Iosevka is an open-source sans & slab-serif monospace quasi-proportional typeface utility designed to write code using terminals and to prepare technical documents. It supports multiple languages and contains various stylistic sets to change the shape of certain characters. It can be configured to cherry-pick variants for each character using OpenType.
In the official package, the utility provides six monospace subfamilies, including the sans-serif, slab-serif, each in the three spacing’s default, Term, and fixed with two quasi-proportional Aile and Etoile. In all monospace, there are nine weights (Thin to heavy), two widths (normal to extended), and three slopes (Upright, Italic, and Oblique).
Noto Mono is a software utility that provides free and beautiful fonts for your desktop for all languages. The font family consists of hundreds of individual fonts, and all the scripts are entirely encoded in the Unicode standard. The software is particularly useful when text is seemed to be rendered by a computer, and sometimes the characters in the text cannot be displayed.
The software is developed under Google and providing support for all the languages with a harmonious look and feel. Noto Mon has different styles and weights and can be used freely for everyone. You can get the comprehensive set for fonts and tools for development purposes from the GitHub repositories. Furthermore, Noto Mono richly collaborates with the type of designers globally to create a directory of open-source fonts and is easily accessible to anyone for any project.
Google Noto Fonts is a font family covering all the scripts encoded in the Unicode standard that aims to support all languages with a harmonious look and feel with sans-serif classification. The Noto family is developed with the goal of achieving visual harmony with heights and stroke thicknesses across multiple languages/scripts. When text is rendered by a computer, sometimes that text will contain a character that cannot be displayed because no font that contains it is installed on the computer.
When this happens, a substitute character, typically a small rectangle, is shown to represent it. In slang, those small rectangles have sometimes been called “tofu” because of their visual similarity to that product. The Noto Emoji project provides color and black-and-white emoji fonts, including Gmail, Google Chat, Google Meet, Hangouts, YouTube apps, Android, and Chrome operating systems. Some projects provide a package for installing Noto fonts, e.g., Debian, Arch Linux, Gentoo Linux, CTAN.
PragmataPro is a monospaced font utility designed for programming with font’s implementation of Unicode characters, polytonic, Cyrillic, Arabic, Hebrew, and the APL code points, created by Fabrizio Schiavi. It is a narrow programming font developed for legibility, and the characters are hinted at by hand. The font specifically implements ligatures for coding, such as multiple character operators.
PragmataPro is programmed to have contained line-spacing and offer rasterization for screens of most sizes except the smallest. It has no interline spacing, so the lines are more compact in height, not just in width, and can be viewed in a lot of windows at the same time by the user. More than 9,000 characters have been optimized from 9pt to 48pt to guarantee the best readability. Moreover, its notable features include math and phonetics support with the Sans-serif classification specialty.
Hasklig is a monospaced programming tool used to deal with symbols and characters in the coding font for ligatures with rendering multi glyphs. Academic articles featuring Haskell code often use Ihs2tex to achieve an appealing rendering, but it is of no use when programming. Some Haskellers have resorted to Unicode symbols, which are valid in the ghc, often with one-character-wide and eye-strainingly mode. Additionally, it displays as substitutes to underlying multi-character representation as vim2hs and characters go out of alignment.
Hasklig solves the problem the way typographers have always solved ill-fitting fonts, which often occur ligatures and underlying code stays the same with representation changes. Not only can multi-symbol glyphs be rendered more vividly, other problematic things in monospaced fonts, such as spacing, can be corrected. Building font instances repository includes so-called master weights with effectively extra light and black coloring. The platform supports 33 ligatures and gives code editors with better access. Moreover, it offers really precise control over which symbols’ designs customers want to use with OpenType.
Dank Mono is the delightful typeface ligature and an italic variant coding that provides custom coding font with monospaced efficacy. The included character set includes Latin uppercase and lowercase letters, all modifiers, and diacritics covering most European languages. Additionally, it covers an exhaustive list of math symbols, the basic Greek glyphs, and some terminal glyphs like Unicode block symbols, shades, circles, arrows, and Powerline symbols.
The utility includes twenty-six different code character combinations used by thousands of developers. Dank Mono is about details and aesthetics and doesn’t compromise to optimize rendering at small font sizes. Some features of the tool are invisible at smaller sizes or would contribute jaggedness at sizes below 10px. These are specifically for presentational purposes but are indeed visible on high-resolution displays even at 14px sizes in a subtle way.
Monoid is a mathematical solution set that is closed under an associative binary operation and has an identity element, known as commutative monoid as well. In math, the associative property is a property of some binary operations, which means that rearranging the parenthesis in an expression will not change the result. They are semigroups with identity; such algebraic structures occur in several branches of math—for example, the function from a set into itself from a monoid with respect to function composition.
In computer science and programming, the set of strings built from a given set of characters is a free monoid. Transition monoids and syntactic monoids are used in describing finite-state machines, and Trace and History Monoids provide a foundation for process calculi and concurrent computing. In theoretical computer science, the study of monoids is fundamental for automata theory.
