    TOML

    TOML

    Tom Preston-Werner's obvious, minimal language

    Tom's Obvious, Minimal Language. By Tom Preston-Werner, Pradyun Gedam, et al. TOML aims to be a minimal configuration file format that's easy to read due to obvious semantics. TOML is designed to map unambiguously to a hash table. TOML should be easy to parse into data structures in a wide variety of languages. TOML shares traits with other file formats used for application configuration and data serialization, such as YAML and JSON. TOML and JSON both are simple and use ubiquitous data types, making them easy to code for or parse with machines. TOML and YAML both emphasize human readability features, like comments that make it easier to understand the purpose of a given line. TOML differs in combining these, allowing comments (unlike JSON) but preserving simplicity (unlike YAML). Because TOML is explicitly intended as a configuration file format, parsing it is easy, but it is not intended for serializing arbitrary data structures.

    Configuration markup language

    Human readable and human writable format for the config files

    For object-oriented programs is useful to supply the configuration information in structured manner also. Seems the XML is the an answer. But too much <tag></tag> everywhere make the XML for *.config or *.ini files almost human unreadable and uneditable. This library intended to read text of markup configurations files in uniform way. Text information from the file is loaded by your program as a structural tree. After slurping a *.config file we can supply the resulting objects to object instances of our program to let them configure themselves. So, it facilitates text information to supply configuration data to object-oriented software. Advantage - we can use markups to mark just the groups of the parameters only. And we do obliged not to keep markups for the every Name=Value pairs like XML does. Such text in *.config file is less messy, and much more human readable then XML.

Open Source Markup Languages Guide

Open source markup languages are computer languages used to create the structure and presentation of any type of document, including those used on websites. They are text-based and use symbols (markup) to describe different parts of the document in order to differentiate between the content, such as text or images, and how it is presented. The most commonly used open source markup language is HTML (HyperText Markup Language).

HTML is what web developers use to organize and present web pages all over the internet. It was created by Tim Berners-Lee in 1990 as a way for scientists at CERN, a large particle physics laboratory in Switzerland, to be able to share information with each other quickly and efficiently. HTML uses tags in angle brackets (<>) that specify the various sections of a website for search engines like Google so that they can read them more easily. These tags also allow you to do things like add links from one page to another – this is where hypertext comes from.

Another common open source markup language is XML (Extensible Markup Language). XML was designed in 1996 by an international consortium of tech companies called W3C (World Wide Web Consortium) as a way for websites to exchange data between each other without relying on formats specific only one program or platform. This means that any program can generate or recognize XML which makes the language incredibly powerful. Unlike HTML which has specific tags assigned certain looks, styles and functions, XML allows users to define their own set of tags making it much easier for developers when creating custom systems or applications that have unique requirements not covered by standard HTML elements.

CSS (Cascading Style Sheets) is another widely used open-source markup language but instead of defining how content looks when it’s displayed onscreen (like HTML does), CSS determines how content should look when printed out on paper or through another medium such as an audio player. It does this by setting rules about font size, color, line spacing etc., for different types of output devices. Finally XSLT (Extensible Stylesheet Language Transformations), which works similarly but with XML documents rather than plain text documents like those written in CSS or HTML files - allowing developers immense control over how their data can be processed and presented visually across multiple platforms/devices simultaneously.

Open Source Markup Languages Features

  • Extensibility: Open source markup languages provide developers with the flexibility to extend existing tags and even add custom elements. This provides more control over the structure and appearance of webpages.
  • Cross-Platform Compatibility: Open sourced markups allow developers to create websites that can be accessed on multiple platforms without needing to make any modifications or have a separate version for each platform.
  • Community Support: Since open source markup languages are created by community members, any issues found in them can easily be fixed and improvements can quickly be implemented. Additionally, community members often offer free tutorials and resources regarding how to use the language.
  • Easy Readability: Due to their simple syntax, open source markups are generally easy for anyone to read and understand regardless of whether they have coding experience or not. This makes it easier for both developers and users alike to use them without having to struggle with overly complex code structures.
  • Standardization: As most of these languages rely on standardized HTML tags, they provide a common foundation between all websites using them which makes development more efficient since features do not need to be recreated every time.

Types of Open Source Markup Languages

  • HTML: Hypertext Markup Language is used to create webpages and is the standard markup language for websites. It contains short codes or tags that are inserted into webpages to format text, images and other content.
  • XML: Extensible Markup Language follows a set of rules for encoding documents in both human and machine-readable forms. It can be used to store data, as well as describe and transmit information across different platforms.
  • CSS: Cascading Style Sheets contain instructions that tell the browser how to style elements on a webpage (fonts, backgrounds, colors). It makes website creation easier by allowing styles like font size, color and layout to be specified in one single place instead of each page individually.
  • YAML: Yet Another Markup Language is an expressive data serialization language commonly used to write configuration files that are easy for humans to read and edit but also parsable by machines. Its syntax includes indentation levels used instead of braces or brackets as well as inline lists/dictionaries similar to JSON format.
  • Markdown: Popular among bloggers and writers who need lightweight formatting tools quickly accessible from any plain text editor; it uses punctuation characters for most formatting tasks (**bold** for boldface text, *italic* for italics). The goal with markdown is speed and readability paired with ease of use.

Advantages of Open Source Markup Languages

Open source markup languages provide numerous benefits to their users. These include:

  1. Flexibility: Open source markup languages allow for the user to customize the webpage desired. With open source, developers and webmasters have access to all of the code needed to create, edit and maintain a website. This gives them a greater degree of control over how their website looks, functions and behaves than they might otherwise have.
  2. Cost-Effectiveness: Many open source markup languages are offered at no cost or with nominal charge. That means developers can take advantage of powerful web development tools without incurring any up-front costs or having to pay ongoing subscription fees.
  3. Ease Of Use: The syntax used in many open source languages is designed with a focus on ease-of-use making it easier for people new to programming to get started quickly and produce stunning results more quickly - particularly when compared to traditional programming techniques like Java/C++/PHP etc. The underlying code is often well documented so that even experienced developers can quickly find answers should problems arise.
  4. Reliability & Security: Open Source software is generally regarded as more reliable due largely to its wide distribution base which encourages “peer review” of code by members of the community leading towards better quality assurance overall. Also, because bugs can be identified and repaired easily (due again largely in part due to peer review) there is less incentive for malicious actors looking for potential vector points from which they could hijack computers running different versions of proprietary software as they would be able detect any vulnerabilities present much sooner within widely used versions available online versus versions released only through commercial vendors who may not issue patch notifications or fixes until after an attack has taken place. Additionally, since developers possess complete control over the codebase, they can perform rigorous testing before releasing any updates into production environments further minimizing security risks posed by unknown sources offering potentially untested new features/functionalities added in subsequent releases from other vendors who may be unable or unwilling invest adequate time into proper testing cycles prior launch dates.

Types of Users That Use Open Source Markup Languages

  • Content Writers/Authors: Content writers create content using various open source markup languages like HTML, XML, and CSS for websites, blogs, manuals, and documentation.
  • Web Designers/Developers: Those who design and develop websites use these open source markup languages to build the front-end of the website. They make sure the website displays properly on all devices.
  • Software Programmers: Programmers use open source markup languages to write code for various applications such as mobile apps or software programs.
  • Graphic Designers: Graphic designers use HTML5 to create interactive web designs with animations, videos, audio clips etc. They also embed rich media in different parts of a webpage or an application.
  • Database Administrators: Database administrators take advantage of XML to store data in its raw format which can be later accessed easily by other applications across multiple platforms.
  • Game Developers: Game developers know how to incorporate JavaScript along with other open source markup languages into game development process on popular gaming consoles or PC platform games.

How Much Do Open Source Markup Languages Cost?

Open source markup languages are free of cost for everyone to use, so there is no monetary cost associated with using them. However, many open source markup languages require some level of programming knowledge and can take a significant amount of time to learn if you don’t already have coding experience. Additionally, there may be costs associated with hosting the files and other elements necessary for your project that make use of the open source markup language. Depending on the complexity and quantity of the project, these costs can vary greatly but could potentially include server fees, bandwidth usage fees, additional development or scripting resources needed for custom integrations or modifications, etc. Therefore although the initial cost for open source markup languages is zero dollars upfront, there may be additional expenses incurred in order to successfully deploy projects utilizing them.

What Do Open Source Markup Languages Integrate With?

Many types of software can integrate with open source markup languages. Content management systems, such as WordPress, Drupal, and Joomla all use markup languages to power their websites. Database management systems like MySQL and NoSQL also have integration capabilities with open source markup languages. Programming languages such as HTML, JavaScript, and CSS are used in conjunction with markup language to build dynamic web applications. Additionally, there are a variety of frameworks available that allow developers to create powerful web applications using the integration capabilities of open source markup languages such as Ruby on Rails or Node.js. Finally, many desktop publishing tools like Adobe InDesign or QuarkXPress offer integration options for these markups so users can make attractive layouts for print purposes.
