# default.mk — project variables, tool detection, and output formatting.
#
# Included by the root Makefile.  Every variable is defined with ?= so any of
# them can be overridden on the command line or in the environment:
#
#   make build VERSION=v1.2.3
#   make lint  LINT=/usr/local/bin/golangci-lint
#
# Requires GNU make >= 3.81 (the version shipped with macOS Xcode CLT).

# The directory that contains this file, which is also the repository root.

# ── Versioning ────────────────────────────────────────────────────────────────
#
# Derived from the nearest reachable git tag.  Falls back to "dev" in shallow
# clones, detached HEADs without tags, or non-git directories.

# ── Build flags ───────────────────────────────────────────────────────────────
#
# -trimpath   strips local file-system paths for reproducible builds.
# -s -w       strip the symbol table and DWARF info to shrink the binary.
# -X          embeds the version string at link time.

# ── Color / formatting ────────────────────────────────────────────────────────
#
# Honors three opt-out signals:
#   NO_COLOR  — set to any value to disable (https://no-color.org/)
#   CI        — set to any value (most CI/CD platforms set this automatically)
#   TERM=dumb — indicates a terminal with no escape-sequence support
#
# When all conditions are satisfied, colors are enabled by embedding the real
# ESC byte (0x1B) once via printf rather than using \033 literals throughout —
# this keeps every downstream variable self-contained and portable across both
# GNU awk and BSD awk (macOS).
#
# _COLORS_OK is the single gate: downstream code checks only this variable.
