clyph

clyph is a Nerd Font glyph lookup CLI for shell scripts, status lines, and agent-friendly UI work.

Search glyph names, print exact glyphs, return codepoints, and refresh a local offline catalog from Nerd Fonts CSS.

Repo: https://github.com/dabito/clyph · Issues: https://github.com/dabito/clyph/issues

Install

go install github.com/dabito/clyph@latest

Go installs the binary into $GOBIN, or $GOPATH/bin when GOBIN is unset. Default Go setups usually use:

$HOME/go/bin/clyph

Ensure Go's bin dir is on PATH:

export PATH="$HOME/go/bin:$PATH"

Initialize catalog

Lookups use a local catalog. Refresh it once after install:

clyph update

Default source:

https://www.nerdfonts.com/assets/css/webfont.css

Default catalog path:

~/.clyph/data/catalog.json

Environment override:

export CLYPH_CATALOG_PATH="$PWD/data/catalog.json" # exact catalog file override

Usage

clyph search circle --limit 5
clyph get nf-md-check
clyph glyph nf-md-check
clyph codepoint nf-md-check
clyph update --source ./webfont.css
clyph version

Use JSON for scripts:

clyph search circle --json
clyph get nf-md-check --json
clyph glyph nf-md-check --json
clyph codepoint nf-md-check --json
clyph update --json

Print a glyph inside shell output:

printf "status: %s done\n" "$(clyph glyph nf-md-check)"

Sample output

$ clyph search circle --limit 5
nf-cod-arrow_circle_down	ebfc		-
nf-cod-arrow_circle_left	ebfd		-
nf-cod-arrow_circle_right	ebfe		-
nf-cod-arrow_circle_up	ebff		-
nf-cod-circle	eabc		-

$ clyph get nf-md-check
nf-md-check	f012c	󰄬	-

$ clyph update --json
{
  "status": "updated",
  "records": 10764,
  "catalog": "/home/user/.clyph/data/catalog.json"
}

Plain output is tab-separated: name, codepoint, glyph, label. Use --json for stable machine-readable output.

Commands

clyph search <query> [--limit N] [--json]
clyph get <name> [--json]
clyph glyph <name> [--json]
clyph codepoint <name> [--json]
clyph update [--source <file-or-url>] [--json]
clyph version

Failure modes

• Missing catalog: every lookup command fails with exit code 1 until clyph update has been run once.
• Empty search: clyph search <query> with no matches prints nothing and exits 0; pass --json to get an empty matches array.
• Bad CSS source: clyph update --source <file-or-url> rejects a source that parses to zero glyph records (exit 1) and leaves the existing catalog untouched.
• Network failure: clyph update against a URL reports update failed: ... and exits 1 without modifying the catalog.
• Unknown name: clyph get|glyph|codepoint <name> prints not found: <name> to stderr and exits 1.
