NAME¶
perl6 - Rakudo Perl 6 Compiler
SYNOPSIS¶
perl6 [switches] [--] [programfile] [arguments]
DESCRIPTION¶
With no arguments, enters a REPL. With a "[programfile]" or the
"-e" option, compiles the given program and by default also executes
the compiled code.
-c check syntax only (runs BEGIN and CHECK blocks)
--doc extract documentation and print it as text
-e program one line of program
-h, --help display this help text
-n run program once for each line of input
-p same as -n, but also print $_ at the end of lines
--target=[stage] specify compilation stage to emit
-t, --trace=[flags] enable trace flags, see 'parrot --help-debug'
--encoding=[mode] specify string encoding mode
-o, --output=[name] specify name of output file
-v, --version display version information
--stagestats display time spent in the compilation stages
--ll-exception display a low level backtrace on errors
--profile print profile information to standard error
Note that only boolean single-letter options may be bundled
Output from "--profile" can be visualized by "kcachegrind".
Supported stages for --target are:
parse past post pir evalpmc
where
parse = a representation of the parse tree
past = an intermediate format representing the parrot abstract syntax tree
post = an intermediate format representing the parrot opcode syntax tree
pir = the parrot intermediate representation
List of env vars used in Rakudo¶
- "RAKUDOLIB", "PERL6LIB" (src/core/terms.pm)
- Appends a delimited list of paths to @INC. "RAKUDOLIB" is
evaluated first.
- "RAKUDO_MODULE_DEBUG" (src/Perl6/ModuleLoader.pm)
- If set to a non-false value, causes the module loader to print debugging
information to standard error.
- "RAKUDO_ERROR_COLOR" (src/core/Exception.pm)
- Controls whether to emit ANSI codes for error highlighting. Defaults to
true if unset, except on Win32.
PARROT OPTIONS¶
To specify options to the underlying parrot VM, you must explicitly run parrot;
you cannot specify these options by using the "perl6" executable.
parrot [parrot switches] perl6.pbc [switches] [--] [programfile] [arguments]
See "parrot --help" for a list of valid parrot options.
