Aliasing API

So you want to write aliases for your commonly used commands - cool! This cheatsheet details some of the nitty-gritty syntactical shenanigans that you can use to make your aliases very powerful.

When placed inline in an alias, any syntax in the syntax table will have the listed effect. For a list of built-in cvars, see the Cvar Table.

For a list of user-created aliases, plus help aliasing, join the Avrae Discord!

Draconic

The language used in Avrae aliases is a custom modified version of Python, called Draconic. In most cases, Draconic uses the same syntax and base types as Python - any exceptions will be documented here!

Note

It is highly recommended to be familiar with the Python language before diving into Draconic, as the two use the same syntax and types.

As Draconic is meant to both be an operational and templating language, there are multiple ways to use Draconic inside your alias.

Syntax

This section details the special syntax used in the Draconic language. Note that these syntaxes are only evaluated in an alias, the test command, or the tembed command.

Rolls

Syntax: {diceexpr}

Description: Rolls the expression inside the curly braces and is replaced by the result. If an error occurs, is replaced by 0. Variables are allowed inside the expression.

Examples

>>> !test Rolling 1d20: {1d20}
Rolling 1d20: 7

>>> !test Strength check: {1d20 + strengthMod}
Strength check: 21

Values

Syntax: <var>

Description: Replaced by the value of the variable, implicitly cast to str. The variable can be a user variable, character variable, or a local variable set in a Draconic script.

Examples

>>> !test My strength modifier is: <strengthMod>
My strength modifier is: 2

Draconic Expressions

Syntax: {{code}}

Description: Runs the Draconic code inside the braces and is replaced by the value the code evaluates to. If the code evaluates to None, is removed from the output, otherwise it is cast to str.

See below for a list of builtin Draconic functions.

Examples

>>> !test 1 more than my strength score is {{strength + 1}}!
1 more than my strength score is 15!

>>> !test My roll was {{"greater than" if roll("1d20") > 10 else "less than"}} 10!
My roll was less than 10!

Draconic Blocks

Syntax

<drac2>
code
</drac2>

Description: Runs the multi-line Draconic code between the delimiters. If a non-None value is returned (via the return keyword), is replaced by the returned value, cast to str.

Examples

>>> !test <drac2>
... out = []
... for i in range(5):
...   out.append(i * 2)
...   if i == 2:
...     break
... return out
... </drac2>
[0, 2, 4]

>>> !test <drac2>
... out = []
... for stat in ['strength', 'dexterity', 'constitution']:
...   out.append(get(stat))
... </drac2>
... My STR, DEX, and CON scores are {{out}}!
My STR, DEX, and CON scores are [12, 18, 14]!

Argument Parsing

Often times when writing aliases, you will need to access user input. These special strings will be replaced with user arguments (if applicable)!

Non-Code, Space-Aware

Syntax: %1%, %2%, …, %N%

Description: Replaced with the Nth argument passed to the alias. If the argument contains spaces, the replacement will contain quotes around the argument.

Non-Code, Preserving All

Syntax: %*%

Description: Replaced with the unmodified string following the alias.

In Code, Quote-Escaping

Syntax: &1&, &2&, etc.

Description: Replaced with the Nth argument passed to the alias. If the argument contains spaces, the replacement will not contain quotes around the argument. Additionally, any quotes in the argument will be backslash-escaped.

In Code, Quote-Escaping All

Syntax: &*&

Description: Replaced with the string following the alias. Any quotes will be backslash-escaped.

In Code, List Literal

Syntax: &ARGS&

Description: Replaced with a list representation of all arguments - usually you’ll want to put this in Draconic code.

Examples

>>> !alias asdf echo %2% %1%
>>> !asdf first "second arg"
"second arg" first

>>> !alias asdf echo %*% first
>>> !asdf second "third word"
second "third word" first

>>> !alias asdf echo &1& was the first arg
>>> !asdf "hello world"
hello world was the first arg

>>> !alias asdf echo &*& words
>>> !asdf second "third word"
second \"third word\" words

>>> !alias asdf echo &ARGS&
>>> !asdf first "second arg"
['first', 'second arg']

Cvar Table

Function Reference

Warning

It may be possible to corrupt your character data by incorrectly calling functions. Script at your own risk.

Python Builtins

abs(x)

Return type: int

len(s)

Return the length (the number of items) of an object. The argument may be a sequence (such as a string, bytes, tuple, list, or range) or a collection (such as a dictionary, set, or frozen set).

Returns: The length of the argument.
Return type: int

max(iterable, *[, key, default])

max(arg1, arg2, *args[, key])

Return the largest item in an iterable or the largest of two or more arguments.

If one positional argument is provided, it should be an iterable. The largest item in the iterable is returned. If two or more positional arguments are provided, the largest of the positional arguments is returned.

There are two optional keyword-only arguments. The key argument specifies a one-argument ordering function like that used for list.sort(). The default argument specifies an object to return if the provided iterable is empty. If the iterable is empty and default is not provided, a ValueError is raised.

If multiple items are maximal, the function returns the first one encountered.

min(iterable, *[, key, default])

min(arg1, arg2, *args[, key])

Return the smallest item in an iterable or the smallest of two or more arguments.

If one positional argument is provided, it should be an iterable. The smallest item in the iterable is returned. If two or more positional arguments are provided, the smallest of the positional arguments is returned.

There are two optional keyword-only arguments. The key argument specifies a one-argument ordering function like that used for list.sort(). The default argument specifies an object to return if the provided iterable is empty. If the iterable is empty and default is not provided, a ValueError is raised.

If multiple items are minimal, the function returns the first one encountered.

range(stop)

range(start, stop[, step])

Returns a list of numbers in the specified range.

If the step argument is omitted, it defaults to 1. If the start argument is omitted, it defaults to 0. If step is zero, ValueError is raised.

For a positive step, the contents of a range r are determined by the formula r[i] = start + step*i where i >= 0 and r[i] < stop.

For a negative step, the contents of the range are still determined by the formula r[i] = start + step*i, but the constraints are i >= 0 and r[i] > stop.

A range object will be empty if r[0] does not meet the value constraint. Ranges do support negative indices, but these are interpreted as indexing from the end of the sequence determined by the positive indices.

Parameters

start (int) – The start of the range (inclusive).
stop (int) – The end of the range (exclusive).
step (int) – The step value.

Returns

The range of numbers.

Return type

Converts x to a string.

Parameters: x (Any) – The value to convert.
Returns: The string.
Return type: str

sum(iterable[, start]): Sums start and the items of an iterable from left to right and returns the total. start defaults to 0. The iterable’s items are normally numbers, and the start value is not allowed to be a string.

Return the time in seconds since the UNIX epoch (Jan 1, 1970, midnight UTC) as a floating point number. See time.time().

Returns: The epoch time.
Return type: float

Draconic Functions

argparse(args, parse_ephem=True)

Given an argument string or list, returns the parsed arguments using the argument nondeterministic finite automaton.

If parse_ephem is False, arguments like -d1 are saved literally rather than as an ephemeral argument.

Note

Arguments must begin with a letter and not end with a number (e.g. d, e12s, a!!). Values immediately following a flag argument (i.e. one that starts with -) will not be parsed as arguments unless they are also a flag argument.

There are three exceptions to this rule: -i, -h, and -v, none of which take additional values.

Parameters

args – A list or string of arguments.
parse_ephem (bool) – Whether to treat args like -d1 as ephemeral arguments or literal ones.

Returns

The parsed arguments

Return type

ParsedArguments()

>>> args = argparse("adv -rr 2 -b 1d4[bless]")
>>> args.adv()
1
>>> args.last('rr')

Returns

The value of the uvar, or the default value if it does not exist.

Return type

str or None

randint(stop)

randint(start, stop[, step])

Returns a random integer in the range [start..stop).

If the step argument is omitted, it defaults to 1. If the start argument is omitted, it defaults to 0. If step is zero, ValueError is raised.

For a positive step, the contents of a range r are determined by the formula r[i] = start + step*i where i >= 0 and r[i] < stop.

For a negative step, the contents of the range are still determined by the formula r[i] = start + step*i, but the constraints are i >= 0 and r[i] > stop.

Sets a user variable if there is not already an existing name.

Parameters

name (str) – The name of the variable to set.
value (str) – The value to set it to.

signature(data=0)

Returns a unique signature encoding the time the alias was invoked, the channel it was invoked in, the invoker, the id of the workshop collection the alias originates from (if applicable), and whether the caller was a personal/server alias/snippet.

This signature is signed with a secret that guarantees that valid signatures cannot be spoofed; use this when it is necessary to audit the invocations of an alias (e.g. to ensure that a server version of the alias is being used over a personal version).

Use verify_signature() in a separate alias to verify the integrity of a generated signature and unpack the encoded data.

Parameters: data (int) – Some user-supplied data to encode in the signature. This must be an unsigned integer that fits within 5 bits (i.e. a value [0..31]). Default 0.
Return type: str

verify_signature(data)

Verifies that a given signature is valid. The signature should have been generated by signature().

If the signature is not valid, raises a ValueError. Otherwise, returns a dict with the following keys representing the context the given signature was generated in:

{
    "message_id": int,
    "channel_id": int,
    "author_id": int,
    "timestamp": float,
    "workshop_collection_id": str?,  # None if the caller was not a workshop object
    "scope": str,  # one of UNKNOWN, PERSONAL_ALIAS, SERVER_ALIAS, PERSONAL_SNIPPET, SERVER_SNIPPET, COMMAND_TEST
    "user_data": int,
    "guild_id": int?,  # may be None
    "guild": AliasGuild?,  # may be None
    "channel": AliasChannel?,  # may be None
    "author": AliasAuthor?,  # may be None
}

Parameters: data (str) – The signature to verify.
Return type: dict

If you are building your own application and want to verify these signatures yourself, we provide an API endpoint you can use to verify signatures!

Below is an example of Python code to verify a signature using the httpx (requests-like) library:

signature = "Dc3SEuDEMKIJZ0qbasAAAQKZ2xjlQgAAAAAAAAAAAAAAAAAABQ==.B5RLdufsD9utKaDou+94LEfOgpA="
async with httpx.AsyncClient() as client:
    r = await client.post(
        "https://api.avrae.io/bot/signature/verify",
        json={"signature": signature}
    )
print(r.json(indent=2))

The endpoint’s response model is the same as verify_signature() sans the guild, channel, and author keys (IDs are still present).

typeof(inst)

Returns the name of the type of an object.

Parameters: inst – The object to find the type of.
Returns: The type of the object.
Return type: str

using(self, **imports)

Imports Draconic global variables as modules in the current namespace. See Using Imports for details.

Usually this should be the first statement in a code block if imports are used.

Warning

Only import modules from trusted sources! The entire contents of an imported module is executed once upon import, and can do bad things like delete all of your variables.

>>> using(
...     hello="50943a96-381b-427e-adb9-eea8ebf61f27"
... )
>>> hello.hello()
"Hello world!"

uvar_exists(name)

Returns whether a uvar exists.

Return type: bool

vroll(rollStr, multiply=1, add=0)

Rolls dice and returns a detailed roll result.

Parameters

dice (str) – The dice to roll.
multiply (int) – How many times to multiply each set of dice by.
add (int) – How many dice to add to each set of dice.

Returns

The result of the roll.

Return type

SimpleRollResult

parse_coins(args: str) → dict

Parses a coin string into a representation of each currency. If the user input is a decimal number, assumes gold pieces. Otherwise, allows the user to specify currencies in the form ‘+1gp -2sp 3cp’

Returns: A dict of the coin changes, e.g. {"pp":0, "gp":1, "ep":0, "sp":-2, "cp":3, "total": 0.83}
Return type: dict

Variable Scopes

In addition to Python’s normal variable scoping rules, Avrae introduces 4 new scopes in the form of character variables, user variables, server variables, and global variables. The intended purpose and binding rules of each are detailed below.

Variable Type	Read	Write	Binding	Scope	Who
Cvar	Yes	Yes	Implicit	Character	User
Uvar	Yes	Yes	Implicit	User	User
Svar	Yes	No	Explicit	Server	Anyone on server
Gvar	Yes	No	Explicit	Everywhere	Anyone
Init Metadata	Yes	Yes	Explicit	Initiative	Anyone in channel

Character Variables

aka cvars

Character variables are variables bound to a character. These are usually used to set character-specific defaults or options for aliases and snippets (e.g. a character’s familiar type/name). When running an alias or snippet, cvars are implicitly bound as local variables in the runtime at the runtime’s instantiation.

Cvars can be written or deleted in Draconic using AliasCharacter.set_cvar() and AliasCharacter.delete_cvar(), respectively.

All characters contain some built-in character variables (see Cvar Table). These cannot be overwritten.

User Variables

aka uvars

User variables are bound per Discord user, and will go with you regardless of what server or character you are on. These variables are usually used for user-specific options (e.g. a user’s timezone, favorite color, etc.). When running an alias or snippet, uvars are implicitly bound as local variables in the runtime at the runtime’s instantiation. If a cvar and uvar have the same name, the cvar takes priority.

Uvars can be written or deleted in Draconic using set_uvar() or delete_uvar(), respectively.

Server Variables

aka svars

Server variables are named variables bound per Discord server, and can only be accessed in the Discord server they are bound in. These variables are usually used for server-specific options for server aliases (e.g. stat rolling methods, server calendar, etc.). Unlike cvars and uvars, svars must be explicitly retrieved in an alias by calling get_svar(). Svars can be listed and read by anyone on the server, so be careful what data you store!

Svars can only be written or deleted using !svar <name> <value> and !svar delete <name>, respectively. These commands can only be issued by a member who has Administrator Discord permissions or a Discord role named “Server Aliaser” or “Dragonspeaker”.

Global Variables

aka gvars

Global variables are uniquely named variables that are accessible by anyone, anywhere in Avrae. These variables are usually used for storing large amounts of read-only data (e.g. an alias’ help message, a JSON file containing cards, etc.). These variables are automatically assigned a unique name on creation (in the form of a 36 character UUID), and must be explicitly retrieved in an alias by calling get_gvar(). Gvars can be read by anyone, so be careful what data you store!

Gvars can only be created using !gvar create <value>, and by default can only be edited by its creator. See !help gvar for more information.

Honorable Mention: Initiative Metadata

Initiative metadata is a form of key-value pair storage attached to an ongoing initiative in a given channel. This storage is usually used for storing a medium-sized amount of programmatic information about an ongoing initiative (e.g. an alias’ metadata on each combatant).

Metadata can be created, retrieved, and deleted using the SimpleCombat.set_metadata(), SimpleCombat.get_metadata(), and SimpleCombat.delete_metadata() methods, respectively.

Using Imports

Imports are a way for alias authors to share common code across multiple aliases, provide common libraries of code for other authors to write code compatible with your alias, and more!

If you already have the address of a module to import, use using() at the top of your code block in order to import the module into your namespace. For example:

!alias hello-world echo <drac2>
using(
    hello="50943a96-381b-427e-adb9-eea8ebf61f27"
)
return hello.hello()
</drac2>

Use !gvar 50943a96-381b-427e-adb9-eea8ebf61f27 to take a peek at the hello module!

You can also import multiple modules in the same expression:

!alias hello-world echo <drac2>
using(
    hello="50943a96-381b-427e-adb9-eea8ebf61f27",
    hello_utils="0bbddb9f-c86f-4af8-9e04-1964425b1554"
)
return f"{hello.hello('you')}\n{hello_utils.hello_to_my_character()}"
</drac2>

The hello_utils module (!gvar 0bbddb9f-c86f-4af8-9e04-1964425b1554) also demonstrates how modules can import other modules!

Each imported module is bound to a namespace that contains each of the names (constants, functions, etc) defined in the module. For example, the hello module (50943a96-381b-427e-adb9-eea8ebf61f27) defines the HELLO_WORLD constant and hello() function, so a consumer could access these with hello.HELLO_WORLD and hello.hello(), respectively.

Warning

Only import modules from trusted sources! The entire contents of an imported module is executed once upon import, and can do bad things like delete all of your variables.

All gvar modules are open-source by default, so it is encouraged to view the imported module using !gvar.

Note

Modules do not have access to the argument parsing special syntax (i.e. &ARGS&, %1%, etc), and the variables listed in the Cvar Table are not implicitly bound in a module’s execution.

Writing Modules

Modules are easy to publish and update! Simply create a gvar that contains valid Draconic code (without wrapping it in any delimiters such as <drac2>).

We encourage modules to follow the following format to make them easy to read:

# recommended_module_name
# This is a short description about what the module does.
#
# SOME_CONSTANT: some documentation about what this constant is
# some_function(show, the, args): some short documentation about what this function does
#     and how to call it
#     wow, this is long! use indentation if you need multiple lines
#     but otherwise longer documentation should go in the function's """docstring"""

SOME_CONSTANT = 3.141592

def some_function(show, the, args):
    """Here is where the longer documentation about the function can go."""
    pass

Use !gvar 50943a96-381b-427e-adb9-eea8ebf61f27 and !gvar 0bbddb9f-c86f-4af8-9e04-1964425b1554 to view the hello and hello_utils example modules used above for an example!

Note

Because all gvars are public to anyone who knows the address, modules are open-source by default.

Catching Exceptions

Draconic supports a modified version of Python’s exception handling (“try-except”) syntax, the most significant difference being that exceptions must be caught explicitly by passing the exact name of the exception type to the except clause as a string or tuple of strings. A bare except may also be used to catch any exception in the try block.

For example, to cast an arbitrary string to an integer and catch errors raised by int():

!test <drac2>
some_string = "123"
try:
    return int(some_string)
except ("ValueError", "TypeError"):
    return "I couldn't parse an int!"
</drac2>

Note

Unlike Python, only the exact exception type given by a string will be matched, without subclass checking.

Draconic try statements also support else and finally blocks, similar to Python.

Initiative Models
