# Planter [![Gem](https://img.shields.io/gem/v/planter-cli.svg)](https://rubygems.org/gems/planter-cli) [![GitHub license](https://img.shields.io/github/license/ttscoff/planter-cli.svg)](./LICENSE.txt) Plant a directory structure and files using templates. ## Installation gem install planter-cli If you run into errors, try `gem install --user-install planter-cli`, or as a last ditch effort, `sudo gem install planter-cli`. ### Optional If [Gum](https://github.com/charmbracelet/gum) is available it will be used for command line input. ## Configuration Planter's base configuration is in `~/.config/planter/planter.yml`. This file can contain any of the keys used in templates (see below) and will serve as a base configuration for all templates. Any key defined in this file will be overridden if it exists in a template. ### Scripts. Scripts for execution after planting can be stored in `~/.config/planter/scripts` and referenced by filename only. Alternatively, scripts may be stored within a template in a `_scritps` subfolder. Scripts can be executable files in any language, and receive the template directory and the planted directory as arguments $1 and $2. ### Templates Templates are directories found in `~/.config/planter/templates/[TEMPLATE_NAME]`. All files and directories inside of these template directories are copied when that template is called. Filenames, directory names, and file contents can all use template placeholders. Template placeholders are defined with `%%KEY%%`, where key is the key defined in the `variables` section of the configuration. %%KEY%% placeholders can be used in directory/file names, and in the file contents. These work in any plain text or RTF format document, including XML, so they can be used in things like Scrivener templates and MindNode files as well. Each template contains a `_planter.yml` file that defines variables and other configuration options. The file format for all configuration files is [YAML](https://yaml.org/spec/1.2.2/). First, there's a `variables` section that defines variables used in the template. It's an array of dictionaries, each dictionary defining one variable. The required fields are `key` (the key used to insert the variable) and `prompt` (the text provided on the command line when asking for the variable). The rest are optional: ```yaml variables: - key: var_key prompt: Prompt text type: string # [string,multiline,float,integer,number,date] defaults to string # value: (force value, string can include %%variables%% and regexes will be replaced. For date type can be today, time, now, etc.) default: Untitled min: 1 max: 5 script: # array of scripts, args passed as [script and args] TEMPLATE_DIR PWD - process.py git_init: false # if true, initialize a git repository in the newly-planted directory files: # Dictionary for file handling (see [File-specific handling](#file-specific-handling)) replacements: # Dictionary of pattern/replacments for regex substitution, see [Regex replacements](#regex-replacements) repo: # If a repository URL is provided, it will be pulled and duplicated instead of copying a file structure ``` #### Default values in template strings In a template you can add a default value for a placholder by adding `%default value` to it. For example, `%%project%Default Project%%` will set the placeholder to `Default Project` if the variable value matches the default value in the configuration. This allows you to accept the default on the command line but have a different value inserted in the template. To use another variable in its place, use `$KEY` in the placeholder, e.g. `%%project%$title%%` will replace the `project` key with the value of `title` if the default is selected. Modifiers can be used on either side of the `%`, e.g. `%%project%$title:snake%%`. ### File-specific handling A `files` dictionary can specify how to handle specific files. Options are `copy`, `overwrite`, `merge`, or `ask`. The key for each entry is a filename or glob that matches the source filename (accounting for template variables if applicable): ```yaml files: "*.py": merge "%%title%%.md": overwrite ``` If `merge` is specified, then the source file is scanned for merge comments and those are merged if they don't exist in the copied/existing file. If no merge comments are defined, then the entire contents of the source file are appended to the destination file (unless the file already matches the source). Merge comments start with `merge` and end with `/merge` and can have any comment syntax preceding them, for example: ``` // merge Merged content // /merge ``` Or ``` # merge Merged content # /merge ``` By default files that already exist in the destination directory are not overwritten, and merging allows you to add missing parts to a Rakefile or Makefile, for example. If `ask` is specified, a memu will be provided on the command line asking how to handle a file. If the file doesn't already exist, you will be asked only whether to copy the file or not. If it does exist, `overwrite` and `merge` options will be added. ### Regex replacements In addition to manually-placed template variables, you can also specify regular expressions for replacement. The `replacements` dictionary is a set of key/value pairs with the regex pattern as the key, and the replacement as the value. Both should be quoted in almost all circumstances. ```yaml replacements: "Planter": "%%title:cap%%" "(main|app)\.js": "%%script:lower%%.js" ``` Replacements are performed on both file/directory names and file contents. ## Usage The executable for Planter is `plant`. You can run `plant TEMPLATE` in any directory and TEMPLATE will be planted in the current directory. You can also use `--in PATH` to plant in another directory. ``` Usage: planter [options] TEMPLATE --defaults Accept default values for all variables -i, --in TARGET Plant in TARGET instead of current directory -o, --overwrite Overwrite existing files -k, --var=KEY:VALUE,KEY:VALUE... Pass a variable on the command line as KEY:VALUE pairs. Can be used multiple times. -d, --debug Display version number -h, --help Display this screen, or list variables for template argument -v, --version Display version number ``` Files will be copied, but existing files will not be overwritten unless otherwise noted in the `files` configuration for the template. Some directories like `.git` and files like `_planter.yml` are automatically ignored. If you want to create a git repository, include the `git_init: true` key in config. When `plant` is run, any defined variables will be requested on the command line using the defined prompt. If a `default` key is specified, hitting return at the prompt will accept the default value. Variables can be passed on the command line with `--var KEY:VALUE`. This flag can contain a comma-separated list, e.g. `--var KEY:VALUE,KEY:VALUE` or used multiple times in the same command. Variables passed on the command line will not be prompted for when processing variables. ## Documentation - [YARD documentation][RubyDoc] is hosted by RubyDoc.info. - [Interactive documentation][Omniref] is hosted by Omniref.
