# Step 0 — Scaffold
|
||
|
||
## What this step delivers
|
||
|
||
A buildable Go binary (`latprobe`) that parses flags and URLs, prints usage
|
||
when invoked without arguments, and exits cleanly. No measurement logic yet —
|
||
the full implementation is wired in during Steps 1–4.
|
||
|
||
## Build
|
||
|
||
```sh
|
||
cd go
|
||
go build -o latprobe .
|
||
```
|
||
|
||
## Usage
|
||
|
||
```sh
|
||
# No arguments → prints usage and exits with code 1
|
||
./latprobe
|
||
|
||
# With a URL → scaffold message until Step 1 is implemented
|
||
./latprobe https://example.com
|
||
```
|
||
|
||
Expected output (scaffold stage):
|
||
|
||
```
|
||
latprobe — measure per-phase HTTP request latency
|
||
|
||
Usage:
|
||
latprobe [flags] <url> [url ...]
|
||
|
||
Flags:
|
||
-n, --count int Number of requests per URL (default 1)
|
||
--json Output results as JSON instead of text
|
||
-h, --help Show this help
|
||
|
||
Examples:
|
||
latprobe https://example.com
|
||
latprobe -n 5 https://example.com https://www.google.com
|
||
latprobe --json https://example.com | jq .
|
||
```
|
||
|
||
## Available flags (accepted by the parser, not yet functional)
|
||
|
||
| Flag | Short | Default | Description |
|
||
|------|-------|---------|-------------|
|
||
| `--count` | `-n` | `1` | Number of requests per URL |
|
||
| `--json` | — | false | Output as JSON instead of text |
|
||
| `--help` | `-h` | — | Show usage |
