      oh it’s getting really close! I don’t fully understand everything I am doing. But here’s what I’ve got so far. I’va added these lines:

        <association userDefinedLangName="BR! Source" id="brs_function"/>
      

      and

      		<parser id="brs_function" displayName="BR! Source">
      			<function mainExpr="([0-9][0-9][0-9][0-9][0-9][ ]|)(def|DEF) [\w]+(\(.*\)|)" displayMode="$className->$functionName">
      			</function>
      		</parser>
      

      It encounters the first function in the program then and doesn’t stop… it thinks the rest of the program is a function. I need it to stop at the first “)”, “!” or CRLF (whichever of the three comes first) … I might have formatted my parser stuff wrong too… I didn’t know what to do with the <functionName> section so i just took it out… may have been a bad idea.

        a little more clarification:

        the function definition will always be on one line. the name ends at the first = or (. the variables passed to it (if any) start at the ( and end at the ) and are comma or semicolon delimited. (variables may include characters: a-z,A-Z,_,$,1-9 and &)

        another kink:

        the function definition line may or may not have the word “library” after the def before the function name. for example:

        examples:

        def library fnsteve
        def fnsteve
        def fnsteve(; x,y)
        DEF LIBRARY FNSTEVE( x; y,e3$)
        Def Fnsteve=13
        Def Fnsteve=x12+rnd
        01020 def library fnsteve
        01030 def fnsteve
        01040 def fnsteve(; x,y)
        01080 DEF LIBRARY FNSTEVE( x; y,e3$)
        01022 Def Fnsteve=13
        41020 Def Fnsteve=x
        12+rnd

        In all of these fnsteve would be the function name. In some of these variables passed are like x, y and e3$.

          Try this one:
          ([0-9][0-9][0-9][0-9][0-9][ ]|)(def|DEF)( library| LIBRARY|) [\w]+(\(.*\)|=.+|)

            Closer still!!

            That works beautifully until it encounters a ; then it puts everything on the same line… And also I failed to mention * may be in the variable parameter list… here is a better test list:

            def fnwhatever (x,y,x)
            fnend
            def fn_another
            fnend
            def fnyeah$(nope)
            fnend
            100 def fnyop
            200 fnend
            300 def fnok
            def library fnwhatever (x,y,x)
            fnend
            def library fn_another
            fnend
            def library fnyeah$(nope)
            fnend
            100 def library fnyop
            200 fnend
            300 def library fnok
            def library fnsteve
            def fnsteve

            def fntestastrisk(x$*20,big$*2048)

            def fnsteve(; x,y)
            DEF LIBRARY FNSTEVE( x; y,e3$)
            Def Fnsteve=13
            Def Fnsteve=x12+rnd
            01020 def library fnsteve
            01030 def fnsteve
            01040 def fnsteve(; x,y)
            01080 DEF LIBRARY FNSTEVE( x; y,e3$)

              oh geeze I forgot the &s. & may preceed any or all variables in the line. it’s allowed.

              i.e.

              def fnwhatever(x; &no,more, &spaceallowed)

                A screenshot will explain everything.

                  Otherwise, you can try this one:
                  ([0-9][0-9][0-9][0-9][0-9][ ]|)(def|DEF)( library| LIBRARY|) \w+\$?[ ]*(\(.*\)|=.+|)

                    Alternative:
                    (?i)(\d{3,5}[\t ]+)?DEF([\t ]+LIBRARY)?[\t ]+FN\w+\$?[\t ]*(\([^)]*\)|=)?

                      @donho yours was really close but it was adding everything to the end of the first line when it encounterd a $ for some reason.

                      @MAPJe71 WORKS GREAT!!!

                      I now have all my function lines listed in my Function List! Wonderful - I can double click on them and get right to them! SPECTACULAR!

                      So - one follow detail though - Is it possible for me to get the parameters as auto-complete things when typing code?

                      Here is what I have right now:

                      		<parser id="brs_function" displayName="BR! Source">
                      			<function mainExpr="(?i)(\d{3,5}[\t ]+)?DEF([\t ]+LIBRARY)?[\t ]+FN\w+\$?[\t ]*(\([^)]*\)|=)?" displayMode="$className->$functionName">
                      			</function>
                      		</parser>
                      

                      I notice most the other parser sections have a <functionName> part too - but I don’t… I’m really REALLY happy with what I have right now - but if I can take it a step farther I don’t want to miss out on all the fun =)

                        The Function List parsers are used to populate the Function List tree view only.
                        Auto-Complete has its separate configuration files in the Plugins\APIs sub-folder, but I don’t know if it works for user defined languages. You could try by adding the applicable brs.xml.

                        The <functionName> part is used to filter/resolve the function name e.g.

                        <functionName>
                            <nameExpr expr="(?i)FN\w+\$?[\t ]*(\([^)]*\))?" />
                            <!-- comment out the following node to display the method with its parameters -->
                            <nameExpr expr="(?i)FN\w+\$?" />
                        </functionName>

                          you are correct. and yes, it does work with the UDLs. I have that working, but was only asking if I could use the cool regex syntax detecting settings in functionList.xml to accomplish the same thing. Perhaps I could do it more auto-magically over in there, but that is a subject for another thread. I’m going mark this bad boy solved. THANK YOU!!!
