Research direction

Start by reviewing the Spring Shell logging configuration examples in the issue and the behavior of interactive versus non-interactive terminal output. The issue names no files, tests, or entry points, so the first step is to locate the existing logging and shell startup configuration. Done means agreeing on and implementing a defined approach for conditional debug logging, file logging, and startup errors without disrupting interactive output.

Written by the indexing model from the issue text.

Description

type/enhancement

Backround; logging is hard especially with cli apps where whole infrastructure is designed for server applications.

While logging should be relatively fine with plain command output it will completely mess up terminal if there is any interactive components relying terminal escape characters.

In normal shell app you want to disable console logging:

logging:
  pattern:
    console:

And possibly add debug logs to a shell temporarily:

logging:
  file:
    name: shell.log
  level:
    root: debug
    org:
      springframework:
        shell: debug

Trouble with this is that you never get any errors if a shell hard fails at startup.

We should come up with custom opinionated logging configuration so that:

  • User can conditionally enable debug logging
  • Can configure logging into file
  • Can have some automatic "magic" depending if command is interactive or non-interactive
  • Regarding if terminal should not have any logging into console, automatically write those into file

We'll keep this issue to collect ideas and other discussion to prepare a solution.
