kandi X-RAY | crochet Summary

crochet is a Java library typically used in Plugin, IDE Plugin, Unity, Gradle applications. crochet has no bugs, it has no vulnerabilities, it has build file available and it has low support. You can download it from GitHub.

Checkpoint/rollback mechanisms create snapshots of the state of a running application, allowing it to later be restored to that checkpointed snapshot. CROCHET is a system for performing lightweight checkpoint and rollback inside of the JVM. CROCHET works entirely through bytecode rewriting and standard debug APIs, utilizing special proxy objects to perform a lazy heap traversal that starts at the root references and traverses the heap as objects are accessed, copying or restoring state as needed and removing each proxy immediately after it is used. The beauty of CROCHET is that you do not need to determine apriori what data should be included in a checkpoint. All that you need to do is ask CROCHET to perform a checkpoint (either starting with all root references or starting with a limited set of references), and then as your application traverses those objects, CROCHET will lazily make copies (on checkpoint, or restore on rollback) each object and its fields. This repository contains the source for CROCHET. For more information about how CROCHET works and what it could be useful for, please refer to our ECOOP 2018 paper, or email Jonathan Bell. The authors of this software are Jonathan Bell and Luís Pina.

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:

The 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.

Once you have populated your Leaflet GeoJSON Layer Group (typically with geojsonLayer.addData(geoJsonObject), then instead of adding that group to your map, simply add it into your MarkerClusterGroup:

QUESTION

Kableextra: after updating to R 4.0.3 and reinstalling, I cannot run correctly old script with multiline wrapped text in each cell

Asked 2020-Oct-14 at 13:34

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

The 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:
