## About the project
### Mission
Why was hledger created ?
Mainly:
- to provide a more usable, robust, documented, cross-platform-installable version of Ledger for users
- to provide a more maintainable and hackable version of Ledger for developers
Also:
- to provide a useful library and toolbox for finance-minded haskell programmers
- to explore the suitability of Haskell for such applications
- to experiment with building a successful time-and-money-solvent project in a thriving ecosystem of financial software projects
What is the hledger project's current mission ?
1. Provide peace of mind: bring clarity, relief, and peace of mind to folks stressed, confused, overwhelmed by finances.
2. Educate and empower: help individuals and communities achieve clarity, accountability and mastery with money and time.

### Developer
See [Developer workflows](#developer-workflows).
## Make
A Makefile is provided to make common developer tasks easy to remember,
and to insulate us a little from the ever-evolving Haskell tools ecosystem.
Using it is entirely optional, but recommended.
You'll need [GNU Make](https://www.gnu.org/software/make) installed.
The Makefile contains a fair amount of obsolete cruft and needs cleanup. Some tasks (docs, website) are now handled by the [Shake](#shake) file instead.
The Makefile is self-documenting. Run `make` to see a list of the main make rules:
```shell
$ make
Makefile:37: -------------------- hledger make rules --------------------
Makefile:39: make [help] -- list documented rules in this makefile. make -n RULE shows more detail.
Makefile:204: (INSTALLING:)
Makefile:206: make install -- download dependencies and install hledger executables to ~/.local/bin or equivalent (with stack)
Makefile:231: (BUILDING:)
Makefile:235: make build -- download dependencies and build hledger executables (with stack)
Makefile:304: make hledgerdev -- quickly build the hledger executable (with ghc and -DDEVELOPMENT)
...
```
To see what a make rule will do without actually doing it, use the `-n` flag:
```shell
$ make build -n
stack build
```
```shell
$ make test -n
(stack test \
&& echo pkgtest PASSED) || echo pkgtest FAILED
(stack exec hledger test \
&& echo builtintest PASSED) || echo builtintest FAILED
(COLUMNS=80 PATH=`pwd`/bin:/home/simon/src/hledger/bin:/home/simon/.local/bin:/home/simon/.cabal/bin:/opt/ghc/7.10.1/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/var/lib/gems/1.9.1/bin stack exec -- shelltest --execdir -- -j16 --hide-successes tests \
&& echo functest PASSED) || echo functest FAILED
```
## Shake
`Shake.hs` in the top directory complements the Makefile; it is used for some more complex tasks, such as building documentation and the web site.
Compile it:
./Shake.hs # or, make Shake
See help:
./Shake
## Code
hledger is a suite of applications, tools and libraries.
The main hledger code repository is [github.com/simonmichael/hledger](https://github.com/simonmichael/hledger)
(shortcut url `code.hledger.org`).
There are also various hledger addons maintained as separate projects with their own repos.
### hledger packages
Within the main repo, there are a number of separate cabal packages,
making it easier to pick and choose parts of hledger to install or to package.
They are:
#### hledger-lib
[package](https://hackage.haskell.org/package/hledger-lib),
[code](https://github.com/simonmichael/hledger/tree/master/hledger-lib)
Core data models, parsing, standard reports, and utilities.
Most data types are defined in [Hledger.Data.Types](https://hackage.haskell.org/package/hledger-lib/docs/Hledger-Data-Types.html),
while functions that operate on them are defined in Hledger.Data.TYPENAME.
Under [Hledger.Read](https://github.com/simonmichael/hledger/tree/master/hledger-lib/Hledger/Read.hs)
are parsers for the supported input formats.
Data files are parsed into a
[Journal](https://hackage.haskell.org/package/hledger-lib/docs/Hledger-Data-Types.html#t:Journal),
which contains a list of
[Transactions](https://hackage.haskell.org/package/hledger-lib/docs/Hledger-Data-Types.html#t:Transaction),
each containing multiple
[Postings](https://hackage.haskell.org/package/hledger-lib/docs/Hledger-Data-Types.html#t:Posting)
of some
[MixedAmount](https://hackage.haskell.org/package/hledger-lib/docs/Hledger-Data-Types.html#t:MixedAmount)
(multiple
single-[CommoditySymbol](https://hackage.haskell.org/package/hledger-lib/docs/Hledger-Data-Types.html#t:CommoditySymbol)
[Amounts](https://hackage.haskell.org/package/hledger-lib/docs/Hledger-Data-Types.html#t:Amount))
to some
[AccountName](https://hackage.haskell.org/package/hledger-lib/docs/Hledger-Data-Types.html#t:AccountName).
When needed, the Journal is further processed to derive a
[Ledger](https://hackage.haskell.org/package/hledger-lib/docs/Hledger-Data-Types.html#t:Ledger),
which contains summed
[Accounts](https://hackage.haskell.org/package/hledger-lib/docs/Hledger-Data-Types.html#t:Account).
In [Hledger.Reports](https://hackage.haskell.org/package/hledger-lib/docs/Hledger-Reports.html)
there are standard reports, which extract useful data from the Journal or Ledger.
Here's a diagram of the main data model:

#### hledger
[package](https://hackage.haskell.org/package/hledger),
[code](https://github.com/simonmichael/hledger/tree/master/hledger),
[manual](https://hledger.org/hledger.html)
hledger's command line interface, and command line options and utilities for other hledger tools.
Try tracing the execution of a hledger command:
1. [Hledger.Cli.Main:main](https://github.com/simonmichael/hledger/blob/master/hledger/Hledger/Cli/Main.hs#L302)
parses the command line to select a command, then
2. gives it to
[Hledger.Cli.Utils:withJournalDo](https://github.com/simonmichael/hledger/blob/master/hledger/Hledger/Cli/Utils.hs#L73),
which runs it after doing all the initial parsing.
3. Parsing code is under
[hledger-lib:Hledger.Read](https://github.com/simonmichael/hledger/tree/master/hledger-lib/Hledger/Read.hs),
eg [Hledger.Read.JournalReader](https://github.com/simonmichael/hledger/tree/master/hledger-lib/Hledger/Read/JournalReader.hs).
4. Commands extract useful information from the parsed data model using
[hledger-lib:Hledger.Reports](https://github.com/simonmichael/hledger/tree/master/hledger-lib/Hledger/Reports),
and
5. render in plain text for console output (or another output format, like CSV).
6. Everything uses the data types and utilities from
[hledger-lib:Hledger.Data](https://github.com/simonmichael/hledger/tree/master/hledger-lib/Hledger/Data)
and [hledger-lib:Hledger.Utils](https://github.com/simonmichael/hledger/blob/master/hledger-lib/Hledger/Utils.hs).
#### hledger-ui
[package](https://hackage.haskell.org/package/hledger-ui),
[code](https://github.com/simonmichael/hledger/tree/master/hledger-ui),
[manual](https://hledger.org/hledger-ui.html)
A terminal interface.
#### hledger-web
[package](https://hackage.haskell.org/package/hledger-web),
[code](https://github.com/simonmichael/hledger/tree/master/hledger-web),
[manual](https://hledger.org/hledger-web.html)
A web interface.
hledger-web starts a web server built with the yesod framework,
and (by default) opens a web browser view on it.
It reads the journal file(s) at startup and again whenever they change.
It can also write (append) new transactions to the journal file.
There are two main views, which can be filtered with
[queries](https://hledger.org/hledger.html#queries):
- [/journal](https://demo.hledger.org/journal), showing general journal entries (like `hledger print`)
- [/register](https://demo.hledger.org/register?q=inacct:Expenses:Food),
showing transactions affecting an account (slightly different from
hledger's [register](https://hledger.org/hledger.html#register) command, which shows postings).
There is also:
- a sidebar (toggled by pressing `s`) showing the chart of accounts (like `hledger balance`)
- an [add form](https://demo.hledger.org/journal?add=1) for adding new transactions (press `a`)
- a help dialog showing quick help and keybindings (press `h` or click ?)
Most of the action is in
- [config/routes](https://github.com/simonmichael/hledger/tree/master/hledger-web/config/routes)
- [templates/default-layout-wrapper.hamlet](https://github.com/simonmichael/hledger/tree/master/hledger-web/templates/default-layout-wrapper.hamlet)
- [Foundation](https://github.com/simonmichael/hledger/tree/master/hledger-web/Foundation.hs)
- [Handler.*](https://github.com/simonmichael/hledger/tree/master/hledger-web/Handler)
- [static/hledger.js](https://github.com/simonmichael/hledger/tree/master/hledger-web/static/hledger.js)
- [static/hledger.css](https://github.com/simonmichael/hledger/tree/master/hledger-web/static/hledger.css)
Handler module and function names end with R, like the yesod-generated route type they deal with.
Dynamically generated page content is mostly inline hamlet.
Lucius/Julius files and widgets generally are not used, except for the default layout.
Here are some ways to run it during development:
- `yesod devel`: runs in developer mode, rebuilds automatically when config, template, static or haskell files change
(but only files in the hledger-web package):
```shell
$ (cd hledger-web; yesod devel)
```
- [yesod-fast-devel](https://hackage.haskell.org/package/yesod-fast-devel)
may be a good alternative, also reloads the browser page
- `stack ghci`: runs the server in developer mode from GHCI.
Changes to static files like hledger.js will be visible on page reload;
to see other changes, restart it as shown.
```shell
$ (cd hledger-web; stack ghci hledger-web)
hledger-web> :main --serve # restart: ctrl-c, :r, enter, ctrl-p, ctrl-p, enter
```
- `make ghci-web`: runs the server in developer mode from GHCI, also
interprets the hledger-lib and hledger packages so that :reload picks
up changes in those packages too:
```shell
$ make ghci-web
ghci> :main --serve
```
(This rule also creates symbolic links to hledger-web's `config`, `messages`, `static` and `templates`
directories, needed in developer mode, so it can run from the top directory. This may not work on Windows.)
### Quality
Relevant tools include:
- unit tests (HUnit, make unittest)
- functional tests (shelltestrunner, make functest)
- performance tests (simplebench, make bench)
- documentation tests (make haddocktest + manual)
- ui tests (manual)
- installation tests (manual)
- code reviews

## Tests
About testing in the hledger project, as of 201809.
### Kinds of tests
<div style="margin:1em 2em; font-style:italic;">
"Here, then, is a list of properties of tests. Not all tests need to exhibit all properties. However, no property should be given up without receiving a property of greater value in return.
- Isolated — tests should return the same results regardless of the order in which they are run.
- Composable — if tests are isolated, then I can run 1 or 10 or 100 or 1,000,000 and get the same results.
- Fast — tests should run quickly.
- Inspiring — passing the tests should inspire confidence
- Writable — tests should be cheap to write relative to the cost of the code being tested.
- Readable — tests should be comprehensible for reader, invoking the motivation for writing this particular test.
- Behavioral — tests should be sensitive to changes in the behavior of the code under test. If the behavior changes, the test result should change.
- Structure-insensitive — tests should not change their result if the structure of the code changes.
- Automated — tests should run without human intervention.
- Specific — if a test fails, the cause of the failure should be obvious.
- Deterministic — if nothing changes, the test result shouldn’t change.
- Predictive — if the tests all pass, then the code under test should be suitable for production."
--[Kent Beck](https://medium.com/@kentbeck_7670/test-desiderata-94150638a4b3)
</div>
1. Unit tests
Unit tests exercise small chunks of functionality. In hledger, that
means a function. So, many of our functions have one or more unit
tests. These are mostly in hledger-lib, with a few in hledger.
Our unit tests use the
[tasty](https://hackage.haskell.org/package/tasty) test runner,
[tasty-hunit](https://hackage.haskell.org/package/tasty-hunit) HUnit-style tests,
and some helpers from
[Hledger.Utils.Test](https://github.com/simonmichael/hledger/blob/master/hledger-lib/Hledger/Utils/Test.hs),
such as:
- `tests` and `test` aliases for `testGroup` and `testCase`
- `assert*` helpers for constructing various kinds of assertions
We would like our unit tests to be:
- easy to read (clear, concise)
- easy to write (low boilerplate, low cognitive load)
- easy to maintain (easy to edit, easy to refactor, robust)
- easy to associate with the code under test (easy to view/jump
between code & test, easy to estimate coverage)
- and scalable (usable for all devs, easy to run and select,
suitable for small/large modules/packages).
Here\'s the current pattern (let us know if you see a better way):
``` haskell
module Foo (
...
tests_Foo -- export this module's and submodules' tests
)
where
import Hledger -- provides Hledger.Utils.Test helpers
import Bar -- submodules, providing tests_Bar etc.
import Baz
functionA = ...
functionB = ...
functionC = ...
functionD = ...
tests_Foo = tests "Foo" [ -- define tests at the end of each module
-- a group of several named tests for functionA
tests "functionA" [
test "a basic test" $ assertBool "" SOMEBOOL
,test "a pretty equality test" $ SOMEEXPR @?= EXPECTEDVALUE
,test "a pretty parsing test" $ assertParseEq PARSER INPUT EXPECTEDRESULT
,test "a multiple assertions test" $ do
A @?= B
doSomeIO
C @?= D
]
-- a single test containing multiple unnamed assertions for functionB
,test "functionB" $ do
assertBool "" BOOL
EXPR @?= VALUE
,tests_Foo -- aggregate submodule tests
,tests_Bar
]
```
Here are
[some](https://github.com/simonmichael/hledger/blob/master/hledger-lib/Hledger/Data/Posting.hs#L296)
real-world
[examples](https://github.com/simonmichael/hledger/blob/master/hledger-lib/Hledger/Read/JournalReader.hs#L579).
The unit tests are shipped as part of the hledger executable, and
can always be run via the [test](https://hledger.org/manual#test)
command (`hledger test`).
Here\'s the quick way to run unit tests while developing:\
`make ghcid-test` or `make ghcid-test-Some.Module`.
2. Doc tests
Like unit tests, but defined inside functions\' haddock
documentation, in the style of a GHCI transcript. These test
functionality, provide usage examples in the API docs, and test
those examples, all at once. They are a bit more finicky and slower
than unit tests. See
[doctest](https://hackage.haskell.org/package/doctest) for more.
doctests [do not work on Mac with GHC
8.4+](https://github.com/sol/doctest/issues/199), out of the box.
See
[ghc\#15105](https://ghc.haskell.org/trac/ghc/ticket/15105#comment:10)
for current status and a workaround.
3. Functional tests
Functional tests test the overall functioning of the program. For
hledger, that means running `hledger` with various inputs and
options and checking for the expected output. This exercises
functionality in the hledger and hledger-lib packages. We do this
with
[shelltestrunner](https://hackage.haskell.org/package/shelltestrunner).
Tests are defined in files named `*.test` under
[hledger/test/](https://github.com/simonmichael/hledger/tree/master/hledger/test),
grouped by *component* (command or topic name).
For more about these, see the README there.
4. Code tests
We have some tests aimed at testing eg code quality, generally
defined as make rules, such as:
--------------------- -------------------------------------------------------------------------------------
`make haddocktest` can haddock process all code docs without error
`make buildtest` does all code build warning free with the default GHC version & stackage snapshot
`make buildtestall` does the code build warning free with all supported GHC versions/stackage snapshots
--------------------- -------------------------------------------------------------------------------------
See below for examples.
5. Package test suites
Haskell tools like stack and cabal recognise test suites defined in
a package\'s cabal file (or package.yaml file). These can be run via
`stack test`, `cabal test` etc., and they are required to build and
pass by services like Stackage. Here are the currently hledger
package test suites:
------------- ------------ ---------------------------------------------------------------
package test suite what it runs
hledger-lib doctests doctests
hledger-lib easytests unit tests
hledger test builtin test command (hledger\'s + hledger-lib\'s unit tests)
hledger-ui
hledger-web
------------- ------------ ---------------------------------------------------------------
### Coverage
This means how thoroughly the code is tested - both in breadth (are all
parts of the code tested at least a little ?) and in depth (are all
possible code paths, states, situations tested ?).
Our current test coverage can be summarised like so:
------------- ------ ----- ------------
package unit doc functional
hledger-lib X X X
hledger X X
hledger-ui
hledger-web
------------- ------ ----- ------------
There are ways to generate detailed coverage reports for haskell unit
tests, at least. It would be useful to set this up for hledger.
### How to run tests
Run unit tests:
``` example
$ make unittest
```
Run doctests:
``` example
$ make doctest
```
Run functional tests (and unit tests, now):
``` example
$ stack install shelltestrunner
$ make functest
```
Run the package tests (unit tests, maybe doctests, but not functional
tests) of all or selected packages.
``` example
$ stack test [PKG]
```
Run \"default tests: package plus functional tests\":
``` example
$ make test
```
Test generation of haddock docs:
``` example
$ make haddocktest
```
Thorough test for build issues with current GHC:
``` example
$ make buildtest
```
Thorough test for build issues with all supported GHC versions:
``` example
$ make buildtestall
```
Run built-in hledger/hledger-lib unit tests via hledger command:
``` example
$ hledger test # test installed hledger
$ stack build hledger && stack exec -- hledger test # test just-built hledger
$ hledger test --help
test [TESTPATTERN] [SEED]
Run the unit tests built in to hledger-lib and hledger,
printing results on stdout and exiting with success or failure.
Tests are run in two batches: easytest-based and hunit-based tests.
If any test fails or gives an error, the exit code will be non-zero.
If a pattern argument (case sensitive) is provided, only easytests
in that scope and only hunit tests whose name contains it are run.
If a numeric second argument is provided, it will set the randomness
seed for easytests.
```
Rebuild and rerun hledger/hledger-lib unit tests via ghcid:
``` example
$ make ghcid-test
```
Rebuild and rerun only some tests via ghcid (see hledger test --help):
``` example
$ make ghcid-test-TESTPATTERN
```
See all test-related make rules:
``` example
$ make help-test
```
## Benchmarks
Benchmarks are standard performance measurements,
which we define using `bench` declarations in cabal files.
There is [one in hledger.cabal](https://github.com/simonmichael/hledger/blob/master/hledger/hledger.cabal#L228),
with related code and data files in [hledger/bench/](https://github.com/simonmichael/hledger/tree/master/hledger/bench).
To run the standard hledger benchmark, use `stack bench hledger`.
This installs haskell dependencies (but not system dependencies) and rebuilds as needed,
then runs [hledger/bench/bench.hs](https://github.com/simonmichael/hledger/blob/master/hledger/bench/bench.hs),
which by default shows quick elapsed-time measurements for several operations on a standard data file:
```shell
$ stack bench hledger
NOTE: the bench command is functionally equivalent to 'build --bench'
...
hledger-0.27: benchmarks
Running 1 benchmarks...
Benchmark bench: RUNNING...
Benchmarking hledger in /Users/simon/src/hledger/hledger with timeit

print [1.29s]
register [1.92s]
balance [0.21s]
stats [0.23s]
Total: 5.22s
Benchmark bench: FINISH
```
bench.hs has some other modes, which you can use by compiling and running it directly.
`--criterion` reports more detailed and dependable measurements, but takes longer:
```shell
$ cd hledger; stack exec -- ghc -ibench bench/bench && bench/bench --criterion
...

```
`--simplebench` shows a table of elapsed-time measurements for the commands defined in [bench/default.bench](https://github.com/simonmichael/hledger/blob/master/hledger/bench/default.bench).
It can also show the results for multiple h/ledger executables side by side, if you tweak the bench.hs code.
Unlike the other modes, it does not link with the hledger code directly, but runs the "hledger" executable found in $PATH (so ensure that's the one you intend to test).
```shell
$ cd hledger; stack exec -- ghc -ibench bench/bench && bench/bench --simplebench

+-----------------------------------------++---------+
```
bench's --simplebench mode is based on a standalone tool, [tools/simplebench.hs](https://github.com/simonmichael/hledger/blob/master/tools/simplebench.hs).
simplebench.hs is a generic benchmarker of one or more executables (specified on the command line) against one or more sets of command-line arguments (specified in a file).
It has a better command-line interface than bench.hs, so you may find it more convenient
for comparing multiple hledger versions, or hledger and ledger. Eg:
```shell
$ stack exec -- ghc tools/simplebench
[1 of 1] Compiling Main ( tools/simplebench.hs, tools/simplebench.o )
Linking tools/simplebench ...
```
```shell
$ tools/simplebench -h
tools/simplebench -h
simplebench: at least one executable needed
bench [-f testsfile] [-n iterations] [-p precision] executable1 [executable2 ...]
Run some functional tests with each of the specified executables,
where a test is "zero or more arguments supported by all executables",
and report the best execution times.
-f testsfile --testsfile=testsfile file containing tests, one per line, default: bench.tests
-n iterations --iterations=iterations number of test iterations to run, default: 2
-p precision --precision=precision show times with this precision, default: 2
-v --verbose show intermediate results
-h --help show this help
Tips:
- executables may have arguments if enclosed in quotes
- tests can be commented out with #
- results are saved in benchresults.{html,txt}
```
```shell
cd hledger; $ ../tools/simplebench -f bench/default.bench hledger ledger

```
Finally, for quick, fine-grained performance measurements when troubleshooting or optimising, I use
[dev.hs](https://github.com/simonmichael/hledger/blob/master/dev.hs).
## Version numbers
Some places version numbers appear:
- --version (and sometimes --help) output of all hledger* executables
- web manuals on hledger.org
- download page
- changelogs
- release notes
- release announcements
- hackage/stackage uris
- cabal tarball filenames
- platform-specific packages
Some old version numbering goals:
1. automation, robustness, simplicity, platform independence
2. cabal versions must be all-numeric
3. release versions can be concise (without extra .0's)
4. releases should have a corresponding VCS tag
5. development builds should have a precise version appearing in --version
6. development builds should generate cabal packages with non-confusing versions
7. there should be a way to mark builds/releases as alpha or beta
8. avoid unnecessary compiling and linking
9. minimise VCS noise and syncing issues (commits, unrecorded changes)
Current version numbering policy:
- We (should) follow <https://haskell.org/haskellwiki/Package_versioning_policy>
- The "full release version" is ma.jor.minor, where minor is 0 for a
normal release or 1..n for bugfix releases. Each component is a
natural number (can be >= 10). Eg: 1.13 major release, 1.13.1
bugfix release.
- The "release version", which we prefer to use when possible, is
just ma.jor when minor is 0. Ie elide the dot zero.
- The build version is ma.jor.minor+patches, where patches is the number
of patches applied in the current repo since the last release tag.
- `hledger --version` shows the release version or build version as
appropriate.
- Release tags in the VCS are like PKG-VERSION. Eg hledger-1.13,
- hledger-ui-1.13.1.
Current process:
- In each hledger package directory there's a `.version` file
containing its desired version number.
- After changing a `.version` file: run `./Shake setversion` to
propagate the versions to all other places in the packages where
they should appear. This is not perfect (see Shake.hs) so review and
manually adjust the proposed changes before committing. Those
places include (you can also run these rules individually):
- `PKG/package.yaml` contains the cabal package version declaration,
bounds on other hledger packages, and a CPP VERSION macro used in
`hledger/Hledger/Cli/Version.hs`. Changes in package.yaml will be
propagated to `PKG/PKG.cabal` on the next stack or Shake build, or
by `make gencabal`.
- `PKG/.version.m4` contains the _version_ macro used in documentation source files (*.m4.md). It is updated by `./Shake setversion`.
- `PKG/.date.m4` contains the _monthyear_ macro used in man pages. It is updated by `./Shake manuals`.
- At release time:
- `./Shake PKG/CHANGES.md-finalise` converts the topmost heading, if
it is an interim heading (just a commit hash), to a permanent
heading containing the version and today's date.
- for each package being released, a PKG-VERSION git tag is created.
- At major release time:
- A new snapshot of the reference docs is added to the website, by
`./Shake site/doc/VERSION/.snapshot`, and added to the links in
`site/js/site.js`.
## Sample journals
Synthetic data files like `examples/100x100x10.journal` are useful for benchmarks and testing.
The numbers describe the number of transactions, number of accounts, and maximum account depth respectively.
They are generated by [`tools/generatejournal.hs`](https://github.com/simonmichael/hledger/blob/master/tools/generatejournal.hs).
They should get built automatically as needed, if not you can use `make samplejournals`:
```shell
$ make samplejournals
ghc tools/generatejournal.hs
[1 of 1] Compiling Main ( tools/generatejournal.hs, tools/generatejournal.o )
Linking tools/generatejournal ...
tools/generatejournal 100 100 10 >examples/100x100x10.journal
tools/generatejournal 1000 1000 10 >examples/1000x1000x10.journal
tools/generatejournal 1000 10000 10 >examples/1000x10000x10.journal
tools/generatejournal 10000 1000 10 >examples/10000x1000x10.journal
tools/generatejournal 10000 10000 10 >examples/10000x10000x10.journal
tools/generatejournal 100000 1000 10 >examples/100000x1000x10.journal
tools/generatejournal 3 5 5 >examples/ascii.journal
tools/generatejournal 3 5 5 --chinese >examples/chinese.journal
tools/generatejournal 3 5 5 --mixed >examples/mixed.journal
```
## Docs
### Four kinds of documentation
20191209: needs update. See also doc/README.
<div style="margin:1em 2em; font-style:italic;">
"There is a secret that needs to be understood in order to write good
software documentation: there isn’t one thing called documentation,
there are four. They are: tutorials, how-to guides, explanation and
technical reference. They represent four different purposes or
functions, and require four different approaches to their creation."
--[Daniele Procida] (https://news.ycombinator.com/item?id=21289832)
</div>
https://github.com/simonmichael/hledger/tree/master/doc
Project documentation lives in a number of places:
- `site/*.md` is the hledger.org website content, which is generated with hakyll[-std] and pandoc
- haddock documentation in the code appears on Hackage
- short blurbs: cabal files, module headers, HCAR, GSOC project, ..
- `doc/notes.org` has some old developer notes
- developer reports (profiles, benchmarks, coverage..) in doc/profs, sometimes published at hledger.org/profs
## Funding
My vision for the hledger project has always been for it to be "accountable" and "self-sustaining", possibly through new forms of incentivisation.
Classic non-monetary FOSS communities are a beautiful and precious thing.
Adding money can change their dynamic.
Yet, we would enjoy having a lot more issues resolved, and a faster rate of progress.
So we experiment, gently.
Currently we use bounties as a way to encourage resolution of issues.
There are a few ways to do this:
1. You or your organisation can offer a bounty simply by saying so on the issue.
2. You can use Bountysource. A few hledger bounties have been completed there.
3. You can use the new Open Collective process below.
Issues with bounties of any kind are marked with the `bounty` label.
The Bounty Manager is @simonmichael.
### New bounty process
It currently looks like this, and will evolve:
- Issues are marked as bounties by @simonmichael. Feel free to suggest additional issues which should receive the bounty label.
- Bounties are paid from the hledger project's public Open Collective fund.
By contributing to the fund as an individual or organisation, you enable more bounties.
- These OC bounties (unlike 1 and 2 above) have standard amounts.
These may be adjusted over time, depending eg on the state of our funds.
Our current bounty amounts are
- level 1: 10 USD
- level 2: 25 USD
- level 3: 50 USD
- When you complete a bounty, submit an expense to Open Collective,
for whichever of the above bounty amounts you think appropriate,
based eg on time or expertise spent, how much you need it,
how much remains in our fund for other bounties, etc.
This will be reviewed by OC and (maybe ?) @simonmichael.
Successful claims, like donations, will appear in our public OC ledger.
Our bounty amounts are small, and nothing like professional rates in most countries,
but they still establish a principle of sustainability,
and help us to experiment.
You are encouraged to claim your bounties,
though you can also choose to transfer them to a new issue of your choice.
