Daniel Jasper 69694b0691 clang-format: [JS] Fix regex literal detection. 
Before:
  var regex = /= / ;

After:
  var regex = /=/;

Daniel Jasper 9326f91922 clang-format: [JS] support optional methods. 
Optional methods use ? tokens like this:

  interface X { y?(): z; }

It seems easiest to detect and disambiguate these from ternary
expressions by checking if the code is in a declaration context. Turns
out that that didn't quite work properly for interfaces in Java and JS,
and for JS file root contexts.

Patch by Martin Probst, thank you.

Daniel Jasper f69b922e57 clang-format: [JS] Fix calculation of template string width. 
OriginalColumn might not be set, so fall back to Location and SourceMgr
in case it is missing. Also initialize end column in case the token is
multi line, but it's the ` token itself that starts the multi line.

Daniel Jasper d22190632c clang-format: [JS] Fix templated parameter default values. 
Parameters can have templated types and default values (= ...), which is
another location in which a template closer should be followed by
whitespace.

 2015-03-15 13:59:51 +00:00
Daniel Jasper 60948b12bb clang-format: [JS] more precisely detect enums. 
The current enum detection is overly aggressive. As NestingLevel only
applies per line (?) it classifies many if not most object literals as
enum declarations and adds superfluous line breaks into them. This
change narrows the heuristic by requiring an assignment just before the
open brace and requiring the line to start with an identifier.

Patch by Martin Probst. Thank you.

Daniel Jasper 8370908667 clang-format: [JS] Support classes.

Daniel Jasper a4e55f4d1e clang-format: [JS] Don't put top-level dict literals on a single line.

Daniel Jasper 49a9a2833b clang-format: [JS] Support more regex literals. 
Previously a regex-literal containing "/*" would through clang-format
off, e.g.:
  var regex = /\/*$/;

Would lead to none of the following code to be formatted.

Daniel Jasper 1779d438bc clang-format: [JS] Improve formatting of function literals in chains

 2014-09-19 10:48:15 +00:00
Daniel Jasper 23376259c0 clang-format: [JS] Support regex literals with trailing escaped slash. 
Before:
  var regex = / a\//; int i;

After:
  var regex = /a\//;
  int i;

This required pushing the Lexer into its wrapper class and generating a
new one in this specific case. Otherwise, the sequence get lexed as a
//-comment. This is hacky, but I don't know a better way (short of
supporting regex literals in the Lexer).

Pushing the Lexer down seems to make all the call sites simpler.

Daniel Jasper 3a038de3c8 clang-format: [JS] JavaScript does not have the */&/&& madness. 
Before:

Yeah, this might be useful for C++, too, but it is not such a frequent
