[Suggestion] Possible Duck Dev Improvement

[overwraith]

I have found that often one wants to write an ASCII file, like a batch file, or something, and then wants to convert the file to Duck Script which involves;

batch.bat~

Bat cmd

Bat cmd

Bat cmd

Bat cmd

Duck Script~

REM INPUT FILE BATCH.BAT

STRING copy con batch.bat

ENTER

STRING Bat cmd

ENTER

STRING Bat cmd

ENTER

STRING Bat cmd

ENTER

STRING Bat cmd

ENTER

It would be really Awesome if we could write a JAVA/PYTHON/C++/C program to do this automatically. A java program could probably serve both as a command line called program, aswell as a GUI program, using a cmd line flag or the prescence of multiple flags to differentiate between the run states.

Shouldn't be too hard, considering that you're just taking input and pasting it into a new script and then outputting to a new file. A little STDIO should do the trick..

Hi,

I just done a little awk for that :)

gedit convert.sh &
chmod +x convert.sh
./convert.sh script.bat[/CODE]

[CODE]
#!/bin/bash
awk 'BEGIN{
print "DELAY 3000\n"\
"GUI R\n"\
"DELAY 300\n"\
"STRING cmd\n"\
"ENTER\n"\
"DELAY 300\n"\
"STRING copy con BATCH.BAT\n"\
"ENTER"
}{
print "STRING "$0"\nENTER"
}
END{
print "CTRL z\n"\
"STRING BATCH.BAT\n"\
"ENTER"
}' $1
[/CODE]

I probably should have mentioned that I use a Windows box, but theres probably windows option for bash...
Im glad that a couple of people were interested in my topic. After I posted this topic I began working on a java solution, and I will post it here. I am working on a GUI option for the java program, right now only command line options work. There are a couple of bugs in the code, like when typing the ^Z character to end the console input you must type it adjacent to text, not on a line by its self. Remember to compile first, then use the java command on the command prompt to run the class.

I had a few problems with uploading the file, so I will just copy and paiste the text here;

Finally finished the full java solution feel free to modify, or improve. Use the -help/-h/-H/-? command line flags for directions on how to use. When inputting a string on the command prompt using the -con flag, remember that the ctrl+z character must be adjacent to the last line of text you wish to input. There is a slight bug in the code that does not allow the ctrl+z character to be recognized if on a line by its self.
