Description
After installing dotty 0.16 and calling 'dotr' from a cygwin bash shell environment, error messages are printed. Here are the first few lines of the error message, but to see the whole thing, just type 'cygpath' with no arguments.
Usage: cygpath (-d|-m|-u|-w|-t TYPE) [-f FILE] [OPTION]... NAME...
cygpath [-c HANDLE]
cygpath [-ADHOPSW]
cygpath [-F ID]Here is the relevant script section, centered near line 100 of bash script dotty/bin/common:
minimized code
find_lib () {
local lib=$(find $PROG_HOME/lib/ -name "$1")
if $cygwin; then
cygpath -am $lib
elif $mingw; then
echo $lib | sed 's|/|\\\\|g'
else
echo $lib
fi
}Because the "scala-xml" library is not distributed with dotty 0.16, 41 lines of error message are printed, due to cygpath being called with no file path argument.
The following is the call that triggers an error message, either because scala-xml jar file is missing, or because find_lib() need to avoid calling cygpath when the library is missing:
SCALA_XML=$(find_lib "*scala-xml*")expectation
No error messages.
Adding 2 lines to test 'lib' for the empty string would seem to be a general fix:
find_lib () {
local lib=$(find $PROG_HOME/lib/ -name "$1")
if [ -z "$lib" ]; then
echo
elif $cygwin; then
cygpath -am $lib
elif $mingw; then
echo $lib | sed 's|/|\\\\|g'
else
echo $lib
fi
}
