Prevent semicolon from splittings lines? A space in array

[rieje]

• Is it possible to prevent semicolon from splitting lines? I have:

  bin="$(tput bold; tput setaf 2)${0##*/}$(tput sgr0)"

which I find is preferable to the shfmted:

bin="$(
  tput bold
  tput setaf 2
)${0##*/}$(tput sgr0)"

because 1) even with the semicolons, it's shorter, 2) usually with variables with tput, it's not so important that each (tput) command warrants its own line and IMO having them on the same line is more intuitive to suggest the string it's styling is wrapped by styling, kind of like printf '---%s---' "word ". Even better shfmt splits only when the existing line is >80 chars and don't format when it's <=80 chars.

• Are there any options that take into account of width of line like >80 chars?

• shfmt formats cat > "$prof_path <<EOF to cat >"$prof_path <<EOF but the space after > makes it easier to read. In Bash, why is the convention to remove the space as in >/dev/null that I often see preferable to > /dev/null?

• Similarly, is it possible to enforce 1 space in arrays e.g. prefer arr=( "itema" "itemb" ) instead of removing the space arr=("itema" "itemb") ?

Much appreciated.

For your last two questions, see #544.

There is no planned feature or option to allow multiple commands with semicolons per line.

Regarding line length, see #80.
