I need to find all packages on
pip search django-
pip search django-
pip search admin
aleckxe, I believe this is the one-liner you are looking for.
pip search django | grep -P "^django-(?=[-\w]*?admin)[-\w]+"
As suggested by chromate in the comment below, you could easily pipe to sort for a sorted list if you wished.
pip search django | grep -P "^django-(?=[-\w]*?admin)[-\w]+" | sort
Let me know if you'd like any tweaks.
After the pipe
| which redirects the output of the
pip command to
<stdin> for the grep command, we enter grep in Perl mode
-P. This is necessary, otherwise we would not be allowed to use a lookahead.
We anchor the pattern at the beginning of the string with
^ and immediately match
django- as a literal. We then assert (lookahead) that at this position we would be able to match any number of dashes or word characters (which include digits and underscores), followed by the literal string
Having made this assertion (which is a form of validation), we now match as many dashes and word characters as we can, which should take us to the end of the module name.
There are several ways of expressing this and for this simple pattern the variations are largely a matter of preference or mood.
If you ever wanted to change this to match
django- patterns that contain
someword, just replace
django-smoke-admin - django-smoke-admin tests that all admin pages for all registered models responds correctly (HTTP 200). django-adminskin - UNKNOWN django-admin-exporter - Simple admin actions to download/export selected items in CSV, JSON, XML, etc. django-treeadmin-fork-alt-storage - Tree UI for mptt-managed models, extracted from FeinCMS. This is a fork with support for alternative storage engines django-relatedadminwidget - Get edit and delete links in your django admin. A utility class to let your model admins inherit from. django-admin-langswitch - Adds easy language switch in admin django-authy-admin - A drop in replacement for django's default admin site that provides two-factor authentication via authy's REST API. django-frontendadmin - A a set of templatetags to allow an easy and unobstrusive way to edit model-data in the frontend of your page. django-admin-app-names-singleton - Django admin enhancer django-mobileadmin - The Django admin interface for mobile devices.
(The list goes on.)
By the way, looking at the pip search documentation, I don't see a way of doing this without the pipe.
