For the most part, I like this approach. A couple of tiny changes and I'll be happy to add it. I apologize profusely for the delay. If the original author doesn't show up in a little bit, I'll make the changes myself.

PrioritySelector inspects the list of keyvals, and selects a syslog priority.

Can we do proper import grouping, i.e.
import (
// stdlib
// go-kit
)|
@ChrisHines Any blockers that you see? |

I don't have any experience with the stdlib log/syslog package, or syslog in general, so I don't have any opinion on the use of syslog here.
I like the exported API presented by this package. It matches the style of the other go-kit/log packages. 👍
I found an edge case that will panic which should be fixed.
Otherwise just a few nits and some readability bike shedding.

This line may panic if len(keyvals) is odd and the last element == level.Key().

type syslogWriter doesn't appear to be used anywhere, I think it can be removed.

- Do we need to emphasize that a PrioritySelector may not modify the contents of keyvals?
- For readability of the source code I would move to just before the
func PrioritySelectorOptiondeclaration.

- s/cb/lb to be consistent with variable names in
getLoggerBuf. - I feel like it would help readability to move the
type loggerBuf,func (l *syslogLogger) getLoggerBuf, andfunc (l *syslogLogger) putLoggerBufdeclarations to after thefunc (l *syslogLogger) Logdeclaration because they are couple together more tightly than theOptionsrelated code. I find myself having to skip over theOptionsstuff a lot while reading the code.

I would prefer all of the code in this file be combined with syslog_logger.go and the combined file be renamed to syslog.go. I would put the type SyslogWriter declaration directly above the func NewSyslogLogger declaration.

I implemented all the comments apart from those phrased as questions. I rebased on top of master so tests from other subpackages pass as well. |

Thanks everyone, and sorry again for that inexcusably long delay. |
This is another crack at #333. It incorporates the discussion from #486 but it shares very little code with it. In structure, it's very similar to term.NewColorLogger - it's so similar that
loggerBufcould be extracted and be used b both (but in which package should it live? it would have to be exported which might be confusing?).However, while working on this I realized that it breaks on one the 12 factor app principles. Including it in Go kit might be a promotion of a suboptimal approach, so I'm not sure it should be included at all.
