# Catch-22
|
||
|
|
A Catch-22 is defined by [wikipedia](https://en.wikipedia.org/wiki/Catch-22_(logic)) as
|
||
|
|
`Catch-22s often result from rules, regulations, or procedures that an individual is subject to, but has no control over, because to fight the rule is to accept it.`
|
||
|
|
|
||
|
|
The Catch-22 in the case of [AbleOS](https://git.ablecorp.us/AbleOS/AbleOS) is
|
||
|
|
`Drivers not being developed so nobody uses AbleOS so drivers are not developed`
|
||
|
|
|
||
|
|
This is a loop that makes it hard to develop for AbleOS and to combat this a singular or small set of developers must toil endlessly to develop a small usable set of drivers to give the layperson something to test out and play around with.
|
||
|
|
|
||
|
|
If people are willing to test and play and hopefully document how they break a system they might also be willing to contribute a couple hundred lines of code to improve or make the beginnings of a new driver.
|
||
|
|
|
||
|
|
AbleOS has a small benefit of being a microkernel with only userspace drivers which push forward the general userspace application tooling as they improve leading to a generally better tooling for all programs.
|
||
|
|
|
||
|
|
|
||
|
|
For example `logging` in AbleOS will be identical between driver and application
|
||
|
|
providing one single simple logging api
|
||
|
|
|
||
|
|
I will not be explaining step by step this API like I have done previously
|
||
|
|
```rust
|
||
|
|
use timestamp::TimeStamp;
|
||
|
|
|
||
|
|
enum LogLevel{
|
||
|
|
Error,
|
||
|
|
Warn,
|
||
|
|
Info,
|
||
|
|
Debug,
|
||
|
|
Trace,
|
||
|
|
}
|
||
|
|
@documentation["This logger is an application specific logger that would stream the logs to the system logger"]
|
||
|
|
struct Logger {
|
||
|
|
@documentation["This history is read+append by default to prevent overwriting previous logs"]
|
||
|
|
history: Vector<(LogLevel, TimeStamp, String)>,
|
||
|
|
enabled: bool,
|
||
|
|
|
||
|
|
last_timestamp: TimeStamp,
|
||
|
|
|
||
|
|
@documentation["Log to the history"]
|
||
|
|
@validator[time: Timestamp > last_timestamp]
|
||
|
|
log: function(log_level: LogLevel, time: TimeStamp, note: String) -> None;
|
||
|
|
|
||
|
|
@documentation["Set the log level filter, which ignores levels below itself. To turn off logging use disable()"]
|
||
|
|
log_level: function(filter: LogLevel) -> None;
|
||
|
|
|
||
|
|
@validator[enabled == false]
|
||
|
|
enable(None) -> None;
|
||
|
|
|
||
|
|
@validator[enabled == true]
|
||
|
|
disable(None) -> None;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
As a driver/app developer this will not change when you swap from one to the other which lowers the bar for writing portable code and that is a giant plus to make it easier for application developers to work on drivers as well.
