CORE LANGUAGE FEATURES
CORE COMMANDS
- All the missing standard core commands not related to I/O, namespaces, ...
- More math functions in expr?
- [onleave] command, executing something as soon as the current procedure
returns. With no arguments it returns the script set, with one appends
the onleave script. There should be a way to reset.
OTHER COMMANDS NOT IN TCL BUT THAT SHOULD BE IN JIM
- Set commands: [lunion], [lintersect], and [ldifference]
EXTENSIONS
- OOP system
- Cryptography: hash functions, block ciphers, strim ciphers, PRNGs.
- Tuplespace extension (http://wiki.tcl.tk/3947) (using sqlite as backend)
- Zlib
- Gdlib
- CGI (interface compatible with ncgi, but possibly written in C for speed)
SPEED OPTIMIZATIONS
- Find a way to avoid interpolation/reparsing in "foo($bar)" tokens.
See the "sieve" and "ary" bench performances, result of this problem.
(to compare with sieve_dict is also useful.)
- Experiment with better ways to do literal sharing.
- Organize the 'script' object so that a single data structure is
used for a full command, and interpolation is done using an
'interpolation token type' like JIM_TT_VAR and so on.
This way there is no need to run the array of integer objects
with the command structure. Also should help for better cache usage.
- Generate .c from Jim programs, as calls to the Jim API to avoid
the performance penality of Jim_EvalObj() overhead. In the future
try to generate the calls like a JIT emitting assembler from
Jim directly.
IMPLEMENTATION ISSUES
- Objects lazy free.
- Rewrite all the commands accepting a set of options to use Jim_GetEnum().
- Every time an extension is loaded Jim should put the dlopen() (or win32
equivalent) handle in a list inside the interpreter structure. When
the interpreter is freed all this handles should be closed with dlclose().
- *AssocData() function should allow to specify a delProc C function like
in the Tcl API. When the interpreter is destroied all the delProc functions
should be called to free the memory before to free the interpreter.
- Convert dicts from lists directly without to pass from the string repr.
REFERENCES SYSTEM
- Unify ref/getref/setref/collect/finalize under an unique [ref] command.
- Add a 'call' attribute to references in order to call a given procedure
if the name of a reference is used as command name.
RANDOM THINGS TO DO ASAP
- .jimrc loading, using the ENV variable
