awkbuilder

Local web UI for visually constructing, tracing, and verifying awk programs.

Setup

Requires Go 1.26+.

go install github.com/99-not-out/awkbuilder@latest

Or from a clone:

git clone https://github.com/99-not-out/awkbuilder.git
cd awkbuilder
go build ./...

Run

awkbuilder [flags] [files-or-globs...]

Flags:

• -port N — listen on port N (default 0 picks a free port)
• -no-open — don't auto-open the browser
• -limit N — cap records read per input file (default 0 = no cap)

Example with the bundled samples:

awkbuilder samples/access.log samples/users.csv

The server prints the URL it's bound to, and (unless -no-open) opens it in your default browser.
