How to Convert a Legacy Document to v3

Here you will find a number of steps to guide you through converting a Legacy document into a Homebrewery v3 document.

The first thing you'll want to do is switch the editor's rendering engine from Legacy to v3. This will be the renderer we design features for moving forward.

There are some examples of Legacy code in the code pane if you need more context behind some of the changes.

This document will evolve as users like yourself inform us of issues with it, or areas of conversion that it does not cover. Please reach out if you have any suggestions for this document.

Simple Replacements

To make your life a little easier with this section, a text editor like VSCode or Notepad will help a lot.

The following table describes Legacy and other document elements and their Homebrewery counterparts. A simple find/replace should get these in working order.

Legacy / Other Homebrewery
\pagebreak \page
====== \page
\pagebreaknum {{pageNumber,auto}}\n\page
@===== {{pageNumber,auto}}\n\page
\columnbreak \column
.phb .page

Classed or Styled Divs

Anything that relies on the following syntax can be changed to the new Homebrewery v3 curly brace syntax:

<div class="classTable wide">
...
</div>

: The above example is equivalent to the following in v3 syntax.

{{classTable,wide
...
}}

: Some examples of this include class tables (as shown above), descriptive blocks, notes, and spell lists.

\column

Margins and Padding

Any manual margins and padding to push text down the page will likely need to be updated. Colons can be used on lines by themselves to push things down the page vertically if you'd rather not set pixel-perfect margins or padding.

Notes

In Legacy, notes are denoted using markdown blockquote syntax. In Homebrewery v3, this is replaced by the curly brace syntax.

{{note

Title

Information }}

Split Tables

Split tables also use the curly brace syntax, as the new renderer can handle style values separately from class names.

Typical Difficulty Classes

{{column-count:2

Task Difficulty DC
Very easy 5
Easy 10
Medium 15
Task Difficulty DC
Hard 20
Very hard 25
Nearly impossible 30
}}

Blockquotes

Blockquotes are denoted by the > character at the beginning of the line. In Homebrewery's v3 renderer, they hold virtually no meaning and have no CSS styling. You are free to use blockquotes when styling your document or creating themes without needing to worry about your CSS affecting other parts of the document.

Stat Blocks

There are pretty significant differences between stat blocks on the Legacy renderer and Homebrewery v3. This section contains a list of changes that will need to be made to update the stat block.

Initial Changes

You will want to remove all leading ___ that started the stat block in Legacy, and replace that with {{monster before the stat block, and }} after it.

If you want a frame around the stat block, you can add ,frame to the curly brace definition.

If the stat block was wide, make sure to add ,wide to the curly brace definition.

Blockquotes

The key difference is the lack of blockquotes. Legacy documents use the > symbol at the start of the line for each line in the stat block, and the v3 renderer does not. You will want to remove all > characters at the beginning of all lines, and delete any leading spaces.

Lists

The basic characteristics and advanced characteristics sections are not list elements in Homebrewery. You will want to remove all - or * characters from the beginning of lines.

Spacing

In order to have the correct spacing after removing the list elements, you will want to add two colons between the name of each basic/advanced characteristic and its value. (see example in the code pane)

Additionally, in the special traits and actions sections, you will want to add a colon at the beginning of each line that separates a trait/action from another, as seen below. Any empty lines between special traits and actions should contain only a colon. (see example in the code pane)

\column

{{margin-top:102px}}

Homebrewery v3 Example:

{{monster

Centaur

Large monstrosity, neutral good


Armor Class :: 12 Hit Points :: 45(6d10 + 12) Speed :: 50ft.


STR DEX CON INT WIS CHA
18 (+4) 14 (+2) 14 (+2) 9 (-1) 13 (+1) 11 (+0)

Skills :: Athletics +6, Perception +3, Survival +3 Senses :: passive Perception 13 Languages :: Elvish, Sylvan Challenge :: 2 (450 XP)


Charge. If the centaur moves at least 30 feet straight toward a target and then hits it with a pike attack on the same turn, the target takes an extra 10 (3d6) piercing damage. : Second Thing More details.

Actions

Multiattack. The centaur makes two attacks: one with its pike and one with its hooves or two with its longbow. : Pike. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 9 (1d10 + 4) piercing damage. : Hooves. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) bludgeoning damage. : Longbow.
