       procyon [options] <type names or class/jar files>


       Procyon  is  a  Java decompiler handling language enhancements from Java 5 and beyond that
       most other decompilers don't. It also excels in areas where others fall short. Procyon  in
       particular does well with:
        * Enum declarations
        * Enum and String switch statements
        * Local classes (both anonymous and named)
        * Annotations
        * Java 8 Lambdas and method references

       Procyon offers three output modes:
        * Java (default)
        * Raw Bytecode (similar to javap, but prettier; run with -r)
        * Bytecode AST (an intermediate representation; run with -b, add -u for unoptimized)

       One  or  more  types  can be passed as an argument to be processed. The input types can be
       fully-qualified  names   in   dotted   or   binary   form   (e.g.,   java.lang.String   or
       java/lang/String)  or  relative/absolute  file paths (path/to/MyClass.class) or even whole
       jar files.  If a type name is passed, Procyon will attempt to load it out of the  user  or
       bootstrap classpath.


       -b, --bytecode-ast

              Output Bytecode AST instead of Java.  Default: false

       -ci, --collapse-imports

              Collapse  multiple  imports  from  the  same package into a single wildcard import.
              Default: false

       -cp, --constant-pool

              Includes the constant pool when displaying  raw  bytecode  (unnecessary  with  -v).
              Default: false

       -dl, --debug-line-numbers

              For  debugging,  show  Java  line numbers as inline comments (implies -ln; requires
              -o).  Default: false


              Disable 'for each' loop transforms.  Default: false

       -eml, --eager-method-loading

              Enable eager loading of  method  bodies  (may  speed  up  decompilation  of  larger
              archives).  Default: false

       -ent, --exclude-nested

              Exclude nested types when decompiling their enclosing types.  Default: false

       -ei, --explicit-imports

              [DEPRECATED]  Explicit  imports  are  now  enabled by default.  This option will be
              removed in a future release.  Default: false

       -eta, --explicit-type-arguments

              Always print type arguments to generic methods.  Default: false

       -fsb, --flatten-switch-blocks

              Drop the braces statements around switch sections when possible.  Default: false

       -?, --help

              Display this usage information and exit.  Default: false

       -jar, --jar-file

              [DEPRECATED] Decompile all classes in the specified jar  file  (disables  -ent  and

       -lc, --light

              Use  a  color  scheme designed for consoles with light background colors.  Default:

       -lv, --local-variables

              Includes the local variable tables when displaying raw bytecode  (unnecessary  with
              -v).  Default: false

       -ll, --log-level

              Set the level of log verbosity (0-3).  Level 0 disables logging. Default: 0

       -mv, --merge-variables

              Attempt  to  merge  as  many  variables  as  possible.   This  may  lead  to  fewer
              declarations, but at the expense of inlining and useful naming.   This  feature  is
              experimental and may be removed or become the standard behavior in future releases.
              Default: false

       -o, --output-directory

              Write decompiled results to specified directory instead of the console.

       -r, --raw-bytecode

              Output Raw Bytecode instead of Java (to control the level of detail, see: -cp, -lv,
              -ta, -v).  Default: false

       -ec, --retain-explicit-casts

              Do not remove redundant explicit casts.  Default: false

       -ps, --retain-pointless-switches

              Do not lift the contents of switches having only a default label.  Default: false

       -ss, --show-synthetic

              Show synthetic (compiler-generated) members.  Default: false

       -sm, --simplify-member-references

              Simplify  type-qualified member references in Java output [EXPERIMENTAL].  Default:

       -sl, --stretch-lines

              Stretch Java lines to match original line numbers (only  in  combination  with  -o)
              [EXPERIMENTAL].  Default: false

       -ta, --type-attributes

              Includes  type  attributes  when  displaying  raw  bytecode  (unnecessary with -v).
              Default: false


              Enable Unicode  output  (printable  non-ASCII  characters  will  not  be  escaped).
              Default: false

       -u, --unoptimized

       -ln, --with-line-numbers

              Include line numbers in raw  bytecode  mode;  supports  Java  mode  with  -o  only.
