Functions that return a boolean based upon some criterion that matches something, often a PostFam. Useful when filtering Postings.

Instances

Eq Comp

descComp :: Ord a => Comp -> (Text, a -> a -> Bool)

Describes a Comp, and returns a function to actually perform comparisons.

date :: Comp -> UTCTime -> LPdct

qty :: Comp -> Qty -> LPdct

drCr :: DrCr -> LPdct

debit :: LPdct

credit :: LPdct

commodity :: Matcher -> LPdct

account :: Matcher -> LPdct

accountLevel :: Int -> Matcher -> LPdct

accountAny :: Matcher -> LPdct

tag :: Matcher -> LPdct

reconciled :: LPdct

True if a posting is reconciled; that is, its flag is exactly R.

clonedTransactions :: Transaction -> Transaction -> Bool

Returns True if these two transactions are clones; that is, if they are identical in all respects except some aspects of their metadata. The metadata that is disregarded when testing for clones pertains to the location of the transaction. (Resembles cloned sheep, which are identical but cannot be in exactly the same place.)

clonedTopLines :: TopLine -> TopLine -> Bool

Returns True if two TopLines are clones. Considers only the non-metadata aspects of the TopLine; the metadata all pertains only to the location of the TopLine. The DateTimes are compared based on both the local time and the time zone; that is, two times that refer to the same instant will not compare as identical if they have different time zones.

clonedPostings :: Posting -> Posting -> Bool

Returns True if two Postings are clones. Considers only the non-location-related aspects of the posting metadata.
