gosub

Utility to extract the contents of a subtitle file

• srt: SubRip
• other types will be supported as soon as possible :)

Installation

Installation is done using go get.

go get -u github.com/arman-aminian/gosub

Usage

The method parse requires the following parameters:

• path: location of the subtitle file.

s, err := gosub.Parse("./Example/test.srt")
if err != nil {
    panic(err)
}

Or

file, err := os.Open("./Example/test.srt")
if err != nil {
    panic(err)
}
defer file.Close()
s, err := gosub.ParseByFile(file)
if err != nil {
    panic(err)
}

Line Struct

Each line of a subtitle is represented with a Line struct with the following properties:

• start: timestamp of the start of the dialog.
• end: timestamp of the end of the dialog.
• text: dialog contents.

for _, line := range s.Lines {
    fmt.Println(line.Start, " -> ", line.End)
    fmt.Println(line.Text)
    fmt.Println()
}

Output:

0000-01-01 00:00:00 +0000 UTC  ->  0000-01-01 00:00:30.05 +0000 UTC
first line [test test] of subtitle

0000-01-01 00:01:21.062 +0000 UTC  ->  0000-01-01 00:01:26.361 +0000 UTC
second line <i> test test<\i> of subtitle

0000-01-01 00:01:26.565 +0000 UTC  ->  0000-01-01 00:01:32.564 +0000 UTC
third line of subtitle
third 2

0000-01-01 00:01:32.768 +0000 UTC  ->  0000-01-01 00:01:37.967 +0000 UTC
Make IT lowerCase

Cleaners

Currently, 3 cleaners are provided:

• RemoveBrackets will remove anything between them (e.g., [test test])
• RemoveTags will remove formatting keys like <i> and </i> and also anything between them.
• LowerCase will lower case all text.

WPM

Calculate wpm(word per minute):

• CalculateMaxWpm will find the Max WPM.
• CalculateMinWpm will find the min WPM.
• CalculateMeanWpm will find the mean WPM.
• TotalWordCount will caclulate number of words in file.
