I’ve made read key press function in PHP. The code sets non-block stream mode for STDIN and in while waits when STDIN will receive any data. It works, but I noticed that function loads CPU to 100%. How much is bad this code for CPU and is there any another way to check is STDIN contains any data?
I want to use Ghostscript command within PHP without writing the input or output in files.
I know PHP is usually used for web development, where there is no standard input, but PHP claims to be usable as a general-purpose scripting language, if you do follow it’s funky web-based conventions. I know that PHP prints to stdout (or whatever you want to call it) with print and echo, which is simple enough, but I’m wondering how a PHP script might get input from stdin (specifically with fgetc(), but any input function is good), or is this even possible?
I am trying to write a PHP script that uses the pdftk app to merge an XFDF with a PDF form and output the merged PDF to the user. According to the pdftk documentation, I can pass the form data in via stdin and have the PDF output to the stdout stream. The normal, file-not-stream way to use pdftk from the command line is:
I want to read a single character at-a-time from the command line in PHP, however it seems as though there is some kind of input buffering from somewhere preventing this.
Would anyone know when using python-shell if you can keep the python script running when its called from Javascript? Maybe call a method from a Python class from Javascript using python-shell?
Is it possible to listen for incoming keystrokes in a running nodejs script?
If I use process.openStdin() and listen to its 'data' event then the input is buffered until the next newline, like so:
I’m looking to process a text file with node using a command line call like:
I am trying to spawn an external process phantomjs using node’s child_process and then send information to that process after it was initialized, is that possible?
Is it possible to synchronously read from stdin in node.js? Because I’m writing a brainfuck to JavaScript compiler in JavaScript (just for fun). Brainfuck supports a read operation which needs to be implemented synchronously.
