I recently released Emacsagist, an Emacs front-end for searching Packagist.
You can download Emacsagist via the MELPA repository with
M-x list-packages or Cask. From there, you can run
M-x emacsagist-search, type in a search term, and Emacsagist will give you search results. You can press return on any package name to get full details.
Now there’s one less reason to leave Emacs for PHP developers.
