TabToChordPro

JavaScript module to convert regular tab files to the ChordPro format.

Installation and use

1. Add the TabToChordPro package to your project with npm:

   npm install tabtochordpro

2. Use require in the file where you would like to make use for it:

   const tabToChordPro = require('TabToChordpro')

3. There is only one method to use:

   tabToChordPro.tabToChordPro(tab, artist, title, capo, key, outputSong);

   Parameters:

   • tab (string): The contents of the tab file. For example a string that contains the following:

   Bm7                                 G      D/F#   Em   G   D/F#   Em
   In pitch dark I go walking in your landscape.
   Bm7                           G     D/F#   Em   G   D/F#   Em
   Broken branches trip me as I speak.
   

   • artist (string), title (string), capo (int), key (string): Metadata of the song. All of these may be null or undefined if you do not want them in your ChordPro file.

   • outputSong: This is the callback method wich will contain a parameter that will hold the output. For example, you could define a method to a variable to handle the output:

   const outputSong = (converted) => { console.log(converted) }

   Then pass this variable to the procedure as a parameter. If this callback procedure is not provided, this method will simply return a string containing the song in ChordPro format.

Simple example

const tabToChordPro = require('TabToChordpro')

let tab = `
    Bm7                                 G      D/F#   Em   G   D/F#   Em
In pitch dark I go walking in your landscape.
Bm7                           G     D/F#   Em   G   D/F#   Em
Broken branches trip me as I speak.`

console.log(tabToChordPro.tabToChordPro(tab))

Outputs:

In p[Bm7]itch dark I go walking in your lands[G]cape.[D/F#][Em][G][D/F#][Em]
[Bm7]Broken branches trip me as I s[G]peak.[D/F#][Em][G][D/F#][Em]
