01077c1299 fix(45417): show inlay hints for null and literal-like identifiers 2021-08-12 09:52:41 +03:00
Eli Barzilay
635f5bdf8c Some tweaks for backtick strings
1. `getRawLiteral()`: barf if `currentSourceFile` is missing, since if
   it is, then the following `getSourceTextOfNodeFromSourceFile` will
   return a bogus `""`.

2. One `||` -> `??` change.

3. `backtickQuoteEscapedCharsRegExp`: escape the usual control
   characters except for a simple LF.  This code does get used to
   generate backtick strings when `rawText` is not given, and not
   escaping things like TAB characters can get mangled by editor
   settings.  Worse, not escaping a CRLF and putting it verbatim in sthe
   string source will interpret it as LF, so add a special case for
   escaping these as `\r\n`.
   Added test.

Related to #44313 and #40625.

086423729a Add jsdoc member names: Class#method (#44150)
* Everything mostly works

A couple of mixed, nested references don't work yet.
The scanner+parser interaction is wrong, the parser consumes one too
many spaces, and the checker+services code needs a little cleanup.

* Cleanup

1. I decided that correctly parsing a#b.c, an entity name containing an
instance reference, is not worth the work.
2. I made the scanner, at least the jsdoc part, emit a # token, and
provided a reScanPrivateIdentifier in order to convert #a to # a.
3. I cleaned up the code in the checker.
2. Unrelated: I added a missing space in linkPart display.

* Cleanup lint + var naming

* investigate+clean up a couple of TODOs

* Fix lint in utilities.ts

* change name to JSDocMemberName

* address PR comments

87d10eb055 Eliminate well known symbols as a concept in the checker and rely on unique symbols (#42543)
* Eliminate well-known symbols in the checker: 2021 edition

* Actually update the lib text to say unique symbol, too (this is unneeded with compat code in place, but this makes goto-def make more sense)

* Add test showing mismatched symbol constructor type interop

* Add more test cases for some other related issues this fixes

* Revert computed name change

* Style comments

f462576ac2 Re-do tracing initialization and tests around calls
Make `tracing` either `undefined` or the same namespace as before.
Switching all calls to `tracing?.___` means that there is no cost for
a call or the arguments when tracing is not used.  Comparing two runs
without tracing (27 runs, drop 5+5, avg rest) I get:

    master:
      42.59s user 1.00s system 165% cpu 26.372 total
    changed:
      42.01s user 0.982 system 165% cpu 26.039 total

(Makes it all private, so no api changes.)
