开源软件名称:haml/haml开源软件地址:https://github.com/haml/haml开源编程语言:Ruby 81.2%开源软件介绍:HamlHaml is a templating engine for HTML. It's designed to make it both easier and more pleasant to write HTML documents, by eliminating redundancy, reflecting the underlying structure that the document represents, and providing an elegant syntax that's both powerful and easy to understand. Basic UsageHaml can be used from the command line or as part of a Ruby web framework. The first step is to install the gem: gem install haml After you write some Haml, you can run haml document.haml to compile it to HTML. For more information on these commands, check out haml --help To use Haml programmatically, check out the YARD documentation. Using Haml with RailsTo use Haml with Rails, simply add Haml to your Gemfile and run gem 'haml' If you'd like to replace Rails's Erb-based generators with Haml, add haml-rails to your Gemfile as well. FormattingThe most basic element of Haml is a shorthand for creating HTML: %tagname{:attr1 => 'value1', :attr2 => 'value2'} Contents No end-tag is needed; Haml handles that automatically. If you prefer HTML-style attributes, you can also use: %tagname(attr1='value1' attr2='value2') Contents Adding %tagname#id.class In fact, when you're using the #foo Hello! becomes <div id='foo'>Hello!</div> Haml uses indentation to bring the individual elements to represent the HTML structure. A tag's children are indented beneath than the parent tag. Again, a closing tag is automatically added. For example: %ul
%li Salt
%li Pepper becomes: <ul>
<li>Salt</li>
<li>Pepper</li>
</ul> You can also put plain text as a child of an element: %p
Hello,
World! It's also possible to embed Ruby code into Haml documents. An equals sign, %p
Date/Time:
- now = DateTime.now
%strong= now
- if now > DateTime.parse("December 31, 2006")
= "Happy new " + "year!" Haml provides far more tools than those presented here. Check out the reference documentation for full details. IndentationHaml's indentation can be made up of one or more tabs or spaces. However, indentation must be consistent within a given document. Hard tabs and spaces can't be mixed, and the same number of tabs or spaces must be used throughout. ContributingContributions are welcomed, but before you get started please read the guidelines. After forking and then cloning the repo locally, install Bundler and then use it to install the development gem dependencies: gem install bundler
bundle install Once this is complete, you should be able to run the test suite: rake You'll get a warning that you need to install haml-spec, so run this: git submodule update --init At this point Note that you can also run just one test out of the test suite if you're working on a specific area: ruby -Itest test/helper_test.rb -n test_buffer_access Haml currently supports Ruby 2.0.0 and higher, so please make sure your changes run on 2.0+. TeamCurrent MaintainersAlumniHaml was created by Hampton Catlin, the author of the original implementation. Hampton is no longer involved in day-to-day coding, but still consults on language issues. Natalie Weizenbaum was for many years the primary developer and architect of the "modern" Ruby implementation of Haml. Norman Clarke was the primary maintainer of Haml from 2012 to 2016. LicenseSome of Natalie's work on Haml was supported by Unspace Interactive. Beyond that, the implementation is licensed under the MIT License.
