Wow, this is great! This should definitely be added to guile by default. Aleix ^ permalink raw reply [flat|nested] 8+ messages in thread

About these "possible unbounded variable" warnings, I have for GNU TeXmacs the opposite need: how can I turn them off? :) I was also curious to ask: which are currently the major applications of GNU Guile (as extension language)? For example, in TeXmacs we have ~110.000 lines of scheme (still Guile 1.8). I wanted to give a look around to understand what are good design patterns to use Guile 2+ as extension language.

However I would prefer not to make large changes in this moment. I removed most of the warnings by proper use of modules but we still have some circular dependencies among modules and these are sources of some warning which for the moment I just want to silence. I think as long as they are warnings there should be the option to suppress them. There is no error in the code, but the current way circular module dependence in guile is handled does not recognize it... Best, Max > On 19.

In Guix, the hint is displayed by an 'unbound-variable exception handler, not by the 'unbound-variable printer; I think doing it in the printer could be confusing. Perhaps what could be done is export an 'unbound-variable handler that does all this, and have the REPL use it? Thanks, Ludo’. ^ permalink raw reply [flat|nested] 8+ messages in thread

The dilemma is whether to search available modules in the current repository, or in the whole of core guile. Do we want to show e.g. "Unbound variable: vector-for-each.
