When compiler.nvim detects a mason.build file in the current working directory, Telescope will be populated with all its executable and custom_target entries.

Create a meson.build file in your working directory and copy/paste this:

project('HelloWorld', 'cpp')

# Example of a target
hello_world = executable('hello_world', 'main.cpp')

# Example of custom target to run all tasks
build_all = custom_target('build_all', command: 'echo', output: 'echo', input: [hello_world])

Now let's create the file we are building on the example above: Create main.cpp in the same directory.

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

When you open the compiler you will see the option to run it

And this is the result

In the same way you can run hello world, you can execute any command necessary to build your program.

(optionally) You can define the next globals

Example:

let g:MESON_BUILD_TYPE='release'

Globals persist between Neovim sessions.
