v0.16.0

Breaking changes

• Sixel is now supported in all platform and enabled by default. The will break any build scripts that enable the sixel feature flag since that is now gone. Any maintainer that is building the package and enabling that flag should no longer do so (#828).

New features

• Allow executing snippets inside a PTY. This allows you to run tools that move the cursor around and redraw the terminal inside a slide (e.g. top, htop, etc). (#781) (#794) (#809) (#788) (#808) (#807) (#789).
• Use icy_sixel crate instead of sixel-rs. icy_sixel is a pure rust crate which simplifies code distribution and allows enabling sixel support by default (#818) - thanks @gcavelier.
• Add support for user comments in presentation rendering (#773).
• Allow passing in a mermaid config file (#833).
• Allow specifying mmdc puppeteer config path (#830) (#842).

v0.15.1

Fixes

• Disable OSC 11 when running in tmux (#696).
• Follow custom theme symlinks (#692).

v0.15.0

Breaking changes

• The behavior for "jump next fast" and "jump previous fast" keybindings (defaults to n and p) now jumps straight from one slide to the next/previous one ignoring pauses. Before this used to "reveal" all pauses when jumping forward before going to the next slide. This behavior was weird and unintuitive so now fast jumps go straight into the next/previous slides. The action of "showing all pauses on the current slide" can now be done by pressing s (#678).

New features

• Allow specifying where a snippet's execution output will go (#658).
• Add include comment command to import markdown files (#651) (#683).
• Allow validating snippets without explicitly executing them by using --validate-snippets switch (#645) (#637).
• Support iterm2 image protocol when running in tmux (#661).
• Add support for d2 diagrams (#657).
• Errors encountered when parsing markdown now always display the file, line, and column where the error was found, as well as the markdown line that caused the error (#674) (#653) (#684) (#685).
• Superscript via ^this^ and <sup>this</sup> syntaxes is supported when using the kitty terminal. For other terminals we try to use unicode half block characters which cover a portion of the ASCII charset. (#606)(#617 ) (#665).
• Allow alternative snippet executors for languages that support execution. This allows, for example, runnig rust code via rust-script or python code via pytest (#614).
• Allow using env var PRESENTERM_CONFIG_FILE to point to the config file (#663) - thanks @Silver-Golden.
• Set background color via OSC 11 to avoid having a colored edge around the presentation (#623) (#624) (#627).
• Add support for markdown footnotes (#616).
• Runtime errors are now centered rather than being left aligned with some fixed margin (#638).
• Allow configuring number of newlines in between list items (#628).
• Allow 3 digit hex colors (#609) - thanks @peterc-s.
• Allow configuring font used in PDF export (#608).
• Added uv as an alternative executor for python code (#662) - thanks @JanNeuendorf.
• Allow multiline slide titles (#679).
• Add support for multiline slide titles (#682) - thanks @barr-israel.
• Add support for multiline subtitle (#680) - thanks @barr-israel.
• Add support for syntax highlighting and execution for F# (#650) - thanks @mnebes.
• Use text style/colors in rust-script errors (#644).
• Added rust-script-pedantic alternative executor for rust (#640).

Fixes

• Skip speaker notes slide on skip_slide (#625).
• Don't loop on 0 bytes read when querying capabilities (#620).
• Make code snippet language specifiers case insensitive (#613) - thanks @peterc-s.
• Bump dependencies (#681) - thanks @barr-israel.

Chore

• Refactored code to make it more easily testeable, and added lots of tests to ensure markdown is rendered as expected. This will hopefully reduce the number of errors found after each release (#660) (#659) (#655) (#647).
• Bump rust version to 1.82 (#611).
• Perform better validation around matching HTML tags (#668).
• Don't run nightly job if the git hash hasn't changed (#667) (#675) (#669).
• Display an error when using http(s) urls in image tags (#666).
• Update Catppuccin themes to use palettes (#672) - thanks @jmcharter.

v0.14.0

New features

• Add support for exporting presentations as HTML files (#566) (#595) (#575) (#599) - thanks @JustSimplyKyle.
• Snippet execution output now contains configurable padding and built-in themes default to the same padding as snippets (2 spaces horizontally, one line vertically) (#592) (#593).
• Add highlighting and execution support for Jsonnet (#585) - thanks @imobachgs.
• Allow configuring snippets to be executed sequentially during exports (#584).

Fixes

• Skip slides with pauses correctly (#598).
• Avoid printing text if there's no vertical space for it, which otherwise looks bad particularly when using font size > 1 (#594).
• Execute snippets only once during export (#583).
• Don't add an extra pause after lists if there's nothing left (#580).
• Allow interleaved spans and variables in footer (#577).
• Truly center +exec_replace snippet output (#572).

Docs

• Added link to public presentation using presenterm (#589) - thanks @pwnwriter.
• Rename parameter name to the correct one in docs (#570) - thanks @DzuWe.
• Fix typo in highlighting.md (#586) - thanks @0atman.

Chore

• Bump dependencies (#596).

v0.13.0

Breaking changes

• The CLI parameter to generate the JSON schema for the config file (--generate-config-file-schema) is now hidden behind a json-schema feature flag. The JSON schema file for the latest version is already publicly available at https://github.com/mfontanini/presenterm/blob/${VERSION}/config-file-schema.json, so anyone can use it without having to generate it by hand. This allows cutting down the number of dependencies in this project quite a bit (#563).

New features

• Support for slide transitions is now available (#530):
  • Add fade slide transition (#534).
  • Add slide horizontally slide transition animation (#528).
  • Add collapse_horizontal slide transition (#560).
• Add --output option to specify the path where the output file is written to during an export (#526) - thanks @marianozunino.
• Allow specifying start/end lines in file snippet type (#565).
• Allow letting pauses become new slides when exporting (#557).
• Allow using images on right in footer (#554).
• Add max_rows configuration to cap vertical size (#531).
• Add julia language highlighting and execution support (#561).

Fixes

• Center overflow lines when using centered text (#546).
• Don't add extra space before heading if prefix in theme is empty (#542).
• Use no typst background in terminal-* built in themes (#535).
• Use std::env::temp_dir in the external_snippet test (#533) - thanks @Medovi.
• Respect extends in a theme set via path in front matter (#532).

Misc

• Refactor async renders (e.g. mermaid/typst/latex +render blocks, +exec blocks, etc) to work truly asynchronously. This causes the output to be polled faster, and causes jumping to a slide that contains an async render to take a likely negligible (but maybe noticeable) amount of time to be jumped to. This was needed for slide transitions to work seemlessly (#556).
• Get rid of textproperties (#529).
• Add links to presentations using presenterm (#544) - thanks @orhun.

Performance improvements

• A few performance improvements had to be done for slide transitions to work seemlessly:
  • Pre-scale ASCII images when transitions are enabled (#550).
  • Pre-scale generated images (#553).
  • Cache resized ASCII images (#547).

v0.12.0

Breaking changes

• Using incremental lists now adds an extra pause before and after a list. Use the defaults.incremental_lists configuration parameter to go back to the previous behavior (#487) (#498).

New features

• PDF exports are now generated by invoking weasyprint rather than by using the now deprecated presenterm-export. This gets rid of the need for tmux and opens up the door for other export formats (#509) (#517).
• PDF export dimensions can now also be specified in the config file rather than always having them inferred by the terminal size (#511).
• Allow specifying path for temporary files generated during presentation export (#518).
• Respect font sizes in generated PDF (#510).
• Add skip_slide comment command to avoid including a slide in the final presentation (#505).
• Add alignment comment command to specify text alignment for the remainder of a slide (#493) (#522).
• Add --current-theme CLI parameter to display the theme being used (#489).
• Add gruvbox dark theme (#483) - thanks @ret2src.

Fixes

• Fix broken ANSI escape code parsing which would cause command output to sometimes be incorrectly parsed and therefore led to its colors/attributes not being respected (#500).
• Center lists correctly (#512) (#520).
• Respect end slide shorthand in speaker notes mode (#494).
• Use more visible colors in snippet execution output in terminal-light/dark themes (#485).
• Show error if sixel mode is selected but disabled (#525).

CI

• Add nightly build job (#496).

Docs

• Fix typo in README.md (#490) - thanks @eltociear.
• Correctly include layout pic (#495) - thanks @Tuxified.

Misc

• Cleanup text attributes (#519).
• Refactor snippet processing (#484).

v0.11.0

Breaking changes

• Footer templates are now sanitized, and any variables surrounded in braces that aren't supported (e.g. {potato}) will now cause presenterm to display an error. If you'd like to use braces in contexts where you're not trying to reference a variable you can use double braces, e.g. live at {{PotatoConf}} (#442) (#467) (#469) (#471).

New features

• Add support for kitty's font size protocol. This is now used by default in built in themes in a few components such as the intro slide's title and slide titles. See the example presentation gif to check out how this looks like. Terminal suport for this feature is detected on startup and will be ignored if unsupported. This requires kitty >= 0.40.0 (#438) (#460) (#470).
• Allow specifying font size in a comment command, which causes any subsequent text in a slide to use the specified font size. Just like the above, only supported in kitty >= 0.40.0 for now (#458).
• Footers can now contain images in the left and center components. This allows including some form of branding/company logo to your presentations (#450) (#476).
• Footers can now contain inline markdown, which allows using bold, italics, <span> tags for colors, etc (#466).
• Presentation titles can now contain inline markdown (#464).
• Introduce palette.classes in themes to allow specifying combinations of foreground/background colors that can be referenced via the class attribute in <span> tags (#468).
• It's now possible to configure the alignment to use when max_columns is configured and the terminal width is larger than it (#475).
• Add support for wikilinks (#448).

Fixes

• Don't get stuck if tmux doesn't passthrough (#456).
• Don't squash image if terminal's font aspect ratio is not 2:1 (#446).
• Fail if --config-file points to non existent file (#474).
• Use right script name for kotlin files when executing (#462).
• Respect lists that start at non 1 indexes (#459).
• Jump to right slide on code attribute change (#478).

Improvements

• Remove result return type from builder fns that don't need it (#465).
• Refactor theme code (#463).
• Restructure terminal code and add test for margins/layouts (#443).
• Use fastrand instead of rand (#441).
• Avoid cloning strings when styling them (#440).

v0.10.1

Fixes

• Don't error out if options in front matter doesn't include auto_render_languages (#454).
• Bump sixel-rs to 0.4.1 to fix build in aarch64 and riscv64 (#452) - thanks @Xeonacid.
