kandi X-RAY | crochet Summary
Crochet is a tool for building bootable FreeBSD images. This tool was formerly known as "freebsd-beaglebone" or "beaglebsd" as the original work was done for BeagleBone. But it now supports more boards and should easily extend to support many more.

QUESTION
I am trying to run a scrapy script with splash
, as I want to scrape a javascript
based webpage, but with no results. When I execute this script with python command, I get this error: crochet._eventloop.TimeoutError
. In addition the print statement in parse method never printed, so I consider something is wrong with SplashRequest
. The code that I wrote in order to implement this is that:
ANSWER

befor running code.
If I run splash
(as docker
image) then I also get this error because it had different IP
but if I use correct IP
in 'SPLASH_URL'
then it works.
On Linux I got IP

I am running scrapy spider using flask and crochet. In this I am using Rule Link extractor for defining the rules. In the rule, I am setting allow_domains
which is passed from flask application.
spider.py
...ANSWER
Answered 2022-Feb-11 at 06:44The problem here is that CrawlSpider constructor (init) is also handling the rules parameter, so if we need to assign them, we'll have to do it before calling the default constructor.

I'm doing a Leaflet map with some GeoJSON data.
I try to add the cluster function to my JS file. As I added some filter and styling features according to properties, I'm unable to find the right way to code the cluster fonction.
Here is the GeoJSON layer and the filter verificator:

I've been trying to do this several days ago.
I want to make a query that gets all the businesses that are registered in one city, after that for each Business I'd like to get all products in business and finally store it onto a new object and send it as a response to front end.
This is the code I'm using:

QUESTION
Dearest,
This is similar to one script I have been running for months on my platform.
I have some long text inside a column (called "description") and I want to wrap it (no more than 20 characters per line). In order to do this, I have a function which inserts a break line "\n" in the text whenever needed. I then use kableextra's "linebreak" function on that text to make sure the linebreak is properly understood (and it is).
The final result is then processed via latex to generate a pdf. The trouble is that the text inside the description column, although broken as I want, is no longer left aligned. I am sure I have not had this in the past (before updating R to 4.0.3 and reinstalling kableextra).
Anyone who knows how to fix this will have my gratitude!
Thanks
...ANSWER
Answered 2020-Oct-14 at 13:34The problem seems to come from your wrapper functions rather than kableExtra
. If you inspect your df2
data.frame, you'll see that it includes a lot of \makecell
calls with weird alignment.
These makecells are inserted by the kableExtra::linebreak
function. To get the behavior you want, change your wrapper function with this:

Sorry about the long post. As I mentioned in the title I have a flask web app that takes in a url and sends it to the scrapy spider. The spider then goes through the response and scrapes the src of all found images.

Install crochet
READ board/board-name/README The board-specific directories each have a README with various details about running FreeBSD on a particular system. (Some boards have several README files in subdirectories with additional technical information.)
CREATE a config file Start by copying config.sh.sample. The first line specifies the board configuration you want to use. The name here should exactly match a directory under "board/". The configuration file can specify a wide variety of customizations for the generated image. The config.sh.sample file includes extensive documentation in the form of comments.
RUN crochet.sh as root $ sudo /bin/sh crochet.sh -c <config file> The script will first check that you have any needed sources. If you don't, the script will tell you exactly how to obtain the missing pieces. Follow the instructions and re-run the script until you have everything. As soon as it finds all the required pieces, the script will then compile everything and build the disk image. This part of the process can take many hours. Crochet keeps the built system, kernel, and other files between runs. In many cases, you can adjust the configuration and re-run crochet to build a new image in just a few minutes. However, if you update the FreeBSD sources or make a significant configuration change, you should probably delete the contents of the work directory to force everything to be rebuilt from scratch. Shortcut: If you only want the most basic build for a board, you can use this command without creating a config file: $ sudo /bin/sh crochet.sh -b <boardname> However, if you want to tweak the build in any way, you will need to create a config file.
COPY the image to a suitable device (SD card, disk drive, etc) The script will suggest a 'dd' command to do this.
BOOT the image on your board. Again, read board/board-name/README for details.
