I am fooling around with creating a Windows based IDE for DuckyScript.

So far I have very basic syntax highlighting and very basic compilation. Is there any interest in an application like this?

I do have a question for Jason Appelbaum though, how are the DELAY commands parsed? I am not too familiar with java, but it looks like the encoder class just says Byte.parseByte("500") or Byte.parseByte("1700") which would exceed a byte's capacity of 127. Does parseByte just return 127? Or am I missing something?

Another question for Jason though, my encodings are coming out a bit different. For the ESCAPE command, the code looks like it gets a byte for decimal 41 and for decimal 0. Which I would think output hex29, hex00. But it looks like it comes out as hex08 hex01. How should the ESCAPE command come out in hex? I must be missing something obvious.

I don't know the exact hex codes as I'm still on my cell coming home from Derbycon but let's use this as a test case for troubleshooting. What I'd like from you are the following:

What text editor are you using? Can you attach both the txt and bin?

Alternatively,

Could you create a text file containing only "ESCAPE" (without quotes), duckencode it and provide the hexedit output of the resulting bin. For example:

echo ESC >> esc.txt

java -jar duckencode.jar -i esc.txt -o esc.bin

hexedit esc.bin

Thanks!

Here is a zip with six files. One with only escape (08), one with escape, control escape (29, 01) and one with the previous and some more (08, 01, ...). I would think they all would start with the same hex values, but the one with some more starts differently. I need to find out more about java's default encoding format. I am using Windows 7 notepad.

When I run your escape.txt against my duckencode.jar I get the same hex output: 08 01

cat'ing escape.txt reveals two lines:

ESCAPE

CONTROL ESCAPE

When I create my own escape2.txt with the above two lines and compile it with the same duckencode.jar I get this hex output:

29 00 29 01

The "29 00" is line 1 -- ESCAPE while "29 01" is line 2 -- CONTROL ESCAPE. To break it down further, "29" is ESCAPE, "00" is null and "01" is CONTROL.

I've tested and come up with the same results while working in nano, vi and gedit.

So then I checked the hex results of both your escape.txt and my escape2.txt and here's what I've found

Yours:

00000000 45 53 43 41 50 45 0D 0A 43 4F 4E 54 52 4F 4C 20 45 53 43 41 ESCAPE..CONTROL ESCA

00000014 50 45 0D 0A PE..

Mine:

00000000 45 53 43 41 50 45 0A 43 4F 4E 54 52 4F 4C 20 45 53 43 41 50 ESCAPE.CONTROL ESCAP

00000014 45 0A 0A E..

The carriage return "0A" is in common on both, but your editor seems to be adding "0D" before the return.

May I ask, what text editor are you using and what format options do you have when saving?

Will add this to the list of features to implement in the next version of the duckencoder -- ignoring the "0D" value.

+1 for IDE - would love to see the iducke function/writeline functionality w/o being connected to the Internet.
