install: allow installation of local packages
It may not be desirable to host all plugins on npm, allow for local packages to be installed given a package name with a `file:` prefix. This is still more restrictive than what yarn would support but allows us to still verify the thelounge compatibility by reading the package.json file. `yarn add` messes up with local filepaths and generates a lockfile that is "outdated" as far as any other yarn commands go, which makes them error out. For some reason `yarn install` fixes that and hence we run that after an install. Here's the diff of yarn.lock between the broken state after `yarn add file:$path` and `yarn install` --- yarn.lock.2.afterAdd 2021-06-02 00:10:52.365134018 +0200 +++ yarn.lock.3.afterinstall 2021-06-02 00:13:27.122760442 +0200 @@ -2194,7 +2194,7 @@ safe-buffer "^5.1.2" yallist "^3.0.3" -thelounge-plugin-shortcuts@/home/reto/sourcecode/thelounge-plugin-shortcuts: +"thelounge-plugin-shortcuts@file:../../sourcecode/thelounge-plugin-shortcuts": version "1.0.12" dependencies: thelounge "4.2.0" The only thing it does is switch an absolute path to a relative one for whatever reason.
