Emacs在工具提示中自动完成ESS而不是缓冲区 [英] Emacs auto-complete for ESS in tooltip instead of buffer

问题描述

我从以下资源中了解到：

• ，但建议不会实际产生相同的解决方案我的设置工具提示。但是对我来说这可能是一个平台问题呢？在Ubuntu 12.04上的海报也是如此 - 对于VitoshKa，Alex Vorobiev和Iqbal Ansari来说，解决方案可能在不同的平台上？您是否使用OS X？

  也许其他诊断：

    ac-source-R是在ess-rd.el中定义的变量。 
  它的值是（（前缀。ess-ac-start）
  （候选人ess-ac-candidates）
  （document. ess-ac-help））
   
   
  文档：
   R函数参数和R对象的组合广告完成源
   
   ac-source-R对象是在ess-rd.el中定义的变量。 
  它的值是（（前缀。ess-symbol-start）
  （候选人ess-ac-objects）
  （document。ess-ac-help-object））
   
   
  文档：
   R对象的自动完成源
   
   ac-source-R-args是在ess-rd.el中定义的变量。 
  它的值是（（前缀。ess-ac-start-args）
  （候选。ess-ac-args）
  （document. ess-ac-help-arg））
   
   
  文档：
   R函数参数的自动完成源
   
   [返回] 
    

  其中 ess-ac [TAB] 的变量只有...

   点击< mouse-2>完成选择它。 
  在此缓冲区中，键入RET以选择近点完成。 
   
  可能的完成是：
   ess-ac-R-argument-suffix 
   ess-ac-sources 
    

  所以也许问题是我的ESS安装缺少上面定义的所有 ess-ac - * 的东西，如 ess-ac-args 等？

  解决方案

  所以根据你的意见，在您的emacs配置中没有启用自动完成。所以只需启动自动完成，在你的init文件中添加这样的东西

   （加载auto-complete）
  （全局自动完成模式）
    

  对于ESS，您还需要将 ess-use-auto-complete 设置为 t 如下所示

   （setq ess-use-auto-complete t）
    

  编辑： ess-use-auto-complete 默认设置为 t 所以这一步不是真的需要。

  
  
  

  此外，由于您发现此选项令人困惑，我建议您打开一个问题在github回购中，以便维护者可以改进文档（或代码），无论哪个都可以减少混淆。

  
  
  

  自动完成有很多配置选项可以读取<一个href =http://cx4a.org/software/auto-complete/manual.html =nofollow>手册时间。

  
  
  

  很高兴我可以帮助

  
  

  I understand from the following resources:

  • http://www.emacswiki.org/emacs/ESSAuto-complete
  • http://www.emacswiki.org/emacs/AutoComplete
  • Emacs autocomplete-mode extension for ESS and R
  • Is it possible to get code completion for R in Emacs ESS similar to what is available in Rstudio?

  ...that I should have access to tooltips for auto-complete help in emacs when using ESS for R development. The last link additionally specifies that it should work out of the box with the latest ESS, and:

  From version 12.03 ESS integrates out of the box with auto-complete package.

  Three sources ‘ac-source-R-args’, ‘ac-source-R-objects’ and ‘ac-source-R’ are included in ESS distribution. The latest combines previous two and makes them play nicely together.

  I know that in general, my emacs tooltips are possible because they appear correctly with my python jedi setup in emacs.

  However, my emacs auto-complete does not work. Instead, there is a buffer at the bottom:

  instead of this, with the help superimposed on the working buffer:

  And I have the following in my init.el:

  (require 'auto-complete)
  (setq ess-use-auto-complete t)
  (ess-toggle-underscore nil)
  

  I have the following versions of:

    ess                20131207.1141  installed  No description available.
    ess-R-data-view    20130509.458   installed  Data viewer for GNU R
    ess-R-object-popup 20130302.336   installed  popup description of R object
    auto-complete      20140208.653   installed  Auto Completion for GNU Emacs
  

  What am I missing?

  UPDATE 1

  Here's my init for ESS stuff. This produces completions in a buffer, but not in a tooltip, where some configuration options from the manual have been added. (I have now tried all permutations of commenting and not commenting all of these):

  (require 'auto-complete)
  (global-auto-complete-mode)
  (require 'auto-complete-config)
  (ac-config-default)
  (require 'ess-site)
  (setq ess-use-auto-complete t)
  (setq ac-auto-start 2)
  (setq ac-auto-show-menu 0.2)
  (ess-toggle-underscore nil)
  

  UPDATE 2

  Similar question here, but the same solution is suggested which did not actually result in tooltips on my setup. But it suggests to me this might be a platform issue? The poster there was also on Ubuntu 12.04 as I am---is it possible the solutions that worked for VitoshKa, Alex Vorobiev, and Iqbal Ansari were on a different platform? Are you guys using OS X?

  UPDATE 3

  Maybe other diagnostics:

  ac-source-R is a variable defined in `ess-r-d.el'.
  Its value is ((prefix . ess-ac-start)
   (candidates . ess-ac-candidates)
   (document . ess-ac-help))
  
  
  Documentation:
  Combined ad-completion source for R function arguments and R objects
  
  ac-source-R-objects is a variable defined in `ess-r-d.el'.
  Its value is ((prefix . ess-symbol-start)
   (candidates . ess-ac-objects)
   (document . ess-ac-help-object))
  
  
  Documentation:
  Auto-completion source for R objects
  
  ac-source-R-args is a variable defined in `ess-r-d.el'.
  Its value is ((prefix . ess-ac-start-args)
   (candidates . ess-ac-args)
   (document . ess-ac-help-arg))
  
  
  Documentation:
  Auto-completion source for R function arguments
  
  [back]
  

  where the variables for ess-ac[TAB] are only...

  Click <mouse-2> on a completion to select it.
  In this buffer, type RET to select the completion near point.
  
  Possible completions are:
  ess-ac-R-argument-suffix
  ess-ac-sources
  

  So maybe the problem is my ESS install is lacking all ess-ac-* things defined above, like ess-ac-args, etc?

  解决方案

  So as per your comments it turned out that auto-complete was not enabled in your emacs config. So just enable auto-complete by adding something like this in you init file

  (load "auto-complete")
  (global-auto-complete-mode)
  

  Also for ESS you will need to set ess-use-auto-complete to t something like following would do

  (setq ess-use-auto-complete t)
  

  EDIT: ess-use-auto-complete is by default set to t so this step is not really needed.

  Also since you found this option confusing I would recommend you to open an issue on the github repo so that the maintainers can improve the documentation (or code) whichever can reduce the confusion.

  Auto-complete has a lot of configuration options do read the manual when you get time.

  Glad I could help
