history

Project history and usage

asm-lsp is a Rust language server for assembly code. Its README says it supports NASM, GAS, Go assembly, MASM, ca65, AVR, FASM, and several instruction-set families including x86, ARM, RISC-V, z80, AVR, and 6502.

Project history

The GitHub repository was created in July 2020, in the period when editors increasingly standardized on Language Server Protocol integrations. The project applies that model to assembly source, where hover help, completions, diagnostics, and references are useful but historically fragmented by assembler dialect.

The README documents a configuration-centered design: project-local `.asm-lsp.toml` files override global config under `~/.config/asm-lsp/`, and `compile_commands.json` or `compile_flags.txt` can extend diagnostics and include-path behavior.

Adoption history

asm-lsp is packaged for Rust users through cargo and for system package users through Homebrew and Nix according to the input package facts. GitHub metadata shows several hundred stars, which is meaningful for a specialized editor backend for assembly.

How it is used

Users install it with cargo, GitHub release binaries, or a package manager, then configure an editor LSP client to launch `asm-lsp` for assembly filetypes. Projects can add `.asm-lsp.toml`, or generate one interactively with `asm-lsp gen-config`, to select assembler dialects, instruction sets, diagnostics, and compiler settings.

Why package nerds care

asm-lsp matters to package nerds because it turns a historically editor-specific assembly tooling problem into a single reusable server binary. It is also a good example of a modern Rust CLI that becomes useful only when package managers, editor integrations, and per-project config all line up.
