Hover Hugs

Hover Hugs is a heavily striped down version of Hugs98. It's an attempt to make the codebase more palpable.

Changes

• Removal of all platforms except Linux
• Removal of all packages except hugsbase
• Complete rewrite of the build system to use standard make
• The Hugs path is now relative to the executable

Internal Changes

• Unicode table is now generated at build time
• ffihugs is now a wrapper over runhugs
• Header files have been made properly independent
• Including source files no longer include other source files (TODO: parser.c)
• Delete lots of unneed #if branches (TODO: still incomplete)
• Convert #define into proper c constructors (BIG TODO: very incomplete)
• Various other clean ups

Status

Hover Hugs is still not is a good shape. There's still lots of unneeded preprocessor conditionals, awful macro usage, and K&R definitions. A lot of comments are outdated too, now that a lot of platform support has been removed.

Some modules in hugsbase don't work because they depend on base modules. Eventually, those modules need to be removed or the original base definitions need to supplied somehow. At least the Prelude seems to work.

Everything under demos/, tests/, lib/, docs/ and some other files ace complete untested and may be scrapped.

Long term, it would be nice if Hugs could be gradually ported to a C compatible language that has garbage collection. Something like D or Go.

Building

Edit src/config.h manually to change the build configuration. As mentioned before Linux is currently the only supported platform.

Running make should build a dist folder which contains the bin for the associated executables. These executable are portable so they can be moved anyware.
