[==~] [>~] etc.. objects in libpd for android
  • henrik.ekeushenrik.ekeus
    Hi,
    I've got to do some various bits of signal rate logic, but I can't use [expr~] for licensing reasons. I'm finding it hard to do as there are so few objects in vanilla (I'm building an android app).  I could do what I need to do if there were some basic logic objects such as [==~] and [<~].. but they don't seem to exist in vanilla!  Is there a way to include these and have them useable in the libpd for android?  <br />
    Many thanks,
      Henrik

    You could easily build your own externals for the sort of functionality you want, but did you know that expr~ is now covered by the LGPL? Chances are that you can use it now.

    Many thanks for the reply, that is interesting..

    With regards to expr~ in my PD window I get -

    "expr, expr~, fexpr~ version 0.4 under GNU General Public License".

    Is there a newer version? or is that print-out misleading? (i'm no lawyer, but should it not have the word 'lesser' somewhere? :)

    Yikes, I just noticed that the license document in the expr~ folder is the LGPL, but the code still refers to the GPL. I suggest you ask your question on the Pd or Pd-dev mailing list, to get a definitive answer.

    Yeah, if that's the case, we need to know. Hopefully it was just a matter ofmforgettingmtomupdatenthe source headers ...

    I've seen the license issue for expr~ mentioned a couple of times. Just to be clear- it's expr~ (the signal version with a tilde) and not the usual expr (no tilde) that has the licensing concern?
  • pbrinkmannpbrinkmann
    expr and expr~ are basically the same thing, so the license issue applies equally to both of them.
  • choonschoons
    wow so [expr 2 + 2] can cause licensing problems for an app? How could that ever have been allowed to happen? Do the arithmetic and relational operators like [+1], [> 1] have the same problem?
