Mudlet 3.5.0

VadiVadi Member Posts: 67 ✭✭

It's autumn, we're back from summer vacation and have been adding more features into Mudlet for you!

New website!

Completely redesigned, is now a brand new website. As we'd love for more people to get into MUD gaming, having a modern website is a necessary foundation for that. Go check it out, we'd love to hear your feedback. Big thanks to itsTheFae and vadi2 for the work!

Copy/paste aliases/triggers/etc

You can now duplicate in your own profile, or across profiles, with copy/paste as you'd expect to:

Credits to dicene and vadi2 for making this happen!

Toggle search buttons with Alt+L

With the toolbar enabled:

You can now use Alt+L or Toolbox > Compact input line:

Deregister events

You can now deregister event handlers created with registerAnonymousEventHandler() using killAnonymousEventHandler() - or even just register temporary event handlers that expire after matching a certain condition. Big thanks to keneanung for adding this feature!

Use functions & lambdas more

registerAnonymousEventHandler(), tempTrigger(), tempColorTrigger(), tempLineTrigger(), tempComplexRegexTrigger(), tempRegexTrigger(), tempBeginOfLineTrigger(), and tempExactMatchTrigger() now all can accept Lua functions in addition to code in [[]]'s after the efforts of keneanung and vadi2. Compare the target highlight trigger how you had to write before:

Mudlet target trigger using

With how you can write it now:

Mudlet target trigger using function

For a start, you don't have to get lost in the sea of [[]]'s and syntax highlighting works fine. You can also pass the function name as-is:

registerAnonymousEventHandler("gmcp.Char.Items.Update", inventoryUpdate)

This is handy in a whole lot of cases - you no longer have you expose your internal functions publicly if you'd like them to trigger on something; this advanced example is now possible:

local name = "Bob"
local function example()
  print("Name variable is: "
tempTrigger("some text", example)

Having the local keyword in here was not something previously possible.

Search crash fixed

A pretty seldom one, but one that would happen nonetheless - Mudlet could crash when you searched for something in the buffer. This one was pretty hard to track down, but we believe we've found it - so if you've ever had it happen, upgrade!

Double prompt logging fixed

Built-in logging would be logging the prompt twice - that's been fixed now, and logging works as expected.

Editor bug notifications

When you had a bug in your code, fixed it, and saved - the notification wouldn't always go away. The bug in the code bugs notification has been squashed! Thanks to vadi2 for digging into this, logging, and the search crash.

Windows preview builds

A lot of work goes behind the scenes to make Mudlet better. Thanks to keneanung's efforts, we now can do preview builds for Windows in addition to the existing macOS and Linux builds. Helping us test new features is one way you could help Mudlet improve and now you can test from any computer!

We could use your help

Have you been using Mudlet for a while? We could use your help in several areas.

macOS users! We have to pay money rid of this thing:

Windows requires similar:

We don't charge for Mudlet, so you can see an obvious problem there - a code signing certificate over a hundred bucks a year. Help us out, visit the contributing page.

Code-wise, Mudlet is participating in Hacktoberfest - help contribute to the open project and get a limited edition T-shirt!

We're also looking at revamping our Windows installer so it's not a series of "next next next" buttons to be as streamlined as possible - as part of this, we're looking for an install animation to play while things are getting setup. If you've got skills this area, help us out!

    How much precisely is a signing license?

    Since this is a usermode program, you only need a Standard Signing Cert on Windows, not an EV cert. That runs in the $80-$150 USD per year range depending on vendor and length of cert validity.

    For Mac, you need a $99 USD Developer account.

    No matter what I do mudlet won't load one of my modules and now my UI doesn't work D:

    Edit: So apparently if you have auto-sync on for modules, and the client crashes, it can overwrite stuff and cause loss of data \o/

    ... Kind of happy I keep my system in VCS

    Sorry to hear that. Let us known the details over here, happy to have a look.

    I think maybe you meant to link somewheres else?  In any case the damage wasn't much more than the confusion and frustration until I realized what was happening since my system is version-controlled.  I should see if I can find out/replicate exactly what made it basically blank the file, though.

    It would not have been lost btw, Mudlet makes backups of the stuff in the moduleSync folder (for anything else reading this).
