Scite 强制等宽字体

wiki

稍加修改，就有可能自动让某些文件类型以等宽字体打开。这样就可以在等宽字体和比例字体混合的环境中工作，而无需一直按 Ctrl+F11。

该脚本通过覆盖常规样式属性来强制缓冲区进入等宽模式。它使用 extman 来挂钩 OnSwitchFile。

      editor.StyleFont[i] = MonoFont
      editor.StyleSize[i] = MonoSize
    end
    editor:Colourise(0, -1)
  end
  scite_OnSwitchFile(function() if buffer[SIG] then AllMono() return true end end)
  buffer[SIG] = true
  AllMono()
end

  -- retrieve monospace font information
  local StyleMono = {}
  local monoprop = props["font.monospace"]
  for style, value in string.gfind(monoprop, "([^,:]+):([^,]+)") do
    StyleMono[style] = value
  end
  -- grab styles, assuming they are defined
  MonoFont = StyleMono.font
  MonoSize = tonumber(StyleMono.size)

function ToggleMonospace()
    scite.MenuCommand(450)
    return false
end

scite_OnOpen(ToggleMonospace)

要确保新创建的文件以等宽模式启动，可以尝试

function ToggleMonospace()
  -- the buffer table is provided for user data
  if buffer and not buffer["MadeMonospace"] then
    scite.MenuCommand(IDM_MONOFONT)
    buffer["MadeMonospace"] = true
  end
end

function OpenMonospace(filename) 
  if filename ~= "" then 
    ToggleMonospace()
  end
end

-- OnOpen event (with empty filename) is generated when SciTE starts
--  with new file, but not when File->New creates another new file tab.
scite_OnOpen(OpenMonospace)  -- for opening existing file
scite_OnSavePointLeft(ToggleMonospace) -- first character typed in new file
