CRYSTAL-TOOL-DEPENDENCIES(1)     Crystal Compiler Command Line Reference Guide

NAME
       crystal-tool-dependencies - Show tree of required source files.

SYNOPSIS
       crystal tool dependencies [options] [programfile]

OPTIONS
       -D FLAG, --define=FLAG
           Define a compile-time flag. This is useful to conditionally define
           types, methods, or commands based on flags available at compile
           time.  The default flags are from the target triple given with
           --target-triple or the hosts default, if none is given.

       -f FORMAT, --format=FORMAT
           Output format 'tree' (default), 'flat', 'dot', or 'mermaid'.

       -i PATH, --include=PATH
           Include path in output.

       -e PATH, --exclude=PATH
           Exclude path in output.

       --error-trace
           Show full error trace.

       --prelude
           Specify prelude to use. The default one initializes the garbage
           collector. You can also use --prelude=empty to use no preludes.
           This can be useful for checking code generation for a specific
           source code file.

       --verbose
           Show skipped and heads of filtered paths
