A CommonMark wrapper for Laravel

Laravel Markdown

Laravel Markdown was created by, and is maintained by Graham Campbell, and is a CommonMark wrapper for Laravel. It ships with integration with Laravel's view system too. Feel free to check out the change log, releases, security policy, license, code of conduct, and contribution guidelines.

Installation

This version requires PHP 7.4-8.3 and supports Laravel 8-11.

Markdown	L5.5	L5.6	L5.7	L5.8	L6	L7	L8	L9	L10	L11
10.3	✅	✅	✅	✅	❌	❌	❌	❌	❌	❌

14.0	❌	❌	❌	❌	❌	❌	✅	✅	❌	❌
15.2	❌	❌	❌	❌	❌	❌	✅	✅	✅	✅

To get the latest version, simply require the project using Composer:

$ composer require "graham-campbell/markdown:^15.2"

Once installed, if you are not using automatic package discovery, then you need to register the GrahamCampbell\Markdown\MarkdownServiceProvider service provider in your config/app.php.

You can also optionally alias our facade:

        'Markdown' => GrahamCampbell\Markdown\Facades\Markdown::class,

Configuration

Laravel Markdown supports optional configuration.

To get started, you'll need to publish all vendor assets:

$ php artisan vendor:publish

This will create a config/markdown.php file in your app that you can modify to set your configuration. Also, make sure you check for changes to the original config file in this package between releases.

There are several config options:

Enable View Integration

This option ('views') specifies if the view integration is enabled so you can write markdown views and have them rendered as html. The following extensions are currently supported: '.md', '.md.php', and '.md.blade.php'. Additionally, this will enable the @markdown Blade directive. You may disable this integration if it is conflicting with another package. The default value for this setting is true.

CommonMark Extensions

This option ('extensions') specifies what extensions will be automatically enabled. Simply provide your extension class names here, and they will be resolved from the service container, and registered with CommonMark. The default value for this setting is [League\CommonMark\Extension\CommonMark\CommonMarkCoreExtension::class, League\CommonMark\Extension\Table\TableExtension::class].

Renderer Configuration

This option ('renderer') specifies an array of options for rendering HTML. The default value for this setting is ['block_separator' => "\n", 'inner_separator' => "\n", 'soft_break' => "\n"].

CommonMark Configuration

This option ('commonmark') specifies an array of options for commonmark. The default value for this setting is ['enable_em' => true, 'enable_strong' => true, 'use_asterisk' => true, 'use_underscore' => true, 'unordered_list_markers' => ['-', '+', '*']].

HTML Input

This option ('html_input') specifies how to handle untrusted HTML input. The default value for this setting is 'strip'.

Allow Unsafe Links

This option ('allow_unsafe_links') specifies whether to allow risky image URLs and links. The default value for this setting is true.

Maximum Nesting Level

This option ('max_nesting_level') specifies the maximum permitted block nesting level. The default value for this setting is PHP_INT_MAX.

Slug Normalizer

This option ('slug_normalizer') specifies an array of options for slug normalization. The default value for this setting is ['max_length' => 255, 'unique' => 'document'].

Usage

Facades\Markdown

This facade will dynamically pass static method calls to the 'markdown.converter' object in the ioc container which by default is an instance of League\CommonMark\ConverterInterface.

MarkdownServiceProvider

This class contains no public methods of interest. This class should be added to the providers array in config/app.php. This class will setup ioc bindings.

Real Examples

Here you can see an example of just how simple this package is to use.

use GrahamCampbell\Markdown\Facades\Markdown;

Markdown::convert('foo')->getContent(); // <p>foo</p>

If you prefer to use dependency injection over facades like me, then you can easily inject the class like so:

use League\CommonMark\ConverterInterface;

class Foo
{
    private ConverterInterface $converter;

    public function __construct(ConverterInterface $converter)
    {
        $this->converter = $converter;
    }

    public function bar(): string
    {
        return $this->converter->convert('foo')->getContent();
    }
}

app(Foo::class)->bar();

And don't forget, that's just the basics. We also support extension through listening for the resolving event from the container, and we ship with integration with Laravel's view system. You can use both the @markdown blade directive, and also using the following file extensions will compile your views as markdown: '.md', '.md.php', and '.md.blade.php'.

For example, the following are all methods of rendering markdown:

foo.blade.php:

@markdown('# Foo')

bar.blade.php:

@markdown
# Bar
@endmarkdown

baz1.md:

# Baz 1

baz2.md.php:

# Baz 2

baz3.md.blade.php:

# Baz 3

Further Information

There are other classes in this package that are not documented here (such as the engine and compiler classes). This is because they are not intended for public use and are used internally by this package.

Extensions

As hinted in the configuration docs, CommonMark can be modified using extensions. There are some very good examples in the customization section of the CommonMark docs for how to create custom parsers and renders in the customization section: https://commonmark.thephpleague.com/.

Security

If you discover a security vulnerability within this package, please send an email to [email protected]. All security vulnerabilities will be promptly addressed. You may view our full security policy here.

preg_match() expects parameter 2 to be string, array given

Hi,

I recently updated (composer update) to latest 2.0 branch on my Laravel 4.1 project and I have an issue with parsedown-extra.

Error :

ErrorException
preg_match() expects parameter 2 to be string, array given (ParsedownExtra.php line 252)

Markdown syntax with error :

###Hello world
[Link](http://google.com)

Markdown without error (no link) :

###Hello world

My composer :

"graham-campbell/markdown": "~2.0"

In my composer.lock the only difference between my production (working) and my local version (not working) is parsedown version.

Production : 1.4.5
Local : 1.5.0

Temporary fix : set parsedown to version 1.4 in composer.json

Extending Markdown syntax to add @[somelink](http://somelink.com)?

How can I extend Markdown syntax so that the following code: @[Go to Microsoft](http://www.microsoft.com) converts to a link like this: Go to Microsoft.

This is the exact same as any ordinary Markdown link works, except it has an additional '@' character immediately preceding the first opening bracket.

The reason I want to do this is for an @mention system I'm working on.

I found the issue 24 but it's still not really explained how to do it there.

Custom block parser does not advance to next line

Hello,

I made it to build a few simple extensions that a platform I am building is going to use: a couple of inline extensions for link insertion based on model ids (pages and categories of my small cms, that is); one block extension that builds a fully fledged html/js carousel.

Nothing fancy but it all seems to work pretty well except from the fact that the block extension "eats" up the text after the markers once found.

The current code looks something like this from the Parser perspective:

public function parse(ContextInterface $context, Cursor $cursor)
{
    // Save the cursor state in case we need to rewind and bail
    $previousState = $cursor->saveState();

    // Parse the handle
    $handle = $cursor->match('/(?<=\{carousel:)(.*?)(?=\})/i');

    if (empty($handle)) {
        // Regex failed to match; this isn't a valid carousel marker
        $cursor->restoreState($previousState);
        return false;
    }

    // DO SOME MAGIC TO BUILD THE CAROUSEL DATA FOR THE ELEMENT

    // Advance to the end of the string, consuming the entire line
    $cursor->advance();

    $context->addBlock($carousel_element);
    $context->setBlocksParsed(true);

    return true;
}

Anyone knows what's wrong with this? Is there a different way to properly "advance the cursor to the end of syntax indicating the block start" (as the docs state)?

I really appreciate this package but I feel like it is still missing a few better explained examples or a richer guide on the customizations. I wonder if some might have found/wrote something in this regards.

Thanks a lot!

Inline UserHandleParser

So I extended this for a UserHandleParser below but it doesn't make the changes.

<?php

namespace App\Extensions\Markdown;

use League\CommonMark\ContextInterface;
use League\CommonMark\Inline\Element\Link;
use League\CommonMark\Inline\Parser\AbstractInlineParser;
use League\CommonMark\InlineParserContext;

class UserHandleParser extends AbstractInlineParser
{
    public function getCharacters() {
        return array('@');
    }

    public function parse(ContextInterface $context, InlineParserContext $inlineContext) {
        $cursor = $inlineContext->getCursor();

        // The @ symbol must not have any other characters immediately prior
        $previousChar = $cursor->peek(-1);
        if ($previousChar !== null && $previousChar !== ' ') {
            // peek() doesn't modify the cursor, so no need to restore state first
            return false;
        }

        // Save the cursor state in case we need to rewind and bail
        $previousState = $cursor->saveState();

        // Advance past the @ symbol to keep parsing simpler
        $cursor->advance();

        // Parse the handle
        $handle = $cursor->match('/^\w+\W\w+/');
        if (empty($handle)) {
            // Regex failed to match; this isn't a valid Twitter handle
            $cursor->restoreState($previousState);

            return false;
        }

        $profileUrl = url('members/' . $handle);

        $inlineContext->getInlines()->add(new Link($profileUrl, '@'.$handle));

        return true;
    }
}

I've bootstrapped the parser into Markdown with a ServiceProvider as seen below.

    $environment = Environment::createCommonMarkEnvironment();
    $environment->addInlineParser( new UserHandleParser() );

But it doesn't parse my text case on render.

Any ideas?

Table and Raw content

On v7.0.

Using: https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#tables

| Tables        | Are           | Cool  |
| ------------- |:-------------:| -----:|
| col 3 is      | right-aligned | $1600 |
| col 2 is      | centered      |   $12 |
| zebra stripes | are neat      |    $1 |

Markdown | Less | Pretty
--- | --- | ---
*Still* | `renders` | **nicely**
1 | 2 | 3

Neither parse down, I just get them wrapped in a <p>

Example:
<p>Markdown | Less | Pretty --- | --- | --- <em>Still</em> | <code>renders</code> | <strong>nicely</strong> 1 | 2 | 3</p>

https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#html
Doesn't appear to work either, and is stripped out.

Also ~~for strikeout~~ doesn't seem to work.

6.1 appears to work for Raw.

.md Files Can Be Pre-Processed

We don't need to "execute" such files so we can "compile" them a single time.

line breaks not working

For some reason this happens:
1x -enter-: nothing
2x -enter-: new paragraph

Why isn't 1x enter a line break? Checked CommonMark spec and there it is a linebreak...
Am I overlooking something?
Thanks in advance

Image markdown is not getting compiled

Hi, Thanks for this wonderful package,

I have a problem with images, this is working fine:

! [Image] (imageLink)

but this one isn't working:

! [Image] (imageLink "Image title")

Markdown not rendered in include...

So I have the following

index.md.blade.php

@extends('layouts.base')

## This text

@section('body')

@include('bodytext')

@stop

bodytext.md.blade.php

<DIV class="container">
  <div class="row hidden-xs" id="photobox">
    <DIV class="col-xs-3 ">Photo</DIV>
    <DIV class="col-xs-3 ">Photo</DIV>
    <DIV class="col-xs-3 ">Photo</DIV>
    <DIV class="col-xs-3 ">Photo</DIV>
    </DIV>
  <div class="row">

<DIV class="col-sm-9 col-xs-12 smbotmargin" id="announcements" style="margin-bottom:10px">
<DIV id="mainstories" class="" style="border:1px solid rgba(0,0,0,.15);min-height:50px;">
  @foreach ($stories as $story)
    <DIV>
      <h3>{{$story->news_title}}</H3>
        <p>{{$story->news_body}}</p>
      </DIV>
        @endforeach;
      </DIV>
    </DIV>
    <DIV class="col-sm-3 col-xs-12">
      <DIV class="col-xs-6 col-sm-12 smbotmargin">
        <DIV CLASS="mainheadersm topround">CALENDAR</DIV>
      </DIV>
      <DIV class="col-xs-6  col-sm-12 smbotmargin">
        <DIV class="mainheadersm topround">SPONSORS</DIV>
      </DIV>
      <DIV class="col-xs-12 smbotmargin" style="">
          <DIV class="mainheadersm topround">DONATIONS</DIV>
      </DIV>
    </DIV>
  </DIV>
</DIV>

the route which it called is

Route::get('/', ['as'=>'home','uses'=>'IndexController@justShow'] );

calls

  public function justShow(){
        $stories = \AAC\NEWS_OWNERS::orderBy('start_date','desc')->get();
        return View::make('index',array('stories'=>$stories));
    }

The markdown on the index.md.blade.php is rendered correctly...

<h2>This text</h2>

but the markdown returned in the bodytext.md.blade.php is not translated.

***test body*** 
 this one kasdlkasdflkjl 
 this this again 
 and another line another line lskdfj and more and more

the above is an example of the markdown returned from the database and not translated.

Latex support

Does your package support the latex markup? If not, do you plan on adding it in the near future or do you know of any Laravel 5 plugins that offer this in a way that is just as simple to use as yours?

Markdown::convertToHtml() capital letters

It seems that Markdown::convertToHtml() converts all text to lower case.. Any fix, or reason why this happens? Thanks

Request: Ability to add classes to images.

Not sure if it's already implemented, but I can't seem to find it.

Basically, I would want to do something similar to the following

![Image](http://www.example.com/image.png class="img-responsive content-img")

It's not something that needs to be overused, but a few images require 1 attribute (img-responsive) while a few others require that one as well as another.

I know this isn't a true CommonMark implementation, but wondering if I can extend Laravel-Markdown to accomplish this, or perhaps I'm overlooking some easier way to accomplish this.

Thank you for your time.

Make Parsedown options available

For safety reasons, it should be possible to disallow scripts and other HTML elements. See the discussion at erusev/parsedown#224.

$parsedown->setMarkupEscaped(true);

This is currently not available though this Laravel wrapper around Parsedown.

Composer update/install results in "The requested package graham-campbell/laravel-markdown could not be found"

The error message:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - The requested package graham-campbell/markdown could not be found in any version, there may be a typo in the package name.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion> for more details.

Read <http://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

I've replicated this on a fresh Laravel project, here are the steps to recreate:

1. Clone laravel from Github

   git clone https://github.com/laravel/laravel markdown-test
   cd markdown-test/

2. Ensure that app/storage is writable (often causes issues on my system)

   sudo chmod 777 -R app/storage/

3. Update require in composer.json to match the following

       "require": {
           "laravel/framework": "4.1.*",
           "graham-campbell/laravel": "*"
       },

4. Run composer install

Strip function?

Any chance we could get a function to strip all markdown too? Useful for excerpts of posts, etc where you don't want the formatting showing.

Markdown can't render this {{

I don't why markdown can't render the blade syntax like.

<meta name="description" content="{{ $article->teaser }}">

The result of it be

<meta name="description" content="">

Anyone can answer what's really need to show that ?

Anchor Tags are ignored

First:
Thanks for this library!

I found a small issue, maybe you can help me out on this.
It seems like anchor-tags are ignored, or am i missing something?

Example:

[Help](#Help)
## <a name="Help"></a>Help

The anchor is missing in the output.

Thanks again
Alex

Links break render

If content you want to render contains a link e.g [Example](http://example.com), the following error is thrown:

ERROR: exception 'ErrorException' with message 'preg_match() expects parameter 2 to be string, array given' in /home/ubuntu/laravel-app/vendor/erusev/parsedown-extra/ParsedownExtra.php:228

System:
graham-campbell/markdown - v2.0.7
laravel/framework - v4.2.16

No method to escape user-inputted markdown

There's no satisfactory way to escape user-submitted Markdown as it uses the the angle bracket > for a block quote, which is escaped by Laravel into > by default.

Example:

# Title 1

<script src="example.com"></script>

> Blockquote

Escaped:

# Title 1

<script src="example.com"></script>

> Blockquote

The issue here is that the blockquote is no longer recognized as valid Markdown. One solution could be adding an escape function that ignores all right-angle brackets, which would instead convert it to:

# Title 1

<script src="example.com"></script>

> Blockquote

... which then would result in the expected Markdown, with the blockquote intact.

Table Extension integration

Thanks for this package.

Running into an issue integrating an extension.

I'm looking to use the Webuni table extension with Laravel-Markdown.

I'm adding the following to the extensions array:

Webuni\CommonMark\TableExtension\TableExtension

Which does not cause a hard crash; however, it does not render the tables within the Markdown.

Thoughts??

markdown doesn't render in a blade section

not sure if this is supported or not, or if it can be supported, but i am trying to render markdown in a blade section such as

file - welcome.md.blade.php

@extends('layouts.default')

@section('content')
    # home
@stop

when the view is rendered, it is plain text. is this by design, or a bug?

html special characters

how do you handle special characters in the md view like €

can't parse markdown table

demo

test.md contents:

# users table

id | name
---|--------
1  | Jim
2  | Lily

routes.php contents:

Route::get('/', function () {
    return view('index');
});

result

GrahamCampbell/Laravel-Markdown can parse "h1", but can't parse "table".

screenshot

PHP Requirement?

Why does this package require PHP 5.4.7? From what I can see, PHP 5.4.4 is the current stable version on Debian... and I can't imagine that 5.4.7 has some magic feature required by this package??

Suggestion for improved documentation/readme

I would suggest that the convertToHtml function is mentioned in the readme.md file. I wasn't sure if the function for converting variables was available as only the views method was described.

To make it easier for new users to decide if this is the right package - and ease development I suggest to just mention this - somewhere:

Markdown::convertToHtml($my_markdown)

Thank You

Quick Question: Trying to extend Laravel-Markdown for Block Rendering

Hi,

I'm quite new on Laravel.

I would like to add another rendering/parsing(not sure which one is the best) for Headers.
So simply, I would like to render # {Testing This Title} this to <h1 id="testing-this-title">Testing This Title</h1> (Using Laravels, str_slug helper)

There are other solutions in order to get id properties for headers. But since I'm trying to learn how to extend a package. If you could show me a starting point with a small code block, i would appreciate.

What I have read before;
https://commonmark.thephpleague.com/customization/block-parsing/
https://commonmark.thephpleague.com/customization/block-rendering/

Since I'm not sure where to add these code blockes, I'm stuck.

PS: I have also seen another Issue post here where you recommended an Emoji package but I could not extract the code I need.

Thanks in advance!

Migrate To Parsedown Extra For V2.0

What would you guys think about moving to https://github.com/erusev/parsedown in June/July 2014?

EDIT: Parsedown Extra would be cool.

Extensions

Hey,

is there an easy way to add extensions to this using the addInlineParser method? Maybe this could somehow be done using the published config?

Update title

Hi, i want to use Parsedown wrapper for Laravel 5

Is this a Parsedown wrapper or League\Commonmark as its stated in the Readme?

Disabling/enabling features

Hi,

Is it possible to disable the rendering of certain elements at the moment? My project allows my users to write markdown and I would like to disable the rendering of headings (#) and potentially others.

Cheers

Call to undefined method [package]

The same issue as this one

I'm not sure if Laravel 5 is going to preserve some backward compatibility for this. I've tried to lock my Laravel version at dev-master#846c935194a036901ba6b4397c8897fa51e19111. However, it gives me new errors like "Call to undefined function env()"...

Is it possible for you to remove the following line in @dev for now?

$this->package('graham-campbell/markdown', 'graham-campbell/markdown', __DIR__);

Thanks a lot.

Missing first line?

Markdown from my database TEXT field is being parsed successfully but I am getting some weirdness. Here's the markdown and the result. For some reason it's missing out the first headline. Any ideas?

#Hello

So here we go. How about this?

* Some bullets
* Go here

Result

<p>#Hello
So here we go. How about this?</p>
<ul>
<li>Some bullets</li>
<li>Go here</li>
</ul>

Upgrade to commonmark 0.14

I'll do this soon.

Disable safe mode temporarily

Setting safe mode to true is good idea for most cases, but sometimes it shouldn't strip HTML tags. I think convertToHTML function could have a second argument which let me disable safe mode temporarily.

Is there a possibility to do so right now?

Russian text in markdown

Used in Laravel 4 and worked fine.

Now in Laravel 5 I have some problems. Russian text with <code> renders like:
<li>Из: твоя <code>оя featu</code> ветка</li>

But must render like:

<li>Из: твоя <code>feature</code> ветка </li>

It repeats some symbols.

When in line are only english sybmols - is OK

Is it possible to have two sets of options?

Currently I have my html_input within the config/markdown.php set to true for my own writing ease, however, is there anyway to override these settings for a specific use case. i.e. So writing blog posts means I can use whatever I want, whereas a user writing a comment would only get certain abilities?

Anything like the following available?

$markdown->options([
    'html_input' => false,
    'allow_unsafe_links' => false
]);

$markdown->convertToHtml($foo);

example of use?

Hi, having never used a facade it is not clear how to use your library

an example would be great!

thanks

check UTF-8 with BOM

If md file is encode UTF-8 with BOM, the first line will not be convert. I try fix as

public function get($path, array $data = [])
{
    $bom_content = parent::get($path, $data);
    $contents = str_replace("\xef\xbb\xbf", '', $bom_content);
    return $this->markdown->convertToHtml($contents);
}

But It not working :(

Parse Markdown before parsing blade syntax?

In BladeMarkdownEngine::get() the code is as follow:

public function get($path, array $data = [])
{
    $contents = parent::get($path, $data);

    return $this->markdown->convertToHtml($contents);
}

My .md.blade.php contains @extends('layouts.default'). This means that parent::get() has already parsed my blade template and puts loads of HTML into $contents.

When convertToHtml(), which supposed to get only Markdown syntax, gets the fully parsed HTML above, it goes crazy and hence lots of <pre><code> produced.

Is it possible to specify that markdown content in .md.blade.php should be parsed before parsing the rest of blade syntax in that file? If it's not already supported would you welcome a PR that allows that?

quick question

Hi mate,
Is it possible to call the Markdown fascade directly in a controller to convert or does this package only convert files?
Thanks,
Sam

Escape for <canvas> tag

I'm not able to embed a <canvas></canvas> tag within the markdown as it seems to recognize it as text albeit not in quotes like it would normally for other text. I've noticed that when I inspect the elements using Chrome that is not highlighted the same color (purple) as other tags but rather the same coloring as text (black).

<p><canvas id="myChart" width="400" height="200"></canvas></p>

Is it possible to escape from the markdown to input the canvas tag as HTML and to return back to the markdown? I am displaying the markdown in my view.blade.php file as follows:
{!! Markdown::convertToHtml(e($post->body)) !!}

(in this example, body represents the text used for a blog entry)

_UPDATE_
"The issue is that Markdown was created long before the tag (during the HTML 4 and XHTML 1 days) and most Markdown implementations do not include that tag in their list of "block-level HTML elements." - Waylan from Stackoverflow

Not sure where to begin... would this be worth the effort to update the markdown code to have included?

Nested list hides content

Helle Graham

I'm using version 2.1.0 for Laravel 4.2, and it looks that when I'm using a nested list in my markdown file, all the content below is lost. Do you have any idea?

The weird thing is that I didn't had this problem before, I tried to reverse back to older versions, but that didn't helped either.

E.g.

* test
 * test 2
* test
 * test 2

hello

The result is that the list is shown correctly, but the text hello is missing.

target _blank for links

how this can be achieved?
