Command line arguments (options) can be:

• --compress or -c

  Choose the compressor to use. This option is definitely subject to future changes as it works like a numeric “selector”. There are currently four compressors which can be chosen by repeatedly giving the c option. Compressor #4 (RLE encoding and Huffman table compression) is activated like so: -cccc.

• --debug or -d

  Takes a hexadecimal number as value to activate debugging output. Flags can be ORed together from these:

  • 0x01 — Token reading
  • 0x02 — States information
  • 0x04 — Driver actions (shifts, reduces, accept…)
  • 0x08 — Parse Stack dump
  • 0x10 — Error Recovery tracing
  • 0x20 — Identifier mapping (obfuscate stage)
  • 0x40 — General information

• --no-encode or -E

  String encoding will be turned off. See the features page for details.

• --file or -f

  Read input from a given file rather than from STDIN.

• --hash-encrypt or -H

  Turn on obfuscation of hashes. See the features page for details.

• --no-auto-insert or -I

  Turn off automatic semicolon insertion.

• --no-logo or -L

  Suppress the “a general eyesore” message and copyright information in the output.

• --no-mapping or -M

  Variable and function name substitution will not take place. See the features page for details.

• --map-from-scope or -m

  Begin variable and function name substitution at a certain scope level. Argument is numeric and indicates the depth of scope beginning at level zero.

• --newlines or -n

  By default, the generated output is a one-liner. Passing this numeric option enables insertion of newline characters under certain conditions:

  • 0x01 — newline after ‘;’ (“one statement per line”)
  • 0x02 — newline after scope-closing brace ‘}’
  • 0x04 — newline after ASSIGN operations
  • 0x08 — newline after RETURN statements

• --output or -o

  Write output to file specified through this option instead of STDOUT.

• --option or -O

  Pass options to modules like the compressor. Value should be <Module>=<Options> where <Module> could be Yaso::Filter::Compress4 and options are passed as a comma delimited key-value list: verbose:1,debug:0.
