Foldiff

Easily configurable tool to get the difference between a reference folder and others

Usage

$ ruby compare.rb [--config=config.txt] [-s] [-q] [-f] [-e] reference folders_to_compare

Long form	Short	Description
--config=filename		file containing rules for comparison
--file-output	-f	writes reports to file named compare_FOLDERNAME.txt
--quiet	-q	quiet doesn't print the output to the term (without --file-output, it doesn't really make any sense)
--skip-empty	-s	skip empty files
--show-equals	-e	show the files also that don't differ

Config file

# COMPLETE is a list of file to exclude completely from the comparison
COMPLETE

    other_file_to_exclude
END

# By default, the file diff isn't showed, the report only informs that it differs from the reference.
# Add a FILE tag to display it :
FILE "ex.txt" END

# You can alter the behavior for the file by added these options before the END tag
FILE "example.txt"
    SORT # sort alphabetically the output

    HIDE_MISSING # hide missing files from the reference folder
    HIDE_ADDED # hide the files not in the reference folder

    PARSE ONLY # don't show the diff of the file, just print it
    PARSE ALSO # print the file after the diff

    KEEP_LINES      3,-6 # cut the document before making the diff (negative values begins from the end)

    PRE_REGEX       "s/^[aze]/aze/" # substitution applied before separating lines (there can be as many as you want !)
    REGEX           "s/^[aze]/aze/" # substitution applied after separating lines (there can be as many as you want !)
    
    REGEX 20 "s/a/e/" # apply it twenty times same for PRE_REGEX (not that it may slow down the analysis)
    
    # Those can also be used along with PARSE to change how the file will be parsed
    # (if either PARSE ONLY or PARSE ALSO is set)
    PARSE SORT
    PARSE KEEP_LINES 3,-6
    PARSE REGEX
    PARSE PRE_REGEX

    INCLUDES        "word" # keep only lines including *word* after the regex
    EQUALS          "line" # keep only lines matching exactly *line* after the regex
