# (voxgig/struct) and Lean has no port of it, so src/Plugin/Value.lean
# parses the corpus.

# elan installs to ~/.elan/bin, which a stock install does not put on a
# non-login shell's PATH, so `make test` in a fresh checkout found no
# lake. CI does not go through elan at all — it unpacks a pinned release
# to /opt/lean/bin — so only a local checkout was affected, and this is
# the same line sekreto's lean port carries. Prepending a directory that
# does not exist is a no-op, so CI is unchanged. `make` runs each recipe
# in its own shell; exporting PATH here is the only place all of them
# see it.
ELANBIN := $(HOME)/.elan/bin
export PATH := $(ELANBIN):$(PATH)
