yacon

This is yet another console logging / debugging module. It has the following features:

• util.format() formatting.
• Optional timestamping.
• Optional call site printing.
• Optional coloring.
• Debug output can be enabled in code or via environment variable.

Functions

enableDebug()

Enables output of .debug() calls and adds callsite information to all lines. Can also be enabled by setting the environment variable DEBUG to anything.

enableTimestamps()

Enables output of ISO8601 timestamps at the start of every line. Can also be enabled by setting the environment variable DEBUG to timestamps.

debug(), ok(), info(), warning(), error(), fatal()

Output the arguments in the same way as util.format(), preceded by the specified level keyword. debug() will be silent unless debug output has been enabled. fatal() will never return.

Example

var con = require('./lib/yacon.js');
 
function main() {
    con.debug('Debug output: %j', {obj: {foo: 42}});
    con.ok('Good stuff');
    con.info('Informational');
    con.warning('Warning');
    con.error('Error');
    con.fatal('Fatal (program will exit)');
    con.info('We never get here');
}
 
main();
