##### Use range
Commands like `commit-log` and `commit-notes` has a range option. Supported range types are: `tag`, `date` and `hash`.
By default, it's used [--date=short](https://git-scm.com/docs/git-log#Documentation/git-log.txt---dateltformatgt) at `git log`, all dates returned from it will be in `YYYY-MM-DD` format.
Range `tag` will use `git describe` to get the last tag available if `start` is empty, the others types won't use the existing tags, it's recommended to always use a start limit in a old repository with a lot of commits. This behavior was maintained to not break the retrocompatibility.
Range `date` use git log `--since` and `--until`, it's possible to use all supported formats from [git log](https://git-scm.com/docs/git-log#Documentation/git-log.txt---sinceltdategt), if `end` is in `YYYY-MM-DD` format, `sv` will add a day on git log command to make the end date inclusive.
Range `tag` and `hash` are used on git log [revision range](https://git-scm.com/docs/git-log#Documentation/git-log.txt-ltrevisionrangegt). If `end` is empty, `HEAD` will be used instead.
```bash
# get commit log as json using a inclusive range
git-sv commit-log --range hash --start 7ea9306~1 --end c444318
# return all commits after last tag
git-sv commit-log --range tag
```
##### Use validate-commit-message as prepare-commit-msg hook
Configure your .git/hooks/prepare-commit-msg
