A source code analyzer for Swift projects.
Sitrep is a source code analyzer for Swift projects, giving you a high-level overview of your code:
Behind the scenes, Sitrep captures a lot more information that could be utilized – how many functions you have, how many comments (regular and documentation), how large your enums are, and more. These aren’t currently reported, but could be in a future release. It’s also written as both a library and an executable, so it can be integrated elsewhere as needed.
Sitrep is built using Apple’s SwiftSyntax, which means it parses Swift code accurately and efficiently. Make sure that SwiftSyntax version specified in Package.swift matches your current Swift tools version (i.e. if you're using Swift tools 5.2 you need to update spec from
Use this command for Homebrew:
brew install twostraws/brew/sitrep
Using Homebrew allows you to run
sitrep directly from the command line.
For Mint, install and run Sitrep with these command:
mint install twostraws/Sitrep@main mint run sitrep@main
And finally, to build and install the command line tool yourself, clone the repository and run
git clone https://github.com/twostraws/Sitrep cd Sitrep make install
As with the Homebrew option, building the command line tool yourself allows you to use the
sitrep command directly from the command line.
Sitrep is implemented as a library that does all the hard work of scanning and reporting, plus a small front end that handles reading and writing on the command line. As an alternative to using Sitrep from the command line, you can also use its library SitrepCore from inside your own Swift code.
First, add Sitrep as a dependency in your
let package = Package( //... dependencies: [ .package(url: "https://github.com/twostraws/Sitrep", .branch("master")) ], //... )
import SitrepCore wherever you’d like to use it.
When run on the command line without any flags, Sitrep will automatically scan your current directory and print its findings as text. To control this behavior, Sitrep supports several command line flags:
-clets you specify a path to your .sitrep.yml configuration file, if you have one.
-fsets the output format. For example,
-f jsonenables JSON output. The default behavior is text output, which is equivalent to
-iwill print debug information, showing the settings Sitrep would use if a real scan were requested, then exits.
-psets the path Sitrep should scan. This defaults to your current working directory.
-hprints command line help.
You can customize the behavior of Sitrep by creating a .sitrep.yml file in the directory you wish to scan. This is a YAML file that allows you to provide permanent options for scanning this path, although right now this is limited to one thing: an array of directory names to exclude from the scan.
For example, if you wanted to exclude the .build directory and your tests, you might create a .sitrep.yml file such as this one:
excluded: - .build - Tests
You can ask Sitrep to use a custom configuration file using the
-c parameter, for example
sitrep -c /path/to/.sitrep.yml -p /path/to/swift/project.
Alternatively, you can use the
-i parameter to have Sitrep tell you the configuration options it would use in a real analysis run. This will print the configuration information then exit.
Sitrep is written using Swift 5.3. You can either build and run the executable directly, or integrate the SitrepCore library into your own code.
To build Sitrep, clone this repository and open Terminal in the repository root directory. Then run:
swift build swift run sitrep -p ~/path/to/your/project/root
If you would like to keep a copy of the
sitrep executable around, find it in the
.debug directory after running
To run Sitrep from the command line just provide it with the name of a project directory to parse – it will locate all Swift files recursively from there. Alternatively, just using
sitrep by itself will scan the current directory.
Any help you can offer with this project is most welcome, and trust me: there are opportunities big and small, so that someone with only a small amount of Swift experience can help.
Some suggestions you might want to explore:
Please ensure you write tests to accompany any code you contribute, and that SwiftLint returns no errors or warnings.
