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

Options:

Option	Required	Default
--input or -i	Yes
--output or -o	No	output.json
--minify	No	false

Why?

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

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

Format	Other parser	srt-parser-2	srt-parser-2 would turn this into
00:00:01,544	Yes :white_check_mark:	Yes :white_check_mark:	00:00:01,544
00:00:01.544	:question: Yes for some of them	Yes :white_check_mark:	00:00:01,544
00:00:01.54	:question: Yes for some of them	Yes :white_check_mark:	00:00:01,544
00:00:00.3333	No :x:	Yes :white_check_mark:	00:00:00,333
00:00:00.3	No :x:	Yes :white_check_mark:	00:00:00,300
1:2:3.4	No :x:	Yes :white_check_mark:	01:02:03,400

Basic principle:

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

Conclusion

Support more time format (even wrong format)
Have extensive test
