packaging: WinGet and Chocolatey packages for the window and the command line - #143
Conversation
…and line Two programs ship in two archives, so each becomes a package of its own in both feeds: DonislawDev.TestingFilesGenerator and .CLI in WinGet, testing-files-generator and testing-files-generator-cli in Chocolatey. The templates in packaging/ hold the shape. .github/scripts/build_packages.py fills them from the one place each value lives - the tag, the release's own checksum file, go.mod, web/public/CNAME and CHANGELOG.md - and refuses the inputs that would render and be wrong: another release's checksums, a release candidate, a missing archive, an unreleased version, a destination inside the repository or one that already holds something, and a value that would break the file it lands in. It renders beside the destination and renames at the end, so a refusal leaves nothing behind. Sixteen guards hold what a reviewer cannot catch: both WinGet packages keep the program beside its files, the command line offers both architectures, every download is an archive the release builds and is checked against its checksum, the icon is a CDN address pinned to the tag, the window's shim does not hold the terminal and its shortcut starts where a person can write, no package script ends a running program, and every script is ASCII.

…k what happened The packaging guards check that the lines which matter are there. This job asks whether the install works: it renders both Chocolatey packages from the latest published release, installs them from the release's own archives, and checks that tfg answers with the version through its shim, that the tfg-gui shim does not wait, that the software renderer lies beside the window and that the Start menu shortcut starts in the user's profile. Then it removes them, checks that the shims and files went with them, that a shortcut of somebody else's under the same name was left alone, and that the package's own shortcut goes when nothing else claims it. WinGet is not on the runner image, so both WinGet manifests are validated and installed on a virtual machine before each submission instead. The two guards that start the renderer carry a nosemgrep note with the reason: the interpreter comes from PATH and every argument is a value the guard chose.

344-368:os.renameonto an existing emptyouthas a race, and a Ctrl+C can leave the destination missing.Line 367 removes an existing empty
out, and Line 368 then renamesworkonto that path. Suppose the rename fails after thermdir. Examples are a cross-device parent, which is impossible here, or a concurrent writer. In that case the directory the user passed no longer exists. On Windows,os.renamealso fails when the target exists. Thermdircovers that case, but it leaves a window between the two calls. The impact is small. You can keep the code as it is, or useos.replace(work, out)afterrmdirto get the same semantics with one intent.

15-20: The CLI Chocolatey package installs x64 on arm64 machines.The package passes only
-Url64bit. Chocolatey then installs the amd64tfg.exeon Windows arm64, where it runs under emulation. WinGet ships a native arm64 installer for the same package, so the two feeds give different binaries on the same machine. The renderer already hasnames["arm64"]for the CLI. There are two fixes:
- Add an arm64 branch that uses
$env:PROCESSOR_ARCHITECTURE -eq 'ARM64'with its own URL and checksum placeholders.- Or state in the README that the Chocolatey CLI package is amd64-only on purpose.
The README table says "and
arm64in WinGet", so the difference is documented. That makes this a design gap, not a hidden bug. I am skipping it as intended behaviour..github/workflows/ci.yml (1)

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
If TargetPath is null, the uninstall throws, and the shortcut check is skipped.
When CreateShortcut succeeds but TargetPath is $null, $target becomes $null. This can happen with a shortcut that targets a shell namespace item. Line 30 then calls $null.StartsWith(...), which is a method-call-on-null error. With $ErrorActionPreference = 'Continue' this is a non-terminating error. The if is evaluated as false, so the shortcut is left alone, which is the safe outcome. The script still prints an error, which the header says it must not do. Coerce the value to a string:

…and the README counts 26 formats An outside review of #143 said a shortcut's target can be null and would make the uninstall print an error. Measured on the machine this was written on, none of the 447 Start menu shortcuts answered with no value - 8 answered with an empty path, the shell items like File Explorer and the Recycle Bin, and a shortcut made to a shell item answers the same. The empty answer is harmless to the check, but the sentence built from it read "It points at , not at this package". It now says the shortcut points at no file. The CI job makes such a shortcut under the package's name, uninstalls, and reads both messages. The README said "24 formats" and "24 real formats" while the program ships 26. The count in words above the formats table had been raised by hand for the release and these two had not, because nothing compared them with anything. TestTheReadmeCountsTheFormatsItShips now holds every count the README writes in digits to the registry. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Package sources for WinGet and Chocolatey, rendered for the published
v0.4.0. Nothing is submitted by this pull request - submitting stays a person's step.Four packages, two per feed
DonislawDev.TestingFilesGeneratorDonislawDev.TestingFilesGenerator.CLI(x64 and arm64)testing-files-generatortesting-files-generator-clitfg-guitfgThe two programs ship in two archives and the window carries the same engine, so each package stands alone: a build agent takes the command line without the window, and one package waiting in moderation does not hold the other.
How to see it
writes the three WinGet files per package in the
winget-pkgslayout, and both Chocolatey package folders. Thenwinget validate --manifest <folder>andchoco pack <nuspec>answer for them.What carries it
ArchiveBinariesDependOnPath: true. Without it WinGet reaches the program through a symbolic link, and the window started that way looks for its software renderer beside the link instead of in theopenglfolder beside the real file. With it the package's folder goes onPATH. Read in winget-cli'sPortableInstaller.cpp, which also falls back toPATHwhen a link cannot be made, so without the field the command line's shape would depend on whether the machine allows symbolic links.tfg-gui.exe.guilies beside the program.%USERPROFILE%. The window offers atfg-outfolder under the directory it was started from, and the package folder is one an ordinary account cannot write to. The variable is stored as written and expanded when the shortcut starts - measured. The uninstall removes that shortcut only when it points into the package.chocolateybeforemodify.ps1says the program is running and leaves closing it to the person.go.mod,web/public/CNAME,CHANGELOG.md. The product name and the licence are held to their Go originals by a guard.What refuses
The renderer refuses, by name, another release's checksums, a release candidate, a missing archive, a version the changelog never released, a destination inside the repository or one that already holds something, and a value that would break the file it lands in. It renders beside the destination and renames at the end, so a refusal or an interruption leaves nothing behind.
