Clone this repository and run cargo build --release to get compiled bianry.
Add export XSECURELOCK_SAVER="${PATH_OF_COMPILED_BINARY}" to your lock script.
#!/bin/sh
# omit other settings ...
export XSECURELOCK_SAVER="${PATH_OF_COMPILED_BINARY}"
xsecurelock
The module also have some options can be passed by environment variables.
| env name | default value | meaning |
|---|---|---|
| CGOL_CELL_SIZE | 5 | How many pixel per cell have. Smaller size allows more cells to be displayed on the screen. |
| CGOL_INIT_ALIVE_PROBABILITY | 0.2 | Initialize cells by random, this value will be the alive probability of cell. |
| CGOL_INIT_RLE_FILE | Use RLE file to initialize cells, this setting will override CGOL_INIT_ALIVE_PROBABILITY. |
|
| CGOL_MUTATION_ROUND_INTERVAL | 0 | How many rounds between mutations, if it is equals zero, the mutation will never be triggered. The mutation will randomly flip the cell's status, letting the game won't be stuck in a repeating loop. |
| CGOL_MUTATION_PROBABILITY | 0.001 | The probability of cell mutation. |
| CGOL_ROUND_SLEEP_TIME | 0.1 | Sleep time between rounds. |
The default position of pattern is the top-left corner. You can use base_x and base_y to adjust the position of pattern.
e.g. x = 19, y = 10, rule = b3/s23, base_x = 10, base_y = 20, will move pattern 10 cells to the right and move pattern 20 cells down.
You can also change the base coordinate by using center. e.g. x = 19, y = 10, rule = b3/s23, base_x = 1, base_y = 0, center = true.
Now the base_x / base_y's movement are based on the center point of monitor.
