Config file sharing
===================
[](https://github.com/egor-tensin/config-links/actions/workflows/ci.yml)
[](https://github.com/egor-tensin/config-links/actions/workflows/debian.yml)
[](https://github.com/egor-tensin/config-links/actions/workflows/ppa.yml)
* Store your files in a repository.
* Checkout it on any machine.
* Create and maintain symlinks to these files easily.
How it works
------------
Actual files are stored in directories with names matching the `%VAR_NAME%`
pattern.
The part between the percent signs is the name of an environment variable.
Every file in such directory gets a symlink in the directory pointed to by the
environment variable.
Directory hierarchies are preserved.
A database of symlinks is maintained in case a shared file is deleted (the
corresponding symlink is then deleted too).
The default database file name is "links.bin", maintained in the top-level
directory with shared files.
For a complete usage example, see below.
Installation
------------
* For Arch Linux, use the [AUR package].
* For Ubuntu, use the [PPA].
* Alternatively, just checkout this repository.
* For macOS, see [this section].
[AUR package]: https://aur.archlinux.org/packages/config-links/
[PPA]: https://launchpad.net/~egor-tensin/+archive/ubuntu/config-links
[this section]: #macos
Usage
-----
Symlinks are created & maintained by `links-update`.
```
usage: links-update [-h|--help] [-d|--database PATH] [-s|--shared-dir DIR] [-m|--mode MODE] [-n|--dry-run]
```
To remove all symlinks, use `links-remove`.
```
usage: links-remove [-h|--help] [-d|--database PATH] [-s|--shared-dir DIR] [-n|--dry-run]
```
In this example, symlinks to files in "/test/src" must appear in "/test/dest".
```
$ tree /test/dest/
/test/dest/
0 directories, 0 files
$ tree /test/src/
/test/src/
└── %DEST%
├── a
│ └── b
│ └── c
│ └── test.txt
└── foo
└── bar
└── baz
6 directories, 2 files
$ echo "$DEST"
/test/dest
$ ./links-update --shared-dir /test/src/
...
$ tree /test/dest/
/test/dest/
├── a
│ └── b
│ └── c
│ └── test.txt -> /test/src/%DEST%/a/b/c/test.txt
└── foo
└── bar
└── baz -> /test/src/%DEST%/foo/bar/baz
5 directories, 2 files
```
For my personal real-life usage examples, see
* [my dotfiles],
* configuration files for various [Windows apps].

Development
-----------
Run local tests using
make test
Run Docker tests using
make test/docker
Run all tests using
make test/all
Limitations
-----------
Variable names must be alphanumeric.
More precisely, the corresponding directory names must match the
`^%[_[:alpha:]][_[:alnum:]]*%$` regular expression.
Consequently, `ProgramFiles(x86)` (and other weird variable names Windows
allows) are not supported.
A special variable name `CONFIG_LINKS_ROOT` is resolved to the root path, "/".
macOS
-----
macOS is supported on a basic level.
GNU coreutils and findutils are required, which you can install using Homebrew.
Don't forget to add them to PATH!
Cygwin
------
These scripts rely on the availability of native symlinks.
On Windows/NTFS, they require Administrator privileges.
Remember that in order to force `ln` to use native NTFS symlinks, your `CYGWIN`
environment variable **must** include either `winsymlinks:native` or
`winsymlinks:nativestrict`.
