note

• vscode
  • settings
    • Please use monospaced Japanese fonts.
    • Please indent by space.
  • limitation
    • Multi-cursor is not supported.
  • internal implementation of double-byte characters
    • In vscode, many double-byte symbols are treated as half-width characters internally. As a result, moving the cursor up and down will cause it to rattle left and right. See isFullWidthCharacter() in https://github.com/microsoft/vscode/blob/main/src/vs/base/common/strings.ts
• boxdraw
  • spec
    • cursorUp/cursorDown
      • It suppresses left and right rattling when moving the cursor up and down due to the ruled line characters being calculated internally with one half-width character.
    • cursorDown
      • The bottom line does not implement the movement to move to the end of the line.
    • cursorUpSelect/cursorDownSelect
      • It does not implement control of the selection area.
