Replacing characters with the save to disk template

[Req13]

I have been trying to figure out how to use the saving books to disk template.

When I save a book that is named something like:

Mark Twain - Anthologies: How Many Are There?

I would like to replace the colon with a semicolon and remove the question mark so that it comes out as this:

Mark Twain - Anthologies; How Many Are There

Is there a way to achieve that? This is all I've been able to work out so far.

Replace ? with nothing

{authors} - {title:re(\?,)}
--------------------------------------------------------
Replace ? and : with nothing

{authors} - {title:re(\?|\:,)}
--------------------------------------------------------
Replace : with ;

{authors} - {title:re(:,;)}

I'd also like to possibly add to it if I need to change other special characters to something other than an underscore.

Thanks for any help.

One way that is easy to extend in the future.

program:
	t = $title;
	t = re(t, '\?', '');
	t = re(t, ':', ';');
# Add any more changes that you want.

FWIW: I prefer GPM templates over the other template modes.

Thank you for responding. I plugged this into the template editor in saving books to disk:

program:
	t = $title;
	t = re(t, '\?', '');
	t = re(t, ':', ';');
# Add any more changes that you want.

This outputs just the title of the book.

I was hoping to have an output of the author and title like this:

Author - Title

I can't figure out how to add the author to your code.

Thanks again.

You don't say whether you want any transforms to the authors names, or if you want all the authors or only the first. I assume no transforms and all the authors.

Use:

program:
# The authors
	a = $authors;
# Do any transforms you want to authors
# For example, to get the first author
#	a = list_item(a, 0, '&');

# The title
	t = $title;
	t = re(t, '\?', '');
	t = re(t, ':', ';');
# Add any more changes that you want.

# Construct the final output
	a & ' - ' & t

I do want all the authors with no transforms. I tried this code in the edit template box, but it wouldn't work. It comes up with this error in the template value box:

EXCEPTION: Formatter: Failed to scan program. Invalid input '& ' - ' & t' near the end of the program

I'm not sure if I needed to change something in the code or not.

You must be running an older calibre version, before calibre 5.40. Assuming you want to/must stay on the older calibre version, the code should be:

program:
# The authors
	a = $authors;
# Do any transforms you want to authors
# For example, to get the first author
#	a = list_item(a, 0, '&');

# The title
	t = $title;
	t = re(t, '\?', '');
	t = re(t, ':', ';');
# Add any more changes that you want.

# Construct the final output
	strcat(a, ' - ', t)

Sorry, I didn't realize it had been so long since I updated Calibre.

This is exactly what I'm looking for.

Thank you for your time and help.
