(on the command line)

LPeter1997•3mo ago

--configuration Release?

it’s raining outsideOP•3mo ago

always run

so i dont need to add those extra arguments it's just an in-built setting

LPeter1997•3mo ago

Shove it in a script and call ./build.ps1 🤷 I don't recommend defaulting to release anyway, not a lot of win. Most of the time you'll only need a release build when publishing to save on PDB size I'm 99% sure you could do some hackery like

<PropertyGroup Condition="'$(Configuration)' == ''">
    <Configuration>Release</Configuration>
</PropertyGroup>

<PropertyGroup Condition="'$(Configuration)' == ''">
    <Configuration>Release</Configuration>
</PropertyGroup>

But Idk about that, not an MSBuild expert to say that this will actually do what you want

not an MSBuild expert

is there anyone here who is?

LPeter1997•3mo ago

My question would be, why do you insist on local Release builds

it’s raining outsideOP•3mo ago

im writing a chess engine and when i do something called a "perft test" (make a function that traverses the game tree and verifies your code works fine), i got about 50,000 nodes per second (extremely slow, i was seeing people get hundreds of millions of nodes per second) and thats because i was (unknowingly) running it in debug mode. running it in release got me 12-18mnps (i have sub-optimal hardware so thats expected)

LPeter1997•3mo ago

Wouldn't just having a powershell script to run it for you suffice? perftest.ps1 could just invoke dotnet run --configuration Release for you

it’s raining outsideOP•3mo ago

can i run that from vscode?

LPeter1997•3mo ago

Sure you can

it’s raining outsideOP•3mo ago

oh wow how then? lemme check if there are any extensions hold on also is powershell the same as cmd

LPeter1997•3mo ago

No need, you can just plop it into your launchsettings Well there's the old windows command line which is generally called CMD, but PowerShell is a .NET-based shell In this case it doesn't matter which one you use

it’s raining outsideOP•3mo ago

ooh do tell me more oh ok. i'll just use PS then wait how do you add to launchsettings?

LPeter1997•3mo ago

You might not even need it, let me try to do this manually in VSC

it’s raining outsideOP•3mo ago

because this is all i have

it’s raining outsideOP•3mo ago

👍 @LPeter1997 you good?

LPeter1997•3mo ago

I've just installed the new VSC extension, I'm still trying to figure out the new json schema they have

sibber•3mo ago

echo "dotnet run --configuration Release" > runrelease.cmd
./runrelease.cmd

echo "dotnet run --configuration Release" > runrelease.cmd
./runrelease.cmd

LPeter1997•3mo ago

Read back a little 😛

sibber•3mo ago

oh oops you want a launch profile?

it’s raining outsideOP•3mo ago

yeah (idk what that is)

sibber•3mo ago

so you can run from vscode i recommend just a script tho easier you dont even need a script just ⬆️

it’s raining outsideOP•3mo ago

yeah sure just hit the play button and see results yk

sibber•3mo ago

that wont add a play button iirc just allows you to run from the command bar thing

it’s raining outsideOP•3mo ago

how do you add that then

sibber•3mo ago

probably with an extention but youre putting too much effort into this'

LPeter1997•3mo ago

I mean it should be trivial to add a launchsetting that just specifies release but C# DevKit of course provides absolute dogshit documentation The schema doesn't even seem to include config as an option. You can do a pre-launch task to build a release version, won't use it to run that I think I got it So within the .vscode folder, you'd define a task to build a release. I did it like so (tasks.json):

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "dotnet: build release",
            "command": "dotnet",
            "type": "process",
            "args": [
                "build",
                "${workspaceFolder}/ConsoleApp1.csproj",
                "-c",
                "Release"
            ],
            "problemMatcher": "$msCompile"
        }
    ]
}

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "dotnet: build release",
            "command": "dotnet",
            "type": "process",
            "args": [
                "build",
                "${workspaceFolder}/ConsoleApp1.csproj",
                "-c",
                "Release"
            ],
            "problemMatcher": "$msCompile"
        }
    ]
}

And also within .vscode, defined a launchsetting to use the output DLL of the build (launch.json):

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Perftest Launch",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "dotnet: build release",
            "program": "${workspaceFolder}/bin/Release/net8.0/ConsoleApp1.dll",
            "args": [],
            "cwd": "${workspaceFolder}",
            "stopAtEntry": false
        },
    ]
}

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Perftest Launch",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "dotnet: build release",
            "program": "${workspaceFolder}/bin/Release/net8.0/ConsoleApp1.dll",
            "args": [],
            "cwd": "${workspaceFolder}",
            "stopAtEntry": false
        },
    ]
}

I think this should work, it worked for me

it’s raining outsideOP•3mo ago

it keeps fucking building (in the default way) i changed it to run in release

// tasks.json
{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "dotnet: run release",

            "args": [
                "run",
                "chess.csproj",
                "-c",
                "Release"
            ],
            "problemMatcher": "$msCompile"
        }
    ]
}

{
    "version": "2.0.0",
    "tasks": [
        {

                "run",
                "chess.csproj",
                "-c",
                "Release"
            ],
            "problemMatcher": "$msCompile"
        }
    ]
}

// launch.json
{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch C#",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "dotnet: run release",
            "program": "${workspaceFolder}/bin/Release/net8.0/chess.dll",
            "args": [],
            "cwd": "${workspaceFolder}",
            "stopAtEntry": false
        },
    ]
}

// launch.json
{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch C#",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "dotnet: run release",

            "stopAtEntry": false
        },
    ]
}

LPeter1997•3mo ago

That will run it as part of your pre-launch task instead

it’s raining outsideOP•3mo ago

whats a pre-launch task?

LPeter1997•3mo ago

A task it performs... drum roll ... before launching

it’s raining outsideOP•3mo ago

ohh and forgive me if i sound naggy or annoying, but how does that relate to the run button?

LPeter1997•3mo ago

Typically build Well to run, you generally build first Tools by default don't use dotnet run to run your thing They first build And then execute the built thing This is what dotnet run does as well in the background The main reason for this separation is so that a debug adapter and a debugger can hook into your running app showing you the pretty crashes and whatnot

it’s raining outsideOP•3mo ago

ohh ok i see ahh ok i see it now so how do i run it in release then? wait i can just clone the extension and edit the arguments wow programming is amazing

LPeter1997•3mo ago

The launch thing I gave you should launch the release built DLL (Make sure that the launch setting with that name is selected in the debug/run tab)

ah ok works fine now
