Adding Console on Compiled Plugin For Debugging

[sakorada]

Hi ! I tried to add Console to Compiled Plugin , but I couldn't find option in ContentType for floating-tile.
Is it it bug or missing some?

Yeah, the Console is not part of the codebase that is used for compiling the plugin, also all calls to Console.print() are removed.

With a little bit of extra work you could write a file logger using the new FileSystem API though.

@Christoph-Hart Oh Okay ,
Console.print() is real time debugging ,but I guess file logger is also work ;D
Thank you

@Christoph-Hart Should HISE has File.appendText() or File.appendString() then?

[Christoph Hart]

Nope, you can write that functionality in HiseScript:

/** A asynchronous file logger.

    You can use this in order to log to a file. It replaces
    Console.print and appends anything to a file on the desktop.
    
    The actual file writing is deferred to a timer callback,
    so you can use it in realtime callbacks without too much
    overhead. It handles multithreaded access gracefully, however
    you can opt to deactivate this in order to trade in CPU spikes
    vs. logging accuracy.
    
    CAUTION: Never ever leave it enabled in a real project as 
    it will still allocate memory for storing the pending message
    queue.

@Christoph-Hart Wow , Thank you.
I will add this to my project now ,
