CORE LANGUAGE FEATURES
- Traces
- Closures, exported as a command that can set/get/unset elements
from a dictionary associated with the current procedure.
The [closure] command should allow to perform this operations,
and to access the closure of a procedure from another one.
CORE COMMANDS
- All the missing standard core commands not related to I/O, namespaces, ...
- [tail] command for programmer-driven tail recursion optimization
- The current [expr] needs a lot of work, expecially operators && and ||
are not lazy. Math functions are not present but probably will never
be added as expr functions, but as Tcl commands, like [sin], [cos] and
so on.
COMMANDS NOT IN TCL BUT THAT SHOULD BE IN JIM
- commands to operate on sets (that are lists semantically).
EXTENSIONS
- Regexp extension
- OOP system (this will possibly part of the core)
SPEED OPTIMIZATIONS
- Cache call frames instead to free/realloc they at every proc call.
IMPLEMENTATION ISSUES
- Objects lazy free.
- [split $string {}] should generate a list with Jim_Obj of chars shared.
- [closure] command to set/get procedures-specific closure variables.
For example:
- Remove SetTypeFromAny() method from the Jim_ObjType structure.
It's not useful, and it may be useful to have different prototypes
for the Set*FromAny() procedures of different types.
ERROR MESSAGES
- Display the procedure relative file number where the error happened.
Like:
In procedure 'check' line 11, called at file "test.tcl", line 1024
instead of just:
In procedure 'check' called at file "test.tcl", line 1024
REFERENCES SYSTEM
- The format of the reference will be changed form ~reference:000............:
to <reference-<typename>-000000000......>, where typename is the name
of the type supplied to the [ref] command at reference creation time.
This name is only informative but is stored inside the reference
structure, so that for example [lambda] will have as reference name
something like <reference-<function>-00000000000000001>, and
a list node <reference-<listnode>-00000000000000002> and so on.
This makes debugging easier. The name is totally ignored by the
garbage collection stage.
