Yukihiro "Matz" Matsumoto ff08856fe3 Remove implicit conversion using to_str method; fix #3854 
We have added internal convenience method `__to_str` which
does string type check.

The issue #3854 was fixed but fundamental flaw of lack of stack
depth check along with fibers still remains. Use `MRB_GC_FIXED_ARENA`
for workaround.

Yukihiro "Matz" Matsumoto 346f154ece Implement String#delete and #delete!; ref #4086 
mruby restriction:

Yukihiro "Matz" Matsumoto 58f7f2361a Implement String#count; ref #4086

Yukihiro "Matz" Matsumoto 68523b4ec4 Add String#squeeze and #squeeze!; ref #4086 
mruby restriction:
`String#squeeze` can take more than 1 pattern arguments in CRuby,
in that case, the intersection of patterns will be used to match.
But in mruby, it doesn't take multiple patterns.

Yukihiro "Matz" Matsumoto c0ae8a96a1 Add String#tr_s and String#tr_s!; ref #4086 2018-09-21 00:03:07 +09:00
Yukihiro "Matz" Matsumoto 58ba38fe1e Add String#tr and #tr! to mruby-string-ext gem; fix #4086 
This patch is based on `mruby/c` implementation by Hirohito Higashi.

We might need to add `#tr_s`, `#squeeze` and `#delete` as well.
Adding them should not be too hard using functions we implemented here.

Yukihiro "Matz" Matsumoto 5e1d923381 Changed the behavior of mrb_range_beg_len(); close #3411 
The new API is:

int mrb_range_beg_len(mrb, range, &beg, &len, len, trunc)

The new argument `trunc` is a boolean value that specifies
whether the function truncates the range. The new return value
is an integer instead of a boolean, that is:

 0: not a range
 1: range with proper edges
 2: out of range

To get the old behavior, you have to rewrite:

  mrb_range_beg_len(mrb, range, &beg, &len, len)

to:

  mrn_range_beg_len(mrb, range, &beg, &len, len, TRUE) == 1
