06:16 AM Ruby Revision ec0a6af1 (git): [ruby/syntax_suggest] Handle `on_sp` when using prism

It used to not emit this token type, but now it does.
So when a newer version of prism is present, we can fall back
to the same code that ripper uses.

08:12 PM Ruby Revision dc90c26a (git): [ruby/prism] Respect `encoding` option in `Prism.lex` and friends

utf-8 is the default for source files but can be overwritten via options

08:12 PM Ruby Revision 07ae044b (git): [ruby/prism] Take the strings encoding as the initial encoding in the ripper translator

When no magic encoding comment is present, it does not default to utf-8,
and takes the encoding of the string that contains the source code instead.
Most of the time that will be utf-8, but not always.

08:27 PM Ruby Revision 203d1271 (git): [ruby/prism] Use less `visit_token` in the ripper translator

The ripper translator is a good resource when porting ripper usage over to prism
A few places use `visit_token` when it can be more specific.
A call operator for example can ever only be one of three things.
A positional argument can on... Earlopain (Earlopain _)

03:22 PM Ruby Revision 0cbd210c (git): [ruby/prism] Optimize ripper bounds

Basically a port of https://github.com/ruby/ruby/commit/c45f781771314a71856c9b348c640ba532f54349 into ruby
It's quite effective at ~97% hit rate for me.
Speeds it up from ~6.77x slower to only 4.07x slower.
For the lexer `on_sp` it als... Earlopain (Earlopain _)

03:22 PM Ruby Revision 1367f885 (git): [ruby/prism] Freeze the parse result for the ripper translator

It's a small, somewhat hacky performance boost. Locations are lazy, by freezing the
result they don't have to be pack/unpacked redundantly.
This gives about a 4% speed boost.
Other changes are to not modify the frozen AST

03:22 PM Ruby Revision 1aa62e89 (git): [ruby/prism] Optimize ripper `visit_token`

It was showing up in profiles.
So:
* Don't splat `KEYWORDS` (also did the same for `BINARY_OPERATORS`)
* Use `start_with?` if possible
Overall gives a ~5% speed boost
