In TUI mode, no error messages are printed to stdout. This would would interfere with the UI drawing process. Instead, it the log will be written to a file called nixblitz.log in the working directory. This behavior is off by default.

The CLI uses cli-log to log to the file. To enable logging, the NIXBLITZ_LOG env variable must to be set.

A convenient way to set the env variable is to start the app as

• bash NIXBLITZ_LOG=debug nixblitz tui
• nushell $env.NIXBLITZ_LOG = debug; nixblitz tui

or, during development,

• bash NIXBLITZ_LOG=debug cargo run tui
• nushell $env.NIXBLITZ_LOG = debug; cargo run tui
