## language.extensions

* Get a list of code suffixes for all languages

#### Function Prototype

::: tip API

```lua
language.extensions()
```

:::

#### Parameter Description

No parameters required for this function.

#### Return Value

| Type | Description |
|------|-------------|
| table | Returns a table with file extensions as keys and language source types as values |

#### Usage

Get a list of code suffixes for all languages.

The results are as follows:

```lua
{
    [".c"] = cc,
    [".cc"] = cxx,
    [".cpp"] = cxx,
    [".m"] = mm,
    [".mm"] = mxx,
    [".swift"] = sc,
    [".go"] = gc
}
```

## language.targetkinds

* Get a list of target types in all languages

#### Function Prototype

::: tip API

```lua
language.targetkinds()
```

:::

#### Parameter Description

No parameters required for this function.

#### Return Value

| Type | Description |
|------|-------------|
| table | Returns a table with target types as keys and lists of supported linkers as values |

#### Usage

Get a list of target types in all languages.

The results are as follows:

```lua
{
    binary = {"ld", "gcld", "dcld"},
    static = {"ar", "gcar", "dcar"},
    shared = {"sh", "dcsh"}
}
```

## language.sourcekinds

* Get a list of source file types in all languages

#### Function Prototype

::: tip API

```lua
language.sourcekinds()

#### Return Value

| Type | Description |
|------|-------------|
| table | Returns a table with source file types as keys and file extensions or extension lists as values |

#### Usage

Get a list of source file types in all languages.

The results are as follows:

```lua
{
    cc = ".c",
    cxx = {".cc", ".cpp", ".cxx"},
    mm = ".m",
    mxx = ".mm",
    sc = ".swift",
    gc = ".go",
    rc = ".rs",
    dc = ".d",
    as = {".s", ".S", ".asm"}
}
```

## language.sourceflags

* Load a list of source file compilation option names for all languages

#### Return Value

| Type | Description |
|------|-------------|
| table | Returns a table with source file types as keys and compilation option name lists as values |

#### Usage

Load a list of source file compilation option names for all languages.

The results are as follows:

```lua
{
    cc = {"cflags", "cxflags"},
    cxx = {"cxxflags", "cxflags"},
    ...
}
```

## language.load

* Load the specified language

#### Function Prototype

:::

#### Parameter Description

| Parameter | Description |
|-----------|-------------|
| name | Required. Language name, e.g., "c++", "c" |

#### Return Value

| Type | Description |
|------|-------------|
| language | Returns a language object, or nil if it doesn't exist |

#### Usage

Load a specific language object from the language name, for example:

```lua
local lang = language.load("c++")
if lang then
    print(lang:name())
end
```

## language.load\_sk

* Load the specified language from the source file type

#### Function Prototype

::: tip API

```lua
language.load_sk(sourcekind: <string>)
```

:::

#### Parameter Description

| Parameter | Description |
|-----------|-------------|
| sourcekind | Required. Source file type, e.g., "cc", "cxx", "mm" |

#### Return Value

| Type | Description |
|------|-------------|
| language | Returns a language object, or nil if it doesn't exist |

#### Usage

Load specific language objects from the source file type: `cc, cxx, mm, mxx, sc, gc, as ..`, for example:

```lua
local lang = language.load_sk("cxx")
if lang then
    print(lang:name())
end
```

## language.load\_ex

```lua
language.load_ex(extension: <string>)
```

:::

#### Parameter Description

| Parameter | Description |
|-----------|-------------|
| extension | Required. Source file extension, e.g., ".cpp", ".c" |

#### Return Value

| Type | Description |
|------|-------------|
| language | Returns a language object, or nil if it doesn't exist |

#### Usage

Load specific language objects from the source file extension: `.cc, .c, .cpp, .mm, .swift, .go ..`, for example:

```lua
local lang = language.load_ex(".cpp")
if lang then
    print(lang:name())
end
```

## language.sourcekind\_of

* Get the source file type of the specified source file
