用 Python 開(kāi)發(fā) Emoji 表情查找程序

今天分享一個(gè)前幾天構(gòu)建的小應(yīng)用程序,用來(lái)從命令行搜索emoji表情符號(hào)。
它可以通過(guò)OS命令行來(lái)完成,而且不必單擊任何東西即可獲得我的表情符號(hào),更加便捷。
該工具支持一次將多個(gè)匹配的表情符號(hào)復(fù)制到剪貼板。
- $ emo
- ------------------------------------------------------------------------------------
- Type one or more emoji related words ...
- End a word with a . if you want to select an emoji if there are multiple
- matches, otherwise the first match will be picked. Type 'q' to exit.
- > snake beer fire ninja
- Copying 🐍 🍺 🔥 🥷 to clipboard
- ------------------------------------------------------------------------------------
- Type one or more emoji related words ...
- End a word with a . if you want to select an emoji if there are multiple
- matches, otherwise the first match will be picked. Type 'q' to exit.
- > q
- Bye
至此,我的剪貼板上所有4個(gè)表情符號(hào)都寫(xiě)好了,在鍵盤(pán)輸入Cmd + V即可。
是不是很酷?
安裝并運(yùn)行程序包
- git clone git@github.com:PyBites-Open-Source/emojisearcher.git
- cd emojisearcher
- poetry install
- poetry run emo
poetry使依賴項(xiàng)管理變得輕而易舉,最后一個(gè)命令(別名)實(shí)際上有效,因?yàn)槲覍⑵浞旁趐yproject.toml文件中:
- [tool.poetry.scripts]
- emo = "emojisearcher.script:main"
您也可以通過(guò)添加以下shell別名來(lái)使調(diào)用命令更短(就像我在第一個(gè)示例中一樣):
- $ alias emo
- alias emo='cd YOUR_PATH/emojisearcher && poetry run emo'
(將YOUR_PATH更改為項(xiàng)目的路徑。)
文件夾結(jié)構(gòu)
由于有了poetry new,文件夾結(jié)構(gòu)從一開(kāi)始就遵循了公認(rèn)的最佳做法。
我喜歡將測(cè)試文件放在專用的tests /文件夾中。
庫(kù)
我使用emoji庫(kù)中的EMOJI_UNICODE常量來(lái)查找emoji表情:
- ...
- EMOJI_MAPPING = EMOJI_UNICODE[LANGUAGE]
- ...
- def get_emojis_for_word(
- word: str, emoji_mapping: dict[str, str] = EMOJI_MAPPING
- ) -> list[str]:
- return [emo for name, emo in emoji_mapping.items() if word in name]
然后我使用pyperclip復(fù)制到操作系統(tǒng)的剪貼板中:
- from pyperclip import copy
- ...
- def copy_emojis_to_clipboard(matches: list[str]) -> None:
- all_matching_emojis = ' '.join(matches)
- print(f"Copying {all_matching_emojis} to clipboard")
- copy(all_matching_emojis)
感謝這個(gè)庫(kù)的作者AlSweigart,這是一個(gè)很酷的程序包。
如何查找多個(gè)表情符號(hào)?
在這種情況下,我通過(guò)user_select_emoji函數(shù)進(jìn)入交互模式。
我想用一種創(chuàng)新的方式來(lái)觸發(fā)此交互模式,為此選擇了信號(hào)字符(SIGNAL_CHAR):如果用戶的搜索字符串以點(diǎn)(.)結(jié)尾,它將進(jìn)入交互模式。
原因如下:
- $ emo
- ------------------------------------------------------------------------------------
- Type one or more emoji related words ...
- End a word with a . if you want to select an emoji if there are multiple
- matches, otherwise the first match will be picked. Type 'q' to exit.
- > snake
- Copying 🐍 to clipboard
- ------------------------------------------------------------------------------------
- Type one or more emoji related words ...
- End a word with a . if you want to select an emoji if there are multiple
- matches, otherwise the first match will be picked. Type 'q' to exit.
- > flag
- Copying 🏴 to clipboard
- ------------------------------------------------------------------------------------
- Type one or more emoji related words ...
- End a word with a . if you want to select an emoji if there are multiple
- matches, otherwise the first match will be picked. Type 'q' to exit.
- > flag.
- 1 🏴
- 2 🏁
- 3 📪
- 4 📫
- 5 🎌
- 6 ⛳
- 7 📭
- 8 📬
- 9 🏴☠️
- 10 🏳️🌈
- 11 🏳️⚧️
- 12 🚩
- 13 🏳
- Select the number of the emoji you want: 12
- Copying 🚩 to clipboard
- ------------------------------------------------------------------------------------
- Type one or more emoji related words ...
- End a word with a . if you want to select an emoji if there are multiple
- matches, otherwise the first match will be picked. Type 'q' to exit.
- > q
- Bye
鍵入“snake(蛇)”后出現(xiàn)的emoji不會(huì)出錯(cuò),但是對(duì)于“flag(旗幟)”,它默認(rèn)選擇12個(gè)匹配項(xiàng)中的第一個(gè)(對(duì)于“heart(心臟)”,我們會(huì)得到130個(gè)匹配的表情符號(hào)!),這里我想手動(dòng)選擇一個(gè),因此鍵入點(diǎn)".",以做出進(jìn)一步的選擇。
測(cè)試
還有幾件事:
@ pytest.mark.parametrize非常好,可以使您的測(cè)試代碼更加簡(jiǎn)潔。
將代碼分解為更多的功能使其更可重用且更易于測(cè)試。
我測(cè)試了使用@patch(“ builtins.input”,side_effect = ['a',10,2,'q']的交互模式模擬input的方法。side_effect中的列表包含將“double” input的參數(shù)。這等效于以下內(nèi)容(在鍵入tree之后。):
- $ emo
- ------------------------------------------------------------------------------------
- Type one or more emoji related words ...
- End a word with a . if you want to select an emoji if there are multiple
- matches, otherwise the first match will be picked. Type 'q' to exit.
- > tree.
- 1 🎄
- 2 🌳
- 3 🌲
- 4 🌴
- 5 🎋
- Select the number of the emoji you want: a
- a is not an integer.
- 1 🎄
- 2 🌳
- 3 🌲
- 4 🌴
- 5 🎋
- Select the number of the emoji you want: 10
- 10 is not a valid option.
- 1 🎄
- 2 🌳
- 3 🌲
- 4 🌴
- 5 🎋
- Select the number of the emoji you want: 2
- Copying 🌳 to clipboard
- ------------------------------------------------------------------------------------
- Type one or more emoji related words ...
- End a word with a . if you want to select an emoji if there are multiple
- matches, otherwise the first match will be picked. Type 'q' to exit.
- > q
- Bye
測(cè)試代碼時(shí),一種有用的技術(shù)是刪除所有常見(jiàn)的前導(dǎo)空白。您可以為此使用textwrap.dedent,但是在這里我使用了替代的inspect.cleandoc。
上傳到PyPI
感謝toml文件中[tool.poetry]中的一些基本元數(shù)據(jù),發(fā)布到PyP非常簡(jiǎn)單:
- poetry build
- poetry publish
(首先使用--repository of publish在測(cè)試PyPI上嘗試一下,看是否一切正常。)
如果您喜歡這個(gè)項(xiàng)目,請(qǐng)?jiān)贕ithub上給它加星標(biāo),很高興能收到反饋。
