# luaman.h
## Get started
1. Fetch luaman.h
```bash
wget https://raw.githubusercontent.com/IncludeOnly/luaman.h/refs/heads/main/luaman.h
```
2. Build lua library
```bash
git clone https://github.com/lua/lua
cd lua
make all
```
3. Add lua to your project
```bash
mkdir -p lib/lua/include
cp lua/liblua.a lib/lua
cp lua/*.h lib/lua/include
rm -rf lua # We don't need the lua source code anymore
```
4. Link and include
```make
CFLAGS += -Ilib/lua/include
LDFLAGS += -Llib/lua -l:liblua.a -lm
```
## Example
```c
#include
#include
#define LUAMAN_IMPLEMENTATION
#include "luaman.h"
int sub(lua_State* L)
{
lua_Number arg_2 = lua_tonumber(L, -1);
lua_Number arg_1 = lua_tonumber(L, -2);
lua_Number result = arg_1 - arg_2;
lua_pushnumber(L, result);
return 1;
}
int main(){
LuaMan lm = {0};
LMInit(&lm);
LMPushFunction(&lm, sub, "sub");
LMPushNumber(&lm, 420, "bar");
if (!LMRunFile(&lm, "script.lua")) {
fprintf(stderr, "[ERRO] %s\n", lua_tostring(lm.state, -1));
return 1;
}
// Get lua number variable
double foo = LMGetNumber(&lm, "foo");
printf("foo = %lf\n", foo);
// Get lua string variable
const char* home = LMGetString(&lm, "home");
printf("home = %s\n", home);
// Run lua function
LMCallFunctionBegin(&lm, "add", 2, 1)
LMParamNumber(&lm, 35);
LMParamNumber(&lm, 35);
LMCallFunctionEnd(&lm)
double result = LMGetNumber(&lm, NULL);
printf("add(34, 35) = %.0lf\n", result);
// Read lua table
const char* table = "config";
const char* root = LMGetTableFieldString(&lm, table, "root");
const char* wm = LMGetTableFieldString(&lm, table, "wm");
const char* terminal = LMGetTableFieldString(&lm, table, "terminal");
const char* editor = LMGetTableFieldString(&lm, table, "editor");
printf("Config {\n");
printf("\troot: %s\n", root);
printf("\twm: %s\n", wm);
printf("\tterminal: %s\n", terminal);
printf("\teditor: %s\n", editor);
printf("}\n");
LMClose(&lm);
return 0;
}
```
## If you really need to link
```bash
mv luaman.h luaman.c
cc -o libluaman.so luaman.c -fPIC -DLUAMAN_IMPLEMENTATION -shared
mv luaman.c luaman.h
```
