Cannot edit long commands properly in REPL

[BoundaryValueProblems]

I have trouble editing some previously-used commands in REPL window now under atom-julia-client 0.6.10 under atom 1.25.1. Suppose I use the uparrow key to go through my command history and find a particular command that I want to edit and use with different parameters. Then, I have quite difficulty to edit that line (or command) now if that command line has more than 80 characters. For example, Ctrl-e does not reach the end of the command, and the delete key behaves also badly. For shorter commands, things work as before. But I just started having this problem recently. Things were OK in late January. Thanks for your help!

Yeah, this is a known problem (which has been around since the new REPL was introduced), though I didn't find an open issue for it. There are actually two issues here:

1. Console width isn't computed correctly initially, which means you get linewrapping at 80 chars (this seems to be a windows only issue). You can get around it by resizing the REPL tab once.
2. When a input line wraps around and you try to edit that, the prompt will eat the history above it. This is due to a difference in behaviour between the terminal emulator we use here and cmd, which causes an off-by-one error. This can be fixed with a patched OhMyREPL installation (or by changing the relevant code in Base and rebuilding, if you're so inclined).

Thanks a lot, @pfitzseb , for our feedback. I'm curious. In language-julia package (ver. 0.16.0), there are two items I could turn on/off: 1) Soft Wrap; and 2) Soft Wrap At Preferred Length. Do those items affect the editing behavior of long command lines?

No, the REPL isn't influenced by those options at all. This isn't something you can work around yourself except for using OhMyREPL and changing this line to miscountnl = false.
