LICENSE

This program is licensed under the terms of the GPL, a copy
of which you should have received with this package.


DEPENDENCIES

stacklib version>=1.2
binutils
some .h files that your system should have.

This package needs stacklib. The version of stacklib MUST be >=1.2. Version 1.2 added reverseStack() and won't compile if the version is less than that.


INSTALLATION:

Just use:
 make
to generate the binary if you don't have it already.

Maybe if you put it in a bin dir and add it to the $PATH, it's easyer to use.


USE:

./c-abacus
or
./c-abacus <num><op>...<num>
or even
./c-abacus "<num><op>...<num>"
if the string to calc has a '*' or a '/'. The OS doesn't care if it is a
calculator or not.

Obviously, <num> is a number and <op> is one of folowing operands:
(+ - * /)


KNOWN BUGS:

By now, there is the string correction no make yet. What is it?
Try 2.3.3 or making any word without much sence.
Any other problem found should be reported to us.


HISTORY:

Version 0.7b2
  All license issues resolved.

Version 0.7b (discontinued)
  Stacks being implemented. Some errors.

Former versions (discontinued)
  To see how c-abacus evolved, please see CHANGELOG.


FUTURE VERSIONS:

  Version 0.7
Stacks working well. Operation evaluation with no errors. Postfix operations implemented at full scale. Maybe parentesis.


TO DO:

To do there is A LOT of things to yet. Remember it's only the version 0.7.
With this decrescent priority list there is to do:

- Correct bugs if we find or someone reports some!  
- Prioriative operations.
- Parentesis.
- Unary (or even ternary) operands, like -1 or +1.
- automake/autoconf support.
- Don't allow strings with more than MAX_CANON characters.
- Last result on the console by a variable.
- Square root, exponentiation.
