+title: VSCode Extension for lnav
+excerpt: Syntax highlighting for lnav scripts
+---
+
+I've published a simple [Visual Studio Code extension for lnav](
+https://marketplace.visualstudio.com/items?itemName=lnav.lnav)
+that adds syntax highlighting for scripts.  The following is a
+screenshot showing the `dhclient-summary.lnav` script that is
+builtin:
+
+![Screenshot of an lnav script](/assets/images/lnav-vscode-extension.png)
+
+The lnav commands, those prefixed with colons, are marked as
+keywords and the SQL blocks are treated as an embedded language
+and highlighted accordingly.
+
+If people find this useful, we can take it further and add
+support for running the current script/snippet in a new lnav
+process or even talking to an existing one.
