# Glossy
This package provides utilities to manage and render glossaries within
documents. It includes functions to define and use glossary terms, track their
usage, and generate a glossary list with references to where terms are used in
the document.

## Motivation
Glossy is heavily inspired by
[glossarium](https://typst.app/universe/package/glossarium), with a few key
different goals:
1. Provide a simple interface which allows for complete control over glossary
display. To do this, `glossy`'s `#glossary()` function accepts a theme
parameter. The goal here is to separate presentation and logic.
1. Simplify the user interface as much as possible. Glossy has exactly two
exports, `init-glossary` and `glossary`.
1. Double-down on `glossy`'s excellent `@term` reference approach, completely
eliminating the need to make any calls to `gls()` and friends.
1. Mimic established patterns and best practices. For example, `glossy`'s
`#glossary()` function is intentionally similar (in naming and parameters) to
`typst`'s built-int `#bibliography`, to the degree possible.
1. Simplify the implementation. The `glossy` code is significantly shorter and
easier to understand.
## Features
- Define glossary terms with short and long forms, descriptions, and grouping.
- Automatically tracks term usage in the document, making references simple
through @labels.
- Supports modifiers to adjust how terms are displayed (capitalize, pluralize,
etc.).
- Generates a formatted glossary section with backlinks to term occurrences in
the document.
- Easily customizable themes for rendering glossary sections, groups, and
entries.
## Usage
### Import the package
```typst
#import "@preview/glossy:0.1.0": *
```
### Defining Glossary Terms
Use the `init-glossary` function to initialize glossary entries and process
document content:
```typst
#let myGlossary = (
(
key: "html",
short: "HTML",
long: "Hypertext Markup Language",
description: "A standard language for creating web pages",
group: "Web"
),
(
key: "css",
short: "CSS",
long: "Cascading Style Sheets",
description: "A stylesheet language used for describing the presentation of a document",
group: "Web"
),
(
key: "tps",
short: "TPS",
long: "test procedure specification"
),
// Add more entries as needed
)
#show: init-glossary.with(myGlossary)
// Your document content here, where glossary terms are used.
```
Note that you could also load glossary entries from a data file using
[#yaml()](https://typst.app/docs/reference/data-loading/yaml/),
[#json()](https://typst.app/docs/reference/data-loading/json/), or
[similar](https://typst.app/docs/reference/data-loading/).
### Using Glossary Terms in Your Document
Use glossary terms within your text using the `@reference` functionality in
typst.
For example, `@html` and `@css` are used in the following text:
```typst
In modern web development, languages like @html and @css are essential.
Now make sure I get your @tps:short reports by 2pm!
```
... which should output:
```text
In modern web development, languages like Hypertext Markup Language (HTML) and
Cascading Style Sheets (CSS) are essential.
Now make sure I get your TPS reports by 2pm!
```
You can control how each term is displayed using the following modifiers:
- **cap**: Capitalizes the term.
- **pl**: Uses the plural form of the term.
- **both**: Displays both the long and short forms (e.g., "Long Form (Short Form)").
- **short**: Displays only the short form.
- **long**: Displays only the long form.
Each modifier is separated by a colon (':') character. Examples:
| **Input** | **Output** |
| ----------------------- | -------------------------------------------- |
| `@tps` (first use) | "technical procedure specification (TPS)" |
| `@tps` (subsequent use) | "TPS" |
| `@tps:short` | "TPS" |
| `@tps:long` | "technical procedure specification (TPS)" |
| `@tps:both` | "technical procedure specification (TPS)" |
| `@tps:long:cap` | "Technical procedure specification" |
| `@tps:long:pl` | "technical procedure specifications" |
| `@tps:short:pl` | "TPSes" |
| `@tps:both:pl:cap` | "Technical procedure specifications (TPSes)" |
Combine modifiers in any way you like. But know that if you combine any of
`short`, `long`, and/or `both`, only one will be used.
### Generating the Glossary
To display the glossary in your document, use the `glossary` function. Customize
the title and specify a theme if desired:
```typst
#glossary(title: "Web Development Glossary", theme: my-theme, groups: ("Web"))
```
### Themes
Customize the appearance of the glossary using themes. Each theme defines how
sections, groups, and entries are displayed.
- **section**: This is a main glossary section. It contains multiple glossary groups.
- **group**: A group within the main glossary section. Contains multiple
entries. Can be `none`.
- **entry**: A single entry within a group. This is the actual term, and can
include any of the fields in entry. Contains the following fields:
- `key`: The term key. (always present and unique)
- `short`: The short form of the term. (always present)
- `long`: The long form. (can be `none`)
- `description`: The description or definition. (can be `none`)
- `pages`: Pages with links to term usage in doc. (always present)
Example of a minimal theme:
```typst
#let my-theme = (
section: (title, body) => {
heading(level: 1, title)
body
},
group: (name, body) => {
if name != none and name != "" {
heading(level: 2, name)
}
body
},
entry: (entry, i, n) => {
// i is the entry's index, n is total number of entries
let output = [#entry.short]
if entry.long != none {
output = [#output -- #entry.long]
}
if entry.description != none {
output = [#output: #entry.description]
}
block(
grid(
columns: (auto, 1fr, auto),
output,
repeat([#h(0.25em) . #h(0.25em)]),
entry.pages,
)
)
}
)
```
