i use vscode, and i already have the build on save option enabled. does this article do anything different?

Improving Your Zig Language Server Experience

...by adding just a few lines to your build.zig

#

This creates another step that ends up using -fno-emit-bin. That makes the build much quicker since there’s no need to call llvm

prime oracle Jul 27, 2024, 1:25 AM

#

ok, so it is slighty better

#

i dont have a config for zls. do i just create one in the same location as the exe?

south ermine Jul 27, 2024, 1:34 AM

#

Iirc you run zls --show-config-location

prime oracle Jul 27, 2024, 1:34 AM

#

i ran it, and the config just doesnt exist

south ermine Jul 27, 2024, 1:35 AM

#

VSCode might have some interface for it though. Probably use that if it’s a thing

#

If none of that’s a thing, try zls env. That should show where zls will look for the config

prime oracle Jul 27, 2024, 1:37 AM

#

there is this

#

what is zls env?

south ermine Jul 27, 2024, 1:38 AM

#

Docs say zls env will show you where zls looks

#

Yeah, so use the VSCode interface since it’s there

prime oracle Jul 27, 2024, 1:39 AM

#

south ermine Docs say `zls env` will show you where zls looks

zls env isnt a valid command

south ermine Jul 27, 2024, 1:39 AM

#

Oh it’s since 0.14.0-dev.50+3354fdcb, sorry

prime oracle Jul 27, 2024, 1:40 AM

#

oh ok

#

ok well build on save just isnt doing anything now

south ermine Jul 27, 2024, 1:49 AM

#

Is the build on save step a valid step?

#

And check that it’s enabled

prime oracle Jul 27, 2024, 1:50 AM

#

prime oracle Jul 27, 2024, 1:50 AM

#

south ermine Is the build on save step a valid step?

typing in zig build -h shows the step

south ermine Jul 27, 2024, 1:52 AM

#

Try running the step yourself

prime oracle Jul 27, 2024, 1:53 AM

#

it works when i run it myself

#

Build on save not working

#

const std = @import("std");

pub fn build(b: *std.Build) void {
    const target = b.standardTargetOptions(.{});
    const optimize = b.standardOptimizeOption(.{});

    const exe = b.addExecutable(.{
        .name = "hello_world",
        .root_source_file = b.path("src/main.zig"),
        .target = target,
        .optimize = optimize,
    });

    b.installArtifact(exe);

    const run_cmd = b.addRunArtifact(exe);

    run_cmd.step.dependOn(b.getInstallStep());

    if (b.args) |args| {
        run_cmd.addArgs(args);
    }

    const run_step = b.step("run", "Run the app");
    run_step.dependOn(&run_cmd.step);

    const exe_unit_tests = b.addTest(.{
        .root_source_file = b.path("src/main.zig"),
        .target = target,
        .optimize = optimize,
    });

    const run_exe_unit_tests = b.addRunArtifact(exe_unit_tests);

    const test_step = b.step("test", "Run unit tests");
    test_step.dependOn(&run_exe_unit_tests.step);

    // check step
    const exe_check = b.addExecutable(.{
        .name = "hello_world",
        .root_source_file = b.path("src/main.zig"),
        .target = target,
        .optimize = optimize,
    });

    const check = b.step("check", "Check if program compiles without invoking llvm");
    check.dependOn(&exe_check.step);
}

this is the build script, in case that helps

what does the Zig Language Sever output panel say

prime oracle Jul 27, 2024, 2:26 AM

#

kindred sinew Jul 27, 2024, 2:26 AM

#

also why did u make the build on save step "install" instead of "check"

prime oracle Jul 27, 2024, 2:27 AM

#

i didnt, i was just showing them it exists

#

i changed it to check

#

install is just the default

#

restarting the server does not do anything either

#

tf is this?

kindred sinew Jul 27, 2024, 2:48 AM

#

that usually means its lagging and shouldnt last long

#

is it a big file

prime oracle Jul 27, 2024, 2:58 AM

#

const std = @import("std");

fn m(x: anytype) void {
    std.debug.print("{d}", .{x.len});
}

pub fn main() !void {
    m(100);
}

not at all

#

i removed the check function

prime oracle Jul 27, 2024, 3:32 AM

#

fuck it, clean reinstall of zls

prime oracle Jul 27, 2024, 10:15 PM

#

i’m still struggling with this, if anyone has any tips, please @ me

forest hazel Jul 28, 2024, 7:20 AM

#

take a look at this zls hack I did, give it a try: https://github.com/Syndica/sig/blob/main/build.zig

GitHub

sig/build.zig at main · Syndica/sig

a Solana validator client implementation written in Zig - Syndica/sig

#

the makeZlsNotInstallAnythingDuringBuildOnSave thing

#

this is how we avoid emitting the binary proper with little editing of the core build.zig logic

prime oracle Jul 28, 2024, 7:21 AM

#

build on save doesnt even work for me

#

it just doesnt build on save

forest hazel Jul 28, 2024, 7:21 AM

#

also see the zls json file

forest hazel Jul 28, 2024, 7:21 AM

#

prime oracle it just doesnt build on save

interesting

#

what's the log say

prime oracle Jul 28, 2024, 7:22 AM

#

i am using vscode, this is what i get

it seems to recognize the change

forest hazel Jul 28, 2024, 7:23 AM

#

appears to be enabling build on save

#

indeed

prime oracle Jul 28, 2024, 7:24 AM

#

is there any other log i can check? this is just the vscode output terminal

forest hazel Jul 28, 2024, 7:24 AM

#

does it output any log when you save the file and build

#

or nada

prime oracle Jul 28, 2024, 7:25 AM

#

nope, but ive never seen it do that when it was working before

forest hazel Jul 28, 2024, 7:25 AM

#

prime oracle there is this

also, this should be check, is it?

prime oracle Jul 28, 2024, 7:25 AM

#

yup, that was changed. i was just showing them the setting exists

forest hazel Jul 28, 2024, 7:27 AM

#

prime oracle ```js const std = @import("std"); fn m(x: anytype) void { std.debug.print("...

what's the current code you are testing on, still this?

prime oracle Jul 28, 2024, 7:27 AM

#

const std = @import("std");

fn m(x: anytype) void {
    std.debug.print("{d}", .{x.len});
}

pub fn main() !void {
    const x = @as(u32, -1);
    _ = x;
    m(100);
}

pretty much the same

#

the problem is, idk if it is a vscode issue or a zls issue

forest hazel Jul 28, 2024, 7:27 AM

#

try something inline just to be sure, ie _ = x.len;

#

probably won't change anything

#

but best to rule out the possibility

prime oracle Jul 28, 2024, 7:28 AM

#

nothing

forest hazel Jul 28, 2024, 7:29 AM

#

there might well be a vscode setting you need to enable

#

because afaict this should be working

#

quick check: what's your OS

prime oracle Jul 28, 2024, 7:29 AM

#

windows

#

windows 11

forest hazel Jul 28, 2024, 7:30 AM

#

do you have any antivirus, and if so, have you given behaviour exceptions to both zig and zls

prime oracle Jul 28, 2024, 7:30 AM

#

i do, but its one my school forces me to download. i dont think it does anything

forest hazel Jul 28, 2024, 7:31 AM

#

antiviruses are a royal pain for "unsigned executables"

#

what's its name?

prime oracle Jul 28, 2024, 7:31 AM

#

Sentinel One

#

i know nothing about it, i was required to download it because my schooll network requires it or some bs like that

SentinelOne - Path Exclusion

Path Exclusion is a feature in SentinelOne that allows an administrator to suppress false positive events originating from specific files and processes. It also enables an administrator to exclude a path or file from monitoring where there are any interoperability issues. The exclusion also applies to processes whose route process is in the excl...

prime oracle Jul 28, 2024, 7:32 AM

#

all it does is give me warnings when i run cmake

forest hazel Jul 28, 2024, 7:32 AM

#

I would add zig and zls to the exclusion paths to be sure

#

and mayhaps your entire dev directory

prime oracle Jul 28, 2024, 7:32 AM

#

clangd works fine (another lsp) but ill try that

forest hazel Jul 28, 2024, 7:33 AM

#

clangd is probably recognized/signed software

prime oracle Jul 28, 2024, 7:33 AM

#

hmmmmm

forest hazel Jul 28, 2024, 7:33 AM

#

lol

prime oracle Jul 28, 2024, 7:34 AM

#

forest hazel https://www.cybervigilance.uk/post/sentinelone-path-exclusion

i cant even find the setting to do this

prime oracle Jul 28, 2024, 7:34 AM

#

prime oracle all it does is give me warnings when i run cmake

this is all that shows

#

even when running as an admin

forest hazel Jul 28, 2024, 7:34 AM

#

just to check, I know the log said it is, but is zls --version 0.13?

prime oracle Jul 28, 2024, 7:35 AM

#

yup, it is 0.13.0

forest hazel Jul 28, 2024, 7:36 AM

#

quite strange a situation

#

I'm assuming you've restarted the extension host plenty

prime oracle Jul 28, 2024, 7:36 AM

#

lol yup

#

i did reinstall zls through the extension multiple times

forest hazel Jul 28, 2024, 7:37 AM

#

what does the install dir for the vscode zls look like

prime oracle Jul 28, 2024, 7:37 AM

#

    Directory: C:\Users\radei\AppData\Roaming\Code\User\globalStorage\ziglang.vscode-zig\zls_install


Mode                 LastWriteTime         Length Name

-a----         7/26/2024   8:32 PM        3366912 zls.exe

just the exe

#

not even a config, which is weird

#

im relying on vscode's config

forest hazel Jul 28, 2024, 7:38 AM

#

wait a sec, is that the same as the one in your path?

#

run that zls.exe

#

with --version

prime oracle Jul 28, 2024, 7:38 AM

#

zls is not set on my path, vs code sets the path of zls

forest hazel Jul 28, 2024, 7:38 AM

#

I see

prime oracle Jul 28, 2024, 7:39 AM

#

wait lemme check my path, maybe i did put it on the path and forgot

#

yeah its not there, its just set by vscode

forest hazel Jul 28, 2024, 7:41 AM

#

honestly haven't the foggiest clue what could be going wrong

#

my last hunch is that zls 0.13.0 is just broken on windows

drowsy sun Jul 28, 2024, 7:41 AM

#

doesnt vscode have a place to put flags/options for zls?

forest hazel Jul 28, 2024, 7:41 AM

#

if you wanna try confirming that, try downgrading to 0.12.0

#

and see if that suddenly makes it work

prime oracle Jul 28, 2024, 7:41 AM

#

drowsy sun doesnt vscode have a place to put flags/options for zls?

yeah vscode has a json config

forest hazel Jul 28, 2024, 7:42 AM

#

at least then we'd know if it's a broken zls thing

#

(as in for both zig and zls)

prime oracle Jul 28, 2024, 7:42 AM

#

ill try that

forest hazel Jul 28, 2024, 7:43 AM

#

very annoying, I know

prime oracle Jul 28, 2024, 7:46 AM

#

still not working

forest hazel Jul 28, 2024, 7:46 AM

#

well damn

prime oracle Jul 28, 2024, 7:46 AM

#

i changed the path of zls in the settings to the 0.12 version

forest hazel Jul 28, 2024, 7:46 AM

#

this is smelling like a vscode thing?

prime oracle Jul 28, 2024, 7:46 AM

#

i think so

#

i have been looking for an excuse to use nvim 👀

#

it used to work though

forest hazel Jul 28, 2024, 7:47 AM

#

I'll be that guy and say try helix :p

prime oracle Jul 28, 2024, 7:48 AM

#

i could try that out too, im guessing it wouldnt need to do as much configuring

#

but arent the bindings different from vim?

forest hazel Jul 28, 2024, 7:49 AM

#

yeah, comes a bit more out of the box ready - and yeah, it uses a sort of opposite paradigm. vim is verb+noun, whilst helix is noun+verb

#

so in vim you decide what you're going to do, and then you select what you're doing it to

#

whereas in helix, you select something, and then you apply an action

#

for me the latter was more intuitive, but you'll have to be the judge

forest hazel Jul 28, 2024, 7:50 AM

#

prime oracle it used to work though

but also, yeah idk, common experience with vscode lol

prime oracle Jul 28, 2024, 7:51 AM

#

thanks for the helo

#

help

forest hazel Jul 28, 2024, 7:51 AM

#

I mean

#

wild thought, it could suddenly resume working next time you restart your computer

prime oracle Jul 28, 2024, 7:51 AM

#

ive tried restarting my computer

#

nothing

forest hazel Jul 28, 2024, 7:51 AM

#

lol dang

#

fully broken

prime oracle Jul 28, 2024, 7:52 AM

#

yup

#

thanks for sticking with me through this

forest hazel Jul 28, 2024, 7:52 AM

#

yeah no problem, sorry to not be of more help
