* Removed terminal `cursor position reports` from most locations in the code. This should greatly increase the number of terminal programs that work with Enigma 1/2. For more information, see [Issue #222](https://github.com/NuSkooler/enigma-bbs/issues/222). This may also resolve other issues, such as [Issue #365](https://github.com/NuSkooler/enigma-bbs/issues/365), and [Issue #320](https://github.com/NuSkooler/enigma-bbs/issues/320). Anyone that previously had terminal incompatibilities please re-check and let us know!
|
||||
* Bumped up the minimum [Node.js](https://nodejs.org/en/) version to v14. This will allow more expressive Javascript programming syntax with ECMAScript 2020 to improve the development experience.
|
||||
* **New Waiting For Caller (WFC)** support via the `wfc.js` module.
|
||||
* Added new configuration options for `term.checkUtf8Encoding`, `term.checkAnsiHomePostion`, `term.cp437TermList`, and `term.utf8TermList`. More information on these options is available in [UPGRADE](UPGRADE.md).
|
||||
* Added new configuration options for `term.checkUtf8Encoding`, `term.checkAnsiHomePosition`, `term.cp437TermList`, and `term.utf8TermList`. More information on these options is available in [UPGRADE](UPGRADE.md).
|
||||
* Many new system statistics available via the StatLog such as current and average load, memory, etc.
|
||||
* Many new MCI codes: `MB`, `MF`, `LA`, `CL`, `UU`, `FT`, `DD`, `FB`, `DB`, `LC`, `LT`, `LD`, and more. See [MCI](./docs/art/mci.md).
|
||||
* SyncTERM style font support detection.
|
||||
* Added a system method to support setting the client encoding from menus, `@systemMethod:setClientEncoding`.
|
||||
* Many additional backward-compatible bug fixes since the first release of 0.0.12-beta. See the [project repository](https://github.com/NuSkooler/enigma-bbs) for more information.
|
||||
* Deprecated Gopher's `messageConferences` configuration key in favor of a easier to deal with `exposedConfAreas` allowing wildcards and exclusions. See [Gopher](./docs/servers/contentservers/gopher.md).
|
||||
* NNTP write (aka POST) access support for authenticated users over TLS.
|
||||
* [Advanced MCI formatting](./docs/art/mci.md#mci-formatting)
|
||||
|
||||
## 0.0.12-beta
|
||||
* The `master` branch has become mainline. What this means to users is `git pull` will always give you the latest and greatest. Make sure to read [Updating](./docs/admin/updating.md) and keep an eye on `WHATSNEW.md` (this file) and [UPGRADE](UPGRADE.md)!

### 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](https://docs.python.org/3/library/string.html#format-specification-mini-language).
|
||||
|
||||
#### MCI Formatting
|
||||
For more advanced layouts, you may want to apply formatting to MCI codes. In this case, an alternative syntax is supported similar to standard [Entry Formatting](#entry-formatting).
|
||||
|
||||
MCI codes can be surrounded by `{` and `}` in the `text` field in your `theme.hjson` for a Text Label (`%TL` aka [Text View](./views/text_view.md)). Some examples:
|
||||
```hjson
|
||||
text: "|00|07{BN!stylel33t}" // render board name in "l33t" text
|
||||
|
||||
// MCI codes that produce a number can use appropriate stylers as well
|
||||
text: "|00|07{SD:,}"
|
||||
// ...or perhaps
|
||||
text: "|00:07{SD!countWithAbbr}"
|

```

> :bulb: MCI formatting also applies when programmatically calling [setText()](https://github.com/NuSkooler/enigma-bbs/blob/6710bf8c084487be2ee1d46d72a05d17a7b166f4/core/text_view.js#L148) of [TextView's](./views/text_view.md) and derived views.

## Predefined Label View
|
||||
A predefined label view supports displaying a predefined MCI label on a screen.
|
||||
|
||||
## General Information
|
||||
|
||||
> :information_source: A predefined label view is defined with a percent (%) and the characters PL, followed by the view number and then the predefined MCI value in parenthesis. For example: `%PL1(VL)` to display the Version Label. *NOTE*: this is an alternate way of placing MCI codes, as the MCI can also be placed on the art page directly with the code. For example `%VL`. The difference between these is that the PL version can have additional formatting options applied to it.
|
||||
|
||||
> :information_source: See *Predefined Codes* in [MCI](../mci.md) for the list of available MCI codes.
|
||||
|
||||
> :information_source: See [MCI](../mci.md) for general information on how to use views and common configuration properties available for them.
|
||||
|
||||
### Properties
|
||||
|
||||
| Property | Description |
|
||||
|-------------|--------------|
|
||||
| `textStyle` | Sets the standard (non-focus) text style. See **Text Styles** in [MCI](../mci.md) |
|
||||
| `justify` | Sets the justification of the MCI value text. Options: left (default), right, center |
|
||||
| `fillChar` | Specifies a character to fill extra space in the view. Defaults to an empty space |
|
||||
| `width` | Specifies the width that the value should be displayed in (default 3) |
|
||||
| `textOverflow` | If the MCI is wider than width, set overflow characters. See **Text Overflow** below |
|
||||
|
||||
### Text Overflow
|
||||
|
||||
The `textOverflow` option is used to specify what happens when a predefined MCI string is too long to fit in the `width` defined.
|
||||
|
||||
> :information_source: If `textOverflow` is not specified at all, a predefined label view can become wider than the `width` if needed to display the MCI value.
|
||||
|
||||
> :information_source: Setting `textOverflow` to an empty string `textOverflow: ""` will cause the item to be truncated if necessary without any characters displayed
|
||||
|
||||
> :information_source: Otherwise, setting `textOverflow` to one or more characters will truncate the value if necessary and display those characters at the end. i.e. `textOverflow: ...`
