Create Compilation Database on every build

I would like compile_commands.json generation to be triggered by adding a deliberate flag in platformio.ini.

if "compiledb" in COMMAND_LINE_TARGETS:

Existing solution (below) is not great because it changes the VSCode GUI icons' action.

[env]
targets = upload, compiled

I tried to do this using extra_scripts (post):

import subprocess
projectTag = (
    subprocess.run(['pio', 'run','-t','compiledb'])
)

but the build went into infinite loop and started eating up RAM.

Do you run that part of the code under the guard?

if "compiledb" not in COMMAND_LINE_TARGETS: 
    subprocess.run(['pio', 'run','-t','compiledb'])

[dzid26]

Ah, that works great.

[env]
extra_scripts = post:generate_compilation_database.py #for the sonarlint

import subprocess
if "compiledb" not in COMMAND_LINE_TARGETS: #avoids infinite recursion
    subprocess.run(['pio', 'run','-t','compiledb'])

I think this is a great solution. I'm going to close this issue.

Happy coding with PlatformIO! 🚀
