File Detection

Dependi automatically detects dependency files by name:

Cargo.toml        → Rust
package.json      → Node.js
requirements.txt  → Python
pyproject.toml    → Python
go.mod            → Go
composer.json     → PHP
pubspec.yaml      → Dart
*.csproj          → .NET
Gemfile           → Ruby

Version Formats

Each ecosystem has its own version specification format:

Ecosystem Example Meaning
Rust "1.0", "^1.0", "~1.0" Cargo semver
npm "^1.0.0", "~1.0.0", ">=1.0" npm semver
Python ==1.0.0, >=1.0,<2.0 PEP 440
Go v1.0.0, v1.0.0+incompatible Go modules
PHP ^1.0, ~1.0, >=1.0 <2.0 Composer
Dart ^1.0.0, ">=1.0.0 <2.0.0" pub
.NET 1.0.0, [1.0,2.0) NuGet
Ruby ~> 1.0, >= 1.0, < 2.0 Bundler

Dependi understands these formats and extracts the correct version for checking.
