is there a master list of commands for script writers?

Hello, I've been messing around with CDHK for about a week now, and I really enjoy this software and all the scripts people have been contributing.

I would like to write a few scripts of my own, but I am a little lost.  I am familiar with BASIC (basic stamp and picaxe microcontrollers)  but there are a lot of CDHK specific commands that come up, and I have no idea how to use them.

Is there a master list of all the commands that can be used in these scripts, what cameras those commands are compatible with, how long a script can be, how many variables can I use? etc.

some of the commands are fairly obvious, like:  @title, @default, @param,  md_detect_motion, set_raw_nr,  set_raw,  set_iso,  set_tv96_direct,  shoot, etc.

but it would be really helpful to have a list of all the variables available in the standard CDHK build.
I have been looking around on this forum for the past few days, and haven't been able to find anything.

Hi headless_rabbit,

you'll find the needed informations for uBasic in the CHDK wikia:
  http://chdk.wikia.com/wiki/UBASIC/TutorialScratchpad
  http://chdk.wikia.com/wiki/UBASIC/uBASIC_syntax

Besides uBasic there's another, more powerful scripting language available in CHDK: Lua
  http://chdk.wikia.com/wiki/LUA
  http://chdk.wikia.com/wiki/LUA/LUA_syntax
  http://chdk.wikia.com/wiki/LUA/LUA_Reference
 
Also have a look (for both, uBasic and Lua) to the list of new scripting commands:

Of course, the most accurate list is found in the source ;)

Speaking of which, is there a single point of access + directions for downloading source and compiling it?  I prefer linux environment, slackware, if it matters, 'cos I haven't done windoze app development for a decade.

Also, is there an emulator for running scripts?  Or is that idea totally silly due to the range of supported cameras all being the same only different?

Note that rolling your own tool chain has some quirk, be sure you read the relevant pages/threads.

I started a lua based script emulator, mentioned in this thread http://chdk.setepontos.com/index.php/topic,2929.0.html but haven't had time to work on it recently. Just having a syntax check with the CHDK functions dummied on the PC helps a lot.

The SDM ubasic debugger (http://www.zenoshrdlu.com/kapstuff/zsdmubdb.html) and CHDK ubasic debugger (http://www.zenoshrdlu.com/kapstuff/zubdb.html) are reasonably up-to-date in terms of supported ubasic functions.

SDM has many, powerful uBasic commands that are not in the basic version of CHDK.

See descriptions here.

there are also lots of chdk-ubasic commands that are not in sdm. oh, and lets not forget lua.

I'm just getting into Lua, and I've noticed some common uBasic commands don't seem to work.

ex. uBasic: set_iso 3
Lua: tried set_iso(3), but my camera's saying that's not available.  Other setting changes appear to also be unavailable in lua, unless there's something I'm not doing correctly (forgetting to include a lib?)

set_iso_mode is does the same thing, in both ubasic and lua.
