Sre—a syntax recognizing editor

Abstract

Abstract This paper presents a syntax‐directed editor dubbed SRE, for syntax recognizing editor. Unlike other syntax‐directed editors, SRE enables the user to edit programs with nearly the same natural and unrestrictive ease as a conventional text editor. In addition, it helps identify syntax errors and many typing errors before leaving the editor and attempting to compile a program. Programs are also formatted during entry, thereby providing immediate visual feedback of the recognized structure. The editor replaces the scanner/parser pass of a conventional compiler and thus reduces compilation time substantially.
