grammarblobprobe

Overview ¶

Command grammarblobprobe is a minimal binary that blank-imports the grammars package so that whatever grammar blobs are embedded by the active build tags are linked into the binary. It exists to measure the embedded-blob payload of each grammar-selection build mode (default, grammar_set_core, grammar_subset, grammar_blobs_external) — the binary's size is the measurement.

go build -o /tmp/probe.full                                   ./cmd/grammarblobprobe   # all blobs
go build -tags 'grammar_subset grammar_subset_go' -o /tmp/probe.go ./cmd/grammarblobprobe   # go only

A grammar_subset build that embeds only the selected blobs will be dramatically smaller than the default all-grammars build.
