QUESTION
Inserting a "," in a particular position of a text
From question above, I have gotten errors because a text contained some full-width characters. I deal with some Japanese text data on RHEL server. Question above was a perfect solution for utf-8 text but the UNIX command wont work for Japanese text in SJIS format.
The difference between these two is that utf-8 counts every character as 1 byte and SJIS counts alphabets and numbers as 1 byte and other Japanese characters, such as あ, as 2 bytes. So the sed command only works for utf-8 when inserting ',' in some positions.
My input would be like
...ANSWER

is 3 bytes in UTF-8
Depending on the locale GNU sed supports unicode. So reset the locale before running sed
commands, and it will work on bytes.
And I would like to insert ',' after 3 bytes, 4 bytes and 3 bytes
Just use a backreference to remember the bytes.
QUESTION
My Activity is showing a RecyclerView
with a LinearLayoutManager
. I want to get the first item (View
) in the list. According this post's accepted answer , I can do it calling LinearLayoutManager.findViewByPosition()
method, but I'm getting null
instead. Why?
ANSWER
Answered 2017-Sep-20 at 16:14It's because the population of the RecyclerView
by the Adapter
is asynchronous.
You may launch an event when the adapter finish to populate the RecyclerView to be sure that findViewByPosition
returns something to you.
Detect when RecyclerView have finished to populate all visible items is a bit difficult, because we should calculate each item size (width and height) and define how many items can enter in current device display.
But if what you need is only to access first populated item then you can fire your event in your Adapter's onBindViewHolder
method, obviously inserting the needed controls to avoid to fire events for every added item.

produces a sequence of vectors, so the filter function must accept a single parameter:
(filter (fn [[a b]] (not= a b)) (map vector (seq [1 2 3]) (seq '(:a :b :c))))
But there is a better way:
(filter (partial apply not=) (map vector (seq [1 2 3]) (seq '(1 :b :c))))

...ANSWER
Answered 2018-Dec-12 at 17:39in Javascript the word class
is reserved meaning that inside your JSX code you cannot include that word because it is confused with the class
keyword of Javascript.
JSX code is not really Javascript and it is later compiled so that the javascript runtime understands it.
So, use className
instead of class
to set a CSS class of an element:
card data
becomes
card data

I have a stackblitz here - https://stackblitz.com/edit/d3-stacked-trend-bar-positioned-months-4sqvwd?embed=1&file=src/app/bar-chart.ts&hideNavigation=1
I'm using D3 to create a stacked bar chart in Angular
I now also need to have a line graph on the same chart.
I think the best way to do this is with a dual axis.
I have the second axis working but can't get the line to work.
Can anyone point me the direction to get this working
