Simulate the digital rain from "The Matrix"
call in terminal with command neo-matrix
Q: neo displays garbage characters on the screen. How can this be fixed?
A: neo will attempt to use half-width katakana characters by default. You may not have a font installed that can display them correctly, or your terminal might not support Unicode well. Try "--charset=ascii" or changing your font. You may also need to use the "--colormode=0" option to disable color.
Q: Colors aren't working. How can this be fixed?
A: Make sure your terminal supports colors. Double check if you need to set the TERM environment variable to enable colors. You may want to try the "--colormode" option.
Q: How do I disable the blinking characters?
A: Use the --noglitch option.
Q: Can I make the text scroll faster or slower?
A: Yes, use the -S/--speed option. Also, the UP and DOWN keys change the speed. The --async option may be fun to try.
Q: How do I change the colors?
A: Use the -c/--color option (e.g. "-c red"). The number keys also change the color while running. Check out the "COLOR FILE" section in the manual if you want to customize neo with your own colors.
Q: How do I change the characters displayed?
A: Use the --charset and/or --chars option. You may also need to use the -F/--fullwidth option depending on the characters you selected.
Q: How do I display a message in the center of the screen?
A: Use the -m/--message option. Don't forget to use double quotes!
Q: neo just shows simple ASCII characters. How can I make it show Unicode characters?
A: neo detects if your locale supports Unicode. Typically, your $LANG environment variable should have "UTF" somewhere if it does (e.g. "en_US.UTF-8"). You can use commands such as localectl to change these settings. You can force neo to attempt to use Unicode by setting a custom charset (e.g. --charset=extended), but this still may not work due to other OS and terminal settings.
