      Hi John,

      User Defined Language doesn’t support (yet) regex.
      So in your cas, you can only colourise def (or DEF).

      I’ll do a feature request to Loreia (the person who develops and maintains UDL), but it will not be soon even the FR is accepted.

        Oh - I’m not trying to colorize it. I’m trying to make them appear in the functionlist side bar. :)

          Oups sorry, I misunderstand you totally.

          Each function takes only one line and whole line?

            John,

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

              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$.

                    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!!!
