Compiler Explorer

Compiler Explorer

Compiler Explorer is an interactive compiler. The left-hand pane shows editable C, C++, Rust, Go, D, Haskell, Swift and Pascal code. The right, the assembly output of having compiled the code with a given compiler and settings. Multiple compilers are supported, and the UI layout is configurable (thanks to GoldenLayout). There is also an ispc compiler ? for a C variant with extensions for SPMD.

Try out at godbolt.org

Compiler Explorer follows a Code of Conduct which aims to foster an open and welcoming environment.

Developing

Compiler Explorer is written in Node.js.

Assuming you have a compatible version of node installed, simply running make ought to get you up and running with an Explorer running on port 10240 on your local machine: http://localhost:10240/. Currently Compiler Explorer requires the latest LTS node version (v8) installed, either on the path or at NODE_DIR (an environment variable or make parameter).

Running with make EXTRA_ARGS='--language LANG' will allow you to load LANG exclusively, where LANG is one for the language ids/aliases defined in lib/languages.js. The Makefile will automatically install all the third party libraries needed to run; using yarn to install server-side and client side components.

The config system leaves a lot to be desired. Work has been done on porting CCS to Javascript and then something more rational can be used.

A Road map is available which gives a little insight into the future plans for Compiler Explorer.

Running a local instance

If you want to point it at your own GCC or similar binaries, either edit the etc/config/LANG.defaults.properties or else make a new one with the name LANG.local.properties, subsituting LANG as needed. *.local.properties files have the highest priority when loading properties.

When running in a corporate setting the URL shortening service can be replaced by an internal one to avoid leaking source code outside of the organization. This is done by adding a new module in static/urlshorten-myservice.js and setting the urlShortenService variable in configuration. This module should export a single function, see the google module for an example. urlShortenService can also be set to none to disable url shortening altogether.

RESTful API

There's a simple restful API that can be used to do compiles to asm and to list compilers.

You can find the API documentation here.
