今天分享一个前几天构建的小应用程序,用来从命令行搜索emoji表情符号。
它可以通过OS命令行来完成,而且不必单击任何东西即可获得我的表情符号,更加便捷。
该工具支持一次将多个匹配的表情符号复制到剪贴板。
- $ 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,我的剪贴板上所有4个表情符号都写好了,在键盘输入Cmd + V即可。
是不是很酷?
安装并运行程序包
- git clone git@github.com:PyBites-Open-Source/emojisearcher.git
- cd emojisearcher
- poetry install
- poetry run emo
poetry使依赖项管理变得轻而易举,最后一个命令(别名)实际上有效,因为我将其放在pyproject.toml文件中:
- [tool.poetry.scripts]
- emo = "emojisearcher.script:main"
您也可以通过添加以下shell别名来使调用命令更短(就像我在第一个示例中一样):
- $ alias emo
- alias emo='cd YOUR_PATH/emojisearcher && poetry run emo'
(将YOUR_PATH更改为项目的路径。)
文件夹结构
由于有了poetry new,文件夹结构从一开始就遵循了公认的最佳做法。
我喜欢将测试文件放在专用的tests /文件夹中。
库
我使用emoji库中的EMOJI_UNICODE常量来查找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复制到操作系统的剪贴板中:
- 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)
感谢这个库的作者AlSweigart,这是一个很酷的程序包。
如何查找多个表情符号?
在这种情况下,我通过user_select_emoji函数进入交互模式。
我想用一种创新的方式来触发此交互模式,为此选择了信号字符(SIGNAL_CHAR):如果用户的搜索字符串以点(.)结尾,它将进入交互模式。
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
键入“snake(蛇)”后出现的emoji不会出错,但是对于“flag(旗帜)”,它默认选择12个匹配项中的第一个(对于“heart(心脏)”,我们会得到130个匹配的表情符号!),这里我想手动选择一个,因此键入点".",以做出进一步的选择。
测试
还有几件事:
@ pytest.mark.parametrize非常好,可以使您的测试代码更加简洁。
将代码分解为更多的功能使其更可重用且更易于测试。
我测试了使用@patch(“ builtins.input”,side_effect = ['a',10,2,'q']的交互模式模拟input的方法。side_effect中的列表包含将“double” input的参数。这等效于以下内容(在键入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
测试代码时,一种有用的技术是删除所有常见的前导空白。您可以为此使用textwrap.dedent,但是在这里我使用了替代的inspect.cleandoc。
上传到PyPI
感谢toml文件中[tool.poetry]中的一些基本元数据,发布到PyP非常简单:
- poetry build
- poetry publish
(首先使用--repository of publish在测试PyPI上尝试一下,看是否一切正常。)
