==Code with a Proper Text Editor==
+
'''Recommended Plugin: [[Roll20 Autouploader]]''' -- [[Browser#Plugins|browser plugin]] that can autoupload & update your sheet code in the sheet sandbox, so you don't have to do it manually each time. Can also do same for API scripts.
Rather than using the built-in code editor, all sheet authors who do sheets with any regularity use a separate text editor meant for coding, as they makes things much easier, and have tons of features  & extensions that are useful.
+
  
Some use an [https://en.wikipedia.org/wiki/Integrated_development_environment IDE], but due to Roll20 having a bunch of unique stuff, it's not really practical to test code locally. It's best to test the code live in a [[Sheet Sandbox]], or the [[Sheet Editor]].
+
==Tools==
 
+
See '''[[Character Sheet Development/Tools]]''' for community recommendations on sheet dev tools.
It's quicker to edit & save code on your computer, then upload the new sheet version to the [[Sheet Sandbox]] through the menu, than editing & using the [[Sheet Editor]].

'''User Cases'''
+
* make live edits on you sheet and see how things change(like adjusting the width of a [[Building_Character_Sheets#type.3D.22number.22|number input]] to look good)
+
* figure out why something works or doesn't work in your code, to narrow down the problem source (like why a css class is not working)
+
* reading the webdev console to figure out what's going on with your [[sheetworkers]]. (If you add <code>console.log("set strength mod to" + strmod)</code> to specific places in your code, you can see what steps are taken and what is left out)

{{main|Character Sheet Development/Pattern Libraries}}
  
A pattern library can be your best friend if you want to make multiple sheets. Component style programming will let you save styles to be reused between sheets. With my last project I put work into my {{repo|clevett/roll20-SheetTemplate Sheet Template}}. This saves me a good deal of time by not needing to start from scratch every time. Its a slow work in progress were I'm reinventing much of [[#Bootstrap|Bootstrap]].

</pre>
+
 
+
=== Sheet Versioning===
+
It can be beneficial to use a visible sheet version on a sheet, so people know when the sheet have updated. Also using sheet version will make it easier for you and others to track the state of the sheet and possible changelog.
+
 
+
If you have complex stat & sheetworkers in you sheet and make changes to them, it can be beneficial to add sheet versioning sheetworker that updates things for character using older version of the sheet to a new one.
+
 
+
An example would be to update an attribute name with a typo, to one with the correct spelling. The sheet versioning would next time a sheet is opened notice it is a older version, and then perform the sheet update transferring the attribute values of the old attribute to the new one, while it would do nothing on sheet that are already the latest version.

=== Documentation ===
 
The '''"Instructions"'''-section of the <code>sheet.json</code> is a bit unwieldy to fill out and structure(mix of normal [https://www.markdownguide.org/basic-syntax Markdown]-syntax, and using <code>/n</code> for line breaks), so it might be easier to place any larger documentation here on the Roll20 Community Wiki.
 
 
If the character sheet have several tabs or is long, the wiki could better fit more preview images of the sheet, rather than having something complicated on GitHub/the Sheet Template Preview.
 
 
* How to [[Help:Contents#Create_New_Page|create a new wiki page]]
 
* [[ExampleRPG]] - example page for sheet documentation
 
* '''[[:Category:Character Sheet Documentation]]''' - list of all Community Wiki pages for sheet instructions
 
 
Alternatively, add a <code>Readme.md</code>-file in the same folder with the sheet code, and then write sheet instructions using Markdown on it.
 
 
Link to the sheet's wiki page/readme in the "Instructions" (e.g. <code><nowiki>For sheet instructions, go to [ExampleRPG](https://wiki.roll20.net/ExampleRPG).</nowiki></code>.
 
 
* <code>sheet.json</code> {{repo|Roll20/roll20-character-sheets/blob/master/Supers-Revised-Edition/sheet.json example 1}} -ink to wiki page
 
* <code>sheet.json</code> {{repo|Roll20/roll20-character-sheets/blob/master/Log Horizon TRPG/sheet.json example 2}} link to github readme file
 
 
===Using REGEX===
 
One method of saving time with sheet dev is to use regex to find & replace more complex things in code.
 
 
{{ex}}
 
::'''Using REGEX to add Title code for attribute and roll names'''
 
::Many sheets do not tell users the different attribute names. The easiest method is to include a title="@{attrname}" in each input/select. Buttons could also benefit from adding a title="%{buttonname}" but isn't as big of a deal.
 
::It's possible to create a regex or some other syntax/replace command that could be run on any sheet that already doesn't have them, and add these attribute name tooltips for all attributes.
 
 
::'''Basic syntax to add Attribute titles''':
 
::find all: name="attr_REGEX"
 
::replace with: name="attr_REGEX" title="@{REGEX}"
 
 
::REGEX is replaced with regex commands or some other search syntax that search/accepts alphanumerals, -, _ (in essence, anything that's a valid attribute name)
 
 
::'''Basic syntax to add Roll buttons titles''':
 
::find all: name="roll_REGEX"
 
::replace with: name="roll_REGEX" title="%{REGEX}"
 
 
::'''Attribute example:'''
 
<pre data-language="html">
 
find regex: name="attr_([A-Za-z0-9_-]{1,50})"
 
replace regex: name="attr_$1" title="@{$1}"
 
</pre>
 
::'''Buttons example:'''
 
<pre data-language="html">
 
find regex: name="roll_([A-Za-z0-9_-]{1,50})"
 
replace regex: name="roll_$1" title="%{$1}"
 
</pre>
 
::(Arbitrarily chose "50" as max-length of attr name, use larger number if you might have super long names of course.)

This is a collection of more advanced Sheet Author Tips that currently doesn't fit on the other pages relating to character sheet creation & editing. Most of the suggestions & ideas are taken from the Roll20 forums, or discussions among Sheet Authors.

Sheet Author is a badge people who have created & submitted character sheets to Roll20 get.

Contents


[edit] Read the documentation

Give the Building Character Sheets-article a full read, as it contains lots of information on the specific quirks & pitfalls of how Roll20 character sheets works compared to default HTML/CSS/JavaScript. Even if you know how things work.

Some Highlights:

[edit] Sheet Sandbox

Using the Sheet Sandbox while editing/developing character sheets is much more effective and quicker than the normal Sheet Editor.

Alongside it, most authors use a text editor such as VS Code.

Recommended Plugin: Roll20 Autouploader -- browser plugin that can autoupload & update your sheet code in the sheet sandbox, so you don't have to do it manually each time. Can also do same for API scripts.

[edit] Tools

See Character Sheet Development/Tools for community recommendations on sheet dev tools.

[edit] Code Validation

It's a good idea to use a validator to check your code for mistakes in your code. Many IDE & text editors can install such extensions automatically, but given that Roll20 does a few things their own way, by default a HTML validator would complain about lot of things that aren't wrong, but just isn't accepted as standard HTML, such as <button type="roll"></button>.

Main Page: Roll20 Autouploader

Autouploader in action

Roll20 API and Sheet Autouploader is a Chromium extension that will automate the uploading of code to your Sheet Sandbox, created by Scott C..

This streamlines Character Sheet Development, removing the need to manually upload the files when you want to test changes. The extension will eventually work with API Development as well.


It should work on all chromium browsers except for Brave, which has disabled the chromium features that the extension relies on. n/CSS/Building_blocks/Debugging_CSS Debugging CSS]

[edit] Frameworks

Beyond just using HTML/CSS directly, you could use some pre-processors, language extensions, or frameworks that can speed up the sheet development, instead of directly writing HTML/CSS. Here are a few suggestions, used by a good number of sheet authors, including Roll20's teams working on the official sheets.

Use PUG & SASS/SCSS & JavaScript to make sheets. PUG & SCSS are the two most useful things I've ever learned for sheet development. Character sheets which use to take hundred+ hours takes now 20-40 thanks to PUG which is a JavaScript based language to write HTML. You'll save yourself a lot of redundant work by just using the power of loops & variables if nothing else.
Troubleshooting becomes much easier when you need to fix just one line in a loop rather than a dozen copy/paste html snippets.
PUG and SCSS can be used to simply split up the HTML & CSS files into smaller, more manageable files, which can then simply be compiled into their end results when it's time to use the sheet in a game.
These are compiled languages so you'll need to do that. Easily done via terminal if your tech savy, or prepros.io if you're not.

[edit] PUG

PUG is a template engine for generating HTML, where you can use various features & tool to write code more efficiently, such as using variables and loops, and has a simpler syntax.

[edit] SASS

SASS/SCSS is a widely used CSS extension language. It's CSS Compatible, so you can start using it by writing plain CSS first, and slowly including more SASS features, while keeping it familiar & looking mostly like CSS.

One of the things you can do it to nest your code, saving you from repeating yourself with things like needing to add .charsheet in from of every class.

/*-------------------------------------------*/
/*-----Main Settings and hide classes--------*/
// comments with two slashes won't appear in the resulting .css,  which is handy for writing extra comments thaat aren't relevant to the css.
// SCSS enables nesting of classes, saving time in writing, and making it easier to read/organize the CSS. There are also tother features,but this is the main one I've started to use, as it helps with reading the scss/css. One can start from pure css, and then bit by bit simplify/refactor it to use more scss features
.charsheet {
	.main-settings {
	    display: none;
		position: relative;
		margin-left: 0;
		
		.container {
			width: 850px;
		}
		.input-row {
			label {
				display: inline-block;
				width: auto;
			}
			input {
				margin-right: 30px;
			}
			select {
				width: 45%;
				margin-right: 15px;
			}
		}
	}
  input.main-options.options-flag + span,/*displays the cog icon*/
  input[type=radio]:checked ~ .master-container input.options-flag + span {
      font-family: pictos;
      font-style: normal;
  }
}

resulting CSS:

/*-------------------------------------------*/
/*-----Main Settings and hide classes--------*/
.charsheet .main-settings {
  display: none;
  position: relative;
  margin-left: 0;
}
.charsheet .main-settings .container {
  width: 850px;
}
.charsheet .main-settings .input-row label {
  display: inline-block;
  width: auto;
}
.charsheet .main-settings .input-row input {
  margin-right: 30px;
}
.charsheet .main-settings .input-row select {
  width: 45%;
  margin-right: 15px;
}
.charsheet input.main-options.options-flag + span,
.charsheet input[type=radio]:checked ~ .master-container input.options-flag + span {
  font-family: pictos;
  font-style: normal;
}

[edit] Handlebars

Suggestion by Primal Zed

thread(Forum)

Pros:

  • Looks like HTML (or whatever file type you're templating), with handlebars blocks added in
  • Inject data values anywhere directly into the HTML
  • Can yield benefit with little effort - sheet authors can use as much or as little as they want
  • Handlebars blocks have opening and close tags similar to HTML
  • Easy to add new templates for re-use and organization

Cons:

  • Involves new syntax to learn and helpers to understand
    • Built-In Helpers
    • For advanced use: Additional Helpers
    • For advanced use: Repeat Helper
  • Requires Node.js installation and some command lines

[edit] Bootstrap

There are a number of sheets in the repository that have been built with Bootstrap, but using it for sheet development is a bit on the heavy side, and can have a higher bar to get started with than only using pre-prosessors like PUG and SASS.

[edit] Git/GitHub

[edit] Install the Pull App to GitHub

Pull App is a GitHub bot that can automatically watch and pull in Roll20's upstream default master-branch to your fork using hard reset every few hours. You can also manually trigger it anytime.

Failure to keep your GitHub fork in sync with the master repo can create merge conflicts causing a pull request to be rejected or delayed. The Pull App can help automate this process and keep your fork in sync with Roll20's master-branch.

While the Pull App will sync in the background every few hours, it is recommended that you manually run the bot before creating a branch for editing to ensure your fork's master-branch is in sync with Roll20's most current master-branch.

[edit] Use Branches in GitHub

Do not make changes to your GitHub master-branch. Instead make a branch from master to do all upgrades there. Submit pull request to the Roll20 repo directly from a branch. This is a safe way to do version control and will improve the integrity of your work.

[edit] Advanced Sheet Features

[edit] Statblock Importer

Some sheets have integrated options to import sheets to Roll20, such as for plaintext or .json statblocks.

Existing Sheets with integrated import functions, by format:


Some sheets have instead a separate API for this purpose, such as Earthdawn by FASA character sheet companion, Script:HL-Import and Script:HeroLabImporter.

[edit] GM Screen

Sometimes just an NPC sheet isn't enough, and it would be beneficial for the GM to have a GM Screen built into the sheet.

[edit] Changelog and Update Notification inside Sheet

The GURPS sheet displaying the latest sheet update notice.

If you a lots of changes to a sheet, or want to make sure that all users of the sheet are informed of the updates, you could integrate the sheet changelog & notification into the sheet, so next time they open a sheet their sheet they seem the update notice, & can dismiss them at will.

Alternatively, the changelog could be placed on a separate tab, such as folded it into the Settings-tab

The team behind the GURPS character sheet is a great example of incorporating a comprehensive changelog into the sheet, with a collapsible notice of the latest update/message from the sheet authors, and is non-obstructive even when not dismissed.


[edit] Sharing code/collaboration

If you need to share larger parts of a sheets code with others on the Roll20 forums or somewhere else quickly, using GitHub Gist to share the full sheet is a smart alternative to Dropbox/Google Drive/Pastebin.

The "Revisions" tab of a gist shows clearly code changes between revisions, so tracking what have changed makes things easier for you and others.

  • hilite.me can be used to convert your code to pretty html-formatted code that's very clear when copypasted to the forums. (Trick by The Aaron)
