The old version of `add_tokens` accepts an array of tokens, and
multiple arguments of tokens by using `Array#flatten`.
And `add_token` was an alias to `add_tokens`.
I think it is unnecessarily flexible; in fact, all callsites of
`add_tokens` (except test) passes only an array of tokens.
And the code created a lot of temporal arrays.
This change makes `add_tokens` accept only one array of tokens,
and does `add_token` accept one token. It is a bit faster (about
1 second in Ruby's `make rdoc`), and it ls also cleaner in my point of
view.
This change introduces a wrapper of StringScanner that is aware of the
current position (column and lineno).
It has two advantages: faster and more modular.
The old code frequently runs `@input.byteslice(0, byte_offset).length`
to get the current position, but it was painfully slow. This change
keeps track of the position at each scan, which reduces about half of
time of "Generating RI format into ..." in Ruby's `make rdoc`
(5.5 sec -> 3.0 sec).
And the old code used four instance variables (`@input`, `@line`,
`@line_pos`, and `@s`) to track the position. This change factors them
out into MyStringScanner, so now only one variable (`@s`) is needed.
When we use `define_method` and `define_singleton_method`,
if we supply block parameters to a block then a generated
method has corresponding parameters.
However, the doc doesn't mention it, so this info has been added.
My previous attempt to correct #2068 apparently failed and the confusing
wording ("instances") was merged into trunk instead.
This should address any potential confusion.
* string.c (rb_str_sub_bang): retrieves a pointer to the
replacement string buffer just before using it, for the case of
replacement with the receiver string itself. [Bug #16105]
`rb_bug()` is called at critical bug, MRI can't run anymore.
To make debug easy, this patch introduces RUBY_ON_BUG environment
variable to specify the process which is called with pid.
[Feature #16090] [GH #2331]
RUBY_ON_BUG='gdb -p' ruby xxx.rb
In this case, if ruby interpreter causes critical bug, and call
rb_bug(), then "gdb -p [PID]' is called by system(3). You can
debug on invoked gdb.
This feature is limited on RUBY_DEVEL build.
Previously, Range#=== treated string ranges that were not endless or
beginless the same as include?, instead of the same as cover?.
I think this was an oversight in 989e07c0f2,
as the commit message did not indicate this behavior was desired.
This also makes some previously dead code no longer dead. Previously,
the conditionals were doing this:
if (RB_TYPE_P(beg, T_STRING)
if (NIL_P(beg)) # can never be true
This restructures it so at the NIL_P(beg) check, beg could possibly
be nil (beginless ranges).
Fixes [Bug #15449]
Range#minmax was previous not implemented, so calling #minmax on
range was actually calling Enumerable#minmax. This is a simple
implementation of #minmax by just calling range_min and range_max.
Fixes [Bug #15867]
Fixes [Bug #15807]
Some tooling depends on the current bytecode, and adding an operand
changes the bytecode. While tooling can be updated for new bytecode,
this support doesn't warrant such a change.
This was an intentional bug added in 1.9.
The approach taken here is to add a second operand to the
getconstant instruction for whether nil should be allowed and
treated as current scope.
Fixes [Bug #11718]
Exception#backtrace and Exception#backtrace_locations can both be nil if
not set. The former can be set via `Exception#set_backtrace`, but the
later is only ever set at runtime via `setup_backtrace`.
because it's shown as just "master" on a pull request which does not
have the check_branch.master job yet.
"check_branch" would be easier to understand and now we can grep it from
master branch.
b00f280d4b introduced
an accidental behavior change in that defining a module/class under
`m` gives `m` a name when `m` is anonymous.
`ruby -ve 'Module.new { class self::A; end; p name }'` outputs a name
similar to `Module#inspect` when it should output `nil` like in Ruby
2.6.x.
* variable.c: Use `make_temporary_path` instead of `save_temporary_path`
when getting the name of the parent module.
* variable.c (rb_set_class_path): Delegate to `rb_set_class_path_string`
instead of duplicating the logic.
