wp-less's Issues

Wiki gone?

Hi there,

You link to the github project wiki, but it does not exist.

Did you delete it?

Thank you

Automatic enqueue of style.less

If no LESS file has been spotted in the enqueue mechanism and a style.less file is present in the root directory, it should be automagically enqueued.

This behavior should be configurable through WPLessConfig class and a config constant.

WP-less does not generate new stylesheet all of sudden

I'm using wp-less as a plugin. wp-less is not generating new stylesheets - it keeps embedding in the header the last one; I deleted the folder under uploads/wp-less and did a few edits to my .less stylesheet, but still it doesn't generate a new css file and keep an old reference in wp-header to a generated css file that no longer exists; I tried deactivating and reactivating the plugin, overwriting with files downloaded from this repo, to no avail. I did not install new plugins or updated existing ones for the problem to appear. I had made few edits to a less stylesheet yesterday night and uploaded it only this morning. That's probably when the problem occurred for the first time. I reverted back the changes, but the new stylesheet is not generated any more. I tried to make the less stylesheet empty with just a single style (like body { color: red } ) to no avail.

Caching after addVariable

As i understand all css will recompiled always when using addVariable. If so, could you consider to add some caching here too? (build a array of all variables to add and check it's change or not). After changing a theme setting in want recompile once.

Cannot register LESS variables using document method in version 1.7+

In the new version of the plugin @fabrizim has set the compiler to initalize at 'init' priority 1, however the documented method for registering variables uses the functions.php file, which is executed BEFORE the 'init' action in the page life-cycle.

This results in the following error:

Fatal error: Call to a member function setVariables() on a non-object in /bedrock/web/app/plugins/wp-less/lib/Plugin.class.php on line 319

The solution was to call the variable registration with a hook after the init@1:

add_action('init', 'tws_redux_to_less_vars', 2); // The WP-LESS compiler is instantiated in 'init' priority 1.

function tws_redux_to_less_vars() {
    // Pass LESS variables from reduxlessvars option to the LESS plugin class
    if (class_exists('WPLessPlugin')){
        $less = WPLessPlugin::getInstance();
        $less->setVariables(get_option('reduxlessvars'));
    }
}

I think the plugin documentation needs to be updated to reflect this. I have a feeling other plugin components (e.g. function registration) might face a similar issue.

Issue(s) with WP Network Site and Domain mapping

As reported here: http://wordpress.org/support/topic/plugin-wp-less-issues-with-wp-network-site-and-domain-mapping

Hello, I´ve got an issue when enabling the bootstrap version for theme include, and WordPress Network Site(MU) with Domain Mapping(Free version).
It works fine before the Domain is changed(Less is compiled and css is stored), then i got error in line 96, in stylesheet.class.php, and i think the error is because of
$this->source_path = WP_CONTENT_DIR.preg_replace('#^'.WP_CONTENT_URL.'#U', '', $this->stylesheet->src);
when the new domain is mapped.

WordPress plugin repo contains .ignore files

Hi there!

Plugin .zip on WordPress repo contains .gitignore and .svnignore files in its root.
This can lead to some problems with pushing whole site repositories to production. Like this:

PHP Fatal error:  require(): Failed opening required 
'/app-root/data/plugins/wp-less/lib/../vendor/leafo/lessphp/lessc.inc.php'
 ...   in /app-root/data/plugins/wp-less/lib/Plugin.class.php on line 48

It might be a good idea to remove them, if that is possible, to skip rare but unnecessary problems.

Cheers!

Cache path convention changed

As detailed in this commit: b13596f

Some changes were made to configurePath() in lib/Stylesheet.class.php that breaks the previous caching convention. The cached css files were previously stored under wp-content/uploads/wp-less/[theme]/ (where [theme] is equivalent to the theme folder name in use). However, since the aforementioned commit, the addition of basename() is causing the [theme] path portion to be stripped, since basename() returns nothing if the file doesn't already exist. Cached stylesheets are now being placed under wp-content/uploads/wp-less/, instead.

Anyone who was depending on that convention for relative paths from the cached stylesheet to other things, such as FontAwesome, will find that those components now quietly break.

wp-less in Admin Area

Hi,

it seams to me that the plugin is not working in the admin area, or I'am doing something very wrong.

The problem is that the Plugin does use the "wp_enqueue_scripts" Action what is ok for the non-admin part. But in the admin area the hook should be "admin_enqueue_scripts".

I have tried some stuff and ended up doing this:

$less = WPLessPlugin::getInstance();
add_action('admin_enqueue_scripts', array($less, 'processStylesheets'), 999, 0);

in a function due to the init action. That works but is kind of ugly.

Is there a more easy solution to get wp-less working in the admin area?

Caching check not working...

wpless is in deep mode.... but caching keeps creating new files... even when no changes are detected... any idea why?

Update lessphp to 0.5.0 for imported variable override fix

leafo/lessphp#302

Ran into this one today and it appears to be fixed in the latest release 0.5.0

'Always' and 'Deep' recompile options not working.

I don't know why, but for me, those two options are not working. Maybe you could give me a tip on how to find out why.

I have added WP Less to my theme functions.php:

$less = WPLessPlugin::getInstance();
$less->dispatch();
$less->install();

Will wp-less work with add_editor_style?

Is there a way to compile LESS files via add_editor_style? I need it to compile LESS for me to improve the visual editor style easier.

Admin Panel: Strategy Configuration

Same as #1 but from the admin side, not code side.

update lessphp with latest build (corrects issue with interpolation inside of selectors)

After updating Bootstrap I had an error thrown by wp-less/lessphp similar to that experienced in this ticket leafo/lessphp#376

this commit fixes the issue leafo/lessphp@ee5b675

however I think that is not yet updated inside wp-less

I fixed the problem by manually upgrading the old phpless with the newest build from the github repo

Passing variables to PHP before compile

Hi there. I am really enjoying using wp-less. However, there is a niggle:

I am trying to make individually styled pages through use of custom categories, meta fields, what have you.

The way I've done this in the past is to basically generate in-line CSS with PHP, based on what the $vars of the page are set to.

I have been trying to pass vars to wp-less for quite some time now, from header.php to functions.php, but have had no luck. Using my_less_vars(), add_var(), the $less->addVariable() method, etc have yielded no luck.

Manually changing the variables.less file to change colour values results in immediate change. But I want to do it as the page renders.

I am using the twitter bootstrap less framework, and enqueuing only bootstrap.less, which as you probably know @imports a whole bunch of .less files, one of which contains the relevant values: variables.less

Am I getting this ass backwards, or is something wrong? I am on a fresh install of WP 3.7.1 on Dreamhost. WP-less is the only plug-in installed.

moved WP to a new server.. now have less problems..

so after I moved over my WP, via a cloner.. the less files started spitting out this error..

lessphp fatal error: load error: failed to find D:\Hosting\4926382\html\cdpinew/wp-content/themes/theme2126/bootstrap/less/bootstrap.lesslessphp

fatal error: load error: failed to find D:\Hosting\4926382\html\cdpinew/wp-content/themes/theme2126/style.less

this theme uses less built into it.. its trying to access the files via the old location on the previoius server.. how do i clean this up??

how to use on admin side?

How would I use less stylesheets for backend styling? I have wp_enqueue_stlye() in an 'admin_enqueue_scripts' action, which doesn't seem to work. Any advice much appreciated. Thanks!

unit() function doesn't seems to parse

Hi oncletom! Nice job with this wp plugin, it's pretty funny to develop in this way-

Neverthless i couldn't get work unit() function. There is what i'm trying to do:

.fontsize( @size ) {
  font-size: unit( @size, px );
  font-size: unit( @size / @rembase, rem );
}

@rembase is previously defined. When i use this mixin .fontsize(14) i get this output:

font-size: unit( 14, px );
font-size: unit( 1, rem );

According to Less Function Reference the output it's supossed to be

font-size: 14px;
font-size: 1rem;

I'm not sure if that is a bug or unit() function is not supported yet in wpless.

Thanks you so much!

non-less files are being removed in the mce_css filter.

All regular .css files are being removed in the mce_css filter. I am adding this issue for posterity, as I just resolved it with this commit: e56b037

I think this patch may warrant an updated package for public consumption.

Prevent wordpress show blank page, when less issue

Today I wrote a little issue in less saved the file and then I got a blank wordpress page.

There was no error and no hint.

Please fix that.

Thank you

WP-LESS does not work on Wordpress 3.6!

There's not much more I can say, I don't know what's broken but it's not working on 3.6

Removing chmod call

Because it is unnecessary and cause troubles on some hosting install.

Deal with GIT + SVN (to push on official repo)

Most important thing to do, it's slowing contribution and plugin evolution.

Compressing CSS Output

I should probably open a pull request for this but I'm not sure how many others want/need it. In Plugin.class.php around line 43 I added this to the construct...

$this->compiler->setFormatter('compressed');

It ecentially minifies the css output. It didn't make a huge difference on file size for me but I figure every k counts!

So, to recap, line 43....

        $this->compiler = new WPLessCompiler;
        $this->compiler->setFormatter('compressed');
        $this->compiler->setVariable('stylesheet_directory_uri', "'" . get_stylesheet_directory_uri() . "'");
        $this->compiler->setVariable('template_directory_uri', "'" . get_template_directory_uri() . "'");

It's easy to read the output css file without this obviously but better to have this for mobile reasons.

Add ability to configure the lessphp formatter used

I'd like to use the compressed formatter in lessphp to get a minified output, but there seems to be no way to access the WPLessCompiler instance to call setFormatter.

URL Resolving

IE seems not to like ../ notation in URL paths.

When having a folder called /less/ and another called /img/ the CSS for a background image becomes /default-theme/less/../img/my-image.png. Internet Explorer don't like the /../. Maybe replace it with the folder name instead? Else the less-file must be in the theme root.

wp-less since version 1.6.0 fails on production

Part 1:
I have version 1.6.0 running just fine on production at betterplace.org/c/.

Whenever I update to the latest (current 1.7.5) I get this error on production:

Warning: require(/www/static.asdf.com/releases/20141124155319/wp-content/plugins/wp-less/lib/../vendor/leafo/lessphp/lessc.inc.php): failed to open stream: No such file or directory in /www/static.asdf.com/releases/20141124155319/wp-content/plugins/wp-less/lib/Plugin.class.php on line 48 

Fatal error: require(): Failed opening required '/www/static.asdf.com/releases/20141124155319/wp-content/plugins/wp-less/lib/../vendor/leafo/lessphp/lessc.inc.php' (include_path='.:/usr/local/lib/php') in /www/static.asdf.com/releases/20141124155319/wp-content/plugins/wp-less/lib/Plugin.class.php on line 48

I get this error regardless of the .gitignore files from part 2, below.

Any ideas??

Part 2:

Also, I have issues with the .gitignore files that the plugin downloads automatically.
(I have all my WP Code in a private repo and deploy via capistrano.)

There is a difference between what I check in when I keep the .gitignore files in the plugin folder to the version when I ignore the .gitignore-plugin files.

Adding Admin Panel

As received from email feedback, an admin panel could be nice.

Features are detailed in other issues.

WP Engine Compatibility

I am using WP Engine as my host, and I've been having trouble getting WP-LESS to work since upgrading to 1.5.1.

According to the WP Engine engineer I've consulted, their server configuration won't allow the chmod() operation WP-LESS implements when writing the generated CSS files to the assigned upload directory.

But prior to the 1.5.1 release WP-LESS was working fine with WP Engine, and it looks to me like chmod() was used at least as far back as 1.4.2.

So, I'm not sure we've pinpointed what changed in 1.5.1 that's causing the issue. Anyone else out there having the same problem? Any ideas?

i can't get the right instance of WPLessCompiler in WPLessPlugin

I try to add https://github.com/oyejorge/less.php to compile, see also https://github.com/bassjobsen/wp-lesscss

in my functions.php i define:

if (class_exists('WPLessPlugin'))
{
    $less = WPLessPlugin::getInstance();
    $less->addVariable('myColor', 'purple');
}

with addVariable in WPLessPlugin:

    public function addVariable($name, $value)
    {
        $this->compiler->parse('@'.$name.': '.$value.';');
    }

and

class WPLessCompiler extends Less_Parser
{

}

$this->compiler->parse seems to set Less_Parser->rules but will be reset after every call to addVariable();
Calling $this->parse() inside Less_Parser->getCss() works as expected.
For me it seems addVariable creates a new instance of WPLessCompiler every time and i don't understand why.
Hope you can help.

Little Error and Improvement ideas in /lib/Compiler.class.php

If I am not wrong the Second Line in the Compiler.class.php is useless.

<?php
$compiler = 'lessphp';
if( defined('WP_LESS_COMPILER') ){

The $compiler variable is never used again, is it?

Secondly, would it not been better to register a filter hook to let programmers change the folder with the compiler class base, instead of using globals?

Also would it not been better to encapsulate the checksequence for the includepath inside some other class? This plugin is nicely done in OOP but that look outside the norm.

I just used to switch from lessphp to less.php 'cause lessphp does not compile the "Semantic Grid System" less files right.
Was nicely surprised that switching the compiler class was soo easy! :)
Many thank!

Symlink to the latest compiled CSS file

Have to think if we deal with symlinks (won't work for Windows) or if we create another copy of the file.

Scheduled Events clog up Database and Break Site

Hi there,

There is an issue I keep hitting where the cron value in wp_options get's so big that the site no longer operates.

I believe this could be due to an issue mentioned at https://codex.wordpress.org/Function_Reference/wp_schedule_event

'For some reason there seems to be a problem on some systems where the hook must not contain underscores or uppercase characters.'

The issue causes the hook to be repeatedly added to the serialised array,

Doesn't work with multisite

Hi,

I'm getting errors when I'm using WP-LESS with WP multisite. I've created a fix for it:

Replace line 87 in "Stylesheet.class.php" from:
$this->source_path = WP_CONTENT_DIR.preg_replace('#^'.content_url().'#U', '', $this->stylesheet->src);
To:
$this->source_path = WP_CONTENT_DIR.str_replace('/wp-content','',parse_url($this->stylesheet->src,PHP_URL_PATH));

It would be nice if you change this in a feature version.

wp-less fails under https

As seen here http://wordpress.org/support/topic/wp-less-fails-under-https

Upgrade to lessphp 0.4.0

And bump the plugin version to 1.6.0 as it's possibly breaking things.

Admin Panel: Prune Cache

Button to invalidate global LESS cache.

Parsing error with latest version of twitter bootstrap

For problem description see: leafo/lessphp#208

I upgraded phpless to the latest version (0.3.5) and that fixed the issue.

Adding a Cache Invalidation strategy

As received feedback, using WP_DEBUG is not a good strategy on live servers, as we may need an always rebuild cache without being in debug.

These rules are interesting:

On file expiry;
Only for logged in users;
For every pages.

Either to choose that from a constant + bitmask, or many constants.

Not Compiled in Localhost

i run wordpress in my computer (using EasyPHP), and i download themes that include less files.

in the documetation, everything just click and will be done. but when i finished install the themes, not single one of css in the less folder that compiled.

i try to upload it on server, web hosting i mean. It's ok, nothing error, all less files compiled well.

i think it was my EasyPHP that error, but it's not. i try to download EasyPHP again, but it's still not compiled.

maybe it's because i run it in localhost?

(ALREADY SOLVED) NOT WP LESS BUG, THE PROBLEM IS IN EASYPHP

Unable to use raw filepath with `wp_enqueue_style('foo', get_stylesheet_directory().'bar.less')`

When attempting to enqueue a LESS stylesheet with the wp_enqueue_style('foo', get_stylesheet_directory().'bar.less') method, I'm getting a PHP error as follows:

PHP Warning:  filemtime(): stat failed for /Applications/MAMP/htdocs/mysite.com/content/Applications/MAMP/htdocs/mysite.com/content/themes/my_theme/assets/less/bar.less

I'm pretty sure there is a conflict between some folder / WordPress structural re-writes that I'm doing and the expected schema of the plugin - notice how (the above error is being thrown from local development in MAMP) the filepath is duplicated above: /Applications/MAMP/htdocs/mysite.com/content/Applications/MAMP/htdocs/mysite.com...

Any idea how to make that filepath for wp_enqueue_style() absolute? Note that my other enqueue style calls are working fine for other CSS and JS, only the one for the .less file as directed through this plugin is causing a problem.

url() not resolved correctly

I had the issue that only the "stylesheet_dir"-part of a converted "url()"-path was displayed, not the filename or any parts put into the parantheses.

Solution was in function _filterStylesheetUri() (Plugin.class.php)

$matches wasn't associative, but rather numerical array. so, $matches['url'] etc returned nothing; replacing by $matches[2] works now.

Maybe this is actually just an issue of that hosting provider, but just for the record...

PHP Version 5.2.6-1+lenny6

Add the possibility to combine multiple files into one compiled css

wp_enqueue_style('theme-main', get_stylesheet_directory_uri().'/stylesheets/theme-main.less');
wp_enqueue_style('theme-extra', get_stylesheet_directory_uri().'/stylesheets/theme-extra.less');

---> combine-main-extra.css

wp-less + option-tree

That sound quite good, but how could I get my options from options-tree to wp-less?
This works just fine:

<?php
if (class_exists('WPLessPlugin')){
    $less = WPLessPlugin::getInstance();

    $less->setVariables(array(
        'fontcolor' => 'red'
    ));
}
?>

Now, Option-tree's docs says:
If you've integrated OptionTree directly into your themes root directory, you will not need to wrap your code with function_exists, as you're guaranteed to have the ot_get_option() function available.

So, I'm trying this:

<?php
if (class_exists('WPLessPlugin')){
    $less = WPLessPlugin::getInstance();
    $less->setVariables(array(
        'fontcolor'   => ot_get_option( 'fontcolor' )
        ));
}
?>

And getting Fatal error: Call to undefined function ot_get_option()

I'm using Option Tree Plugin in Theme Mode.

Admin Panel: File Grid

The grid would present the state of each file cache, and if a theme LESS file is newer.

It could hint a manual refresh.

Problem with Comments in output file

Hey,
I'm using wp-less, and all comments in generated css's are eliminated, how can i set it to output comments?

Install Documentation

Hi,

In the later versions the install procedure have changed noticeable. Can anyone write a documentation how to install this Plugin via git and composer?

Also how to update guide the plugin when installed via git and composer would be nice. I find myself in a position needing something like that...

Thanks a lot!

Adding Functions

Hi there great work and great to see 1.5 coming along... I have the framework bootstraped within my theme... is there any hooks I can get into to do a proper registrer function call to add my own lessphp functions?

Thanks so much (see lessphp example below)

<?php
include "lessc.inc.php";

function lessphp_double($arg) {
    list($type, $value) = $arg;
    return array($type, $value*2);
}

$less = new lessc;
$less->registerFunction("double", "lessphp_double");

// gives us a width of 800px
echo $less->compile("div { width: double(400px); }");

PHP Warning: unlink in GarbageCollector

We are using wp-less as a part of our theme (not installed as a plugin) and we noticed that Apache error log has thousands of errors like:

PHP Warning: unlink( [path here]): Is a directory in [path here]/plugins/wp-less/lib/Garbagecollector.class.php on line 118

Although the plugin works - our error log contains literally thousands of these warnings. Can you point us to the solution?
