jh-bunyan - npm Package Versions

[issues #105, #138, #151] Export <Logger>.addStream(...) and <Logger>.addSerializers(...) to be able to add them after Logger creation. Thanks @andreineculau!

[issue #159] Fix bad handling in construtor guard intending to allow creation without "new": var log = Logger(...). Thanks @rmg!

[issue #156] Smaller install size via .npmignore file.

[issue #126, #161] Ignore SIGINT (Ctrl+C) when processing stdin. ...| bunyan should expect the preceding process in the pipeline to handle SIGINT. While it is doing so, bunyan should continue to process any remaining output. Thanks @timborodin and @jnordberg!

[issue #160] Stop using ANSI 'grey' in bunyan CLI output, because of the problems that causes with Solarized Dark themes (see https://github.com/altercation/solarized/issues/220).

[issue #87] Backward incompatible change to -c CODE improving performance by over 10x (good!), with a backward incompatible change to semantics (unfortunate), and adding some sugar (good!).

The -c CODE implementation was changed to use a JS function for processing rather than vm.runInNewContext. The latter was specatularly slow, so won't be missed. Unfortunately this does mean a few semantic differences in the CODE, the most noticeable of which is that this is required to access the object fields:

  # Bad. Works with bunyan 0.x but not 1.x.
  $ bunyan -c 'pid === 123' foo.log
  ...

  # Good. Works with all versions of bunyan
  $ bunyan -c 'this.pid === 123' foo.log
  ...

The old behaviour of -c can be restored with the BUNYAN_EXEC=vm environment variable:

  $ BUNYAN_EXEC=vm bunyan -c 'pid === 123' foo.log
  ...

Some sugar was also added: the TRACE, DEBUG, ... constants are defined, so one can:

  $ bunyan -c 'this.level >= ERROR && this.component === "http"' foo.log
  ...

And example of the speed improvement on a 10 MiB log example:

  $ time BUNYAN_EXEC=vm bunyan -c 'this.level === ERROR' big.log | cat >slow

  real    0m6.349s
  user    0m6.292s
  sys    0m0.110s

  $ time bunyan -c 'this.level === ERROR' big.log | cat >fast

  real    0m0.333s
  user    0m0.303s
  sys    0m0.028s

The change was courtesy Patrick Mooney (https://github.com/pfmooney). Thanks!

Add bunyan -0 ... shortcut for bunyan -o bunyan ....

[issue #135] Backward incompatible. Drop dtrace-provider even from optionalDependencies. Dtrace-provider has proven a consistent barrier to installing bunyan, because it is a binary dep. Even as an optional dep it still caused confusion and install noise.

Users of Bunyan on dtrace-y platforms (SmartOS, Mac, Illumos, Solaris) will need to manually npm install dtrace-provider themselves to get Bunyan's dtrace support to work. If not installed, bunyan should stub it out properly.
