• curprev 23:2423:24, 8 October 2024‎ Plushkava talk contribs‎ m 12,478 bytes +523‎ Show the example ruleset at the end in the "list ruleset" style as well as a series of incremental commands
• curprev 23:1023:10, 8 October 2024‎ Plushkava talk contribs‎ m 11,955 bytes +3‎ Replace a stray instance of "foo"
• curprev 23:0823:08, 8 October 2024‎ Plushkava talk contribs‎ m 11,952 bytes +193‎ Describe the conventions for examples of nftables grammar

• curprev 22:5622:56, 8 October 2024‎ Plushkava talk contribs‎ 11,747 bytes +1,309‎ Add a "Syntactic conventions" section in an attempt to bring the standard closer to that of formal documentation; have it subsume the aside regarding matters of shell quoting that was previously in the "Adding base chains" section
• curprev 22:2222:22, 8 October 2024‎ Plushkava talk contribs‎ m 10,438 bytes +79‎ Introduce nft grammar with a consistent style of English; make the flush chain example an example of grammar rather than an example of a shell command (just like how the section on deleting begins)
• curprev 21:5721:57, 8 October 2024‎ Plushkava talk contribs‎ m 10,359 bytes +1‎ Employ a chain name of eth0_filter rather than dev0filter in the ingress hook example (it seems a little clearer)
• curprev 21:4921:49, 8 October 2024‎ Plushkava talk contribs‎ m 10,358 bytes +61‎ Consistently use table/chain names that reflect iptables norms, just as the final <source> block already does
• curprev 21:4021:40, 8 October 2024‎ Plushkava talk contribs‎ m 10,297 bytes −136‎ Use # to denote a shell prompt (as is typical for a root session in virtually any sh implementation, including the ever-popular bash); only include a faux-prompt in examples intended to show shell commands rather than those that act as synopses of nft(8) grammar; don't apply bash syntax highlighting (it hinders more than it helps); employ shell quoting consistently in all examples
• curprev 21:2921:29, 8 October 2024‎ Plushkava talk contribs‎ m 10,433 bytes +10‎ Clean up the synopsis for adding base chains; have it cover "device"
