image - How to implement a free version of WebImageSearch?


I really don't like functions that I have to pay for, if they can be implemented for free.


Is there a way to get around this pay-wall for WebImageSearch? Perhaps using some other free api or service?


enter image description here


Update:


One idea I had was to use the french search engine Qwant which has an api which is free and unlimited for now: https://api.qwant.com/api/search/images?count=10&offset=1&q=cars (but has less accuracy than Google or Bing).


enter image description here



Answer



So after being wrong about Bing being free, we'll pursue my other suggestion, which was to use the ServiceConnect framework. I demonstrate how to use it in general here.


For the purposes of this, though, here's what all you need to do. Get the paclet by running this:



(* 
  If you've already installed, replace this with PacletUpdate 
  to get the newest version
  *)
PacletInstall[
 "ServiceConnection_Qwant",
 "Site" -> 
  "https://www.wolframcloud.com/objects/b3m2a1.paclets/PacletServer"
 ]


Service connect like so:


$so = ServiceConnect["Qwant"]

qwant


And run it like so:


$so["ImageSearch", "q" -> "car", "count" -> "3"]

result example


I also provide access to the basic web search endpoint:


$so["WebSearch", "q" -> "pizza"]


web search results



Inspecting the ServiceObject


In all my service connections I include a way to access what parameters I've fed in. The request that implements this is called "RequestParameters", named similarly to the "Requests" request that all ServiceObjects have by default. You use it like so:


$so["RequestParameters", "Request" -> "WebSearch"]

<|"Parameters" -> {"q", "count", "offset", "page"}, "Required" -> {}|>

(Note before v1.0.2 of this paclet this will return an empty list, as "WebSearch" really delegates to the standard "Search" method. Use PacletUpdate to get the newest version if you don't have it.)

functions - Get leading series expansion term?

Given a function f[x] , I would like to have a function leadingSeries that returns just the leading term in the series around x=0 . For example: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x)] x and leadingSeries[(1/x + 2 + (1 - 1/x^3)/4)/(4 + x)] -(1/(16 x^3)) Is there such a function in Mathematica? Or maybe one can implement it efficiently? EDIT I finally went with the following implementation, based on Carl Woll 's answer: lds[ex_,x_]:=( (ex/.x->(x+O[x]^2))/.SeriesData[U_,Z_,L_List,Mi_,Ma_,De_]:>SeriesData[U,Z,{L[[1]]},Mi,Mi+1,De]//Quiet//Normal) The advantage is, that this one also properly works with functions whose leading term is a constant: lds[Exp[x],x] 1 Answer Update 1 Updated to eliminate SeriesData and to not return additional terms Perhaps you could use: leadingSeries[expr_, x_] := Normal[expr /. x->(x+O[x]^2) /. a_List :> Take[a, 1]] Then for your examples: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x), x] leadingSeries[Exp[x], x] leadingSeries[(1/x + 2 + (1 - 1/x...

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...
