# levigo

levigo is a Go wrapper for LevelDB.

The API has been godoc'ed and [is available on the

web](http://godoc.org/github.com/jmhodges/levigo).

Questions answered at `[email protected]`.

## Building

You'll need the shared library build of

[LevelDB](http://code.google.com/p/leveldb/) installed on your machine. The

current LevelDB will build it by default.

The minimum version of LevelDB required is currently 1.7. If you require the

use of an older version of LevelDB, see the [fork of levigo for LevelDB

1.4](https://github.com/jmhodges/levigo_leveldb_1.4). Prefer putting in the

work to be up to date as LevelDB moves very quickly.

Now, if you build LevelDB and put the shared library and headers in one of the

standard places for your OS, you'll be able to simply run:

    go get github.com/jmhodges/levigo

But, suppose you put the shared LevelDB library somewhere weird like

/path/to/lib and the headers were installed in /path/to/include. To install

levigo remotely, you'll run:

    CGO_CFLAGS="-I/path/to/leveldb/include" CGO_LDFLAGS="-L/path/to/leveldb/lib" go get github.com/jmhodges/levigo

and there you go.

In order to build with snappy, you'll have to explicitly add "-lsnappy" to the

`CGO_LDFLAGS`. Supposing that both snappy and leveldb are in weird places,

you'll run something like:

    CGO_CFLAGS="-I/path/to/leveldb/include -I/path/to/snappy/include"

    CGO_LDFLAGS="-L/path/to/leveldb/lib -L/path/to/snappy/lib -lsnappy" go get github.com/jmhodges/levigo

(and make sure the -lsnappy is after the snappy library path!).

Of course, these same rules apply when doing `go build`, as well.

## Caveats

Comparators and WriteBatch iterators must be written in C in your own

library. This seems like a pain in the ass, but remember that you'll have the

LevelDB C API available to your in your client package when you import levigo.

An example of writing your own Comparator can be found in

.
