Re: CaSe-IndepeDent Menu SEARches?

Hi Ralph,

We use epicsdbbuilder to create and verify databases from Python, which I guess is similar:

https://github.com/Araneidae/epicsdbbuilder

(I'm about to package it in PyPI so that it's just a pip install away)

The dbVerify function in dbCore or dbStaticHost that it relies on disappeared for a while (in 3.16 maybe?) but appears to be back now.

Thanks,

Tom

In the good old times,

we used to have a static DB parser that was used to provide a "lint" tool for databases. (My mourning of the loss of that feature was largely ignored.)

In such a tool, I would support and encourage all kinds of intelligent hints for improving databases, showing similar options for typos being the simplest example.

(What about "Engineers that used the calcout record also often use the seq and compress records.")

"Fixing" bugs on the fly? Rather not. Large blocks of explanations and suggestions on the IOC console? Rather not.

Cheers,
~Ralph

Thar is sad to hear - but who hasn’t been there ?
Doesn’t the database loader give a useful warning/error ?
What is the difference between “to”, “fo”, “io”, “tu” ?
They are all typos, spelling errors.
What is the “real name” ? “To” or “to” ?
My suggestion would be to use a (naming) convention here - the same problem hits me all the time.
“CamelCase" or “snake_case" or “UPPERCASE" or “lowercase”  ?
None of my compilers is intelligent to figure out how to fix this typos - and that is a good thing.

And: Helping colegues to find this kind of bugs puts people together.
Exchange knowledge, chat about other stuff.
Best practise, new projects, problems, even the solved ones.

The first pass should still use strcmp() in case some IOC has choices (in mbbo strings) that only differ by case, but the second pass would accept the first to match even when the cases differ.
