Terminalogue 0.5.1

Changelog

All notable changes to the Terminalogue VS Code extension are documented here.

0.5.1

Changed

• The powershell theme is 20% darker: every colour in its palette dimmed to 80% of its
  previous value, with hue and saturation untouched, so it is the same console with the
  brightness turned down rather than a different palette.

Notes

• Contrast was re-checked after the change and every pair still clears WCAG AA comfortably:
  terminal text 8.96:1, the window title and controls 5.80:1, the selected speed 6.13:1 and
  the diagnostics box 5.87:1, with the focus outline at 5.18:1 and the cursor at 8.96:1
  against the 3:1 non-text threshold.
• Presentation only, and only for powershell: no other theme changed, and nothing about the
  DSL, the controls, playback or the security model did either.

0.5.0

Added

• @size <columns>x<rows> — a fixed terminal viewport, e.g. @size 80x24. The size applies
  to the terminal body: the title bar and the controls are not counted in the rows.
• The area is reserved from the first render, so a block no longer grows as it plays and
  nothing under it moves. @clear, Pause, Restart and every playback speed keep it.
• Output taller than the rows scrolls inside the terminal, following the newest line while
  a block is playing.
• Diagnostics for a malformed size, a size outside the supported range (columns 20–240,
  rows 5–100) and a duplicate @size in one block.

Notes

• A block with no @size is sized automatically, exactly as every block was before this
  release. Documents written for 0.1 through 0.4 render identically.
• @size is presentation metadata for the whole block: it changes no prompt, no command,
  no timing and no playback behaviour, and there is no way to resize a terminal part-way
  through one. All five themes share the same terminal metrics, so a size means the same
  thing in each of them.
• The terminal never grows wider than the preview pane. Long lines keep the wrapping they
  have always had; the font is not scaled to fit the columns.

0.4.0

Terminalogue gained a third host in this release: termlogue blocks now animate inside
Marp HTML presentations, through a new @terminalogue/marp package and a companion
Obsidian plugin, Terminalogue Presenter.

Notes

• The VS Code extension itself is unchanged. It is versioned in lockstep with the shared
  parser, renderer and stylesheet, which gained no new behaviour either: Marp reuses them
  exactly as this extension does, which is the whole point of the release.
• Nothing about the DSL, the themes, the controls or the security model changed. A block
  written for 0.1, 0.2 or 0.3 renders identically.

0.3.0

Added

• @theme — five built-in themes: light, dark, ubuntu, powershell and cmd.
  Theme names are matched case-insensitively.
• The powershell and cmd themes wear a console mark (>_ and C:\) in the title bar
  instead of the three window dots. It is drawn in CSS, with no image or vendor logo.
• Diagnostics for an unknown theme name and for a duplicate @theme in one block.

Notes

• A theme is presentation only: it changes no prompt, no command, no timing and no playback
  behaviour.
• A block with no @theme renders as dark, which is exactly how every block looked
  before this release. Documents written for 0.1 and 0.2 are unchanged.

0.2.0

Added

• @type — types text onto the end of the line already on screen, for answering an
  interactive question such as Proceed? [y/N].
• @pause — a playback breakpoint with an optional label, shown in the title bar while it
  holds playback.
• Copy commands — copies the block's $ command lines to the clipboard, and nothing
  else.
• A playback speed selector: 1× / 2× / 4× / Instant. Instant skips time, not control
  flow, so @pause still stops playback.

0.1.0

Initial release: termlogue fenced code blocks rendered into the built-in Markdown preview
as an animated terminal session, with $ command, terminal output, @title, @prompt,
@wait, @speed and @clear, Play / Pause / Restart controls, autoplay when a block
first scrolls into view, prefers-reduced-motion support and parse diagnostics rendered
inside the block.
