I suggest taking this to Python ideas. While there is a legitimate concern about large objects in a Variable View, the idea impacts long-standing core APIs. Accordingly, it needs to be thought through, become better specified, and be evaluated against alternatives. If the language impact is pervasive, it would likely need a PEP as well. Some questions immediately come to mind: * Would the existing standard and third party libraries need to recode every __repr__ or __str__ implementation for every container that has ever been written? Would that include C code as well? * It there something this limit parameter could do that couldn't already be achieved with __format__()? * Should limits be a responsibility of individual classes or it is a debugger responsibility? On the one hand, it is hard to see how a debugger could implement this without blind truncation; on the other hand, I don't think other languages make a similar inversion of responsibility. * How would the parameter be accessed via the !r and !s codes in f-strings? * How easy or hard would this be to implement for typical classes, lists for example? * What is meant by "max number of symbols we want to evaluate"? Would the repr for ['x'*1_000_000] count as one symbol or as one million? * For tree-like structures (JSON for example), does a symbol limit make sense? Wouldn't you want a depth limit instead. * Would some variant of "..." be added to indicate that limits were applied and to prevent someone for accidentally running eval() on the output? ---------- nosy: +rhettinger _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41383> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
