Summary

  • jetdb export -d with an empty or longer value now prints jetdb: delimiter must be one character, got '<value>' and exits 1. It used to use , for an empty value and to warn and use the first character of a longer one, so -d "\t" in a shell gave output delimited by a backslash.
  • The check is in the CLI rather than a clap parser, so that the error has the jetdb: prefix and exit code 1 of the other errors.
  • The output with a one-character delimiter is unchanged. docs/cli.md and docs/cli.ja.md state the rule and give the tab example as -d $'\t' (bash and zsh).

…ecting it

- Make jetdb export -d with an empty or longer value fail with an error with the jetdb: prefix and exit 1
- It used to use , for an empty value, and to warn and use the first character of a longer one
- Test that an empty, a two-character and a shell "\t" (a backslash and t) delimiter are errors, and that a wide single character works
- State in docs/cli in English and Japanese that the delimiter is one character, and give the tab example as -d $'\t'
