1: Wobei mir Deine Kommentare fast schon zu nützlich und ausführlich sind.

Das war der Plan. Ich habe die Regel nach Bestem Wissen und Gewissen genau so angewendet wie sie gedacht ist. Trotzdem, oder gerade deswegen, ist das Ergebnis ziemlicher Unfug. So zeigt man, dass die Regel absurd ist, denn das durch die Regelung erhoffte Ergebnis (Nachvollziehbarkeit, Lesbarkeit) wird gerade aufgrund der Regel verfehlt.

@Pale: Falls du nicht nachvollziehen kannst, wieso sich alle über Regel 12 amüsieren: Es gilt als ziemlich schlechter Stil, wenn Code eines Kommentars bedarf. Guter Code ist selbsterklärend, und es sollte die absolute Ausnahme sein, dass man jemals eine Zeile kommentieren muss, um zu erklären, was sie tut. Wenn das öfters nötig ist, ist das ein deutlicher Code-Smell, ein Zeichen für schlechten Code/Programmierung. Kommentare setzt man üblicherweise zur Dokumentation ein, was eine Funktion/Klasse tut und wie sie zu benutzen ist ("Diese Funktion liefert den Sinus des Arguments x"); als Hinweis für andere Programmierer ("Die Längenprüfung hier ist wichtig, sonst bekommt man einen Indexfehler wenn das Suchergebnis leer ist"); oder als allgemeinen Kommentar zu einem Codestück ("Hier wird der Holgensteiner-Clusteringalgorithmus implementiert, wie er in JoCS 24, pp. 456-0487 beschrieben wird").

Denken spreche ich dem Aufgabensteller zumindest für die Zeit der Formulierung von Punkt 12 einfach mal ab. Und falls doch steht nirgends in der Aufgabe, daß es nötig sei zu erraten, welche verkorksten kognitiven Prozesse in dessen Birne liefen. Ich bin immer noch der Meinung, daß mein lückenlos kommentierter Code der Aufgabenstellung voll und ganz genügt.

Ja, aber was willst du dann überhaupt zeigen, wofür der viele Text in diesem Thread hier? Willst du zeigen, dass die Regel doof ist? Das zeigst du so nicht. Du zeigst nur, dass sich jemand (=du) genügend doof stellen kann, um die Anweisungen falsch zu verstehen. Das lässt aber nur dich doof aussehen, weil du eine einfache, klare Regel absichtlich nicht wie gedacht anwendest und somit ungeeignet für die Vergabe des Auftrags bist.

Ich habe doch schon längst gezeigt, dass man selbst unter gutmütiger Anwendung der Regel zu einem schlechten Ergebnis kommt, eben weil die Regel inhärent schlecht ist, nicht bloß weil irgendein Klugscheißer den Wortlaut der Regel falsch auslegen kann.

Ich finde deine Funktionsnamen nicht gerade gelungen, um Kommentare als lächerlich darzustellen.

Dass 'write' irgendwie in ein file schreibt und 'print' nach cout, hab ich mir noch gedacht. Was die schreiben..keine Ahnung.
Was 'alter' in einer Klasse 'setup_t' machen soll...äh...

I guess it provides a way to alter the setup ...

@swordfish sagte in Suche Programmierer.:

Ja, aber offensichtlich unterschiedliche Daten. Oder warum sollte es sonst 2 verschiedene Funktionen geben?

Und zu write, wenn ich nur das

void write() const; // defines a const qualified function named write

zur Verfügung habe, soll ich dann anschliessend mein Dateisystem durchsuchen, wo das hingespeichert wurde? Kommentar wäre nicht schlecht.

Du glücklicher
Ist leider gerade im Python-Umfeld eine weit verbreitete Unsitte. Wahrscheinlich weil da jeder Hansel schnell eine recht "brauchbare" Bibliothek rausrotzen kann. "Brauchbar" in Anführungszeichen, weil die dann zwar theoretisch coole Sachen können, aber praktisch kann's halt niemand außer dem Autor selber nutzen.
Merke: Das wichtigste, wenn man will, dass andere Leute deinen Code nutzen, ist, dass du ihnen erklärst, wie es geht.

[ans_sked]

@seppj Nicht nur im Python-Umfeld. Auch schon in der Berufspraxis erlebt, wenn auch nicht in schriftlicher Form, sondern auf Nachfrage zu unverständlichen Code: Lies den Sourcecode (Das habe ich von einem Entwickler gesagt bekommen der 5-fach-Zeiger in C++ nutzte, meinte das alle seine Konstrukte schneller als vergleichbare stl-Funktionalitäten wären...).

Bei uns checked Jenkins regelmäßig, ob es fehlende/falsche Kommentare bei Funktionen gibt.
Das ist zwar auch nervig "setA" mit "sets A" zu kommentieren, aber besser als das, was ihr scheinbar durch machen müsst.

Würde ich nicht sagen... Wir habens paar mal mit Doxygen Kommentaren probiert, aber das hilft kaum was. Der Code und die Prozesse sind einfach zu komplex, ist alles mit der Zeit gewachsen und kaum durch Kommentare zu erklären. Man muss sich einfach auskennen. Und dafür muss man erstmal die Begriffe und Zusammenhänge kennen. Das müsste man schon richtig dokumentieren und beschreiben, was tatsächlich passiert, unabhängig von irgendwelche konkreten Klassen und Funktionen.
Ich will jetzt nicht sagen, dass die Situation optimal ist, aber das ist uns schon bewußt und wir reden durchaus ab und zu drüber, aber wir haben jetzt noch nichts gefunden, was das ganze tatsächlich verbessern würde.

Und die ganzen Firmen, in denen ich früher gearbeitet habe, waren zu klein, da hätt sich das nicht gelohnt, und soo komplex war das alles auch nicht.

@mechanics sagte in Suche Programmierer.:

Da haben wir es gut. Unsere weise Führungsriege weiß, dass man Jahrzehnte gewachsenes Knowledge von heute auf morgen durch einen Inder ersetzen kann...mmh ich höre besser auf...

So ähnliche Ideen gabs bei uns auch
