Why?

Why this one special? There are plently SRT parser on npm like:

• subtitles-parser: Last update(on npmjs): 2013-10-17
• subtitles-parser-vtt: Last update: 2020-2-14
• subtitle: Last update: 2019-4-4
• srt: Last update: 2012-7-18

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

Or this:

1:00:11,5

Similiar, 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 ✅	Yes ✅	00:00:01,544
00:00:01.544	❓ Yes for some of them	Yes ✅	00:00:01,544
00:00:01.54	❓ Yes for some of them	Yes ✅	00:00:01,544
00:00:00.3333	No ❌	Yes ✅	00:00:00,333
00:00:00.3	No ❌	Yes ✅	00:00:00,300
1:2:3.4	No ❌	Yes ✅	01:02:03,400

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. Seperator 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

Why I write this?

I am writing Tern - Subtitle File Translator

Some of the user says they have trouble translate some of the .srt file

And I found out these .srt file have format like 00:00:01.544 and 00:00:00.05

that's why I write this
