How do I enable automatic folding in Vim? set foldmethod=syntax doesn't seem to do much of anything. Eric Johnson To allow folds based on syntax add something like the following to your .vimrc : set foldmethod=syntax set foldlevelstart=1 let javaScript_fold=1 " JavaScript let perl_fold=1 " Perl let php_folding=1 " PHP let r_syntax_folding=1 " R let ruby_fold=1 " Ruby let sh_fold_enabled=1 " sh let vimsyn_folding='af' " Vim script let xml_syntax_folding=1 " XML Syntax based folding is defined in the language's syntax files which are located in $VIM/syntax. But some languages don't have folding

How to implement a list fold in Java

由 [亡魂溺海] 提交于 2019-11-27 12:11:58
问题 I have a List and want to reduce it to a single value (functional programming term "fold", Ruby term inject ), like Arrays.asList("a", "b", "c") ... fold ... "a,b,c" As I am infected with functional programming ideas (Scala), I am looking for an easier/shorter way to code it than sb = new StringBuilder for ... { append ... } sb.toString 回答1: What you are looking for is a string join() method which Java has since 8.0. Try one of the methods below. Static method String#join(delimiter, elements)

Is there any way to manually fold code in Eclipse?

问题 Is there any way to manually create fold points in code in Eclipse? I know how to enable folding and how to set the auto preferences, but i like being able to set my own fold points so I can ignore certain parts of my code. Think regions in VS. I know there is in VS and NetBeans, but I cannot find a way to set manual fold points in Eclipse. 回答1: I don't think Eclipse has built in manual folding, but I did use a previous version of the following plugin for it. Per the comment: The plugin has

Emacs equivalent of Vim's foldmethod = indent

由 核能气质少年 提交于 2019-11-27 06:49:56
问题 Question: Does Emacs have a canonical equivalent of Vim's Folding with Foldmethod=indent? I am particularly interested in something that can work alongside any Emacs major mode and any file. The Emacs searches have not turned up a definitive answer. 回答1: Seems like it can, though I don't use folding myself, so I've not tried it. Not surprisingly, the Python folks are all about this feature. See the following: http://mail.python.org/pipermail/tutor/2002-September/017482.html http://www.nabble

Scala: how to merge a collection of Maps

由 吃可爱长大的小学妹 提交于 2019-11-27 05:28:27
问题 I have a List of Map[String, Double], and I'd like to merge their contents into a single Map[String, Double]. How should I do this in an idiomatic way? I imagine that I should be able to do this with a fold. Something like: val newMap = Map[String, Double]() /: listOfMaps { (accumulator, m) => ... } Furthermore, I'd like to handle key collisions in a generic way. That is, if I add a key to the map that already exists, I should be able to specify a function that returns a Double (in this case)

问题 I noticed that fold texts can show useful information. They usually show something like +-- 5 lines: <div id="header-inner">-------------------------------------------- Is it possible to change the text in those lines? I noticed that something is possible in foldexpr but would it be possible to completely redesign folds? e.g. + <div id="header-inner"> : "possible comment from line above" : row 27 : length 5 thank you 回答1: There are a few things I don't understand from your question, such as

How can you implement regions a.k.a. code collapse for JavaScript in Visual Studio? If there are hundreds of lines in javascript, it'll be more understandable using code folding with regions as in vb/C#. #region My Code #endregion Blog entry here explains it and this MSDN question . You have to use Visual Studio 2003/2005/2008 Macros. Copy + Paste from Blog entry for fidelity sake: Open Macro Explorer Create a New Macro Name it OutlineRegions Click Edit macro and paste the following VB code: Option Strict Off Option Explicit Off Imports System Imports EnvDTE Imports EnvDTE80 Imports System

Java equivalent to #region in C#

由 为君一笑 提交于 2019-11-26 15:35:21
I want to use regions for code folding in Eclipse ; how can that be done in Java? An example usage in C# : #region name //code #endregion There's no such standard equivalent. Some IDEs - Intellij, for instance, or Eclipse - can fold depending on the code types involved (constructors, imports etc.), but there's nothing quite like #region . Jet Brains IDEA has this feature. You can use hotkey surround with for that (ctrl + alt + T). It's just IDEA feature. Regions there look like this: //region Description Some code //endregion Cyril Jacquart With Android Studio, try this: //region VARIABLES

What code folding plugins work on Eclipse 3.6?

由 自作多情 提交于 2019-11-26 13:10:20
I am new to java development environment and I find it difficult to manage my code properly. .Net provides the #regions which is a good solution for code management. I am using Eclipse environment for java development. I tried the Coffee-Bytes but the Coffee-Bytes code folding is not working in Eclipse 3.6 , at least on my side. I have configured it following this , but it does not work. Can someone guess what can be the issue? is there some other code folding plugin for Eclipse? The Nail For what it's worth, check my answer to this post to make it work in 3.7 (Indigo) getting an overview
