StringsLint

A tool to ensure localized strings are complete and never unused.

StringsLint hooks into your source files, specifically it scans:

• .strings and .stringsdict
• .swift and .m
• .xib and .storyboard

If you found a bug or have a feature request, please open an issue. If you want to contribute, submit a pull request.

Installation

Using Mint:

mint install dral3x/stringslint

Using Homebrew

brew tap dral3x/dral3x
brew install stringslint

Using CocoaPods:

Simply add the following line to your Podfile:

pod 'StringsLint'

This will download the StringsLint binaries and dependencies in Pods/ during your next pod install execution and will allow you to invoke it via ${PODS_ROOT}/StringsLint/stringslint in your Script Build Phases.

This is the recommended way to install a specific version of StringsLint since it supports installing a pinned version rather than simply the latest (which is the case with Homebrew and Mint).

Note that this will add the StringsLint binaries, its dependencies' binaries and the Swift binary library distribution to the Pods/ directory, so checking in this directory to SCM such as git is discouraged.

Compiling from source:

You can build from source by cloning this project and running make install (Xcode 10.0 or later).

Usage

Xcode

Integrate StringsLint into an Xcode scheme to get warnings and errors displayed in the IDE. Just add a new "Run Script Phase" with:

if which stringslint >/dev/null; then
  stringslint
else
  echo "warning: StringsLint not installed, download from https://github.com/dral3x/StringsLint"
fi

Alternatively, if you've installed StringsLint via CocoaPods the script should look like this:

"${PODS_ROOT}/StringsLint/stringslint"

Command Line

$ stringslint help
OVERVIEW: A tool to enforce Swift style and conventions.

USAGE: stringslint <subcommand>

OPTIONS:
  --version               Show the version.
  -h, --help              Show help information.

SUBCOMMANDS:
  lint (default)          Print lint warnings and errors (default command)
  version                 Display the current version of StringsLint

  See 'stringslint help <subcommand>' for detailed help.

Run stringslint in the directory containing the files to lint. Directories will be searched recursively.

GitHub Action

Create a new workflow file in your repo (for example: .github/workflows/stringslint.yml) with the following content:

name: StringsLint

on:
  pull_request:
    paths:
      - '.github/workflows/stringslint.yml'
      - '.stringslint.yml'
      - '**/*.swift'
      - '**/*.strings'
      - '**/*.stringsdict'

jobs:
  StringsLint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2

      - name: GitHub Action for StringsLint
        uses: dral3x/[email protected]

Rules

There are few basic but important rules included. See Rules.md for more information.

You can also check Sources/StringsLintFramework/Rules/Lint directory to see their implementation.

Each rule can emit violations. You can configure the severity of these violations (accepted values are none, warning and error).

When a violation with severity error is emitted, the Xcode build will fail.

Configuration

Configure StringsLint by adding a .stringslint.yml file from the directory you'll run StringsLint from. You can configure included and excluded file paths, extends some parsers capabilities and even turn off rules or specific files for each rule:

included: # paths to include during linting. `--path` is ignored if present.
  - Source
excluded: # paths to ignore during linting. Takes precedence over `included`.
  - Carthage
  - Pods
  - Source/ExcludedFolder
  - Source/ExcludedFile.swift
  - Source/*/ExcludedFile.swift # Exclude files with a wildcard

# Customize parsers
objc_parser:
  implicit_macros:
    - SPKLocalizedString # detect this custom macro

xib_parser:
  key_paths:
    - textLocalized # keyPath used to localized UI elements

swift_parser:
  swiftui_implicit: false # disable implicit detection of SwiftUI localized strings

# Customize specific rules
missing:
  severity: error
  ignored:
    - Demo title

partial:
  severity: warning

unused:
  severity: note
  ignored:
    - NSAppleMusicUsageDescription # used by iOS directly

missing_comment:
  severity: none
