doesn't work at compile time

[timotheecour]

a few issues:

• mkstemp can't be used because we can't fopen a file at CT
• mktemp can be used but is marked deprecated, however:
• existsFile can't be used at CT
• the random name returned at CT is "FFFFFFFF", ie not random

other points

• why mark mktemp as deprecated given that it's used by mkstemp?
• sounds like a nim bug: how come nim doesn't show deprecation msg when using mkstemp given that it uses mktemp which itself is deprecated?
  EDIT: filed deprecated proc called from bar.nim doesn't give deprecation warning if bar.nimble exists nim-lang/Nim#9854

potential solution

on posix: use mktemp + gorgeEx (ie execute shell cmd at CT)
on windows: ?

eg use case:

nimterop/nimterop#27 where I need a rand file at CT

mktemp marked as deprecated because of no real file created, it may causes security issues, I will make it private soon.

I will take a look on CT when I have spare time. Thank you!

it may causes security issues, I will make it private soon.

meh, then just call it mktempUnsafe to make it clear to users; but there are useful use cases (where security is not a concern) for returning a path to a not-yet-created file (even if it could theoretically fail in adversarial circumstances); nim is a systems programming language, so should allow that IMO

greate idea, I will make some changes soon
