in-dexter

Automatically create a handcrafted index in typst. This typst component allows the automatic creation of an Index page with entries that have been manually marked in the document by its authors. This, in times of advanced search functionality, seems somewhat outdated, but a handcrafted index like this allows the authors to point the reader to just the right location in the document.

⚠️ Typst is in beta and evolving, and this package evolves with it. As a result, no backward compatibility is guaranteed yet. Also, the package itself is under development and fine-tuning.

Usage

Importing the Component

To use the index functionality, the component must be available. This can be achieved by importing the package in-dexter into the project:

Add the following code to the head of the document file(s) that want to use the index:

  #import "@preview/in-dexter:0.5.3": *

Alternatively it can be loaded from the file, if you have it copied into your project.

  #import "in-dexter.typ": *

Remarks for new version

In previous versions (before 0.0.6) of in-dexter, it was required to hide the index entries with a show rule. This is not required anymore.

Marking Entries

To mark a word to be included in the index, a simple function can be used. In the following sample code, the word “elit” is marked to be included into the index.

= Sample Text
Lorem ipsum dolor sit amet, consectetur adipiscing #index[elit], sed do eiusmod tempor
incididunt ut labore et dolore.

Nested entries can be created - the following would create an entry adipiscing with sub entry elit.

= Sample Text
Lorem ipsum dolor sit amet, consectetur adipiscing elit#index("adipiscing", "elit"), sed do eiusmod
tempor incididunt ut labore et dolore.

The marking, by default, is invisible in the resulting text, while the marked word will still be visible. With the marking in place, the index component knows about the word, as well as its location in the document.

Generating the Index Page

The index page can be generated by the following function:

= Index
#columns(3)[
  #make-index(title: none)
]

This sample uses the optional title, outline, and use-page-counter parameters:

#make-index(title: [Index], outlined: true, use-page-counter: true)

The make-index() function takes three optional arguments: title, outlined, and use-page-counter.

• title adds a title (with heading) and
• outlined is false by default and is passed to the heading function
• use-page-counter is false by default. If set to true it will use counter(page).display() for the page number text in the index instead of the absolute page position (the absolute position is still used for the actual link target)

If no title is given the heading should never appear in the layout. Note: The heading is (currently) not numbered.

The first sample emits the index in three columns. Note: The actual appearance depends on your template or other settings of your document.

You can find a preview image of the resulting page on in-dexter´s GitHub repository.

You may have noticed that some page numbers are displayed as bold. These are index entries which are marked as “main” entries. Such entries are meant to be the most important for the given entry. They can be marked as follows:

#index(fmt: strong, [Willkommen])

or you can use the predefined semantically helper function

#index-main[Willkommen]

Brief Sample Document

This is a very brief sample to demonstrate how in-dexter can be used. The next chapter contains a more fleshed out sample.

#import "@preview/in-dexter:0.5.3": *


= My Sample Document with `in-dexter`

In this document the usage of the `in-dexter` package is demonstrated to create
a hand picked #index[Hand Picked] index. This sample #index-main[Sample]
document #index[Document] is quite short, and so is its index.


= Index

This section contains the generated Index.

#make-index()

Full Sample Document

#import "@preview/in-dexter:0.5.3": *

#let index-main(..args) = index(fmt: strong, ..args)

// Document settings
#set page("a5")
#set text(font: ("Arial", "Trebuchet MS"), size: 12pt)


= My Sample Document with `in-dexter`

In this document #index[Document] the usage of the `in-dexter` package #index[Package]
is demonstrated to create a hand picked index #index-main[Index]. This sample document
is quite short, and so is its index. So to fill this sample with some real text,
let´s elaborate on some aspects of a hand picked #index[Hand Picked] index. So, "hand
picked" means, the entries #index[Entries] in the index are carefully chosen by the
author(s) of the document to point the reader, who is interested in a specific topic
within the documents domain #index[Domain], to the right spot #index[Spot]. Thats, how
it should be; and it is quite different to what is done in this sample text, where the
objective #index-main[Objective] was to put many different index markers
#index[Markers] into a small text, because a sample should be as brief as possible,
while providing enough substance #index[Substance] to demo the subject
#index[Subject]. The resulting index in this demo is somewhat pointless
#index[Pointless], because all entries are pointing to few different pages
#index[Pages], due to the fact that the demo text only has few pages #index[Page].
That is also the reason for what we chose the DIN A5 #index[DIN A5] format, and we
also continue with some remarks #index[Remarks] on the next page.


== Some more demo content without deeper meaning

#lorem(50) #index[Lorem]

#pagebreak()

== Remarks

Here are some more remarks #index-main[Remarks] to have some content on a second page, what
is a precondition #index[Precondition] to demo that Index #index[Index] entries
#index[Entries] may point to multiple pages.


= Index

This section #index[Section] contains the generated Index #index[Index], in a nice
two-column-layout.

#set text(size: 10pt)
#columns(2)[
    #make-index()
]

The following image shows a generated index page of another document, with additional formatting for headers applied.

More usage samples are shown in the document sample-usage.typ on in-dexter´s GitHub.

A more complex sample PDF is available there as well.

• fix error in typst.toml file.
• Add a sample for raw display.

v0.5.2

• Fix a bug with bang notation.
• Add compiler to toml file.

v0.5.1

• Migrate deprecated locate to context.

v0.5.0

• Support page numbering formats (i.e. roman), when use-page-counter is set to true. Thanks to @ThePuzzlemaker!

v0.4.3

• Suppress extra space character emitted by the index() function.
• Fix a bug where math formulas are not displayed.
• Introduce apply-casing parameter to index() to suppress entry-casing for individual entries.

v0.4.2

• Improve internal method as-text to be more robust.
• tidy up sample-usage.typ.

v0.4.1

• Bug fixed: Fix a bug where an index entry with same name as a group hides the group.
• Fixed typos in the sample-usage document.

v0.4.0

• Support for a display parameter for entries. This allows the usage of complex content, like math expressions in the index. (based on suggestions by @lukasjuhrich)
• Also support a tuple value for display and key parameters of the entry.
• Improve internal robustness and fix some errors in the sample document.

v0.3.2

• Fix initial parsing and returning fist letter (thanks to @lukasjuhrich, #14)

v0.3.1

• Fix handling of trailing or multiple spaces and crlf in index entries.

v0.3.0

• Support multiple named indexes. Also allow the generation of combined index pages.
• Support for LaTeX index group syntax (#index("Group1!Group2@Entry").
• Support for advanced case handling for the entries in the index. Note: The new default ist to ignore the casing for the sorting of the entries. The behavior can be changed by providing a sort-order() function to the make-index function.
• The casing for the index entry can also be altered by providing a entry-casing() function to the make-index function. So it is possible that all entries have an uppercase first letter (which is also the new default!).

v0.2.0

• Allow index to respect unnumbered physical pages at the start of the document (Thanks to @jewelpit). See “Skipping physical pages” in the sample-usage document.

v0.1.0

• big refactor (by @epsilonhalbe).
• changing “marker classes” to support direct format function fmt: content -> content e.g. index(fmt: strong, [entry]).
• Implemented:
  • nested entries.
