Reference

Lua API

Learn what the generated Lua API reference is for.

Published by solever7 solever7
lua poplua api reference

The Lua API is the list of things Macchi lets scripts use. If macchi.reply sends a
message, ctx.user tells you who triggered the script, and a message builder creates
buttons, the API reference is where those names are written down.

You do not need this page to write your first script. Start with
Scripting if you want a gentler explanation. Come back here when
you are thinking, “I know what I want, but what is the exact name for it?”

Why This Page Exists

Macchi’s scripting API is generated from the host code through PopLua. That means the
reference can stay close to what the bot actually exposes instead of being a
hand-written guess.

The generated reference is more technical than the rest of the wiki. That is on purpose.
It is useful when you want to check a property, method, builder, or module name without
digging through source code.

How To Read It

Read it like a shelf, not like a novel. Search for the thing you are trying to do:
reply, build a message, inspect the current author, or work with script context. If a
name looks interesting, try it in a small script before building a whole flow around it.

For example, the scripting page shows:

macchi.reply("Hello " .. ctx.user.username)

The API reference is where you go when you want to know what else macchi or ctx.user
can do.

Current Member Mutation

ctx.member:changeNick("New nickname") is available only for the trusted member already
supplied by the trigger. It rechecks current Discord permissions and role hierarchy
immediately before the request, is durably audited without storing the nickname, and
never accepts a user ID from Lua. See the canonical Lua API
reference for the full contract.

ctx.member:dm("Message") sends one attributed DM to that same trusted member. It uses
the audited member.dm.send operation, recipient quotas, empty allowed mentions, and
guildless output ownership. Member invocation and eligible Server automation may use it.
DM content is not retained in operation audit.

Events Use The Same API

Scripts triggered by Events use the same general scripting surface.
The difference is what starts the script, not a totally separate language. A mention
script and a command script can both reply; they just run at different moments.

Delay Inside One Run

Use next.secs(seconds) for a short non-blocking pause:

next.secs(1)
macchi.reply("One second passed.")

The maximum delay is 10 seconds and one execution may request 5 delays. Waiting does not
spend the 2-second active-work budget, but it does spend the 30-second total lifetime
and stops promptly on cancellation. It does not schedule future work and does not
survive a restart.

For a short interactive flow, wait for the same member in the same channel:

local answer = next.message(10, "yes")
local reaction = next.reaction(10, "<:kitalua:1497600179472302180>")

Event waits are limited to 15 seconds and still consume the execution’s wall time. They
cannot listen across servers, channels, users, or executions.

Safe reaction changes

Macchi can add or remove only its own reaction on a message already provided by the
trusted context:

if ctx.message ~= nil then
    ctx.message:addReaction("<:kitalua:1497600179472302180>")
    -- ctx.message:removeOwnReaction("<:kitalua:1497600179472302180>")
end

Macchi checks the member, bot permissions, channel, message, and emoji again immediately
before Discord. The operation is durably audited without storing message content.
Arbitrary message IDs and removal of other users’ reactions are not available.

Trigger authority is assigned before event data is exposed. On automatic server events,
ctx.member may be the affected subject; its presence does not make that member an
authorizing actor. Server automation still requires its capabilities, current bot
permissions, scope checks, quotas, and audit.

A confirmed send returns an opaque owned output:

local sent = macchi.reply("Working...")
sent:edit(message.new():text("Done"))
-- sent:delete()

Only the same script and owner can mutate it. Edits rebuild attribution and allowed
mentions, while audit metadata never stores message content.

Trusted role add/remove and timeout set/clear are available only with explicit effective
capabilities, eligible Member or Server authority, current Discord permission and
hierarchy, target quotas, and durable content-free audit. Macchi-owned public threads
can be created, renamed, and archived through an opaque handle. Kick, ban, arbitrary
IDs, broad channel administration, and
third-party thread mutation remain unavailable.

Downloads And Editor Help

If you want files for autocomplete, local reference notes, or tooling, visit Lua API
Downloads. The most useful file for many Lua-aware editors
is poplua.d.lua, because it can help the editor understand Macchi-specific names.

If the generated artifact exists, it is rendered below. If it has not been generated
yet, Macchi shows a short placeholder instead.

PopLua Lua API

Schema poplua.lua-api v1, PopLua 1.0.0-rc.1.

Generated from C# PopLua binding declarations.

Contents

Modules

Module components

Convenience constructors for message component objects.

Component objects are inert until they are added to a message and sent. Macchi does not store durable Lua callbacks; interactive components route to named Lua entry functions in a fresh execution.

Capability: macchi.components

Functions

components.button(entry: string, label: string): Button

Creates an interactive button that can be added to a message.

Parameters:

  • entry — Lua function entry to invoke when clicked.
  • label — Visible button label.

Returns:

  • A Button object. The button is not sent until a message containing it is sent.
components.channelSelect(entry: string, placeholder: string | nil): EntitySelect

Creates a routed channel select.

Examples:

local select = components.channelSelect("picked", "Choose a channel")
components.linkButton(label: string, url: string): Button

Creates a link button that opens a URL instead of routing to Lua.

Parameters:

  • label — Visible button label.
  • url — Absolute http(s) URL.

Returns:

  • A link Button object.
components.mentionableSelect(entry: string, placeholder: string | nil): EntitySelect

Creates a routed user-or-role select.

Examples:

local select = components.mentionableSelect("picked", "Choose a target")
components.modal(title: string, entry: string, label: string | nil): Modal

Creates a durable modal opened by a button in an owned message.

Examples:

local form = components.modal("Feedback", "submitFeedback")
form:paragraph("message", "Message")
components.option(label: string, value: string, description: string | nil): SelectOption

Creates an option for a select menu.

components.roleSelect(entry: string, placeholder: string | nil): EntitySelect

Creates a routed role select.

Examples:

local select = components.roleSelect("picked", "Choose a role")
components.select(entry: string, placeholder: string | nil): Select

Creates a select menu that can be added to a message.

Parameters:

  • entry — Lua function entry to invoke when a value is selected.
  • placeholder — Placeholder shown before selection.

Returns:

  • A Select object. The menu is not sent until a message containing it is sent.
components.userSelect(entry: string, placeholder: string | nil): EntitySelect

Creates a routed user select.

Examples:

local select = components.userSelect("picked", "Choose a user")
