Regular expressions are a fundamental technique for pattern matching in textual data and for lexical analysis in compiler design. They are ubiquitous in most systems used today, including operating...doi:10.1007/978-3-319-91274-5_7Torgersen, Todd C....
In this work, we explore how regular expressions evolve over time, focusing on the characteristics of regular expression edits, the syntactic and semantic difference of the edits, and the feature changes of edits. Our exploration uses two datasets. First, we look at GitHub projects that have a...
This consideration leads to the application of modern compiler and translator writing system technology to the design and implementation of general macro processors. REGULUS is a general purpose macro processor based on regular expressions and is designed following the above mentioned considerations. ...
Automatic visualization makes compiler design/construction coursework much less tedious. Underlying Theory The Thompson-McNaughton-Yamada construction (aka Thompson construction) algorithm converts regular expressions into graphs. This is the algorithm underlying creation of the NFA. The subset/powerset constr...
Regular expressions compiled to a special-purpose assembly can be used only in instance method calls. Regular expressions that are compiled to assemblies move much of a regular expression’s startup cost from runtime to design time. In a run-time enviro...
compiler can execute them. Interpreted regular expressions reduce startup time at the cost of slower execution time. Because of this process, they're best used when the regular expression is used in a small number of method calls, or if the exact number of calls to regular expression methods...
