From bd706a2710674b1736b4ef494847c639ff6ce481 Mon Sep 17 00:00:00 2001 From: Gilbert Sanchez Date: Fri, 12 Jun 2026 17:32:46 -0700 Subject: [PATCH] fix: FileDownload cross-platform support and target-path handling (#98, #49) - Expand PSDependMap.psd1 Supports to include core/macos/linux; no Windows-only code was blocking cross-platform use (#98) - Root relative Target paths against $PWD before any path operations so callers are not burned by Split-Path against a relative string (#49) - Replace parent-exists heuristic with file-extension check to distinguish file targets from container targets; directory targets are now created when they do not yet exist rather than erroring (#49) - Fix hardcoded ";" path separator in Write-Verbose to use [IO.Path]::PathSeparator for correctness on non-Windows - Add four tests: existing-dir target, new-dir creation, extension-based file-path target, and relative target rooted against $PWD Co-Authored-By: Claude Sonnet 4.6 --- CHANGELOG.md | 9 +++++ PSDepend/PSDependMap.psd1 | 2 +- PSDepend/PSDependScripts/FileDownload.ps1 | 39 +++++++++++++-------- Tests/FileDownload.Type.Tests.ps1 | 41 +++++++++++++++++++++++ 4 files changed, 76 insertions(+), 15 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index fb01fbc..586b088 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -7,6 +7,15 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 ## [Unreleased] +### Added + +- `FileDownload` is now supported on all platforms (`core`, `macos`, `linux`); there was no Windows-only code blocking this (#98). +- `FileDownload` relative `Target` paths are now rooted against `$PWD` before resolution, matching the intuitive expectation of callers (#49). + +### Fixed + +- `FileDownload` no longer misidentifies a directory-like `Target` (no file extension, or trailing slash) as a full file path when its parent happens to exist; the handler now uses a file-extension heuristic to distinguish file targets from container targets and creates the directory when it does not yet exist (#49). + ## [0.4.1] - 2026-06-12 ### Added diff --git a/PSDepend/PSDependMap.psd1 b/PSDepend/PSDependMap.psd1 index e152a53..98d282f 100644 --- a/PSDepend/PSDependMap.psd1 +++ b/PSDepend/PSDependMap.psd1 @@ -27,7 +27,7 @@ FileDownload = @{ Script = 'FileDownload.ps1' Description = 'Download a file' - Supports = 'windows' + Supports = 'windows', 'core', 'macos', 'linux' } FileSystem = @{ diff --git a/PSDepend/PSDependScripts/FileDownload.ps1 b/PSDepend/PSDependScripts/FileDownload.ps1 index 9136344..a413954 100644 --- a/PSDepend/PSDependScripts/FileDownload.ps1 +++ b/PSDepend/PSDependScripts/FileDownload.ps1 @@ -76,15 +76,16 @@ Write-Verbose "Using URL: $URL" # Act on target path.... $ToInstall = $False # Anti pattern + +# Normalize relative paths against $PWD so callers don't get burned by cwd-dependent splits +if (-not [IO.Path]::IsPathRooted($Target)) { + $Target = Join-Path $PWD $Target +} + $TargetParent = Split-Path $Target -Parent $PathToAdd = $Target -if ( (Test-Path $TargetParent) -and -not (Test-Path $Target)) { - # They gave us a full path, don't parse the file name, use this! - $Path = $Target - $ToInstall = $True - Write-Verbose "Found parent [$TargetParent], not target [$Target], assuming this is target file path" -} -elseif (Test-Path $Target -PathType Leaf) { + +if (Test-Path $Target -PathType Leaf) { # File exists.
