Macro in TexStudio

Für solche Ersetzungen kann man Reguläre Ausdrücke (engl: regular expressions) verwenden. Diese aktiviert man, indem man im Ersetzen-Dialog, den Schalter mit »Reg« betätigt.

Nun wollen wir 12mm durch \SI{12}{\mili\metre} ersetzen, wobei die 12 natürlich variabel sein darf. Dafür verwenden wir im Suchen-Feld

1
([0-9]+)mm

Das bedeutet, finde alle Muster mit einer oder mehr Ziffern [0-9]+, gefolgt von mm und speichere die Ziffern in der ersten Gruppe ().

Im Ersetzen-Feld verwenden wir dann

1
\\SI{\1}{\\milli\\metre}

wobei wir den umgekehrten Schrägstrich durch doppeln »schützen« müssen. Den Inhalt der ersten Gruppe bekommen wir mit \1.

Nach einem Druck auf »Ersetzen« erhalten wir das gewünschte Ergebnis.

Für die anderen beiden brauchen wir die folgenden Ausdrücke:

1
2
3

123cm2 in \SI{123}{\centi\metre\squared}  ([0-9]+)cm[0-9]  \\SI{\1}{\\centi\\metre\\squared}
123cm in \SI{123}{\centi\metre}           ([0-9]+)cm       \\SI{\1}{\\centi\\metre}

Dabei ist wichtig, dass man zuerst 123cm2 ersetz und dann 123cm, da ja 123cm ein Teil von 123cm2 ist.
