When I was at Berkeley working on my dissertation, I
wrote a tool that would
let you edit a text file written in any language you could define with a
grammar, with syntax and semantic error checking while you edited. I had
grammars for several popular (in 1980) languages.
My curiosity is piqued. What were these languages?

My guess is Pascal and Lisp but that's just a guess. Oh, Fortran for sure.
Cobal maybe?

Well, the list is a fuzzy memory, but thanks to a great guy who read in
my magtapes, I was able to go back and UTSL.
Here is the list, minus the various copies and stubs. The definitions
were written in a notation I made up called Language Description
Language (LDL)
* ada.ldl (DOD language for embedded systems)
* asple.ldl (A Simple Programming Language Example, ACM Computing
Surveys 6/76. This was useful for getting the semantic checking
working.)
* c.ldl (no typedef or cpp)
* expr.ldl (a simple expression language)
* ldl.ldl (the Language Description Language itself)
* lisp.ldl
* pascal.ldl
* rigel.ldl (a database language from UCB)
* text.ldl (plain text)
One of these days in My Copious Free Time, I hope to get this beast
"BABEL" running again. It was painfully slow on a Vax, but it might be
OK on today's hardware.
