Gophermap Language Support

Syntax highlighting and sane editor defaults for gophermap files — the directory format of the Gopher protocol (RFC 1436).

Features

Syntax Highlighting

All standard Gopher item types are highlighted individually:

RFC 1436 types

Non-RFC, widely supported

Gopher+ extensions

Special lines

Each field of a line (item type, display string, selector, host, port) gets its own color scope, making the tab-separated structure immediately visible.

Real Tabs — Always

Gophermap lines are tab-separated. This extension sets editor.insertSpaces: false for all gophermap files automatically, so pressing Tab always inserts a real \t — no accidental spaces that would silently break your menu.

Whitespace rendering is also enabled by default so you can see exactly where your tabs are.

File Format

A gophermap line looks like this:

[type][display string]<TAB>[selector]<TAB>[host]<TAB>[port]

Example:

i Welcome to my Gopher hole!	fake	(NULL)	0
1 Documents	/docs	gopher.example.com	70
0 About	/about.txt	gopher.example.com	70
7 Search	/search	gopher.example.com	70
h My Website	URL:https://example.com	gopher.example.com	70
.
