Function to initialize new exercise

README.md

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).

bashrc.sh

#!/bin/bash

# Usage: new-exercise <slug> [<name>]
new-exercise() {
    DIR=~/Documents/personal/exercises/$1
    [ $# -eq 1 ] && TITLE=$1 || TITLE=$2

    [ ! -d "$DIR" ] || { echo "Exercise $1 already exists" && return; }

    mkdir -p $DIR \
    && cd $DIR \
    && echo "# $TITLE" > README.md \
    && touch .gitignore \
    && git init \
    && hg clone . $1 \
    && rm -rf .git \
    && mv $1/.hg .hg \
    && rm -rf $1 \
    && hg bookmark main \
    && code . \
    && cd -
}
