The off-side rule describes syntax of a computer programming language that defines the bounds of a code block via indentation. [1] [2]The term was coined by Peter Landin, possibly as a pun on the offside law in association football.
Auto indentation: May refer to just simple indenting to the same level as the line above, or intelligent indenting that is language specific, e.g., ensuring a given indent style. Compiler integration : Allows running compilers/linkers/debuggers from within editor, capturing the compiler output and stepping through errors, automatically moving ...
Programmers often use tools to format programming language source code in a particular manner. Proper code formatting makes it easier to read and understand. Different programmers often prefer different styles of formatting, such as the use of code indentation and whitespace or positioning of braces.
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.
A plugin for Notepad++ named XML Tools is available. [4] It contains many features including manual/automatic validation using both DTDs and XSDs, XPath evaluation, auto-completion, pretty print, and text conversion in addition to being able to work on multiple files at once. Other tools are available to edit XHTML.
The rules a compiler applies to the source creates implicit standards. For example, Python code is much more consistently indented than, say Perl, because whitespace (indentation) is actually significant to the interpreter. Python does not use the brace syntax Perl uses to delimit functions. Changes in indentation serve as the delimiters.
Text formatting – Text editors often provide basic visual formatting features like line wrap, auto-indentation, bullet list formatting using ASCII characters, comment formatting, syntax highlighting and so on. These are typically only for display and do not insert formatting codes into the file itself.
Indentation style can assist a reader in various way including: identifying control flow and blocks of code. In some programming languages, indentation is used to delimit blocks of code and therefore is not matter of style. In languages that ignore whitespace, indentation can affect readability. For example, formatted in a commonly-used style:
