The install.sh does everything for you. Here's how it works:
The script will create symlinks to all of the dotfiles located in the files directory of this repo. You must not move or delete this repo after installing, or the symlinks will be broken and you will have to call install.sh again.
Sometimes you want exactly the same dotfile across all your machines except for a small change, for example, a different dpi. This is often possible if the config for a program allows you to include another local config file or reference environment variables, but this is not a universal solution. To cover every case, you can use this template system. Inside the templates directory there is a config directory which consists of YAML files defining local configuration such as dpi, and a files directory consisting of templated dotfiles. A templated dotfile is a regular dotfile containing placeholders. A placeholder is anything in curly braces and @ signs, e.g. {@ dpi @}. When the real dotfiles are generated from the templates, these placeholders will get replaced from the relevant config file. For example, if you need to generate dotfiles for a high dpi setup, you would run ./generate-from-templates.py -c high-dpi, referring to the high-dpi.yml config file. If a particular placeholder doesn't exist in the specified config file, it will use the default.yml config as a fallback.
The install.sh script will install vim-plug and run PlugInstall in neovim automatically. You shouldn't need to do anything.
When an edit to a dotfile is pushed, you don't need to run install.sh. Simply pull the repo. This is because the dotfile in your home directory is symlinked. For newly added files or neovim plugins, run install.sh. If a templated dotfile is changed, run generate-from-templates.py.
