Buttons Export / Import Table

The two buttons Import table and Export table allow to save and respectively reload a truth table definition.

The information is stored in a TEXT file of this format:

a b c_in | s c_out
~~~~~~~~~~~~~~~~~~
0 0  0   | 0   0  
0 0  1   | 1   0  
0 1  0   | 1   0  
0 1  1   | 0   1  
1 0  0   | 1   0  
1 0  1   | 0   1  
1 1  0   | 0   1  
1 1  1   | 1   1

Les règles suivantes s'appliquent:

• Everything after a '#' is a comment and will be ignored.
• Blank lines and separator lines (e.g., ~~~~~~) are ignored.
• Keep column names simple (no spaces, punctuation, etc.).
• Name[N..0]' indicates an N+1 bit variable, while 'Name' by itself indicates a 1 bit variable.
• You can use 'x' or '-' to indicate which input and output bits to ignore.
• You can use binary notation (for example, '10100011xxxx') or hexadecimal notation (for example, 'C3x'). Logisim will determine which is which.

You can export the table to a file, modify it and re-import it. This can be a useful aid for complex tables.
