@ltftf/srt-parser-2 v2.0.0

srt-parser-2

An SRT parser for Javascript.

It reads an .srt file into an array.

This is a fork of srt-parser-2.

What's changed

• Removed the unnecessary class instantiation
• Text is parsed as an array of strings (by line) instead of a single string with \n characters

Install

npm

npm install @ltftf/srt-parser-2

or yarn

yarn add @ltftf/srt-parser-2

Example

This is an SRT format file:

1
00:00:11,544 --> 00:00:12,682
Hello
World

it would become:

[{
    id: "1",
    startTime: "00:00:11,544",
    startSeconds: 11.544,
    endTime: "00:00:12,682",
    endSeconds: 12.682,
    text: [ "Hello", "World" ]
}]

Environment support

Since it only process text,
it should work in both Browser and Node.js environment

Usage

let srt = `
1
00:00:11,544 --> 00:00:12,682
Hello
`;

import { fromSrt, toSrt } from "@ltftf/srt-parser-2";
var srtArray = fromSrt(srt);
console.log(srtArray);

// turn array back to SRT string.
var srtString = toSrt(srtArray);
console.log(srtString);

You can run this example using node example/1.Comma.js

CLI

npx srt-parser-2 -i input.srt -o output.json --minify

Why?

Why this one special? There are plenty of SRT parsers on npm:

• subtitles-parser
• subtitles-parser-vtt
• subtitle
• srt

What's wrong with them?

Nothing wrong.
All of them can handle this format:

1
00:00:11,544 --> 00:00:12,682
Hello

But I want to handle format like these:

00:00:11.544

This is wrong format, it use period as separator

Or this:

00:00:11,5440

This is also wrong format, millisecond has 4 digit (should be 3)

Or this:

1:00:11,5

Similar, hour & millisecond is only 1 digit (wrong)

Or this

00:00:00.05

etc

Format Support

Basic principle:

1. If hour,minute,second is shorter than 2 digit, pad start with "0", if longer than 2 digit, only save first 2 digit.
2. Millisecond is the same, but it's 3 digit.
3. Separator can be .(periods) or ,(comma), periods(incorrect) will be replace with comma(correct)

Conclusion

1. Support more time format (even wrong format)
2. Have extensive test
