Changes are mostly to the dir structures and build system for ScriptFu. Some changes to the outer plugin source to call the library. Why: so that other executables (future gimp-scheme-interpreter, or a future separated script-fu-server) can exist in separate directories, and share the library in memory (when built shared.) Whether the library is built shared and installed on its own (versus static and not installed) is a compile time option (both automake LibTool and meson abstract it away) The default is shared and installed, say as libgimp-scriptfu-3.0.so. Installed alongside other shared libraries (e.g. wherever libgimp is installed) to simplify packaging. A preliminary refactoring which helps enable MR gimp!647

Building TinyScheme
|
|
-------------------
|
|
|
|
The included makefile includes logic for Linux, Solaris and Win32, and can
|
|
readily serve as an example for other OSes, especially Unixes. There are
|
|
a lot of compile-time flags in TinyScheme (preprocessor defines) that can trim
|
|
unwanted features. See next section. 'make all' and 'make clean' function as
|
|
expected.
|
|
|
|
Autoconfing TinyScheme was once proposed, but the distribution would not be
|
|
so small anymore. There are few platform dependencies in TinyScheme, and in
|
|
general compiles out of the box.
|
|
|
|
Customizing
|
|
-----------
|
|
|
|
The following symbols are defined to default values in scheme.h.
|
|
Use the -D flag of cc to set to either 1 or 0.
|
|
|
|
STANDALONE
|
|
Define this to produce a standalone interpreter.
|
|
|
|
USE_MATH
|
|
Includes math routines.
|
|
|
|
USE_CHAR_CLASSIFIERS
|
|
Includes character classifier procedures.
|
|
|
|
USE_ASCII_NAMES
|
|
Enable extended character notation based on ASCII names.
|
|
|
|
USE_STRING_PORTS
|
|
Enables string ports.
|
|
|
|
USE_ERROR_HOOK
|
|
To force system errors through user-defined error handling.
|
|
(see "Error handling")
|
|
|
|
USE_TRACING
|
|
To enable use of TRACING.
|
|
|
|
USE_COLON_HOOK
|
|
Enable use of qualified identifiers. (see "Colon Qualifiers - Packages")
|
|
Defining this as 0 has the rather drastic consequence that any code using
|
|
packages will stop working, and will have to be modified. It should only
|
|
be used if you *absolutely* need to use '::' in identifiers.
|
|
|
|
USE_STRCASECMP
|
|
Defines stricmp as strcasecmp, for Unix.
|
|
|
|
STDIO_ADDS_CR
|
|
Informs TinyScheme that stdio translates "\n" to "\r\n". For DOS/Windows.
|
|
|
|
USE_DL
|
|
Enables dynamically loaded routines. If you define this symbol, you
|
|
should also include dynload.c in your compile.
|
|
|
|
USE_PLIST
|
|
Enables property lists (not Standard Scheme stuff). Off by default.
|
|
|
|
USE_NO_FEATURES
|
|
Shortcut to disable USE_MATH, USE_CHAR_CLASSIFIERS, USE_ASCII_NAMES,
|
|
USE_STRING_PORTS, USE_ERROR_HOOK, USE_TRACING, USE_COLON_HOOK,
|
|
USE_DL.
|
|
|
|
USE_SCHEME_STACK
|
|
Enables 'cons' stack (the alternative is a faster calling scheme, which
|
|
breaks continuations). Undefine it if you don't care about strict compatibility
|
|
but you do care about faster execution.
|
|

OS-X tip
|
|
--------
|
|
I don't have access to OS-X, but Brian Maher submitted the following tip:
|
|
|
|
[1] Download and install fink (I installed fink in
|
|
/usr/local/fink)
|
|
[2] Install the 'dlcompat' package using fink as such:
|
|
> fink install dlcompat
|
|
[3] Make the following changes to the
|
|
tinyscheme-1.32.tar.gz
|
|
|
|
diff -r tinyscheme-1.32/dynload.c
|
|
tinyscheme-1.32-new/dynload.c
