* Missing documentation.
- units for basic things (online): for instance, what are the units for the methods of, say, Chorus? be good especially for newbies.
- LiSa and GenX doc, other than examples
- valueAt() for SndBuf is not listed on web doc
- New interfaces to the Hid device.
- Especially the differences between the KBHit and the Hid way of dealing with the keyboard turn out to lead to questions.
- General .op in UGens: On the forum Spencer noted;
All ugens have a .op parameter, which specifies how they deal with multiple inputs. the default is for the ugen to just add multiple inputs, but specifying 3 for .op will cause the ugen to multiply its inputs together. Since this happens "below the hood" so to speak its a lot better CPU-wise than multiplying in ChucK, with the added benefit of being updated every sample.
The manual only lists -1, 0 and 1 as options with he full range being being explained at the "Gain" ugen entry.
kijjaz tried applying various .op to some Ugens but multiplier, divider did not work. Trying on a Gain works well.
- The "this" keyword, similar to "me" except with regard to class-instances seems to be undocumented. Spencer explains here.
- Similarly: from some exchanges on the Forum around 14 Feb 2007: "there are a couple of references to "this" in the chuck manual. pages 31, 81. but no documentation of it's (or should i say this's) use."
Kassen replied: "I looked those up and you are right, but those references are a bit... erm.... thin (to say the least). It does make one wonder what "pure" does. The "pure" keyword gets mentioned on page 31 as well and that's the only reference to it. "const" is another mysterious word in that list." So in summary, we need some better explanations of "this", "new", "pure" and "const".
- Many of the examples referred to in the reference section as being in the /examples directory, (for example, osc.ck, pwm.ck, etc.) are no longer found there or in any subdirectories that I have been able to tell.
* Outdated info.
- From mailing list, original text by Tazumi and Spencer, dec8;
> i have got a question about sending strings with the osc class.. > ist this possible? > The manual says that the osc object has 2 member functions > (addInt / addFloat).. > so is there a way to send (or revieve) other data types?
It seems the manual is out of date in this regard, it is in fact possible to send strings in ChucK's OSC implementation. Just use an "s" for the type specifier and addString to supply the string. getString will retrieve the string on the listener end.
* Suggested clarifications
- Add new section on this page for manual/doc errata?
- Could somebody please go into what the word "new" means in ChucK, exactly? It's currently mentioned in the manual exactly once (in that sense). It creates a new instance of a object and it's somehow syntactically similar to "!" and that's about it as far as the manual is concerned.
- The section on getting MIDI input is reportedly hard to understand.
* Erroneous *
(some errors remaining 188.8.131.52 version) - p. 109 under Phasor: "as a phase control. see examples/sixty.ck for an example" I can't find any example with that name - p. 103 zerox.ck is actually under "examples/basic" - p. 102 still no info on HalfRect and FullRect - p. 110 code fragment under Blit really belongs to Impulse - p. 97 "float pi -(currently disabled - use pi)" -- is it just me, or does that make no sense? - p. 88 "generaters", "These are useful for debug ChucK..." - p. 86 formatting of chuck command line is sort of garbled in my PDF viewer. It probably would really be nice to format that box with a monospaced font (chuckles/2007 10 22) - p.115 (and others in this section?) at least BandedWG claims that parameters are in the range 0.0 - 1.0, but the example bandedwg2.ck (and an error message you can get) indicate that parameters mostly range from 0 to 128)
- The VM reference claims the syntax for requesting in&out channels is "--chan" or "-c", that first one should be "--channels", "chuck --help" does report the correct syntax.(Kas.)
