name: add_languages
returns: bool
description: |
Add programming languages used by the project.
This is equivalent to having
them in the `project` declaration. This function is usually used to
add languages that are only used under some conditions.
Returns `true` if all languages specified were found and `false` otherwise.
If `native` is omitted, the languages may be used for either build or host
machine, but are never required for the build machine. (i.e. it is equivalent
to `add_languages(*langs*, native: false, required: *required*) and
add_languages(*langs*, native: true, required: false)`. This default behaviour
may change to `native: false` in a future Meson version.
example: |
```meson
project('foobar', 'c')
if compiling_for_osx
add_languages('objc')
endif
if add_languages('cpp', required : false)
executable('cpp-app', 'main.cpp')
endif
# More code...
```
varargs:
type: str
name: Language
description: The languages to add
kwargs:
required:
type: bool
default: true
description: |
If set to `true`, Meson will halt if any of the languages
specified are not found. *(since 0.47.0)* The value of a
[`feature`](Build-options.md#features) option can also be passed.
native:
type: bool
since: 0.54.0
description: |
If set to `true`, the language will be used to compile for the build
machine, if `false`, for the host machine.
