| 2 * | |
| 151 | 3 * MzScheme interface by Sergey Khorev <sergey.khorev@gmail.com> |
| 4074 | 4 * Based on work by Brent Fulgham <bfulgham@debian.org> |
| 14 | 5 * (Based on lots of help from Matthew Flatt) |
| 6 * | |
| 7 * This consists of six parts: | |
| 8 * 1. MzScheme interpreter main program | |
| 9 * 2. Routines that handle the external interface between MzScheme and | |
| 10 * Vim. | |
| 11 * 3. MzScheme input/output handlers: writes output via [e]msg(). | |
| 12 * 4. Implementation of the Vim Features for MzScheme | |
| 13 * 5. Vim Window-related Manipulation Functions. | |
| 14 * 6. Vim Buffer-related Manipulation Functions | |
| 15 * | |
| 16 * NOTES | |
| 17 * 1. Memory, allocated with scheme_malloc*, need not to be freed explicitly, | |
| 18 * garbage collector will do it self | |
| 19 * 2. Requires at least NORMAL features. I can't imagine why one may want | |
| 20 * to build with SMALL or TINY features but with MzScheme interface. | |
| 1894 | 21 * 3. I don't use K&R-style functions. Anyways, MzScheme headers are ANSI. |
