Support inline execution, sub shell and shebang line execution. Hebang execution also :). The hebang line is similar to shebang just that instead of ‘#’ it expect ‘//’. The value of {0} is the full path to the file and can be used in the shebang and hebang line.
The hebang can be used to compile a file before executing it. e.g the following c source file is compiled then executed, test.c
//!gcc {0} -o test; ./test
#include <stdio>
int main() {
printf("hello world");
}
Then execute this in the CLI. The file test.c will be compile and
executed. The hebang line will expands to
gcc C:/full/path/test.c -o test; ./test
$ ./test.c
will prints ‘hello world’ in the console.
This also regocnize the webang line which allo the use of C89/C90 comment for file execuition e.g.
/*!gcc {0} -o test; ./test */
#include <stdio>
int main() {
printf("hello world for webang");
}
Then execute this in the CLI. The file test.c will be compile and
executed. The webang line will expands to
gcc C:/full/path/test.c -o test; ./test
$ ./test.c
will prints ‘hello world for webang’ in the console.
If no command is specified to the script it will enter a subshell where command can be executed line by line. The subshell is simply a powershell REPL which evaluates shebang, webang and hebang line in file if specified.
