vi (pronounced as distinct letters, / ˌ v iː ˈ aɪ / ⓘ) [1] is a screen-oriented text editor originally created for the Unix operating system.

A range is two line numbers separated by a comma ($ means the last line). In return, ed lists all lines, from first to last. These lines are ended with dollar signs, so that white space at the end of lines is clearly visible.

For each line, it prints the line number (on a 6 character-wide field) and then the line contents. For example, when executed on this input: Rome Florence Milan Naples Turin Venice
Leo can manipulate text or code in any human or computer programming language (e.g., Python, C, C++, Java), as Leo is a language-independent or "adaptable LPE" (literate programming environment). [1] Syntax highlighting is provided for many different programming languages. [2] Leo is written in Python and can be extended with plugins written in ...
