| hledger project notes & ideas
 | |
| 
 | |
| "...simplicity of design was the most essential, guiding principle.
 | |
| Clarity of concepts, economy of features, efficiency and reliability of
 | |
| implementations were its consequences." --Niklaus Wirth
 | |
| 
 | |
| * to do
 | |
| ** TODO bugs/cleanup
 | |
| *** no total in filtered balance report
 | |
| *** register pat doesn't filter transactions
 | |
| *** two acct patterns broken
 | |
| *** better encapsulation/layering
 | |
| **** above/below cacheLedger ?
 | |
| ** ledger features
 | |
| *** handle arbitrary precision accurately
 | |
| *** handle non-convertible currencies
 | |
| *** handle time logs
 | |
| **** fix timelog parser
 | |
| **** handle time amounts
 | |
|      switch to Data.Time.*
 | |
|       fix errors
 | |
|        - read seconds to pico
 | |
|        try System.Time ?
 | |
| *** - account/description patterns
 | |
| *** -p period expressions
 | |
| *** !include
 | |
| *** -j and -J graph data output
 | |
| *** more speed
 | |
| *** full per-currency precision & thousands separator handling
 | |
| *** ledger 3-style elision
 | |
| *** -d display expressions
 | |
| *** read gnucash files
 | |
| *** other ledger 3 features
 | |
| *** single space before currency can parse as an auto transaction
 | |
| ** new features
 | |
| *** alternate timelog format
 | |
| *** infer clock-out
 | |
| *** graph automation
 | |
| *** entry and smart data entry
 | |
| *** incorporate timeclock features
 | |
| *** better layout
 | |
| ** testing
 | |
| *** better use of quickcheck/smallcheck
 | |
|      http://blog.codersbase.com/2006/09/01/simple-unit-testing-in-haskell/
 | |
| *** ledger compatibility tests
 | |
| ** documentation
 | |
| *** literate manual
 | |
| *** better use of haddock
 | |
| *** differences/issues
 | |
| **** ledger does not support -f- (without space)
 | |
| **** ledger shows description comments as part of description, we do the same
 | |
| **** ledger does not sort register by date
 | |
| **** ledger can show wrong output due to thousands separators
 | |
| **** ledger balance with an account pattern shows a redundant total
 | |
| **** hledger does not choose symbol separation, thousands separators, and precision based on first entry of each currency
 | |
|      (currently: chooses precision for all currencies based on first entry)
 | |
| **** hledger does not parse automated/periodic entries except at start of file
 | |
| * things I want to know
 | |
| ** time
 | |
| where have I been spending my time in recent weeks ?
 | |
| where have I spent my time today ?
 | |
| what is my status wrt spending plan for this week/month/year ?
 | |
| what is my current status wrt time spending goals ?
 | |
| ** money
 | |
| where have I been spending my money ?
 | |
| what is my status wrt spending plan for this week/month/year ?
 | |
| what is my current status wrt spending/savings goals ?
 | |
| what are all my current balances ?
 | |
| what does my balance history look like ?
 | |
| what does my balance future look like ?
 | |
| are there any cashflow, tax, budgetary problems looming ?
 | |
| 
 | |
| * misc
 | |
| ** compare other languages! a parser generator and decent speed is required
 | |
| *** python: http://cheeseshop.python.org/pypi/ZestyParser
 | |
| *** squeak: LanguageGame, T-Gen, SmaCC
 | |
| *** lisp: ?
 | |
| *** ruby: too slow (?)
 | |
| 
 | |
| ** data representation
