Dear Devs."
Suggestions:
1) shebang support so ignore first line with "#"
2) support to "<" and "|" so to read it from standard input
3) extends for two source file
//file exec-cmd that it is anywhere on PATH
//cjava is just link to java command
#!/usr/bin/env cjava --source 11 --delegation cmd
public class GeneralCommand {
onXY() ...
}
//in working directory in file "cmd"
public class Command extends GeneralCommand {
onXY() ...
}
> exec-cmd
So after execution as usual compile GeneralCommand class
and then regarding to "--delegation"
it will be searching for "cmd" in working directory
if it finds match then compile it and instead of calling
main method of General Command call main method of
Command.
As this is was even previously easily realizable by jjs
via load() to have common share logic for any command,
but exact execution-logic or just written custom
handlers or configurations separated into more files.
So only installation-care is to place exec-cmd somewhere
PATH and creation link cjava to exact java and of
course write own exact command. And when you
extend exect-cmd you just replace it and everything
is working (so no need for merging and so on).
On Microsoft Windows
> exec-cmd //exect-cmd.cmd | .bat
java --source 11 --delegation %CD%/cmd %~dp0/cmd-exec
