2020-10-12Embed debug information to resolve Windows VC's issue.Yukihiro "Matz" Matsumoto
2020-10-12Adjust backslash position in multi-line macros.Yukihiro "Matz" Matsumoto
2020-10-12Use `MRB_INT_MAX` instead of `INT_MAX` according to variable type.Yukihiro "Matz" Matsumoto
2020-10-12Restore old function names for compatibility; ref #5070Yukihiro "Matz" Matsumoto

2020-10-12Use `mrb_int_value()` instead of `mrb_fixnum_value()`.Yukihiro "Matz" Matsumoto
Where fixnum overflow can happen.
2020-10-12Reorganize `Integer` system.Yukihiro "Matz" Matsumoto
- Integrate `Fixnum` and `Integer` - Remove `Integral` - `int / int -> int` - Replace `mrb_fixnum()` to `mrb_int()` - Replace `mrb_fixnum_value()` to `mrb_int_value()`. - Use `mrb_integer_p()` instead of `mrb_fixnum_p()`

Based on cremno/mruby@6bd0119
2020-10-12"backport" CRuby r46656; #2500Yukihiro "Matz" Matsumoto
Based on cremno/mruby@d446192
2020-10-12Rename `MRB_TT_FIXNUM` to `MRB_TT_INTEGER`.Yukihiro "Matz" Matsumoto
We still have `#define MRB_TT_FIXNUM MRB_TT_INTEGER` for compatibility.
2020-10-12change linkage to internalcremno
2020-10-12define sprintf and format as global functionscremno
2020-10-12move mrbgem initialization into sprintf.ccremno
Also remove some unnecessary code.
2020-10-12Rename float configuration option names.Yukihiro "Matz" Matsumoto
- `MRB_WITHOUT_FLOAT` => `MRB_NO_FLOAT` - `MRB_USE_FLOAT` => `MRB_USE_FLOAT32` The former is to use `USE_XXX` naming convention. The latter is to make sure `float` is 32bit float and not floating point number in general.
2020-10-12Use `mrb_funcall_id()` extensively.Yukihiro "Matz" Matsumoto
Except for support files e.g. `mruby-test/driver.c`, which are not target of symbol collection via `rake gensym`.
2020-06-20Fix potential buffer overflow in `sprintf.c`.Yukihiro "Matz" Matsumoto
2020-05-27Move `fmt_setup` until absolutely necessary.Yukihiro "Matz" Matsumoto
2020-05-26Integer format can be bigger than `32` on 64bit platforms.Yukihiro "Matz" Matsumoto
We made it `64` which should be big enough: - Format modifier: 4 characters max - Maximum width: 19 digits max - Period between width and precision: 1 character - Maximum precision: 19 digits max - Format specifier: 1 character - NUL terminator: 1 byte - Total: 45 < 64
2020-05-07Avoid `mrb_funcall` if `MRB_UFT8_STRING` is not set.Yukihiro "Matz" Matsumoto
2020-04-11Support `MRB_DISABLE_STDIO` for mruby-sprintf; ref #4954dearblue
2020-03-08Add configuration guard for `MRB_DISABLE_STDIO`dearblue
ref #4576 and ref #4947 * Need MRBAPI functions without `MRB_DISABLE_STDIO`: * mrbgems/mruby-bin-debugger * mrbgems/mruby-bin-mirb * mrbgems/mruby-bin-mrbc * mrbgems/mruby-bin-mruby * mrbgems/mruby-bin-strip * Need `stdio.h`: * mrbgems/mruby-io * mrbgems/mruby-print * Need `snprintf()` in `stdio.h`: * mrbgems/mruby-pack * mrbgems/mruby-sprintf
2020-03-08Remove unnecessary 'stdio.h'; ref #4947dearblue
'stdio.h' is included in 'mruby.h' ('mrbconf.h'). However, keep 'stdio.h' used by mruby-test.
2019-09-29Further refactoring over #4738Yukihiro "Matz" Matsumoto
2019-09-29Remove unnecessary assignmentsdearblue
2019-09-26Use proper type specifier for `mrb_raisef()`; ref #4731Yukihiro "Matz" Matsumoto
The following two may be different: * `%d` for `int` * `%i` for `mrb_int`
2019-09-26Merge pull request #4731 from dearblue/consistent-typeYukihiro "Matz" Matsumoto
Keep the type of `posarg` consistent
2019-09-25Keep the type of `posarg` consistentdearblue
Match the type with the caller and related functions.
2019-09-25Add "fall through"dearblue
2019-08-05Use new specifiers/modifiers of `mrb_vfromat()`KOBAYASHI Shuji
The binary sizes (gems are only `mruby-bin-mruby`) are reduced slightly in my environment than before the introduction of new specifiers/modifiers (5116789a) with this change. ------------+-------------------+-------------------+-------- BINARY | BEFORE (5116789a) | AFTER (This PR) | RATIO ------------+-------------------+-------------------+-------- mruby | 593416 bytes | 593208 bytes | -0.04% libmruby.a | 769048 bytes | 767264 bytes | -0.23% ------------+-------------------+-------------------+-------- BTW, I accidentally changed `tasks/toolchains/visualcpp.rake` at #4613, so I put it back.
2018-11-19Use type checking `mrb_to_str` instead of converting `mrb_str_to_str`.Yukihiro "Matz" Matsumoto
2018-11-19Removed `to_hash` conversion method.Yukihiro "Matz" Matsumoto
2018-09-14Prevent signed integer overflow.Clayton Smith
2018-09-07Fix integer overflow issue; fix #4108Yukihiro "Matz" Matsumoto
I misunderstood the return value from `snprintf()`, which is NOT number of characters written in buffer, but the number of character the buffer has to have to write the complete output.
2018-07-31Check size of the integer multiply before actual overflow; fix #4062Yukihiro "Matz" Matsumoto
2017-10-13Support MRB_WIHTOUT_FLOAT to mruby-sprintfYAMAMOTO Masaya

2017-08-18Separate `mrb_str_buf_new` and `mrb_str_new_capa`.Yukihiro "Matz" Matsumoto
`mrb_str_buf_new` is an old function that ensures capacity size of `MRB_STR_BUF_MIN_SIZE` minimum. Usually one need to use `mrb_str_new_capa` instead.
2017-08-12Reduce integer type mismatch warnings in VC.Yukihiro "Matz" Matsumoto
2017-08-09Replaced tabs with spacesChristopher Aue
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.
