Mein Emacs

Submitted by Erik Wegner on

Die folgenden Punkte sind für Emacs konfiguriert:

Paket-Quelle

Als Quelle der hier verwendeten Pakete dient das MELPA-Repository. Die Einrichtung ist unter Getting Started beschrieben.

Für Systeme ohne Internetverbindung gibt es elpa-mirror, dass die Pakete zur späteren Installation zusammenstellt.

Einrückungen

Der Blog-Eintrag zeigt eine elegante Möglichkeit, verschiedene Einrück-Konfigurationen anzulegen und dazwischen zu wechseln.

Datei- und Projektverwaltung

Dies erledigt die Kombination aus Projectile und Neotree.

Motiv

Als Einfärbe-Thema habe ich Cyberpunk gewählt.

1. Install an Emacs version that does support SSL and be safe.
