Zed Assembly Syntax

Extension for Zed that adds assembly syntax highlighting and asm-lsp support.

Language Server

You can configure the language server by creating a .asm-lsp.toml in the root of your workspace

Example .asm-lsp.toml for cross-compiled assembly:

[default_config]
assembler = "gas"
instruction_set = "riscv"

[default_config.opts]
compiler = "riscv64-unknown-elf-gcc"

See the asm-lsp README.md for more configuration options

Disabling the Language Server

To disable the language server of this extension, you can add disable = true to your asm-lsp config

.asm-lsp.toml:

disable = true # make sure this isn't under any [header]

# other options...

Note for Windows Users

As a 2025-06-12, there is no prebuild binaries for Windows, so you will need to get asm-lsp and add it to $PATH yourself.
