tbucket
group dates into time buckets
This command and API modifies the dates given as input to the nearest bucket for the given time string. This way you can create "buckets" of time to lump events in.
example
$ echo -e '2015-11-24 3\n2015-11-12 4\n2015-11-22 5' \
| tbucket week | sort
2015-11-08 4
2015-11-22 3
2015-11-22 5
api example
var tbucket = require('tbucket')
var timestr = process.argv.slice(2).join(' ')
process.stdin
.pipe(tbucket(timestr))
.pipe(process.stdout)
output:
$ echo -e '2015-11-24 3\n2015-11-12 4\n2015-11-22 5' \
| node lines.js week | sort
2015-11-08 4
2015-11-22 3
2015-11-22 5
api
var tbucket =
var stream = tbucket(timestr, opts)
Create a bucket transform stream from a recurring time string.
Some example values for a time string:
- weekly
- monthly
- yearly
- every tuesday
By default, the stream
expects lines of text as input with leading date
strings and produces lines of text as output.
opts.readableObjectMode
- whentrue
, produce objects as outputopts.writableObjectMode
- whentrue
, expect objects as inputopts.objectMode
- whentrue
, produce objects as output and expect objects as input
In object mode (both read and write), the objects should have both key
and
value
properties.
