code-snippets

Sometimes I still get stuck trying to translate procedural code into functional code. Is there a list of functional idioms/snippets that are mapped to procedural idioms/snippets? Edit Since there doesn't seem to be a centralized website of these snippets, I am turning this into a community wiki. Please paste any procedural -> functional snippets here. (Edited from this post on fshub ) The first time I went to reach for break/continue in OCaml/F#, it threw me for an (infinite) loop, so to speak, because no such thing exists! In OCaml, one can use exceptions to break from a loop because they are

While trying to write my own snippets for Sublime Text 2, I ran into the following two problems: Finding scope keys . I figured out that I can look through my packages one by one and find references to a declared "scope" property. For example in ~/Library/Application Support/Sublime Text 2/Packages/JavaScript/Comments.tmPreferences (a file in my HTML package) there's these two lines: <key>scope</key> <string>source.js</string> So if I want my current snippet to work on javascript files, I define my scope like: <scope>source.js</scope> I'm assuming all these scope keys are defined on-the-fly

Is there any way that we can create snippets in Atom with variables (someway like Emmet did in HTML)? Here's an example that we want to achieve: From: p4 To: padding: 4% 4% 4% 4% ( From: p[i] to padding: i% i% i% i% ) (the user input p+[i] , i is variable ) To my knowledge you are not able to do that with Atom snippets because they are composed with just CSON (i.e. no scripting). So while you can't do that you can use a single variable and expand it into multiple locations in your snippet, something I learned in this blog that I read here Taken from that post, here is example CSON to do that:

I'm frustrated with the default behavior of autocomplete overriding key bindings used by yasnippets . Is there a way to set a precedence so that tab will try to expand a snippet before trying to autocomplete the word? Quick disclosure: I'm using evil-mode. If they're both minor modes, then precedence is determined by the order of elements in minor-mode-map-alist which, unless explicitly manipulated, is simply determined by the order in which the libraries were loaded. Ensure that autocomplete is loaded before yasnippet , and yasnippet's minor mode map would have precedence. You could also use

#include<stdio.h> int main() { int a=32; printf("%d\n", ~a); //line 2 return 0; } o/p = -33 Actually in the original snippet line 2 was printf("%x\n", ~a); //line 2 I solved it like 32 in hex is 20. 0000 0000 0010 0000 now tilde operator complements it 1111 1111 1101 1111 = ffdf. I am confused how to solve it when I have printf("%d\n", ~a); //line 2 i.e %d NOT %x. In your C implementation, as in most modern implementations of any programming language, signed integers are represented with two’s complement . In two’s complement, the high bit indicates a negative number, and the values are

Yasnippet snippets that has a percent sign, % , ending a line with the last point of the snippet, $0 , before the percent sign acts strange in that the cursor gets placed after the percent sign and not before it. I wonder how I can avoid this strange behavior. Consider the following snippet: # -*- mode: snippet -*- # name: test snippet # key: ts # -- { $0% } I take it that as it's activated it should insert three lines where the first contains { , the last line } and the second line % and place the cursor before % on the second line as in the following example: { [cursor]% } But what happens

So when I create a class for example in visual studio code, I can do it all manual and then code completion works just fine see image below: So in the image above I have typed all the code so far by hand NOT using any snippets. But in the image below I created the class using a snipped see image below: But When I fill in the required fields from the snippet code completion is not working. See image below: So my question really is how do I get code completion / suggestions to work inside of the fields of a snippet? Or is this not possible in vscode? If any clarification or extra information is

I'm utilizing a Macbook pro running "El Capitan" and RStudio is version 0.99.902. I'm writing a Rmd document. I want to utilize the snippets that RStudio has built in and create my own also. By clicking Preference => Code; I can see that "Enable code snippets" is checked. However, while trying to utilize any snippet the completion is not performed. If I typed just r I should get this block of code, but nothing hapen snippet r ```{r ${1:label}, ${2:options}} ${0} ``` I also create a simple snippet: snippet dthen %>% None of the markdown snippet seems to work. Do I'm doing something wrong or any
