duino-vscode-settings 0.0.4

A tool for creating VSCode c_cpp_properties.json files.

duino_vscode_settings

Creates a vscode settings file with all of the compiler defines and include paths in it.

This program works by taking the command uses to invoke the compiler (with all of the -D, -I etc options) and it parses the options and generates a VSCode settings file (more precisely, a c_cpp_properties.json file).

duino_vscode_settings also supports storing multiple configurations, so you can have a configuation for running the host compiler (say to run a C++ test suite), and have a configuration for each type of Arduino Board that you use.

duino_vscode_settings will tries to merge any existing options so as not to overwrite customizations.

Installation

pip3 install duino_vscode_settings

or

python3 -m pip install diono_vscode_settings

GitHub Repository

You can find the source code on github

Typical Usage

make-vscode-settings ./.vscode/c_cpp_properties.json -- g++ -DFOO -IsomePath -IotherPath

will generate a c_cpp_properties.json which looks something like this:

{
    "configurations": [
        {
            "cStandard": "gnu11",
            "compilerPath": "g++",
            "cppStandard": "g++17",
            "defines": [
                "FOO"
            ],
            "includePath": [
                "somePath",
                "otherPath"
            ],
            "intelliSenseMode": "gcc-arm",
            "mergeConfigurations": true,
            "name": "Arduino"
        }
    ]
}

Using a NeoPixelExample compiled for a WaveShare RP2040 Zero, I would normally compile this using something like:

arduino-cli compile --fqbn rp2040:rp2040:waveshare_rp2040_zero

If you pass in the --verbose then arduino-cli will print out the compiler invocations. If you grab the one for the .ino file then I use that.

arduino-cli compile --verbose --fqbn rp2040:rp2040:waveshare_rp2040_zero 2>/dev/null | grep g++ | grep .ino.cpp | grep -v -- -lc | tail -1

This will produce this output:

/home/dhylands/.arduino15/packages/rp2040/tools/pqt-gcc/2.3.0-dfd82b2/bin/arm-none-eabi-g++ \

If you assigned the above to a variable called COMPILER_CMD then I would run make-vscode-settings like this:

COMPILER_CMD=$(arduino-cli compile --verbose --fqbn rp2040:rp2040:waveshare_rp2040_zero 2>/dev/null | grep g++ | grep .ino.cpp | grep -v -- -lc | tail -1)
make-vscode-settings -c Arduino-zero ./.vscode/c_cpp_properties.json -- ${COMPILER_CMD}

and that would generate ./.vscode/c_cpp_properties.json with contents something like this:

I typically make a seperate VSCode workspace for each Arduino project, and when I open the workspace and then select Arduino-zero in the bottom right corner. All of the red-squiggles should be gone, and you can Control-Click on a symbol and it takes you to the place where it's defined.
