Bash function for new exercises

I find myself frequently creating one-off repos to test a concept or technology. To streamline this process, I have written a bash function and included it in my bashrc configuration.

When invoked, it creates a new directory, creates a mercurial repository preconfigured for git integration with a main bookmark activated, creates a README.md file, and then opens the directory in my editor of choice (VSCode).

Bash Prompt

My current directory structure can result in lengthy directory paths, which can make for difficult bash prompts with Fedora's default prompt. To deal with this, I constructed a bash prompt that allows for lengthy directory paths without impacting where the cursor for the command begins.

PS1

# set prompt: <horizontal line>\n<green>user@hostname</green>:<cyan>current directory</cyan>\n<yellow>time</yellow> $
export PS1="\[\033[1;30m\]$(printf '─%.0s' {1..80})\n\[\033[0;32m\]\u@\h\[\033[0m\]:\[\033[0;36m\]\w\[\033[0m\]\n\[\033[0;33m\]\t\[\033[0m\] $ "
