Hi, lloda <[email protected]> skribis: > I think excessive output is a more serious problem, because it should be possible to go to a backtrace frame and look at objects directly. On the other hand, it should also be possible to C-c when guile starts to flood the terminal. But neither of these workarounds is reliable :-/ Ultimately this printing should be configurable. > > We already have the repl-option system (repl-option-set! repl 'print ...). This system doesn't apply to exception messages nor backtraces. I think if it did, that would mostly solve the problem. Yes. Right now it’s just $COLUMNS; we should have a documented SRFI-39 parameter for that. > I also think that, besides options to truncate or not, we should have a pager (display at most a page, give options to next/stop/all). That would be the best default. Yes! Ludo’.
