Behind the scenes
How are identified applicable files
- File extensions:
.raku
,.rakumod
,.rakutest
,.pm6
,.pl6
,.p6
How the linting is performed
- raku is called one time by identified file (
file
CLI lint mode)
Example calls
raku -I ./lib -c myfile.raku
Help content
/opt/rakudo-pkg/share/perl6/runtime/perl6.moarvm [switches] [--] [programfile] [arguments]
With no arguments, enters a REPL (see --repl-mode option).
With a "[programfile]" or the "-e" option, compiles the given program
and, by default, also executes the compiled code.
- read program source from STDIN or start REPL if a TTY
-c check syntax only (runs BEGIN and CHECK blocks)
--doc extract documentation and print it as text
-e program one line of program, strict is enabled by default
-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
-I path adds the path to the module search path
-M module loads the module prior to running the program
--target=stage specify compilation stage to emit
--optimize=level use the given level of optimization (0..3)
--rakudo-home=path Override the path of the Rakudo runtime files
-o, --output=name specify name of output file
-v, --version display version information
-V print configuration summary
--stagestats display time spent in the compilation stages
--ll-exception display a low level backtrace on errors
--doc=module use Pod::To::[module] to render inline documentation
--repl-mode=interactive|non-interactive
when running without "-e" or filename arguments,
a REPL is started. By default, if STDIN is a TTY,
"interactive" REPL is started that shows extra messages and
prompts, otherwise a "non-interactive" mode is used where
STDIN is read entirely and evaluated as if it were a program,
without any extra output (in fact, no REPL machinery is even
loaded). This option allows to bypass TTY detection and
force one of the REPL modes.
--profile[=name] write profile information to a file
Extension controls format:
.json outputs in JSON
.sql outputs in SQL
any other extension outputs in HTML
--profile-compile[=name]
write compile-time profile information to a file
Extension controls format:
.json outputs in JSON
.sql outputs in SQL
any other extension outputs in HTML
--profile-kind[=name]
choose the type of profile to generate
instrumented - performance measurements (default)
heap - record heap snapshots after every garbage
collector run
--profile-filename=name
provide a different filename for profile.
Extension controls format:
.json outputs in JSON
.sql outputs in SQL
any other extension outputs in HTML
This option will go away in a future Rakudo release
--profile-stage=stage
write profile information for the given compilation
stage to a file. Use --profile-compile to set name
and format
--full-cleanup try to free all memory and exit cleanly
--debug-port=port listen for incoming debugger connections
--debug-suspend pause execution at the entry point
--tracing output a line to stderr on every interpreter instr (only if
enabled in MoarVM)
Note that only boolean single-letter options may be bundled.
The following environment variables are respected:
RAKULIB Modify the module search path
PERL6LIB Modify the module search path # to be deprecated
RAKUDO_HOME Override the path of the Rakudo runtime files
NQP_HOME Override the path of the NQP runtime files
