# Changelog

## 0.6.4-dev

Features

* Configurable command hooks from `.asdfrc`
  Suppose a `foo` plugin is installed and provides a `bar` executable,
  The following hooks will be executed when set:

    ```shell
    pre_asdf_install_foo = echo will install foo version ${1}
    post_asdf_install_foo = echo installed foo version ${1}

    pre_asdf_reshim_foo = echo will reshim foo version ${1}
    post_asdf_reshim_foo = echo reshimmed foo version ${1}
    
    pre_foo_bar = echo about to execute command bar from foo with args: ${@}
    post_foo_bar = echo just executed command bar from foo with args: ${@}
    ```
* New shim version meta-data allows shims to not depend on a particular plugin
  nor on its relative executable path (#431)
  Upgrading requires shim re-generation and should happen automatically by `asdf-exec`:
  `rm -rf ~/.asdf/shims/` followed by `asdf reshim`
* Added lots of tests for shim execution.
  We now make sure that shim execution obeys plugins hooks like `list-bin-paths` and
  `exec-path`. 
* Shim exec is now performed by a new `bin/private/asdf-tool-exec` that might be faster
  for most common use case: (versions on local .tool-versions file) but fallbacks to
  slower `get_preset_version_for` which takes legacy formats into account.
* Shim exec recommends which plugins or versions to set when command is not found.
* `asdf reshim` without arguments now reshims all installed plugins (#407)

Fixed Bugs

* Allow many plugins to provide shims with same executable name (#431)
