jscs 3.0.3: Multiline strings with a # incorrectly flagged as "Unterminated string constant"?

[sverweij]

running jscs multistr-with-hash-NOK.js yields

Unterminated string constant (1:22) at multistr-with-hash-NOK.js :
     1 |var multilinestring = "x\n\
------------------------------^
     2 |#";
     3 |console.log(multilinestring);

1 code style error found.

Whereas running jscs multistr-without-hash-OK.js validates AOK.

Inputs

multistr-with-hash-NOK.js:

var multilinestring = "x\n\
#";
console.log(multilinestring);

multistr-without-hash-OK.js:

var multilinestring = "x\n\
y";
console.log(multilinestring);

Version information

• jscs 3.0.3 on MacOSX 10.11.4 using node 5.10.1
• I haven't been able to isolate a single rule that triggers it (tried own config, google, airbnb and an .jscsrc with {} as content

@mdevils Is this issue about CST?

[mdevils]

I think it's actually for Babel

[mdevils]

Since this is a parse error from Babel

[sverweij]

With the latest babel version it seems to work OK

$npm i -g babel-cli
(...)

$ babel --version
6.7.7 (babel-core 6.7.7)

$ babel multistr-with-hash-NOK.js
var multilinestring = "x\n\
#";
console.log(multilinestring);

$ babel multistr-without-hash-OK.js
var multilinestring = "x\n\
y";
console.log(multilinestring);

The babel (core) version installed with CST is 6.6.1 - so if babel is the culprit upgrading might be a solution?

CST doesn't use babel it uses babylon and CST uses last available version.

Not sure what to update there

Since there is nothing we can do here, i'm closing it, track the babylon issue - https://github.com/babel/babylon/issues/32
