+This is a modern remake of my “Error Message Generator” that was originally written using Perl/Tk around 2006. This one is written in Go in 2023 using the Fyne UI and aims to match and surpass the features of the original Perl version.
+
+The original inspiration for this back in 2006 was an online web tool called “Atom Smasher’s Error Message Generator” which generated images of error messages. My Perl ErrorGen program included all of the Atom Smasher icons. Atom Smasher’s page seems offline recently, so interest has skyrocketed for my Perl ErrorGen program, so I decided to dust it off, redo it in Go and make it better than ever before.
+This program has two operating modes:
+The current features include:
+--cancel value can be printed to standard out if the user X’s out of the window without selecting a button.The roadmap of future features include:
+You can call this program from batch files or shell scripts to prompt the user with a graphical dialog box and read the button they chose from this program’s standard output.
+For example, from a bash script:
+#!/bin/bash
+answer=`./errorgen --alert --title "Disk Failure" \
+ --text "Failure to read from drive Z:/" \
+ --icon defrag --button Abort --button Retry --button Fail \
+ --default 1 --cancel Fail`
+echo "You have chosen: $answer"
+The full documentation is included below. Running errorgen --help from a text terminal will have the program print its documentation to you, but this won’t work on the Windows version since a program must decide if it’s a graphical or a command line app and can’t be both.
These are all the icons that currently come with ErrorGen:

There is a GNU Makefile to make build commands easier to remember.
+make setup installs Go dependencies for this project.make or make build will produce the ./errorgen binary.make run runs the Go app locally for development and testing.]make clean removes the built binary.Cross compiling: install Docker and fyne-cross and run make release to produce the build. To install fyne-cross:
go install github.com/fyne-io/fyne-crossIn case of permission errors (Docker often needs run as root) you can try sudo running fyne-cross directly, e.g. to produce Windows amd64 and i386 builds a command like:
+# which fyne-cross to use your locally installed Go binary for the current user,
+# so that root doesn't need to also install fyne-cross and have a $PATH set up.
+sudo $(which fyne-cross) windows -arch=\*Icons from the Atom Smasher Error Message Generator.
