Hello all,
I get a strange behaviour while trying to print hexadecimal values of a string.
Context: I get a SHA1 hash from a binary stream, store it into a string, and I want to display that string (using asHex).
Problem: for values inferior to 16, the leading zero is ignored. (15 -> 'F' instead of '0F').
indeed printStringHex prints F instead of 0F 15 printStringHex 'F' 15 hex '16rF'
Geoffroy could you add a variant that produces the correct behavior with some tests?
No need to do that. As Sven pointed out, he can simply use ByteArray >> #hex. Since his stream is already binary, he can also avoid converting his data to a string. Levente
I could modify SmallInteger>>printStringBase: to always include the leading zero, but I fear I'm going to break a lot of code doing that. Is there a better way to fix my problem? apart from using directly the following: aStream do:[:val | val printStringBase:16 nDigits:2]
Best regards,
Geoffroy
