[PATCH 5/6] edksetup.sh: Simplify SetupPython3 and SetupPython functions.

[rebecca]

On Linux, "whereis" matches python3, python3.7, as well as
man pages, libs etc.  While on macOS it only matches the specified
name, and so misses python3.7. Improve this by looping over
potential version numbers and seeing if such a binary exists and
can be executed.

(Sorry if the reason was already given and I missed it:)

Why is this an improvement?

The docs at <https://man.openbsd.org/pwd.1> say:

"pwd also exists as a built-in to ksh(1), which may have a different
default behavior". Is that the reason?

Thanks!

This patch looks sane, but I don't understand why it stops here. There
are more variable references that could be quoted; for example, just
after the above, we have:

  if [ $PYTHON3_ENABLE ] && [ $PYTHON3_ENABLE != TRUE ]

Ah wait, that code is removed in patch #5.

But, I think the question stands; there's more that could be quoted.
What is the reason for quoting just these?

No, it's mainly as a (very minor) optimization: `pwd` runs the command
(even as a built-in), whereas $PWD simply evaluates the value of the
variable.

Also, modern scripts as I understand it should generally use $(...) to
run commands, instead of `...`.

Two things I'm not a fan of:
- seq for generating candidate version numbers (floating point)
- using "which" after having used "command -v"

For example, we could do:

for ((pyver=10; pyver>=1; --pyver)); do
  if python=$(command -v python2.$pyver); then
    export PYTHON_COMMAND=$python
    break
  fi
done

(It doesn't check for just "python2", but that's always a symlink
anyway, isn't it?)

The trick is that the exit status of just

  X=$(cmd)

is the exit status of "cmd":

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_09_01

"If there is no command name, but the command contained a command
substitution, the command shall complete with the exit status of the
last command substitution performed"

That said, if you wouldn't like to rework the patch, I can give my R-b
as-is (please confirm).

Mainly because I thought those were the ones that were most important to
add quotes around. I'll probably submit a follow-up patch to fix the
others and further reduce the number of shellcheck warnings.

Thanks, I like your suggested changes. And I just ran shellcheck and was
told "SC2230: which is non-standard. Use builtin 'command -v' instead.".
