This is g-sorcery backend for Python PyPI packages.
emerge -va gs-pypi
This will install all the necessary dependencies, including g-sorcery with BSON support, layman with g-sorcery support and pymongo (used for BSON manipulation).
There are two ways of using gs-pypi
Using gs-pypi with layman
It the the recommend way and I strongly suggest it.
Then you should just run layman -L as
root and find an overlay you want. Type of overlay will be
displayed as g-sorcery. Then you add this overlay as
usually and emerge packages you want. It's all you need to do. Example:
layman -L
layman -a pypi
emerge -va pycallgraph
There is 1 gs-pypi overlay currently: pypi.
When using gs-pypi with layman you can populate overlay only with packages you want. To do so you should add a section named gs-pypi to /etc/g-sorcery/g-sorcery.cfg. In this section you can add entries named REPO_packages (REPO here is the name of repository you want to add -- pypi) which are space separated lists of packages you need. Note, that at the moment gs-pypi doesn't support dependencies for pypi packages, so you need to add to this list package itself and all its dependencies.
[main]
package_manager=portage
[gs-pypi]
pypi_packages=pycallgraph
I strongly recommend to do so, as pypi overlay is quite big and you may be do not want generate all the ebuilds from it. To list available packages use the list command from the next section giving it appropriate layman overlay directory as argument.
In this case you should create an overlay (see portage documentation), sync it and populate it with one or more ebuilds. Then ebuilds could be installed by emerge or by gs-pypi tool. This is not the recommended way and may be removed in the future.
Create new user overlay:
gs-pypi -o $OVERLAY_DIRECTORY -r pypi sync
gs-pypi -o $OVERLAY_DIRECTORY -r pypi generate-tree --digest
List packages:
gs-pypi -o $OVERLAY_DIRECTORY -r pypi list
Install any package you want:
gs-pypi -o $OVERLAY_DIRECTORY -r pypi install $PACKAGE
Note, that if you call generate-tree command your overlay will be wiped and overlay tree for a given repository will be generated. Be careful!
See man page of gs-pypi for further information.
