Landb 🗃

C++ library to save & load variables easily.

Why Landb? 🪧

• It saves time: with landb you don't have to worry about writing and loading your program data, just database.connect("filename.ldb") then database.pull() to read and database.push() to write your variables into filename.ldb.
• It's fast: it's really fast😄
• multi-type arrays: Landb Arrays may contain multiple types of data, even another arrays.
• type-oriented variables: In Landb number=i:1 and number=s:"one" can exist in the same database without conflicts.
• object-oriented variables: Containers allows us to implement object oriented variables such as:

(PersonA:
    Name=s:"Ty"
    Age=i:9
)

(PersonB: 
    Name=s:"Renato"
    Age=i:17
)

What's new in version 2.7? 🎁

• Documentation is available Here.
• lan::anchor_t * set_anchor(lan::anchor_t * anchor), improved 🔩
• bool set(std::string array, size_t index, any const value, lan::db_bit_type type), fixed🔧

Examples ⚙️

Hello world 🤓

#include <iostream>
#include "landb.hpp"

int main(int argc, const char * argv[]) {
    
    lan::db database;
    
    database.set< std::string >("message", "hello world", lan::String);
    
    std::cout << database.get< std::string >("message", lan::String) << std::endl;
    
    return 0;
}

Types 📑

Type	Description
Bool	Boolean
Int	Integer
Long	Big integer
LongLong	Big integer (unsigned)
Float	Real number
Double	Big real number
Char	Character
String	Character sequence
Unsafe	Unsafe data, only exists at runtime and cannot be pushed
Array	Variable sequence
Container	(Similar to namespace in c++) Allows object oriented variables

Landb structure examples 📋

A string containing "hello world".

message = s : "Hello world"

An array with numbers and strings:

numbers = a : [  i : 1  s : "one"  i : 2  s : "two" ]

Compiling 🔨

1. Clone this repo

# 1.1 clone using git:
git clone https://github.com/ReneMuala/landb.git

2. Build with cmake (inside of the project dir)

# 2.1 get in landb foder :
cd landb 

# 2.2 configure cmake :
cmake ./ 

# 2.3 build with cmake :
cmake --build ./

Linking with your project⛓

File	Description	Notes
liblandb.a	Static library	Can be used to link binaries statically with landb
liblandbD.so	Shared library	Can be used to link binaries dynamically with landb

Note: to include landb as #include "landb.hpp" you need to copy landb.hpp to your source's dir.

CMakeLists.txt example:

cmake_minimum_required(VERSION 3.0)
project(sgep)
add_compile_options(-std=c++17)
add_executable(sgep main.cpp)
target_link_libraries(sgep ${CMAKE_SOURCE_DIR}/liblandb.a) # linking with liblandb.a in project source dir
install(TARGETS sgep RUNTIME DESTINATION bin)
