working with strings
by Atte André Jensen 12 Jul '12

Hi Is it possible to split a string into an array of chars? Or work with parts of strings in other ways? src/util_string.h mentions these string related functions: std::string itoa( t_CKINT val ); std::string ftoa( t_CKFLOAT val, t_CKUINT precision ); std::string tolower( const std::string & val ); std::string toupper( const std::string & val ); std::string trim( const std::string & val ); std::string ltrim( const std::string & val ); std::string rtrim( const std::string & val ); I couldn't find some of them (like ltrim) in the manual, although they were mentioned in examples. Shouldn't they be mentioned in the manual? -- Atte http://atte.dk http://modlys.dk

Getting the status of running shreds *into* chuck
by Atte André Jensen 09 Jul '12

Hi I'm working on my chuck live setup again, and have a question I'm fairly sure I asked a (long) while ago: Is it possible to get the status of the VM inside a piece of chuck code? Machine.status() does the same as chuck --status, which is printing the info I need, but unfortunately to a terminal outside of chuck. The thing is, I'm sporking a lot of files from my code, and I need to keep track of which of them are still running at certain points... If this is not directly possible, does anyone have an idea for a hack? If anything else fails I think I might roll up my sleeves and hack in the chuck source, but that the last resort, since I'm not really speaking C++ that fluently... -- Atte http://atte.dk http://modlys.dk

Hi, as an excercise I coded a well known piece. Maybe it would fit into ChucKing_Scores section of the Wiki page. Feel free to comment, criticize etc. Antanas

CPU performance and Jack
by Matt Bard 07 Jul '12

07 Jul '12

Hello all, So, I'm doing a bit of heavier crunching and was wondering what aspects of CPU performance are the most critical the JACK's DSP percentage? I've not been able to find a very clear answer and was wondering if this group might know? Does running the dual core version of JACK make more sense with a slightly slower processor, or is speed the real winner in this case? To clarify, I'm basically just heavily crunching incoming audio. Thanks for any insight! -Matt
