Variable Types-

NOTES on Streams: streams are read/write. In-memory streams are cleared when their reference count drops to 0. 
Changing a stream variable's file_path will close the stream and open a new one to the new path.

• int <variable_name> = <value>
  • whole integers only
  • name is restricted to A-Z, a-z, 0-9, and may contain an underscore
• str <variable_name> = "<value>"
  • value must be quoted
  • name is restricted to A-Z, a-z, 0-9, and may contain an underscore
• list <variable_name> = [<value1>, <value2>, ...]
  • name is restricted to A-Z, a-z, 0-9, and may contain an underscore
  • value list must be comma seperated
  • value list must be wrapped in [ ]
• encryptedstream <variable_name> = <file_path>
  • name is restricted to A-Z, a-z, 0-9, and may contain an underscore
  • filepath must be a valid windows filepath
  • output will always be compressed and encrypted
  • declaring a stream as stream <variable_name> or stream <variable_name> = '' will make the stream an in memory stream
• plaintextstream <variable_name> = <file_path>
  • name is restricted to A-Z, a-z, 0-9, and may contain an underscore
  • filepath must be a valid windows filepath
  • output will always be uncompressed and unencrypted
  • declaring a stream as stream <variable_name> or stream <variable_name> = '' will make the stream an in memory stream

Commands

we need a method to return values from module commands

we also need to support environment variables as part of filepaths;  the core will take responsibility for expanding them prior to use on the target system

module commands need to be able to support the '.' character to allow pseudo-namespacing for modules

Core functions

Modules

    • string/int value can be a raw string/int or a variable of type string
    • stream must be a user defined stream type or a reserved stream type
• dirlist - performs a dir walk starting at a specified location; depth and other considerations might be extra options to this
  
  • dirlist <start path> <stream>

    • stream must be a user defined stream type or a reserved stream type
  • returns a list of containing the results of the dir walk
• archive - combine a file into an archive
  
  • archive <filepath/archivename> <filepath/filename>; 
  • archive <filepath/archivename> <list of files>
    
    • filepaths must be valid windows filepaths
    • the file combined should be secure deleted
  • returns a status code which indicates success or failure
• unpack - pack another executable into the reforge package and extract it to a specified location on target
  
  • unpack <filepath to execuable> <extract location>
    
    • executable path can be a valid linux or windows filepath
    • extract location must be a valid windows filepath
    • both inputs can be a raw string or a variable
  • returns a status code indicating success or failure
• proclist - get a process list
  • proclist <stream>
    • stream must be a user defined stream type or a reserved stream type
  • returns a list of lists containing process related information
• netstat - get a netstat
  • netstat <stream>
    • stream must be a user defined stream type or a reserved stream type
  • returns a list of strings containing netstat information
• registry - set, edit, or delete a registry key
  • registry <operation> <key> <type> <value>
    • operation can be create, set, or delete
    • key can be a raw string or a variable of type string
    • type can be REG_BINARY, REG_SZ, REG_DWORD
    • value can be a raw string, raw int, or a variable of type int or str
  • returns a status code indicating success or failure
• enzip - compress and encrypt a file
  • enzip <input file> <output file>; this command may be obsolete if encrypted stream supports compression
    
    • input/output files must be valid windows file paths
    • input/output files can be raw strings or variables of type string
    • input can also be a stream which causes the stream to close
    • should we allow compress and encrypt of the same file in place?
  • returns a status code to indicate success or failure
• run - run a program or a system command on the command line and wait for its completion
  • run <cmd> <stream>
    • cmd can be a raw string or a variable of type string
    • cmd must contain full path to the executable to run and any args if these things are necessary
    • run must wait till the command is finished
    • stream must be a user defined stream type or a reserved stream type
  • return a status code to indicate success or failure and a string containing the results of the command?
• start - run a command or program on the command line but don't wait for its completion
  • start <cmd>
    
    • cmd can be a raw string or a variable of type string
    • cmd must contain full path to the executable to run and any args if these things are necessary
    • start does not wait till the command is finished
  • return a status code to indicate success or failure
• for - for each loop

  • for <x> in <y> { <cmds> }

    • for each <x> item in <y> do the commands in the <cmds> block
    • <y> is a list of items or the base of a directory to iterate over
    • if <y> is a base dir then it must be a valid windows filepath
    • the cmds block can contain any command supported by reforge 
    • For loop can take a path as the <y> param that allows the for to do a for each in path
      • for <files>[,<dirs>] in <path>
        • if only files is specified the for loop will not follow sub directories
        • if dirs param is provided a second for loop can be used to follow subdirectories.
• while - loop while a condition is true
  • while( <condition>) { <cmds> }
    • condition must be in the form <x> <operator> <y> where x and y are of the same type
      
      • condition operators can be <,>, <=,>=, or =
      • x and y can be raw str/int or variables of type str/int
    • the cmds block can contain any command supported by reforge 
• if / if...else - conditional statement
  • if( <condition> ) { <cmds> } else { <cmds> }
    • condition must be in the form <x> <operator> <y> where x and y are of the same type
      
      • condition operators can be <,>, <=,>=, or =
      • x and y can be raw str/int or variables of type str/int
    • the cmds block can contain any command supported by reforge 
    • the else part of this command is optional
• break - break out of a loop
  • break
    • will stop execution of a for, while, if or else statement and exit the loop/code block
• continue - skip over the rest of the current loop iteration
  • continue
    • only usefull in for and while loops.
    • If used in an if statement it will affect the loop the if belongs to or it will do nothing if not in a loop
• add_to_list - add an element to the end of a list
  • add_to_list <list> <value>
• remove_from_list - remove an element from a list
  • remove_from_list <list> <element number>
• set_value_in_list - change the value of a list index to a new value
  • <list>[<index>] = <value>
• get_value_from_list - get the value stored in a list index
  • <list>[<index>]
• pipe/flush - read the contents of a stream and write them to a second stream
  • pipe/flush <stream> <stream>
    • either <stream> can be plaintextstream or encryptedstream types
