Request for language support, four variants: PEG, peg.js, peggy, tspeg

[StoneCypher]

Main language

• language name: PEG
• file extension(s): .peg
• method(s) of commenting text: c/c++ style - line comments with //, non-nesting block comments with /* */
• location of sample code: below. Also,
  • here
  • here

Expression
  = head:Term tail:(_ ("+" / "-") _ Term)* {
      return tail.reduce(function(result, element) {
        if (element[1] === "+") { return result + element[3]; }
        if (element[1] === "-") { return result - element[3]; }
      }, head);
    }

Term
  = head:Factor tail:(_ ("*" / "/") _ Factor)* {
      return tail.reduce(function(result, element) {
        if (element[1] === "*") { return result * element[3]; }
        if (element[1] === "/") { return result / element[3]; }
      }, head);
    }

Factor
  = "(" _ expr:Expression _ ")" { return expr; }
  / Integer

Integer "integer"
  = _ [0-9]+ { return parseInt(text(), 10); }

_ "whitespace"
  = [ \t\n\r]*

Variant language 1

• language name: peg.js
• file extension(s): .pegjs

Variant language 2

• language name: peggy
• file extension(s): .peggy

Variant language 3

• language name: tspeg
• file extension(s): .tspeg, .jspeg

Please give 04dcf36 a quick try before I release 1.94.

The four languages I'm involved with look good to me

Really surprising to see perl there - I thought this was written in perl?

[StoneCypher]

Notably, the part of the SDP parser you took, while valid, isn't normative PEG; the "normal" part is in the cut off part past the truncation

If you want a short example you're probably better off with the arithmetic example from this issue

[StoneCypher]

The part in the actual code examples is fine though

[StoneCypher]

As far as giving it a try, I don't actually know how to install CLOC without using the npm wrapper I've been using

Do I pop it from CPAN? If so, how, please? I'm not a perl person

[AlDanial]

To run cloc using its Perl source code on Windows instead of the .exe, you'll need to install a Perl interpreter for Windows. I use Strawberry Perl. Then you can do, for example, C:> perl cloc my_source_dir

Regarding the SDP parser fragments I copied for testing, the stuff I extracted doesn't need to be real PEG code, just something representative of what PEG might look like.

Appears to work

Confirmed working in my stack. Thank you
