Use correct field separator in keywords.txt

[per1234]

The Arduino IDE requires the use of a single true tab separator between the keyword name and identifier. When spaces are used rather than a true tab, the keyword is not highlighted.

Thanks for the advice @per1234, but I have a question: Is this file totally required?

If not, I'll delete it instead of fixing it. I'm totally against using a "looks the same" symbols with sooo many attached historical problems, like the "tab" is.

You made me realize that I'm already using it in this file, and I'll not keep it anymore.

Are "space" allowed inside any of the keywords? If not, then why the need of using a Tab? Makes no sense

In any case, if it is needed, please change your branch name to "hotfix/your-original-name" as I'm using Git Flow, and a direct master commit is not the way to go.

Thanks for the advice and thanks for being so nice this and other issues, as I remember you. Sorry if I appear rude but I really REALLY disagree to be on 2019 and this "Tab" thing keeps being a issue.

If the "separator" is a problem, there is more CSV-like approachs than using an invisible symbol that makes things break without even notice it.

My respects to you, and my super anti respect to Tab symbols :D

I will wait your answer before actually editing(deleting) the keyword file.

Thanks

Is this file totally required?

No. It's completely optional. keywords.txt is used to color library keywords in the Arduino IDE. Quite a few 3rd party library authors don't bother with creating and maintaining a keywords.txt. It is fairly common for beginners using these libraries to think something is wrong when the function names, etc. don't color as they have come to expect from using the official Arduino libraries.

why the need of using a Tab?

Some efforts were made to allow any the use of spaces as a separator but it ended up being quite difficult to accomplish and the effort was abandoned:
arduino/Arduino#6693

I would like to see more flexibility in keywords.txt parsing because the use of spaces or multiple tabs as a field separator by 3rd party library authors is a very common problem. I also don't feel that the requirement to use a single true tab field separator is so onerous. The only time keywords.txt is edited is when there is a change to the API so it really doesn't impose much of a burden so I'm happy to work within the constraints of the existing system.

I totally understand your position, and again, thanks a lot for your time and support, as my behaviour is nothing against you or your work, which I find extremely invaluable.

Big regards
