2017-07-14Avoid duplicated width filling for sprintf `%d` specifier; fix #3736Yukihiro "Matz" Matsumoto
2017-07-05`print("%d", 0)` should not print `-0`; fix #3731Yukihiro "Matz" Matsumoto
2017-07-05Negation was not a good way to handle negative integers; fix #3729Yukihiro "Matz" Matsumoto
There's a number that negation does not work (-2147483648 in 32bit environment).
2017-07-05In Ruby, `sprintf` specifier `%u` should behave as `%d`; fix #3730Yukihiro "Matz" Matsumoto
Since there's no unsigned integer in Ruby. Binary, octal and hexadecimal negative numbers can be represented by using 2's compliment. But decimal (not being power of 2) cannot be use that kind of format.
2017-07-04Refactor `sprintf()` code.Yukihiro "Matz" Matsumoto
2017-07-04Initialize `flags` for each loop.Yukihiro "Matz" Matsumoto
2017-06-28Avoid `mrb_funcall()` unless absolutely necessary; ref #3722Yukihiro "Matz" Matsumoto
As a result, `#chr` is not called for ch < 0x80, so we need to update the "invalid chr" test.
2017-05-25Under MRB_INT64, width may be bigger than INT_MAX; fix #3665Yukihiro "Matz" Matsumoto
2017-05-08Fix segmentation fault ref: #3648ksss
2017-04-29Better error messageNobuyoshi Nakada
Raise argument error with the better message, at the only place where the size to fill can be negative.
2017-04-29Use `FILL` and `PUSH`Nobuyoshi Nakada
Instead of loop or `memcpy` after `CHECK`, use dedicated macros, `FILL` and `PUSH`, respectively.
2017-04-23Refactor "%f" % Inf/NaNNobuyoshi Nakada
As for non-finite float, calculate the exact needed size with the space flag.
2017-04-23Fix space flag when Inf/NaN and width==3Nobuyoshi Nakada
While `"% 2f"` and `"% 4f"` result in `" Inf"` and `" Inf"` respectively, `"% 3f"` results in `"Inf"` (no space).
2017-04-03Unify `else` clause styleYukihiro "Matz" Matsumoto
2017-03-18Should use mrb_int for any objectksss
o=Object.new def o.to_int 1 end p "%*d" % [o, 1]
2017-03-13Fix out-of-bound accessNobuyoshi Nakada
Get rid of out-of-bound access when single % at the end.

2015-09-03unsigned long may be smaller than mrb_int; use uint64_t instead; fix #2935Yukihiro "Matz" Matsumoto
2015-06-24Remove unnecessary backticks.Franck Verrot
Dr Markus Kuhn published in 1999 an article [1] explaining in details why we shouldn't use the ASCII grave accent (0x60) as a left quotation. Backticks have been used most notably to produce nice-looking LaTeX documents but it doesn't seem to be an issue on modern platforms and for the oldest ones, there are workarounds as mentioned by Dr Kuhn.
