A Nim wrapper for [Facebook's RocksDB](https://github.com/facebook/rocksdb), a persistent key-value store for Flash and RAM Storage.
## Current status
Nim-RocksDB provides a wrapper for the low-level functions in the librocksdb c library.
## Installation
Nim-RocksDB requires Nim and the Nimble package manager. For Windows you will need Visual Studio 2015 Update 3 or greater with the English language pack.
To get started run:
```
nimble install
```
This will download and install the RocksDB dynamic libraries for your platform and copy them into the `build/` directory of the project. When including this library in your application you may want to copy these libraries into another location or set the LD_LIBRARY_PATH environment variable (DYLD_LIBRARY_PATH on MacOS, PATH on Windows) to include the `build/` directory so that your application can find them on startup.
Alternatively you can use the `rocksdb_static_linking` flag to statically link the library into your application.
### Static linking
To build the RocksDB static libraries run:
```
./scripts/build_static_deps.sh
```
To statically link RocksDB, you would do something like:
```
nim c -d:rocksdb_static_linking --threads:on your_program.nim
```
See the config.nims file which contains the static linking configuration which is switched on with the `rocksdb_static_linking` flag. Note that static linking is currently not supported on windows.
## Usage
