Misleading error message when appending queries #414
Description
I am using trurl to append fields to a query to avoid url encoding them.
From the reading the man page, not paying enough attention and misinterpreting Long options can be provided either as --flag argument or as --flag=argument and -a, --append [component]=[data], I ran
trurl --url http://localhost:8000 --append query foo=bar
and got the error
trurl error: --append unsupported component: query
While the examples in the docs do use query=key=value, it threw me when it said query wasn't supported. Could the error be something like component query missing data or similar?
Thanks, and thanks for trurl in general, really helpful tool.

Perhaps there should be a hierarchy for some of the errors, where we ensure the flag is formatted properly, something like
--append expected '=' after 'query'and then if it knows its in the right form we can make judgements on whether it's supported or not.rajmodi8905 commentedon Oct 9, 2026
Hi, I’d like to take this on. I’ve reproduced the misleading message and prepared a small fix that reports a missing = before checking the append component, with regression tests. The available test suite and sanitizer checks pass locally. Please let me know if someone is already working on it.

Hi maintainers, the proposed diagnostic fix and regression tests are in #454. I'd appreciate a review when you have a moment, and I'm happy to make any changes needed. Thank you!
