UBDebug - An Interactive Development Environment for CHDK uBasic Scripts
UBDebug is a PC-based IDE for CHDK ubasic scripts that runs under Windows, Mac OSX (10.3 "Panther" or later) and Ubuntu Linux (perhaps other flavours too). It lets you create and edit scripts, then step through them line by line while inspecting and setting variables. You can also set the values to be returned by some CHDK functions (such as get_usb_power) and any property. Here's what it looks like when it's running (under OSX 10.5):
The following files can be downloaded:
- the debugger zip file (universal version)
- a short PDF document describing how to user the debugger
- an OSX App in disk image form
| UBDB.jar | this contains the five java classes which make up the debugger |
| ubengine.dll | the native methods and ubasic interpreter (Windows version) |
| runubdb.bat | a bat file to run the debugger under Windows (double-click to run) |
| libubengine.jnilib | the native methods and ubasic interpreter (Mac OSX version - supports both PowerPC and Intel Macs) |
| ubengine.so | the native methods and ubasic interpreter (Ubuntu Linux version) |
| runubdb.sh | a bash script to run the debugger under Linux (double-click to run) |
| test.bas | a simple test script |
Unzip the files into any convenient directory. To run the debugger simply double-click the .jar file.
Usage Notes
- only uBasic scripts are supported (not Lua)
- scripts can be edited only when not running (i.e. before Start is pressed or after Stop is pressed)
- a breakpoint (only one) can be set by double-clicking on a line. If Run is then pressed, the script executes until the breakpoint is reached (or the script ends)
Last update - January 2012 - add Ubuntu Linux version.
Experimental String Version Available
An extended version of UBDebug which supports strings as well as integers is available here
SDM Version Available
A version which supports SDM is available here

Note
The uBasic interpreter that forms part of CHDK, and is wrapped up in the DLL, was written by Adam Dunkels, to whom many thanks.
