Any way to break up long lines in SPIN2 & Fastspin?

rogloh

In a few places I have some longer source code lines in my driver I'd like to break up.

In C you can make use of a backslash for doing this, is there any way to spread code over multiple lines in Spin2/Fastspin?

Maybe you can end top line with "/*" and start next one with "*/" ?
I think that works for things in CON section anyway...

There was another trick too, but don't remember...

Yeah I vaguely thought there was a way too but maybe I'm wrong.

Just tried but the "/*" thing doesn't work in the PUB section. However I tried line wrapping with { ending one line and starting with } on the next line and that did work in Fastspin. It's a slightly weird way to do it, but I guess it might help if it is compatible with official SPIN2 as well.

    if (r := writeReg(addr, $555, $AA)) OR (r := writeReg(addr, $2AA, $55)) OR {
}      (r := writeReg(addr, $555, $80)) OR (r := writeReg(addr, $555, $AA)) OR {
}      (r := writeReg(addr, $2AA, $55)) OR (r := writeReg(addr, sa, cmd))
        return r

Right! I was thinking C++ for some reason... Sometimes I get the two mixed up

I don't know if it works in FastSpin, but you can use curly braces to break lines in Spin and Spin2. I have used this when I have a lot of locals.

pub some_method(param1, param2, param3) : result | {
}     local1, local2, local3

Thanks JonnyMac. I have just tried this myself too several minutes ago and it does work in PNut's SPIN2 as well as Fastspin so I will certainly start to use it in my drivers where needed. I am trying to make the same code work across both tools and it looks like I am getting there now.
