Guile , an acronym for GNU Ubiquitous Intelligent Language for Extensions , is the official extension language for the GNU operating system and is being developed as part of the GNU project . Guile is an interpreter for the Scheme programming language , a Lisp dialect. The compiler infrastructure, libraries, and dynamic programming environment make Guile a powerful language for writing applications. Guile is implemented as a program library that can be incorporated into other programs to promote their expandability. Not all GNU projects support Guile yet; GIMP's scripting engine, for example, relies on the "competition" TinyScheme .

In the future, Guile will also support other scripting languages ​​such as Perl and PHP . However, it currently supports CTAX, a C-like language. One of the future goals of Guile is to be able to “translate” from any other language according to Scheme and to be able to generate portable bytecode from this ; Guile would then be a language-neutral runtime environment.

Guile supports XML , XPath , and XSLT , the forms of SXML , SXPath, and SXSLT . The S-expression -based XML processing is also supported.

history

The origins of Guile lie in a discussion started by Richard Stallman and later known as "the Tcl wars ": Stallman claimed that Tcl was not powerful enough to serve as an extension language. It was for this reason that he started the Guile Project. At that time the Scheme definition existed, but there was still no interpreter. Thus, with Guile, the first somewhat standard-compliant interpreter was created. Mention should be made of Tom Lord , one of the main programmers who was then employed at Cygnus Solutions (later Red Hat ).

The first versions were split off from SIOD (“Scheme in One Defun”) and the SCM interpreter before 1995 .

Properties of the Guile interpreter

The Guile interpreter adds the following capabilities to Scheme:

Unlike Scheme itself, Guile is case sensitive
