Use 4 spaces per indentation level. +* Code in a functional style, with concise functions that do one thing only. +* NEVER duplicate code. Always re-use existing code or create new helper functions. If they are reusable, add them to `utils.py` or `models.py` as appropriate. +* When importing, prefer explicit imports (`from sys import stderr`) rather than just importing the module. A critical example is doing `from os.path import join, dirname, abspath` instead of `import os` and then using `os.path.join()`, etc. Never mind how many imports this creates; explicit imports are preferred for clarity. +* Inside a package, prefer package-relative imports (`from .utils import helper_function`) rather than absolute imports (`from trmnl_server.utils import helper_function`). +* When creating new functions, include type hints for all parameters and return values. +* Do not create one-liner wrappers around existing/internal module functions unless absolutely necessary. Use the public ones instead. +* When considering creating utility functions, try not to create one or two-liners. Inline the logic instead if they are that simple. +* Add utility functions to `utils.py` and constants to `config.py`, making sure to import them where needed and that any major configuration parameters are handled in a consistent way. +* NEVER add import statements inside functions or methods. Add any and all imports at the top of the file. +* Only perform database operations in `models.py`. Create or re-use new helpers there as needed. +* Before writing new helpers or adding inline logic for things that might be reusable, check if there are existing ones that can be re-used or adapted in `utils.py` or `models.py`. + diff --git a/.github/workflows/pylint.yml b/.github/workflows/pylint.yml new file mode 100644 index 0000000..00bc32f --- /dev/null +++ b/.github/workflows/pylint.yml @@ -0,0 +1,33 @@ +name: Pylint + +on: [push] + +jobs: + build: + runs-on: ubuntu-latest + strategy: + matrix: + python-version: ["3.9", "3.10"] + steps: + - uses: actions/checkout@v4 + - name: Set up Python ${{ matrix.python-version }} + uses: actions/setup-python@v3 + with: + python-version: ${{ matrix.python-version }} + - name: Install dependencies + run: | + python -m pip install --upgrade pip + pip install pylint astroid + pip install -r requirements.txt + - name: Analysing the code with pylint + run: | + pylint_output=$(pylint $(git ls-files '*.py') --output-format=parseable | tee pylint.log) + echo "$pylint_output" + SCORE=$(echo "$pylint_output" | awk -F ' ' '/Your code has been rated at/ {print $7}' | cut -d'/' -f1) + if (( $(echo "$SCORE >= 9.0" | bc -l) )); then + echo "Pylint score ($SCORE) is acceptable." + exit 0 + else + echo "Pylint score ($SCORE) is too low." + exit 1 + fi diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..28d9750 --- /dev/null +++ b/.gitignore @@ -0,0 +1,15 @@ +.DS_Store +trmnl_log.json +db/clientData.txt +logs/server.log +ssl/cert.pem +config.yaml +ssl/key.pem +db/clientLog.txt +trmnl.db +venv/* +__pycache__/* +web/*.bmp +web/*.png +*.pyc +var/ diff --git a/.vscode/settings.json b/.vscode/settings.json new file mode 100644 index 0000000..9b38853 --- /dev/null +++ b/.vscode/settings.json @@ -0,0 +1,7 @@ +{ + "python.testing.pytestArgs": [ + "tests" + ], + "python.testing.unittestEnabled": false, + "python.testing.pytestEnabled": true +} \ No newline at end of file diff --git a/LICENSE b/LICENSE new file mode 100644 index 0000000..027c6c6 --- /dev/null +++ b/LICENSE @@ -0,0 +1,23 @@ +MIT License + +Based on previous work by the original project owner: https://github.com/ohAnd/trmnlServer + +Copyright (c) 2025 Rui Carmo + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in all +copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Plugins can be previewed via helper scripts under the repo root. +- **Color grading + dithering** – "color" grading and multiple dithering algorithms are available to improve image quality on e-ink panels. + +## Deployment + +I am deploying this with `kata`, a Docker-based service manager I wrote, but any method that can run a FastAPI app will work. + +## Running Locally + +```bash +git clone https://github.com/rcarmo/trmnlServer.git +cd trmnlServer +python3 -m venv .venv && source .venv/bin/activate +pip install -r requirements.txt +make serve +``` + +The server logs which port it binds to (default `SERVER_PORT=4567`). Point your TRMNL device at `http://:`. + +Useful commands: + +- `make serve` – start FastAPI using the current working directory as the runtime root. +- `SERVER_PORT=8081 make serve` – override port for quick tests. +- `make serve ARGS=/path/to/workdir` – run the server against a different working directory (`var/` contents plus SSL/generated assets) without touching your source tree. +- `python -m trmnl_server --list-plugins` – print the plugin registry (names + defaults) and exit. +- `python -m trmnl_server --run-plugin WeatherPlugin --plugin-output /tmp --plugin-arg image_root=/path` – run a single plugin once for debugging with optional keyword arguments. +- `make test` – run `pytest` (`tests/test_rotation.py`, `tests/test_plugins.py`, `tests/test_weather.py`). + +## Configuration + +All settings come from environment variables: + +- `SERVER_PORT`, `ENABLE_SSL` – networking defaults (4567/False out of the box, set `ENABLE_SSL=true` when you need TLS). +- `IMAGE_PATH`, `REFRESH_TIME`, `DITHERING_MODE` – rendering and dithering behaviour. +- `PHOTO_GRADING_ENABLED` – enable/disable photographic grading for image-heavy plugins (default: true). +- `EINK_TONE_POINTS`, `EINK_TONE_GAMMA` – optional grayscale response compensation points/gamma for panel-space quantization. +- `BATTERY_MAX_VOLTAGE`, `BATTERY_MIN_VOLTAGE`, `TIME_ZONE` – telemetry scaling. +- `SETUP_API_KEY`, `SETUP_FRIENDLY_ID`, `SETUP_MESSAGE` – `/api/setup` payload fields. +- `ASSETS_ROOT`, `STATIC_ROOT`, `GENERATED_ROOT` – relative directories (inside the working dir) for dashboard assets and generated BMP/PNG output (defaults: `web`, `web`, and `var/generated`). +- `CALIBRATION_PLUGIN_ENABLED` – set to `false` to remove calibration plugins from the registry and skip generating calibration assets. + +Whenever a setting is changed via the `/settings/*` endpoints, the new value is written to SQLite (table `config_entries`). On startup, `config.py` loads environment variables first (highest precedence) and then applies any persisted entries that are not overridden by the environment, so API-driven tweaks survive restarts without fighting `SERVER_PORT=...` overrides in your shell. + +Runtime artefacts now consolidate under `var/` inside your chosen working directory: + +- `var/db/trmnl.db` – SQLite database plus future state. +- `var/logs/` – reserved for future log sinks. +- `var/generated/` – plugin BMP/PNG output served via `/generated/*`. +- `var/ssl/` – self-signed certs generated automatically if SSL is enabled. + +FastAPI creates these directories during startup if they are missing, and `.gitignore` keeps `var/` out of version control. + +## Plugins & registry + +- Plugins are auto-discovered from `trmnl_server/plugins/` by the scheduler; any class inheriting `PluginBase` with `AUTO_REGISTER=True` is registered. +- Set `AUTO_REGISTER = False` on a plugin class to opt it out of the registry. +- Set `CALIBRATION_PLUGIN_ENABLED=false` (ENV or `/settings`) to remove all calibration plugins from the registry and skip generating calibration assets. +- `python -m trmnl_server --list-plugins` shows the active registry; `--run-plugin ` respects these toggles. + +## API + Static Surface + +| Path | Description | +| --------------------------------------------- |

"Formatting" units (e.g. formatting quarter) in the default en-US locale + * are the same as "stand-alone" units, but are different in some languages. + * "Formatting" units are declined according to the rules of the language + * in the context of a date. "Stand-alone" units are always nominative singular: + * + * `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'` + * + * `format(new Date(2017, 10, 6), 'do MMMM', {locale: cs}) //=> '6. listopadu'` + * + * 2. Any sequence of the identical letters is a pattern, unless it is escaped by + * the single quote characters (see below). + * If the sequence is longer than listed in table (e.g. `EEEEEEEEEEE`) + * the output will be the same as default pattern for this unit, usually + * the longest one (in case of ISO weekdays, `EEEE`). Default patterns for units + * are marked with "2" in the last column of the table. + * + * `format(new Date(2017, 10, 6), 'MMM') //=> 'Nov'` + * + * `format(new Date(2017, 10, 6), 'MMMM') //=> 'November'` + * + * `format(new Date(2017, 10, 6), 'MMMMM') //=> 'N'` + * + * `format(new Date(2017, 10, 6), 'MMMMMM') //=> 'November'` + * + * `format(new Date(2017, 10, 6), 'MMMMMMM') //=> 'November'` + * + * 3. Some patterns could be unlimited length (such as `yyyyyyyy`). + * The output will be padded with zeros to match the length of the pattern. + * + * `format(new Date(2017, 10, 6), 'yyyyyyyy') //=> '00002017'` + * + * 4. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales. + * These tokens represent the shortest form of the quarter. + * + * 5. The main difference between `y` and `u` patterns are B.C. years: + * + * | Year | `y` | `u` | + * |------|-----|-----| + * | AC 1 | 1 | 1 | + * | BC 1 | 1 | 0 | + * | BC 2 | 2 | -1 | + * + * Also `yy` always returns the last two digits of a year, + * while `uu` pads single digit years to 2 characters and returns other years unchanged: + * + * | Year | `yy` | `uu` | + * |------|------|------| + * | 1 | 01 | 01 | + * | 14 | 14 | 14 | + * | 376 | 76 | 376 | + * | 1453 | 53 | 1453 | + * + * The same difference is true for local and ISO week-numbering years (`Y` and `R`), + * except local week-numbering years are dependent on `options.weekStartsOn` + * and `options.firstWeekContainsDate` (compare [getISOWeekYear]{@link https://date-fns.org/docs/getISOWeekYear} + * and [getWeekYear]{@link https://date-fns.org/docs/getWeekYear}). + * + * 6. Specific non-location timezones are currently unavailable in `date-fns`, + * so right now these tokens fall back to GMT timezones. + * + * 7. These patterns are not in the Unicode Technical Standard #35: + * - `i`: ISO day of week + * - `I`: ISO week of year + * - `R`: ISO week-numbering year + * - `t`: seconds timestamp + * - `T`: milliseconds timestamp + * - `o`: ordinal number modifier + * - `P`: long localized date + * - `p`: long localized time + * + * 8. `YY` and `YYYY` tokens represent week-numbering years but they are often confused with years. + * You should enable `options.useAdditionalWeekYearTokens` to use them. See: https://git.io/fxCyr + * + * 9. `D` and `DD` tokens represent days of the year but they are ofthen confused with days of the month. + * You should enable `options.useAdditionalDayOfYearTokens` to use them. See: https://git.io/fxCyr + * + * ### v2.0.0 breaking changes: + * + * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes). + * + * - The second argument is now required for the sake of explicitness. + * + * ```javascript + * // Before v2.0.0 + * format(new Date(2016, 0, 1)) + * + * // v2.0.0 onward + * format(new Date(2016, 0, 1), "yyyy-MM-dd'T'HH:mm:ss.SSSxxx") + * ``` + * + * - New format string API for `format` function + * which is based on [Unicode Technical Standard #35](https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table). + * See [this post](https://blog.date-fns.org/post/unicode-tokens-in-date-fns-v2-sreatyki91jg) for more details. + * + * - Characters are now escaped using single quote symbols (`'`) instead of square brackets. + * + * @param {Date|Number} date - the original date + * @param {String} format - the string of tokens + * @param {Object} [options] - an object with options. + * @param {Locale} [options.locale=defaultLocale] - the locale object.

"Formatting" units (e.g. formatting quarter) in the default en-US locale + * are the same as "stand-alone" units, but are different in some languages. + * "Formatting" units are declined according to the rules of the language + * in the context of a date. "Stand-alone" units are always nominative singular. + * In `format` function, they will produce different result: + * + * `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'` + * + * `format(new Date(2017, 10, 6), 'do MMMM', {locale: cs}) //=> '6. listopadu'` + * + * `parse` will try to match both formatting and stand-alone units interchangably. + * + * 2. Any sequence of the identical letters is a pattern, unless it is escaped by + * the single quote characters (see below). + * If the sequence is longer than listed in table: + * - for numerical units (`yyyyyyyy`) `parse` will try to match a number + * as wide as the sequence + * - for text units (`MMMMMMMM`) `parse` will try to match the widest variation of the unit. + * These variations are marked with "2" in the last column of the table. + * + * 3. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales. + * These tokens represent the shortest form of the quarter. + * + * 4. The main difference between `y` and `u` patterns are B.C. years: + * + * | Year | `y` | `u` | + * |------|-----|-----| + * | AC 1 | 1 | 1 | + * | BC 1 | 1 | 0 | + * | BC 2 | 2 | -1 | + * + * Also `yy` will try to guess the century of two digit year by proximity with `referenceDate`: + * + * `parse('50', 'yy', new Date(2018, 0, 1)) //=> Sat Jan 01 2050 00:00:00` + * + * `parse('75', 'yy', new Date(2018, 0, 1)) //=> Wed Jan 01 1975 00:00:00` + * + * while `uu` will just assign the year as is: + * + * `parse('50', 'uu', new Date(2018, 0, 1)) //=> Sat Jan 01 0050 00:00:00` + * + * `parse('75', 'uu', new Date(2018, 0, 1)) //=> Tue Jan 01 0075 00:00:00` + * + * The same difference is true for local and ISO week-numbering years (`Y` and `R`), + * except local week-numbering years are dependent on `options.weekStartsOn` + * and `options.firstWeekContainsDate` (compare [setISOWeekYear]{@link https://date-fns.org/docs/setISOWeekYear} + * and [setWeekYear]{@link https://date-fns.org/docs/setWeekYear}). + * + * 5. These patterns are not in the Unicode Technical Standard #35: + * - `i`: ISO day of week + * - `I`: ISO week of year + * - `R`: ISO week-numbering year + * - `o`: ordinal number modifier + * - `P`: long localized date + * - `p`: long localized time + * + * 6. `YY` and `YYYY` tokens represent week-numbering years but they are often confused with years. + * You should enable `options.useAdditionalWeekYearTokens` to use them. See: https://git.io/fxCyr + * + * 7. `D` and `DD` tokens represent days of the year but they are ofthen confused with days of the month. + * You should enable `options.useAdditionalDayOfYearTokens` to use them.
