Fava-investor

This release brings fava_investor up to date with upstream changes in Fava. Primarily,
asset allocation by class was fixed. Thanks to contributors below.

Fixes

- Fix assetalloc_class chart (93) [Adriano Di Luzio]
- remove dead code for Fava <v1.18 (91) [Jakob Schnitzer]
- hierarchy chart: remove now uneeded modifier (90) [Jakob Schnitzer]
- libsummarizer crash in Fava (wrong pricemap) [Red S]
- build_beancount_pricemap() was missing in cli version. [Red S]

Improvements

- Fix to work with upstream changes (Fava 1.25+)

- Make currency regex not incorrectly match substrings (88) [Tyler Schicke]

This changes the currency regexes use '^<currency>$' instead of just
matching '<currency>', so that specifying a currency only matches that
currency exactly, instead of also matching currencies that contain the
specified currency.
- Preserve costs during tax adjustment (83) [korrat]

* Preserve costs during tax adjustment

Previously, tax adjustment discarded the cost of positions, causing
beancount.core.convert.convert_position to miss some conversion paths
via the cost currency. This necessitated a fallback to operating
currencies for finding viable transitive conversions.

With this patch, tax adjustment preserves the cost of positions.
Therefore, the cost currency is still available for automatic detection
of transitive conversions when computing the asset allocation.

One important assumption is that tax adjustment only ever encounters
costs after realization, as having a cost spec for the total cost would
change the cost per unit. This assumption is checked via assert and has
been manually tested without error on the multicurrency example.

The patch leaves the fallback logic for conversion via operating
currencies in place as an alternative when conversion via cost currency
fails.
* Fix lint warnings


- add --tax-burden to minimizegains. [Red S]
Interpolate tax burden from table for a specified amount
- add config table to gains minimizer. [Red S]
- minor: sort asset allocation output. [Red S]
- minor: clean up columns in gains minimizer. [Red S]
- minor: remove prefixes in asset allocation for clearer output. [Red S]
cli only
- minor: minimizegains: add avg and marginal tax percentage columns. [Red S]
- minor: cashdrag: add `min_threshold` option; convert to primary currency. [Red S]

Fixes

- summarizer fail due to favapricemap vs beancount pricemap. [Red S]
- cashdrag failed with command line (only worked with fava) [Red S]

- use beancount's convert_position, not fava
- asset_alloc_by_account to work with upstream changes. [Red S]

- fix cost_or_value from upstream changes
- broken tests. [Red S]
- breaks with new fava versions 86. [Red S]
- print warning when skipping negative positions in asset alloc. [Red S]
- minimizegains column deletion was incorrect. [Red S]

Other

Improvements

- asset allocation by class: fixed chart placement using upstream changes [Red S]

New

- minimizegains module. works on cli and fava. [Red S]

Improvements

- tlh/relatetickers: rename 'tlh_partners' to 'a__tlh_partners' [Red S]
In line with the other metadata fields, `tlh_partners` has been renamed
to `a__tlh_partners` and is now both an input and and auto-generated
field
- tlh/relatetickers: rename and add 'a__equivalents' [Red S]
In line with the other metadata fields, `equivalent` has been renamed to
`a__equivalents` and is now both an input and and auto-generated field
- tlh/relatetickers: remove tlh_partners_meta_label feature. [Red S]
this simplifies config, and clarifies.
- tlh: removed susubstantially_identical_meta_label feature. [Red S]
this is a simplification to provide clarity.
- tlh/relatetickers: Show only same type of TLH partners. [Red S]

Fixes

- 79 bump fava dependency to 1.22 due to upstream filtering changes. [Red S]
- minor: spelling. [Red S]
- beancountinvestorapi open method needed to index into list. [Red S]
- ticker_util: substidentical and a__substidentical are both accepted. [Red S]
- fix (summarizer, tlh, util): rename "similar" to "identical" [Red S]

IRS uses substantially identical
- libminimizegains: couldn't use arbitrary currencies. [Red S]

Other

- relatetickers: unit test. [Red S]
- pythonanywhere update.bash. [Red S]
- pythonanywhere example asset alloc looks nicer now. [Red S]
- pythonanywhere example is not too shabby now. 72 24. [Red S]
- ci: fix test. [Red S]
- refactor: add tlh substantially identical based wash sale example. [Red S]
- refactor: rename similars to idents. [Red S]
- ci: flake ignore. [Red S]
- doc/tlh: specifying substantially identical, and equivalent metadata. [Red S]
- refactor: remove 'substidenticals' meta label. [Red S]

use only a__substidenticals, which is both an input field, and gets
overwritten
- ci: flake. [Red S]
- ci: flake. [Red S]
- doc: feature todos for minimizegains. [Red S]
- doc: minimizegains README.txt. [Red S]
- wip: minimizegains. [Red S]

New

- new module: summarizer to summarize and display reasonably arbitrary tables of account
and commodity metadata
- Modules now respect GUI context (time interval). For example, see what your cashdrag
was or what you could have TLH'ed on any arbitrary day in the past
- experimental utility: scaled mutual fund NAV estimator: estimate a mutual fund's NAV
based on current intra-day value of its corresponding NAV

Improvements

- add footer to pretty_print. cashdrag uses it.
- assetalloc_class: read fava config from beancount file for command line.
- cashdrag: read fava config from beancount file for command line.
- cli: consolidated all modules into `investor` command.
- enable fava context and filters. Fixes 36. Also upstream favaledger.
- pager via click.
- ticker-util now puts asset allocation info it can find.
- tlh: comma betweeen similars and alts lists.
- tlh: read fava config from beancount file for command line.
- better example (still WIP)
- pythonanywhere config and example

Fixes

- fix: use filtered entries in query_shell.
- fix: 61 Show welcome message on initial screen when no modules are selected.
- fix/favainvestorapi: 67 get_account_open() returns empty.

Other

- several upgrades for fava 1.22 [Aaron Lindsay, Red S]
- several doc upgrades
- several refactors
- refactor: ticker-util cleanup; _ to - in options.

- wip: demo example 72.

New
- ticker-util. See [here](https://groups.google.com/g/beancount/c/eewOW4HQKOI)

Improvements
- tlh: allow specifying tlh_partner meta label. [Red S]
- tlh: also consider substantially similar tickers in wash sale computations. [Red S]
- tlh docs. [Red S]
- tlh new feature: wash_ids. [Red S]
