The current behavior in shims is to check if there's an existing shim for
which the shim we're currently checking is a prefix. For example, if the shim
has
# asdf-plugin: erlang 21.2.6
Then adding a shim for `erlang 21.2` will fail.
This updates the `grep` check to match the end of the line as well so we
always get a full version check.
Fixes#517
Suppose a `foo` plugin is installed and provides a `bar` executable.
The following hooks will be executed when set in `.asdfrc`:
```shell
post_asdf_install_foo = echo installed 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: ${@}
```
Features
* 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.
Fixed Bugs
* Allow many plugins to provide shims with same executable name (#431)
