The Sass interpreter translates SassScript into CSS. Alternatively, Sass can monitor the .sass or .scss file and translate it to an output .css file whenever the .sass or .scss file is saved. [5] The indented syntax is a metalanguage. SCSS is a nested metalanguage and a superset of CSS, as valid CSS is valid SCSS with the same semantics ...
PostCSS is a framework to develop CSS tools. [ 5 ] It can be used to develop a template language such as Sass and LESS. [ 6 ] The PostCSS core consists of: [ 7 ] CSS parser that generates an abstract syntax tree. Set of classes that comprises the tree. CSS generator that generates a CSS line for the object tree.
Abstract syntax tree. An abstract syntax tree (AST) is a data structure used in computer science to represent the structure of a program or code snippet. It is a tree representation of the abstract syntactic structure of text (often source code) written in a formal language. Each node of the tree denotes a construct occurring in the text.
In computing, a here document (here-document, here-text, heredoc, hereis, here-string or here-script) is a file literal or input stream literal: it is a section of a source code file that is treated as if it were a separate file.
Python is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of their features support functional programming and aspect-oriented programming (including metaprogramming [73] and metaobjects). [74] Many other paradigms are supported via extensions, including design by ...
Mixin programming is a style of software development, in which units of functionality are created in a class and then mixed in with other classes. [6] A mixin class acts as the parent class, containing the desired functionality. A subclass can then inherit or simply reuse this functionality, but not as a means of specialization.
The enclosed text becomes a string literal, which Python usually ignores (except when it is the first statement in the body of a module, class or function; see docstring). Elixir. The above trick used in Python also works in Elixir, but the compiler will throw a warning if it spots this.
Hard coding. Hard coding (also hard-coding or hardcoding) is the software development practice of embedding data directly into the source code of a program or other executable object, as opposed to obtaining the data from external sources or generating it at runtime. Hard-coded data typically can only be modified by editing the source code and ...
