LINVAST Python podrška

Python podrška proširuje LINVAST novim builderom koji prevodi Python izvorni kod u zajednički LINVAST AST model.

Prevođenje i pokretanje

Komande se pokreću iz korena repozitorijuma.

Potrebni alati:

• .NET SDK sa podrškom za net5.0 i netstandard2.1
• Docker, opciono, za pokretanje testova bez lokalno instaliranog .NET SDK-a

ANTLR C# fajlovi za Python parser su već generisani u direktorijumu LINVAST.Imperative/Builders/Python/ANTLR.

Prevođenje projekta:

dotnet restore LINVAST.sln
dotnet build LINVAST.sln

Release build:

dotnet build LINVAST.sln -c Release

Korišćenje

Python builder je registrovan za .py fajlove, pa se može koristiti preko ImperativeASTFactory.

using System;
using LINVAST.Imperative;
using LINVAST.Nodes;

ASTNode ast = new ImperativeASTFactory().BuildFromFile("sample.py");

Console.WriteLine(ast.GetText());
Console.WriteLine(ast.ToJson(compact: false));

Primeri

Deklaracije i tuple unpacking

count: int = 1
a, *rest = 1, 2, 3, 4
count = count + 1

Funkcije, anotacije i dekoratori

@trace
def add(x: int, y: int = 0) -> int:
    return x + y

Kontrola toka

try:
    value = load()
except ValueError as error:
    value = 0
else:
    value = value + 1
finally:
    cleanup()

Pattern matching

match value:
    case [first, *rest] if first > 0:
        result = first
    case _:
        result = 0

Comprehension i f-string

squares = {x: x ** 2 for x in range(1, 6)}
message = f"count={len(squares)}"

Testovi

Python testovi se nalaze u LINVAST.Tests/Imperative/Builders/Python/:

• ExpressionTests.cs
• DeclarationTests.cs
• FunctionTests.cs
• ClassTests.cs
• ControlFlowTests.cs
• PatternTests.cs
• ImportTests.cs
• BlockTests.cs
• BuildingErrorTests.cs

Pokretanje svih testova:

dotnet test LINVAST.sln

Pokretanje samo Python testova:

dotnet test LINVAST.Tests/LINVAST.Tests.csproj --filter "FullyQualifiedName~Python"

Pokretanje samo Python testova u Docker kontejneru:

docker run --rm -v "$PWD":/workspace -v /tmp/linvast-nuget:/root/.nuget/packages -w /workspace mcr.microsoft.com/dotnet/sdk:5.0 dotnet test LINVAST.Tests/LINVAST.Tests.csproj --nologo --filter "FullyQualifiedName~Python"

Pokretanje svih testova u Docker kontejneru:

docker run --rm -v "$PWD":/workspace -v /tmp/linvast-nuget:/root/.nuget/packages -w /workspace mcr.microsoft.com/dotnet/sdk:5.0 dotnet test LINVAST.Tests/LINVAST.Tests.csproj --nologo
