I want to record audio with AudioKit. What I want to achieve is a buffer with 512 bytes if the buffer is full. It will translate the buffer info through TCP. And the current situation is that I only know how to restore the Audio data into a file like in the code below.
Can anyone provide some tips to achieve my goal?
Here is my code:
AKAudioFile.cleanTempDirectory()
AKSettings.bufferLength = .medium
do {
try AKSettings.setSession(category: .playAndRecord, with: .allowBluetoothA2DP)
} catch {
AKLog("Could not set session category.")
}
AKSettings.defaultToSpeaker = true
micMixer = AKMixer(mic)
micBooster = AKBooster(micMixer)
micBooster.gain = 0
recorder = try?AKNodeRecorder.init(node: micMixer)
if let file = recorder.audioFile {
print(file.directoryPath)
player = AKPlayer(audioFile: file)
}
player.isLooping = true
moogLadder = AKMoogLadder(player)
mainMixer = AKMixer(moogLadder, micBooster)
AudioKit.output = mainMixer
let clipRecoder = AKClipRecorder(node: mainMixer)
do {
try AudioKit.start()
} catch {
AKLog("AudioKit did not start!")
}
try! recorder.record()

Having a very difficult time trying to run command line arguments through Swift. I need to run commands on SQL files that a user manually drags onto the app (so the file path is different every time).
The piping between my app and the command line is working (sending 'pwd' will return the correct response), but when I try sending the arguments I want I cannot get them to work. I have tried using both "bin/bash" and "usr/bin/env" to no avail.
Essentially I am trying to rebuild a database that has been corrupted, without having to go in through terminal and do it myself. Common errors I see across attempts include 'Launch path not accessible' or 'File or directory not found'. I have tried using 'chmod 6' through terminal to set the permissions on the file, but this still does not work. Any help on what I am doing wrong to access the file, or another way to try and rebuild a database, would be greatly appreciated.
func checkForCorruption(filePath: URL) -> (String?, Bool){
let folder = filePath.deletingLastPathComponent()
let arguments = ["cd \(folder.relativePath)", "sqlite3 Restaurant.sql", ".mode insert",".output dump.sql",".dump", ".exit"]
let task = Process()
task.launchPath = "bin/bash/"
task.arguments = arguments
let inPipe = Pipe()
task.standardInput = inPipe
let pipe = Pipe()
task.standardOutput = pipe
let errPipe = Pipe()
task.standardError = errPipe
var output : [String] = []
task.launch()
task.waitUntilExit()
let data = pipe.fileHandleForReading.readDataToEndOfFile()
let errData = errPipe.fileHandleForReading.readDataToEndOfFile()
if let out = NSString(data: data, encoding: String.Encoding.utf8.rawValue){
print(out)
}
if let errOut = NSString(data: errData, encoding: String.Encoding.utf8.rawValue){
print("error: \(errOut)")
}
let outHandle = pipe.fileHandleForReading
if var string = String(data: data, encoding: .utf8) {
string = string.trimmingCharacters(in: .newlines)
output = string.components(separatedBy: "\n")
do {
try string.write(toFile: "\(folder.relativePath)/dump.sql", atomically: true, encoding: String.Encoding.utf8)
}
catch _ {
print("something went wrong")
}
}
outHandle.readabilityHandler = { pipe in
print("reading")
if let line = String(data: pipe.availableData, encoding: String.Encoding.utf8) {
print("New ouput: \(line)")
} else {
print("Error decoding data: \(pipe.availableData)")
}
}
return ("", false)
}
I got some help at work, for anyone struggling with this, here is the answer (the print statement is just were the dump file is located).
let arguments = ["\(filePath.relativePath)", ".mode insert",".output dump.sql",".dump", ".exit"]
let task = Process()
task.launchPath = "/usr/bin/sqlite3"
print(FileManager.default.currentDirectoryPath)
I have found some suggestions on how to add a block to a page, but can't get it to work the way I want, so perhaps someone can help out.
What I want to do is to have a scheduled job that reads through a file, creating new pages with a certain pagetype and in the new page adding some blocks to a content property. The blocks fields will be updated with data from the file that is read.
I have the following code in the scheduled job, but it fails at
repo.Save((IContent) newBlock, SaveAction.Publish);
giving the error
The page name must contain at least one visible character.
This is my code:
public override string Execute()
{
//Call OnStatusChanged to periodically notify progress of job for manually started jobs
OnStatusChanged(String.Format("Starting execution of {0}", this.GetType()));
//Create Person page
PageReference parent = PageReference.StartPage;
//IContentRepository contentRepository = EPiServer.ServiceLocation.ServiceLocator.Current.GetInstance<IContentRepository>();
//IContentTypeRepository contentTypeRepository = EPiServer.ServiceLocation.ServiceLocator.Current.GetInstance<IContentTypeRepository>();
//var repository = EPiServer.ServiceLocation.ServiceLocator.Current.GetInstance<IContentRepository>();
//var slaegtPage = repository.GetDefault<SlaegtPage>(ContentReference.StartPage);
IContentRepository contentRepository = EPiServer.ServiceLocation.ServiceLocator.Current.GetInstance<IContentRepository>();
IContentTypeRepository contentTypeRepository = EPiServer.ServiceLocation.ServiceLocator.Current.GetInstance<IContentTypeRepository>();
SlaegtPage slaegtPage = contentRepository.GetDefault<SlaegtPage>(parent, contentTypeRepository.Load("SlaegtPage").ID);
if (slaegtPage.MainContentArea == null) {
slaegtPage.MainContentArea = new ContentArea();
}
slaegtPage.PageName = "001 Kim";
//Create block
var repo = ServiceLocator.Current.GetInstance<IContentRepository>();
var newBlock = repo.GetDefault<SlaegtPersonBlock1>(ContentReference.GlobalBlockFolder);
newBlock.PersonId = "001";
newBlock.PersonName = "Kim";
newBlock.PersonBirthdate = "01 jan 1901";
repo.Save((IContent) newBlock, SaveAction.Publish);
//Add block
slaegtPage.MainContentArea.Items.Add(new ContentAreaItem
{
ContentLink = ((IContent) newBlock).ContentLink
});
slaegtPage.URLSegment = UrlSegment.CreateUrlSegment(slaegtPage);
contentRepository.Save(slaegtPage, EPiServer.DataAccess.SaveAction.Publish);
_stopSignaled = true;
//For long running jobs periodically check if stop is signaled and if so stop execution
if (_stopSignaled) {
return "Stop of job was called";
}
return "Change to message that describes outcome of execution";
}
You can set the Name by
((IContent) newBlock).Name = "MyName";
I'd folow the example From I200 pdf for a stock item, but I dont' know how to download the file from an Sales Order. Does anybody has a clue?
IN202500Content stockItemSchema = context.IN202500GetSchema();
var commands = new Command[]
{
new Value
{
Value = "AAMACHINE1",
LinkedCommand = stockItemSchema.StockItemSummary.InventoryID
},
new Value
{
FieldName = "T2MCRO.jpg",
LinkedCommand =
stockItemSchema.StockItemSummary.ServiceCommands.Attachment
}
};
var stockItemAttachment =
context.IN202500Export(commands, null, 1, false, true);
You were almost there, in the "stockItemAttachment" variable you should have the content of the file "T2MCRO.jpg" in byte format.
The only thing you have left to do is to write it to your file system.
You can use the following command :
File.WriteAllBytes(Path, Convert.FromBase64String(stockItemAttachment[0][0]));
I am writing nginx module which construct nginx chain then write this chain buffer to nginx temporary file to use it later (just after write happen). I've been searching every page and the only solution come up is the one bellow:
// Create temp file to test
ngx_temp_file_t *tf;
tf = ngx_pcalloc(r->pool, sizeof (ngx_temp_file_t));
if (tf == NULL) {
return NGX_HTTP_INTERNAL_SERVER_ERROR;
}
tf->file.fd = NGX_INVALID_FILE;
tf->file.log = nlog;
tf->path = clcf->client_body_temp_path;
tf->pool = r->pool;
tf->log_level = r->request_body_file_log_level;
tf->persistent = r->request_body_in_persistent_file;
tf->clean = r->request_body_in_clean_file;
// if (r->request_body_file_group_access) {
// tf->access = 0660;
// }
if (ngx_create_temp_file(&tf->file, tf->path, tf->pool, tf->persistent, tf->clean, tf->access) != NGX_OK) {
return NGX_HTTP_INTERNAL_SERVER_ERROR;
}
if (ngx_write_chain_to_temp_file(tf, bucket->first) == NGX_ERROR) {
return NGX_HTTP_INTERNAL_SERVER_ERROR;
}
This code does not return NGX_ERROR, is this meant nginx successful write temporary file into client_body_temporay_path? It the answer is yes, after that, I use fopen to open file, the file is not exist?
Can anyone please give me the right solution to handle ngx_write_chain_to_temp_file?
I find myself the solution
ngx_temp_file_t *tf;
tf = ngx_pcalloc(r->pool, sizeof (ngx_temp_file_t));
tf->file.fd = NGX_INVALID_FILE;
tf->file.log = nlog;
tf->path = clcf->client_body_temp_path;
tf->pool = r->pool;
tf->persistent = 1;
rc = ngx_create_temp_file(&tf->file, tf->path, tf->pool, tf->persistent, tf->clean, tf->access);
//ngx_write_chain_to_file(&tf->file, bucket->first, bucket->content_length, r->pool);
ngx_write_chain_to_temp_file(tf, bucket->first);
The only thing I cannot understand is if I set tf->persistentto false (0), after the file created, I cannot read from it even if I've not passed response to output_filter yet.
For Actionscript 2.0
Let's say this page
www.example.com/mypage
returns some html that I want to parse in Actionscript.
How do i call this page from Actionscript while getting back the response in a string variable?
use LoadVars():
var lv = new LoadVars();
//if you want to pass some variables, then:
lv.var1 = "BUTTON";
lv.var2 = "1";
lv.sendAndLoad("http://www.example.com/mypage.html", lv, "POST");
lv.onLoad = loadedDotNetVars;
function loadedDotNetVars(success)
{
if(success)
{
// operation was a success
trace(lv.varnameGotFromPage)
}
else
{
// operation failed
}
}
//if you dont want to send data, just get from it, then use just lv.Load(...) instead of sendAndLoad(...)
I understand. Use this code then:
docXML = new XML(msg);
XMLDrop = docXML.childNodes;
XMLSubDrop = XMLDrop[0].childNodes;
_root.rem_x = (parseInt(XMLSubDrop[0].firstChild));
_root.rem_y = (parseInt(XMLSubDrop[1].firstChild));
_root.rem_name = (XMLSubDrop[2].firstChild);
var htmlFetcher:LoadVars = new LoadVars();
htmlFetcher.onData = function(thedata) {
trace(thedata); //thedata is the html code
};
Use:
htmlFetcher.load("http://www.example.com/mypage");
to call.
I suppose you could use:
page = getURL("www.example.com/mypage.html");
And it would load the page contents on the page variable.
