+# Terragrunt plugin

+## Prompt functions
+
+- `terragrunt_prompt_info`: shows the current workspace when in a Terragrunt project directory.
+
+- `terragrunt_version_prompt_info`: shows the current version of the `terragrunt` command.
+
+To use them, add them to a `PROMPT` variable in your theme or `.zshrc` file:
+
+```sh
+PROMPT='$(terragrunt_prompt_info)'
+RPROMPT='$(terragrunt_version_prompt_info)'
+```
+
+You can also specify the PREFIX and SUFFIX strings for both functions, with the following variables:
+
+```sh
+# for terragrunt_prompt_info
+ZSH_THEME_TERRAGRUNT_PROMPT_PREFIX="%{$fg[white]%}"
+ZSH_THEME_TERRAGRUNT_PROMPT_SUFFIX="%{$reset_color%}"
+# for terragrunt_version_prompt_info
+ZSH_THEME_TERRAGRUNT_VERSION_PROMPT_PREFIX="%{$fg[white]%}"
+ZSH_THEME_TERRAGRUNT_VERSION_PROMPT_SUFFIX="%{$reset_color%}"
+```
