# v2
|
||||
|
||||
- ^C fix. Done in 1.8.9. However, see a recent ticket about ^C/EPIPE issues.
|
||||
I suspect the uncommited exeunt work will fix that.
|
||||
- node-exeunt
|
||||
- Exit handling:
|
||||
|
||||
- make a ticket with notes from "bunyan CLI exit handling" section below
|
||||
- resolve it with the uncommited changes here
|
||||
|
||||
- figure out how to 'make cutarelease' for 2.x but tag as beta
|
||||
- comment/grokking of bunyan.js flushing issues at
|
||||
https://github.com/trentm/node-bunyan/issues/37 would be nice. Even if just a
|
||||
link to exeunt and some examples. Wiki page?
|
||||
- respond to Qs here: https://github.com/trentm/node-bunyan/issues/37#issuecomment-282933502
|
||||
- consider whether to backport the exit handling work to 1.x???
|
||||
- `createLogger(<config-and-fields>, <fields>)` changes (#460)
|
||||
- see section below
|
||||
- the dtrace-provider thing (#487)
|
||||
TODO: answer Cody email
|
||||
- https://github.com/trentm/node-bunyan/issues/398 if easy, perhaps on 1.x
|
||||
as well
|
||||
- use package.json version for VERSION
|
||||
- use deps
|

- dashdash

- formatters: read up again on `glp master..1.x`
|
||||
- support for customer formatters
|
||||
- for the CLI as well? How? ~/.bunyanrc?
|

- if doing ~/.bunyanrc, then consider color schemes

# bunyan CLI exit handling
|
||||
|
||||
It has some problems currently.
|
||||
|
||||
One basic problem is that our stdout.on('error') handler can call into
|
||||
drainStdoutAndExit multiple times, leading to the multiple Event Emitters
|
||||
leak warning, and with a pager we are waiting for the pager to exit.
|
||||
Why doesn't the pager exit on ^C? Is that a less thing? Perhaps due to our
|
||||
LESS opts?
|
||||
|

Setting up a file to work with:
|
||||
|
||||
```javascript
|
||||
$ cat lots.js
|
||||
var bunyan = require('./')
|
||||
var log = bunyan.createLogger({
|
||||
name: 'lots',
|
||||
streams: [
|
||||
{
|
||||
type: 'file',
|
||||
path: './lots.log'
|
||||
}
|
||||
]
|
||||
});
|
||||
|
||||
N = Math.pow(2, 16);
|
||||
for (var i = N; i >= 0; i--) {
|
||||
log.info({i: i}, 'another record');
|
||||
}
|
||||
|
||||
$ node lots.js
|
||||
```
