Now that distcheck no longer fails (see previous commit), let's address the shortcomings. * Makefile.am (CLEANDIRS, clean-local): New. * doc/local.mk, examples/calc++/local.mk, examples/local.mk, * examples/mfcalc/local.mk, examples/rpcalc/local.mk, * src/local.mk (CLEANDIRS): Get rid of Apple's *.dSYM directories. (CLEANFILES): Get rid of *.output files. * examples/variant-11.yy, examples/variant.yy: Don't generate any of the auxiliary files (location.hh and the like).
This directory contains calc++, a simple Bison grammar file in C++. Please, read the corresponding chapter in the documentation: "A Complete C++ Example". It is also available on line (maybe with a different version of Bison): https://www.gnu.org/software/bison/manual/html_node/A-Complete-C_002b_002b-Example.html To use it, copy this directory into some work directory, and run `make` to compile the executable, and try it. It is a simple calculator which accepts several variable definitions, one per line, and then a single expression to evaluate. The program calc++ expects the file to parse as argument; pass `-` to read the standard input (and then hit <Ctrl-d>, control-d, to end your input). $ ./calc++ - one := 1 two := 2 three := 3 (one + two * three) * two * three <Ctrl-d> 42 You may pass `-p` to activate the parser debug traces, and `-s` to activate the scanner's. ----- Local Variables: mode: outline fill-column: 76 End: Copyright (C) 2018 Free Software Foundation, Inc.
