live template like TextMate

创建于 2010年04月12日 23:06

hello,

  I am trying to convert some snippets from TextMate and I am having some trouble with a controller action. What I would like to have is this:

def create
  @model_name = ModelName.new
end

  When I type "model_name" I would like RM to fill out the ModelName.

Regards,
Cezar

I know one way, but you need to take a look on Groovy language =)

1. Create Live template with text

def create
@$MODEL_VAR_NAME$ = $MODEL_CLASS$.new
end

2. Select "Ruby" context checkbox
3. Press "Edit variables" button
4. Now you need to specify expression(function) which will automatically modify MODEL_CLASS variable using MODEL_VAR_NAME value. If you put cursor in "expression" field you will notice several predefined functions. Unfortunately you will not find "to_camel_case" function ( you can submit a request in our bugtracker). But there is one universal function - ability to execute any Groovy script.
5. So you need to specify something like this

groovyScript("_1.toUpperCase()", MODEL_VAR_NAME)

First parameter is Groovy script body or path to Groovy script file on disc.
Second and other params will be bind to '''_i''' groovy local variable, i from [1, 2, ..].

The script from my example converts MODEL_VAR_NAME to upper case. If you wan't CamelCase - please write corresponding groovy script by yourself. Sorry =)

6. Also select checkbox "skip if defined" for MODEL_CLASS variable.

can you provide some info on what subset of groovy works inside RM ? I've tried a few methods but none of them seemed to work so I need some docs for the groovy lang, thanks
