Changes in version 0.3.0 (2026-05-01)                  

New Features

  - When the size of the terminal changes new plots (e.g. when calling
    implicitly or explicitly new.plot) will rescale to follow the size
    of the new terminal. This happens only when the width and height of
    the plot were not explicitly set. Note that after resizing the
    terminal updates to a new plot will not resize the plot.

Bug fixes

  - Support for Terminal Graphics Protocol and Sixel was not properly
    detected in Vim and NVim terminals. In NVim this even caused the
    terminal to hang. Code now checks if it is running in such a
    terminal. Graphics output is not supported in these terminals, but
    at least now this is detected properly.

  - Sixel support is now detected when running in tmux for terminals
    that support sixel.

  - term_palette() no longer gives an error and returns the default
    palette, when run in kitty with remote control disabled.

                 Changes in version 0.2.1 (2025-11-26)                  

Bug fixes

  - Opening a sixel or tgp device generated an error when either raster
    or ragg (version <= 1.5.0) is installed.

                 Changes in version 0.2.0 (2025-11-25)                  

New features

  - Adds support for the terminal graphics protocol (tgp) when used
    within tmux. Leveraging this feature requires that tmux is
    configured with allow-passthrough on. (@dgkf, #9)

  - Fixes the labelling of values in term_dim(), which previously had
    columns and rows names swapped. (@dgkf, #9)

  - Add options term_background, term_foreground and term_palette to set
    the background and foreground colour of the terminal. Currently
    these are only detected automatically in kitty. With these options
    it is possible to set these manually for other terminals. Note that
    in order to automatically use these in new devices, either the
    argument term_col = TRUE of tgp() or sixel(). or the option term_col
    = TRUE needs to be set. (#8)

  - Add support for quering colour mode (dark/light) for terminals that
    support this. When term_col = TRUE, different default colours are
    used for dark and light mode. When the terminal does not support
    this, the colours of light mode are used. (@dgkf, #11)

  - New is_ghostty() function to determine if we are running in ghostty.

Bug fixes

  - The package now uses the new feature of ragg (>1.5.0) where it is
    possible to query the ragg device if it has changed
    (https://github.com/r-lib/ragg/issues/204). This has the advantage
    that it is much less resource intensive to detect changes.
    Previously changes were detected by comparing the raster pixel by
    pixel to the previous raster. It is also more reliable. For example
    when a plot command does not change the device, the device
    previously also didn't update, which could be confusing. Note that
    at the moment of release of this version of terminalgraphics this
    feature is not yet available in the version of ragg currently on
    CRAN.

  - Determination of DPI of output handles missing resolution.
