|
|
|
2 *
|
|
|
3 * MzScheme interface by Sergey Khorev <khorev@softlab.ru>
|
|
|
4 * Original work by Brent Fulgham <bfulgham@debian.org>
|
|
|
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.
|
|
|
21 * 3. I don't use K&R-style functions. Anyway, MzScheme headers are ANSI.
