Description 

Author

This package can manage sets of code snippets stored in SQLite.

It provides a class and a simple application script that can perform several types of operations to store and retrieve code snippets using an SQLite database.

Currently, it can:

- Create an SQLite database table to store the snippets

- Perform searches for code snippets in the snippets' code, title, author, language, license, and tags, using regular searches or fuzzy searches

- Add, update, and delete snippets

- Get all snippets with the possibility to filter by language and tags

- Get a snippet by ID

- Get the count of all snippets stored in a database

Many developers have a set of code snippets that they frequently use in their projects.

Organizing those snippets in a way that is easy to find the snippet that you want to use in each project situation, is a challenge.

This package provides a solution to organize better collections of code snippets.

It provides an easy-to-use application that developers can use to manage collections of snippets with the possibility to search for snippets with names that may be misspelled and so tolerate typing mistakes.

        // fixed up listing rows a bit for the add section update
        // added some classes to db for json

        // one day I will have to get in to clean this beast, but today isn't that day. Neither is tomorrow.

        // v1.1 has a json export/import feature

        // currently broken: using not in the search field (and/or work)

        // added copy button to copy the code to the clipboard
        // added syntax highlighting and theme dropdown for syntax highlighting
        // added copy json button to copy the json to the clipboard
        // added cookie storing ability to remember the last used theme

        // created a cookie management javascript class for the ace.js code editor
        // created a jquery plugin to:
        // - handle the cookie management for combo boxes
        // - attach the ace.js code editor to the code textarea
        // - this was not fun :( but hey it works.
        // -- adds all sorts of cool ways to edit your code with syntax highlighting, error checking, autoindent, etc.

        // -- so using highlight.js for the listings and ace.js for the code editor. Note: only currently attached to update code section, but easy enough to add to add section which I will do if everything runs smooth in the update section, which I highly doubt, but hey, fingers crossed.
