【PyCon2019】 Python製シェルXonshの紹介 $ M3, inc. $ Machine Learning Engineer $
Shunsuke Kawai ( @vaaaaanquish )
$ What’s Xonsh ? • Japanese:コンシュ • “Python” + “Shell
Script” on Shell • Made by Python ◦ Cross-platform ◦ Unix-gazing ◦ let’s start:pip install xonsh
$ Why Xonsh ? • Shell Scriptで複雑な処理を行いたくない! • Pythonが持つライブラリ等の資源、簡易な構文を活用できる Shell環境が欲しい!
fish xonsh POSIX-compatible Python Bourne Shell (sh)
$ Settable by Python • .xonshrc by Python and Shell
Script ◦ $PROMPT ◦ Key binding ◦ Completer … and more • Override built-in xonsh function by Python
$ Use Python property
$ Q&A Xonsh Q1 : 既存のshell scriptは読める? A : source_bashコマンドによって概ね使える
Q2 : 遅くない? A : Pythonの起動が遅いためxonshの起動は遅い。 動作はマシンスペック次第なので設定の勘所あり。 現在async/await対応中。 Q3 : Pythonがshellに最適な言語なの? A : 最適とは言っていない。 インタプリタ型言語とshell scriptを混合して資源を活用できているshellという立ち位置。 Q4 : 開発状況は? A : 2019/09/13時点で v0.9.11。いくつかのissueを超えて v1.0.0を予定。
