[英]Emacs auto-complete for ESS in tooltip instead of buffer
I understand from the following resources: 我从以下资源中了解到:
...that I should have access to tooltips for auto-complete help in emacs when using ESS for R development. ...在使用ESS for R开发时,我应该可以访问工具提示以获取emacs中的自动完成帮助。 The last link additionally specifies that it should work out of the box with the latest ESS, and:
最后一个链接另外指定它应该与最新的ESS一起开箱即用,并且:
From version 12.03 ESS integrates out of the box with auto-complete package.
从版本12.03开始,ESS开箱即用,具有自动完整包。
Three sources 'ac-source-R-args', 'ac-source-R-objects' and 'ac-source-R' are included in ESS distribution.
ESS分布中包括三个来源'ac-source-R-args','ac-source-R-objects'和'ac-source-R'。 The latest combines previous two and makes them play nicely together.
最新的结合前两个,使他们很好地一起玩。
I know that in general, my emacs tooltips are possible because they appear correctly with my python jedi setup in emacs. 我知道,一般来说,我的emacs工具提示是可能的,因为它们在emacs中使用我的python jedi设置正确显示。
However, my emacs auto-complete does not work. 但是,我的emacs自动完成功能不起作用。 Instead, there is a buffer at the bottom:
相反,底部有一个缓冲区:
instead of this, with the help superimposed on the working buffer: 而不是这个,帮助叠加在工作缓冲区上:
And I have the following in my init.el: 我的init.el中有以下内容:
(require 'auto-complete)
(setq ess-use-auto-complete t)
(ess-toggle-underscore nil)
I have the following versions of: 我有以下版本:
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? 我错过了什么?
UPDATE 1 更新1
Here's my init for ESS stuff. 这是我对ESS的初始化。 This produces completions in a buffer, but not in a tooltip, where some configuration options from the manual have been added.
这会在缓冲区中生成完成,但不会在工具提示中生成,其中添加了手册中的某些配置选项。 (I have now tried all permutations of commenting and not commenting all of these):
(我现在尝试了评论的所有排列,而不是评论所有这些):
(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 更新2
Similar question here , but the same solution is suggested which did not actually result in tooltips on my setup. 类似的问题在这里 ,但建议相同的解决方案实际上没有导致我的设置工具提示。 But it suggests to me this might be a platform issue?
但它告诉我这可能是一个平台问题? 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?
那张海报也出现在Ubuntu 12.04上,因为我有可能为VitoshKa,Alex Vorobiev和Iqbal Ansari工作的解决方案在不同的平台上吗? Are you guys using OS X?
你们是否使用OS X?
UPDATE 3 更新3
Maybe other diagnostics: 也许其他诊断:
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... 其中
ess-ac[TAB]
的变量只是......
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? 所以也许问题是我的ESS安装缺少上面定义的所有
ess-ac-*
事物,比如ess-ac-args
等?
My auto-complete configuration also has 我的自动完成配置也有
(require 'auto-complete-config)
(ac-config-default)
and after that setting ess-use-auto-complete
makes ESS show the popup menus. 之后设置
ess-use-auto-complete
使ESS显示弹出菜单。
So as per your comments it turned out that auto-complete
was not enabled in your emacs config. 因此,根据您的意见,结果是您的emacs配置中未启用
auto-complete
功能。 So just enable auto-complete
by adding something like this in you init file 因此,只需在init文件中添加类似的内容即可启用
auto-complete
(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 同样对于ESS,你将需要设置
ess-use-auto-complete
对t
像下面会做
(setq ess-use-auto-complete t)
EDIT : ess-use-auto-complete
is by default set to t
so this step is not really needed. 编辑 :默认情况下,
ess-use-auto-complete
设置为t
因此不需要执行此步骤。
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. 此外,由于您发现此选项令人困惑,我建议您在github repo上打开一个问题,以便维护人员可以改进文档(或代码),以减少混淆。
Auto-complete has a lot of configuration options do read the manual when you get time. 自动完成有很多配置选项,当你有时间时,请阅读手册 。
Glad I could help 很高兴我能帮上忙
Don't confuse eldoc
with auto-completion. 不要将
eldoc
与自动完成混淆。 Eldoc is what you have in your screenshot, it shows all arguments of a function without being intrusive. Eldoc就是你的截图中的内容,它显示了函数的所有参数,而不是侵入性的。 Auto-completion pops up when you start typing stuff and activates after
ac-auto-start
characters. 当您开始输入内容时会弹出自动完成功能,并在
ac-auto-start
字符后激活。
