Fixes#4. `shr` uses `libxml-parse-html-region` internally which converts all
tags and attributes to lowercase when constructing the DOM since HTML is
case-insensitive. But SVG uses XML which is a case-sensitive language. This
means that a conversion from the DOM back to an XML representation does not
restore the case of tags/attributes if `libxml-parse-html-region` is used. This
is solved by using `libxml-parse-xml-region` which preserves case.
* jupyter-repl.el (jupyter-repl-put-image): New function.
(jupyter-repl-insert-html): Temporarily bind libxml-parse-html-region to
libxml-parse-xml-region. Temporarily bind shr-put-image-function to
jupyter-repl-put-image.
`jupyter-channels.el` depends on the `jupyter-send` method defined in
`jupyter-messages.el` whereas `jupyter-messages.el` does not depend on any
functions in `jupyter-channels.el`.
* jupyter-channel.el: Require `jupyter-messages`
* jupyter-messages.el: Remove `jupyter-channels` require
Previously pending requests were associated with the ioloop process itself, but
pending requests are a particular feature of the client and used only for a
client's purpose.
* If `comment-start` is nil, using a regular expression with an empty or clause
causes an infinite loop. Ensure that we only add the or clause when
`comment-start` is non-nil in `jupyter-repl-propertize-output`.
* Copy over the `comment-start` from the REPL language buffer in
`jupyter-repl-initialize-fontification`
* Rename `jupyter-repl-output-buffer-marker` to `jupyter-output-buffer-marker`
* Rename `jupyter-repl-output-buffer-last-request-id` to
`jupyter-output-buffer-request-id`
* Add `jupyter--reset-output-buffer-p` which returns non-nil if the current
input buffer should be reset.
* Simplify the `jupyter-with-output-buffer` macro
* Rename `jupyter-repl-with-output-buffer` to `jupyter-with-output-buffer`.
* Replace uses of `jupyter-repl-with-doc-buffer` with
`jupyter-with-output-buffer`. The difference between the two was that
`jupyter-repl-with-doc-buffer` always reset the buffer before inserting new
output.
* Add `jupyter-channel--reset-socket` which does the work of connecting the
heartbeat channel to its endpoint and takes care of possibly reseting the
socket after sending a ping.
