Syntax Colouring

R←200⌶Y

This function obtains syntax colouring information for a function.

Y is a vector of character vectors containing the ⎕NR representation of a function or operator.

R is a vector of integer vectors with the same shape and structure of Y in which each number identifies the syntax colour element associated with the corresponding character in Y.

      ∇foo∇
     ∇ foo;local
[1]    global
[2]    local←⍴⍴'hello'
     ∇
      ⎕NR 'foo'
  foo;local   global   local←⍴⍴'hello' 
 
     {(↑⍵),↑200⌶⍵}⎕NR 'foo'
 foo;local       3 21 21 21 19 34 34 34 34 34 0 0 0 0 0 0
 global          3  7  7  7  7  7  7  0  0  0 0 0 0 0 0 0
 local←⍴⍴'hello' 3 34 34 34 34 34 19 23 23  4 4 4 4 4 4 4

In this example:

21	is the syntax identifier for "character constant"
19	is the syntax identifier for "primitive"
3	is the syntax identifier for "white space"
34	is the syntax identifier for "local name"
7	is the syntax identifier for "global name"
23	is the syntax identifier for "idiom"

The list of syntax colour elements supported by the current interpreter is given by 201⌶. It is important to note that the values may change within a release, and are very likely to change across releases .. you should always call 201⌶ rather than relying the results from a different interpreter.
