My feeling is in accordance with those who think that scripting languages have a very different philosphy than Ada - like type safety issues, weaker emphesize (to say the least!) on readablity etc. So I wouldn't go in the direction of an Ada or Ada-like scripiting language, but rather in one or both of these directions: - packages that supply functionality useflu for scripting jobs. - embeddable little languages that can be used from inside Ada systems. Some idea of what I mean (but in a different context and hence not developed in full) can be found in my work on frameworks (URL below). 1. An Awk-alike frameowrk which allow Awk style processing to be done easily inside Ada systems (including the parsing to fields, records, implicit conversions etc. - but all done as subroutine invocation in Ada) 2. SEPI - the Simple Embeddable Parser and Interpeter (far from being ready for daylight...) which should allow you to put an interperter for a simple lagnuage inside you code. This topic is quite interesting, but since i don't have the time right now to write it up, I suggest those interested in some of my ideas on this look at: http://purl.oclc.org/NET/ehud-site/ada/frameworks.html Ehud Lamm mslamm@mscc.huji.ac.il http://purl.oclc.org/NET/ehudlamm <== My home on the web Check it out and subscribe to the E-List- for interesting essays and more!
