README.md
Welcome to the 4coder code base.
This codebase was authored by Allen Webster from 2014-2022, with help from a number of contributors:
- Casey Muratori
- "insofaras" Alex Baines
- Yuval Dolev
- Ryan Fleury
Also thanks to all those who supported the project, financially and/or through all your detailed feedback.
As of May 31st 2022, I am freezing this codebase and open sourcing it.
I DO NOT recommend learning from this codebase, especially not with an uncritical eye. It may be a useful reference for certain algorithms and architectural ideas, and it certainly contains some cautionary tales. But if you are a beginner, I encourage you to aim for more than emulating the style and structure of this codebase.
I will not be taking pull requests, or any other form of contribution in this repository. Since I am no longer maintaining this codebase, it is my intention that users who rely on 4coder will have the option to fork the codebase, fix their issues, or carry what I started in new directions according to their own vision if they would like.
The license I chose for this codebase is the very permissive MIT license. For the sake of clarity in the community of 4coder users, I ask that new forks of this codebase be given unique names.
In this readme you will find:

Build Instructions
- Create an empty folder named "4ed" to contain the codebase.
- Clone the repository
- Rename the folder containing the repository to "code"
- At the same level as the "4ed" folder, clone the "4coder-non-source" repository
- A. On windows setup the visual studio command line magic sauce so that "cl" works B. On linux setup g++ C. On mac setup clang
- Navigate to the "4ed/code" folder.
- A. On windows run "bin\build.bat" B. On linux run "bin\build-linux.sh" C. On linux run "bin\build-mac.sh"
Notes on Major Issues
-
The build system and organization of files is extremely complicated. There is a 4ed_build.cpp that defines how builds run, and the build scripts have to build and run this C++ file. The file is pretty chaotic since it cannot rely on the codebase's usual helpers. On top of that there is a totally separate build system for the custom layer which is also a big gigantic mess of its own. It involves several stages of compilation, and a number of metaprograms.
-
The documentation system is over complicated & the documentation is incomplete. There is very little documentation for the internals or the complicated layers of helpers.
-
The lexer generator is way too complicated, and the built-in support for language features is not fully developed. The background threaded parsing is not very carefully organized and is not very flexible, so it's hard to add new languages at any level of the system.
-
There are a few layers of overcomplicated configuration parsers.
-
Mac support has not been maintained for several versions.
-
The codebase has a very weak base layer with key features that were added very late, so lots of code was written in the absence of useful features to bind things together. To make matters worse the base layer is split by the distinction of custom layer & core layer, leading to some double definitions and some incosistencies.
