 |`truncate_from_right`|Just leaves the beginning of a folder name untouched. E.g. your folders will be truncated like so: "/ro../Pr../office". How many characters will be untouched is controlled by `POWERLEVEL9K_SHORTEN_DIR_LENGTH`.|
 |`truncate_with_package_name`|Search for a `package.json` or `composer.json` and prints the `name` field to abbreviate the directory path. The precedence and/or files could be set by `POWERLEVEL9K_DIR_PACKAGE_FILES=(package.json composer.json)`. If you have [jq](https://stedolan.github.io/jq/) installed, it will dramatically improve the speed of this strategy.|
 |`truncate_with_folder_marker`|Search for a file that is specified by `POWERLEVEL9K_SHORTEN_FOLDER_MARKER` and truncate everything before that (if found, otherwise stop on $HOME and ROOT).|
