Instructions

Args:
    language: Programming language to get compilers for (e.g., 'cpp', 'rust')

Returns:
    List of unversioned compiler names available for the language

Raises:
    HTTPException: If the API request fails

Example:
    >>> await list_compilers_for_language("cpp")
    ["gcc", "clang", "msvc"]

Implementation Reference

• server.py:283-307 (handler)

  The main handler function for the 'list_compilers_for_language' tool, decorated with @mcp.tool() for registration. It fetches compilers for the specified language using ce_client, extracts unversioned names, and returns a unique list.

  @mcp.tool()
  async def list_compilers_for_language(language: str) -> list[str]:
      """Get available compilers for a specific programming language.
  
      Args:
          language: Programming language to get compilers for (e.g., 'cpp', 'rust')
  
      Returns:
          List of unversioned compiler names available for the language
  
      Raises:
          HTTPException: If the API request fails
  
      Example:
          >>> await list_compilers_for_language("cpp")
          ["gcc", "clang", "msvc"]
      """
      try:
          compilers = await ce_client.list_compilers(language)
          return list(
              {get_unversioned_compiler_name(c["name"], c["semver"]) for c in compilers}
          )
      except CompilerExplorerError as e:
          raise HTTPException(status_code=e.status_code, detail=str(e))

• server.py:196-213 (helper)

  Helper utility function used by the handler to derive unversioned compiler names from full names and semantic versions.

  def get_unversioned_compiler_name(compiler_name: str, semver: str) -> str:
      """Get the unversioned compiler name from the versioned name.
  
      Args:
          compiler_name: Full compiler name including version
          semver: Version string to remove
  
      Returns:
          Cleaned compiler name without version information
  
      Example:
          >>> get_unversioned_compiler_name("gcc-12.2", "12.2")
          "gcc"
      """
      return (
          compiler_name.replace(semver, "").replace("none", "").replace("()", "").strip()
      )
