🐛 Cannot show long lines

[bachue]

Delta version 0.6.0, installed by cargo today
Mac OS X 10.13.6

git diff

For the long lines in diff view, I can see these are right arrows on the right side.
Then when I press the right arrow, I see this:

I still cannot see the full long line. I think it should be a bug.

Hi @bachue, this is expected behavior for side-by-side mode, so not a bug. HOWEVER, it would definitely be nice for delta to make it possible to see the full line, and there is a very exciting PR here that is adding line-wrapping to side-by-side mode: #515.

(I think the solution has to be line-wrapping. Simply pressing right arrow might work for the right panel, but it would not work for the left panel.)

Just a quick question, is it possible for delta rely on less config somehow?
For instance if I have less -FRKX, and something like

[delta]
pager = less

The lines would be shown as expected withing this issue (folded).

Or this is a completely different architecture and most of the features should be written standalone no matter to a different pagers like less one?

Thanks though.
Working without syntax for years, although using delta make my day more bright :D

@kaldown
In general, the LESS* environment variables do take effect, altough delta processes the input and then sends it to less (and applies some default less flags, in addition to $LESS). That's why for example the line wrapping/chopping might be done before less even gets the data, esp. in side-by-side mode.

I hope that makes sense 🙄 ?

For example with git diff, the data pipe is basically git-diff ➡️ delta ➡️ less; you can test the pure delta output with e.g.

git -c delta.paging=never <subcommand>

Ye, makes sense, thank you for clarification.
Perhaps due to delta features like line-number, it would be hard to process output out of less.
Or why isn't there git-diff | less | delta pipeline?

[Kr1ss-XD]

I guess there are several reasons, one of them is probably be that delta alters the number of lines because it adds headers and such. You'd want to have this done first, and then divide the output into pages.

@bachue Note that delta also has a width setting that you can use to make lines extend beyond your terminal window if you want. But in general, the solution here is going to be #515.

Thanks @Kr1ss-XD. @kaldown as @Kr1ss-XD says, you can have any less configuration that you'd like in the less process that delta starts. You are also free to set pager = less | delta in gitconfig to experiment if you want!

@kaldown Let us know here if you have any problem configuring the less process that delta starts.
