunc(v)
... """
>>> write(sample_buildout, 'buildout.cfg', cfg)
Ok, so now we run it::
>>> print system(buildout)
