Ephemeral web containers lose installed tools on restart. Add an idempotent, non-fatal SessionStart hook that (re)installs GNAT+gprbuild+GnuCOBOL (apt), ponyc (ponyup), and Alire alr 2.1.1 when missing, and ensures ponyc is on PATH. Appended alongside the existing R/Octave session-start hook. User-authorized.

# SessionStart hook — install the polyglot build toolchains for this repo.
|
|
#
|
|
# Claude Code on the web runs in an ephemeral container: anything installed
|
|
# outside the cached project tree vanishes on restart. This hook reinstalls the
|
|
# toolchains the project depends on at the start of every session:
|
|
# * GNAT + gprbuild + GnuCOBOL (apt: gnat gprbuild gnucobol)
|
|
# * Pony (ponyc) via ponyup
|
|
# * Alire (alr) 2.1.1 (prebuilt release zip)
|
|
#
|
|
# Design rules:
|
|
# * IDEMPOTENT — each tool is skipped if it is already on PATH (command -v).
|
|
# * NON-FATAL — a failed download/install must NOT break the session. We never
|
|
# run `set -e`; every step is guarded and the script always exits 0.
|
|
# * Warnings (not errors) are logged so failures are visible in the session log.
