function FILE_CHECKSUM Purpose: Returns: SHA1 CHECKSUM string for a file Usage: output = file_checksum( filename, [/add_mtime] ) Typical usage: file_hash( file_search('*') ,/add_mtime ) ; Origin: Mostly copied from file_touch Limitations: Currently works only on Linux and MacOs systems by calling the shasum command in a shell. This module is under development. Author: Davin Larson (davin@ssl.berkeley.edu) copyright - March 2014 Changes: December 2014 - Name changed from file_hash to file_checksum because is better reflects its true purpose License: All users are granted permission to use this unaltered code.

Procedure generate_checksums Purpose: recursively creates checksum files in subdirectories. These files are produced using the "shasum" program. The same program can be used to check file integrity Files are not regenerated if the chksum file is newer than all of its dependents. Usage: Typical usage: generate_checksums,directorypath,FILE_PATTERN='*.cdf' input: directorypath - scaler string filepath (must end with '/') FILE_PATTERN : string(s) file format string(s) use for search. Defaults to '*' DIR_PATTERN : string(s) directory format to be searched recursively [optional] RECURSE_LIMIT : default is 10. Set to 0 to create a single checksum file containing all files found. FORCE_REGEN : Set this keyword to force regeneration of all checksums INCLUDE_DIRECTORY : Set this keyword to compute the checksum of the checksum files in subdirectories. FULL_PATH : set this keyword to include the full path in the checksum file. (not recommended) VERBOSE: set verbosity level Limitations: Currently works only on Linux and MacOs systems by calling the shasum command in a shell. This module is under development.

Procedure: socket_reader PURPOSE: This tool is a generic multi purpose object that can read data from: 1) regular files 2) data streams (a socket) 3) array of bytes It will optionally record data to a file It is typically used by a higher level object which inherits the methods and possibly overload some of the methods. In particular the following object all call this object: cmblk_reader() ; reads common block data (files or sockets) that typically contain all of the following data types ccsds_reader() ; reads ccsds packet data (files or sockets) ccsds_frame_reader() ; reads ccsds frame data (still in development) json_reader() ; reads json files gsemsg_reader() ; reads SSL "silver box" (swemulator or swifulator output) ascii_reader() ; ascii text files with each line of text ending with a newline character. It is very common for a hierarchy of nested streams to exist in a single file or stream. Widget tool that opens a socket and reads streaming data from a server (host) and can save it to a file or send to a user specified routine. This tool runs in the background. Keywords: file_timeres : defines how often the current output file will be closed and a new one will be opened DIRECTORY: string prepended to fileformat when opening an output file.
