NASM Language Support

Language features for NASM Assembly.

Features

This extension provides syntax highlighting and diagnostics for assembly files (.asm, .nasm, .s). It can use your system's nasm executable to detect compile-time errors and warnings such as invalid syntax or likely incorrect code. It also features auto-indenting to make your code easier to understand.

Requirements

While syntax highlighting can always be used, you must have a nasm binary in your PATH to view code diagnostics.

Getting a NASM binary on Unix-like systems

Your operating system might have a nasm package.

For example:

• macOS (Homebrew): brew install nasm
• Arch Linux: pacman -S nasm
• Debian/Ubuntu: apt-get install nasm
• Fedora/RPM-based: dnf install nasm, yum install nasm

Downloading a NASM binary

You can also download NASM from their website. Find a link to the latest version and download the binary for your platform. Then, add it to a folder that's in your path, like /usr/local/bin.

Extension Setting

This extension contributes the following settings:

• nasm.validate: If enabled, NASM Language Support will validate your assembly files. This is dependent on you having a nasm executable in your PATH.
• nasm.outputFormat: Changes the executable output format to assemble for. This is neccesary to provide correct errors based on your build target.
• nasm.reportWarnings: If disabled, validation warnings will be hidden during validation.
• nasm.extraFlags: Extra flags (for example, -w+all) that will be added add to nasm when validating assembly files
