Project description
Allay
A parser to convert a descriptive text format into minecraft text components
Getting Started
First, install the package with pip install allay
.
Next, create a python script and import allay.
Usage is extremely simple:
import allay
parser = allay.Parser()
text_component = parser.parse(string)
Format
Allay uses a markdown-inspired format. To start, we'll define our types.
string
-"string"
integer
-49
url/link
-"https://example.com"
boolean
-true/false
hex code
-#ff0000
color
- Any built in color such asred
,blue
,black
, etc.scope block
-<text>
. Scope blocks are just like normal text, except any modifier that involves clicking or hovering cannot be used and will raise an error. They are only used inhover_text
, and can use normal modifiers likebold
,color
, orfont
.selector
-@e[type=minecraft:allay]
json
-{"text": "Hello, World"}
keybind
- Any valid keybind. Should not include thekey.
.key.advancements
should be input asadvancements
.
Text is interpreted as exactly that, text. To format our text, we'll need to put it in what's called a text isolator, which is just text wrapped in square brackets. Then, we'll attach a modifier block to it. A modifier block is just a set of key value pairs (some exceptions apply) wrapped in parenthesis. For instance: (color=blue, bold=true)
is a modifier block. Attaching a text isolator and a modifier block is as simple as putting them next to each other, like so: [text](color=blue)
.
If more than one modifier needs to be specified, they should be separated by commas: (color=white, insertion="You shift clicked the chat")
Modifiers should always be a set of key and value pairs separated by an equal sign. The only exceptions to this are:
- Links are automatically inferred if they begin with
https://
orhttp://
- Hex codes are automatically interpreted as colors
bold
,italic
,strikethrough
,underlined
, andobfuscated
do not require=true
. Instead, you can just add the keywords. These two samples are equivalent:[text](bold=true, italic=true)
-[text](bold, italic)
.- Built-in colors do not require a
color
keyword.[text](black)
is valid.
Here's a full list of all valid modifiers and their expected types (not including the exceptions listed above):
hover_item
-json
, should describecontents.show_item
as demonstrated here.hover_text
-scope block
color
-color
orhex_code
link
-url
font
-string
copy
-font
suggest
-string
run
-string
insertion
-string
page
-integer
bold
-boolean
italic
-boolean
strikethrough
-boolean
underlined
-boolean
obfuscated
-boolean
Modifier blocks can also be applied to standalone blocks. Standalone blocks are used to show entity selectors, translation keys, keybinds, scoreboards, and NBT selectors. They are also given in key value pairs, however, unlike modifier blocks, multiple standalone blocks cannot be combined. Every individual component of a standalone block should be separated by commas.
Here is a list of all valid arguments in a standalone block:
selector
-selector
translate
-string
with
-json
nbt
-string
block/entity/storage
-string
, Selectors and coordinates should be put in strings as well ("@s"
/"83 76 239"
).interpret
-boolean
, follows the same rules as booleans in modifiers (=true
is optional. Justinterpret
is valid.)sep
orseparator
- Optional. Defines the string that should be inserted between entity/NBT selectors that target multiple values. Only used withnbt
andselector
.score
-string
. Must be followed by an arrow (->
) and another string containing the objective namekey
-keybind
All standalone arguments are non-order specific, but components that are invalid in-game will not return an error. For instance, mixing nbt
and selector
will give unintended results in game, but will be seen as valid to the parser. Be careful not to mix invalid items.
And some examples:
{@s}
{@s, sep=" - "}
{@s, separator=" - "}
{translate="k:ey"}
{translate="k:ey", with=["raw", "json"]}
{nbt="path", entity="@s"}
{nbt="path", block="88 72 239", sep=" : "}
{nbt="path", storage="store:age", sep="><"}
{score="DoubleF3lix" -> "playerKills"}
{score="@s"->"rightClick"}
{key=advancements}
{@s}(hover_text=<gone fancy>, #00aced)
Definitions
Allay also supports text reuse in the form of patterns and templates (collectively referred to as definitions). All definitions must be included at the top of the file and separated by a delimiter (#ALLAYDEFS\n
by default). Patterns can be identified by the @
symbol, and templates can be defined by the $
symbol. Both can be given custom names, but these names can only include letters, numbers, and underscores.
Patterns
Patterns let you reuse modifiers.
An example of their usage is as follows:
@pattern_name = (color=#000000, bold, hover_text=<Basically /clone>)
Here is some [modified text](@pattern_name)
In this case, [modified text](@pattern_name)
is equivalent to [modified text](color=#000000, bold, hover_text=<Basically /clone>)
.
However, merging patterns wither other modifiers is valid:
@pattern1 = (bold, italic)
@pattern2 = (underlined, bold=false)
More [text](@pattern1, @pattern2, link="https://example.com")
Patterns are applied in order that they are listed in from left to right.
In this case, [text](@pattern1, @pattern2, link="https://example.com")
is equivalent to [text](italic, underlined, link="https://example.com")
, as the bold
modifier in @pattern1
is overridden by @pattern2
.
Templates
The primary attribute of templates is that they let you reuse blocks of text, and they can take arguments:
$template_name = {A template can use [modifiers](underlined) like normal.
This template has %0 arguments.
By the way, you owe me $%1.00.}
Usage is as follows:
{$template_name, "2", "18,000"}
This would translate to
A template can use [modifiers](underlined) like normal.
This template has 2 arguments.
For instance, you owe me $18,000.00.
Arguments are done simply via find-replace, so take care to avoid using %<num>
in your text. Currently, they cannot be escaped. Any missing arguments will not be replaced (and left as %<num>
), and any extra arguments will be ignored. All arguments must be passed in as strings.
To use definitions in your text, do the following:
@pattern = ()
$template = {}
#ALLAYDEFS
Okay, back to the show.
The first blank line in-between the delimiter (#ALLAYDEFS\n
) and the text body is ignored. The delimiter cannot be escaped, so using it in your text will result in the definitions being ended prematurely and likely a syntax error. However, if this becomes an issue, you can change the delimiter by setting definition_delimeter
in allay.Parser()
.
Notes
The package comes with a beet plugin (created by rx). It is not officially supported, and any issues should be directed to its creator.
If you have any questions, need any help, etc., feel free to make an issue with your question.
