2020-06-09Update `OP_HASH` generation to support big hash creation.Yukihiro "Matz" Matsumoto
2020-06-05Change arena index from `mrb_int` to `int`.Yukihiro "Matz" Matsumoto
2020-06-02Remove `patch_irep()` in `mruby-eval`dearblue
- It can now deal with operands in the range of `OP_EXT*`. - It can now call the same method as the variable name without arguments. ```ruby def a "Safe!" end a = "Auto!" eval "a()" # call method `a` ```
2020-05-25Add `y.tab.c` to remove Bison from build dependencies; ref 4ce3997cKOBAYASHI Shuji
I sometimes see Bison related problems in setting up build environments. Therefore to remove Bison from build time dependencies, add `y.tab.c` generated by Bison to the repository. The reduction of dependency at build time also reduces the labor and time for setup and installation in CI. In addition, a path in `#line` directive is converted to a relative path so that its path is constant regardless of development environments.
2020-05-15Remove `YYERROR_VERBOSE` which no longer supported since `bison 3.6`.Yukihiro "Matz" Matsumoto
Instead we added `%define parse.error verbose`.
2020-05-09Fix boundary check for `OP_LOADI16`; ref fa8668cdearblue
It was making a negative integer if the highest-order bit of a 16-bit integer was 1. no patched: ```ruby p 0x7fff # => 32767 p 0x8000 # => -32768 p 0xffff # => -1 p 0x10000 # => 65536 ```
2020-05-07Add a new instruction `OP_LOADI16`.Yukihiro "Matz" Matsumoto
Which loads 16bit integer to the register. The instruction number should be reorder on massive instruction refactoring. The instruction is added for `mruby/c` which had performance issue with `OP_EXT`. With this instruction, `mruby/c` VM can just raise errors on `OP_EXT` extension instructions.
2020-05-07Fix wrong line number before comment line; fix #4993Yukihiro "Matz" Matsumoto
2020-04-27Updating `parse.y for recent `bison` (retry).Yukihiro "Matz" Matsumoto
2020-04-27Revert "Change obsolete `%pure-parser` to `%define api.pure`."Yukihiro "Matz" Matsumoto
This reverts commit 682a31f92b3ac86ca59f7e8e740197e50b4452e5. Unfortunately, I couldn't run newer `bison` on TravisCI. Maybe next time.
2020-04-27Change obsolete `%pure-parser` to `%define api.pure`.Yukihiro "Matz" Matsumoto
Recent `bison` warns for `%pure-parser`. We kept it since MacOS only provide ancient `bison`, but the warning is noisy and there's no hope that Apple will upgrade `bison`. MacOS users must install the newer version of `bison`, by typing `brew install bison` for example. Note that `brew` does not overwrite the `bison` execution path automatically, so you need to update your `.bash_profile` as instructed by `brew`.
2020-04-25Implemented argument forwarding by `...`Yukihiro "Matz" Matsumoto
2020-04-01Avoid unnecessary `nextc()` recursion.Yukihiro "Matz" Matsumoto
2020-01-08`p->locals` may be `NULL` when error occurs before the point.Yukihiro "Matz" Matsumoto
This is reported by oss-fuzz: Issue 19886: mruby:mruby_fuzzer: Potential-null-reference in setup_numparams
2020-01-06Avoid creating temporary objects in `read_irep_record_1`; close #4920Yukihiro "Matz" Matsumoto
The basic idea of this change is from @dearblue. Note: the arguments of `mrb_str_pool()` have changed, but the function is provided for internal use (No `MRB_API`). So basically you don't have to worry about the change.
2020-01-05Fix ainfo with keyword arguments; fix #4921dearblue
2020-01-01Allow `here-doc` in the middle of Hash expressions; fix #4815Yukihiro "Matz" Matsumoto
2019-12-27Prohibit assignment to numbered parameters.Yukihiro "Matz" Matsumoto
It is stricter than CRuby but confusing anyway.
2019-12-27Allow non numbered-parameter identifier like `_1` outside of blocks.Yukihiro "Matz" Matsumoto
But it causes warnings as CRuby does; fix #4892 fix #489
2019-12-27Numbered parameters: usually linked list uses `cdr` for links.Yukihiro "Matz" Matsumoto
2019-12-27Prohibit numbered parameters as method arguments; fix #4892Yukihiro "Matz" Matsumoto
As of CRuby2.7 it is only warned. `mruby` prohibits explicitly to implement the future Ruby3 behavior.
2019-12-23Handle CR LF newline natively in lexertake-cheeze
2019-12-21Numbered parameters should not be available in the lambda bodies.Yukihiro "Matz" Matsumoto
`mruby` does not warn like `CRuby` for cases like #4893. Fix #4890, fix #4891, fix #4893.
2019-12-21`_0` is not numbered parameterKOBAYASHI Shuji
#### Before this patch: ```console $ bin/mruby rb -e '_0=:l; p ->{_0}.()' -e:1:13: _0 is not available -e:1:13: syntax error, unexpected $end, expecting '}' ``` #### After this patch (same as Ruby): ```console $ bin/mruby rb -e '_0=:l; p ->{_0}.()' :l ```
2019-12-21Fix SEGV from numbered parameters outside of blocks; fix #4862Yukihiro "Matz" Matsumoto
2019-12-09Warnings for numbered parameters in nested blocks.Yukihiro "Matz" Matsumoto
2019-12-09Parser refactoring on numbered parameters.Yukihiro "Matz" Matsumoto
Now identifiers like `_1abc` are allowed.
2019-12-09Support new numbered parameter syntax `_1` instead of `@1`.Yukihiro "Matz" Matsumoto
2019-12-09Implement numbered parametersUkrainskiy Sergey
2019-11-19Always enable the rational and complex literalsKOBAYASHI Shuji
I think they can always be enabled because the regular expression literal is always enabled.
2019-11-14Fix here document with EOFKOBAYASHI Shuji
#### Before this patch: ``` $ bin/mruby -e 'p <<EOS 1 EOS' -e:4:0: can't find heredoc delimiter "EOS" anywhere before EOF -e:4:0: syntax error, unexpected $end, expecting tHEREDOC_END or tHD_STRING_PART or tHD_STRING_MID ``` #### After this patch (same as Ruby): ``` $ bin/mruby -e 'p <<EOS 1 EOS' "1\n" ```
2019-11-13Use `mrb_intern_lit` if possible in `parse.y`KOBAYASHI Shuji
2019-11-12Use `intern` instead of `intern_cstr` if possible in `parse.y`KOBAYASHI Shuji
2019-11-08Fixed a bug in keyword arguments in block parameters; fix #4810Yukihiro "Matz" Matsumoto
This is caused by incomplete fix in #4746
2019-11-08Allow here-doc before closing parentheses; ref #4796Yukihiro "Matz" Matsumoto
2019-11-04Avoid using C++ style comments (`//`) in `parse.y` [ci skip]KOBAYASHI Shuji
2019-10-30Fix here-doc inside parens and brackets; fix #4796Yukihiro "Matz" Matsumoto
2019-10-11Move exception raising to `scope_new`.Yukihiro "Matz" Matsumoto
Besides that fix bugs that mistakenly calls `raise_error` that emits code to raise runtime error instead of `codegen_error` that terminates code generation immediately.
2019-10-04Refactor local variables addition in optional/keyword arguments.Yukihiro "Matz" Matsumoto
2019-10-03Add local variable reordering to `kwargs`; ref #4746Yukihiro "Matz" Matsumoto
2019-10-03Need to reorder local variables defined in `opt`; fix #4746Yukihiro "Matz" Matsumoto
For example, local variables in the following def: ```ruby def foo(a = (not_set = true), &block) ... end ``` should be `a, block, not_set`, but were `a, not_set, block`.
