MCI Codes

ENiGMA½ supports a variety of MCI codes. Some predefined codes produce information about the current user, system, or other statistics while others are used to instantiate a View.

General Information

MCI codes are composed of two characters and are prefixed with a percent (%) symbol.

ℹ️ To explicitly tie a MCI to a specific View ID, suffix the MCI code with a number. For example: %BN1.

ℹ️ Standard (non-focus) and focus colors are set by placing duplicate codes back to back in art files:

Some MCI codes have additional options that may be set directly from the code itself while others -- and more advanced options -- are controlled via the current theme.

Relationship with Menus, Art, and Themes

A MCI code that appears in a menu.hjson entry corresponds to that found in it's associated art file. This same MCI code can be referenced in the theme.hjson in order to apply a theme.

See Menus and Themes for more information.

Predefined Codes

There are many predefined MCI codes that can be used anywhere on the system (placed in any art file).

ℹ️ More are added all the time so also check out core/predefined_mci.js for a full listing.

📝 Many codes attempt to pay homage to Oblivion/2, iNiQUiTY, etc.

Views

A View is a control placed on a form that can display variable data or collect input. One example of a View is a Vertical Menu (%VM): Old-school BBSers may recognize this as a lightbar menu.

Code	Name	Description	Notes

BT	Button	A button	...it's a button. See Button
VM	Vertical Menu	A vertical menu	AKA a vertical lightbar; Useful for lists. See Vertical Menu
HM	Horizontal Menu	A horizontal menu	AKA a horizontal lightbar. See Horizontal Menu
FM	Full Menu	A menu that can go both vertical and horizontal.	See Full Menu
SM	Spinner Menu	A spinner input control	Select one from multiple options. See Spinner Menu
TM	Toggle Menu	A toggle menu	Commonly used for Yes/No style input. See Toggle Menu
PL	Predefined Label	Show environment information	See Predefined Label
KE	Key Entry	A single key input control	Think hotkeys

ℹ️ Peek at /core/mci_view_factory.js to see additional information.

Mask Edits

Mask Edits (%ME) use the special maskPattern property to control a mask. This can be useful for gathering dates, phone numbers, so on.

maskPattern's can be composed of the following characters:

• #: Numeric 0-9
• A: Alpha a-z, A-Z
• @: Alphanumeric (combination of the previous patterns)
• &: Any "printable" character

Any other characters are literals.

An example of a mask for a date may look like this: ##/##/####.

Additionally, the following theme stylers can be applied:

• styleSGR1: Controls literal character colors for non-focused controls
• styleSGR2: Controls literal character colors for focused controls
• styleSGR3: Controls fill colors (characters that have not yet received input).

All of the style properties can take pipe codes such as |00|08.

View Identifiers

As mentioned above, MCI codes can (and often should) be explicitly tied to a View Identifier. Simply speaking this is a number representing the particular view. These can be useful to reference in code, apply themes, etc.

A view ID is tied to a MCI code by specifying it after the code. For example: %VM1 or %SM10.

Properties & Theming

Predefined MCI codes and other Views can have properties set via menu.hjson and further themed via theme.hjson. See Themes for more information on this subject.

Common Properties

Property	Description
textStyle	Sets the standard (non-focus) text style. See Text Styles below
focusTextStyle	Sets focus text style. See Text Styles below.
itemSpacing	Used to separate items in menus such as Vertical Menu and Horizontal Menu Views.
height	Sets the height of views such as menus that may be > 1 character in height
width	Sets the width of a view
focus	If set to true, establishes initial focus
text	(initial) text of a view
submit	If set to true any accept action upon this view will submit the encompassing form
itemFormat	Sets the format for a list entry. See Entry Formatting below
focusItemFormat	Sets the format for a focused list entry. See Entry Formatting below

These are just a few of the properties set on various views. Use the source Luke, as well as taking a look at the default menu.hjson and theme.hjson files!

Custom Properties

Often a module will provide custom properties that receive format objects (See Entry Formatting below). Custom property formatting can be declared in the config block. For example, browseInfoFormat10...N (where N is up to 99) in the file_area_list module received a fairly extensive format object that contains {fileName}, {estReleaseYear}, etc.

Text Styles

Standard style types available for textStyle and focusTextStyle:

Style	Description
normal	Leaves text as-is. This is the default.
upper	ENIGMA BULLETIN BOARD SOFTWARE
lower	enigma bulletin board software
title	Enigma Bulletin Board Software
first lower	eNIGMA bULLETIN bOARD sOFTWARE
small vowels	eNiGMa BuLLeTiN BoaRD SoFTWaRe
big vowels	EniGMa bUllEtIn bOArd sOftwArE
small i	ENiGMA BULLETiN BOARD SOFTWARE
mixed	EnIGma BUlLEtIn BoaRd SOfTWarE (randomly assigned)
l33t	3n1gm4 bull371n b04rd 50f7w4r3

Entry Formatting

Various strings can be formatted using a syntax that allows width & precision specifiers, text styling, etc. Depending on the context, various elements can be referenced by {name}. Additional text styles can be supplied as well. The syntax is largely modeled after Python's string format mini language.

Additional Text Styles

Some of the text styles mentioned above are also available in the mini format language:

Style	Description
normal	Leaves text as-is. This is the default.
toUpperCase or styleUpper	ENIGMA BULLETIN BOARD SOFTWARE
toLowerCase or styleLower	enigma bulletin board software
styleTitle	Enigma Bulletin Board Software
styleFirstLower	eNIGMA bULLETIN bOARD sOFTWARE
styleSmallVowels	eNiGMa BuLLeTiN BoaRD SoFTWaRe
styleBigVowels	EniGMa bUllEtIn bOArd sOftwArE
styleSmallI	ENiGMA BULLETiN BOARD SOFTWARE
styleMixed	EnIGma BUlLEtIn BoaRd SOfTWarE (randomly assigned)
styleL33t	3n1gm4 bull371n b04rd 50f7w4r3

Additional text styles are available for numbers:

Style	Description
sizeWithAbbr	File size (converted from bytes) with abbreviation such as 1 MB, 2.2 GB, 34 KB, etc.
sizeWithoutAbbr	Just the file size (converted from bytes) without the abbreviation. For example: 1024 becomes 1.
sizeAbbr	Just the abbreviation given a file size (converted from bytes) such as MB or GB.
countWithAbbr	Count with abbreviation such as 100 K, 4.3 B, etc.
countWithoutAbbr	Just the count
countAbbr	Just the abbreviation such as M for millions.
durationHours	Converts the provided hours value to something friendly such as 4 hours, or 4 days.
durationMinutes	Converts the provided minutes to something friendly such as 10 minutes or 2 hours
durationSeconds	Converts the provided seconds to something friendly such as 23 seconds or 2 minutes

Examples

Suppose a format object contains the following elements: userName and affils. We could create a itemFormat entry that builds a item to our specifications: |04{userName!styleFirstLower} |08- |13{affils}. This may produce a string such as this:

💡 Remember that a Python string format mini language style syntax is available for widths, alignment, number prevision, etc. as well. A number can be made to be more human readable for example: {byteSize:,} may yield "1,123,456".
