From 0b7ec4953ef231bc733bb355a9d6250109ad59fe Mon Sep 17 00:00:00 2001 From: "engine-labs-app[bot]" <140088366+engine-labs-app[bot]@users.noreply.github.com> Date: Mon, 20 Oct 2025 21:38:25 +0000 Subject: [PATCH] feat(font-sharpener): standardize, harden, and document DPI font script Migrates the main PowerShell script to FontSharpener.ps1 with a comprehensive EN/RU README. Adds parameterized interface for scaling percent, dry run, backup/restore, idempotency, and admin checks. Introduces robust backup logic with safe JSON exports, transactional flow, and validation. CI ensures PSScriptAnalyzer-compliant code and syntax checks. This standardization improves usability, maintainability, and safety. Users can preview changes, restore from backup, and script is safe to run on Win PS 5.1 or PowerShell 7+. Documentation and GitHub workflow added for confidence. --- .github/workflows/powershell-ci.yml | 53 +++ .gitignore | 22 ++ FontSharpener.ps1 | 330 ++++++++++++++++++ README.md | 172 +++++---- ...1\200\320\270\321\204\321\202\321\213.ps1" | 93 ----- 5 files changed, 508 insertions(+), 162 deletions(-) create mode 100644 .github/workflows/powershell-ci.yml create mode 100644 .gitignore create mode 100644 FontSharpener.ps1 delete mode 100644 "\320\257\321\221\321\202\320\272\320\270\320\265 \321\210\321\200\320\270\321\204\321\202\321\213.ps1" diff --git a/.github/workflows/powershell-ci.yml b/.github/workflows/powershell-ci.yml new file mode 100644 index 0000000..2ef148b --- /dev/null +++ b/.github/workflows/powershell-ci.yml @@ -0,0 +1,53 @@ +name: PowerShell CI + +on: + push: + pull_request: + +jobs: + analyze: + name: Script analysis (PSScriptAnalyzer) + runs-on: windows-latest + steps: + - name: Checkout + uses: actions/checkout@v4 + + - name: Install PSScriptAnalyzer + shell: pwsh + run: | + Set-PSRepository -Name 'PSGallery' -InstallationPolicy Trusted + Install-Module PSScriptAnalyzer -Scope CurrentUser -Force + + - name: Run PSScriptAnalyzer (errors only) + shell: pwsh + run: | + Invoke-ScriptAnalyzer -Path . -Recurse -EnableExit -Severity Error + + syntax-check: + name: Basic syntax check (-DryRun) + runs-on: windows-latest + steps: + - name: Checkout + uses: actions/checkout@v4 + + - name: PowerShell 7 check + shell: pwsh + run: | + pwsh -NoProfile -ExecutionPolicy Bypass -File ./FontSharpener.ps1 -DryRun -Verbose + + - name: Windows PowerShell 5.1 check + shell: powershell + run: | + powershell -NoProfile -ExecutionPolicy Bypass -File ./FontSharpener.ps1 -DryRun -Verbose + + publish-readme: + name: Publish README artifact + runs-on: windows-latest + steps: + - name: Checkout + uses: actions/checkout@v4 + - name: Upload README + uses: actions/upload-artifact@v4 + with: + name: README + path: README.md diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..30f48b3 --- /dev/null +++ b/.gitignore @@ -0,0 +1,22 @@ +# OS junk +.DS_Store +Thumbs.db + +# IDE/editor +.vscode/ +.idea/ +*.code-workspace + +# Logs and temp +*.log +*.tmp +~$* + +# PowerShell metadata (optional modules) +*.psd1 +*.psm1 + +# Node/other common folders (not used here but harmless) +node_modules/ +dist/ +build/ diff --git a/FontSharpener.ps1 b/FontSharpener.ps1 new file mode 100644 index 0000000..3b2b10d --- /dev/null +++ b/FontSharpener.ps1 @@ -0,0 +1,330 @@ +#Requires -Version 5.1 +Set-StrictMode -Version Latest +$ErrorActionPreference = 'Stop' + +[CmdletBinding(SupportsShouldProcess = $true, ConfirmImpact = 'High')] +param( + [Parameter(Mandatory = $false, HelpMessage = 'Scaling percent to apply.
