How We Built Syntax Highlighting for the Terminal Input Editor

The text discusses the development of command entry improvements within Warp's terminal, focusing on syntax highlighting and error underlining. The author shares their exploration of similar features in other tools like zsh-syntax-highlighting or fish shell, as well as text editors and IDEs such as VSCode or IntelliJ IDEA. They identified two key features to tackle: syntax highlighting and error underlining. The author then delves into the technical implementation of these features, discussing challenges like styling text in-place and handling inheritable text styles. They also mention using a custom command parser based on Nushell for command parsing. Finally, they share their excitement about launching these features to all Warp users during their internship.
