Shortcut to display an entire vector in the REPL

New to Julia
1

Is there a way to have the REPL not elide the middle elements from
the display of an array or vector?

This has probably been asked before but I can’t find the reference or a
solution. This is probably one of the pain points with julia for me as it
comes up all—the—time and it seems like there should be a resolution
for the issue by now.

The FAQ makes no mention. How have others solved the problem?

2 
v = collect(1:1000)
show(v)
display(v)
println(v)

Or are you looking for a more permanent solution?

Is there a reason you need display to handle this instead of looping through elements and printing what you need?

Yes.

For a one-time thing, do show(stdout, "text/plain", array) to mimic the REPL output (which happens via display) but not limit output. Or just do show(array) or println(array) to get compact (single-line) non-truncated output.

To change the REPL display globally, you can change its IOContext (see the docs here):

Base.active_repl.options.iocontext[:limit] = false

See also the summary in the manual about how the different output functions interact: Output-function summary.

I’m looking for less work in the solution that preserves the standard REPL interface.

I want the REPL to “do what I want” here without extra effort.

This appears to do what I want. Keep the same REPL interactions but not
skipping the middle elements of large displays. It would be nice if the REPL
would allow you to toggle this as a feature.

Marking this as the solution and thanks for all the reference information.

This works nicely with TerminalPager.jl

It already does, no?

That being said, I would really like to see a better API here: julia#61005.

I’ve tried and failed before to come up with a shorthand for doing this in the repl. I think it would be good to figure that out.
