Convert-ProgettoSnapsCategoryIniFilesToCsv.ps1

# Convert-ProgettoSnapsCategoryIniFilesToCsv.ps1 is designed to take the "category.ini" files
# from AntoPisa's website progettosnaps.net and convert then to a tabular CSV format. In doing
# so, additional category information for each ROM (e.g., a list of arcade ROMs excluding BIOS
# files, a list of cloned arcade ROMs, a list of nonworking ROMs, etc.) can be combined with
# other data sources (e.g., using Join-Object in PowerShell, Power BI, SQL Server, or another
# tool of choice) to make a ROM list.

    # Five or six positional arguments are required:
    #
    # The first argument is a reference to an object that will be used to store output
    # The second argument is a string representing the file path to the ini file
    # The third argument is an array of characters that represent the characters allowed to
    #   indicate the start of a comment. Usually, this should be set to @(';'), but if hashtags
    #   are also allowed as comments for a given application, then it should be set to
    #   @(';', '#') or @('#')
    # The fourth argument is a boolean value that indicates whether comments should be ignored.
    #   Normally, comments should be ignored, and so this should be set to $true
    # The fifth argument is a boolean value that indicates whether comments must be on their
    #   own line in order to be considered a comment. If set to $false, and if the semicolon
    #   is the character allowed to indicate the start of a comment, then the text after the
    #   semicolon in this example would not be considered a comment:
    #   key=value ; this text would not be considered a comment
    #   in this example, the value would be:
    #   value ; this text would not be considered a comment
    # The sixth argument is a string representation of the null section name. In other words,
    #   if a key-value pair is found outside of a section, what should be used as its fake
    #   section name? As an example, this can be set to 'NoSection' as long as their is no
    #   section in the ini file like [NoSection]
    # The seventh argument is a boolean value that indicates whether it is permitted for keys
    #   in the ini file to be supplied without an equal sign (if $true, the key is ingested but
    #   the value is regarded as $null). If set to false, lines that lack an equal sign are
    #   considered invalid and ignored.
    # If supplied, the eighth argument is a string representation of the comment prefix and is
    #   to being the name of the 'key' representing the comment (and appended with an index
    #   number beginning with 1). If argument four is set to $false, then this argument is
    #   required. Usually 'Comment' is OK to use, unless there are keys in the file named like
    #   'Comment1', 'Comment2', etc.
    #
    # The function returns a 0 if successful, non-zero otherwise.
    #
    # Example usage:
    # $hashtableConfigIni = $null
    # $intReturnCode = Convert-IniToHashTable ([ref]$hashtableConfigIni) '.\config.ini' @(';') $true $true 'NoSection' $true

function Convert-OneSelectedHashTableOfAttributes {

    # files that have been converted to hashtables using Convert-IniToHashTable. This function
    # appends its output to the hashtable specified in the first argument. The output is a
    # hashtable (key-value pair) in the form of:
    # Key: primary key of tabular data
    # Value: PSCustomObject representing collected tabular data
    #
    # Twelve positional arguments are required:
    #
    # The first argument is a reference to an object that will be used to store output
    # The second argument is a reference to an object that serves as input. It is a "hashtable
    #   of hashtables" resulting, resulting from the collection of data using
    #   Convert-IniToHashTable
    # The third argument is a string representing the key of the input's outer hashtable. It
    #   "selects" the innner hashtable.
    # The fourth argument is either set to $null, or it's a string. If it's a string, it can
    #   either be an empty string ('') or it can be the name of one of the inner hashtable's
    #   keys, used to select the key for processing. If set to $null or '', the function
    #   assumes all inner hashtable keys need to be processed unless specified otherwise in
    #   argument five. If not set to $null or '', the function processes just the inner
    #   hashtable specified and ignores any others.
    # The fifth argument is only used if the fourth argument is not $null and not ''. In this
    #   case, it is a boolean. If set to $true, then the presence of an item in the selected
    #   hashtable is presumed to mean "affirmative" and the absense of an item is preseumed to
    #   mean "negative". See arguments 7 and 8. On the other hand, if the fifth argument is set
    #   to $false, then it is presumed that the items within the inner hashtable are key-value
    #   pairs (an inner-inner hashtable), and the key represents the item while the value
    #   represents the value for our tabular cell.
    # The sixth argument is a reference to an array. If the array has any elements, they are
    #   strings representing keys from the input's inner hashtable to ignore.
    # The seventh argument is the property name (column) to use in the output for storing the
    #   processed results
    # The eighth argument is an arbitrary object used as default, i.e., for the absense of an
    #   indicator. Usually this is 'False' or 'Unknown' - or similar.
    # The ninth argument is used only when the fourth argument is not $null or '' and the
    #   function is processing one key from the inner hashtable. The presence of an item on the
    #   inner hashtable indicates an "affirmative" - and whatever is specified in this eighth
    #   argument is stored. Usually this is 'True'. If the fourth arguement is $null or '',
    #   pass $null as the eighth argument.
    # The tenth argument is the name of the column used as the primary key.
    # The eleventh argument is a somewhat-redundant column that indicates that the primary key was
    #   processed as part of the current data set. Something like 'DataSetNamePresent' is
    #   appropriate.
    # The twelveth argument is a reference to an array of property names. Each time a new
    #   property is processed, its metadata is appended to the array and used for later calls
    #   to this function or for downstream post-processing.
    #
    # The function returns a 0 if successful, non-zero otherwise.
