Lexical Analyzer Generator Quex download

The goal of this project is to provide a generator for lexical analyzers of maximum computational efficiency and maximum range of applications. This includes the support for Unicode (UTF8, UTF16, ...) and a large variety of other encodings directly and via nested converters such as ICU(tm) and IConv. Sophisticated buffer handling allows to operate on plain file streams, on sockets, or manually fed buffer content. 'Ready-to-build' examples explain related concepts and facilitate practical applications.

Features

Support for Unicode and many other character encodings.
Modes with inheritance relationships and transition rules.
Sophisticated buffer management.
Include stacks.
Customized token classes.
Template compression for code size reduction.
Path compression for code size reduction.
Possibility of indentation based lexical analysis, also called 'off-side rule' (INDENT, DEDENT, NODENT).
Produces direct coded lexical analyzers.
Adjustable implicit line and column number counting.
Introduces DFA Algebra.
Fuzzy-Matching/Edit Distance, Levenshtein and PseudoDamerau Automata.
Support for DNA analysis (\RNA and \DNA).

PRTG Catches Network Issues Before They Cause Downtime

Threshold-based alerts flag problems early, so your team can act before users notice, not after.

Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.
