controlling line breaks in code

[Gojko Adzic]

Hi,

Does anyone know how to control line breaks or continuation in code samples? I have a bunch of YAML listings with long lines in code samples (can't do anything about the length, or break into multiple lines, because that's messing up with the validity of the data in YAML formatting.

Leanpub is inserting a backslash and printing a different line number in the continuation. Is there any way this can be configured, so that the content isn't modified and that the line numbers only print for actual lines?

Hi Gojko,

If you have a really long YAML string you could try the multiline
support for YAML here
https://stackoverflow.com/questions/3790454/in-yaml-how-do-i-break-a-string-over-multiple-lines
so that you can wrap the code manually.

In terms of Leanpub, our position is that code should be wrapped
manually for PDF. You can also try increasing your page size if it's
not wide enough, if you haven't already done so. That may reduce the
number of lines you need to manually wrap. Looking at your screenshot
I can't tell if this is at the largest size already or not...

Thanks
Peter

thanks, I guess I'll have to convert this to images outside leanpub then and include as a picture

Then no one will be able to copy and paste the code, or zoom in,
change font sizes, etc. Manually wrapping or even the occasional
Leanpub-inserted backslash is presumably preferable to that, no?

not in this case unfortunately, line breaks in YAML don't mix well with AWS CloudFormation function calls :( but in general I agree

Ah. Well, then just a note like this before or after the first YAML file...

W> Sometimes this book breaks long lines in YAML files with a
backslash at the end of the line, so if you are copying and pasting,
please remove the backslashes.

...is probably also preferable to images :)

Thanks
