krds / lesslint Goto Github PK

A block of code skips the validation for the whole file.
Download it here: http://we.tl/ICo0DRgAQG

Because we need to skip rules for just a code part:

/* LessLint:ignore */
myRule{

}
/* /LessLint:ignore */

.icon {
&:extend(.sprite);
display: none;
}
Thrown Error: Colon should have no space before, and one after. at line => &:extend(.sprite);

/.dialog {
display: none;
}/
Thrown Error: Closing bracket must be on its own line

.keyframes(~'animationName, 0%{ transform: scale(1.5); color: blue; } 100%{ transform: scale(2); color: red }');

As we have to write all keys & CSS properties in one single string for this mixin, LESSlint blocking commit with following errors:

Thrown errors => Closing bracket must be on its own line
=> No need to specify units when a value is 0

As we commit these hex codes, Its throwing an error that "No units for 0 value"

lesslint rules.json /path/to/less/folder/ /path/to/file.less
    --exclude=file.less,lib.less
    --recursive

I don't understand the last 2 args. Are the 2 mandatory? Can I just indicate one (folder OR file?)

Thanks

I have a freaking issue i can't manage to solve and thus need more brain juices.

I have the following style.less file:

.f{background: url(t.png); padding: 0; border: 0; width: 0px; height: 0px;}

.skewX(){

}

Lesslint returns no error, despite there are errors :

*line 1: 
   - Closing bracket must be on its own line
   - No need to specify units when a value is 0
   - One property per line max
   - Use one space before an opening bracket: {
line 4: 
   - Use one space before an opening bracket: {
   - This line should be indented with 2 tabs
line 6, This line should be indented with 1 tab

It is because in this case _escapeNonEndOfLineSemicolon returns NULL and "clear" all content to validate so of course there is no error with an empty file.

The issue is with the pattern used:

#\((?:(?:.*)(;)(?:.*))*\)#e

Test code:

$content    =   '.f{background: url(t.png); padding: 0; border: 0; width: 0px; height: 0px;}';

var_dump(preg_match('#\((?:(?:.*)(;)(?:.*))*\)#', $content));

=> bool(false) (wut?) :

Now removes any of the padding/border/height property:

.f{background: url(t.png); padding: 0; border: 0; height: 0px;}

.skewX(){

}

=> works, leesslint finds errors.

$content    =   '.f{background: url(t.png); padding: 0; border: 0; height: 0px;}';

var_dump(preg_match('#\((?:(?:.*)(;)(?:.*))*\)#', $content));

=> int(0) (wut?²)

You can try with another propery after background with the same result.

I'm unable to figure out the issue, looks like an internal php bug.

What is the purpose of _escapeNonEndOfLineSemicolon ?

My test:
