an order of insects that comprises the butterflies and moths. They have four large scale-covered wings that bear distinctive markings, and larvae that are caterpillars. ORIGIN modern Latin (plural), from Greek lepis, lepid- ‘scale’ + pteron ‘wing.’
A life-enhancing code generator for everyday use.
What is lepidoptera?
Lepidoptera is a simple and easy to extend code generator for common every day projects.
Technically, Lepidoptera is a wrapper for rubigen which allows setting up code templates for arbitrary projects.
Lepidopteras code generators are structured in generator groups. A generators group is just a container for multiple generators, where as a generator is also called a generator type.
For the time being, Lepidoptera has code generators for the following project types (more to come):
$ sudo gem install lepidoptera
For aesthetic reason, you may also set a synonym alias
butterfly in your
alias butterfly='lep $1'
$ lep [options] <generator-group> <generator-type> <project-name>
with the following options:
-q, --quiet Suppress status output. -n, --new Create a new code generator stub in ~/.lepidoptera. -g, --git Create a git repository after code generation. -h, --help Print generator's options and usage.
Get a list of all local code generator groups:
Get a list of all code generators for a given generator group:
$ lep <generator-group>
Extending with own Code Generators
Since lepidoptera is based on Nic Williams Ruby generator framework rubigen, it is very simple to add new own private code generators.
1. Manual creation of new a code generator
Your own private code generators must reside in a folder
A new generator must satisfy the following code structure:
.lepidoptera └─ <generator-group>_generators └─ <generator-type> ├─ INFO ├─ <generator-type>_generator.rb └─ templates ├─ ... └─ ...
whereas every code generator type must contain the following files:
- an optional
INFOfile containing some additional project info to be displayed after the generation.
- a required generator file
<generator-type>_generator.rbwhich contains the generation rules.
- a required templates folder
templateswhich may contain multiple ERB templates for the code to be generated.
These ERB templates may contain variables as placeholders for the following information:
<%= name %>: Name of the project.
<%= author %>: Author of the project (OS Username).
2. Automatic creation of new a code generator
An easier way to create a new code generator is to automatically generate the above code generator stub into
To create a new code generator stub, use the
--new option and provide a generator group and a generator type:
$ lep -n <generator-group> <generator-type>
If the generator group does not exist already, a group folder
<generator-group>_generators will be created.
Embedded Code Generators
The following code generators are currently embedded within this project:
get List of all jquery generators:
$ lep jquery
generate code for a jquery plugin:
$ lep jquery plugin <plugin-name>
get List of all heroku generators:
$ lep heroku
generate code for a static page on heroku:
$ lep heroku static <page-name>
generate code for a sinatra application on heroku:
$ lep heroku sinatra <app-name>
