When gsd-from-source is invoked via a symlink (e.g. ~/.bun/bin/gsd-real pointing at it so `gsd` resolves to source without further indirection), BASH_SOURCE[0] is the symlink path, not the real file. The previous dirname-of-BASH_SOURCE[0] approach resolved SCRIPT_DIR to the symlink's parent dir (e.g. ~/.bun/bin) and tried to bun-run ~/.bun/src/loader.ts, which doesn't exist. Wrapping BASH_SOURCE[0] in readlink -f resolves the physical path first, so SCRIPT_DIR always points at bin/ inside the gsd source checkout regardless of how the script is reached.

# gsd-from-source — run GSD directly from this source checkout via bun.
|
|
#
|
|
# Purpose: every local commit in this repo (e.g. the #4251 fix) is live
|
|
# immediately without reinstalling the bun-packaged gsd-pi. Subagents can
|
|
# spawn gsd by pointing GSD_BIN_PATH at this script instead of dist/loader.js.
|
|
#
|
|
# Contract:
|
|
# - Executable shim spawn() / exec() can launch directly.
|
|
# - Exports GSD_BIN_PATH before handing off to loader.ts so loader.ts's
|
|
# `GSD_BIN_PATH ||= process.argv[1]` branch preserves the shim path
|
|
# instead of clobbering it with the .ts loader path (which is not
|
|
# directly executable by child_process.spawn).
|
|
#
|
|
# Requirements: bun on PATH, node_modules populated (`bun install` once).
