## How do I get started?

### Installation

`docker-finance` is not your typical Docker image in which you simply pull and containerize but rather, its an *image-based* accounting system that functions almost entirely within your container.

`docker-finance` *should* work out-of-the-box on any modern Linux system. For example, if your client (host) is Ubuntu, the default installation of `coreutils`, `shells` and `utils` that came with your system will satisfy requirements. However, you'll still need to manually install Docker (see below).

1. **Install dependencies** (most recent stable versions):
   - [Docker](https://docs.docker.com/engine/install/) with [post-install configuration](https://docs.docker.com/engine/install/linux-postinstall/)
   - GNU Bash 5.2+
     - If you don't have `bash` installed by default (or if `bash` is not your default shell), setup `bash` per your system's documentation
   - [Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git/), for step 3 (**strongly advised**):
     - `git` should be available via your package manager (e.g., `apt`, `pacman`, etc.).

2. **Open a `bash` shell**, if you haven't already done so.

3. **Copy/paste the following into your shell** (one-time repository clone and client preparation):
     ```bash
     bashrc=~/.bashrc
     aliases=~/.bash_aliases
     if [[ -f "$bashrc" && ! -f "$aliases" ]]; then
       if ! grep -E "(^\. ${aliases}|^source ${aliases})" "$bashrc" 1>/dev/null; then
         aliases="$bashrc"
       fi
     fi
     if git clone https://gitea.com/EvergreenCrypto/docker-finance; then
       if ! grep -E "^alias docker-finance=" "$aliases" 1>/dev/null; then
         echo "alias docker-finance='$(pwd)/docker-finance/client/docker.bash archlinux/$(whoami):latest'" >>"$aliases"
         source "$aliases"
       fi
     fi
     ```

4. **Verify your repository** (recommended):
     ```bash
     if pushd docker-finance/ 1>/dev/null; then
       gpg --keyserver hkp://keyserver.ubuntu.com --recv-key 518A22F85BEFD32BCC99C48603F90C4F35E0213E \
         && git verify-commit $(git log -n1 --pretty=format:"%H") \
         && echo -e "\nSUCCESS: now confirm matching key = 518A22F85BEFD32BCC99C48603F90C4F35E0213E" \
         || echo -e "\nFATAL: no key available or possible MITM - do not use!"
       popd 1>/dev/null
     fi
     ```

5. **Generate client/container environment** (see [Environment Generation](#environment-generation) for details):
     ```bash
     docker-finance gen
     ```

6. **Build the image and bring up container**:
     ```bash
     docker-finance build && docker-finance up
     ```

7. **You're inside!** See [How do I use it?](#how-do-i-use-it) for next steps.

### Environment Generation

`docker-finance`'s environment consists of two scopes: `client` and `container`. The client (host) view is confined to the host while the container view confined to the container (though the client *can*, at times, view from *within* the container's perspective). Think of the client as a class that inherits the container as a protected class with all the relevant permissions and scope.

In terms of configuration, the client (host) has two primary files, with one of them being mutually shared with the container. The 1st file is the [Client (Host) Configuration File](#client-host-configuration) and the 2nd file is a joint [Client/Container Superscript](#clientcontainer-superscript). Think of this **superscript** as the glue that binds the client/container scopes.

You'll create these files (and more) when running `docker-finance gen`, as seen below.

#### Client generation

> Client-side environment found, backup then generate new one?

Generates the client (host) configuration file. See the [Client (Host) Configuration File](#configuration-files) section for details.

 - You can use the generated defaults but make sure your directory layout matches accordingly
 - To easily edit this configuration file after `gen` is complete, run `docker-finance edit type=env`

#### Container generation

Container generation comes after (and *must* come after) client environment generation.

The container environment contains the bulk of configurations for everything you'll need while inside `docker-finance`.

---
> Generate (or update) container profile configs and/or accounts?

The container environment is a minimum requirement but here you'll have the option to continue generating or to backup a previous install.

---
> Will this profile be used for development and/or demonstration?

If you're a developer or wish to see the mockup test profile, select 'y' here.

> Enter profile name (e.g., family in 'family/alice')
> Enter subprofile name (e.g., alice in 'family/alice')

Container generation will always be for a specific `profile` with `subprofile`, and here is where you input that information.

For example, you could have a `family` profile with subprofiles of various family members or a `business` profile with subprofiles of all the various businesses you own.

It should be noted that:
  - all subsequent questions and container generation will relate to this `profile/subprofile` pairing
  - all output will be sent to the `${DOCKER_FINANCE_CONTAINER_FLOW}/profiles/profile/subprofile` path

---
> Generate (or update) joint client/container shell script (superscript)? [Y/n]

Select 'y' if this a first-run. If this is not a first-run but you need to regenerate the file, the select 'y'.

See [Superscript](#clientcontainer-superscript) for details.

---
> Generate (or update) container hledger-flow configs and/or accounts?

Not limited to `hledger-flow` data, this option leads to generating *all* `docker-finance` journal data (and configurations).

---
> Generate (or update) subprofile's shell script?

The container's subprofile's shell script is where all subprofile commands and aliases exist.

This file is generated on a per-subprofile basis and all custom code *on a per-subprofile basis* should go here.

---
> Generate (or update) subprofile's fetch configuration?

The container's fetch configuration is what all remote fetching relies on: prices, exchanges, blockchain explorers; all are configured here. See [Container Configurations](#container-configurations) for details.

---
> Generate (or update) subprofile's financial metadata?

The container's *per-subprofile* metadata file.

This file contains all your custom metadata and can edited with the `edit` and analyzed with the `meta` or `root` command. See [Container Configurations](#container-configurations) for details.

---
> Generate (or update) subprofile's hledger-flow accounts?

The container's `hledger-flow` accounts to be installed. These are the accounts described in [What is supported?](#what-is-supported).

**WARNING**: if you plan to use blockchain-based wallets (coinbase-wallet, pera-wallet, ledger, metamask, etc.), you **MUST** generate their respective chains, as seen during generation (`algorand`, `ethereum-based`, `tezos`, etc).

### Configuration Files

> Note: Docker volumes aren't used because of chicken-or-the-egg problem, regarding client configuration (among other reasons). `docker-finance` needs the client environment *before* building the Docker image and spawning the subsequent container (which would rely on volumes).

#### Client (host) configuration

The client (host) configuration file:
  - is located in the `${DOCKER_FINANCE_CLIENT_CONF}/client/env/` directory, with subdirectory format of `kernel-machine/platform/tag`
    - format consists of `username@hostname` where `username` is your host username and `hostname` is your machine's hostname
  - client/container configurations can be stored on shared NFS/CIFS or related network storage (with applicable user permissions)
    - allows for customizable locations of *all* container data on any mountable filesystem (as a replacement for Docker Volumes)
  - consists solely of variables in the format `DOCKER_FINANCE_VARIABLE=value` and is used by both Docker and `docker-finance`
  - default template variables can be found in [gen.bash](client/docker-finance.d/client/env/gen.bash), as described below

---
> DOCKER_FINANCE_CLIENT_CONF

Client (host) configuration path. Parent directory for client configuration files.


- Example: `DOCKER_FINANCE_CLIENT_CONF=/home/${USER}/.config/docker-finance.d`

---
> DOCKER_FINANCE_CLIENT_FLOW

Client (host) hledger-flow path. Parent directory for all profiles.

- Example: `DOCKER_FINANCE_CLIENT_FLOW=/net/nfs4/hledger-flow`

---
> DOCKER_FINANCE_CLIENT_REPO

Client (host) path for the `docker-finance` code repository (from the host's perspective).

This parent directory is where the `client` and `container` directories are located.

- Example: `DOCKER_FINANCE_CLIENT_REPO=/net/nfs4/git/docker-finance`

---
> DOCKER_FINANCE_CLIENT_SHARED

Client (host) path for the client/container shared directory.

The bind-mount is used exclusively for non-essential file sharing (custom scripts or any file you wish).

- Example: `DOCKER_FINANCE_CLIENT_SHARED=/mnt/share.d`

---

> DOCKER_FINANCE_CONTAINER_CMD

The container's `finance` command (useful for experimental implementations).

Default: `finance.bash` (internally aliased to `finance`)

- Example: `DOCKER_FINANCE_CONTAINER_CMD=finance.bash`

---
> DOCKER_FINANCE_CONTAINER_CONF

The container's configuration path (bind-mounted to client's (host's) configuration path).

- Example: `DOCKER_FINANCE_CONTAINER_CONF=/home/${USER}/.config/docker-finance.d`

---
> DOCKER_FINANCE_CONTAINER_EDITOR

The container's default text editor.

- Example: `DOCKER_FINANCE_CONTAINER_EDITOR=vim`

---
> DOCKER_FINANCE_CONTAINER_FLOW

The container's hledger-flow path from the container's perspective.

This path is bind-mounted to the client's (host's) hledger-flow path.

- Example: `DOCKER_FINANCE_CONTAINER_FLOW=/home/${USER}/hledger-flow`

---
> DOCKER_FINANCE_CONTAINER_REPO

The container's `docker-finance` code repository path (as viewed from the container).

This path is bind-mounted to the client's (host's) `docker-finance/container` path.

- Example: `DOCKER_FINANCE_CONTAINER_REPO=/home/${USER}/docker-finance`

---
> DOCKER_FINANCE_CONTAINER_SHARED

#### Client/Container Superscript

The client/container shell script (Superscript) is a bind-mounted (by directory) script that:
  - is the intermediary between client and container
  - is unique to each client (host) user (/home/alice, /home/bob, etc.)
  - is the glue that ties together **all** container [Subprofile](#subprofile) scripts
  - is generated on a per-client basis: all custom code on a **per-client basis** should go here

See the in-file comments for further documentation:

  - [superscript.bash.in](client/docker-finance.d/container/shell/superscript.bash.in)

> Note: as described in [Client (host) command format](#client-host-command-format), to edit this file, issue the client (host) command: `docker-finance edit type=shell`

#### Container Configurations

These configurations are confined solely to the container.

##### *Subprofile*

The Subprofile script is unique to each subprofile for each `profile/subprofile` within the `profiles` parent directory.

By default, this file will contain user aliases for all container commands. These aliases are mostly useful for small setups or setups with uniquely named subprofiles among all profiles.

See the in-file comments for further documentation:

  - [subprofile.bash.in](client/docker-finance.d/container/shell/subprofile.bash.in)

##### *Fetch*

The source of all remote API fetching configurations (exchanges, blockchains, market prices). This file is used by both the `fetch` and `edit type=fetch` commands.

See the in-file comments for further documentation:

  - [fetch.yaml.in](client/docker-finance.d/container/fetch/fetch.yaml.in)

##### *Meta*

The source of all custom metadata information (typically used to store cryptocurrency metadata information). This file is used by the `meta`, `edit type=meta` and `root` commands, as seen in [Meta (w/ ROOT C++ analysis)](#meta-w-root-c-analysis).

See the in-file comments for further documentation:

  - [meta.csv.in](client/docker-finance.d/container/meta/meta.csv.in)

## How do I use it?

### Mostly-Unified CLI

You'll only need to call two different scripts throughout your time using `docker-finance`:

  1. The client script which handles the client-side system: `docker.bash`
  2. The container script which handles the container-side system: `finance.bash`

These two scripts can be rationalized by the following format:

    <script> <super/sub> <command> [args]

> Note: for your convenience, command arguments [args] can be arranged in any order.

For example, these [Screenshots](#screenshots) describe a setup with mockup data where the client (host) user named `personal`, along with container `$DOCKER_FINANCE_USER` named `personal`, engage in client/container activity. The container profile named `testprofile` and its subprofile named `testuser` can be described as `<super/sub>` portion of the format (`testprofile/testuser`).

> Note: mockup data can be found in the `mockup` directories within this repository.

---

#### Client (Host) Command Format

The client (host) command format consists of:

    docker.bash <platform/username:tag> <command> [args]

Where:

  - `docker.bash` is located in `${DOCKER_FINANCE_CLIENT_REPO}/client`
  - `<platform/username:tag>`
    - `platform` is the image platform (archlinux, ubuntu)
    - `username` is the client (host) username with read/write permissions to the container (see [Configuration Files](#configuration-files))
    - `tag` is a custom tag you can use to delineate any number of images that you wish you create (`latest`, `dev`, etc.)
  - `<command>` is the command to pass to `docker.bash`
  - `[args]` are the (optional) arguments to pass to `<command>`

For a complete list of commands and usage help:

```bash
${DOCKER_FINANCE_CLIENT_REPO}/client/docker.bash archlinux/$(whoami):latest help
```

Or, if the [Installation](#installation) alias was properly created:

```bash
docker-finance help
```

You can also view the help usage of, for example, the `edit` command:

```bash
docker-finance edit help
```

---

#### Container Command Format

The container command format consists of:

    finance.bash <profile/subprofile> <command> [args]

Where:

  - `finance.bash` is located in `${DOCKER_FINANCE_CLIENT_REPO}/container`
  - `<profile/subprofile>`
    - `profile` is the profile, as defined during [Environment Generation](#environment-generation)
    - `subprofile` is the subprofile (user), as defined during [Environment Generation](#environment-generation)
  - `<command>` is the command to pass to `finance.bash`
  - `[args]` are the (optional) arguments to pass to `<command>`

> Note: by default, the finance command can be called by either `finance.bash` or `finance`.

For a complete list of commands and usage help:

```bash
finance help
```

You can also view the help usage of, for example, the `fetch` command (notice the need for `<profile/subprofile>`):

```bash
finance testprofile/testuser fetch help
```

> Note: the `finance` alias is named to avoid confusion with the client (host) command `docker-finance` - but you can still use the alias `docker-finance` *within* the container in place of all `finance` commands.

Or, use a subprofile alias, as described in [Subprofile](#subprofile):

```bash
testuser_fetch help
```

### Flow Layout

A primary read through of [hledger](https://hledger.org) and [hledger-flow](https://github.com/apauley/hledger-flow/blob/master/README.org) documentation should bring you up to speed on the essentials.

As for `docker-finance` specifics, create a test profile during [Environment Generation](#environment-generation) to see what your flow's layout should look like.
> Note: be sure to select 'y' when asked if this will be a development profile, and then go on to create account(s).

Once inside the container, assuming you created a profile named `testprofile` and subprofile named `testuser`, issue the following commands:

```bash
finance testprofile/testuser fetch all=price year=all && finance testprofile/testuser import year=2018
```
> Note: you **MUST** import from `2018` as there are mockup accounts that begin from that year

---

All profiles/subprofiles are installed into the parent directory `${DOCKER_FINANCE_CONTAINER_FLOW}/profiles`.

Peeking inside `${DOCKER_FINANCE_CONTAINER_FLOW}/profiles/profile/subprofile`, you'll see the following:

- `all-years.journal` and `directives.journal`
  - These top-level journals are generated by `hledger-flow`. Ignore these and use the `edit` command for journal editing.

- `docker-finance.d`
  - Location of all `docker-finance` configuration files (see `edit help` for details).

- `import`
  - Location of all CSV data and *real* journals. This is where you'll place CSV files and custom account/subaccount changes (see `edit help` for details).

- `prices`
  - Location of all market price data, by year, as acquired by `fetch price` (see `fetch help` for details).

- `reports`
  - Location of all generated reports, by year, as generated by `reports` (see `reports help` for details).

- `taxes`
  - Location of all generated taxes, by year, as generated by `taxes` (see `taxes help` for details).

---

Regarding any profile you create:

  - For manual CSV downloads, place you CSV file into your `${DOCKER_FINANCE_CONTAINER_FLOW}/profiles/profile/subprofile/import/subprofile/account/subaccount/1-in/year` directory - replacing `year` with the year of data that the file/data represents (see `import help` for details).
  - When you want to edit custom settings for an account or a subaccount, use the `edit` command (see `edit help` for details).
  - Your `hledger-flow` will contain a symlink called `src` which links to all the internal mechanics that process your data. **Do not delete this link**.

### Caveats & Oddities

#### Flow Layout

##### *Prices*

Before you try to infer market prices, be sure to fetch prices *before* you do your first import (or first import of the year). If you do not fetch, the prices journal will **not** be included within the import and, if you have a previous year of prices, **you will unwittingly infer against that previous year instead of your expected year!**

##### *Accounts: Trezor*

In the "Trezor Suite" app, change your wallet name to your subaccount(s). For example, to delineate between your Trezor One from several Trezor T devices, and to delineate between their separate wallets *within* every device, follow these steps:

Example, using your #2 Trezor T device and one of its BTC "storage" wallets:

   1. Change wallet name in app to `t-2:storage-1` as it's your Trezor T device #2, 1st bitcoin wallet named `storage-1` (versus your 2nd bitcoin wallet named `storage-2`, etc.)
   2. Export the CSV file to the appropriate directory. It will be in the format of `t_2_storage_1_20230629T230013.csv` (timestamp will be different)
   3. Rename the file to `t-2:storage-1_BTC.csv` (be sure to append the currency ticker to the file. So, `_BTC` if bitcoin or `_LTC` if litecoin, etc).

> Note: see Trezor `mockup` data within this repository, for a working example.

`docker-finance` relies on `Amount unit` within the file for the actual symbol/currency so, this file naming convention serves at least two purposes:

  1. This allows you to maintain device continuity by reusing wallet names for different currencies.
  2. This allows you to export, in the future, to the correct file from the associated hardware wallet because each hardware wallet exports its own unique CSV.

#### Taxes

- If you have a wallets designated for `SPEND`ing/`GIFT`ing or `INCOME`, you can use custom rules to mark all outgoing/incoming transactions as such (ex., using tags `taxed_as:SPEND`/`taxed_as:GIFT`/`taxed_as:INCOME`/etc.). See implementation for details.
- **WARNING**: *all* `GIFTIN` cost-basis must be manually entered from the corresponding `GIFT` results/calculations (as gifted from another).
  - For blockchain-related transactions, you can easily add cost-basis of a gift received (`GIFTIN`) by TXID in your custom rules
    - Example: despite Electrum providing `fiat_value`, you'll need to manually enter in your custom rules the correct `GIFT` value (if divergent)

### Development

You'll greatly benefit from building the [`dev-tools` image](#image-dev-tools), as seen in `docker-finance help`.

Additionally, when developing with the [`docker-finance` image](#image-docker-finance), please test your work with mockups as described in [Environment Generation](#environment-generation) and [Flow Layout](#flow-layout).
> Note: mockup CSVs will *intentionally* have multiple years within in a `1-in/year` directory in order to test for year parsing.

#### Pull Request

The following assumes that the command `docker-finance_dev-tools` has been properly aliased, per `docker-finance help`.

Before sending a pull request:

1. If you created a new file, please run `docker-finance_dev-tools license file=/path/to/new/file.ext` and update the copyright date and author.
2. For any work that utilizes Bash/C++/PHP, please run the linter for your respective language (e.g., `docker-finance_dev-tools linter type=bash`).
   - See `docker-finance_dev-tools linter help` for details.
3. As for style guidelines, these are recommended:
   - [Bash](https://google.github.io/styleguide/shellguide.html)
   - [C++](https://google.github.io/styleguide/cppguide.html)
   - [PHP](https://github.com/PHP-CS-Fixer/PHP-CS-Fixer/blob/master/doc/ruleSets/PhpCsFixer.rst)
4. If you can, please document the code in Doxygen style where applicable and run `docker-finance_dev-tools doxygen gen` to see your code documentation.

#### Notes

- As described in [Mostly-Unified CLI](#mostly-unified-cli), to use a developer version of the `finance` image (not a `dev-tools` image), simply build and tag a new `finance` image with `dev` (or whatever you see fit), and reset the `docker-finance` alias at your discretion.
- Run `DOCKER_FINANCE_DEBUG=true docker-finance <cmd> [args]` to debug *before* the [Client (Host) Configuration File](#client-host-configuration) file is read.
- The `.C` files you see in the repository are ROOT.cern macro files, not C-language files.
