There + is now a working, if trivial, example. + + Tidiness: the code was compiled with as many gcc warnings enabled as + I could find. Very few problems turned up. Some unused function + arguments were removed. Where unused arguments could not be removed + (because the function is one of a set that must all have the same + prototype), they were renamed to `ignore'. + + Portability: some versions of readline define the name `Function', + which rc also uses. Its use in rc has been renamed to `rc_Function'. + + Documentation: the `history' man page didn't explain what end of line + does in editing mode. It now does. + + Bug: the interaction with readline was broken, particularly with + respect to signal handling. I've incorporated some changes from Tom + Culliton which should sort this out. Unfortunately, we now have 3 different + code paths for readline 2.1, readline 2.2, and editline :-(. + + Configuration: if you say `--with-readline' or `--with-editline' it is now an + error if the appropriate library is not found. |
