Hi

How can I best parse something recursively?

Use Ruby as DSL, or are there better tools (using another language??)

data := [ parts ] # joined by ','

 parts = <VAR> assignments parts </VAR>    \# part can include part \!\!

 assignment := var=val

 assignments := assignment\{0,n\} \(joined by ','\)

# VAR, var, val are (different) strings for each item.

Thank you

Please take a look at this:

If you want to build an Internal DSL (aka Embedded DSL in Ruby:
InternalDslStyle), Glimmer's DSL Engine
enables building the most flexible yet minimalistic DSLs possible in Ruby:
GitHub - AndyObtiva/glimmer: DSL Framework consisting of a DSL Engine and a Data-Binding Library used in Glimmer DSL for SWT (JRuby Desktop Development GUI Framework), Glimmer DSL for Opal (Pure Ruby Web GUI), Glimmer DSL for LibUI (Prerequisite-Free Ruby Desktop Development GUI Library), Glimmer DSL for Tk (Ruby Tk Desktop Development GUI Library), Glimmer DSL for GTK (Ruby-GNOME Desktop Development GUI Library), Glimmer DSL for XML (& HTML), and Glimmer DSL for CSS

For example, I recently wrote this Pixelart DSL with it in one hour:

DSL Code (just 2 types of expressions):

I also recently wrote this GTK DSL with it in one day:

DSL Code (just 3 types of expressions):

Cheers,
