Huginn implementation provides four modes of operation:
Scripts
Shortest possible valid huginn program:
1
main(){}
To execute this program one must explicitly invoke huginn interpreter, e.g.:
[amok@vegeta](2/1)~/$ huginn --no-argv shortest.hgn
[amok@vegeta](2/1)~/$ echo 'main(){}' | huginn
[amok@vegeta](2/1)~/$
Shortest possible "standalone" huginn program:
1
2
#! /path/to/huginn
main(a){a;}
To execute this program one can run this program directly:
[amok@vegeta](2/1)~/$ ./shortest-standalone.hgn [amok@vegeta](2/1)~/$
Shortest possible portable huginn program:
1
2
3
4
#! /bin/sh
exec huginn --no-argv -E "${0}" "${@}"
#! huginn
main(){}
This form shall work as long as huginn interpreter can be found in user's $PATH.
[amok@vegeta](2/1)~/$ ./shortest-portable.hgn [amok@vegeta](2/1)~/$
Canonical Hello World program written in huginn, from now on we use suggested coding style:
1
2
3
4
5
6
7
8
9
10
11
12
#! /bin/sh
exec huginn -E "${0}" "${@}"
#! huginn
main( argv_ ) {
if ( size( argv_ ) > 1 ) {
print( "Hello {}!\n".format( argv_[1] ) );
} else {
print( "Hello World!\n" );
}
return ( 0 );
}
Program output:
[amok@vegeta](2/1)~/$ ./hello.hgn Hello World! [amok@vegeta](2/1)~/$ ./hello.hgn Huginn Hello Huginn! [amok@vegeta](2/1)~/$
