[0.6.0] - 2020-11-16

Changed

  • Elixir version housekeeping. Fixed a warning on Elixir 1.11 by adding :eex to :extra_applications. ChromicPDF now requires Elixir >= 1.10 for its use of Application.compile_env/3.
  • Dropped poolboy in favour of nimble_pool. This renders the max_overflow poolboy option without effect.
  • Made "online mode" the default. Chrome will resolve all URL references unless the global option offline: false is set.

Added

  • Added telemetry events for the PDF generation & PDF/A conversion.
  • "On Demand" mode allows to start & stop Chrome as needed, much like puppeteer does. This helps in development to prevent leaving behind zombie processes when the BEAM is aborted with Ctrl+C.
  • New global option discard_stderr allows to enable Chrome's stderr logging which is by default piped to /dev/null.

Fixed

  • Graceful shutdown is now actually graceful in that it waits for Chrome to clean up the debugging sessions and close the pipe on its end.

[0.5.2] - 2020-07-17

Fixed

  • Moved static files required for PDF/A generation to /priv so they are embedded into releases.
  • Moved logo files out of /priv so they are not included in releases.

[0.5.1] - 2020-07-10

Fixed

  • Fixed typespecs for Template.source_and_options/1. [content_option] weren't allowed as call to styles/1 narrowed type to [style_option].
  • Added missing keys to style_option.

[0.5.0] - 2020-07-10

Changed

  • Removed the :width and :height options from Template.styles/1 and Template.source_and_options/1 as it turns out that Chrome does not pay attention to @page dimensions and instead still sets the size of the produced PDF to US letter. Since it does not seem possible to the PDF size in Chrome headless besides using the paperWidth and paperHeight options, moved to a :size option instead that accepts names like :a4, :us_letter, and tuples of {<width>, <height>} in inches. These are then passed to paperWidth and paperHeight.
  • Ditched the preferCssPageSize option from Template.source_and_options/1 as it did not seem to have any effect. See above.

Added

  • Added zoom: 0.75 to both #header and #footer in the template as this seems to be exactly what is needed to reverse the viewport scaling that Chrome uses on them by default. With this, headers & footers and the content can use the same CSS styles.
  • Included -webkit-print-color-adjust: exact rule to template so background-color rules are enabled by default.

Fixed

  • Make print_to_pdfa/2 actually accept source_and_options() map from Template.

[0.4.0] - 2020-07-09

Added

  • Allow {:url, <path>} input tuples where path is only a path, and not a file:// URL.

Changed

  • When passing a function to the :output parameter, the function result will now be returned as part of the print_to_pdf & friends result as {:ok, <callback_result>} instead of :ok.

[0.3.1] - 2020-04-09

Added

  • Handle {:safe, iolist()} tuples in API and Template (for content coming from Phoenix.View). Expose Template.html_concat as potentially useful helper.
  • Reset navigation history after each print job to avoid leaking information.
  • Create new empty browser context for each target (similar to incognito tab).
  • Restart browser target after a maximum number of PDFs have been printed to avoid memory bloat.

Changed

  • Set user agent to custom string.
  • Default number of sessions in pool to half the number of available cores.

[0.3.0] - 2020-03-30

Added

  • HTML source and header and footer template accept iolists now
  • New Template module contains basic CSS skeleton to easily dimension & layout pages (header & footer margins)

[0.2.0] - 2020-03-06

Added

  • Add set_cookie option to print_to_pdf/2.
  • Targets now navigate to about:blank after PDF prints.
  • Fixed the temporary file yielding way of calling print_to_pdf/2.

[0.1.0] - 2020-03-02

Added

  • First release to hex.pm
