Executing 'bin/xy.rs' runs scriptisto itself, instead of script ('./bin/xy.rs' works as expected)

[d4h0]

Expected Behavior

Executing bin/xy.rs executes the target script.

Actual Behavior

scriptisto itself is executed.

This works:

[dh@arch]$ ./bin/cli.rs
Hello, Rust! Command line options: Opt { input: None } 

This doesn't work (notice the missing "./"):

[dh@arch]$ bin/cli.rs 
scriptisto 0.6.10
A 'shebang-interpreter' for compiled languages

USAGE:
    scriptisto [ARGS] [SUBCOMMAND]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

ARGS:
    <script-src>    A path to a script to run. If specified, first character must be "." or "/"
    <args>...       Additional arguments passed to a script

SUBCOMMANDS:
    build       Build a script without running
    cache       Build cache operations
    help        Prints this message or the help of the given subcommand(s)
    new         Prints an example starting script in a programming language of your choice
    template    Manage custom script templates
[dh@arch abalet.com]$ 

Steps to Reproduce the Problem

1. Run: mkdir bin
2. Run: scriptisto new rust bin/foo.rs
3. Run: chmod +x bin/foo.rs
4. Run: bin/foo.rs

Specifications

• Version: scriptisto 0.6.10
• Platform: Linux

Hey @igor-petruk,

would you mind releasing a new version that takes advantage of the fix ?

Cheers !

[igor-petruk]

Hi,

I tried, but then I had to yank it. I think I've broken the argument passing. I am trying to fix it now

[ngirard]

Oh. Good luck with that & thanks for your feedback !

[igor-petruk]

Ok, now I think it is ok, I've done the release.

The code is somewhat ugly, so I anticipate to split the tool in two binaries, making a separate scriptisto-run binary purely as the shebang interpreter, that can unambiguously know that it is not suppose to invoke structopt ever. For now there is a lot of guesswork. This should also make the runtime faster

An alternative would be to keep one binary and behave differently according to the invocation name, like BusyBox / RustyBox.
