[Bug-apl] APL REPL & pager

Hello y'all, Is there a simple way to either increase or eliminate the wrap width in the REPL? In vim this would be :set nowrap and using a pager would be `less -S`. I have some nested objects I inspect w/ ` 4 ⎕CR` but the wrap causes the lines to overflow and make it difficult to read. -

Hi Bug-APL, Please enjoy this link to a library I wrote. It allows APLers to read images into the APL environment. The returned data structure is a three dimensional matrix, where each plane represents a sub-pixel. Additionally, you can take a 3×X×Y sized matrix and write it as a .bmp file.

Of course. Simple scalar functions would be the worst to parallelize. We always need a large amount of operations per thread to be worthwhile. Something like the following might be a good thing to start ⌹⍤2 X where (LargeNumber = ×/¯2↓⍴X) ∧ 2<⍴⍴X To support general function instead of builtins
