When rewriting existing applications as well as when writing new programs,
it is useful to bear in mind important ECLiPSe features which can make
programs easier to write and/or faster:
- The maximum performance is obtained when calling nodbgcomp/0
at the beginning of the session, before compiling any program and loading
any libraries.
- ECLiPSe arrays and global variables (setval/2, getval/2) are usually
more suitable to store permanent data than assert/1 is, and are usually
faster.
- ECLiPSe has a number of language extensions which make programming
easier, see chapter 5.
- The predicates get_flag/2, get_flag/3,
get_file_info/3, get_stream_info/3, get_var_info/3
give a lot of useful information about the system and the data.
- The ECLiPSe macros often help to solve syntactic problems
(see chapter 12).
- The TkECLiPSe GUI provides many features that should make
developing programs easier than with the traditional tty interface.
- It is worth familiarising oneself with the debugger's features,
see chapter 14.
- ECLiPSe is highly customizable, even problems which seemingly
require modification of the ECLiPSe sources
can very often be solved at the Prolog level.
