While syntax highlighting can always be used, you must have a nasm
binary referenced in your PATH
environment variable to view code diagnostics.
Your operating system might have a nasm
package.
For example:
brew install nasm
[^1]pacman -S nasm
apt-get install nasm
dnf install nasm
, yum install nasm
You can also download NASM from their website. Find a link to the latest version and download the executable for your platform. Then, add it to a folder that's referenced in your PATH, such as /usr/local/bin
.
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, warnings will be supressed.nasm.extraFlags
: Extra flags (for example, -w+all
) that will be appended when running nasm
when validating assembly filesnasm.nasmPath
: The name or path of the nasm executable (e.g. /opt/homebrew/bin/nasm
, /usr/local/bin/nasm
)nasm.checkOnType
: If enabled, validates assembly files as you type rather than after saving.bb[^1]:
You may need to add set the nasm.nasmPath
option to /opt/homebrew/bin/nasm
for the extension to work properly.
