Any code I do for this series will be here.
|
||||
|
||||
Building requires msvc or llvm's clang + lld, and powershell 7
|
||||
|
||||
|
||||
## Scripts
|
||||
|
||||
* `build.ps1` - Builds the project use `.\scripts\build msvc` or `.\scripts\build clang`, add `release` to build in release mode
|
||||
* `clean.ps1` - Cleans the project
|
||||
* `update.ps1` - Updates the project dependencies to their latest from their respective repos. (Not done automatically on build)
|
||||
|
||||
## Notes
|
||||
|
||||
Building requires msvc or llvm's clang + lld, and powershell 7
|
||||
|
||||
The build is done in two stages:
|
||||
|
||||
1. Build and run metaprogram to scan and generate dependent code.
|
||||
2. Build the handmade hero runtime.
