nqp
nqp(1) User Contributed Perl Documentation nqp(1)NAME
nqp - Not Quite Perl Compiler
SYNOPSIS
nqp [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)
-e program one line of program
-h, --help display this help text
--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-backtrace display a low level backtrace on errors
Note that only boolean single-letter options may be bundled
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
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.
