    Dompdf

    Dompdf

    HTML to PDF converter for PHP

    dompdf is an HTML to PDF converter. At its heart, dompdf is (mostly) a CSS 2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer, it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes. PDF rendering is currently provided either by PDFLib or by a bundled version the R&OS CPDF class written by Wayne Munro. (Some important changes have been made to the R&OS class, however). In order to use PDFLib with dompdf, the PDFLib PECL extension is required. Using PDFLib improves performance and reduces the memory requirements of dompdf somewhat, while the R&OS CPDF class, though slightly slower, eliminates any dependencies on external PDF libraries.

    Twemoji

    Twemoji

    Simple library that provides standard Unicode emoji for all platforms

    Twitter’s open source emoji has you covered for all your project's emoji needs. With support for the latest Unicode emoji specification, featuring 3,245 emojis, and all for free. As an open source project, attribution is critical from a legal, practical and motivational perspective in our opinion. The graphics are licensed under the CC-BY 4.0 which has a pretty good guide on best practices for attribution. Although there are two kinds of parsing supported by this utility, we recommend you use DOM parsing, explained below. Each type of parsing accepts a callback to generate an image source or an options object with parsing info. The second kind of parsing is string parsing. This is unrecommended because this method does not sanitize the string or otherwise prevent malicious code from being executed; such sanitization is out of scope.

    The warehouse's SpringBoot-based rights management system

    The warehouse's SpringBoot-based rights management system is easy to read and understand, and the interface is simple and beautiful. The core technology uses Spring, MyBatis, and Shiro without any other heavy dependencies. I have always wanted to make a background management system, and I have seen many excellent open source projects but found no suitable ones. So I started to write a background system in my spare time. So there is Zoe. She can be used for all web applications, such as website management background, website member center, CMS, CRM, OA. All front-end and back-end codes are very compact and easy to use after encapsulation, and the probability of errors is low. Also supports mobile client access. The system will continue to update some useful functions. The user is the system operator, and this function mainly completes the system user configuration. Configure the system organization (company, department, group).

    Parsedown

    Parsedown

    Better markdown parser in PHP

    Parsedown is capable of escaping user-input within the HTML that it generates. Additionally Parsedown will apply sanitisation to additional scripting vectors (such as scripting link destinations) that are introduced by the markdown syntax itself. If you wish to allow HTML within untrusted user-input, but still want output to be free from XSS it is recommended that you make use of a HTML sanitiser that allows HTML tags to be whitelisted, like HTML Purifier. In both cases you should strongly consider employing defence-in-depth measures, like deploying a Content-Security-Policy (a browser security feature) so that your page is likely to be safe even if an attacker finds a vulnerability in one of the first lines of defence. Safe mode does not necessarily yield safe results when using extensions to Parsedown. Extensions should be evaluated on their own to determine their specific safety against XSS.

    Simple.css

    Simple.css

    Simple.css is a classless CSS template to make a good website

    A classless CSS framework that makes semantic HTML look good. By classless I mean that there are no CSS classes anywhere in the CSS or the HTML. So your website can look just like this using plain old vanilla HTML. When starting a new project, I wanted a CSS framework that would get me up and running quickly, and give me something I could hack on. I got sick of all these giant frameworks that include everything but the kitchen sink, 90% of which I’ll never use. For example, the minified CSS for the Bootstrap framework is 144KB in total. By comparison, Simple.css is around 4KB. Obviously Simple.css and Bootstrap don’t compare in terms of their functionality, but Simple.css allows website developers to spin something up very quickly that looks good and needs very little work. By using something like Simple.css, provides the basics to get up and running quickly (or just use it as-is for a simple, good-looking site) yet not have to learn an extremely convoluted framework.

    HTML parser in Delphi

    A Delphi class with functions to read and dissect a HTML file

    THTMLdom is a (Delphi) class with functions to read a HTML source file and dissect it into a tree of THTMLelement. The attributes of the HTML tags are stored in the elements. Functions are provided to select elements on the basis of the attribute values or tag names. The structure of the tree can be shown and it can be rendered as plain text. The source is plain Delphi pascal, requiring a version that supports Tdictionary. There is no dependency on 3rd party units. The file to be parsed must have valid HTML4/5 tags. It is not necessary that the HTML is ‘correct’ in the sense that end tags may be wrongly placed or be absent altogether. The speed of processing (reading+parsing) is formidable: 15-40 msec per Mbyte or around 1 msec per 1000 HTML tags.

    Bootstrap Native

    Bootstrap Native

    If you are looking for Bootstrap without jQuery, this is it.

    The lighter and more compact set of JavaScript components for Bootstrap is sourced with a modern ES6+ codebase and strong TypeScript definitions. At about half the size of the original and around 12kb gZipped, this library does most of Bootstrap & Popper combined. We launched the project back in 2015 with the goal of debunking the "write less do more" myth, meanwhile the Bootstrap developers themselves have decided to drop jQuery, however, we decided to keep maintaining the project for its many benefits and the learning experience. If you mainly use Bootstrap plugins for your projects, why not use a much lighter, potentially faster library, see a different perspective on the same challenges, interact with a less crowded community, and get a better chance to learn or say hi! The Alert component covers the specific original events and public methods, but just like the original plugin, does not provide any initialization option.

It contains the content of the most recent yearly snapshot plus any finished proposals (those that have reached Stage 4 in the proposal process and thus are implemented in several implementations and will be in the next practical revision) since that snapshot was taken. This Ecma Standard defines the ECMAScript 2022 Language. It is the twelfth edition of the ECMAScript Language Specification. Since publication of the first edition in 1997, ECMAScript has grown to be one of the world's most widely used general-purpose programming languages. It is best known as the language embedded in web browsers but has also been widely adopted for server and embedded applications. ECMAScript is based on several originating technologies, the most well-known being JavaScript (Netscape) and JScript (Microsoft). The language was invented by Brendan Eich at Netscape and first appeared in that company's Navigator 2.0 browser.
