既存プロジェクトをPoetryで管理する方法

以前、以下の記事でMacでPoetryをインストールする方法を紹介しました。

7rikazhexde-techlog.hatenablog.com

今回はGitHubで管理する既存プロジェクトをPoetryで管理する方法を紹介します。

対象プロジェクトについて

以下リポジトリで管理するプロジェクトを対象として以下の2つの方法について確認しました。

  1. 既存のプロジェクトにpoetry環境を構築するpoetry initの例
  2. poetry newでひな形から新規作成する例

github.com

1. 既存のプロジェクトにpoetry環境を構築するpoetry initの例

これまで上記リポジトリでは以下のパッケージをrequirements.txtで管理していましたが、

  • PySimpleGUI
  • pandas
  • requests

Poetryを使用してプロジェクトの依存関係を管理するpyproject.tomlファイルを作成していきます。

既存のプロジェクトをgit cloneしてpoetry initを実行する

新規のプロジェクトを作るのではなく、既存のプロジェクトにpyproject.tomlファイルを作成するためにpoetry initコマンドを実行して初期化処理を実行します。

% git clone https://github.com/7rikazhexde/dlSubscanStakingRewardsHistory.git

dlSubscanStakingRewardsHistory % poetry init
Configuration file exists at $HOME/Library/Application Support/pypoetry, reusing this directory.

Consider moving configuration to $HOME/Library/Preferences/pypoetry, as support for the legacy directory will be removed in an upcoming release.

This command will guide you through creating your pyproject.toml config.

Package name [dlsubscanstakingrewardshistory]:  
Version [0.1.0]:  
Description []:  GUI application to save Reward&Slash data as csv file using PySimpleGUI and Subscan API
Author [[[user.name(git config)] <[user.email(git config)>, n to skip]:  
License []:  MIT
Compatible Python versions [^3.10]:  

main dependencies向けのパッケージ追加

次にプロジェクトで使用するパッケージを追加します。
main dependenciesで入力した情報は[tool.poetry.dependencies]の項目に追加されます。
パッケージを入力すると候補となるパッケージを検索してくれるので、[数字]の記載の番号を入力すると追加されます。

Would you like to define your main dependencies interactively? (yes/no) [yes] yes
You can specify a package in the following forms:
  - A single name (requests): this will search for matches on PyPI
  - A name and a constraint (requests@^2.23.0)
  - A git url (git+https://github.com/python-poetry/poetry.git)
  - A git url with a revision (git+https://github.com/python-poetry/poetry.git#develop)
  - A file path (../my-package/my-package.whl)
  - A directory (../my-package/)
  - A url (https://example.com/packages/my-package-0.1.0.tar.gz)

2. poetry newでひな形から新規作成する例

プロジェクトを新規作成する場合poetry new コマンドを実行します。

poetry newの指定

  • プロジェクト名: dlSubscanStakingRewardsHistory
  • パッケージ内のディレクトリ名: app --name オプションを指定することでproject以下のプロジェクトフォルダ名を指定できます。
% mkdir poetry_project
% cd poetry_project
poetry_project % poetry new dlSubscanStakingRewardsHistory --name app

Configuration file exists at $HOME/Library/Application Support/pypoetry, reusing this directory.

Consider moving configuration to $HOME/Library/Preferences/pypoetry, as support for the legacy directory will be removed in an upcoming release.

まとめ

実際のプロジェクトを使用してpoetry環境を構築する方法を紹介しました。 1. 既存のプロジェクトにpoetry環境を構築するpoetry initの例 2. poetry newでひな形から新規作成する例

コマンドはPoetry公式のBasic Usageに記載されています。
紹介した内容は基本的な部分であり、使用していないオプション指定やパッケージの更新などはドキュメントを参照しながら確認していきたいと思います。 また、今後はdevelopment dependenciesやpoetry.lockファイルを活用して、
機能追加やテストコードなどを考慮したプロジェクト管理ができるようにしていきたいと考えています。
