NS[C]Assert Quote Highlighting Skips Openquote

[nrichards]

Originally reported here: sublimehq/sublime_text#591. Then reported directly to GitHub who referred me to Linguist. They referred to this repository.

The quote (") syntax highlighting can carry on highlighting until the end of file, skipping / ignoring an opening quote, honoring only the closing quote, given a specific Objective-C code block.

I expect for the quote character to start highlighting at an opening quote.

Seen on GitHub, currently, in their Issue Tracker.

1 Create a new Objective-C file, e.g. "foo.m"
2 Input the following code block:

 - (void)foo {
   NSCAssert((1), @";");
   int four = 4;
 }

3 NOTICE the latter lines, beginning with int, are highlighted as if quoted.

Expecting the int line to not be quoted. Xcode renders this code correctly.

WORKAROUND: remove the semicolon (;) from the quoted string.

Doing some investigation for a bug report I found the culprit here, second affected sample:

static GstStaticPadTemplate src_template = GST_STATIC_PAD_TEMPLATE ("src",
    GST_PAD_SRC,
    GST_PAD_ALWAYS,
    GST_STATIC_CAPS ("video/x-raw, "
        "format = (string) { NV12, UYVY, YUY2 }, "
        "framerate = " GST_VIDEO_FPS_RANGE ", "

        GST_VIDEO_CAPS_MAKE_WITH_FEATURES
        (GST_CAPS_FEATURE_MEMORY_GL_MEMORY,
            "RGBA") "; "
));

The issue is in the C grammar in the #parens repository item, it does not support nesting parens. Unsure if there is a reason for this omission or if it has been left out by mistake.
