Jai bindings for the Tracy profiler v0.11.1

It’s originally based on vrcamillo/jai-tracy, but modified to work as an auto-instrumenting metaprogram plugin (like modules/Iprof).

1. Ensure that the tracy submodule is cloned at the root of the repository.
2. Build the static and shared libraries using jai generate.jai at the root of the repository.

This only works if your project does not contain a custom metaprogram! (i.e. you never call set_build_options_dc({do_output = false})) Otherwise see below.

• Just use this module as a metaprogram plugin by adding -pluging tracy to your compile command. (Assuming that you have cloned this repo into a folder named tracy.)
• If you want to profile modules code (in addition to your application code) you can append the argument -modules.

You might need to add -- import_dir <path_to_modules_folder_that_contains_tracy> if this module does not live in your default modules folder.

If your program has its own metaprogram, you need to add this plugin to your metaprogram, which involves…

1. adding #import "Metaprogram_Plugins",
2. calling Metaprogram_Plugins.init_plugins(…),
3. calling the plugin’s before_intercept, add_source, etc. at the appropriate time.

Take a look at Default_Metaprogram for how to support plugins.

You can even use this plugin to profile your compile-time metaprogram, #run commands, etc. But it requires some inception-style work:

1. Tell the compile to use the Default_Metaprogram with the tracy plugin to compile … the Default_Metaprogram.
2. Then use that second Default_Metaprogram to compile your project.

It looks something like this:

    jai <path_to_jai>/modules/Default_Metaprogram.jai -plug tracy -modules -no_cwd \ # Compile Default_Metaprogram with the tracy plugin
    - <your_normal_entry_file>.jai <your normal compile arguments> \ # Arguments for the second-stage Default_Metaprogram, which is what you would normally pass to the compiler/metaprogram
    -- import_dir <path_to_modules_folder_that_contains_tracy> # Add this if you need to tell the first-stage Default_Metaprogram where to find the tracy module.
