Hello.
Here is a piece of code that I am having issue. I'm trying to use React
to parse reactively a server output. I have the following event definition:
let event_starting_at str = React.E.fold begin fun accu chunk -> accu^chunk end str received_event in
let to_be_parsed_event_of_event, set_to_be_parsed_event_of_event = React.E.create () in
let to_be_parsed_event = React.E.switch (event_starting_at "")
to_be_parsed_event_of_event in
let reinitialise_with unparsed_text = set_to_be_parsed_event_of_event
(event_starting_at unparsed_text) in
String chunks from the server are received by the 'received_event'
event, on the first line.
My issue is that the 'reinitialise_with' function is called in a
function 'phi' which is used in the following way:
let message_event = React.E.map phi to_be_parsed_event.
phi is the parsing function, so I'm not reproducing it directly here.
However, you would have the behaviour described further below with the
following code:
let phi string_chunk =
let new_string_chunk = String.copy string_chunk in
reinitialise_with new_string_chunk;
new_string_chunk
This creates hiccups in the events.
For example, at different time intervals, with to_be_parsed_event, I get:
q
qqw
qqwwe
qqwweer
qqwweerrt
etc... where I'd like in fact to have
q
qw
qwe
qwer
qwert
Advice would be appreciated on how to correct this.
All the best,
