1.1-Lang

Perl interpreter for esolang 1.1

More info can be found at: https://esolangs.org/wiki/1.1

Can be run from the commandline in the form: perl main.pl <commandline args> <scriptfile>

I have created a very simple batch script for Windows so you can run 1p1 <commandline args> <scriptfile> instead. Creating other equally simple shell scripts should not be a problem.

Commandline Args:

• -D = Turn on debug mode.

Script Format:

The first line should be: 1|<starting buffer or nothing>

• 1 being the number of the state followed by a pipe | then the starting buffer.
• If the starting buffer is empty, it takes the starting buffer from STDIN.

The rest of the lines should be in the form: #1|<needle>|<replacement>|#t|#f

• #1 is the state number (this should correspond to the line number in the file.)
• <needle> is the string to search the buffer for (without the brackets).
• <replacement> is the string to replace the <needle> if the <needle> is found.
• <#t> is the state number to jump to if <needle> is found.
• <#f> is the state number to jump to if <needle> is NOT found.

The last line must be in the form: #|Halt

• # being the final state number

Examples

These are included in this repo.

Hello World

1|Good morning you!
2|Good morning|Hello|3|4
3|you|World|4|4
4|halt

1. The buffer is set to Good morning you!.
2. Good morning is found and replaced by Hello.
3. you is found and relaced by World.
4. halt stops the program.
