STDHTTP

STDHTTP is a Go application that provides an HTTP interface for standard streams. It allows redirecting stdout and stderr of running processes to specified HTTP endpoints and also manages the processes themselves using a built-in broker.

Features

• Redirect stdout and stderr to specified URLs via HTTP.
• Manage processes started with stdhttp run through commands like stdhttp list and stdhttp kill.
• Start a debug server to monitor and manage processes in debug mode.

Installation

You can download pre-built binaries for your operating system from the GitHub releases page.

Steps:

1. Go to the Releases page.
2. Download the appropriate archive for your OS:
   • For Linux: stdhttp-linux-amd64.tar.gz
   • For Windows: stdhttp-windows-amd64.tar.gz
3. Extract the archive:
   • For Linux:

     tar -xvf stdhttp-linux-amd64.tar.gz

   • For Windows, extract the ZIP using your preferred tool (e.g., WinRAR, 7-Zip or built-in Windows Explorer functionality).
4. After extracting, you should have the following binaries:
   • Linux: stdhttp
   • Windows: stdhttp.exe and stdhttpd.exe
5. (Optional) Move the binary to a directory in your $PATH:
   • For Linux:

     sudo mv stdhttp /usr/local/bin/

   • For Windows, add the binary path to your system environment variables.

Usage

The STDHTTP application has three main commands: run, broker, and debug.

Running a command with stdout and stderr redirected to HTTP

You can redirect the standard streams stdout and stderr of a command to specified HTTP URLs using the --stdout-url and --stderr-url options:

stdhttp run --stdout-url URL --stderr-url URL COMMAND [ARG ...]

Example:

stdhttp run --stdout-url http://localhost:8080/stdout --stderr-url http://localhost:8080/stderr ls -la

Managing processes via the broker

If you start the broker with the stdhttp broker command, you can monitor and manage the processes you run:

Start the broker:

stdhttp broker

List active processes (wait for a 10 seconds after starting the broker):

stdhttp list

Run a command:

stdhttp run COMMAND [ARG ...]

Kill a process by its PID or kill processes by a pattern:

stdhttp kill {PID|PATTERN}

If broker goes down, you can restart it with the stdhttp broker command. Also if you want to see the broker in the list of processes, you can run it with stdhttp run command:

stdhttp run stdhttp broker

Or you can run the broker in the background:

stdhttpd run stdhttp broker

Debug Mode

You can also start a debug server to track requests in debug mode. To do this, use the command:

stdhttp debug

Once the debug server is running, you can run commands with the --debug flag to send requests to the debug server:

stdhttp run --debug COMMAND [ARG ...]

Background Mode

You can run stdhttp in the background on both Linux and Windows.

Linux

To run stdhttp in the background on Linux, you can use the & symbol after the command.

Example:

stdhttp run --stdout-url http://localhost:8080/stdout --stderr-url http://localhost:8080/stderr COMMAND [ARG ...] &

You can also use standard tools like nohup or screen for more advanced background management if needed.

Windows

On Windows, to run stdhttp in background mode, you should use the stdhttpd.exe binary instead of stdhttp.exe. This daemon version (stdhttpd.exe) will run the process in the background without holding up the terminal.

Example:

stdhttpd.exe run --stdout-url http://localhost:8080/stdout --stderr-url http://localhost:8080/stderr COMMAND [ARG ...]

This allows you to start processes and redirect their output without occupying the terminal window.

Configuration

STDHTTP uses options and environment variables for configuration. For more details, run stdhttp --help.
