Mempeek is a simple programming language designed to operate on the physical memory of a computer system

mempeek's Issues

subroutine context not cleared on error in definition

The subroutine context is not reset when a compile error occurs in a function or procedure definition. Mempeek crashes when the next function or procedure is defined.

log to file

What about having a start parameter (like -o) for logging an interactive session to file.

File operations

Storing and restoring data (content of variables for example) by file operations would be helpful.

compile errors leak memory

When a compile error occurs, the AST nodes created so far are not deleted

include guards

An error occurs when the same file is imported from several other imported files

add pragma command to set include search paths from mempeek code

copying of ranges in structures

On branch arrays:
when copying structures (def xxx 123 from yyy) the ranges of structure members (yyy.z{0}) are not copied

add config script executed on startup

commandline input abort

Use CTRL-C for abort current action, use CTRL-D for quitting mempeek.

retrieve mapping at compile time

peek and poke commands should retrieve the matching MMap object at compile time when address is constant

crash when accessing mapped memory

mempeek crashes when it is started in interactive mode and the user tries to acces interactively mapped memory after a loaded file has mapped memory.

Steps to reproduce:

• Create file test.mp with content map 0x10000000 0x1000
• Start mempeek with command mempeek test.mp -i
• Enter command map 0 10 "test.mp"
• Enter command print peek(0)

Implement drop function

Sometimes it would be useful to drop functions or variables out of scope. This would enable one to reload the function again, for example after a change in source.

naming conflict for subroutine parameters

An error is generated when a subroutine parameter has the same name as a defvar

Functions

The possibility of defining (and executing) functions would be nice.

autocomplete

Autocomplete for variables and functions/procedures

syntax error when entering empty line

A syntax error message is generated when an empty line is entered in interactive mode

map-statement accepting variables

Allow map-statement fed by variables or symbolic constants

example:
def address 0x1000000
map address 65535

Cursor positioning

The capability to control the output position would increase the clarity during cyclic output of many values.
