For every command yadm supports, a program can be provided to run before or
|
||
|
|
after that command. These are referred to as "hooks". yadm looks for hooks in
|
||
|
|
the directory
|
||
|
|
`$HOME/.config/yadm/hooks`.
|
||
|
|
Each hook is named using a prefix of `pre_` or `post_`, followed by the command
|
||
|
|
which should trigger the hook. For example, to create a hook which is run after
|
||
|
|
every `yadm pull` command, create a hook named `post_pull`.
|
||
|
|
Hooks must have the executable file permission set.
|
||
|
|
|
||
|
|
If a `pre_` hook is defined, and the hook terminates with a non-zero exit
|
||
|
|
status, yadm will refuse to run the yadm command. For example, if a
|
||
|
|
`pre_commit` hook is defined, but that command ends with a non-zero exit status,
|
||
|
|
the `yadm commit` will never be run. This allows one to "short-circuit" any
|
||
|
|
operation using a `pre_` hook.
|
||
|
|
|
||
|
|
Hooks have the following environment variables available to them at runtime:
|
||
|
|
|
||
|
|
