I need to write a custom syntax for a template engine.

Like this:

https://github.com/pietbrauer/cocoapods-generate-command/blob/master/README.md

Example from the README:

# template
git :init

# questions
prefix = ask('What prefix should be used for your files?')
prefix = prefix.uppercase

# add pods
pod 'AFNetworking', '~> 2.0.0'

pod_group :SampleTests do
  pod 'OCMock'
end

Whats the best approach for this? Would one write a custom DSL or a parser to execute ruby code.

Answer 1

For the example you posted, I'd definitely look at writing an internal Ruby DSL. The syntax looks like valid Ruby code to me, it'll be as easy as it gets.
