Customizing

Prefix

The prefix, what comes before the message, can be changed with the set_prefix method on a Logger structure.

The default prefix is $[datetime] $[level:color]$[level:name]$[reset]:

Placeholders

There are formatting placeholders that will be replaced in both the message and the prefix that can be seen here.

For example, logging the following message

$[fg:red]$[effect:blink]$[effect:bold]$[sys:username] says hello!

Will print a red blinking message in bold that says <username> says hello!, where <username> is the username on your system.

Styling

You can choose whether you want to style your messages or not with the SetStyling method on a Logger structure. Styling includes foreground colors, background colors and special effects such as bold, and others - see the terminal.rs file.

Note: The styling will not apply to the message if it is not supported by the terminal.

Log File

Logs can also be written inside a log file with styling removed. For example:

fn main() {
    let mut logger = tangra::Logger::new();
    logger.set_log_file_path("example.log");
    logger.debug("$[fg:red]$[effect:blink]$[effect:bold]$[sys:username] says hello!");
}
