Hi pacman devs! Allan pointed me to https://wiki.archlinux.org/index.php/User:Allan/Pacman_Hooks in his blog comments, and I think it's great that such hooks will be added to pacman (hopefully for the next release)! I've got a small suggestion for the file format for specifying the hooks. If it is already set in stone please disregard this email; This is just in case it's still open to brainstorming: Did you consider separating the options by whether they define the trigger, or specify the action to be run for each instance where the hook was triggered? This might make the format more self-explanatory, and more extensible in case support for more complicated triggers/actions is added in the future. So instead of: [Hook] Description = Add info files to the info directory Type = PostTransaction [Target] File = /usr/share/info/* Exec = install-info %f /usr/share/info/dir &>/dev/null It might read: [Hook] Description = Add info files to the info directory [Trigger] FileInstalled = /usr/share/info/* [Action] Stage = PostTransaction Exec = install-info %f /usr/share/info/dir &>/dev/null
