[racket-users] raco demod : '"cannot instantiate `racket/gui/base' a second time in the same process"

To all, I have a project that I'm trying to compile to a single bytecode file via (raco demod). I compile a module .rkt file which requires several library module .rkt files. One of these module .rkt files is a windowing library that call on #lang racket/gui. (raco demod) manages to flatten and

[racket-users] Source Code Level Flattener

To All, I recently encountered an issue while trying to demodularize my modules to create a single bytecode file. Apparently raco demod has issues with the racket gui code. Hence, I've created a source code level demodularizer. It basically reads the require statements in the source code and i

[racket-users] Strange behavior when writing to a file

To all, I've been recently working on a database and I've encountered strange behavior when I use "call-with-atomic-output-file" and "with-output-to-file". Attached is a sample piece of code. The correct contents of the SOAP file should be : *First-Name : John *Last-Name : Doe *Gender : male *Pho
