Test:

@import url("a\
b");

LibSass master (0dd6543) errors:

URI is missing ')'

LibSass 3.1 outputs:

@import url("a\
b");

RubySass v3.4.12 outputs:

@import url("ab");

Related test:

// without quotes
@import url(a\
b);

RubySass throws the following error:

Invalid CSS after "@import url(a": expected ")", was ""

LibSass master (0dd6543) errors:

URI is missing ')'

LibSass 3.1 outputs:

@import url(a\

Specs added sass/sass-spec#345

Fixes sass#1096

am11 · 2015-05-12T19:40:57Z

@mgreter, there is still one crazy case which is inconsistent (perhaps not worth fixing?).

(added periods to highlight spaces)

@import url("a.. .\.. .
 . . b");

Ruby Sass:

@import url("a.. ... .\a  . . b");

Current libsass master (28ee088):

@import url("a.. ... .
\a  . . b");

Not sure about logic behind ruby-sass implementation. I was expecting something like this:

@import url("a.. ... .\  . . b");

xzyfer · 2015-05-13T13:31:31Z

This still fails the spec.

xzyfer · 2015-05-13T13:40:56Z

Apologies, it looks like my local sass-spec is having issues.

xzyfer · 2015-05-13T15:11:04Z

This fix was a false positive due to sass/sass-spec#380. The spec still fails.

This is a continuation of the previous work done to bring our `url()` parsing up to scratch with Ruby Sass. With this update we can remove the trasnitional legacy `url()` parsing logic. Fixes sass#1096

@xzyfer,

quickly tested current master with the following input:

/* url-test1: without quotes */
@import url(a
b);

/* url-test1: with quotes */
@import url("a
b");

/* url-test2: with quotes */
@import url("a   \d \\d \\\d \\\\d
    c \t \n \\t \\n \\\t \\\n \\\\t \\\\n");

/* url-test2: without quotes */
@import url(a   \d \\d \\\d \\\\d
    c \t \n \\t \\n \\\t \\\n \\\\t \\\\n);

LibSass:

/* url-test1: without quotes */
@import url(a b);
/* url-test1: with quotes */
\a b"); url("a
/* url-test2: with quotes */
\a     c t n \\t \\n \\t \\n \\\\t \\\\n");
/* url-test2: without quotes */
@import url(a \d \\d \\\d \\\\d c \t \n \\t \\n \\\t \\\n \\\\t \\\\n);

RubySass:

/* url-test1: without quotes */
@import url(a b);
/* url-test1: with quotes */
@import url("a\a b");
/* url-test2: with quotes */
@import url("a   
\\d \\
\\\\d\a     c t n \\t \\n \\t \\n \\\\t \\\\n");
/* url-test2: without quotes */
@import url(a \d \\d \\\d \\\\d c \t \n \\t \\n \\\t \\\n \\\\t \\\\n);

IMO, url-test1: with quotes is more important than rest of them.

xzyfer · 2015-12-29T03:03:48Z

Interesting. I just tested with 0f929a5 and got identical output (minus deprecation warnings)

/* url-test1: without quotes */
@import url(a b);
/* url-test1: with quotes */
@import url("a\a b");
/* url-test2: with quotes */
\\\\d\a     c t n \\t \\n \\t \\n \\\\t \\\\n");
/* url-test2: without quotes */
@import url(a \d \\d \\\d \\\\d c \t \n \\t \\n \\\t \\\n \\\\t \\\\n);

am11 · 2015-12-29T09:49:27Z

Yup, I tested on both Mac and Windows, the result is identical to yours. url-test1 in Windows is inverted from the middle. url-test2 in both are differently incorrect. I used libsass a508a7c and sassc sass/sassc@94838a9:

~/Documents/projects/libsass/sassc/bin/sassc ~/Documents/temp/blah.scss

xzyfer · 2015-12-29T15:21:12Z

@am11 sorry I'm not following your previous comment. Please be more explicitly.

Can you please post the output you're seeing on Windows, and how it differs from Mac.

Interestingly I'm unable to get the Ruby Sass output you've provided locally (on Mac), but I do see it on sassmeister.

am11 · 2015-12-29T16:04:50Z

I am running Mac and Windows 10 via Parallels. I am using sassc.

Mac (sassc running on Terminal):

~/Documents/projects/libsass/sassc/bin/sassc ~/Documents/temp/blah.scss

/* url-test1: without quotes */
@import url(a b);
/* url-test1: with quotes */
@import url("a\a b");
/* url-test2: with quotes */
\\\\d\a     c t n \\t \\n \\t \\n \\\\t \\\\n");
/* url-test2: without quotes */
@import url(a \d \\d \\\d \\\\d c \t \n \\t \\n \\\t \\\n \\\\t \\\\n);

Windows (sassc running on PowerShell):

~/Documents/projects/libsass/sassc/bin/sassc ~/Documents/temp/blah.scss

/* url-test1: without quotes */
@import url(a b);
/* url-test1: with quotes */
\a b"); url("a
/* url-test2: with quotes */
\a     c t n \\t \\n \\t \\n \\\\t \\\\n");
/* url-test2: without quotes */
@import url(a \d \\d \\\d \\\\d c \t \n \\t \\n \\\t \\\n \\\\t \\\\n);

Line below /* url-test1: with quotes */ on Windows is inverted from the middle.

Line below /* url-test2: with quotes */ on both Mac and Windows are incorrect but different from each other.

am11 · 2015-12-29T17:34:09Z

@xzyfer, sorry I was looking at the CLI output which was broken in both PowerShell and Terminal in different ways.

I just piped to a file and saw the output in editor.

scssc  blah.scss > blah.css

Mac (TextEdit)

/* url-test1: without quotes */
@import url(a b);
/* url-test1: with quotes */
@import url("a\a b");
/* url-test2: with quotes */
@import url("a   
\\d \\
\\\\d\a     c t n \\t \\n \\t \\n \\\\t \\\\n");
/* url-test2: without quotes */
@import url(a \d \\d \\\d \\\\d c \t \n \\t \\n \\\t \\\n \\\\t \\\\n);

Windows (Visual Studio and then HexEdit to check what's going on):

/* url-test1: without quotes */
@import url(a b);
/* url-test1: with quotes */
@import url("a
\a b");
/* url-test2: with quotes */
@import url("a   
\\d \\
\\\\d
\a     c t n \\t \\n \\t \\n \\\\t \\\\n");
/* url-test2: without quotes */
@import url(a \d \\d \\\d \\\\d c \t \n \\t \\n \\\t \\\n \\\\t \\\\n);

Note that in Windows output, the extra line before each \a is \r (HEX 0D). I haven't tested whether it is the raw result of compiler or is it shell redirection inserting the carriage return there. Whichever it is, this issue is fixed. Thank you! 🏆 👍

am11 · 2015-12-30T09:23:31Z

@xzyfer, I have confirmed that \r (hex: 0D) is added before both \a occurrences, by placing printf("size >>> %lu\n", strlen(output_string)); before: https://github.com/sass/sassc/blob/94838a9/sassc.c#L46.

When compiling this input sample on Mac it prints: size >>> 308 while on Windows: size >>> 310.

Any ideas where this \r it is coming from?

xzyfer · 2015-12-30T09:28:47Z

@am11 nothing comes to mind. Also I don't think this patch affected quoted
imports. Can you confirm whether this issue existed before this patch?

Also if you include debugger.cpp in context.cpp and add

debug_ast(root);

on line 657 the AST tree will be dumped to the console just before the output phase begins.

You are right, this issue was present before your fix: 2ecaa66. Note that before 15913ab, my sample was throwing SIGSEGV on both OSes, so I tested just one case: url-test1: with quotes. 😄

xzyfer · 2015-12-30T11:11:36Z

Interesting. Looks like it's worth creating an issue for. Not exactly sure how I'll debug it though haha

You can debug_ast(root) after each previous assignment of root to see if it's the parser, or eval step that introduces the \r.

Input: ```scss @import url("a b"); ``` Output on Windows: ```css "@import url(\"a\r\a b\")"; ``` Output on Unix (alinged with Ruby Sass, hence the expected output): ```css "@import url(\"a\a b\")"; ``` See: sass#1096 (comment) for details.
