and here is my source code :

let boatGenO () =

		let isPlaced = ref false in
		while not !isPlaced do
			if (Random.bool()) then begin
				let x = Random.int (10-length) and
					y = Random.int 10 in
				let canBePlaced = ref true in
				for i=0 to pred length do
					if plateauO.(x+i).(y)<>" " then canBePlaced := false;
				done;
				if !canBePlaced then begin
					for d=0 to pred length do
						plateauO.(x+d).(y) <- (boatSymbol.(boat));
					done;
					tabBateauO := Array.concat [!tabBateauO; [|(x, y, (boat, false), 1)|]];
					isPlaced := true;
				end;
			end else begin
				let y = Random.int (10-length) and
					x = Random.int 10 in
				let canBePlaced = ref true in
				for i=0 to pred length do
					if plateauO.(x).(y+i)<>" " then canBePlaced := false;

					tabBateauO := Array.concat [!tabBateauO; [|(x, y, (boat, false), 0)|]];

				end;

	done;
	Array.iter (fun ligne -> begin
		print_string "|";
		Array.iter (fun symb -> print_string (symb^"|");) ligne;
		print_string "\n";
		end;) plateauO;
in

I expected that only boatGenO matchs but it’s not the case and I can’t figure out why.

Wasn’t obvious to me

That’s fine, we all have different levels of experience with computers in general. I hope you didn’t spend a lot of time thinking your expressions must be wrong if the right stuff didn’t happen right when you saved the xml file!

Later thought: Actually, I don’t know what the refresh button in the Function List window does. For all I know it may do what you originally thought and something else was wrong?

Maybe you have you have to restart NPP to refresh the functionList rules

Yes! If you manually-edit any of Notepad++'s configuration files (and for functionList.xml that is the only way), changes aren’t going to be picked up until you restart Notepad++. I really think this is obvious, even if you aren’t all that familiar with Notepad++.

And FYI, be careful when manually editing other config files, because upon shutdown Notepad++ may need to overwrite them with its own changes, blowing away any manual edits you may have done.

Problem solved with @guy038’s method making a backup of the Notepad++ folder in AppData and delenting this one. Maybe you have you have to restart NPP to refresh the functionList rules. I don’t know why, but it was as if it kept the old functionList.xml even if I had modified it. Weird… Now, I will improve the regex selector, I will share here the code for those who are interested.

Merci à toi @guy038, j’ai fait exactement ce que tu m’as dit et ça a marché. J’avoue que je réchignais un peu à faire ça car j’avais pas mal customisé NPP mais j’ai juste à copier-coller le contenu donc aucun problème. ^^

La fois dernière, j’avais simplement ouvert un nouvel onglet copié ton exemple CAML et choisi the langage Caml pour tester ma solution.

Cette fois, j’ai copié ton code Caml dans un fichier, nommé test.ml, et, une fois encore, les résultats étaient corects. Dans la fenêtre de Function List, les 4 fonctions n, amis, ncadeau et cadeau étaient bien présentes !

Personnellement, j’utilise N++ v7.5.8, en configuration locale, placé dans le répertoire D:\@@\758 => Tous les fichiers de configuration se trouvent dans ce dossier ou les ses sous-dossiers :-))

Si j’étais toi, je testerai la méthode de Scott mais si tu as un peu peur de faire des bêtises, tu peux simplement renommer un des deux fichiers functionList.xml, disons : functionList.tom et de faire le test ( A propos, c’est chouette, d’avoir un prénom de trois lettres comme toi et moi, pour changer l’extension d’un fichier ! )

Je pense que tu as installé N++ de manière traditionnelle, avec l’“Installer”. Dans ce cas, le fichier, du répertoire C:\Program files\Notepad++, n’est sûrement pas utilisé !

Maintenant, je te conseille, également, de renommer le répertoire AppData\Roaming\Notepad++ en AppData\Roaming\Old_N++ ( bien sûr, après avoir fermé toutes les instances de N++ ouvertes ! )

A la prochaine ouverture de N++, une nouvelle arborescence de travail AppData\Roaming\Notepad++ devrait être créée, avec les sous-répertoires adéquats. Tu verras bien si FunctionList fonctionne, cette fois !

Si ce n’est pas mieux ( ou même pire !), tu pourras toujours renommer AppData\Roaming\Old_N++ en AppData\Roaming\Notepad++. Rien ne sera perdu ;-))

A+ ( For non-French speakers, it’s a very-common shortcut of the French expression “À plus tard”, which could be translated as “See you later” ! )

Only ONE functionList.xml file will matter for you.

Do this: Select ? (menu) -> Debug Info… and read the result.

If Local Conf mode is ON, then the active functionList.xml (and other configuration files) will be in the same folder as notepad++.exe

If Local Conf mode is OFF, then the active functionList.xml (and other configuration files) will be in %APPDATA%\Notepad++

As I say, my problem is not with the regex but how do you change the functionList.xml in order to implement a new language parser. As you said, I already included the assiociation map. That’s why I don’t know where the problem could be 'cause there is a problem : it doesn’t work at all with a .ml file. Nothing is displayed as if it doesn’t know there is a new parser.
Do you think I did not install NPP well ? Is it normal to have two functionList.xml files which are not related or linked ? One is in AppData\Roaming\Notepad++ and the other one is in Program files\Notepad++

Thanks you 2 for helping me
(Tu peux parler en français, je le suis ^^).

I thougt the main rexpression regex of Tom, terribly complicated !! I’m probably missing some particularities but my solution works nice with the sample file , provided by Tom. Of course, it needs some testing on true CAML files !

Here is my first ( simple ) attempt :

			<association id=      "caml_syntax"       langID="41"                          />
		</associationMap>

		<parsers>

			<parser
				displayName="Caml"
				id         ="caml_syntax"
				commentExpr="\(\*((?!\(\*|\*\)).)+?\*)$"
			>
				<function
					mainExpr="let\s+(rec \s+)?[\l_]\w*\s*?=.+?in$"
				>
					<functionName>
						<nameExpr expr="let\s+(rec \s+)?\K[\l_]\w*"
						/>
					</functionName>
				</function>
			</parser>

Note that I included the line <association id= "caml_syntax" langID="41" in the associationMap node

Cheers,

guy038

• read_int
• n
• amis
• nCadeau
• cadeau

It’s what it should look like with my actual RE, it detects one function/variable per ‘let’ key word.
It’s not the ideal thing but it’s just a start. I would like it can detect ‘and’ key word which allows to define several variables with 1 ‘let’.
But first, I just want the base works to improve the code. And it doesn’t with no reason to me…

I don’t know why, but I’ve got two different files named functionList.xml, one in AppData\Roaming\Notepad++ and one in Program Files\Notepad++
So I modified both of them but still nothing appears in function list pannel when I open a OCaml source code.

I’m loosing hope…
Here is a OCaml source code for anyone who wants to clearify it (tell me if there is a way to collapse it) :

let read_int () = Scanf.scanf " %d" (fun x -> x) in

let n = read_int() and
	m = read_int() in
let amis = Array.init n (fun x -> pred (read_int())) and
	guir = Array.init n (fun x -> read_int()) in

let nCadeau = ref 0 and
	positions = ref [] and
	nb = ref 0 in

try
	while nb <  do
		incr nb;
		let cadeau = ref true in
		try
			for i=pred n downto 1 do
				if (guir.(amis.(pred i)) > guir.(amis.(i))) then begin
					cadeau := false;
					(* Printf.printf "guir.(%d) > guir.(%d)\n" (amis.(pred i) + pos) (amis.(i) + pos); *)
					raise Exit;
				end;
				(* Printf.printf "guir.(%d) < guir.(%d)\n" (amis.(pred i) + pos) (amis.(i) + pos) *) (*DEBUG*)
			done;
			if (!cadeau) then begin
			incr nCadeau;
			positions := !positions @ [n];
		end;
		with
			| Exit -> begin () end;
		for i=0 to n-2 do
			guir.(i) <- guir.(succ i);
		done;
		guir.(pred n) <- read_int();
	done;
with
	| Invalid_argument "end of file" -> ();

Printf.printf "%d\n" (!nCadeau);
List.iter (fun x -> Printf.printf "%d " x;) (!positions);

I don’t see anything that could help me with your link.

Do you agree that to modify the function parser of a language or just implement it, you only have to change the functionList.xml file, save changes and refresh NPP, don’t you ?

If yes, then it means that my code may contain some errors 'cause it doesn’t work at all.
