Multilog

a fun and collateral way to print logs

Each statement you log is associated to a tag, and some tags can be associated to writable streams.

You can also file tags under other tags, so that all statements in a child tag are printed to the parent tag's writable stream!

API

var log = require('multilog');
log('Curse your sudden but inevitable betrayal!', 'stderr');

You get the following functions:

• log(statement, tag) function prints statement in tag channel (defaulting to the special "stdout" channel).
• log.pipe(parentTag, tag) makes all parentTag statements be on the tag channel.
• log.unpipe(parentTag, tag) undoes the corresponding pipe operation.

By default, pipes flow into void.

You can connect them to a writable stream with log.pipe(tag, process.stdout).

You can also ask that their logs be retained with log.retain(tag). You can then read from them (and from all tags that feeds to them) through log.read(tag), and flush the memory with log.flush(tag).

Advanced use:

• log.tags(statement, tagList) prints statement on multiple tags.
• log.stream(tag) returns a duplex Stream for a retained tag.

There are two special tags, stdout and stderr, which directly flush their statements to the corresponding pipeline.
