259.0. "Development Tools" by BECALM::NYLANDER () Thu Nov 30 1989 14:56

  A developer from across the ocean sent me the following two messages,
  requesting help in locating language development tools used within
  Digital engineering.

  I pointed him at TBL, LALRPAT, VCG, and GEM.  However, I'm sure that's
  not a definitive list of the generally useful tools that we use for
  language development.

  So, with Charles' permission I'm posting his note here.  Please reply
  and/or send Charles mail if you have compiler development technology
  which they may find useful.

	Thanks for the info, I'll follow up on the components you've mentioned,
        I think posting my request in the languages notes conference sounds
        like a good idea, might be worth adding that the output objects
        are EDI processable formats such as X12 , EDIFACT.

	thanks again Charles

	Hi:
		you were recommended by Andy Wilson, as someone who might
	be able to help me with the following item.

	( I by the way am Charles Fox, with the glorious title of Chief 
	  designer EDI engineering group, in Reading UK )

	In our next Corporate EDI product release, we want to build a component
	that we refer to as a Generic Translator...in fact it looks very
	much to me like a generic compiler, that takes as its input one of a 
        range of different structured information objects , based on a range of
        different (but simple) syntax.  

	The output being a new representation of said information object.

	I hope to avoid re-inventing the wheel here, and was wondering if
	you could point me in the direction of some info on what tools
	exist within DEC Engineering that I could utilze ?

	(e.g generic syntax analyzers , etc etc. ) 


	Thanks in advance for any pointers you care to give ,

	Charles Fox

    This sounds like an application for the Galileo parser
    generator, or for straight-forward coding in SCAN.  In
    either case, don't re-invent the wheel!
    
    SCAN has a conference at CLT::SCAN, according to 
    EASYNET_CONFERENCES.
    
    Galileo has a conference at GUESS::GALILEO.

    And, of course, for Ultrix users there are LEX, YACC, and AWK.  I
    believe these are also available under DECshell on VMS (instant
    portability).

    Who is the Keeper of LALR_PAT these days, anyway?
