Version 0.7.0 would not install on FreeBSD.
The package gave compilation errors on some macOS platforms.
Add unit test asserting that a bound port is detected as such.
Remove unnecessary whitespace prefix from the CLI help output.
port4me() would only verify that it was possible to
listen to port. Now it also verifies that the port can be
bound.
The command-line interface gave an error if special R option
--args was used as in
Rscript -e port4me::port4me --args --list=5.
Now port4me(list = n) gives an error for
n < 1.
Rscript -e port4me::port4me,
Rscript -e port4me::port4me --list=5,
Rscript -e port4me::port4me --test=8087.If argument prepend was a numeric, but not an
integer, then the return port, or ports, would also be numeric. Now
port4me() returns integer ports also when
prepend is numeric.
The R port4me::port4me() function did not default to
environment variable PORT4ME_LIST, if argument
list was not specified.
The R port4me::port4me() function did not default to
environment variable PORT4ME_TEST, if argument
test was not specified.
PORT4ME_EXCLUDE_UNSAFE,
which defaults to {chrome},{firefox}. The token
{chrome} expands to the value of
PORT4ME_EXCLUDE_UNSAFE_CHROME, which defaults to the set of
ports that are considered unsafe by the Chrome web browser and therefore
also blocked by it. Similarly, {firefox} expands to the
value of PORT4ME_EXCLUDE_UNSAFE_FIXEFOX, which defaults to
the set of ports that are blocked by the Mozilla Firefox web
browser.
