* Silence incorrect assigned but unused variable warnings in ripperJeremy Evans2019-12-041-0/+2
| | | | | | | To only emit the warnings in correct cases would require tracking local variable usage in ripper, which ripper currently does not do. Fixes [Bug #15188]
* Make single line pattern matching void expressionNobuyoshi Nakada2019-11-301-0/+11
| | | | | Instead of returning `nil`, raise a syntax error if its value is used. [Feature #16355]
* Raise `NoMatchingPatternError` when expr `in` pat doesn't matchNobuyoshi Nakada2019-11-281-1/+1
| | | | | | | | * `expr in pattern` should raise `NoMatchingError` when unmatched * `expr in pattern` should return `nil`. (this is unspecified, but this feature is experimental, at all) [Feature #16355]
* [ripper] Fixed unique key check in pattern matchingNobuyoshi Nakada2019-11-261-67/+52
| | | | | | Check keys * by an internal table, instead of unstable dispatched results * and by parsed key values, instead of escaped forms in the source
* Hoisted out `push_pvtbl`/`pop_pvtbl`Nobuyoshi Nakada2019-11-261-16/+19
|
* Wrap `p_kw` in an array at `p_kwarg`Nobuyoshi Nakada2019-11-261-3/+4
| | | | | Not in `p_kw` itself, which makes key and variable/expr pair only now.
* [ripper] Quoted label without expression must be a local variableNobuyoshi Nakada2019-11-251-34/+58
| | | | | | | | | The difference from 0b8c73aa65add5c57b46b0cfdf4e661508802172 is to add the result of `string_add` event to marking objects. ```C RNODE($1)->nd_rval = add_mark_object(p, $$); ```
* Revert "[ripper] Quoted label without expression must be a local variable"Nobuyoshi Nakada2019-11-201-58/+34
| | | | | This reverts commit 0b8c73aa65add5c57b46b0cfdf4e661508802172, which seems breaking RVALUE consistency check.

* Warn on access/modify of $SAFE, and remove effects of modifying $SAFEJeremy Evans2019-11-181-1/+1
| | | | | | | | | | | | | | | | | This removes the security features added by $SAFE = 1, and warns for access or modification of $SAFE from Ruby-level, as well as warning when calling all public C functions related to $SAFE. This modifies some internal functions that took a safe level argument to no longer take the argument. rb_require_safe now warns, rb_require_string has been added as a version that takes a VALUE and does not warn. One public C function that still takes a safe level argument and that this doesn't warn for is rb_eval_cmd. We may want to consider adding an alternative method that does not take a safe level argument, and warn for rb_eval_cmd.
* delete unused functions卜部昌平2019-11-141-35/+2
| | | | | | | | | | | | Looking at the list of symbols inside of libruby-static.a, I found hundreds of functions that are defined, but used from nowhere. There can be reasons for each of them (e.g. some functions are specific to some platform, some are useful when debugging, etc). However it seems the functions deleted here exist for no reason. This changeset reduces the size of ruby binary from 26,671,456 bytes to 26,592,864 bytes on my machine.

| | | | It is unnatural and probably a typo.
* Revert "Warn `if` and `elsif` at EOL [EXPERIMENTAL]"Yusuke Endoh2019-11-041-22/+0
| | | | | This reverts commit ba35c14325ebbf1da8f200df83c45ee9937ff8a1. This is because ripper fails symbol lookup error.
* Warn `if` and `elsif` at EOL [EXPERIMENTAL]Nobuyoshi Nakada2019-11-041-0/+22
| | | | It is unnatural and probably a typo.

* Define arguments forwarding as `ruby2_keywords` styleNobuyoshi Nakada2019-10-251-1/+19
| | | | | | | | | | | | Get rid of these redundant and useless warnings. ``` $ ruby -e 'def bar(a) a; end; def foo(...) bar(...) end; foo({})' -e:1: warning: The last argument is used as the keyword parameter -e:1: warning: for `foo' defined here -e:1: warning: The keyword argument is passed as the last hash parameter -e:1: warning: for `bar' defined here ```

| | | | | | * parse.y (struct local_vars): moved numbered parameter NODEs for nesting check to separate per local variable scopes, as numbered parameters should belong to local variable scopes. [Bug #16248]
