Re: [PD] Solution for deleting files via pd?
Thank you all so much for the great answers :) Since I posed the question I have been working out a solution. In the attached file I first send a message to [shell] to tell me how many files are in the folder. Then, since all the files are named 1.wav, 2.wav, etc., I run those numbers through a [list-drip] and tell [shell] to delete them one at a time. It ALMOST works I think, but it has an error that says shell: old process still running... Maybe [list-drip]'s consecutive messages are too fast? Maybe there is no time between the first kind of [shell] command and the second? Also, I'm a Macbook Pro (4 GB ram) user running 10.7.5 Lion. I'd appreciate any help with my code. Like I said, I think I'm almost there, maybe my code needs a little tweaking. Thank you, Sebastian On Mon, Jan 28, 2013 at 7:24 AM, Lorenzo Sutton lorenzofsut...@gmail.comwrote: Hi.

A different strategy might also be to actually *not* delete files from within Pd, but outside, befor or after you close your patch. This is easily accoplished e.g. by a script. Also a suggestion would be to give the temporary files very eloquent names such as 'TEMP_FILE_TO_DELETE_0001.wav' etc. and (whichever way you decide to do it) delete specifically *those* files instead of e.g. the whole directory, so e.g. instead of: rm -f ./dir_to_delete/* something like rm -f ./dir_to_delete/TEMP_FILE_TO_**DELETE_*.wav' In my humble opinion it makes it more obvious what you want to delete, and (hopefully) less error/disaster prone (ok.. I've been bit by accidentally deleting files with no back up) Lorenzo.

[PD] Patch that creates messages with multiple elements?
Hi, How would I go about building something that takes a number, and creates a message with THAT many consecutive numbers in it, starting with 1? For example: When I receive the number 7, my machine creates a message that looks like [1 2 3 4 5 6 7(... or when I get 3 it creates [1 2 3( I would appreciate any thoughts on this.

[PD] Cursor automation in pd?
Hi everyone, I can't find the answer to this question anywhere. Is it possible to automate the movement and clicks of a mouse in pure data? Or maybe there is an easier way of doing what i'm trying to do? In my project, I am having pd sense a google talk phone call being made to my browser (Google Chrome). It will wait for one ring, then I'd like it to move the mouse and accept the call on the browser. One problem I see with this is that it might stop once it clicks out of the patch..? I know there are other automation programs out there; I was actually working on some code in AutoIt to accept that call. But i'd like to do it all in pd, if possible.

[PD] Text with bigger font?
Hi, I'd like to title sections of my patch (ex. Reverb, Levels, etc.) in bigger font. The only way I know to do this is by writing comments, then increasing the font size in the edit menu... but this increases ALL font sizes! Is there any way of creating text in my patch with bigger font without universally affecting font size?

[PD] Creating an Automatic Offset Adjuster
Hello, I'm creating a patch that will adjust the volume of an incoming signal. It is controlled by the Yaw of a wii remote connected to my laptop via bluetooth (OSCulator app), but i've found that the data from the remote's gyroscope is constantly changing. For example, i'll turn the remote so the yaw turns the volume up 100%, then i'll move it around, but when I come back to this same position the yaw/volume will be 75% up. To fix this I've created a subpatch that stores the raw Yaw data into an array and uses the min/max of that array to adjust the range of the yaw data controlling the volume. The problem is that i've set the array to write over itself after the 99th index... so the min/max values are only stored for a few seconds before being over-written. This auto-offset adjuster works great ONLY for those few seconds where the array isn't over-written. Does anyone know the best way of doing this? I've attached the subpatch. Its hot inlet is where i send my raw gyroscope data, the cold inlet is used to turn on/off the patch, and the outlet is the scaled data (between 0-1) which controls volume. Sorry for the long message, thank you for your time. -Sebastian -- Sebastian Ignacio Valenzuela Rojas Composer - Performer svalenzuelamusic.wix.com/home youtube.com/svalenzuelamusic http://www.youtube.com/svalenzuelamusic auto_offset.pd Description: Binary data ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] 2 color questions in GEM
Part of the function of a patch i'm working on requires the background color to change according to the first 8 numbers on my number pad. I've assigned a variety of different colors to the numbers 1-8, but i'm finding that 2 of them are yellow... when only one should be yellow and the other orange. I've been changing the color of [gemwin] to Orange by sending it a [color 255 165 0( message, but this still comes out as yellow. All my other colors (blue, green, black, white, red, purple, white) work fine. Any ideas? My second question: how do you change the color of text rendered in the [text2d] object? Does that have to do with changing the font? Its coming up as white, I'd just like to change it to black.

[PD] Highest and Lowest values of array?
I imagine this isn't very difficult to do, but i haven't been able to find it anywhere. I have controller data constantly begin written (and updated) into an array - What is the easiest way to extract the highest and lowest numbers from this array as these two variables change? I'm not looking for something that will constantly be giving me the value of those variables, but, for example, something that gives me the highest value once, and updates that number when it finds a new highest value.

[PD] [gemwin] - Storing window-shots and changing view?
Hi everyone, I have two big questions regarding the graphics object [gemwin]: How does one change the focus of the graphics window? For example, we are using a computer video camera to look at the surface of a pepperoni pizza (in real time), but i want to change the view so that all you see is one pepperoni slice in the graphics window (still a square window/image). Also, How does one go about temporarily storing an image/frame of the live video going through the graphics window object? For example, now that i have the piece of pepperoni in view, i want to capture ONLY this portion of the entire pizza/live video stream. I am new to [gemwin], but would like to implement it into an audio/video installation due next week. Any help would be greatly appreciated!

[PD] Detect a stagnate number
Hi everyone, When I was learning ChucK I remember being able to do this with boolean logic: Receive values from integer X. If X stays the same for a period of at least 1 second... (to end this sentence in Pure Data) I'd like to send a single bang. So I'd like to build something or find some object that watches a constantly changing number box and when it becomes stagnate (doesn't move from one number to the next) for a period of 1 second, I'd like to send a single bang.

[PD] Ignore initial impulse/bang
Hi, I would like an object or a construction of something that would ignore the first bang it receives. To be more descriptive, If something outputs a bang when it receives one, I would like it to output a bang the SECOND time it receives a bang. Also, if possible, I would like to reset this behavior.

[PD] Audio line circuit breaker?
Hi again, Can such a thing be built?
