syslog format support

[laoshaw]

bat will be really useful if it can view log files with highlighting, e.g. ERROR/error, WARNING/warning are in different colors(ERROR: red, WARNING: yellow) etc.

Thank you for the feedback.

That sounds like a really cool idea! We would need to look for (or create) a Sublime Text syntax that would do the appropriate highlighting. This could then be used with bat -l log on all kinds of text files.

Here you can find a sublime syntax for syslog. Maybe @ufo22940268 could help.

@caos21 That looks good.

If someone wants to add this, please follow the steps in the README here: https://github.com/sharkdp/bat/tree/master/assets

Thanks. I will take a look at it.

I updated the syslog-syntax. #470

This doesn't seem to work for /var/log/syslog on Linux. Is there anything I could do to have warnings highlighted, as that would make viewing syslogs a lot easier?

[sharkdp]

I think we should probably open a new issue for this. I would also love to have a better log-file highlighting. The current log syntax has a rather strict format. It would probably be better to simply highlight things like Warning, WARN, Error, ERR, etc.
