Ioke Syntax Highlighter for GeSHi

January 10, 2009, 00:53

Speaking of Ioke – just added a syntax highlighter definition for GeSHi in my Ioke fork repository. The commit can be found here:

http://github.com/melwin/ioke/commit/54cfd7e54de0be910385c6ec805693fd3ed4e294

The keyword definitions I borrowed (read stole) from Sam Aaron’s TextMate bundle (also in the Ioke repository). As Sam just said in the #ioke on freenode: “what goes around comes around”. :)

Highlighting test:

    m = #/({areaCode}\d{3})-({localNumber}\d{5})/ =~ number
 
    describe("start",
      it("should return the start index of group zero, which is the whole group",
        (#/foo/ =~ "foobar") start should == 0
        (#/foo/ =~ "abcfoobar") start should == 3
 
        (#/foo/ =~ "foobar") start(0) should == 0
        (#/foo/ =~ "abcfoobar") start(0) should == 3
      )
 
      it("should return the start index of another group",
        (#/(..) (..) (..)/ =~ "fooab cd efbar") start(2) should == 6
      )
 
      it("should return the start index from the name of a named group",
        (#/({one}..) ({two}..) ({three}..)/ =~ "fooab cd efbar") start(:two) should == 6
      )
 
      it("should return -1 for a group that wasn't matched",
        (#/(..)((..))?/ =~ "ab") start(2) should == -1
        (#/({no}..)(({way}..))?/ =~ "ab") start(:way) should == -1
 
        (#/(..)((..))?/ =~ "ab") start(10) should == -1
        (#/({no}..)(({way}..))?/ =~ "ab") start(:blarg) should == -1
      )
 
      it("should validate type of receiver",
        Regexp Match should checkReceiverTypeOn(:start)
      )
    )
 
    x = #/bla #{"foo"} bar/

Scala Syntax Highlighting for WP

June 30, 2008, 09:56

Writing the previous post I realized that the Wordpress plugin for syntax highligting I was using (Highlight Source Pro) didn’t support Scala.

Instead I tried the WP-Syntax plugin, but this didn’t support Symbol literals:

val sym = 'foobar
println("Symbol is: " + sym)
val other = 'barfoo

This seems to be because of single quote being interpreted as a quotation character. A fix seems to be removing the single quote from the Geshi language definition file scala.php in the wp-syntax/geshi/geshi directory. While there one can also specify a regex for symbols and give them their own color:

val sym = 'foobar
println("Symbol is: " + sym)
val other = 'barfoo

Also check out the scala.php in the LAMP repository – it seems to add some additional keywords and other colors. I used this and made the changes described above.

Full new scala.php for Geshi after the break.
