File Saver Service Extension for Nova

File Saver Service is meant to help automate post-save functionality.

The use case I'm using this for is related to prettier-eslint & prettier; but instead of using an extension to handle those types of tasks, I'm executing a shell script that does exactly what each project requires. There's a lot that can be done from one shell script to execute tasks across multiple projects.

Requirements:

1. Create this file /usr/local/bin/novascripts

2. Then change permissions to executable: chmod +x /usr/local/bin/novascripts

3. Run this command to edit that file in Nova: nova /usr/local/bin/novascripts

4. Add your script to that file ...

The extension will execute that script on every file saved.

In the example below, I'm restricting what happens to files ending with ".js" and I'm restricting that to a particular directory.

Example of novascripts file:

#!/bin/bash

## Functions

startsWithPrefixAndEndsWithSuffix() {
    local string="$1"
    local prefix="$2"
    local suffix="$3"

    if [[ "$string" == "$prefix"* && "$string" == *"$suffix" ]]; then
        return 0 # true
    else
        return 1 # false
    fi
}

## Processing

if [ $# -eq 0 ]; then

    echo "No files passed as arguments to this script"
    exit 1

else

    # Just for site project #1
    siteProject1="/Users/johnnyappleseed/Documents/site-project"
    js=".js"

    if startsWithPrefixAndEndsWithSuffix "$1" "$siteProject1" "$js"; then
        cd $siteProject1
        yarn prettier-eslint --write $1
    fi
fi

Extension Installation:

1. Open Nova.
2. Choose menu Extensions > Extension Library...
3. Search extension FileSaverService
4. Click Install.

Usage:

Saving files automatically calls the shell script above.

The less "work" in that script, the faster it will execute, the example above table under a second -- which seems ok.
