sprintf issues

[porres]

• Update the help file

• Revise the code...

For whatever '%' argument we create in max, it generates an inlet, no matter if it's a valid thing - that's not the case in Pd, where it verifies if it's a 'valid' argument. So it should get whatever it receives instead of doing this checking.

BTW, the code has this:

/* CHECKED: max creates as many inlets, as there are %-signs, no matter
if they are valid, or not -- if not, it prints ``can't convert'' errors
for any input... */

And here's a list of issues:

The test patch

sprintf-test.pd.zip

[porres]

With 8e56237 I was able to remove the %a and %A options from cyclone and include %p

with 737fb0a I seem to have enabled "hi" and "hu"

with 9bc4a57 I'm now able to load %F

with d3c835a I'm now able to use "%lf" and "%lF"

sprintf-test.pd.zip

With e341338 I tried adding new formats that start with "%L", like "%Lf", etc. It only did work to prevent errors, but "%Lf" and "%LF" actually blow up PD, and the others just output zero... hence, I commented it out.

These seem to be a bit buggy in Max, but with Pd 64 bits around the corner, I think long integers/float could be useful in Pd ;)

this is wrong! It doesn't go over 2ˆ63

I updated the help file with 71af21a

Here's a review of which issues we still have:

• generate inlet for whatever '%' argument is created (or maybe not) - Pd only creates for 'valid' patterns and prints errors when it isn't.

• I couldn't include long double patterns (%lf, %lE, etc). %Lf" and "%LF" blow up PD, and the others output zero.

• %lu is limited to 2ˆ63

• Patterns %hhi, %hhu, %lli and %llu are still missing.

Been getting weird freezes when using %c and scrolling with a number box input. Sometimes it freezes. This time it also came with a .tcl error (tested with 0.49-1 on macOS Mojave)

EDIT: Not seemingly happening in Pd 0.50-2

btw, we've also been discussing [makefilename] in vanilla pure-data/pure-data#549

• [sprintf %.2#x] blows up Pd - old bug

"#" doesn't work in Max

[porres]

"[sprintf]: slot skipped ('j' modifier not supported in a format pattern)" is not an error given in Max

[porres]

• remove %p that was included in 8e56237

[porres]

remove %p that was included in 8e56237

done with af9bfa0

I guess I'll reboot this issue, cause it became too messy
