SYNOPSIS

A c++ repl and cli tool for leveldb

BUILD

Mac OS X

$ brew install snappy cmake
$ git clone https://github.com/0x00a/ldb.git
$ make install -C ldb

Linux (Debian / others?)

$ sudo apt-get install libsnappy-dev cmake
$ git clone https://github.com/0x00a/ldb.git
$ cd ldb
$ make && sudo make install

USAGE

Open an existing database with interactive mode (REPL) and create the database if it does not exist with optional flag --create.

ldb ./testdb --create

Use as a commandline interface

ldb -h

KEY AUTO-COMPLETE

ldb will get the first n (as defined in LIMIT) records and make them available for autocomplete. If the limit is redefined, the cache will be refreshed to reflect the new range.

When possible, hitting tab will allow you to cycle though keys that match your partial input. Also, if there is a partial match it will be highlighted in the results.
