k_cext PD external
INTRODUCTION
The k_cext PD external makes you able to program the programming language "C" directly within the PD objects.
+-------------------------------------------------------+ | Which means: You don't need an external text-editor. | +-------------------------------------------------------+
WHY USE K_CEXT
First, the reason for using "C", and not some other programming or scripting language, was simply because it is so easy to compile and link c code inside externals in pd. Because C is probably not the best suited language for this task, except when extreme cpu-efficiency is needed.
Still, I personally think making small k_cext objects is a lot more comfortable than making large pd sub-patches doing the same things. And thats probably the main reason to use k_cext.
A SMALL EXAMPLE IN K_CEXT
The following k_cext object have one inlet and one outlet. What it does, when receiving a value on the inlet, is to send the _previously_ received inlet value to the outlet.
[ k_cext 1 1; static t_float prev=0; O(0,prev); prev=V(0); ]
The "k_cext 1 1" line is the k_cext header. The first "1" means that it has one inlet, and the second "1" means that it has one outlet.
The "static t_float prev=0;" line declares a variable for the object called "prev". "t_float" means that the type of the variable is a floating-point number. "static" means here that the value for the variable is remembered the next time the object is runned, which is necesarry if we want to send out the previous value sent to the inlet.
"O(0,prev);" sends the value of "prev" to outlet number 0. "O" is a function.
"prev=V(0);" stores the value of the current inlet to the variable "prev" for the next time the object is run.
THE SAME EXAMPLE AS A PD SUB-PATCH
The following PD-patch does the same:
[inlet] | [t f b] \ / \ / X / \ / \ [float] | [outlet]
I guess its a matter of personal taste, but I really don't find the PD-way of sending out a previous value very intuitive.
And the advantage of using k_cext instead of making PD sub-patches becomes more appearent the larger the tasks are. Look at the help-file, and try to do the same things directly in PD.
K_CEXT OBJECT
A k_cext object can be divided into three parts:
1. Header. 2. Variables 3. Body.
K_CEXT HEADER
The first line in a k_cext header is built up like this:
"k_cext <num_inlets> <num_outlets> <default inlet values>".
"k_cext 4 5 1 2 3 4" means that the object has 4 inlets, 5 outlets, and the value of V(0) is by default 1, the value of V(1) is by default 2, the value of V(2) is by default 3, and the value of V(3) is by default 4.
Its optional whether you want to set "default inlet values" or not. If not set, they get the value 0.
K_CEXT VARIABLES
There are four types of variables that makes sense using in a k_cext object. These are:
"int" - integer number. "t_float" - floating point numbers. "INTARRAY" - An array of integer numbers. "FLOATARRAY" - An array of floating point numbers.
See the help patch for examples of use.
MACROS / USING THE PD OBJECT AS A TEXT-EDITOR
Using the pd object as a text-editor is unfortunately a bit limited. But by using some pre-defined macros spesified in the "k_cext.h" file, its not that bad.
begin/end - The most noticable limitation is probably that you are not able to write { or }. This is solved by using the BEGIN and END macros. Or better; the "DO" symbol which makes k_cext automaticly insert BEGIN and END for you. Look at the help-do.pd patch.
lineshift - The pd object text editor doesn't understand lineshift directly. Instead you have to use ";" at the end of each line.
semicolon - If you need to write ";", but dont want the line to end right there, use the "SC" macro instead.
indentation - The pd object text editor automaticly removes spaces and tabs from the beginning of lines. You can work around this by writing ". " instead. The k_cext external removes all ". "'s at the beginning of lines before compiling the code.
More macros are defined in the k_cext.h header file.
OS k_cext runs fine in linux using gcc and in windows using visual C. The macosx code was made by looking at code inside PD, and has never been tested (at least not that I know if). It might work, but probably not. Check out the k_cext_macosx.c file.
FAQ Q: I can not get k_cext to work in windows, and I dont have Visual C. A: You need Visual C.
Q: Where can I get a windows .dll file? A: Since you allready need to have some basic knowledge about C, in addition to a C compiler, it should not be that hard for you to compile the .dll file yourself, if you know how to use the k_cext external. So you have to make it yourself.
CHANGES 0.3.0 -> 0.3.1: -Works with VisualC. (0.3.0 didn't): -Workaround for missing variable number of argument macros in VisualC, (which is not a gcc extension, by the way, but a part of the iso99 c-standard). -Workaround for missing stdbool.h file in VisualC. (also a part of the iso99 c-standard) (code by Thomas Grill) -Workaround for missing static <something> <something>[] in VisualC. -Fixed a variable which was not defined at the beginning of the function. (Thomas Grill)
0.2.5 -> 0.3.0: -Added the k_cfunc object. k_cfunc is very similar to k_cext, but instead of being triggered by getting a bang or value on the first inlet, the k_cfunc-code is run when being called from another k_cfunc object or a k_cext object. In other words, its a c function object available for k_cext.
0.2.4 -> 0.2.5: -Fixed the problem that integer numbers sometimes was converted to floats before compiling. -Fixed ENDSWITCH macro. -Small internal changes. -Changed the PD subpatch example in the README file to use the trigger object. The information that was written earlier that you had to make connections in a certain order, was misinformation. The behaviour is unspesified according to the spesification. The trigger object fix such situations. (But if you need to use the trigger-object, its a good sign that you should rather use k_cext for the operation anyway. My opinion.) -Removed the windows .dll file. If you are not able to compile up k_cext yourself, you most probably aren't able to use k_cext either. -Added a "print" message, which prints out the generated c-code with line-numbers to the terminal. -Prints out the generated c-code with linenumbers if compilation fails. Makes debugging a lot faster. -Added a SEND macro that takes a symbol string and a number, and sends a pd message. -Added "DO", which can (and should) be used instead of the BEGIN macro. DO is not a macro, but a special symbol used by the k_cext preprocessor to know when to automaticly insert BEGIN and END based on indentation. Just like Python. :) -Changed the main example patch to use DO instead of BEGIN/END. -Added some more example patches. -Fixed nearly correct indentation for the generated C code.
0.2.3 -> 0.2.4: -Added a lot of new macros to k_cext.h. -Fixed the help file a bit. -Wrote the README file. -Changed the license for k_cext.h from GPL to LGPL. (Note, the k_cext external is still GPL) -Some windows code was for some strange reason put in the macosx file. Fixed. -Added Mac OSX to the Makefile. (Not tested.)
