开源软件名称：paolochiodi/htmlcompressor开源软件地址：https://github.com/paolochiodi/htmlcompressor开源编程语言：Ruby 82.3%开源软件介绍：HtmlcompressorPut your html on a dietHtmlcompressor provides tools to minify html code. It includes
Please note that Htmlcompressor is still in alpha version and need some additional love. UsageUsing the compressor class is straightforward: compressor = HtmlCompressor::Compressor.new
compressor.compress('<html><body><div id="compress_me"></div></body></html>')The compressor ships with basic and safe default options that may be overwritten passing the options hash to the constructor: options = {
:enabled => true,
:remove_spaces_inside_tags => true,
:remove_multi_spaces => true,
:remove_comments => true,
:remove_intertag_spaces => false,
:remove_quotes => false,
:compress_css => false,
:compress_javascript => false,
:simple_doctype => false,
:remove_script_attributes => false,
:remove_style_attributes => false,
:remove_link_attributes => false,
:remove_form_attributes => false,
:remove_input_attributes => false,
:remove_javascript_protocol => false,
:remove_http_protocol => false,
:remove_https_protocol => false,
:preserve_line_breaks => false,
:simple_boolean_attributes => false,
:compress_js_templates => false
}Htmlcompressor also ships a rack middleware that can be used with rails, sinatra or rack. However keep in mind that compression is slow (especially when also compressing javascript or css) and can negatively impact the performance of your website. Take your measurements and adopt a different strategy if necessary Using rack middleware (in rails) is as easy as: config.middleware.use HtmlCompressor::Rack, optionsAnd in sinatra: use HtmlCompressor::Rack, optionsThe middleware uses a little more aggressive options by default: options = {
:enabled => true,
:remove_multi_spaces => true,
:remove_comments => true,
:remove_intertag_spaces => false,
:remove_quotes => true,
:compress_css => false,
:compress_javascript => false,
:simple_doctype => false,
:remove_script_attributes => true,
:remove_style_attributes => true,
:remove_link_attributes => true,
:remove_form_attributes => false,
:remove_input_attributes => true,
:remove_javascript_protocol => true,
:remove_http_protocol => false,
:remove_https_protocol => false,
:preserve_line_breaks => false,
:simple_boolean_attributes => true
}Rails 2.3 users may need to add require 'htmlcompressor'Javascript template compressionYou can compress javascript templates that are present in the html.
Setting the Custom preservation rulesIf you need to define custom preservation rules, you can list regular expressions in the options = {
:preserve_patterns => [/<\?php.*?\?>/im]
}CSS and JavaScript CompressionBy default CSS/JS compression is disabled.
In order to minify in page javascript and css, you need to supply a compressor in the options hash.
A compressor can be class MyCompressor
def compress(source)
return 'minified'
end
end
options = {
:compress_css => true,
:css_compressor => MyCompressor.new,
:compress_javascript => true,
:javascript_compressor => MyCompressor.new
}Please note that in order to use yui or closure compilers you need to manually add them to the Gemfile gem 'yui-compressor'
...
options = {
:compress_javascript => true,
:javascript_compressor => :yui,
:compress_css => true,
:css_compressor => :yui
}gem 'closure-compiler'
...
options = {
:compress_javascript => true,
:javascript_compressor => :closure
