When trying to use the sample loop project, I get this error:

File: 'samples/language/9-loop.sh'
line: 81 >> files = [file for file in $(ls) if file.size("k") > 10]
Error: symbol size not found

I tried compiling this on Ubuntu 18.04.

When I was compiling the project, I got this error:

/home/ubuntu/shell-plus-plus/glob-cpp/include/glob-cpp/glob.h: In instantiation of ‘std::tuple<long unsigned int, long unsigned int> glob::StateMatch::Next(glob::String&, size_t) [with charT = char; glob::String = std::__cxx11::basic_string; size_t = long unsigned int]’:

I used Boost-msvc 1.67 and readline 8.0.

Should I try with Clang or GCC instead?

MacOS support

Do you want to add macOS support?

And how to read user input via prompt started with message> like in python a = input('message> ')?

I did not run on Mac but since the output of whereis is different on Linux and Mac, I assume the example would be broken on Mac:

# Mac
$ whereis ls
/bin/ls
$ whereis no-such-prog
(no output at all)

# Linux
$ whereis ls
ls: /bin/ls /usr/share/man/man1/ls.1.gz
$ whereis no-such-prog
no-such-prog:

I would consider which. It works the same on Mac and Linux and uses exit code to convey whether the command was found.

We can set up continuous integration to build shell-plus-plus and provide binaries.

I can help with this!
