Support for code comments is defined by each programming language. The features differ by language, but there are several common attributes that apply throughout. Most languages support multi-line block (a.k.a. stream) and/or single line comments. A block comment is delimited with text that marks the start and end of comment text. It can span ...
In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
Visual Studio Code was first announced on April 29, 2015 by Microsoft at the 2015 Build conference. A preview build was released shortly thereafter. [13]On November 18, 2015, the project "Visual Studio Code — Open Source" (also known as "Code — OSS"), on which Visual Studio Code is based, was released under the open-source MIT License and made available on GitHub.
Comments are a form of human-readable metadata, and lengthy comments can disrupt the flow of code. This can be the case either for a long comment for a short section of code, such as a paragraph to explain one line, or comments for documentation generators, such as Javadoc or XML Documentation. Code folding allows one to have long comments, but ...
Comment programming, also known as comment-driven development (CDD), is a (mostly) satirical software development technique that is heavily based on commenting out code. [1] In comment programming, the comment tags are not used to describe what a certain piece of code is doing, but rather to stop some parts of the code from being executed. The ...
Line vs. block – a line comment starts with a delimiter and continues to the end of the line (newline marker) whereas a block comment starts with one delimiter and ends with another and can cross lines; Nestable – whether a block comment can be inside another block comment
Haskell encourages the use of literate programming, where extended text explains the genesis of the code. In literate Haskell scripts (named with the lhs extension), everything is a comment except blocks marked as code. The program can be written in LaTeX, in such case the code environment marks what is code. Also, each active code paragraph ...
A simple custom block in the Snap! visual programming language, which is based on Scratch, calculating the sum of all numbers with values between a and b. In computing, a visual programming language (visual programming system, VPL, or, VPS), also known as diagrammatic programming, [1] [2] graphical programming or block coding, is a programming language that lets users create programs by ...
