In plain words
Docker Exec is a command-line tool that uses Docker images to run code in multiple programming languages without installing compilers or interpreters locally. Users simply execute the dexec command with their source file, and the tool automatically selects the appropriate Docker image based on the file extension to compile and run the code. It supports passing arguments to executed programs, making it useful for developers who want to test code across different languages without managing language-specific installations.

From the sources
Docker Exec is a collection of Docker images capable of executing code in many different programming languages without requiring a single compiler or script interpreter on your machine. The dexec command line interface provides a simple front end, picking the appropriate Docker image based on the source extension. Let's take a closer look at one of the examples, helloworld.cpp : # include < iostream > int main () { std::cout << " Hello, World! " << std::endl; return 0 ; } executing it is simple: $ dexec foo.cpp Hello, World! Docker Exec also supports passing arguments to the executing program, passing arguments to the compiler, mounting extra files and directories in the executing container…from docker-exec.github.io

Talanoa▲345Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
