fc-pattern

Parse font pattern

$ fc-pattern "[pattern]"

$ fc-pattern --default [pattern]

$ fc-pattern --config [pattern]

$ fc-pattern --format "%{family}" [pattern]

fc-pattern [options] [pattern]

fc-pattern parses and displays fontconfig patterns, showing how fontconfig interprets font matching requests. The tool is useful for debugging font configuration and understanding pattern syntax.
Fontconfig patterns specify desired font properties like family, style, weight, and size. fc-pattern reveals how these patterns are normalized and what substitutions are applied by the configuration.

-d, --default

Apply default substitutions.

Apply config substitutions.

Custom output format.

Pattern syntax can be complex. Output format requires understanding fontconfig internals. Primarily useful for debugging rather than regular font management.
