When saving a ruby source file that resides in a project, eclim will update that source file in Eclipse and will report any validation errors found. Any errors will be placed in the current window’s location list (:help location-list) and the corresponding lines in the source file will be marked via Vim’s :sign functionality with ‘>>’ markers in the left margin.
Automatic validation of ruby source files can be disabled via the g:EclimRubyValidate variable (described below). If you choose to disable automatic validation, you can still use the :Validate command to manually validate the current file.
Note
This feature depends on the eclipse dltk ruby plugin which should be installed for you when choosing ruby support in the eclim installer.
