Minotaur for Perl, Python, and Tcl.
Initial implementation involves Perl, Python , and Tcl , but basic bindings have been set up for Java , Lua , PHP , and potentially any language that is designed to be able to be embedded inside something else.
Minotaur is based on pForth, and embeds one scripting language, "inside" the other at runtime, using Forth as the "superglue" that implements callbacks to get back into the other language interpreter at runtime.
SLANG tends to be imbedded into applications; I'm not aware of there being a "SLANG Shell." Notable applications that embed SLANG include the slrn news reader, a text editor called JED, a spreadsheet package originally based on SC, a version of the Lynx web browser, the Mutt mail client, and the DOS emulator DOSEMU.
These are responsible for most of the inspiration of the scripting languages described here...
Turns Unix Shell scripts into a compiled form (using C) such that the internal contents are not revealed. Running strings won't tell you what it does...
It can be used for pretty much any shell that supports the
-c option to load commands from a string.
Small is a simple, typeless, 32-bit extension language with a C-like syntax. A Small "source" program is compiled to a binary file for optimal execution speed. The Small compiler outputs P-code (or bytecode) that subsequently runs on an abstract machine. Execution speed, stability, simplicity and a small footprint were essential design criteria for both the language and the abstract machine.
A shell programming language implemented in Ada that provides Ada syntax. Text scripts may, if desired, be compiled into object code using an Ada 95 compiler.
