The program life
A demonstration: Conway's Game of Life.
pointer, left button: draw cells space: pause r: random c: clear
This program is also a service: another program reads and changes the cells with isolated calls, while the game runs.
| Fact | Value |
|---|---|
| Source | programs/life |
| Boot image | in the boot image; the image is not built, so its size is not known |
| Imports | none |
| Imported by | none |
Exports
| Export | What it does |
|---|---|
| population() -> Integer | gives the count of live cells |
| empty() | removes all the cells |
| glider(column: Integer, row: Integer) | adds a glider: five cells that move down and right |
| entry() |
Read from the source of the module, as the build reads it to describe the exports (tools/kerneltool/describe.odin).
What the root service gives it
| What | Value | As the root service says |
|---|---|---|
| Grants | {.Serve} | sample: the module of the tables, started as a program when a caller connects. |
| Budget: pages, programs, threads | {pages = 2048, programs = 1, threads = 1} | Not named in things_of: the budget of each other program. |
Read from grants_of and things_of in programs/root/main.odin; budget_of in the same file adds the limits of processor time and of log records.
