How to extend "Execute in block" feature?

[leakyMirror]

I love r-box and I use with many other languages (because it works). However "execute in block" feature does not work in languages where function is defined without {}. Is it hard to make it work with this kind of syntax?:

function foo() 
  a = 1
  b = 2
  return a + b
end

I read the code and found that it uses a fancy regex to grab functions. So decided to ask you for an advice before diving deeper.

Thanks.

It depends on the language itself.

PS: is it julia?

[leakyMirror]

Yes it is :)

I have been thinking to write a general package which extends SendText to what R-Box could do. But the "block" feature really depends on the language itself.

Perhaps, I can write a simple plugin for julia, e.g. Julia-Box....

It would be awesome. Isnt it require just to change that regex? Everything else is working, as far as I know

Julia is bit tricky, there are at least the following things to consider

1. control flow: for, while, if else etc..
2. string "foo"
3. command echo $HOME
4. @begin @end, quote end
5. comment, both # and block comment #= =#
6. .....others

I am thinking only about function and maybe for, if and while.

These ussualy are the biggest blocks in the code. It is anoying to execute them line by line.

[randy3k]

it is necessary to consider all these, for example

function f(x)
   # end
   a = "end"
   b = @begin
   1+ 1
   @end
   if 1 > 2
      b = 2
   end
   b
end

If you don't consider them, we will not be able to find the last end.

What about matching the indetation? For example if there are 4 space before function you need to search for first end with 4 spaces.
