The REPL already reads a piped script over one connection, but there was no way
to wait *inside* it. Anything that needed a pause - let the game run a few
seconds, wait for a breakpoint that isn't the direct answer to the previous
line - had to be split across several wsdbg invocations, each paying for a
process, a TCP connection and a handshake. A polling loop built that way took
minutes per run and was the main reason driving headless felt slow.
Adds four directives that run inside the session:
:sleep <seconds> pause, still draining and printing messages
:wait <event> [timeout] block until that event arrives (e.g. cpu.stepping)
:echo <text> mark up the output
# comment ignored
and --compact, which prints one line per message (`<- event {json}`) instead of
pretty-printed JSON and drops the banner and prompt, so a shell can grep the
output instead of reassembling it. wsdbg now also exits non-zero if a :wait
timed out, so a script can be checked without parsing output at all.
:sleep deliberately keeps reading the socket rather than blocking on a timer -
otherwise broadcasts stop printing and the connection backs up behind them.
Together with cpu.runUntilTime this collapses a repro that needed a shell
driver, a polling loop and a JSON-reassembling filter into one file:
{"event":"broadcast.config.set","disallowed":{"logger":true,"input":true}}
cpu.runUntilTime us=1500000
:wait cpu.stepping 60
cpu.status
cpu.stepInto
