homesick help
## .homesick_subdir
`homesick symlink` basically makes symlink to only first depth in `castle/home`. If you want to link nested files/directories, please use .homesick_subdir.
For example, when you have castle like this:
castle/home
`-- .config
`-- fooapp
|-- config1
|-- config2
`-- config3
and have home like this:
$ tree -a
~
|-- .config
| `-- barapp
| |-- config1
| |-- config2
| `-- config3
`-- .emacs.d
|-- elisp
`-- inits
You may want to symlink only to `castle/home/.config/fooapp` instead of `castle/home/.config` because you already have `~/.config/barapp`. In this case, you can use .homesick_subdir. Please write "directories you want to look up sub direcoties (instead of just first depth)" in this file.
castle/home/.homesick_subdir
.config
and run `homesick symlink CASTLE`. The result is:
~
|-- .config
| |-- barapp
| | |-- config1
| | |-- config2
| | `-- config3
| `-- fooapp -> castle/home/.config/fooapp
`-- .emacs.d
|-- elisp
`-- inits
Or `homesick track NESTED_FILE CASTLE` adds a line automatically. For example:
homesick track .emacs.d/elisp castle
castle/home/.homesick_subdir
.config
.emacs.d
home directory
~
|-- .config
| |-- barapp
| | |-- config1
| | |-- config2
| | `-- config3
| `-- fooapp -> castle/home/.config/fooapp
`-- .emacs.d
|-- elisp -> castle/home/.emacs.d/elisp
`-- inits
and castle
castle/home
|-- .config
| `-- fooapp
| |-- config1
| |-- config2
| `-- config3
`-- .emacs.d
`-- elisp
