Yadsil

Yet another dead-simple log, on stderr, for CLI tools. Only when on a TTY, enable colors. Only when not on a TTY, prefix each output with the CLI tool name. Possibility to reactivate colors when not on a TTY (it's up to you to provide a --color option or something). That's all.

Install

$ npm install yadsil --save

Usage

log = require('yadsil')('my-tool-name');
// Enable verbose: just display `info` and `debug` messages.
log.verbose(true);
// Force colors (just needed when not in a TTY).
log.color(true);
// Exit after the message.
log.fatal(1, 'exit with %s', 'one');
// Basic messages.
log.error('foo');
log.warning('bar')
log.notice('baz');
log.info('dru');
log.debug('waf');

That's all.

Limitations

No log levels, no fancy features, not timestamps. Just the bare minimum on top of stderr, and will stay that way.
