Checks top-level and basic syntax

Expression syntax

Beyond basic Kaitai Struct YAML (.ksy) syntax checking, checks your KSY expressions:

Tree & Hex View

Open a .ksy file and click the file icon in the editor toolbar (or run Kaitai: Open Hex Viewer) to open two side panels:

• Kaitai Hex — hex dump of the binary file.
• Kaitai Tree — parsed structure based on the active .ksy.

You can set a glob pattern to only display a subset of files (those that are relevant to the KSY at hand) for quick viewing.
