Script for getting a good IDE experience for programming Wine under NixOS. Assumes you are in the Wine folder, and have a ../wine-build.

nix-code-wine.sh

#!/bin/sh
set -e

if [ "$1" = "inside-nix-shell" ]; then
  echo "Clearing clangd cache."
  rm -f "compile_commands.json"
  rm -rf ".clangd"

  LIBEAR32="$(nix-build "<nixpkgs>" -A bear --argstr system i686-linux)/lib/bear/libear.so"
  LIBEAR64="$(nix-build "<nixpkgs>" -A bear --argstr system x86_64-linux)/lib/bear/libear.so"

  echo "Compiling wine."
  (cd ../wine-build &&
    ../wine/configure &&
    make clean &&
    bear -o ../wine/compile_commands.json \
      --libear="${LIBEAR32}:${LIBEAR64}" make -j32)
  echo "Finished compiling wine."

  echo "Installing clangd."
  nix-env -iA nixos.clang-tools

  echo "Executing VSCode."
  exec code .
else
  echo "Running self under nix-shell."
  nix-shell '<nixpkgs>' -A wine --run "./nix-code.sh inside-nix-shell"
