RegexBuddy
RegexBuddy helps users create, understand, test, debug, use, and save regular expressions.
What RegexBuddy is
RegexBuddy helps users create, understand, test, debug, use, and save regular expressions. Its builder assembles patterns from descriptive components and displays their structure in a tree. Users can test expressions against sample data or files, step through matches, and inspect the matching process. The software compares supported regex flavors and converts patterns between them, substituting equivalent syntax while noting behavioral differences. It can generate language-specific snippets for matching, extraction, search and replace, and splitting. A built-in GREP tool searches and replaces across files and folders. RegexBuddy supports 94 flavors, including PCRE, PCRE2, .NET, JavaScript, Java, Perl, PHP, Python, Ruby, Boost, RE2, ICU, and POSIX BRE/ERE. It is available for Windows; there is no native Linux version, though the Windows version can run on Linux using Wine with documented glitches and limitations. There is no free plan or evaluation version. The single-user license costs £44.95, paid once, excluding taxes. Licenses include email technical support and minor updates and bug fixes.
