hledger project notes

about

This emacs org-mode outline contains Simon's project backlog, activity log, and random developer notes. Currently only I use this file, but anyone can send a patch.

backlog

Todos and wishlist items, roughly grouped by category and ordered by (my) priority. Used for planning, and often as a more lightweight bug tracker. Also contains..

estimates

I keep effort-to-complete estimates on backlog tasks as N[dwm] at the end of the line following two spaces, meaning N hours, days, weeks or months, assuming 4 hours in day, 5 days in a week, and 4 weeks in a month.

burndown charts

At some point there might be a process to aggregate estimates, log them (including deleted items as 0) on commit, and make burndown charts.

routines

standard procedures/checklists for various activities

things I want to know about money and time

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 ?

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

This is the main object you'll deal with as a user of the Ledger library.

The most useful functions also have shorter, lower-case aliases for easier interaction. Here's an example:

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.

Martin Wuertele, debian:

I see our task not in keeping accounts (that's in the responsibility of the trusted bodies) but more in management accounts. In order to achieve that we need a solution that mirrors the financials of the trusted bodies, has a way to streamline them (allign different local chart of accounts or reporting formats to an unified one), do some reclassifications and accruals on top, performe currency conversions (we have debian.uk, debian.ch, FFIS, SPI-INC,…), accumulate the results, add additional reclassifications and accruals on top and, in some cases, add consolidation entries (e.g. SPI-INC does reembursement but gets itself reembursed by FFIS).

We do not bother with any local tasks like income tax, vat or statistical filing, invoicing and the like.

my 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 !? ?

Usage: hledger [OPTIONS] COMMAND [PATTERNS] hledger [OPTIONS] convert CSVFILE

Reads your ~/.journal file, or another specified by $LEDGER or -f, and runs the specified command (may be abbreviated):

add - prompt for new transactions and add them to the journal balance - show accounts, with balances convert - show the specified CSV file as a hledger journal histogram - show a barchart of transactions per day or other interval print - show transactions in journal format register - show transactions as a register with running balance stats - show various statistics for a journal test - run self-tests

hledger options: -f FILE file=FILE use a different journal/timelog file; - means stdin no-new-accounts don't allow to create new accounts -b DATE begin=DATE report on transactions on or after this date -e DATE end=DATE report on transactions before this date -p EXPR period=EXPR report on transactions during the specified period and/or with the specified reporting interval -C cleared report only on cleared transactions -U uncleared report only on uncleared transactions -B cost, basis report cost of commodities depth=N hide accounts/transactions deeper than this -d EXPR display=EXPR show only transactions matching EXPR (where EXPR is 'dOP[DATE]' and OP is <, <=, , >, >) effective use transactions' effective dates, if any -E empty show empty/zero things which are normally elided -R real report only on real (non-virtual) transactions flat balance: show full account names, unindented drop=N balance: with flat, elide first N account name components no-total balance: hide the final total -D daily register, stats: report by day -W weekly register, stats: report by week -M monthly register, stats: report by month -Q quarterly register, stats: report by quarter -Y yearly register, stats: report by year -v verbose show more verbose output debug show extra debug output; implies verbose binary-filename show the download filename for this hledger build -V version show version information -h help show command-line usage

DATES can be y/m/d or smart dates like "last month". PATTERNS are regular expressions which filter by account name. Prefix a pattern with desc: to filter by transaction description instead, prefix with not: to negate it. When using both, not: comes last.

short description

collect/clarify

hledger is a robust command-line accounting tool with a simple plain text data format.

hledger is a reporting tool for accounting transactions stored in a simple human-editable text format.

hledger is a computer program for easily tracking money, time, or other transactions, usually recorded in a general journal file with a simple human-editable markup format.

hledger is primarily a reporting tool, but it can also help you add transactions to the journal, or convert from other data formats.

hledger is a haskell port and friendly fork of John Wiegley's c++ ledger tool.

hledger aims to be a reliable, practical, useful tool for (slightly geeky) users and a reusable library for haskell programmers interested in finance.

hledger is quite simple in essence, aiming to be a reliable low-level parsing-and-reporting tool that doesn't get in your way.

For some, it is a less complex, less expensive, more efficient alternative to Quicken or Quickbooks.

hledger is available for free under the GNU General Public License.

hledger reads plain text files (general journal, timelog, or CSV format) describing transactions (in money, time or other commodities) and prints the chart of accounts, account balances, or transactions you're interested in.

hledger is a free program that helps you understand your finances, making calculations based on data stored a simple text file. If you prefer the command line and a text editor to a big gui application, hledger gives you the power of Quicken and Quickbooks without the complexity.

Your financial data will outlive your financial software, so it should have longevity and accessibility. Its integrity is important to your peace of mind, so changes should be transparent and (if desired) version controlled. It may also be important to allow multiple authors to edit safely. A structured, easy-to-parse, human-friendly plain text format, as in the wiki world, provides a good balance of longevity, reliability, transparency and flexibility.

hledger helps you track and understand your finances, making calculations based on data stored in a simple text file. If you prefer the command line and a text editor to a big gui application, hledger gives you the power of Quicken and Quickbooks without the complexity.

Features: reads transactions in journal, timelog, or CSV format; handles multi-currency/multi-commodity transactions; prints the chart of accounts, account balances, or transactions you're interested in, quickly; scriptable.

hledger is written in the Haskell programming language; it demonstrates a pure functional implementation of ledger.

life cycle of top-level accounts

For personal ledgers, when you're born, all accounts are at zero (one hopes) and as you live:

  1. Equity accounts accommodate your previous years of not maintaining accounts (fixed, probably negative)
  2. Expense accounts become more and more positive (unavoidably)
  3. Income accounts become more and more negative (on payday)
  4. Assets Accounts become more and more positive (in good times)
  5. Liability account become more positive (in good times, when you pay them off) and more negative (when you use them to buy things).

When you die, Equity: and Income: will stand at large negative balances, Expense: and Assets: will stand at large positive balances and Liabilities will have to be paid (out of Assets) before your heirs get what's left.

testing

hledger's unit tests and a simple test runner are built in. They can be run several ways:

$ hledger test [PAT] $ make unittest $ make autotest

They can also be built as a separate executable, in case needed for cabal test. (?) This requires test-framework, which may not work on windows.

$ make unittest-standalone

hledger's functional tests are a set of @shelltestrunner@ tests defined by .test files in the tests\/ subdirectory.

$ make functest

Shell tests can also be defined as doctests, literal blocks embedded in modules' haddock docs, though this is hardly used. For example:

@ $ bin\/hledger -f data\/sample.journal balance o $1 expenses:food $-2 income $-1 gifts $-1 salary


$-1 @

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)

competitors/fellow niche inhabitants ==================================

  • web apps

    • netsuite
    • sql-ledger, ledgersmb
    • wesabe
  • desktop apps

    • quickbooks
    • quicken
    • ms money
    • grisbi
    • gnucash
    • excel
    • ledger!

most haskellers have never heard of hledger, sounds arrogant or hubristic to talk of charging for it

real-time project ledger
in-place transaction editing fund drive

Fund drive: hledger-web in-place transaction editing

Goal: I would like to raise $X or more to fund basic in-place transaction editing for hledger-web. hledger-web is a web-based GUI for hledger (and ledger), which are free/open-source accounting programs providing a lean and efficient alternative to quicken, gnucash, mint.com etc.

Current hledger-web[1] has simple web forms for adding transactions and for editing the whole journal, but there is no easy ui for editing a single existing transaction. Such a ui is an important step towards making hledger (and ledger) usable by non techies, which would greatly expand these tools' applicability and potential user/contributor base.

Plan: do the front-end javascript and backend haskell work required to support:

  • click date, description, account or amount cells in a register view to make that cell editable
  • tab moves to the next cell
  • enter or click on save button updates the transaction in the journal, overwriting/rewriting the whole file
  • tested in firefox/chrome/safari

The proposed amount will fund about 10 hours of work, so the above features must be implemented very expeditiously. Other improvements will be tackled in a followup fund drive if this one succeeds (or in this one if the funding goal is exceeded.) Those future items include:

  • history/content awareness, smart defaults and auto-completion wherever useful
  • date picker widget
  • ability to add/remove postings
  • ability to edit metadata/tags
  • ability to edit other transaction/posting fields
  • ledger compatibility
  • compatibility testing/fixes for all the major browsers
  • edit conflict checking - don't overwrite concurrent external edits
  • try harder to preserve existing file layout/co-exist better with external edits
  • a similar ui for adding new transactions
  • pleasant visual style

Also, 10% of the amount raised will be tithed to three contributing projects or developers (ledger and two others of my choice.)

This project will go forward if

stop on first failure
run tests in bottom up order

envision better test setup

every parser has a test and is easy to test
easy to run any single test or module's tests
tests run bottom up by default
test runner can select tests precisely eg by regexp
test runner stops at first failure by default

I had a question about balance totals. Given this test data:

$ cat test.dat D $1,000.00 P 2011-01-01 22:00:00-0800 TESTA $78.35 P 2011-01-01 22:00:00-0800 TESTB $15.86 P 2011-01-01 22:00:09-0800 TESTC $13.01

I'm a little bit surprised that the sub-accounts reflect a difference from the top level account w/re to rounding the last cent:

$ ledger -V -f test.dat bal $48,527.27 Assets:Brokerage $14,763.02 TESTA $28,695.21 TESTB $5,069.03 TESTC $-47,728.14 Equity:Opening Balances


$799.13

Even if no-rounding is passed in:

$ ledger -V -f test.dat --no-rounding bal $48,527.27 Assets:Brokerage $14,763.02 TESTA $28,695.21 TESTB $5,069.03 TESTC $-47,728.14 Equity:Opening Balances


$799.13

Is there something off with how the data aboce is set up? Should I be using be more place holders?

cli, web: consistent query language with grouping and nesting

ledger's query syntax: http://ledger-cli.org/3.0/doc/ledger.1.html

draft 1:

Filter patterns restrict the postings/transactions that are displayed. (They often reduce the amount of processing work hledger has to do, as well.) A pattern is a string or regular expression, usually with a prefix specifying the type of match to do. The supported prefixes are:

acct:PAT match postings affecting accounts whose name matches PAT otheracct:PAT match the other postings in transactions with an acct match (like ledger's related) anyacct:PAT match all postings in transactions with an acct match (union of acct and otheracct) desc:PAT match postings whose description matches PAT status:PAT match postings whose cleared status matches PAT code:PAT match postings whose transaction code matches PAT tag:PAT match postings with a metadata tag whose name matches PAT tag:TAG=PAT match postings with a metadata tag named TAG whose value matches PAT from:DATE match postings on or after DATE (like begin) to:DATE match postings before DATE (like end) in:PERIOD match postings during PERIOD (like period) (or ? begin:DATE match postings on or after DATE (like begin) end:DATE match postings before DATE (like end) period:PERIOD match postings during PERIOD (like period) )

Prefixes have a short form which is their first letter, except for tag and anyacct.

Prefix-less patterns are treated like acct: patterns, except by the register command which treats them as otheracct: .

Patterns containing whitespace must be enclosed in quotes.

Matches are always case-insensitive.

Matches are always substring matches (except for TAG); to match exactly, wrap the pattern in ^ and $.

A posting's date, status, code, etc. is usually (but not always) that of its containing transaction.

Any of these may be further prefixed with not: for an inverse match.

Filter patterns may be combined with AND, OR, and parentheses. OR is assumed by default. (previously: When you specify multiple filter patterns, hledger generally selects the items which match:

any of the account patterns AND any of the description patterns

The print command selects transactions which

match any of the description patterns AND have any postings matching any of the positive account patterns AND have no postings matching any of the negative account patterns )

Thomas, I didn't see your reply because I'm not subscribed to this Google Group. I believe that QuickBooks uses OFX, not QIF, so you'd be more interested in

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 semi/automatically submit parse error reports when they happen

parsing: alias directives should be modified by account directives

parsing: allow price record for null commodity, eg with quotes

parsing: canonicalise account names to be case-insensitive ?

parsing: end directive may also be spelled end account; or end ends last directive

parsing: enforce positive price amounts, like ledger

eg 1€ @@ $-2 is not allowed

parsing: ignore/support all ledger assert directives ?

; Assertion directives Options ; These can occur in many places: ; ; ; Within an automated transaction, the assert is evaluated every time ; ; a posting is matched, with the expression context set to the ; ; matched posting. ; = Food ; assert account("Expenses:Food").total >= $100 ; 2010-06-12 Sample ; Expenses:Food $100 ; Assets:Checking ; ; ; At file scope, the expression is evaluated within "global" scope. ; assert account("Expenses:Food").total == $100 ; ; ; At the top of a transction, the assertion's scope is the ; ; transaction. After a posting, the scope is that posting. Note ; ; however that account totals are only adjusted after successful ; ; parsing of a transaction, which means that all the assertions below ; ; are true, even though it appears as though the first posting should ; ; affect the total immediately, which is not the case. ; 2010-06-12 Sample 2 ; assert account("Expenses:Food").total == $100 ; Expenses:Food $50 ; assert account("Expenses:Food").total == $100 ; Assets:Checking ; assert account("Expenses:Food").total == $100

parsing: more date syntax ? last nov, next friday, optional this, week of

parsing: more flexible file including

currently only journals (not timelog files) can include, and only another journal

parsing: more period syntax ? every N days, biweekly

parsing: parse YNAB export

$ tail -n +2 YNAB/Exports/personal-Register.csv | hledger -f- print --rules-file YNAB/Exports/personal-Register.rules using conversion rules file /Users/simon/personal/YNAB/Exports/personal-Register.rules hledger: using amount-in-field and amount-out-field, found a value in both fiel ds: ("$0.00","$4.68")

parsing: per-posting effective/actual dates

parsing: period expressions should allow interval at the end

eg support -p 'from 1/1 to 2/1 weekly'

parsing: safety check that effective date > actual (to catch eg 2009/12/30=1/4)

parsing: support apostrophe digit group separator

print: shouldn't support -M and depth ?

register: for the love of god, show full descriptions

balance setting

ledger: You can accomplish "setting to the bank's view" with a transaction like this:

2011-08-12 Sample Assets:Checking = $200.00 Equity:Adjustments

This tells Ledger (Git/3.0) that your checking account's balance must be $200 after this transaction is completed. It will put whatever amounts are required to accomplish this into the Equity:Adjustments account.

what about balance assertions ?

clear, documented interfaces

client-side ui

debug logging

detect .hs plugins

don't recompile between autotest & functest

Double -> Decimal

query by commodity

generalise rules file ?

make it applicable to all formats ?
absorb its directives into journal format ?

nice standard financial reports

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

runtime report templates

separate display and limit expressions, eg for depth

perf: more speed, memory optimisation

support - in period expressions

support -V ?

talkback feature

gather data on real-world installation & usage issues simplify bug reporting/handling improve reliability

upload feature
