Bit hard to figure out what to type for a local file on windows in installer-url

[moorepants]

I spent quite some time this morning figuring this out as it wasn't obvious from the docs or examples. It may be obvious for a Javascript developer that knows how this works:

// Node program to demonstrate the  
// URL.fileURLToPath() API as Setter 
  
// Importing the module 'url'  
const url = require('url'); 
  
// Some random path from system 
const file = 'file:///C:/path/example/gfg'
   
// Converting the file to properly encoded path 
console.log(url.fileURLToPath(file)) 

which returns:

 C:\path\example\gfg

taken from: https://www.geeksforgeeks.org/node-js-url-fileurltopath-api/

I finally got a local exe to build on a Github action with:

      - uses: conda-incubator/setup-miniconda@v3
        with:
          auto-update-conda: true
          installer-url: file:///D:/r/repoowner/reponame/anaconda-installer-Windows-x86_64.exe

I can also probably remove the full path, but the key things are 1) use forward slashes, even if you are on windows and 2) use three forward slashes after file:.

It could be helpful to give an example of this in the docs of this repo. Thanks for the action!

There is this:

setup-miniconda/.github/workflows/example-5.yml

Line 42 in 3ec85ce

file:///tmp/some-built-installer-${{ github.run_number

but that is on Ubuntu so it wasn't obvious for me what to do on Windows (use forward slashes not backslashes).

One more note is that the path to the file must be absolute. A relative path failed.

I cannot confirm your findings here. I have a running action with the following URL:

installer-url: file://D:\a\helios-installer\helios-installer/dist/helios-2.0.0a1-Windows-x86_64.exe

which does not have triple / and mixed / and \. You find the code here: https://github.com/ssciwr/helios-installer/blob/main/.github/workflows/installer.yml#L102

Here are the various commits that show what I tried: moorepants/anaconda-dee-config#1

It works now, so I will stick with the triple and forward slashes.
