Note-CLI

Markdown Indexing and Pcre Regular Expression Compatible Full Text Searching for Advanced Note Takers.

Quick Start

# indexing file
./note-cli.js --index --database notes.db.example --file notes.md.example

# searching for keywords by regular expression
./note-cli.js --search --database notes.db.example --header "python" --content "hello.?world" --hide-sql

# and you will get:
[
    {
        "id": 2,
        "header": "how to hello world in python",
        "content": "```py \n# how to hello world in python\n\nprint(\"hello world\")\n```\n\n",
        "entire_note": "# how to hello world in python\n\n```py \n# how to hello world in python\n\nprint(\"hello world\")\n```\n\n"
    }
]

Basic concept

There are great note taking tools over there, such as Evernote. But the reason I quit using Evernote was its poor searching capability (i.e. cannot search some special characters; cannot search with regular expression, of course) and also, lack of extensibility. That's where Note-CLI comes in.

I'm kind of person who likes to take a note on my favorite text editor (Atom editor, for my case). For note taking, I have a single Markdown format text file. In it, I do take notes about everything. Note-CLI does work for indexing chunks of Markdown content to a database file and enables you to search your Markdown notes with SQL query (and also regex).
