I’m using helix as my main editor writing zig. Most of time experiences ars nice like highliting, lsp, code navigation …, except for debugging. When launching debug whith binary, I got a Failed to start debug client: server closed the stream message.
Here is my environment:
zig:0.15.2zls:0.15.0lldb(dap):21.1.4helix:25.07.1 (a05c151b)
Files:
// src/main.zig
const std = @import("std");
pub fn main() !void {
// Prints to stderr, ignoring potential errors.
const str = "codebase";
std.debug.print("All your {s} are belong to us.\n", .{str});
}
test "simple test" {
const gpa = std.testing.allocator;
var list: std.ArrayList(i32) = .empty;
defer list.deinit(gpa); // Try commenting this out and see if zig detects the memory leak!
try list.append(gpa, 42);
try std.testing.expectEqual(@as(i32, 42), list.pop());
}
test "fuzz example" {
const Context = struct {
fn testOne(context: @This(), input: []const u8) anyerror!void {
_ = context;
// Try passing `--fuzz` to `zig build test` and see if it manages to fail this test case!
try std.testing.expect(!std.mem.eql(u8, "canyoufindme", input));
}
};
try std.testing.fuzz(Context{}, Context.testOne, .{});
}
// build.zig
const std = @import("std");
pub fn build(b: *std.Build) void {
const target = b.standardTargetOptions(.{});
const optimize = b.standardOptimizeOption(.{});
const exe = b.addExecutable(.{
.name = "demo",
.root_module = b.createModule(.{
.root_source_file = b.path("src/main.zig"),
.target = target,
.optimize = optimize,
}),
.use_llvm = true,
});
b.installArtifact(exe);
const run_step = b.step("run", "Run the app");
const run_cmd = b.addRunArtifact(exe);
run_step.dependOn(&run_cmd.step);
run_cmd.step.dependOn(b.getInstallStep());
if (b.args) |args| {
run_cmd.addArgs(args);
}
const exe_tests = b.addTest(.{
.root_module = exe.root_module,
.use_llvm = true,
});
b.installArtifact(exe_tests);
const run_exe_tests = b.addRunArtifact(exe_tests);
const test_step = b.step("test", "Run tests");
test_step.dependOn(&run_exe_tests.step);
}
But I can debug binary with only lldb successfully.
