Package Manager (LPM)

Stable LPM is production-ready in Levython 1.0.

LPM (Levython Package Manager) is a native C++ package manager for installing, managing, and removing Levython packages. Unlike other language package managers, LPM requires no external dependencies.

Overview#

LPM can be invoked in two ways:

terminal

# Via levython command
levython lpm <command>

# Or directly
lpm <command>

lpm install <package>#

Install a package:

lpm install <package-name>

terminal

$ lpm install math
Installing math...
✓ Package 'math' installed successfully

$ lpm install tensor
Installing tensor...
✓ Package 'tensor' installed successfully

Packages are installed to ~/.levython/packages/.

lpm remove <package>#

Remove an installed package:

lpm remove <package-name>

terminal

$ lpm remove math
Removing math...
✓ Package 'math' removed successfully

lpm list#

List all installed packages:

lpm list

terminal

$ lpm list
Installed packages:
  • math     - Mathematical functions
  • tensor   - Tensor operations for ML
  • random   - Random number generation

3 packages installed

lpm search [query]#

Search for available packages:

lpm search [query]

terminal

$ lpm search ml
Search results for 'ml':
  • ml       - Machine learning utilities
  • tensor   - Tensor operations for ML

$ lpm search
Available packages:
  • math     - Mathematical functions
  • tensor   - Tensor operations
  • ml       - Machine learning utilities
  • random   - Random number generation
  • test     - Testing framework
  • string   - String manipulation
  • json     - JSON parsing
  • http     - HTTP client/server
  • csv      - CSV file handling

Available Packages#

The following packages are available through LPM:

Package	Description	Status
`math`	Advanced mathematical functions (sin, cos, sqrt, pow, etc.)	Stable
`tensor`	Tensor creation and operations for machine learning	Stable
`ml`	Machine learning utilities and helpers	Stable
`random`	Random number generation and sampling	Stable
`test`	Testing framework with assertions	Stable

Using Installed Packages

Once installed, packages are automatically available in your Levython programs. For example, after installing math:

levython

# After: lpm install math

pi <- 3.14159
radius <- 5

area <- pi * radius * radius
say("Circle area: " + str(area))
