goce

Go Compiler Explorer similar to Matt Godbolt's godbolt.org, but lighter, easier to set up and with Go specific features.

You can check it out at goce.w1ck3dg0ph3r.dev or run goce locally.

Additional features include:

• showing inlineability analysis (recursion, function complexity cost, etc.)
• showing inlined function calls
• showing variables that escape to heap

Building and running locally

On the host machine

You will need go, node and pnpm to build goce.

make
./goce

Inside the docker container

Build the docker image:

make image

Prepare volume mounts for compilation cache, shared code storage and Go toolchains, module and build caches:

mkdir -p .cache/{goce,sdk,mod,build} && chown -R 1000:1000 .cache

Run the container:

docker run -d \
    --name goce \
    -p 127.0.0.1:9000:9000 \
    -e GOCE_COMPILERS_SEARCH_GO_PATH=false \
    -e GOCE_COMPILERS_SEARCH_SDK_PATH=true \
    -v $PWD/.cache/goce:/opt/data \
    -v $PWD/.cache/sdk:/home/goce/sdk \
    -v $PWD/.cache/mod:/home/goce/go/pkg/mod \
    -v $PWD/.cache/build:/home/goce/.cache/go-build \
    w1ck3dg0ph3r/goce:latest

On the first run there will be no Go toolchains set up. To install 3 latest Go toolchains, run the following and wait around 15s for goce to pick up the downloaded toolchains:

docker exec -it goce /opt/godl -n 3

Alternatively, there is an example compose.yaml file for docker compose.

Configuration

Goce can be configured via:

• goce.toml file located in /etc/goce or ~/.config/goce
• environment variables

See goce.example.toml, .env.example and config.go for details.

Notes:

• Right now goce supports the following go compilers:

  • the one found in $PATH
  • all versions insalled in ~/sdk/go* (the default location for multiple go installations on *nix systems)
  • explicitly specified binary

• goce stores compilation cache and shared code snippets in ./data/cache.db and ./data/shared.db respectively.

  • the format can vary between versions, so you may have to remove these files after upgrading.
