## Initiate again

Rk: useful when timezone has changed or ghostty command has been installed afterwards
    may require SUDO privilege

`miaou-bash --self-upgrade`

## debug, use of MIAOU_DEBUG

```bash
MIAOU_DEBUG=true miaou-bash <<EOF
echo this is still fine
false
echo SHOULD NOT APPEAR
EOF
```

## hooks.d/after-upgrade

To launch optional scripts after 'upgrade', you can create any hook regarding:

1. script should be stored in "$MIAOU_BASH_DIR/hooks.d/
2. script should be named with prefix 'after-upgrade', example: `after-upgrade-1.bash`
3. script should be executable, ie: `chmod +x after-upgrade-1.bash`

Be aware: no matter a failure happens during processing a hook, it will get bypassed!
As so the whole process of upgrading keeps running on.

Rk: hooks.d/ respects natural order,
ie: `after-upgrade-0.bash` will perform before `after-upgrade-1.bash`

## IDEA

### distinguish heredoc over pipe

```bash
miaou-bash <<EOF
echo HEREDOC
EOF
```

```bash
miaou-bash < <(echo 'echo PIPE1')
```

```bash
echo 'echo PIPE2' | miaou-bash
```

## TODO

* [ ] prompt should show up version with `+` when there is more than one commit,
      not yet versioned. ie: v0.0.0 + 2 commits more should display v0.0.0+
* [ ] semver_git_tag should append `RELEASE_NOTES.md` from this TODO markdown file,
      providing that NEW NOTE section below contains appropriate items
      to fulfill the current release note
* [ ] git log <LATEST_TAG>..HEAD --oneline
