:warning: ***IMPORTANT!*** Before making any customisations, create your own copy of `/config/menu.hjson`, and specify it in the `general` section of `config.hjson`:
|
|
|
|
````hjson
|
|
general: {
|
|
menuFile: yourboardname.hjson
|
|
}
|
|
````
|
|
This document and others will refer to `menu.hjson`. This should be seen as an alias to `yourboardname.hjson`
|
|
|
|
## The Basics
|
|
Like all configuration within ENiGMA½, menu configuration is done in [HJSON](https://hjson.org/) format.
|
|
|
|
Entries in `menu.hjson` are objects or _sections_ defining a menu. A menu in this sense is something the user can see or visit. Examples include but are not limited to:
|
|
|
|
* Classical Main, Messages, and File menus
|
|
* Art file display
|
|
* Module driven menus such as door launchers and other custom mods
|
|
|
|
Menu entries live under the `menus` section of `menu.hjson`. The *key* for a menu is it's name that can be referenced by other menus and areas of the system.
|
|
|
|
## Common Menu Entry Members
|
|
* `desc`: A friendly description that can be found in places such as "Who's Online" or the `%MD` MCI code.
|
|
* `art`: An art file specification.
|
|
* `next`: Specifies the next menu to go to next. Can be explicit or an array of possibilites dependent on ACS. See **Flow Control** in the **ACS Checks** section below.
|
|
* `prompt`: Specifies a prompt, by name, to use along with this menu.
|
|
* `form`: Defines one or more forms available on this menu.
|
|
* `submit`: Defines a submit handler when using `prompt`.
|
|
* `config`: May contain any of the following standard configuration members in addition to per-module defined types (see appropriate module for more information):
|
|
* `cls`: If `true` the screen will be cleared before showing this menu.
|
|
* `pause`: If `true` a pause will occur after showing this menu. Useful for simple menus such as displaying art or status screens.
|
|
* `nextTimeout`: Sets the number of **milliseconds** before the system will automatically advanced to the `next` menu.
|
|
* `baudRate`: Sets the SyncTERM style emulated baud rate. May be `300`, `600`, `1200`, `2400`, `4800`, `9600`, `19200`, `38400`, `57600`, `76800`, or `115200`. A value of `ulimited`, `off`, or `0` resets (disables) the rate. See [this specification](https://github.com/protomouse/synchronet/blob/master/src/conio/cterm.txt) for more information.
|
|
* `font`: Sets the SyncTERM style font. May be one of the following: `cp437`, `cp1251`, `koi8_r`, `iso8859_2`, `iso8859_4`, `cp866`, `iso8859_9`, `haik8`, `iso8859_8`, `koi8_u`, `iso8859_15`, `iso8859_4`, `koi8_r_b`, `iso8859_4`, `iso8859_5`, `ARMSCII_8`, `iso8859_15`, `cp850`, `cp850`, `cp885`, `cp1251`, `iso8859_7`, `koi8-r_c`, `iso8859_4`, `iso8859_1`, `cp866`, `cp437`, `cp866`, `cp885`, `cp866_u`, `iso8859_1`, `cp1131`, `c64_upper`, `c64_lower`, `c128_upper`, `c128_lower`, `atari`, `pot_noodle`, `mo_soul`, `microknight_plus`, `topaz_plus`, `microknight`, `topaz`. See [this specification](https://github.com/protomouse/synchronet/blob/master/src/conio/cterm.txt) for more information.

## Example
|
|
Let's look a couple basic menu entries:
|
|
|
|
```hjson
|
|
telnetConnected: {
|
|
art: CONNECT
|
|
next: matrix
|
|
options: { nextTimeout: 1500 }
|
|
}
|
|
```
|
|
|
|
The above entry `telnetConnected` is set as the Telnet server's first menu entry (set by `firstMenu` in the Telnet server's config).
|
|
|
|
An art pattern of `CONNECT` is set telling the system to look for `CONNECT<n>.*` where `<n>` represents a optional integer in art files to cause randomness, e.g. `CONNECT1.ANS`, `CONNECT2.ANS`, and so on. If desired, you can also be explicit by supplying a full filename with an extention such as `CONNECT.ANS`.
|
|
|
|
The entry `next` sets up the next menu, by name, in the stack (`matrix`) that we'll go to after `telnetConnected`.
|
|
|
|
Finally, an `options` object may contain various common options for menus. In this case, `nextTimeout` tells the system to proceed to the `next` entry automatically after 1500ms.
|
|
|
|
Now let's look at `matrix`, the `next` entry from `telnetConnected`:
|
|
|
|
```hjson
|
|
matrix: {
|
|
art: matrix
|
|
desc: Login Matrix
|
|
form: {
|
|
0: {
|
|
VM: {
|
|
mci: {
|
|
VM1: {
|
|
submit: true
|
|
focus: true
|
|
items: [ "login", "apply", "log off" ]
|
|
argName: matrixSubmit
|
|
}
|
|
}
|
|
submit: {
|
|
*: [
|
|
{
|
|
value: { matrixSubmit: 0 }
|
|
action: @menu:login
|
|
}
|
|
{
|
|
value: { matrixSubmit: 1 },
|
|
action: @menu:newUserApplication
|
|
}
|
|
{
|
|
value: { matrixSubmit: 2 },
|
|
action: @menu:logoff
|
|
}
|
|
]
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
In the above entry, you'll notice `form`. This defines a form(s) object. In this case, a single form
|
|
by ID of `0`. The system is then told to use a block only when the resulting art provides a `VM`
|
|
(*VerticalMenuView*) MCI entry. `VM1` is then setup to `submit` and start focused via `focus: true`
|
|
as well as have some menu entries ("login", "apply", ...) defined. We provide an `argName` for this
|
|
action as `matrixSubmit`.
|
|
|
|
The `submit` object tells the system to attempt to apply provided match entries from any view ID (`*`).
|
|
Upon submit, the first match will be executed. For example, if the user selects "login", the first entry
|
|
with a value of `{ matrixSubmit: 0 }` will match causing `action` of `@menu:login` to be executed (go
|
|
to `login` menu).
|
|
|
|
## ACS Checks
|
|
Menu modules can check user ACS in order to restrict areas and perform flow control. See [ACS](acs.md) for available ACS syntax.
|
|
|
|
### Menu Access
|
|
To restrict menu access add an `acs` key to `config`. Example:
|
|
```
|
|
opOnlyMenu: {
|
|
desc: Ops Only!
|
|
config: {
|
|
acs: ID1
|
|
}
|
|
}
|
|
```
|
|
|
|
### Flow Control
|
|
The `next` member of a menu may be an array of objects containing an `acs` check as well as the destination. Depending on the current user's ACS, the system will pick the appropriate target. The last element in an array without an `acs` can be used as a catch all. Example:
|
|
```
|
|
login: {
|
|
desc: Logging In
|
|
next: [
|
|
{
|
|
// >= 2 calls else you get the full login
|
|
acs: NC2
|
|
next: loginSequenceLoginFlavorSelect
|
|
}
|
|
{
|
|
next: fullLoginSequenceLoginArt
|
|
}
|
|
]
|
|
}
|
|
``` |
