Using the Bash++ compiler
Basic usage
bpp [options] [file] ...
$ bpp program.bpp # Compile & immediately run the program
$ bpp -o compiled.sh program.bpp # Compile & save the program to compiled.sh
$ bpp -o - program.bpp # Compile & print the program to stdout
$ cat program.bpp | bpp # Pipe previous command output to the compiler
$ bpp -h # Display help
$ bpp -v # Display version
Options
-o
or--output
: Specify the output file- If the output file is
-
, the program will be printed to stdout - If the output file is not specified, the program will be executed immediately after compilation
- If the output file is
-s
or--no-warnings
: Suppress warnings-I
or--include
: Add a directory to the include path- The default include path is
/usr/lib/bpp/stdlib
- Files in the include paths can be included with
@include <file>
- The default include path is
-t
or--tokens
: Display lexer output (do not compile)-p
or--parse-tree
: Display parse tree (do not compile)-h
or--help
: Display help-v
or--version
: Display version
If no input file is specified, the compiler will read from stdin.
Arguments after the input file are passed to the compiled program.
Include Paths
When an include directive is given with angle-brackets (as in @include <file>
), the compiler will search for the file in the include paths. By default, /usr/lib/bpp/stdlib
is the first include path.
Multiple include paths can be added with the -I
option. The paths are searched in the order they are given.
