如何在我的
ruby代码中调用指南针来编译项目而不调用shell命令?
我尝试从Using Compass from Ruby (not shell)调整解决方案,但没有成功.我的项目结构看起来像
assets/scss (location of uncompiled project files) assets/css (location for compiled css) assets/compass/config.cfg (the compass config file)
我尝试过这样的事情
fixed_options = { :project_path => '/path/to/assets,:sass_path => 'scss',:css_path => 'css' } Compass.add_project_configuration '/path/to/assets/compass/config.rb' Compass.add_configuration fixed_options,'custom' Compass.compiler.run
这是有效的,但是只有在项目root / path / to / assets中运行irb时才会这样做.
似乎在fixed_options中设置的任何内容都会根据需要覆盖config.rb中的选项(或者它们被合并,或者有两组选项:我有点难以告诉),但是:project_path似乎没有做任何事情因为指南针似乎只关心我运行的目录.
注意:我一直在尝试使用irb中Compass.compiler的输出来尝试了解正在发生的事情.
解决方法
注意:这可能不是您想要的答案,因为它涉及shell,但它可能是您想要的答案,因为它涉及从shell运行一次命令,然后在资产更改时重新编译.也许这对你来说已经足够了.
这是我的Gemfile的相关部分(我正在使用OSX):
# Gems used only for assets and not required # in production environments by default. group :assets do gem "sass" # sassy CSS gem "coffee-script" # destroy javascript! gem "guard" # file watcher with rules gem "guard-coffeescript" # regen coffee gem "guard-sass",:require => false # auto generate sass gem "rb-fsevent" gem "growl" # notifications for OSX end
Compass配置文件:
# Set this to the root of your project when deployed: http_path = "/" css_dir = "public/css" sass_dir = "views/stylesheets" images_dir = "public/images" javascripts_dir = "public/js" project_type = :stand_alone output_style = :compact line_comments = false preferred_Syntax = "scss"
在./Guardfile中
# This will generate stuff: guard 'coffeescript',:input => "coffee",:output => 'app/public/js' guard 'sass',:input => 'app/views/stylesheets',:output => 'app/public/css',:compass => true,:style => "compressed",:shallow => true
然后我在终端中运行guard start,它将查看文件以进行更改并重新编译更改.我让终端窗口在后台打开,所以我也可以强制重新编译.因人而异.
