hledger-lib-0.14: Reusable types and utilities for the hledger accounting tool and financial apps in general.



AccountNames are strings like assets:cash:petty, with multiple components separated by :. From a set of these we derive the account hierarchy.



subAccountNamesFrom :: [AccountName] -> AccountName -> [AccountName]Source

From a list of account names, select those which are direct subaccounts of the given account name.

accountNameTreeFrom :: [AccountName] -> Tree AccountNameSource

Convert a list of account names to a tree.

newtype Tree' a Source


T (Map a (Tree' a)) 


Eq a => Eq (Tree' a) 
Ord a => Ord (Tree' a) 
Show a => Show (Tree' a) 

mergeTrees :: Ord a => Tree' a -> Tree' a -> Tree' aSource

pathtree :: [a] -> Tree' aSource

fromPaths :: Ord a => [[a]] -> Tree' aSource

elideAccountName :: Int -> AccountName -> AccountNameSource

Elide an account name to fit in the specified width. From the ledger 2.6 news:

   What Ledger now does is that if an account name is too long, it will
   start abbreviating the first parts of the account name down to two
   letters in length.  If this results in a string that is still too
   long, the front will be elided -- not the end.  For example:

Expenses:Cash           ; OK, not too long
     Ex:Wednesday:Cash       ; Expenses was abbreviated to fit
     Ex:We:Afternoon:Cash    ; Expenses and Wednesday abbreviated
     ; Expenses:Wednesday:Afternoon:Lunch:Snack:Candy:Chocolate:Cash
     ..:Af:Lu:Sn:Ca:Ch:Cash  ; Abbreviated and elided!
