      @PeterJones thanks for the help

      i should of mentioned my file is ext .cpp Just like C++ file, its a software that uses C++ but they built an API off of C++ so the extension file is .cpp

      i have copied your code and cannot get it to return the functions. I can go to an online Regex playground and return the Class and functions, but when i try and translate it into the FunctionList.xml it fails

      <NotepadPlus>
      <functionList>

          @JR said in FunctionList help:

          i have copied your code and cannot get it to return the functions. I can go to an online Regex playground and return the Class and functions, but when i try and translate it into the FunctionList.xml it fails

          For the FUNCTION only version:

          I have grabbed a fresh copy of NPP.v7.8.9-64 and unzipped to a known location, and started from there.
          I defined a UDL called “SierraChart” with extension .cpp:
          4c90e185-c3a0-40ad-b836-744979c51d54-image.png

          When I add the <association entries and <parser entry in the appropriate locations, it works for me as I would expect for functions only:
          42992368-a181-4f8f-9242-7b310a488d95-image.png

          Please note that in the code you posted for the FUNCTION-only version, you did not have the <parser ...> entry inside of the <parsers> tag: I don’t know if that was real, or a result of your pruning for the forum. My excerpt can be seen in the screenshot, and here is a direct copy paste, where there is stuff before and after, but everything shown is exactly contiguous:

          <association id="SierraChart"  userDefinedLangName="SierraChart" />
          <association id="SierraChart"  ext=".cpp"                        />
          		</associationMap>
          		<parsers>
          <parser id="SierraChart" displayName="SierraChart">
          	<function mainExpr="//reg @\w+">
          		<functionName>
          			<nameExpr expr="(?<=//reg @)\w+" />
          		</functionName>
          	</function>
          </parser>
          

          Please remember that after you make changes to functionList.xml, you have to exit Notepad++ and reload for it to take effect.

          I will try to experiment with the classes next.

            @JR ,

            At first glance, in your CLASS-enabled, I found two bugs

            1. It’s also not showing the <parsers>... open tag. Again, that might just be your editing
            2. The <association...> lines both use SierraCharts (with an s at the end), whereas your first example, and your claim about your UDL, use just SierraChart (with no s). It will not work unless the userDefinedLang name exactly matches the UDL name, and the <parser id exactly matches the <association id.

            I will continue to explore, correcting those two bugs.

              Continuing, using the example code functionlist.cpp:

              /* not in any class */
              //reg @unclassedFunction
              <code to process>
              //end
              
              SCSFExport scsf_ClassNameExample(SCStudyInterfaceRef sc)
              
              //reg @chartSettings
              <code to process>
              //end
              
              //reg @defaultSettings
              <code to process>
              //end
              
              //reg @Create_NewOrders
              <code to process>
              //end
              
              SCSFExport scsf_AnotherClassName(SCStudyInterfaceRef sc)
              
              //reg @BuyOrders
              <code to process>
              //end
              //reg @SellOrders
              <code to process>
              //end
              

              When I use your regular expression for the class section, (^SCSFExport) ([\s\S]+\n?) (?=SCSFExport), in the normal Find dialog, I get 0 matches in my example code:
              5194ed74-3e67-446a-82cd-e9cb6fca0a53-image.png

              If I tweak that to (?s)(^SCSFExport)(.+?)(?=SCSFExport|\Z), I get two matches, as I would expect. And if I highlight them, they do what I expect.

              However, when I plug that into the functionList.xml and restart,

              <association id="SierraChart"  userDefinedLangName="SierraChart" />
              <association id="SierraChart"  ext=".cpp"                        />
              		</associationMap>
              		<parsers>
              <parser id="SierraChart" displayName="SierraChart">
              	<classRange mainExpr="(?s)(^SCSFExport)(.+?)(?=SCSFExport|\Z)">
              		<className>
              			<nameExpr expr="^SCSFExport +\K(\w+)" />
              		</className>
              		<function mainExpr="//reg @\w+">
              			<funcNameExpr expr="(?<=//reg @)\w+" />
              		</function>
              	</classRange>
              	<function mainExpr="//reg @\w+">
              		<functionName>
              			<nameExpr expr="(?<=//reg @)\w+" />
              		</functionName>
              	</function>
              </parser>
              

              my function list only showed the one unclassedFunction, and didn’t find any of the functions inside classes (in the screenshot above)

              I’m not sure why it’s not finding the class names or functions within those classes.

              Sorry.

                @PeterJones thanks Peter. ill look into your posts this weekend and see what i can get done. I found a “regex playground” specific to Boost (which allegedly is the Regex engine for NPP). here is a link to the software. its a free download

                http://zett42.de/software/boost-regex-playground/

                  @PeterJones thanks for taking the time…

                  here is a pic of just the classes. using the BoostRegex playground software it captures both areas of classes, then specifically the class names.

                  i also cant get it to work (i fixed the userLang issue, also i kept only the classes to test, removed any function expr.)

                    Hello @JR, @Peterjones, @alan-kilborn and All,

                    Thank you, @JR, to let us discover Boost Regex Playground v1.1, a regular expression tester, specific to the Boost library :-))

                    After some tests, here are some notes, in any order :

                    • Boost Regex Playground v1.1 uses the Boost library with documentation version 1.50. But since its v7.7 version, Notepad++ uses an updated version : the Boost documentation 1.70, which allow, for instance, the use of backtracking control verbs, like (*FAIL) or (*PRUNE), not taken in account by the Boost Regex Playground v1.1 software !

                    • By default, this software uses the mod_s flag, so the in-line modifier (?s). Generally, in order that any dot char represents a single standard character only, two possibilities :

                      • Use the in-line modifier (?-s) in the regex

                      • Tick the no_mod_s flag

                    • As examples, try the regexes, below :

                      • a a # aa with the flag mod_x [ (?x) ] or without

                      • ^[a\x20\#r\n]*?$ with the flag no_mod_m [ (?-m) ] or without

                      • ^.* with the flag no_mod_s [ (?-s) ] or without

                    Against this TWO-lines text :

                    aaaaaaaaaaaaaa     a # aaaaaaaaaa
                    aaaaaa          aaaaaaaa
                    
                    • It’s also worth to note that :

                      • By clicking on the ... marker, you can modify the size of any sub-windows

                      • After clicking inside any sub-windows, you can zoom in or out each sub-window, by hitting the Ctrl key and moving the mouse wheel, up or down

                    • The match flags format_no_copy and format_first_only may be interesting, too, in replacements

                    Best Regards,

                    guy038

                      Hi, @JR, @Peterjones, @alan-kilborn and All,

                      While testing the regex tester software, provided by @JR, I wanted to verify if it knew the \x{hhhhh} syntax in order to search any character with code-point over \x{FFFF} as I know that the N++ Boost regex engine does not know this one :-((

                      Unfortunately, it does not know this syntax, as well ! But, then, I remembered that Notepad++ can use the surrogates mechanism, to search for all characters which lie outside the Basic Multilingual Plane ( BMP ) ! And the Boost Regex Playground software, too !


                      For a full explanation about the two 16-bits code units, called a surrogates pair, refer to :

                      https://en.wikipedia.org/wiki/UTF-16#Code_points_from_U+010000_to_U+10FFFF

                      For the calculus of the surrogates pair of a specific character, refer, either , to :

                      http://www.russellcottrell.com/greek/utilities/SurrogatePairCalculator.htm

                      http://www.cogsci.ed.ac.uk/~richard/utf-8.cgi?

                      The surrogate pair of a character, with code-point in range from \x{10000} till \x{10FFFF}, can be described by the regex :

                      \x{hhhh}\x{iiii}    where D800 < hhhh < DBFF    and    DC00 < iiii < DFFF

                      For instance, the pictograph 🧀 ( A cheese wedge ), of code-point \x{1F9C0} cannot be searched with this syntax. As its surrogates pair is D83E + DDC0, we can searched this specific character from within N++, with the regex syntax \x{D83E}\x{DDC0}

                      If we use the free-spacing mode, for a better visibility, we may note that two syntaxes, only, are correct !

                      (?x) [\x{D83E}] [\x{DDC0}]  #  Wrong   syntax
                      (?x) [\x{D83E}]  \x{DDC0}   #  Wrong   syntax
                      (?x)  \x{D83E}  [\x{DDC0}]  #  CORRECT syntax
                      (?x)  \x{D83E}   \x{DDC0}   #  CORRECT syntax
                      

                      In order to match any character outside the BMP, use one of the two general syntaxes, below :

                      • .[\x{DC00}-\x{DFFF}]    which begins with a dot symbol

                      • [^\x{0000}-\x{D7FF}\x{E000}-\x{FFFF}]    as the surrogates zone lies between \xD800 and \xDFFF

                      Strangely, the more rigorous syntax (?x) [\x{D800}-\x{DBFF}] [\x{DC00}-\x{DFFF}] does not work !?

                      You may get some additional information, consulting these two posts :

                      https://community.notepad-plus-plus.org/post/51068

                      https://community.notepad-plus-plus.org/post/43037


                      So I said to myself : Is there a way to get, for instance, the surrogates syntax \x{D83E}\x{DDC0} from the \x{1F9C0} syntax ? Yes, there a method, described in the Wikipedia article, which may be solved with 4 consecutive regex S/R ! And the good news is that I succeeded to gather these 4 regex S/R in an unique macro, described, below ;-))

                      Example :

                      The string 𝅘𝅥𝅮 — 🧀, in theory, could be searched with the regex \x{1D160}\x20\x{2014}\x20\x{1F9C0}. ( BTW, the \x{2014} represents the EM DASH character — ! )

                      So, starting with the regex \x{1D160}\x20\x{2014}\x20\x{1F9C0} :

                      In the first regex S/R, we identify, exclusively, the syntaxes from \x{10000} till \x{10ffff}, adding the C1-Control code \x1F, after each code-point > \x{FFFF}

                      => \x{1D160}\x20\x{2014}\x20\x{1F9C0}

                      IMPORTANT : This control code \x1F cannot be seen on our site, but is well displayed as the US char, in reverse video, from within Notepad++ !

                      In the second S/R, we rewrite the code-points > \x{FFFF}, in binary, minus the value \x{100000}

                      => \x{00001101000101100000}\x20\x{2014}\x20\x{00001111100111000000}

                      In the third S/R, we rewrite the 20 bytes, of each code-point, in two blocks of 10 bytes, adding the leading parts 110110 and 110111, as described in the Wikipedia article

                      => \x{1101100000110100}\x{1101110101100000}\x20\x{2014}\x20\x{1101100000111110}\x{1101110111000000}

                      In the fourth S/R we reconstitute the surrogates pairs, of each code-point, by conversion of each 16 bytes block, from binary to hexadecimal and we delete of the \x1F temporary character

                      => \x{D834}\x{DD60}\x20\x{2014}\x20\x{D83E}\x{DDC0}


                      The different search and replacement regexes are stored in a macro, below. Just insert it in the <Macros>....</Macros> node of your active shortcut.xml file !

                              <Macro name="Conversion to Surrogates Pairs" Ctrl="no" Alt="no" Shift="no" Key="0">

                      I invented this little text :

                      Here are some pictographs, with code-point over \x{FFFF} : The INITIAL U+10000 char (old Greek syllable) 𐀀 — the roman "siliqua" coin 𐆕 — An eighth note 𝅘𝅥𝅮 — the ace of spades 🂡 — the Earth globe 🌍 — Father Christmas 🎅 — a grinning face 😀 — a round target 🞋 — an upwards heavy arrow 🡅 — a cheese wedge 🧀 — the private-use U+FFFFD char 󿿽 and the FINAL private-use U+10FFFD char 􏿽
                      

                      In theory, the regex :

                      (?-i)Here are some pictographs, with code-point over \\x\{FFFF\} : The INITIAL U\+10000 char \(old Greek syllable\) \x{10000} \x{2014} the roman "siliqua" coin \x{10195} \x{2014} An eighth note \x{1D160} \x{2014} the ace of spades \x{1F0A1} \x{2014} the Earth globe \x{1F30D} \x{2014} Father Christmas \x{1F385} \x{2014} a grinning face \x{1F600} \x{2014} a round target \x{1F78B} \x{2014} an upwards heavy arrow \x{1F845} \x{2014} a cheese wedge \x{1F9C0} \x{2014} the private\-use U\+FFFFD char \x{FFFFD} and the FINAL private\-use U\+10FFFD char \x{10FFFD}

                      should match the text above ! However, as we get the error message FIND: Invalid regular expression. Then :

                      • Select all this initial search regex expression

                      • Run the macro Macros > Conversion to Surrogates Pairs and, at once, the search regex, still selected, is changed as :

                      (?-i)Here are some pictographs, with code-point over \\x\{FFFF\} : The INITIAL U\+10000 char \(old Greek syllable\) \x{D800}\x{DC00} \x{2014} the roman "siliqua" coin \x{D800}\x{DD95} \x{2014} An eighth note \x{D834}\x{DD60} \x{2014} the ace of spades \x{D83C}\x{DCA1} \x{2014} the Earth globe \x{D83C}\x{DF0D} \x{2014} Father Christmas \x{D83C}\x{DF85} \x{2014} a grinning face \x{D83D}\x{DE00} \x{2014} a round target \x{D83D}\x{DF8B} \x{2014} an upwards heavy arrow \x{D83E}\x{DC45} \x{2014} a cheese wedge \x{D83E}\x{DDC0} \x{2014} the private\-use U\+FFFFD char \x{DBBF}\x{DFFD} and the FINAL private\-use U\+10FFFD char \x{DBFF}\x{DFFD}

                      • Select again the search, mark or replace dialog

                      • This time, it should match, as expected, the text above ;-))

                      Notes :

                      • The macro does not change any \xhh, \x{hh} or \x{hhhh} syntaxes, found in the selection

                      • The hexadecimal values can be written, in either upper or lower case !

                      • Of course, you may just want to know the surrogates pair of a specific character \x{hhhhh} by selecting the string \x{hhhhh} and running the Conversion to Surrogates Pairs macro !

                      Best Regards,

                        Hi, all,

                        Arrrrrrh ! My God ! Right after posting, I realized that my nice theory is, most of the time, rather useless :-(

                        Really, using the example, given in my previous post :

                        Here are some pictographs, with code-point over \x{FFFF} : The INITIAL U+10000 char (old Greek syllable) 𐀀 — the roman "siliqua" coin 𐆕 — An eighth note 𝅘𝅥𝅮 — the ace of spades 🂡 — the Earth globe 🌍 — Father Christmas 🎅 — a grinning face 😀 — a round target 🞋 — an upwards heavy arrow 🡅 — a cheese wedge 🧀 — the private-use U+FFFFD char 󿿽 and the FINAL private-use U+10FFFD char 􏿽
                        
                        • Just select all this text

                        • Open the Find dialog ( Ctrl + F )

                        • Choose the Normal search mode

                        • Click on the Find Next button to find any other occurrence of that text !

                        Also, the interest of my demonstration is rather limited, isn’t it?

                        Cheers,

                        guy038

                          So I guess I am confused by this.

                          Just select all this text… (and further instructions)

                          Yes, but isn’t it often the case that you don’t have handy such an exact text you need to search for?

                          Maybe you need to search for a certain character, and all you have is its code. Example, the cheese wedge from before. You may immediately know that it is \x{1F9C0} but that’s all you know and you want to search for it.
