You can limit the branch name to a certain length by truncating long names.
Customizations available are:
| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_VCS_SHORTEN_LENGTH`|None|This field determines how many characters to show.|
|`POWERLEVEL9K_VCS_SHORTEN_MIN_LENGTH`|None|This field determines minimum branch length. Branch name will be truncated if its length greater than this field.|
|`POWERLEVEL9K_VCS_SHORTEN_STRATEGY`|None|This field determines how branch name should be truncated. See the table below for more information.|
|`POWERLEVEL9K_SHORTEN_DELIMITER`|`...`|Delimiter to use in truncated strings. This can be any string you choose, including an empty string if you wish to have no delimiter.|
| Strategy Name | Description |
|---------------|-------------|
|`truncate_middle`|Truncates the middle part of a branch. E.g. branch name is `1234-super_super_long_branch_name`, then it will truncated to `1234-..._name`, if `POWERLEVEL9K_VCS_SHORTEN_LENGTH=5` is also set (controls the amount of characters to be left).|
|`truncate_from_right`|Just leaves the beginning of a branch name untouched. E.g. branch name will be truncated like so: `1234-...`. How many characters will be untouched is controlled by `POWERLEVEL9K_VCS_SHORTEN_LENGTH`.|
For example, if you want to truncate `1234-super_super_long_branch_name` to `1234-..` and don't do it with `development`:
```zsh
POWERLEVEL9K_VCS_SHORTEN_LENGTH=4
POWERLEVEL9K_VCS_SHORTEN_MIN_LENGTH=11
POWERLEVEL9K_SHORTEN_STRATEGY="truncate_from_right"
POWERLEVEL9K_VCS_SHORTEN_DELIMITER=".."
```
