v0.0.7 2024-09-09 Zagreb

• Add support for wasm_of_ocaml. Thanks to Jérôme Vouillon for the patchset (#51).
• Deprecate Tarray.{get,set}. These function become less efficient in order to support wasm_of_ocaml. Use Tarray.to_bigarray1 to convert to a bigarray and operate on that instead (#51).
• Fix Jstr.pad_{start,end} specifying the [pad] optional argument was being ignored. Thanks to Valentin Gatien-Baron for noticing.
• Add Jv.is_array a binding to Array.isArray which is the recommended way to test a value for an array. Thanks to Valentin Gatien-Baron for the patch (#59).
• Fix Brr_webaudio.Audio.Node.Media_element_source.create the MediaElementAudioSourceNode property was mispelled. Thanks to Emile Trotignon for the report and the patch (#57).
• Fix Fut.tick in the presence of effects compilation.
• Add At.download attribute constructor.
• Fix At.draggable. It is enumerated not a boolean attribute. Thanks to Ulysse for the patch (#55).
• At.class' attribute values. Allow to specify multiple classes in a single At.t value. This was not possible before which is surprising. Thanks to Basile Clément for noticing and patching (#53).

v0.0.6 2023-07-29 Zagreb

• The experimental library brr.note has been migrated to the note.brr library available via the note package. The toplevel modules were renamed from Brr_note* to Note_brr*.

• Fix encoding mess in Brr.Uri which tried to expose a model that is not workable in practice due to the way the URI standard is defined.

  • Accessors and Uri.with_uri no longer perform percent decoding and encoding for you.
  • Added helper functions Uri.[with_]{query,fragment}_params.
  • Added helper functions Uri.[with_]{path_segments}.

  Thanks to Max Lang for the report and making sure the new API makes sense (#50).

• Add canvas color space support (note: unsupported on Firefox for now).

  • C2d.attrs, add color_space and will_read_frequently attributes.
  • Add C2d.Image_data.color_space and a ?color_space optional argument to C2d.{create,get}_image_data and C2d.Image_data.create.

• Brr.Blob.{array_buffer,text,data_uri}: add an optional argument ?progress. If provided the load happens via a FileReader object and load progress is reported (#39).

• Updated developer tool console to Manifest V3 (#44).

v0.0.5 2023-05-10 La Forclaz (VS)

• Add Brr_webgpu, bindings for WebGPU. Supported by a grant from the OCaml Software Foundation.
• Brr.El.scroll_into_view, make align_v align according to specification (did the exact converse).
• Brr_io.Fetch.cache becomes a function taking unit. It seems accessing it at initalisation time trips the (latest ?) Firefox WebWorkers.
• Make the Brr_canvas.Gl module initialisation bits safe when there is no WebGLRenderingContext. Thanks to Haochen Kotoi-Xie for reporting.

v0.0.4 2022-12-05 Zagreb

Changes for upcoming js_of_ocaml effect support

The following changes are needed for the upcoming effect support in js_of_ocaml. Thanks to Jérôme Vouillon for his help.

• Important Add Jv.callback. When the effect support lands it will no longer be possible to invoke an OCaml function f from JavaScript by simply using (Jv.repr f) to get a Jv.t value as was suggested in the cookbook. You have to use (Jv.callback ~arity f) with arity the arity of the function. The recipes of the cookbook to deal with callbacks and exposing OCaml functions to JavaScript have been updated accordingly.
• Brr.Ev.listen no longer returns unit but an abstract value of type Brr.Ev.listener. If you don't need to unlisten you can simply ignore that value. If you do, see next point.
• Brr.Ev.unlisten is changed to take a value of type Brr.Ev.listener. Previously you had to invoke it with the same arguments you gave to Brr.Ev.listen like in JavaScript.

Additions

• Add Brr_webmidi, bindings for Web MIDI.
• Brr.At, add support for accesskey, action, autocomplete, autofocus, list, method, selected, style attributes. Make sure MDN doc links do not 404.
• Add Brr.At.float.
• Add Brr.At.{void,is_void,if',if_some} and deprecate Brr.At.{add_if,add_if_some}. The new scheme if more convenient and clearer when working with list literals.
• Add Brr.File.relative_path.
• Add Brr_canvas.{C2d,Gl}.get_context and deprecate Brr_canvas.{C2d,Gl}.create whose names are misleading (#36).
• Add Brr_canvas.C2d.{set_transform',transform'} taking matrix components directly.
• Add Jstr.binary_{of,to}_octets to convert between OCaml strings as sequence of bytes and JavaScript binary strings (#18 again)

Breaking changes

• Brr.El.v, perform At.style attribute merging like we do with At.class. This is a breaking change if you had El.v calls with multiple style attributes definition and expected the last one to take over. Note that the At.style value is introduced in this version.

Bug fixes and internal changes

• Fix Brr_canvas.C2d.transform it was binding to resetTransform instead of transform (#38).
• Adapt to js_of_ocaml-toplevel changes.
• Make the modules' initialisation bits web worker safe. We had toplevel code that accessed properties of values that are not allowed in workers (e.g. Brr.El accessing document or Brr_note accessing mutation observers). These modules may still be linked in your web worker code (e.g. if you fork()-like your workers) in which case these toplevel initialisation bits would get executed and fail.

v0.0.3 2022-01-30 La Forclaz (VS)

• Require js_of_ocaml 4.0.0:

  • Allows brr, js_of_ocaml, and gen_js_api bindings to be used in the same program.
  • Adding -no-check-prims during bytecode linking is no longer required.

  Thanks to Hugo Heuzard for making the ground work in js_of_ocaml and providing a patch (#2, #33).

• Add Brr.Ev.beforeunload.

• Add Brr.Ev.Pointer.as_mouse.

• Tweak Brr.Ev.{Drag,Wheel}.as_mouse_event into Brr.Ev.{Drag,Wheel}.as_mouse to avoid coercion madness.

• Add Brr.El.{previous,next}_sibling.

• Add Brr.El.remove_inline_style.

• Add Brr.El.Style.{top,left,right,bottom,position,z_index}.

• Fix Blob.of_jstr. It was not working. Thanks to Kiran Gopinathan for the report (#31).

• Ev.target_{of,to}_jv take and return a Jv.t value instead of an 'a. Thanks to Joseph Price for the report (#28).

v0.0.2 2021-09-23 Zagreb

• Change the Brr.Base64 module (atob, bota) to make it more useful and less error prone (#18). Thanks to Armaël Guéneau for shooting himself in the foot.
• Add Brr.Window.open' (#20). Thanks to Boris Dob for the suggestion and the patch.
• Rename Brr_webcrypto.Crypto_algo.rsassa_pks1_v1_5 to rsassa_pkcs1_v1_5. Thanks to Hannes Mehnert for the report and the fix.
• Add Brr.El.parent (#10). Thanks to Sébastien Dailly for the suggestion and the patch.
• Add Brr.El.{find_first_by_selector,fold_find_by_selector} to lookup elements by CSS selectors.
• Jstr.{starts_with,ends_with}, change labels to follow Stdlib labelling.
• Add optional base argument to Brr.Uri.{v,of_jstr}.
• Add Brr.Uri.Params.is_empty.
• Add Brr_io.Form.Data.{is_empty,has_file_entry,of_uri_params,to_uri_params}.
• Tweak interfaces of Brr_canvas.Image_data.create, Brr_webaudio.Node.connect_node, Brr_webaudio.Node.connect_param to not trigger the 4.12 definition of the warning unerasable-optional-argument.
• Fix for uncaught JavaScript exceptions in the OCaml console (#21). The fix is brittle, the right fix is to solve (#2).
• Fix Brr_canvas.Gl for browsers that do not support GL2 contexts. On these browsers this would lead to obscure failures in separate compilation mode. Thanks to Duncan Holm for the report (#9).
• Fix wrong value of Request.Credentials.include.
• Fix Blob.of_array_buffer (#23). Didn't work at all. Thanks to Armaël Guéneau for the report and the fix.
• Fix Jstr.concat when sep is unspecified (#14). Thanks to Sébastien Dailly for the report.
• Fix signature of Brr_webcrypto.Subtle_crypto.{export,import}_key. Thanks to Romain Calascibetta for the report and the fix.
