matterhorn v50200.11.0 Release Notes

Release Date: 2020-10-15 // over 3 years ago

  • 🆕 New features:

    • Matterhorn now opens post links itself rather than invoking the configured URL open command. This means that if a user obtains a link to a post in the web client and pastes it into a message, Matterhorn will detect it, and if the user chooses to open that link, Matterhorn will switch to the post's channel and show the post. This change comes a new theme attribute, permalink, that is used to style post permalinks. Post links with no labels appear as <post link>; post links with labels are rendered with their labels. Post links also appear in the URL list accessed with C-o, and they are opened by the message selection mode o binding.
    • Message timestamp visibility can now be controlled with the configuration setting showMessageTimestamps (default: True) and can be toggled at runtime with the new /toggle-message-timestamps command.
    • The channel list can now be displayed on either the left side of the screen or the right. This is controlled with a new configuration setting, channelListOrientation, set to either left (the default and previous behavior) or right.
    • Matterhorn now supports strikethrough syntax in messages. This change adds a new theme attribute, markdownStrikethrough, that is used to style strikethrough text. This change also adds support for strikethrough as a valid style specifier in theme customization files. Bear in mind that your terminal might not support strikethrough; for details, see the FAQ entry on strikethrough support.
    • Matterhorn now has improved handling for channel topics (headers) with multiple lines of text. Previously Matterhorn displayed all lines in a multi-line channel topic but replaced newlines with spaces. That resulted in broken layouts for multi-line topics where layout was important. Now it renders the topics as originally intended with user control over how multi-line topics are displayed in order to let the user control how the topic affects screen real estate use.
      • Added a new key event, toggle-expanded-channel-topics, to toggle whether channel topics show only their first line or all lines.
      • Added a new configuration setting, showExpandedChannelTopics, to set this behavior on startup (default: True).
      • Added a new command, /toggle-expanded-topics, and a new default keybinding, F3, to control this behavior at runtime.
    • Added a /topic command that opens an interactive topic editor when run with no arguments. The editor provides a live Markdown preview of the channel topic. As part of the UI for this feature, new theme attributes were added: button and button.focused for rendering unfocused and focused buttons, respectively.
    • Command autocompletion now queries the server for available commands and includes those in the command list. Server commands are also indicated as being provided by the server to help distinguish them from Matterhorn-specific commands.

    Other changes:

    • Channel selection mode (C-g) now displays entries more consistently with the normal channel sidebar, including:
      • Channel mention counts and visual styles
      • The previous channel sigil (<) and first-unread channel sigil (~)
      • Channel mute status ((m))
      • Unread status and visual style
    • When composing replies, Mattehorn now displays the threat root message of the thread being replied to, rather than the message the user selected for reply (#670). This is intended to be less surprising than the old behavior since showing the root post in the preview is consistent with the display of the post in the message list once it is posted, where the root post is shown above the reply.
    • Matterhorn no longer considers external program output to constitute an error, instead only reporting external program errors on non-zero exit status (#665).
    • Matterhorn now decorates all hyperlinks with angle brackets. This change is intended to get around issues caused when a hyperlink label has a style or color that prevents the normal hyperlink color from being used, thus concealing the fact that it is a link. This makes all links visible regardless of link label content. In particular, links labeled foo now get rendered as <foo>. Links with no labels also get decorated this way.
    • The total unread channel count is now included in the window title bar updates.
    • The total unread channel count is now included in the channel list header.
    • Long lines in code blocks with no syntax highlighting are now wrapped to improve readability.
    • Command autocompletion now sorts command completions to prefer prefix matches first.
    • Command autocomplete now makes only one request for the server command list per completion attempt.
    • There is now a new /shortcuts command to stand in for server-provided version which did nothing in Matterhorn.
    • Message selection mode now remains active when:
      • Opening message URLs (C-s/o),
      • Exiting the message view window (C-s/v), and
      • Exiting the emoji reaction list window (C-s/a).
    • The channel list now includes an unread indicator in the DM channel section header when any DM channels are unread.
    • The visual style for channel selection match text now includes the underline style.
    • All unknown websocket events are now logged rather than triggering messages to ask the user to report issues.

    🐛 Bug fixes:

    • The URL list (C-o) now has a fixed header when the channel in question is a DM channel.
    • The URL list no longer treats URLs with the same target but different labels as duplicates.
    • The message editor's multi-line toggle UI hint now looks up the active keybinding rather than hard-coding it.
    • The channel sidebar's unread logic was improved (#655).
