petridish

If you have heard of the cookiecutter project, petridish is a rust implementation of it.

Features

Feature	Description
Cross platform	Windows, Linux, MacOS
More flexible configuration	`petridish` use toml file to define the template variables
More humanized prompt	support different kinds of prompt (`input`, `select`, `multi select`, `confirm`)
Powerful template engine	we use `tera` as our template engine, which is based on Jinja2/Django
One binary	one binary run everywhere
Manage cached templates	If you download a remote template, it will be cached, so later you can just use its name without download it again. You can also `list` or `remove` these cached templates

Usage

Like cookiecutter, you should provide directory structure like this:

Let's have a look at the petridish.toml file:

[petridish]
project_prompt = "project name?"
project_var_name = "project_name"
short_description = "This is an awesome template"

[[prompts]]
name = "name"
prompt = "what's your name"
type = "string"

[[prompts]]
name = "age"
choices = [10, 20, 30]
default = 20
type = "number"

[[prompts]]
name = "hobby"
choices = ["running", "swimming"]
multi = true
type = "string"

[[prompts]]
name = "is_geek"
type = "bool"
default = true

Remote git abbreviations

petridish knows abbreviations for Github(gh) and GitLab(gl) projects

The format should be like <abbreviation>[+<protocol>]:<namespace>/<project>

protocol can be: https, http, ssh, (default is https)

$ petridish new gh+https:petridish-dev/example
$ petridish new example # later you can just use its name

If the remote http(s) project is private, petridish will prompt to ask username and password for authorization.

Demo

Template

A Tera template is just a text file where variables and expressions get replaced with values when it is rendered. The syntax is based on Jinja2 and Django templates.

There are 3 kinds of delimiters and those cannot be changed:

{{ and }} for expressions
{% and %} for statements
{# and #} for comments

More syntax details can be found in tera.
