# d_logger
A rust crate providing simple logging with a dated clean up util.
## Examples
Create a logger with 7 days of cleaning
```rust
use d_logger::Logger;
let logger = Logger::new("C:/logs/".to_string(), "Log%d%m%y.log".to_string(), "%Y-%m-%d %H:%M:%S".to_string(), Some(7)).unwrap();
if !logger.write_log("This is a test log entry") {
panic!("Logger failed");
}
// This will work
logger.log_clean(None);
```
Create a logger without any cleaning
```rust
use d_logger::Logger;
let logger = Logger::new("C:/logs/".to_string(), "Log%d%m%y.log".to_string(), "%Y-%m-%d %H:%M:%S".to_string(), None).unwrap();
if !logger.write_log("This is a test log entry") {
panic!("Logger failed");
}
// This will fail
logger.log_clean(None);
```
Clean logs with a regex filter
```rust
use d_logger::Logger;
let logger = Logger::new("C:/logs/".to_string(), "Log%d%m%y.log".to_string(), "%Y-%m-%d %H:%M:%S".to_string(), Some(7)).unwrap();
if !logger.write_log("This is a test log entry") {
panic!("Logger failed");
}
// This will work
logger.log_clean(Some(r"example_test_\d{8}.log"));
```
## Functions
### new(path: String, file_name_format: String, line_date_format: String, days_keep: Option<u64>) -> Result<Logger, io::error>
Create a new logging structure and test that the path and file given can be accessed.
### write_log(line: String) -> bool
Write a line to the log file. Will return whether its successful
### log_clean(regex: Option<&str>)
Clean up the log directory. If regex is provided only files matching regex will be deleted.
Will only delete anything if days_keep was set. The files delete must be older than the number of days wanted to keep.
