feat(registry): Add imagemagick github backend entry for Windows binary releases

[iki]

Follow-up to #8386 discussion on imagemagick, where #8388 fixed the message and this PR aims to add a github binary releases backend to imagemagick registry entry to allow installing on Windows.

Currently, I'm able to install imagemagick on Windows from its binary releases on https://github.com/ImageMagick/ImageMagick/releases using the following entry in ~/.config/mise/config.toml:

"github:ImageMagick/ImageMagick" = { version = "latest", os = ["windows"], platforms = { windows-x64 = { asset_pattern = "ImageMagick-*-portable-Q16-HDRI-x64.7z" }, windows-x86 = { asset_pattern = "ImageMagick-*-portable-Q16-HDRI-x86.7z" }, windows-arm64 = { asset_pattern = "ImageMagick-*-portable-Q16-HDRI-arm64.7z" } } }

Here's an attempt to define that backend in registry/imagemagick.toml:

description = "ImageMagick is a free, open-source software suite for creating, editing, converting, and displaying images. It supports 200+ formats and offers powerful command-line tools and APIs for automation, scripting, and integration across platforms"
test = { cmd = "magick --version 2>&1", expected = "ImageMagick" }

[[backends]]
full = "conda:imagemagick"

[[backends]]
full = "asdf:mise-plugins/mise-imagemagick"

[[backends]]
full = "github:ImageMagick/ImageMagick"
os = ["windows"]
platforms = ["windows-x64", "windows-x86", "windows-arm64"]

[backends.options.platforms.windows-x64]
asset_pattern = "ImageMagick-*-portable-Q16-HDRI-x64.7z"

[backends.options.platforms.windows-x86]
asset_pattern = "ImageMagick-*-portable-Q16-HDRI-x86.7z"

[backends.options.platforms.windows-arm64]
asset_pattern = "ImageMagick-*-portable-Q16-HDRI-arm64.7z"

Is there any way how to test it locally @jdx?

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the mise registry by introducing support for installing ImageMagick on Windows operating systems. It configures a new GitHub backend that points to ImageMagick's official binary releases, allowing users to seamlessly install the tool with platform-specific asset patterns for various Windows architectures.

Highlights

• ImageMagick Windows Support: Added a new GitHub backend entry to the imagemagick registry, specifically enabling installation of ImageMagick on Windows via its official GitHub binary releases.
• Configuration Structure Update: Refactored the backends definition in registry/imagemagick.toml from a single array to an array of tables ([[backends]]) to accommodate detailed platform-specific asset patterns for the new GitHub backend.

Changelog

• registry/imagemagick.toml
  • Added a new github:ImageMagick/ImageMagick backend entry.
  • Specified os = ["windows"] and platforms = ["windows-x64", "windows-x86", "windows-arm64"] for the GitHub backend.
  • Defined asset_pattern for windows-x64, windows-x86, and windows-arm64 platforms to correctly identify the portable 7z archives.
  • Converted the backends definition from a simple array to an array of tables to support the new detailed backend configuration.

Activity

• The author, iki, initiated this PR as a follow-up to a discussion on imagemagick (Error: imagemagick not found in mise tool registry #8386) and a related fix (fix(install): improve error when registry tool has no supported backends #8388).
• The author posed a question to @jdx regarding local testing of the new backend configuration.

Code Review

This pull request successfully adds a GitHub backend entry for ImageMagick, enabling installation on Windows by specifying platform-specific asset patterns. The changes correctly refactor the backends definition from a simple array to an array of tables, which is necessary to support the detailed platform options. The TOML syntax is correct and aligns with the intended functionality for handling GitHub binary releases.

Greptile Summary

This PR adds a github:ImageMagick/ImageMagick backend entry to the imagemagick registry so that mise can install ImageMagick on Windows directly from GitHub binary releases, while also converting the file to the modern [[backends]] table format.

Key points:

• The platforms = ["windows"] filter on the new backend is correct — it matches against std::env::consts::OS ("windows") in registry.rs.
• The [backends.options.platforms] block with inline tables is functionally equivalent to the per-heading style ([backends.options.platforms.windows-x64]) used everywhere else in the registry, but is inconsistent with convention.
• The windows-x86 (32-bit) platform entry that appeared in the original PR description was dropped without explanation — on a 32-bit Windows host the backend will fall through to auto-detection and likely fail to select the correct asset.
• No windows-x86 entry in the TOML means 32-bit Windows users will not benefit from this change.

Confidence Score: 3/5

• Safe to merge for most Windows users (x64 and arm64), but 32-bit Windows support is silently dropped compared to the original proposal.
• The core logic is sound — the OS filter and asset-pattern lookup will work correctly on Windows x64 and arm64. The two remaining concerns are a style inconsistency (inline vs. per-heading table format) and the undocumented removal of the windows-x86 entry. Neither blocks the PR for the common case, but the x86 gap is a silent regression from the stated goals.
• registry/imagemagick.toml — platform options format and missing windows-x86 entry.

Important Files Changed

Filename	Overview
registry/imagemagick.toml	Migrates backends from an inline array to the structured [[backends]] table format and adds a Windows-only github:ImageMagick/ImageMagick backend with platform-specific asset patterns; the filtering logic is correct but the options format differs from the registry convention and windows-x86 support from the original proposal is missing.

Code Review

This pull request adds a GitHub backend for ImageMagick to support Windows binary releases. The implementation is functionally correct, but I've suggested an improvement to the TOML configuration to make it more readable and maintainable by grouping related platform options.

Code Review

This pull request adds a GitHub backend for imagemagick to support installation on Windows. The changes to registry/imagemagick.toml correctly refactor the backends definition to an array of tables and add the new GitHub backend. However, there is an issue with one of the platform keys used, which violates the registry schema as detailed in the comment.

Code Review

This pull request adds a GitHub backend for ImageMagick on Windows, allowing for direct installation of binary releases. The changes correctly restructure the imagemagick.toml file to accommodate the new backend. My review includes a suggestion to add support for the windows-x86 architecture, which appears to be available in the releases but was missed in the current implementation.

I think it might be best to try to get this into aqua registry instead

[suchipi]

Could we get this in the meantime until it's added to aqua registry? My netlify builds are taking a long time because I need imagemagick and they don't give me access to the system package manager but they have mise so I install imagemagick with mise on Linux as part of my build but it takes a long time to install because it has to compile from source.

[iki]

@suchipi: It is already in aqua registry since aquaproj/aqua-registry#50281, you can use mise use aqua:ImageMagick/ImageMagick on Windows with current mise v2026.6.1 with aqua 7z support #10224

For updating mise registry see current #10118

[suchipi]

thank you!

[iki]

@suchipi: Actually on Linux it doesn't work yet as mise does not support AppImage archives currently: #10118 (comment)

It may be unblocked by ImageMagick adding static Linux build archive: ImageMagick/ImageMagick#8792

In meantime, you may try to install aqua and use it to install ImageMagick, it works on Windows:

mise use -g aqua
aqua g -i ImageMagick/ImageMagick && aqua i
