- Added "Split" button for Song editor:
  This adds the currently selected Verses tag to
  the given position, thus creating a "Force split"
- Increased Optional Split limit from < 5 to < 51
- Increased test coverage

Cannot test as the UI is not visible.
There will be more comments when it works

review: Needs Fixing

[Azaziah (suutari-olli)]

Could you explain "Cannot test as the UI is not visible." ?

I replied to the other comments, thank you for the review.

[Tim Bentley (trb143)]

You have and Insert button which is not visible - simple.

[Azaziah (suutari-olli)]

> You have and Insert button which is not visible - simple.

Did you read my replies to code comments?

"What do you mean? The UI is the new "Split" button found in song editor,
in both "Edit all" and "Edit" modes."

This is visible for me, if it is not visible for you, then something has gone horribly wrong.

[Tim Bentley (trb143)]

Ok found it now as the button is only visible on Edit All.

All the button does is add a ---[Verse X]--- tag which is the same as the splt button does except that the split button has more options.

Why is this request needed because it would seem we have the required functionality already.

[Tomas Groth (tomasgroth)]

I think the idea is to force s split inside a verse - bot correct me if I'm wrong.
If that is the idea, then the button should also be available in single verse edit.

- Improved this on Edit single verse (This now detects if the verse type is changed)

Not sure if I understand this sentence, but:

With the "Split" button, the verse will be force splitted by using the verse tag.
This is easier than selecting the verse manually and then inserting it to the required position.
A lot of people are confusing the meaning of Optional split and try to perform force splits with it.
A lot of people have requested easier way to force split verses.

> Ok found it now as the button is only visible on Edit All.

Again: This is visible for me in: Edit, Edit all & Add,
are you sure this button is not visible for you as well?

This button is available in single verse edit, as well it is available in "Add" verse.
I believe TRB143 may has missed it or something very weird is happening.

Merged trunk (Noticed tests appear to be fixed)

2666. By Azaziah on 2016-05-29

- Fixed the issue whre verse current number is not updated properly on edit single verse mode.

2667. By Azaziah on 2016-06-16

Merged trunk?

Merged trunk?

2669. By Azaziah on 2016-06-16

Reverted the perfectly functioning Verse split technigue and replaced it with insert [--].
This still needs to be turned into force split in renderer.py

2670. By Azaziah on 2016-07-02

- This is broken / Going to revert to older solution after this.

2671. By Azaziah on 2016-09-07
