Angenommen, ich habe die folgende lange Zeile in Emacs ausgewählt. Wie kann ich zählen, wie viele Zahlen (oder NaN) ich habe?
Ich habe es versucht M-x count-words, aber es ergibt die falsche Nummer. Es heißt 1 line 1135 words and 3565 characters, aber es enthält tatsächlich 640Zahlen

Antwort1
Meine einfache Herangehensweise an dieses Problem besteht darin, count-matchesdie Datensatztrennzeichen zu zählen und dann eins hinzuzufügen. Angenommen, Ihr Trennzeichen ist ein Leerzeichen, wählen Sie die Zeile aus und geben Sie ein M-x count-matches <RET><space><RET>. Anstatt Trennzeichen zu zählen, count-matchesfunktioniert die Eingabe des folgenden regulären Ausdrucks mit Ihren Daten, ist aber mühsamer einzugeben: \b-?[0-9]+\.[0-9]+\b\|\bNaN\b. Ihre Beispieldaten zeigen keine negativen Daten, aber ich habe für den Fall, dass dies der Fall ist, das optionale „-“ in den regulären Ausdruck aufgenommen.
Antwort2
Vielleicht können Sie count-matches„mit“ \.als regulären Ausdruck verwenden.
