duncansmart/less.js-windows

A way to run the LESS.js compiler in windows

LESS.js for Windows

A standalone version of the LESS command-line compiler that will run on Windows with no other dependencies.

Consists of a standalone version of Node.js and the required less.js files/dependencies.

Install

Download and extract the release ZIP and invoke lessc.cmd as detailed below.

Usage

Basic usage:

lessc  path\source.less  path\output.css

Compress CSS:

lessc  --clean-css  path\source.less  path\output.css

For full usage:

lessc -h

History

Previously the project used the Windows Script Host cscript.exe as its runtime. Over time this was proving to be diffcult to support as it was essentially using the browser-based version of less.js and stubbing out objects like window and document to mimic the browser environment. This version is still available in the windows-script-host branch.

less.js-windows's Issues

Imported Less File, Appends Sub-Directory to url() styles

When building the less files with the following directory structure:

Styles
Styles/Home

With main less at root of Styles and import less files in home, I would get the following result for every background-image: url().

background-image: url('Home/Home../Images/Image.jpg");

from the original:

background-image: url("../Images/Image.jpg");

I do not know why it is prefixing these items, but it is stopping me from being able to use sub-directories for my less compilation.

Not sure if this an issue with Less.js or the windows Script.

missing module when --clean-css used

I just upgraded to your latest ver (from the zip). Default usage works fine but --clean-css (as in the README) fails:

t:\dev\less.js-windows>lessc --clean-css x:\x.css
Error: Cannot find module '../images/url-rewriter'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Module.require (module.js:364:17)
    at require (module.js:380:17)
    at Object.<anonymous> (t:\dev\less.js-windows\bin\node_modules\clean-css\lib\imports\inliner.js:4:19)

    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Module.require (module.js:364:17)

Same if I use node.exe directly.

Remove Read-Only flag from css files

Hi

The following revision to the .wsf file removes read-only flags from css files to stop the script bombing out. This is particularly relevant for those of us using TFS. This is my first time in GitHub, so I apologise for not submitting the code properly, but I have no idea how to.

It checks for the existence of a file before checking and removing its read-only flag in the convert method.

Regards

Jared

Docs wrong

--clean-css options does not work. I get the following output:

"Unable to interpret argument clean-css - if it is a plugin (less-plugin-clean-css), make sure that it is installed under or at the same level as less"

Using the '&'-operator after a subselector doesn't work as expected

Using the ‘&’ operator after a selector doesn’t work properly. In the output the ‘&’ parts get places before the subselector instead of after it:

#main {
    #content {
        .class {
            position: absolute;
            #container & {
                position: relative;
            }
        }
    }
}

Should output:

#main #content .class { 
    position: absolute; 
}
#container #main #content .class { 
    position:relative; 
}

But this is what it does output:

#main #content .class { 
    position: absolute; 
}
#main #content .class #container { 
    position: relative; 
}

Note: this usage of the ‘&’-operator isn’t documented. In the documentation it only shows the operator being used before a selector. However, it does work when trying this example in the browswer.

Relative paths in imported files do not work correctly

When importing a less file the less.js changes the relative paths in that file so they will still work. Example:

File structure:

main.less
    imports
        subdirectory
            import.less

main.less:

@import "imports/subdirectory/import";

import.less:

.example {
    background-image: url('../images/bg.gif');
}

Expected output:

.example {
    background-image: url('imports/subdirectory/../images/bg.gif');
}

But it becomes:

.example {
    background-image: url('imports/subdirectory/imports/subdirectory/../images/bg.gif');
}

Edit:
The behavior changed in less.js version 1.1.5, but is still wrong.

Edit2: The behavior is back to the original issue again, since the hotfix of 1.1.5. Updated the example above.

Mixin url paths not being transformed based upon import

I am coming from dotless and I am not sure if it was something specific to that but if I had a base mixin file and any urls were included within there, any subsequent imports of the mixins would correct the paths based upon the import statement.

So for example if I had the following:

• root
  • images
    • background.jpg
  • mixins.less (has mixin called .with-background which references url images/background.jpg)
  • themes
    • default
      • default.less (imports mixins.less and uses .with-background)

In the above example the default.less file will be using the following url for the image:
root/themes/default/images/background.jpg
rather than what it should be:
root/images/background.jpg

So is there a way to hint paths or some pattern to handle this use case?

doesn't work on win8 pro

I set the PATH variable with the less.js-windows directory and installed the LESS2CSS ST2 plugin, but when I try to compile the .less to css a prompt window appears and immediately stop working and nothing is done.

I"m getting Error 1, any ideas what that is?

I'm executing this through wscript, eg. errCode = oScript.Shell.Run(path,0,true) and it's returning error code 1. (path = %comspec% /c c:\less\lessc.cmd c:\mystuff\less\styles.less c:\mysuff\css\styles.css). Running interactively at a cmd prompt doesn't throw an error, but the everyone group has modify on all these paths just for testing.

not generating css file

I apologize if I am missing something, but I can't seem to get WinLess to actually create the CSS file. It shows a success compiler result, but no css file is created that I can see.
I am pointing it at a directory with a single less file in it - square-media-grid.less.
Thanks, d

404 Issue

If I run the command lessc test.less anything.css I get the following:

ERROR:
   name: Error
   description: Couldn't load test-import.less (404)
   message: Couldn't load test-import.less (404)

I can see that you're using AJAX requests through the WSF file and using cscript to compile it for use locally. I'm running the following command:

lessc test.less rar.css

The "test.less" file is definitely in the same directory as when I call it.

Any ideas?

Add shell=True for subprocess.Popen when compiling less.

It would be nice if there is no cmd window flash when compiling less.

Permission denied?

I'm trying to use this as a drop in replacement for lessc in Django with django-compressor, and I get the traceback below. Running the lessc.cmd with the same arguments seems to work find. Any suggestions?

Documentation missing path to test files.

The documentation currently says to test everything is working, use:

C:\code\lessc-wsh>lessc test.less

This should be:

C:\code\lessc-wsh>lessc test/test.less

Wrong result of compiling property 'calc'

When I'm trying to compile property calc(), I'm getting it modified.
For example:
calc(100% - 40px) => calc(60%);

Node.js, NPM and lessc now work on Windows

Hey Duncan,
I recently found out that Node.js, Node Package Manager and lessc now work on Windows. Installing and using LESS this way is very easy. I updated the less.js Github page about command line LESS tools with this information.
When I have more time I will update WinLess to work with lessc instead of your (awesome) script.

Maybe you should update your blog post and the readme of this project to reflect this change?

Cheers,

Mark

Output is empty file

Perhaps I have too many files or too large files but it says "FATAL ERROR: CALL_AND_RETRY_2 Allocation failed - process out of memory" ... the node.js stops around 750K memory, system has 12 Gig of memory.
How can I allocate more memory?

File Watcher

How would I go about setting this up to watch less files for changes and then save out a compressed css file?

Is it possible to add an option to lessc to print the generated content on stdout (console)

Hi

Is it possible to add an option to lessc to print the generated content on stdout (console) instead of always writing to a file.

Regards,
Lubomir

IE hacks problem

Hello

I have a problem with IE hacks with arguments

Example:
@radius: 20px;

.test {
border-radius: @radius \9; //throw error
border-radius: 20px \9; //everything is ok
}

Do not normalize rootpath option as it is a URL

Issue #1234 from less.js can be fixed in the same way on this project.
See:
less/less.js@285f4ac

When an '@import'-ed file is empty, further '@imports' are not processed

I have tested this with the newest version of your script + version 1.1.4 of less.js.

main.less:

@import "imports/import1";
@import "imports/import2";

imports/import1.less : empty
imports/import2.less:

.import2{
    height: 55px;
}

No errors are thrown, but the output file test.css is empty. If a comment is added to import1.less (either a css comment or a less comment) import2.less does get proccessed.

'"F:\less.js-windows-master\bin\node.exe"' 不是内部或外部命令，也不是可运行的程 序 或批处理文件。

After input lessc , error.
Path is right.
What can i do ?
Thanks.

Upgrade request: Less 1.5.0

Any plan on upgrading to LESS 1.5.0 in near future ? Sourcemap support is a great and much needed feature (at least for me)

add license file

license file is missing from the repo.

Update request: 2.1.1

Hello! I'm working sometimes on my school computer in which I cannot install anything, your package helps me a lot however being stuck on 1.7.5 which is rather old now doesn't suit my needs (I use partial files which do get compiled with your 1.7.5 package)

Thanks!

LESS-1.3.0

Trying to compile a .LESS file that was working with LESS-1.2.2 with LESS-1.3.0 and I now get the following error:

ERROR:
type: Syntax
message: 'eval' is null or not an object
filename: ..\app\vendors\bootstrap\less\bootstrap.less
column: -1
extract: ,, * Bootstrap v2.0.2

It's working fine if I use LESS-1.3.0 directly in my html file, so I know the .LESS file has no error. Could this be related to the way the .swf file calls less?

Thankx

Circular @imports cause silent failure

If file01.less @imports file02.less and file02.less @imports file01.less, then lessc.cmd silently fails.

In my case, removing the circular dependency got me back in working order.

Runtime error with empty files

If I want to compile an empty file, I got the following error "lessc.wsf(22, 14) runtime error microsoft jscript: Input past end of file"

problem with @import

import works fine with .css files, but it fails when using .less files via lessc.wsf and XMLHttpRequest.prototype

@import url(test.less);

@color: #4D926F;

header {

color: @color;
}
h2 {
color: @color;
}

Machine friendly error output format

It would be nice to have an ability to have information about errors in machine friendly output format.

It would be ideal to have all information about a problem within only one line so a program could easily parse whole output line by line.

For example it is done in Dart. There is a --format:machine flag for that purposes.

no error displayed on erroneous @import file

Erroneous .less file added by @import do not generate error on processing.

新需求

我希望less可以变成成紧凑型的代码，如：

nav ul{margin:0;padding:0;list-style:none}
nav li{display:inline-block}
nav a{display:block;padding:6px 12px;text-decoration:none}

@import (inline) doesn't work

Hy,

i used @import (inline) for a css-file, that i want to include in my code.
But less.js-windows give me this error:

SyntaxError: expected ')' got 'i' in file.less on line 2, column 10:
1
2 @import (inline) 'file.css';
3

is there any workaround?

Docs are wrong & this is broken

I can't get this to work at all. I just receive errors and the docs don't include anything to help.

First, running the command lessc with any options causes this error after initial download:

'"C:\less.js-windows\bin\node.exe"' is not recognized as an internal or external
command, operable program or batch file.

If I run the build script included with this I receive errors:

Downloading latest node.exe

Repeating my styles 5 times

I’m using the less-1.3.0.js to compile my main.less file, but the result is strange and i’m not figuring out how to fix this problem.

The problem is that the content of my main file is repeating 5 times, when compiles it does the imports of the files ok.
For example:

@import “less/bootstrap.less”; //add the compiled content OK

all my styles here // repeates 5 times

——-
I done some tests like. My file have 435 lines and repeats 5 times my styles, with 434 lines it works ok.
There is some characters/size/lines limitation for the compiler?

wsf folder compile issue

I'm getting the following error when I try to compile a folder:
lessc.wsf(107, 27) Microsoft JScript runtime error: 'e' is null or not an object

folder contains some *.less files,
files are compressed: sometimes all of them, sometimes all except the last one.
all files are valid and contain no errors and I can compile them all separately with no issues.

I've tried to debug the lessc.wsf file and it seems that when enumerating files in some cases "e" becames null which breaks the script...

I couldn't figure out why.

can not convert less functions for strings

i have a less file with some less functions,but i suffered error report when i save my less file.

for test:
body{ %("repetitions: %a file: %d", 1 + 2, "directory/file.less"); }

it report:

ParseError : unrecognised input error in ......
