# Author: Miodrag Milic <miodrag.milic@gmail.com> # Last Change: 22-Feb-2017. <# .SYNOPSIS Get Latest URL32 and/or URL64 into tools directxory. .DESCRIPTION This function will download the binaries pointed to by $Latest.URL32 and $Latest.URL34. The function is used to embed binaries into the Chocolatey package. The function will keep original remote file name but it will add suffix _x32 or _x64. This is intentional because you can use those to match particular installer via wildcards, e.g. `gi *_x32.exe`. #> function Get-RemoteFiles { param ( # Delete existing file having $Latest.FileType extension. # Otherwise, when state of the package remains after the update, older installers # will pile up and may get included in the updated package.

Suffixes _x32/_x64 are added. # Use this parameter if remote URL doesn't contain file name but generated hash. [string] $FileNameBase, # By default last URL part is used as a file name.
