"...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
|
|
|
|
"The competent programmer is fully aware of the limited size of his own
|
|
skull. He therefore approaches his task with full humility, and avoids
|
|
clever tricks like the plague." --Edsger Dijkstra
|
|
|
|
"I was hesitating to cross the street in Edinburgh one day, and these two
|
|
little old Scottish ladies cried out to me 'LIVE DANGEROUSLY, SON! LIVE
|
|
DANGEROUSLY'" --kowey
|
|
|
|
ALL THAT'S NEEDED IS THE DESIRE TO BE HEARD. THE WILL TO LEARN. AND THE
|
|
ABILITY TO SEE. --Scott McCloud, Understanding Comics

How to grow the hledger project ?
|
|
|
|
I'm looking for ways to fund active and sustainable hledger
|
|
development by me and others.
|
|
|
|
A secondary goal is to develop new sustainable models and processes
|
|
for funding free software developers and other community projects.
|
|
|
|
This is sometimes the point in a free sw project's development where
|
|
the project leader seemingly loses the plot, alienates contributors
|
|
and destroys the community's good-will dynamic. I've seen it many
|
|
times, but a few have succeeded and I want to be one of them - so
|
|
that I can eat, have a modicum of stability and do my best work in
|
|
service to the community. At worst, I'll look bad but the project
|
|
will still be out there. At best I'll live more easily and joyfully
|
|
while serving the cause of Financial Solvency!
|
|
|
|
So I'm beginning by posting these notes and inviting your thoughts -
|
|
as much or as little as folks want to give. How could we do this
|
|
so that all benefit ?
|
|
|
|
funding models
|
|
==============
|
|
Brainstorming some possible funding models & processes.
|
|
|
|
* grants
|
|
|
|
How to find possible grant sources ?
|
|
|
|
* con
|
|
|
|
* getting grant funding is a whole new field to study
|
|
* slow and time intensive, I imagine
|
|
|
|
* donations
|
|
|
|
Solicit donations.
|
|
|
|
* pro
|
|
|
|
* simple
|
|
|
|
* con
|
|
|
|
* often difficult
|
|
* donators do not feel a direct benefit
|
|
|
|
* shareware
|
|
|
|
Release the project under a non-free license, requiring commercial
|
|
users to pay the fee on an honour basis (eg).
|
|
|
|
* pro
|
|
|
|
* flexible, low administration, encourages trust
|
|
|
|
* con
|
|
|
|
* effectively closed-source ? would inhibit collaboration
|
|
* benefit is still indirect, only a proportion will pay
|
|
* enforcement/guilt may come into play
|
|
|
|
* limited-time premium branch
|
|
|
|
The funded version of hledger gets some desirable premium features
|
|
before the free version and is closed-source. Funders/customers pay
|
|
a fixed price for immediate access to the funded version. Yearly, a
|
|
new funded version is released and the old funded version is merged
|
|
into the free version. (To gain experience it could be done on a
|
|
smaller scale, eg monthly/quarterly.)
|
|
|
|
* pro
|
|
|
|
* all features reach community, predictably
|
|
* customers are also community funders
|
|
* customers receive direct benefit from paying
|
|
|
|
* con
|
|
|
|
* free sw developers compete/outshine the premium branch
|
|
|
|
* bounties
|
|
|
|
Some (or all) feature, bugfix, project management or other tasks are
|
|
published with a bounty attached. When the bounty is paid by one or
|
|
more funders, the task is performed and delivered. Or, bounty is paid
|
|
on completion of task (honour system).
|
|
|
|
* pro
|
|
|
|
* funders receive direct benefit
|
|
|
|
* bounties using fundable.org (eg)
|
|
|
|
A more organised form of the above, perhaps facilitating trust,
|
|
co-funding and larger bounties.
|
|
|
|
* pro
|
|
|
|
* proven process developed by others
|
|
|
|
* con
|
|
|
|
* fundable takes a cut
|
|
|
|
* hosted service
|
|
|
|
Offer hosted and managed ledgers, perhaps with premium features, for
|
|
a monthly fee
|
|
|
|
* pro
|
|
|
|
* proven model
|
|
* clear benefit to customers, especially non-technies
|
|
|
|
* con
|
|
|
|
* success of free/self-installed version competes with hosting service
|
|
* some will avoid web-hosting their financial data
|
|
|
|
* customisation
|
|
|
|
Offer per-user customisations, possibly to be merged in the trunk,
|
|
for a fee
|
|
|
|
* support
|
|
|
|
Offer user/developer support for a fee
|
|
|
|
* training
|
|
|
|
Offer application and/or financial training for a fee
|
|
|
|
* profit sharing/tithing
|
|
|
|
Each period (quarter, half-year, year), donate 10% (eg) to project
|
|
contributors and/or supporting projects
|
|
|
|
* transparent funding
|
|
|
|
Funding and usage of funds is published on the web as a ledger
|
|
|
|
* opaque funding
|
|
|
|
All funding and spending need not be made public
|
|
|
|
strengths
|
|
=========
|
|
hledger has some aptitudes in this area:
|
|
|
|
* hledger deals with money => hledger users will tend to have some money
|
|
* hledger's purpose is to increase financial success => users will feel its value to their bottom line
|
|
* hledger is a tool that can support project funding, eg by publishing community funding data
|
|
|
|
weaknesses
|
|
==========
|
|
* hledger doesn't have a nice ui yet
|
|
* hledger has a limited featureset
|
|
* hledger requires work, eg data entry and chart of accounts maintenance
|
|
* hledger is geeky
|
|
* there is competition
|
|
* hledger has no compelling market niche (aside from payment-averse free software users)
|
|

*** parsing: support @@

*** parsing: support D

*** parsing: accept all real-world ledger files
|
|
As far as I know it currently accepts all ledger 2.6-era files.
|
|
Add support for ledger 3 file format as/when that stabilises.
|
|
It would be nice to optionally report/upload parse errors when they happen.

gather data on real-world installation & usage issues
|
|
simplify bug reporting/handling
|
|
improve reliability
|
|
*** upload feature
|
|
*** payee & account anonymisation
|
|
*** easier timelog formats
|
|
*** add: completion etc.
|
|
*** convert: generalise/reuse add's history awareness
|
|
*** web: charts (Chart or google)
|
|
*** wide/customisable/consistent layout
|
|
*** effective/actual dates for postings
|
|
*** better web ui/gui
|
|
*** nice reports with charts
|
|
*** more automated bank data conversion
|
|
*** parse more file formats - gnucash, qif, ofx, csv..
|
|
*** download via ofx protocol
|
|
*** watching a changing ledger
|
|
*** more date syntax ? last nov, next friday, optional this, week of
|
|
*** more period syntax ? every N days, biweekly
|
|
*** accept multiple -f files
|
|
*** more reliable tidy layout from print
|
|
*** i18n
|
|
*** speed, memory usage
|
|
*** clear, documented interfaces/surfaces
|
|
*** plugin architecture/modular packaging
|
|
**** goals
|
|
***** allow separately-packaged functionality to be discovered at run-time and integrated within the hledger ui.
|
|
Example: user installs hledger-ofx package from hackage, or adds Ofx.hs to their ~/.hledger/plugins/;
|
|
then "ofx" is among the commands listed by hledger --help, and/or is a new command available in
|
|
the web and vty interfaces, and/or is a new file format understood by the convert command.
|
|
**** issues to consider
|
|
***** what is the api for plugins ?
|
|
they'll want to import Ledger lib, to work with ledger data structures
|
|
|
|
***** there are different kinds of "plugin". What could plugins provide ?
|
|
****** commands - for all uis, or for one or more of them (cli, web, vty..). A command may itself be a new ui.
|
|
****** import/export formats
|
|
****** skins/styles/templates for uis, eg the web ui ?
|
|
**** techniques to consider
|
|
***** running executables provided by plugins
|
|
a cli command plugin: cli execs the executable with same arguments
|
|
a web command plugin: web ui runs the executable as a subprocess and captures the output

***** linking plugins into main app with direct-plugins
|
|
simplification of plugins lib
|
|
main app needs to know the types used in plugin's interface
|
|
weakens type safety, avoiding runtime errors requires extra care
|
|
requires whole-program linking at plugin load time
|
|
plugins can be discovered by querying ghc for installed packages or modules in a known part of the hierarchy
|
|
maintained and keen to help
|
|
***** linking plugins into main app with plugins (original)
|
|
more complex than above
|
|
more type-safe/featureful ?
|
|
***** doing whatever xmonad does with dyre
|
|
***** interpreting plugins under control of main app with hint
|
|
ghci in an IO-like monad
|
|
types need converting, etc.
|
|
plugins may run more slowly
|
|
plugins can be discovered/loaded by module path or by loading files directly

*** charts
|
|
[1:27pm] <sm> I have decided I am not getting enough visible day-to-day value out of my ledger, I need more of that to stay motivated
|
|
[1:27pm] <Nafai> What do you think will help in that?
|
|
[1:27pm] <sm> I think some simple self-updating charts, or even good reports in a visible place
|
|
[1:28pm] <sm> something I don't have to spend an hour fiddling with to get answers
|
|
[1:38pm] <sm> Nafai: identifying/designing some useful reports/charts seems to be blocking me
|
|
[1:39pm] <sm> there are probably some standard ones I should use
|
|
[1:40pm] <sm> a graph of daily net worth is probably one of the simplest
|
|
[1:58pm] <sm> what else.. a chart of weekly expenses in key categories
|
|
[1:58pm] <sm> ditto, monthly
|
|
[1:58pm] <sm> a chart of monthly income
|
|
[1:59pm] <sm> those three should help me be more clear about cashflow status
|
|
[2:00pm] <sm> also I'd like something that shows me how much I am on top of financial tracking - how current my numbers are, when last reconciled etc - at a glance
|
|
[2:01pm] <sm> another simple one: current balances in all accounts
|
|
[2:01pm] <sm> those would be a great start
|
|
[2:04pm] <sm> daily net worth, weekly expense, monthly expense, monthly income, confidence/currentness report, and balance report
|
|
[2:05pm] <sm> let's see, which of those 6 would give most payoff right now
|
|
[2:05pm] <sm> probably 5
|
|
[2:06pm] <sm> how could I measure that ?
|
|
[2:06pm] <sm> number of days since last ledger entry..
|
|
[2:06pm] <sm> number of ledger entries in last 30 days (compared to average)
|
|
[2:07pm] <sm> number of days since last cleared checking entry (indicating an online reconcile)
|
|
[2:08pm] <sm> those would be a good start. How do I make those visual
|
|
[2:09pm] <sm> well I guess the first step is a script to print them

*** ledger budgeting/forecasting
|
|
seanh:
|
|
|
|
With `--budget` you can compare your budgeted transactions to your
|
|
actual transactions and see whether you are under or over your budget.
|
|
|
|
The way it works is this: say you have a budget entry that moves £50
|
|
from Assets into Expenses:Cash every week:
|
|
|
|
~ Weekly
|
|
Expenses:Cash £50
|
|
Assets
|
|
|
|
When you run register or balance with `--budget` ledger will insert
|
|
reverse transactions that move £50 _from_ Expenses:Cash _into_ Assets
|
|
every week. These are called budget entries. The idea is that your real
|
|
transactions that move money from Assets into Expenses will offset the
|
|
inserted budget entries that move money the other way. The budget
|
|
entries and the real transactions should sum to zero, if they don't then
|
|
it shows how much you have overspent or underspent.
|
|
|
|
For example:
|
|
|
|
ledger --budget balance '^expenses'
|
|
|
|
balances your budgeted expenses against your actual expenses on those
|
|
budgeted accounts (sub-accounts of expenses that do not appear in the
|
|
budget are ignored in this calculation). The sum of the budget entries
|
|
(which move money out of expenses accounts) and your real transactions
|
|
(which move money into expenses accounts) should be 0. If the sum is
|
|
positive then it shows how much you've overspent, if it's negative then
|
|
it shows how much you've underspent.
|
|
|
|
You can do the same with register and get a print out of each
|
|
transaction (budget entries and real transactions) with a running total:
|
|
|
|
ledger --budget register '^expenses'
|
|
|
|
And you can produce weekly, monthly or yearly budget reports:
|
|
|
|
ledger --budget --weekly register '^expenses'
|
|
ledger --budget --monthly register '^expenses'
|
|
ledger --budget --yearly register '^expenses'
|
|
|
|
These will only output reports for each week, month or year that has
|
|
passed (your ledger file contains transactions dated later than that
|
|
week, month, or year). You can see how well you did last week (or month,
|
|
or year) but you can't see how well you're doing so far this week
|
|
(month, year).
|
|
|
|
The `--unbudgeted` argument will show (and sum) all your expenses for
|
|
accounts that are _not_ budgeted, and the `--add-budget` argument will
|
|
consider all your expenses budgeted or not with the budget entries
|
|
added in.
|
|
|
|
With `--forecast` you can project your budget into the future to see,
|
|
for example, when some account will reach 0. For example, to predict
|
|
your net worth:
|
|
|
|
ledger --forecast 'd<[2012]' register '^assets' '^liabilities'
|
|
|
|
Or to see how your expenses will add up:
|
|
|
|
ledger --forecast 'd<[2012]' register '^expenses'
|
|
|
|
*** essential/getting started info
|
|
|
|
I've never used financial management software before, I'm just confused at what I'm doing.
|
|
http://en.wikipedia.org/wiki/Double-entry_bookkeeping_system
|
|
money isn't created or destroyed, it moves between accounts
|
|
all possible accounts are organised under five categories: assets, liabilities, equity, income, expenses
|
|
|
|
the gist of it for *ledger users is that each transaction in your journal (file) is balanced, ie its postings add up to zero
|
|
typically you have a posting to some account (expenses:food $10) and an equal posting from another (assets:cash $-10)
|
|
|
|
so should things like income be a forever-decreasing value?
|
|
yes
|
|
|
|
I think traditional bookkeeping uses "debit" and "credit" for (among other things) hiding the negative sign
|
|
I wonder, if folks had been comfortable with negative numbers in the middle ages, if debit/credit would have been invented
|
|
|
|
so, when I start a ledger file and I start my initial account balances for, say, checking, I withdraw them from equity or income? Or does it matter in this case?
|
|
traditionally, you transfer opening balances from equity
|
|
and this is just a convention, or is there some better reason behind it?
|
|
I believe it's actually based on the real-world meaning, and makes sense if you study enough bookkeeping
|
|
I thought equity was more a share of something owned.
|
|
that's right, and if you squint enough the two uses are equivalent
|
|
So I'd do something like "assets:checking $foo \ assets:savings $bar \ liabilities:creditcard $-baz \ equity:opening balance"?
|
|
yes
|
|
|
|
what about loans? Those are liabilities, right?
|
|
yes
|
|
|
|
okay. So after I set up my initial account balances, it's just a matter of keeping track how and what I spend.
|
|
yup, tracking your checking account's or your wallet's inflows and outflows is a good way to start
|
|
Gradually you'll add more tricky things like invoices and short-term loans (accounts receivable/payable)
|
|
|
|
|
|
I also read in the manual that you can set up routine actions, like debiting from one account and crediting to another on a monthly basis.
|
|
this can help me set up budgets, right?
|
|
yes, ledger lets you specify those with special modifier/periodic transactions. They appear in reports but not in your journal file. Or you can use cron or something to actually add them to the journal
|
|
and there's also a budget report feature
|
|
|
|
a catalog of standard bookkeeping entries for typical real-world transactions is really helpful and worth searching for

** hledger feedback
|
|
*** fabrice niessen
|
|
+For me, what would be very useful for a 1.0 version would be:
|
|
+
|
|
+- @check directive (see beancount), but implemented as a comment for ledger,
|
|
+ so that ledger does not get confused by this, and that you can implement
|
|
+ more features without breaking backward compatibility;
|
|
+
|
|
+- account declaration (see beancount), in ledger comments. Giving an account
|
|
+ number would (or could) help for the reporting stuff, for knowing which
|
|
+ value to get to read, for inserting in a given report;
|
|
+
|
|
+- some built-in ratios for being able to see the health of the finances (see
|
|
+ my Excel file, if you're interested);
|
|
+
|
|
+- easier standard outputs, such as the one above (with expenses and income in
|
|
+ 2 columns).
|
|
+
|
|
+- real report generation (I thought at LaTeX as in SQL Ledger, but I am now
|
|
+ heading and producing reports through Org, which is 1000x better). Results
|
|
+ soon.

** hamlet feedback
|
|
*** thread data through nested templates with Reader monad
|
|
*** HDString constructor for HamletData ?
|
|
*** data type for non-RT Hamlet as well, or better, the same type for both
|
|
*** allow (RT or non-RT) templates in $ $ as well, drop ^ ^
|
|
*** allow literal arguments in references
|
|
*** easier verbatim content quoting, eg lines starting with \\. Having to escape $$ is not so convenient for jquery
|
|
*** docs and compiler errors should say something clearer than "Hamlet url" (Hamlet routetype, urltype, routet, urlt ?)
|
|
|
|
|
|
*** 2010/8
|
|
**** $ $ could handle templates as well; drop ^ ^
|
|
**** @ @ could recognise tuples automatically; drop ?
|
|
**** why !: : for conditional attributes ? How about !? ?
