canopy fsx only version

[amirrajan]

Just wanted to leave a marker open with regards to a version of canopy that can be run without Visual Studio. Here is what I have so far: https://github.com/amirrajan/canopy-fsx

If you have fsi in your PATH, you should be able to clone this repo, and just runfsi program.fsx.

If you want, we can put a link to it on the main gh page?

[amirrajan]

I don't think it's ready for prime time yet. Want to get an "it just works" installation for Mono/Windows up and running. Basically someone without Visual Studio should be able to clone this repo (or download the zip) and run install.bat or install.sh. Install F# runtime and supporting updates to the PATH.

Could the .dll of Canopy be loaded as a dll and not fsx's?
so that in theory you could do something like.

#r canopy.dll

open canopy
start firefox

"taking canopy for a spin" &&& fun _ ->
    url "http://lefthandedgoat.github.io/canopy/testpages/"
    "#welcome" == "Welcome"
    "#firstName" == "John"

run()

or even have it so I could have a runner where I could say

canopy run test.fsx

[amirrajan]

You can use nuget.exe and install the lastest canopy. I figured that I'd just make the entire source available if you're going all FSX. The directory would be placed in the room folder and you can use the #r option like so: https://github.com/amirrajan/canopy-fsx/blob/master/canopy/runner.fsx#L6

I have a solution with .fs files and it can be run from Visual Studio , what should i do to run from command line without changing all files into fsx.

[lefthandedgoat]

If its a console app just build and run the exe. If you want to run from
REPL it will be more work

I've adapted a script from fsharpforfunandprofit.com as below. You need to call as fsi --noframework Script.fsx. Here is the script file which calls your DLL and tuns it:

(* ======================================================
Use F# to run unit tests without having to install NUnit
From command line run:
  fsi --noframework Script.fsx 

In my system, fsi.exe is located here:
  C:\Program Files (x86)\Microsoft SDKs\F#\4.0\Framework\v4.0\Fsi.exe

Adapted from the article "Low risk ways to use F# at work"
  http://fsharpforfunandprofit.com/posts/low-risk-ways-to-use-fsharp-at-work/

//    nuget install NUnit.Runners -o Packages -ExcludeVersion

Thank you for the reply. Yes i did execute the exe but I am trying to do it through a script fsx file. My tests are in tests.fs and im running run() them from Program.fs . Now , I want to create a script and run it with F# interactive. Do you have any example code in this kind of scenario.

[danuma]

Thank you . I will try this.

[galatrash]

AFAIK, .fs files can't be run interactively; they need to be compiled in an exe or dll to be executed.

[vbop9834]

.fs files can be executed interactively in a .fsx file by loading the .fs file as a dependency in the script

Place the script script.fsx in the same folder as Program.fs

#I __SOURCE_DIRECTORY__
#load "Program.fs"

//Load canopy here as well
#I "path_to_directory_containing_canopy_dll"
#I "path_to_directory_containing_webdriver_dll"
#r "canopy.dll"
#r "WebDriver.dll"

open canopy
open YourNamespace.ProgramModule

run ()

I'm trying to run this: https://github.com/amirrajan/canopy-demo/blob/master/LightingTalk/Sandbox.fsx from the same project. It used to work fine, but it looks like a chrome or chromedriver update broke it. Now I get:

OpenQA.Selenium.WebDriverException: A exception with a null response was thrown sending an HTTP request to the remote WebDriver server for URL http://localhost:58450/session/5c27d8a2d45c51d7853215774bdb82c7/window/current/size. The status of the exception was ReceiveFailure, and the message was: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

Looks like its using an older version of Selenium. Update that to the latest, with latest chrome and chrome driver and it should work.

[navmed]

I've updated Selenium.Webdriver and Selenium,Support to 3.0.0, ChromeDriver updated to 2.2.7, Canopy to 1.0.6. This is my current fsx file and I've double-checked to make sure the references are pointing to the right versions.

#I @"C:\Projects\CanopyFalcon\packages\Selenium.WebDriver.3.0.0\lib\net40\"
#I @"C:\Projects\CanopyFalcon\packages\Selenium.Support.3.0.0\lib\net40\"
#I @"C:\CanopyPackages\SizSelCsZzz.0.3.36.0\lib\"
#I @"C:\CanopyPackages\Newtonsoft.Json.6.0.8\lib\net40\"
#I @"C:\Projects\CanopyFalcon\packages\canopy.1.0.6\lib"

#r "WebDriver.Support.dll"
#r "WebDriver.dll"
#r @"C:\Projects\CanopyFalcon\packages\canopy.1.0.6\lib\canopy.dll"

open canopy
open runner
//open OpenQA.Selenium

start chrome

I still get the same error.

[lefthandedgoat]

Can you clone this and see if it works for you?

https://github.com/lefthandedgoat/canopyStarterKit

run build.cmd from the root folder

[lefthandedgoat]

BTW this works for me

#I @"C:\projects\fsxCanopy\packages\Selenium.WebDriver.3.0.0\lib\net40\"
#I @"C:\projects\fsxCanopy\packages\canopy.1.0.6\lib"

#r "WebDriver.dll"
#r "canopy.dll"
    

open canopy
open runner
//open OpenQA.Selenium

start chrome

quit()

Also for latest chrome driver:

[lefthandedgoat]

Did you put your chrome driver in root c:\ (thats the default location)

[navmed]

It was the last thing - I had a chromedriver.exe in c:\ AND in bin/debug for some reason. I had updated the one in bin/debug but it was using the one in the c:\ . Once I updated the one in c:\ it started working. Thank you some much for your help!

[vbop9834]

Insert this line of code in your script right before start chrome or run ()

canopy.configuration.chromeDir <- __SOURCE_DIRECTORY__

The above code looks for the chromedriver in the same folder as the script.

[navmed]

Thanks Jeremy, that's good info to have.

[vbop9834]

Anytime! 😀
