WireText is a text format that allows you to rapidly create low fidelity user interfaces mockups. This VSCode extensions gives you a live preview of the mockups.
Features:
- A HTML/CSS templating language (inspired by PugJS) with a very lean syntax.
- A library of common user-interface components, using a hand-drawn style so that nobody mistakes your wireframes for polished layout mockups.
- As-you-type previews and error feedback.
- Automatic scrolling of the preview panel.
WireText is not offered in the VSCode market place yet. You can install it by downloading this file and installing it in VSCode by clicking ··· in the top-right of the extensions panel, and then selecting Install from VSIX...
This section is autogenerated from the component-examples.wt example file. If you want to get started with WireText quickly, we recommend you install the extension and open that file. Contrary to this Markdown document, that will provide you with syntax highlighting and an easy way to play around.

A Phone is a type of screen. It must have an id, which can be used to link to it from other screens.
Phone id=login title="Welcome to Thingies"
Input label=Email value="test@example.com"
Input label=Password value=123456 type=password
Button content="Sign in" link=home
Screens will often have some associated notes.
Phone id=login title="Welcome to Thingies" notes="""
These are the notes for this screen.
- Notes are written in *Markdown*.
- They can be used to describe **behavior** associated with the screen.

This section is autogenerated from the language-tutorial.wt example file. If you want to get started with WireText quickly, we recommend you install the extension and open that file. Contrary to this Markdown document, that will provide you with syntax highlighting and an easy way to play around.
The WireText language is an HTML templating language (inspired by PugJS). The following will create a <section> containing an <h3> with some text and a <ul> with two list items (the second one being a link):
section
h3
"Title text"
ul
li
"Item one."
li
a
"Item two."
# This is a comment.
When the content block for an element has only one item, it can be added to the same line, like this:
section
h3 "Title text"
ul
li "Item one."
li a "Item two."
HTML attributes can be provided using key=value pairs immediately after the tag name. Keys and values that contain 'strange' characters need to be "quoted" as a string.
section class=intro
h3 id=my_title style="color: red;" "Title text"
ul
li "Item one."
li a target=_blank href="https://example.com/two" "Item two."
As the class attribute is quite common, there's a shortcut for setting it:
section.intro "Intro"
section.intro.summary "Intro summary"
When the tag name is left out, 'div' is assumed:
.some_class "I'm a <DIV>"
Multi-line strings are supported using """triple double quotes""":
pre style="""
background-color: #222;
color: #fde;
""" title="Shell script"
"""
#!/bin/sh
files=`ls ~ | wc -l`
echo You have $files files in your home directory.
"""
For styling, we recommend the use of CSS instead of 'style' attributes. WireText offers a convenient syntax for defining CSS inline:
css
.special
background-color="#cce"
padding="8px"
.special > h3
color=red
.special li a
color=green
section class=special
h3 id=my_title "Title text"
ul
li "Item one."
li a target=_blank href="https://example.com/two" "Item two."
CSS selectors can be nested, and property=value pairs can optionally be put on the same line as the selector, allowing the above CSS to be written like this:
css .special background-color="#eee" padding="8px"
> h3 color=red
li a color=green
WireText allows you to define reusable components. Component names must start with a Capital Letter.
define YourName
fieldset
legend "Who are you?"
input placeholder="First name"
input placeholder="Last name"
To show a component, you can use its name as if it were an HTML tag:
YourName
.special
YourName
Components can have parameters, defined between (parenthesis) after the tag name. They must be provided when instantiating the component the same way that HTML attributes are provided. They can be used in most contexts (including within strings) by surrounding their names with {curly brackets}.
define AnyName(title, pronoun)
fieldset
legend {title}
input placeholder="{pronoun} first name"
input placeholder="{pronoun} last name"
AnyName title="Who is the king of pop?" pronoun=His
AnyName title="Who am I?" pronoun=My
Parameters are required, unless they get a default value, provided by a '=' and the value after the definition.
define AnyName(title = "Who are you?", pronoun = Your)
fieldset
legend {title}
input placeholder="{pronoun} first name"
input placeholder="{pronoun} last name"
AnyName
AnyName pronoun=Thy
Expression between {curly brackets} cannot just be parameter names, but are actually JavaScript expressions, in a context where all parameters have been defined as local variables
define AnyName(title = "Who are you?", pronoun = Your)
fieldset
legend {title.toUpperCase()}
input placeholder="{pronoun.replace(/o/, '😁')} first name"
input placeholder="{pronoun} last name"
AnyName
Component attributes names must be valid JavaScript variable names. In case you want to use a JavaScript keyword, such as class or inm as an attribute, you can suffix it with and underscore in the definition and in your JavaScript expressions.
define InClass(class_, in_)
input value={in_} class={class_}
InClass in=test class=intro
WireText supports the spread operator, to receive all attributes that have not been defined as parameters into an object. This object can be passed expanded to attributes for a DOM element or another component.
define SpreadComponent(a, b, ...rest)
p "a = {a}"
p "b = {b}"
p "rest has {Object.keys(rest).length} properties"
input ...rest
SpreadComponent a=Almond b=Banana style="color: red;" value="My input value" type=password
WireText offers if/else if/else blocks, where the condition is provided by a JavaScript expression. Also note how the '?' suffix in the parameter list can be used for optional parameters (defaulting to an empty string).
define AnyName(title = "Who are you?", checkbox?)
fieldset
legend {title}
input placeholder="First name"
input placeholder="Last name"
if {checkbox}
label
input type=checkbox
{checkbox}
AnyName
AnyName checkbox="I agree!"
Similarly, there are for blocks.
for person in {"he she Frank".split(" ")}
AnyName title="Who is {person}?"
JavaScript can also be used in event handlers, allowing you to hack a little bit of interactivity into your wireframes. NOTE: Expect this feature to change at any time. I'm not really happy with it yet.
button onclick={e => e.target.innerText += "!"} "Hello"
You may also run a bit of JavaScript while your page is initially constructed using a run statement. Its this variable will refer to the parent DOM element. NOTE: Expect this feature to change at any time. I'm not really happy with it yet.
css .angry color=red text-transform=uppercase font-weight=bold
section
"Test"
run {setInterval(() => this.classList.toggle('angry'), 500)}
(Multi-line) JavaScript containing {curly brackets} can be wrapped in {{{triple curly brackets}}}. While in {regular form} only a single JavaScript expression is expected, which will be used as a value by WireText, {{{triple form}}} doesn't deliver a value by default, but you can return one if you want.
section
"Test"
run {{{
let element = this;
function toggleAngry() {
element.classList.toggle('angry');
}
setInterval(toggleAngry, 500);
}}}
Components can also receive a block of WireText as a parameter. The default block (which resembles the content of a DOM element) is called 'content'.
define FancyFrame(content)
div style="border: 4px solid #c0c;"
div style="border: 4px solid #0cc;"
div style="border: 4px solid #cc0; padding: 4px;"
{content}
FancyFrame
"Type something: "
input
FancyFrame "test"
You can also pass multiple blocks as parameters, or pass a block to a parameter not named 'content' using this form:
css header display=flex background-color="#ccc" align-items=center
> h3 flex=1 text-align=center
define TitleBar(title, left, right)
header
.left {left}
h3 {title}
.right {right}
TitleBar title="Hello world!"
left=
a href="#" "Go back"
right=
input type=checkbox
"Dark mode"
FancyFrame
content = select
option "moon"
option "mars"
WireText allows you to include files. The path should be given as a string and relative to the path of the current file.
include "language-tutorial-include.wt"
IncludeHello
WireText standard libraries (currently only components-v1) can be included by giving the name as an identifier:
include components-v1
Phone id=test title="My app" up=home
content=
Input label=Name
CheckBox label="Sure!"
bar_right=
RemixIcon icon=settings
