This directory contains source for a version of yacc needed by the Pascal
|
|
parser. The differences between this yacc and a stadard version 6 yacc
|
|
are indicated in a comment in y1.c.
|
|
|
|
Note that the standard yacc parser will not work on the tables produced
|
|
by "eyacc" and also that these changes are really useful only with
|
|
a fairly large set of error recovery routines which are part of both
|
|
"pi" and "pxp". The routines are language independent, but the method
|
|
will only work on languages which have some redundancy in them... it is
|
|
probably ill suited for C, but would work fine in ALGOL-60, ALGOL-W,
|
|
EUCLID, LIS, SP/K, PL/1, ALPHARD, CLU, ...

A paper describing the method used by eyacc will appear in August in the
|
|
SIGPLAN Boulder conference.

The eyacc in this directory has been modified to work for
|
|
version 7. This involved syntax fixes and changing the I/O calls
|
|
to standard version 7 calls.
