The original version of this project can be found at subalfred check features
.
Upon further investigation, I have found that this tool is not only compatible with Substrate projects but also works for general Cargo projects, offering even more powerful features than before.
Now, cargo-featalign
stands out with its enhanced functionality.
The cargo-featalign
tool offers the following features:
- Checking for missing features
- Printing the dependency path
- Performing a dry run before overwriting
- Automatically aligning/fixing missing features
- Sorting alphabetically while aligning
- From GitHub:
github.com/hack-ink/cargo-featalign/releases/latest
- From Cargo:
cargo install cargo-featalign
cargo featalign --help
Cargo features alignment tool.
Usage: cargo-featalign [OPTIONS] --features <[NAME]> [PATH]
Arguments:
[PATH]
Root `Cargo.toml`'s path.
If `Cargo.toml` is not provided, it will be searched for under the specified path.
[default: ./Cargo.toml]
Options:
--features <[NAME]>
Features to process
--thread <NUM>
Number of threads to use.
The default value is based on the number of logical cores.
[default: 32]
--mode <MODE>
Running mode.
Check: Prints the analysis result.
DryRun: Prints the resolved result without modifying the `Cargo.toml` file.
DryRun2: creates a `*.cargo-featalign.swap` file.
Overwrite: Overwrites the original `Cargo.toml` file.
[default: overwrite]
[possible values: check, dry-run, dry-run2, overwrite]
--indent-symbol <INDENT_SYMBOL>
Use the given symbol for indentation
[default: tab]
[possible values: tab, whitespace]
--indent-size <SIZE>
The number of spaces used for indentation
[default: 4]
--workspace-only
Determines whether to process only workspace members
--default-std
Determines whether to check default features.
This option is useful when working in a no-std environment. This feature checks if you have set `default-features = false` while also having a `std = ["x/std"]` part to control it separately.
--depth <NUM>
Depth of the dependency tree to process.
Use `-1` to process the entire tree.
!! Running with this flag under a large project, even with 128 threads configured, is incredibly challenging.
[default: 0]
--sort
Wether to sort the required features while aligning
--verbose
Verbose output
-h, --help
Print help (see a summary with '-h')
-V, --version
