Licensing explained

The standard license for RegExpr is the single license. A single license could be described as "developer license". It includes the full source code and the license for one developer to use it in any number of programs and on any number of installations.

Each developer that uses RegExpr needs a separate license. You may include RegExpr in your projects even if more developers work on them, provided that you have one license for each developer that writes calls to RegExpr.

You can distribute RegExpr in any number of programs, provided that they are compiled in binary executable form. If you need to distribute the source code as part of a larger program, please see the full license terms.

Full license terms


All licenses include all future versions of RegExpr. No new versions are planned to be released, though.

Version history


The software is provided 'as is'. No claims about the correctness of RegExpr are made, although the sincere objective of RegExpr is to provide features similar to regular expressions in Perl. The intention of the author is to try to remove all bugs if such creatures should appear in the RegExpr code.
