ranges | C ranges components

I have a pair of iterator, and I would like to use ranges::views::filter(some_predicate) on it (with the pipe operator). AFAIU I should first convert my pair of iterator into a view. I tried to use ranges::subrange(first, last) to do so, but I’m getting horrible error messages.

Note1: I’m using C++14 and range-v3 version 0.9.1 (the last version compatible with gcc-5.5). If the solution differs when using C++17/20 and/or when using C++20 std::ranges, I’m also interested to know what changed.

Note2: I find the documentation of range-v3 severely lacking, so I’m using cppreference.com. If you know a better documentation, I’m very interested.

EDIT:

In my real code, I’m wrapping a java-style legacy iterator (that has a next() method instead of operator++/operator*. I’m wrapping them in a C++-compatible wrapper. Then I tried to convert that wrapper into a view, and finally filter it. I reproduce a minimal example on godbolt. This use iterator_range as suggested, but it still doesn’t compile (see the second edit below).

When setRows() run on an existing GridItem, the generated Form GridItem elements are fine, but the columns in the linked Sheet are reproduced in the next columns. The new columns are duplicates, but with a hidden property that shows that they belong to the Form (so we cannot delete the new columns). What is this property? The old columns are no more belong to the Form. The old columns may have existing values or previous Form responses.

How to prevent this?

The FormApp should handles the sheet Ranges properly, by looking for the existing columns and just adds the real new columns with new array of strings.

How did the Google Forms UI handle this: When we use the Forms UI, we can easily add new rows in GridItem, and the link Sheet will be updated without duplicated columns.

Here is the Form to test, and please create a new linked response-Sheet before running the code:

I'm working on backup solutions for mongodb instances using percona backup manager.

When I do pbm list if the PITR option is enabled, I get the output for snapshot and oplog slice ranges.

Is there a way to determine which oplog slice range belongs to which backup from the output programmatically so that I can associate an oplog slice range to a snapshot.

What happens if our query contains several tokens that finally there on different nodes? Are possible that the client runs multiple queries Sync or Async on nodes?

sample:

I'm trying to figure out how to fix this problem. I tried to use 'for loop' to set multiple ranges with one function but got error message.

'Exception: The parameters (String) don't match the method signature for SpreadsheetApp.ConditionalFormatRuleBuilder.setRanges.'

Here's my code.

I hope you're all doing well.

So I've been working with Excel my whole life and I'm now switching to Python & Pandas. The Learning curve is proving to be quite steep for me, so please bare with me.

Day after day it's getting better. I've already managed to aggregate values, input/ouput from csv/excel, drop "na" values and much more. However, I've stumbeled upon a wall to high for me to climb right now...

I created an extract of the dataframe I'm working with. You can download it here, so you can understand what I'll be writing about: https://filetransfer.io/data-package/pWE9L29S#link

I'm running gitlab-ce on-prem with min.io as a local S3 service. CI/CD caching is working, and basic connectivity with the S3-compatible minio is good. (Versions: gitlab-ce:13.9.2-ce.0, gitlab-runner:v13.9.0, and minio/minio:latest currently c253244b6fb0.)

Is there additional configuration to differentiate between job-artifacts and pipeline-artifacts and storing them in on-prem S3-compatible object storage?

In my test repo, the "build" stage builds a sparse R package. When I was using local in-gitlab job artifacts, it succeeds and moves on to the "test" and "deploy" stages, no problems. (And that works with S3-stored cache, though that configuration is solely within gitlab-runner.) Now that I've configured minio as a local S3-compatible object storage for artifacts, though, it fails.

I get this most common error message in shiny app. I am well aware of this error and have resolved it dozens of time. But this time I am stumped.

I have been following the leaflets tutorial where it is guiding on how to build an Interactive Choropleth map. Not all things are entirely included and once in a while I have to go online in an attempt to tweak things to get the to work. I got this point where I was labeling the population density of the states and my legend does not show a range in the labels like in this map and instead looks like this (in photo below).

Below is my code that gives the legend above
