##git mergetool

In the middle file (future merged file), you can navigate between conflicts with ]c and [c.

Choose which version you want to keep with :diffget //2 or :diffget //3 (the //2 and //3 are unique identifiers for the target/master copy and the merge/branch copy file names).

:diffupdate (to remove leftover spacing issues)

:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)

{-# LANGUAGE OverloadedStrings #-}

Tokenizer for SLF0 serialization format, used by Xcode to, at the very least,
encode some log files.
For example, `.xcactivitylog` logs are gzipped files of this format,
serializing some objc classes which represent the build log.
This class tokenizes the raw byte stream into a flat list of tokens. The actual
