Add dash to a continuing subtitle line?

[Rob-]

Is it possible to format a subtitle and add a hyphen to the begining and end of a continuing subtitle line? Like this:

Example sub (.srt):

1
00:00:48,966 --> 00:00:53,720
Today he was so angry and happy
at the same time,

2
00:00:53,929 --> 00:00:57,683
he went to the store and bought a
couple of books. Then the walked home

3
00:00:57,849 --> 00:01:01,102
with joy and jumped in the pool.

4
00:00:57,849 --> 00:01:01,102
One day he was in a bad mood and he
didn't get happier when he read.

TO THIS:

1
00:00:48,966 --> 00:00:53,720
Today he was so angry and happy
at the same time-

2
00:00:53,929 --> 00:00:57,683
-he went to the store and bought a
couple of books. Then the walked home-

3
00:00:57,849 --> 00:01:01,102
-with joy and jumped in the pool.

4
00:00:57,849 --> 00:01:01,102
One day he was in a bad mood and he
didn't get happier when he read.

This is the standard for scandinavian subtitles. I'm used to read subtitles in this way.

I can't figure out how to format an existing subtitle to match this "pattern". A little bit of help please. Which program should I use? Subtitle Edit?

Thank you.

In English captioning style, do not use dashes unless a sentence is interrupted for emphasis, or by another sound or speaker. (Hyphens are only for compounds.) Take care not to break phrases across captions. For example, your first three captions should be

Today he was so angry
and happy at the same time,

he went to the store
and bought a couple of books.

Then he walked home with joy
and jumped in the pool.

Thank you for your answer. I simply wrote the example subtitle in English so it's more understandable. I am still searching for a solution. Otherwishe I have to accomplish the subtitles manually with adding the dashes to almost every single line! Anyone that can help?

Maybe show an example in your language with the dash a different colour etc. Is the dash an N dash or an M dash ? Not sure if either of those could cause a problem.

Sorry, I misunderstood about the language. I believe my advice to avoid breaking phrases would apply to any Western language, but of course it's up to your preference.

I would use a regex search-and-replace in a text editor such as Notepad++. Here is the logic you need to implement:

1. Add a dash after any alphabetic character which is followed by two newlines.
2. Add a dash before any lowercase alphabetic character which is preceded by a numeral and a newline.

That's what I'm searching for. Thanks... I'm not a programmer so this seems very difficult. Could you please be more specific? What sould I replace nothing with? Is it also possible to add the dash to a line with italic tags?
