|Priority||normal||Severity||minor||Reproducibility||have not tried|
|Target Version||4.02.1+dev||Fixed in Version|
|Summary||0006429: A format specifier for bytes|
|Description||Without a %S-like format specifier for Bytes, debugging becomes extremely annoying--the code is littered with bogus conversions everywhere. Perhaps it's possible to provide one?|
It also makes sense to provide its non-escaped equivalent as well ("%s").
|Tags||No tags attached.|
|I have no idea of what a good syntax would be. My only idea would be to reuse "%#s" (currently considered as "%s", but planning-to-be-outlawed in 4.02 as it doesn't mean anything), and it's mediocre at best.|
|Well, you could disambiguate the conflict with %b/%B by using the second letter: %y/%Y, in the same way as e.g. options for Unix tools are disambiguated. This is what I would expect, at least.|
Note that in the meantime, we could make sure that
"%a" Bytes.print by
"%a" Bytes.to_string by
works (by adding the relevant functions if need be for some *printf function), which would already have reasonable readability.
While we decide which letter to use, you should use this for debugging without too much pain:
let (!!) = Bytes.unsafe_to_string;;
Printf.printf "hello %s\n" !!my_byte_sequence;;
For the letter, I think Y is a good candidate. My first idea was Z but we might want to use that for bignums at some point in the future.
As for %#s, that would make the type depend on the format's flags rather than the letter. A very bad idea.
