dot-home: Version-controlled Construction of Unix User Configuration

Current State

This is still in the early design stages; both documentation and code are woefully incomplete.

Introduction

dot-home is a framework for version control, synchronization and building of configuration and other files typically found in a $HOME (often written ~) directory.

Configuration and other information is stored in subdirectories under ~/.home; these subdirectories (which are usually working copies of git repos) are called "modules." The dot-home system itself is placed in ~/.home/_dot-home; it's the "master" module that handles dealing with the building, installation and management of material found in all the modules, including itself.

The setup script, _dot-home/bin/dot-home-setup, runs the symlinker which goes through all the files in ~/.home/*/{bin,dot} and does the following.

For directories under ~/.home/*/bin/ and ~/.home/*/share it creates a directory at the same path under ~/.local/bin/ or ~/.local/share. For files it creates a symlink at the same path under the same directory whose target is a relative path back to the file under ~/.home. However, files ending in .inb[0-9] are not linked. (These are template files used to build new files.)

For directories and files under ~/.home/*/dot/ the actions are the same except that the path above is translated to ~/.; i.e., the file ~/.home/module/dot/foo/bar will generate a symlink ~/.foo/bar pointing to it.

The modules and files within them are processed in lexical order with the first directory or file encountered taking priority. Dangling links created by the dot-home system will be removed before the new link is created, but any other links, whether previously created by this dot-home run or created from outside the dot-home system, will generate a conflict warning and will be left untouched.

Usage of ~/.local/

The idea of a ~/.local directory with a structure parallel to /usr/local (and by implication, /usr) may have originated with the XDG Base Directory Specification, which specifies that $XDG_DATA_HOME defaults to $HOME/.local/share. The general idea has since been adopted by other systems, including:

  • Python: the per-user site packages directory is ~/.local. (2008-01; v2.6+, v3.0+)
  • Ubuntu 16.04: the default profile given to new users, /etc/skel/.profile, adds $HOME/.local/bin to the path. (2016-04)
You can’t perform that action at this time.
