问题描述

在用于Atom的Python3中使用f字符串时，它不会正确地自动完成字符串。键入

types_of_people = 10
x = f"There are {types_of_people} types_of_people."

我开始键入时收到x = f"...，但末尾引号不自动补全

当我键入结束引号时，我得到x = f"There are {types_of_people} types_of_people."""

如何根据需要使结尾引号自动完成？

我转到了这个链接。但当我输入结束引号时，Atom仍会打印额外的引号，而不是只给出结束引号。

推荐答案

方法1

编辑文件时，键入snip，然后按Tab。它应该生成如下示例配置：

'.source.js':
  'Snippet Name':
    'prefix': 'Snippet Trigger'
    'body': 'Hello World!'

将以上内容编辑为：

'.source.python':
  'f-string':
    'prefix': 'f"'
    'body': 'f"$1"'

此方法中的f-string的自动完成仅在键入f"后按TAB时触发

方法2

将以下行添加到ATOM编辑器的相应配置文件中：

1. init.coffee

atom.commands.add 'atom-text-editor', 'custom:insert-double-quotes', ->
  # Get the active text editor instance
  editor = atom.workspace.getActiveTextEditor()
  # Get the character under the current position of the cursor
  currentCharacterPrefix = editor.getLastCursor().getCurrentWordPrefix().slice(-1) 

  # Check if the character prefix is 'f'
  if(currentCharacterPrefix == 'f') 
    # Insert double quotes with cursor position set in between the double quotes
    snippetBody = '"$1"' 
    atom.packages.activePackages.snippets?.mainModule?.insert snippetBody
  else
    # If prefix is not 'f', then insert a double quote 
    # as if entering it manually in the text editor 
    # (so bracket-matcher does it's autocomplete job)
    editor.insertText(""") 

2. keymap.cson

# Set a key binding for double quote to trigger the command in the init script
'atom-text-editor[data-grammar="source python"]':
  '"': 'custom:insert-double-quotes'

此方法的灵感来自于此答案here。

在方法2中，还有另一种方法可以使括号匹配器程序包认为它只是添加正常的括号对。(不需要禁用括号匹配器中""的自动完成)

将以下行添加到init.coffee配置文件：

atom.commands.add 'atom-text-editor', 'custom:insert-double-quotes', ->
  # Get the active text editor instance
  editor = atom.workspace.getActiveTextEditor()
  # Get the character under the current position of the cursor
  currentCharacterPrefix = editor.getLastCursor().getCurrentWordPrefix().slice(-1) 

  # Check if the character prefix is 'f'
  if(currentCharacterPrefix == 'f') 
    # Fool the Bracket Matcher package by inserting a space
    editor.insertText(" ")
    # Insert a double quote for bracket matcher to handle auto-complete job
    editor.insertText(""")
    # Set cursor position to remove the space
    editor.getLastCursor().moveLeft(1)
    editor.backspace()
    # Set cursor position in between the double quotes 
    editor.getLastCursor().moveRight(1)
  else
    # If prefix is not 'f', then insert a double quote 
    # as if entering it manually in the text editor 
    # (so bracket-matcher does it's autocomplete job)
    editor.insertText(""")
