Review Change Stack

📝 Walkthrough

Walkthrough

The PR adds shfmt-based formatting and validation for multiline mise task bodies, reformats shell commands across mise configurations, documents the workflow, and updates the pic-viewer favicon test to derive dimensions from embedded PNG metadata.

Changes

Mise shell formatting

Layer / File(s) Summary
Mise task-body formatter
.mise/shfmt-mise.awk, .mise/config.toml, CLAUDE.md
Adds AWK-based extraction and merge handling for multiline task bodies, shfmt tasks and options, formatter dependencies, validation wiring, and usage documentation.
Mise configuration formatting
.mise/config*.toml
Reformats coverage, build, maintenance, prerequisite, checksum, generation, and release shell commands. The summaries report unchanged command behavior.

Favicon test dimensions

Layer / File(s) Summary
PNG-derived favicon assertions
services/ws-modules/pic-viewer/tests/show_image.rs
The test derives favicon dimensions from the embedded PNG IHDR header and checks the calculated center pixel instead of fixed coordinates.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔴 Critical · up to 87788

The formatting changes currently include a compile error in the image viewer tests and could also leave configuration files partially written or fail on supported hosts due to command and tool-detection issues. The PR is not ready to merge until these problems are corrected.

Set the Homebrew-check command for binutils.

The first case assigns cmd="" to binutils, but the second case verifies as. The later empty-command guard skips the Homebrew path check for as. Set cmd=as for binutils; otherwise a Homebrew assembler can pass this prerequisite check.

Use mise-managed utilities in the Windows PATH rewrite.

Lines 307 and 312 invoke bare tr, grep, paste, and head. Replace them with provisioned commands, such as coreutils and rg, so the task does not fail on hosts without those utilities.

Use repository-managed commands in this mise task.

This changed command calls bare tr, grep, and paste. A mise task must not assume that these utilities exist on the host. Use repository-managed equivalents, such as coreutils tr, rg, and coreutils paste, or use a shell-only implementation.

As per coding guidelines, “A mise task must never assume a command-line utility happens to exist on the host.”

Use atomic replacement for each formatted configuration.

Line 991 copies directly over "$cfg". coreutils cp truncates the destination before it finishes writing. If the copy fails or the task is interrupted, it can leave a partial .mise/config*.toml file.

Write a temporary file beside the destination, then rename it after the copy succeeds.

fix. Its one demand on how a body is written: inside a `"""` block every backslash escape must be doubled, since a
lone `\n` / `\r` / `\b` is TOML syntax that folds into a control character rather than the two bytes the shell wants

Correct the supported escape rule.

The text says every backslash escape must be doubled. .mise/shfmt-mise.awk accepts \" and decodes it to a quote. State that a backslash intended to reach Bash must be doubled, while \" remains supported TOML syntax.

web-sys 0.3.103 CanvasRenderingContext2d get_image_data Rust signature

💡 Result:

In web-sys version 0.3.103, the Rust signature for the get_image_data method on the CanvasRenderingContext2d struct is: pub fn get_image_data(&self, sx: i32, sy: i32, sw: i32, sh: i32) -> Result<ImageData, JsValue> To use this method, you must ensure that both "CanvasRenderingContext2d" and "ImageData" are enabled in your Cargo.toml file under the web-sys features [1][2]. Additionally, this API requires the use of nightly Rust with the --cfg=web_sys_unstable_apis flag for compilation if it is marked as unstable in your specific environment [1][2]. Note that while earlier versions of web-sys (such as 0.3.55 and older) defined the parameters as f64 [3][4], the signature in version 0.3.103 uses i32 [1][5].

Citations:


Pass integer coordinates to get_image_data.

web-sys 0.3.103 requires four i32 arguments. The current f64 arguments cause a compile error.
