Why?

Why this one special? There are plently SRT parser 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

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 :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:

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
