#!/bin/bash
# tests/term_config.sh -- assert the terminal CONFIG loader and decoder.
#
# The shell reads TP3.TRM at startup (TermCfg.Load) instead of having escape
# sequences patched into it.  This suite is that loader's oracle: it feeds a
# fixture config to a tiny harness and compares every decoded sequence byte for
# byte.  The interesting cases are the ones an eyeball misses:
#
#   * \e must be ONE ESC byte, not a backslash and an 'e';
#   * ^G must be BEL (07), not '^' and 'G';
#   * the ANSI default must survive when no keys are given;
#   * VT52's GOTO uses %R/%C (raw bytes), which are still just text here - the
#     shell substitutes them, and their presence is pinned so the substitution
#     site cannot silently lose them.
#
# It is a separate suite, not part of the shell UI tests, because the loader is
# pure data: no pty, no screen, no timing.
