| 1 | +# Developing |
| 2 | + |
| 3 | +If you wish to develop for TagStudio, you'll need to create a development environment by installing the required dependencies. You have a number of options depending on your level of experience and familiarly with existing Python toolchains. |
| 4 | + |
| 5 | +<!-- prettier-ignore --> |
| 6 | +!!! tip "Contributing" |
| 7 | + If you wish to contribute to TagStudio's development, please read our [CONTRIBUTING.md](https://github.com/TagStudioDev/TagStudio/blob/main/CONTRIBUTING.md)! |
| 8 | + |
| 9 | +## Install Python |
| 10 | + |
| 11 | +Python [3.12](https://www.python.org/downloads) is required to develop for TagStudio. Any version matching "Python 3.12.x" should work, with "x" being any number. Alternatively you can use a tool such as [pyenv](https://github.com/pyenv/pyenv) to install this version of Python without affecting any existing Python installations on your system. Tools such as [uv](#installing-with-uv) can also install Python versions. |
| 12 | + |
| 13 | +<!-- prettier-ignore --> |
| 14 | +!!! info "Python Aliases" |
| 15 | + Depending on your system, Python may be called `python`, `py`, `python3`, or `py3`. These instructions use the alias `python` for consistency. |
| 16 | + |
| 17 | +If you already have Python installed on your system, you can check the version by running the following command: |
| 18 | + |
| 19 | +```sh |
| 20 | +python --version |
| 21 | +``` |
| 22 | + |
| 23 | +--- |
| 24 | + |
| 25 | +#### Installing with pyenv |
| 26 | + |
| 27 | +If you choose to install Python using pyenv, please refer to the following instructions: |
| 28 | + |
| 29 | +1. Follow pyenv's [install instructions](https://github.com/pyenv/pyenv/?tab=readme-ov-file#installation) for your system. |
| 30 | +2. Install the appropriate Python version with pyenv by running `pyenv install 3.12` (This will **not** mess with your existing Python installation). |
| 31 | +3. Navigate to the repository root folder in your terminal and run `pyenv local 3.12`. You could alternatively use `pyenv shell 3.12` or `pyenv global 3.12` instead to set the Python version for the current terminal session or the entire system respectively, however using `local` is recommended. |
| 32 | + |
| 33 | +--- |
| 34 | + |
| 35 | +### Installing Dependencies |
| 36 | + |
| 37 | +To install the required dependencies, you can use a dependency manager such as [uv](https://docs.astral.sh/uv) or [Poetry 2.0](https://python-poetry.org). Alternatively you can create a virtual environment and manually install the dependencies yourself. |
| 38 | + |
| 39 | +#### Installing with uv |
| 40 | + |
| 41 | +If using [uv](https://docs.astral.sh/uv), you can install the dependencies for TagStudio with the following command: |
| 42 | + |
| 43 | +```sh |
| 44 | +uv pip install -e .[dev] |
| 45 | +``` |
| 46 | + |
| 47 | +A reference `.envrc` is provided for use with [direnv](#direnv), see [`contrib/.envrc-uv`](https://github.com/TagStudioDev/TagStudio/blob/main/contrib/.envrc-uv). |
| 48 | + |
| 49 | +--- |
| 50 | + |
| 51 | +#### Installing with Poetry |
| 52 | + |
| 53 | +If using [Poetry](https://python-poetry.org), you can install the dependencies for TagStudio with the following command: |
| 54 | + |
| 55 | +```sh |
| 56 | +poetry install --with dev |
| 57 | +``` |
| 58 | + |
| 59 | +--- |
| 60 | + |
| 61 | +#### Manual Installation |
| 62 | + |
| 63 | +If you choose to manually set up a virtual environment and install dependencies instead of using a dependency manager, please refer to the following instructions: |
| 64 | + |
| 65 | +<!-- prettier-ignore --> |
| 66 | +!!! tip "Virtual Environments" |
| 67 | + Learn more about setting up a virtual environment with Python's [official tutorial](https://docs.python.org/3/tutorial/venv.html). |
| 68 | + |
| 69 | +1. In the root repository directory, create a python virtual environment: |
| 70 | + |
| 71 | + ```sh |
| 72 | + python -m venv .venv |
| 73 | + ``` |
| 74 | + |
| 75 | +2. Activate your environment: |
| 76 | + |
| 77 | + - Windows w/Powershell: `.venv\Scripts\Activate.ps1` |
| 78 | + - Windows w/Command Prompt: `.venv\Scripts\activate.bat` |
| 79 | + - Linux/macOS: `source .venv/bin/activate` |
| 80 | + |
| 81 | + <!-- prettier-ignore --> |
| 82 | + !!! info "Supported Shells" |
| 83 | + Depending on your system, the regular activation script _might_ not work on alternative shells. In this case, refer to the table below for supported shells: |
| 84 | + |
| 85 | + | Shell | Script | |
| 86 | + | ---------: | :------------------------ | |
| 87 | + | Bash/ZSH | `.venv/bin/activate` | |
| 88 | + | Fish | `.venv/bin/activate.fish` | |
| 89 | + | CSH/TCSH | `.venv/bin/activate.csh` | |
| 90 | + | PowerShell | `.venv/bin/activate.ps1` | |
| 91 | + |
| 92 | +3. Use the following PIP command to create an editable installation and install the required development dependencies: |
| 93 | + |
| 94 | + ```sh |
| 95 | + pip install -e .[dev] |
| 96 | + ``` |
| 97 | + |
| 98 | +## Nix(OS) |
| 99 | + |
| 100 | +If using [Nix](https://nixos.org/), there is a development environment already provided in the [flake](https://wiki.nixos.org/wiki/Flakes) that is accessible with the following command: |
| 101 | + |
| 102 | +```sh |
| 103 | +nix develop |
| 104 | +``` |
| 105 | + |
| 106 | +A reference `.envrc` is provided for use with [direnv](#direnv), see [`contrib/.envrc-nix`](https://github.com/TagStudioDev/TagStudio/blob/main/contrib/.envrc-nix). |
| 107 | + |
| 108 | +## Tooling |
| 109 | + |
| 110 | +### Editor Integration |
| 111 | + |
| 112 | +The entry point for TagStudio is `src/tagstudio/main.py`. You can target this file from your IDE to run or connect a debug session. The example(s) below show off example launch scripts for different IDEs. Here you can also take advantage of [launch arguments](./usage.md/#launch-arguments) to pass your own test [libraries](./library/index.md) to use while developing. You can find more editor configurations in [`contrib`](https://github.com/TagStudioDev/TagStudio/tree/main/contrib). |
| 113 | + |
| 114 | +<!-- prettier-ignore --> |
| 115 | +=== "VS Code" |
| 116 | + ```json title=".vscode/launch.json" |
| 117 | + { |
| 118 | + "version": "0.2.0", |
| 119 | + "configurations": [ |
| 120 | + { |
| 121 | + "name": "TagStudio", |
| 122 | + "type": "python", |
| 123 | + "request": "launch", |
| 124 | + "program": "${workspaceRoot}/src/tagstudio/main.py", |
| 125 | + "console": "integratedTerminal", |
| 126 | + "justMyCode": true, |
| 127 | + "args": ["-o", "~/Documents/Example"] |
| 128 | + } |
| 129 | + ] |
| 130 | + } |
| 131 | + ``` |
| 132 | + |
| 133 | +### pre-commit |
| 134 | + |
| 135 | +There is a [pre-commit](https://pre-commit.com/) configuration that will run through some checks before code is committed. Namely, mypy and the Ruff linter and formatter will check your code, catching those nits right away. |
| 136 | + |
| 137 | +Once you have pre-commit installed, just run: |
| 138 | + |
| 139 | +```sh |
| 140 | +pre-commit install |
| 141 | +``` |
| 142 | + |
| 143 | +From there, Git will automatically run through the hooks during commit actions! |
| 144 | + |
| 145 | +### direnv |
| 146 | + |
| 147 | +You can automatically enter this development shell, and keep your user shell, with a tool like [direnv](https://direnv.net/). Some reference `.envrc` files are provided in the repository at [`contrib`](https://github.com/TagStudioDev/TagStudio/tree/main/contrib). |
| 148 | + |
| 149 | +Two currently available are for [Nix](#nixos) and [uv](#installing-with-uv), to use one: |
| 150 | + |
| 151 | +```sh |
| 152 | +ln -s .envrc-$variant .envrc |
| 153 | +``` |
| 154 | + |
| 155 | +You will have to allow usage of it. |
| 156 | + |
| 157 | +<!-- prettier-ignore --> |
| 158 | +!!! warning "direnv Security Framework" |
| 159 | + These files are generally a good idea to check, as they execute commands on directory load. direnv has a security framework to only run `.envrc` files you have allowed, and does keep track on if it has changed. So, with that being said, the file may need to be allowed again if modifications are made. |
| 160 | + |
| 161 | +```sh |
| 162 | +cat .envrc # You are checking them, right? |
| 163 | +direnv allow |
| 164 | +``` |
| 165 | + |
| 166 | +## Building |
| 167 | + |
| 168 | +To build your own executables of TagStudio, first follow the steps in "[Installing Dependencies](#installing-dependencies)." Once that's complete, run the following PyInstaller command: |
| 169 | +
|
| 170 | +``` |
| 171 | +pyinstaller tagstudio.spec |
| 172 | +``` |
| 173 | +
|
| 174 | +If you're on Windows or Linux and wish to build a portable executable, then pass the following flag: |
| 175 | + |
| 176 | +``` |
| 177 | +pyinstaller tagstudio.spec -- --portable |
| 178 | +``` |
| 179 | + |
| 180 | +The resulting executable file(s) will be located in a new folder named "dist". |
