Glulx Text Effects provides an easy way to set up special text effects for Glulx. Chapter: Styles in Glulx Unlike the Z-Machine, which allows arbitrary combinations of features (such as color and boldness) to be applied to text, Glulx requires the author to define and then use text styles. There are eleven of these styles: Table of styles
normal-style the style used for regular text
italic-style used for italic text (this is what the "[italic type]" phrase uses)
bold-style used for bold text (this is what the "[bold type]" phrase uses)
fixed-letter-spacing-style used for monospaced text (this is what the "[fixed letter spacing]" phrase uses)
alert-style used when printing an end of game message such as "*** You have died. ***"
blockquote-style used for printing box quotations
header-style used to print the title of the game
input-style used for the player's own input
note-style used for messages such as "[Your score has increased by one point.]"
special-style-1 these two styles are not used by Inform, and you are free to use them for any purpose you want
special-style-2
Additionally, when defining styles you can set "all-styles" which will define all eleven styles at once. Chapter: Style features Each text style has the following features: Table of style features
background color specifies the background color of the text
color specifies the color of the text itself
fixed width a truth state (default: false). If true then the text will be displayed with a fixed width (monospace) font
font weight specifies the weight of the font. Can be set to "light-weight", "regular-weight" (the default), or "bold-weight"
indentation a number (default: 0) specifying the number of units of indentation for the whole block of text. Units are defined by interpreter, but are often equivalent to spaces
first line indentation a number (default: 0) specifying additional indentation for the first line of the text block
italic a truth state (default: false). If true then the text will be displayed in italics
justification can be set to "left-justified", "center-justified", "right-justified", or "left-right-justified" for justified on the left and right (often called full justification)
relative size a number (default: 0) specifying how many font sizes above or below the browser's default a style should be set to
reversed a truth state (default: false). If true then the foreground and background colors of the text will be reversed. This is most commonly used for the status line
Not all interpreters support all of these features. Notably, Gargoyle does not support justification or font sizes. If the interpreter does not support one of the features it will just be quietly ignored. Chapter: Defining styles To define the features each style should have, add a table continuation to the Table of User Styles in your code. For example: Table of User Styles (continued)
style name color italic relative size
all-styles "#FF0000" true --
header-style "#0000FF" false 1
special-style-1 "#00FF00"
This definition table above will make everything red and italics, except for the title which will be blue and a size bigger. Special style 1 is set to green, but it won't be used without the author manually turning it on. Your table continuation does not need to include every column in the Table of User Styles, nor does it need to define every style. You can also continue the table multiple times, and even define a style in multiple places; if you do then the definitions will be combined together. If you do not want to set a feature for a style you can leave it blank with "--". Colors are defined by specifying a web (CSS) color in a text. Web colors specify the red/green/blue components of a color in hexadecimal, and a correctly specified color will be 6 characters long (with an optional # at the beginning.) Note that short (#000) web colors are not supported. If you use a color many times you can define it as a text constant, and then use that in the table: Red is always "#FF0000".

style name color
special-style-1 red
Chapter: Using the styles You may invoke the text styles by using the following phrases Table of style phrases
normal-style "[roman type]"
italic-style "[italic type]"
bold-style "[bold type]"
fixed-letter-spacing-style "[fixed letter spacing]" (Return to regular variable spaced type with either "[variable letter spacing]" or just "[roman type]")
alert-style "[alert style]"
blockquote-style "[blockquote style]"
header-style "[header style]"
input-style "[input style]"
note-style "[note style]"
special-style-1 "[special-style-1]", "[first special style]", or "[first custom style]" (there are multiple options to support older code)
special-style-2 "[special-style-2]", "[second special style]", or "[second custom style]"

Instead of waiting: increase the score by 5. Instead of jumping: end the story finally. Every turn: display the boxed quotation "Tempus fugit." Test me with "z / z / z / jump".

>--> Some source text ended in the middle of quoted text: main source text. This probably means that a quotation mark is missing somewhere. If you are using Inform with syntax colouring, look for where the quoted-text colour starts. (Sometimes this problem turns up because a piece of quoted text contains a text substitution in square brackets which in turn contains another piece of quoted text - this is not allowed, and causes me to lose track.) Because of this problem, the source could not be translated into a working game. (Correct the source text to remove the difficulty and click on Go once again.)

Version 5/150123 of Glulx Text Effects (for Glulx only) by Emily Short begins here. "Gives control over text formatting in Glulx." [ Version 5 was rewritten by Dannii Willis ] Use authorial modesty. Chapter - Specifying styles [ It is important that the values be specified precisely in the following orders, because otherwise the I6 assumptions about the relation of named values to number constants will be wrong. ] A glulx text style is a kind of value. The glulx text styles are all-styles, normal-style, italic-style, fixed-letter-spacing-style, header-style, bold-style, alert-style, note-style, blockquote-style, input-style, special-style-1 and special-style-2. A text justification is a kind of value. The text justifications are left-justified, left-right-justified, center-justified, and right-justified. A font weight is a kind of value. The font weights are light-weight, regular-weight, and bold-weight. Section - The Table of User Styles definition [ This table is given its own section so that it can be replaced to add extra columns needed by other extensions (such as Flexible Windows) ] Table of User Styles
