Large array literal split into one line per element

[williamfgc]

Large array literals (hardcoded values in code):

mats[1:34,1] = Int32[ 58, 59, 60, 61, 40, 42, 43, 44, 45, 46,  1,  2,  3,  7, 8,  9, 10, 29, 57, 47, 48,  0, 62 ]

are formatted as:

mats[1:34, 1] = Int32[
        58,
        59,
        60,
        61,
        ....

reducing readability and increasing the number of lines of code linearly.

Not sure if this is a feature of a bug. This is reproducible in VSCode and from the REPL with Julia v1.7 and JuliaFormatter v0.22.7 .
For now I'm just disabling formatting with #! format: off and #! format: on. Thanks!

this will happen if the line length is over the maximum margin. You could also try out setting join_lines_based_on_source to true and see if that results in something you'd prefer. This will still consider the the maximum margin but it shouldn't result in the above format.

This is pretty much a feature / stylistic choice. Either everything is on one line or everything is on its own line. In principle while this could be changed, it would lead to quite different behaviour for many things which I don't really want to put users through. I think format off and on is the right choice here.
