check::assert_parameters for dynamic parameter input - c++11

I have a simple assert_parameters check for argument count. It goes something like this:
check::assert_parameters(argc, {"arg1", "arg2"});
Now, I want to add some optional parameters. How do I go about doing this?

Cypress: Can I use a value in the log as a string?

Currently I have my Cypress code writing out an email verification code to the log.
I need to take the six numbers from this value, to be inserted into a text field as a string.
The code I have in Cypress looks like this.
And the line of code related in the feature file looks like this.
I cannot pass the object into 'type' because it can only be a string or number.
Is there a way to take out the number element from the log to be used in the placeholderText part of the code I currently have?
It looks like email.text.codes[0] yields an object with one key (of value). So I think we'll just need to access that value field.
cy.get('foo')
.type(email.text.codes[0].value);

Is it possible to use findByRole for input of type search?

I am trying to select a search input using react-testing-library in the more semantic way possible.
I tagged the input with type=search, and I was expecting to be able to do something like this:
cy.findByRole('search').click().clear().type(content);
However the type fails because there is no element with the role search. Is this a limitation? Or is it supposed to be put in a different place? For example in a wrapping form? Currently the search input is just that, an isolated input that triggers search queries.
If you don't have an explicit role attribute on the element,
<input type="search">
the role to use is searchbox
cy.findByRole('searchbox').click().clear().type(content); // passes
If you want to use the command findByRole, then you have to tag your input as role="search", then the below command should work-
cy.findByRole('search').click().clear().type(content);

Shell help text syntax for repeatable group of arguments

I'm writing a help output for a Bash script. Currently it looks like this:
dl [m|r]… (<file>|<URL> [m|r|<index>]…)…
The meaning that I'm trying to convey (and elsewhere describe with words) is that (after a potential "m" and/or "r") there can be an endless list of sets of arguments. The first argument in each set is always a file or URL and the further arguments can each be "m", "r" or a number. After that, it starts over with a file or URL and so on.
In my special case, I could just write this:
dl [m|r]… (<file>|<URL>) (<file>|<URL>|m|r|<index>)…
This works, because listing a URL and then another URL with nothing in between is allowed, as well as listing an arbitrarily long chain of "m"s (it's just useless to do so) and pretty much any other combination.
But what if that wasn't the case? What if I had for example a command like this:
change (<from> <to>)…
…which would be used e.g. like this:
change from1 to1 from2 to2 from3 to3
Would the bracket syntax be correct here? I just guessed it based on the grouping of (a|b), but I wasn't able to find any documentation that uses this for multiple, non-exclusive arguments that belong together. Is there even a standard for this?

How to use wildcard attribute name and contains()?

In my problem I search for elements that have an example structure like:
<ngc-product-card ng-reflect-signup-type="comprehensive">
Since the elements may have the comprehensive value stored in another attribute, say:
<new-ngc-product-card data-label="comprehensive signup">
hence I would like to use a wildcard-attribute-name search and also apply the contains() function like:
//*[contains(#*,"comprehensive")]
which doesn't work
What does work is
//*[#*="comprehensive"]
Is there any way to use both '#*' and 'contains()' ?
This should do.
//*[#*[contains(., "comprehensive")]]

drupal multiple view arguments with PHP code validation for empty arguments

I have a view set up to accept 2 arguments. The url is like this: playlists/video5/%/%/rss.xml
It works fine if I supply the url with 2 arguments like playlists/video5/front/coach/rss.xml.
I have 2 arguments of "Taxonomy: Term"
But I need it to run even if 1 or no arguments are supplied. It looks like you can do this with PHP Code under: Provide default argument options -> Default argument type: -> PHP Code.
I'm using this for the first one:
$arg[0] == 'all';
return 'all';
I'm using this for the second one:
$arg[1] == 'all';
return 'all';
It's working fine in the preview if I enter 1, 2 or no arguments, but in the browser it giving me a "Page not found" error if I use less than 2 arguments in the url.
It woks with these urls:
/playlists/video5/gridiron/all/rss.xml
/playlists/video5/gridiron/football/rss.xml
It does not work with this:
playlists/video5/gridiron/rss.xml
I want it to return all values when no arguments are given, or if only one arg is given, just use the one, etc...
thanks
I would rearrange your URL to look like this: playlists/video5/rss/%/% so that way your arguments always come last. Then in your argument settings set:
Action to take if argument is not present: Display all values
This way when you go to playlists/video5/rss you will get every value. When you go to /playlists/video5/rss/term1 you will get all values that have term1 in them. Then the trick for the second argument is to include the wildcard for first argument like this: /playlists/video5/rss/all/term2. I believe that will include just the values that have the second term.
Alternatively, if these are both taxonomy terms, you may want to consolidate these into a single argument and check the box that says: Allow multiple terms per argument. According to the documentation right below the checkbox, it looks like this should allow you something like playlists/video5/rss/term1+term2 and display all values that have the first or second term.
Views will only collapse the %, not the slashes surrounding it. So while you're trying to use playlists/video5/rss.xml, Views is expecting playlists/video5///rss.xml.
To get what you're looking for, you need to duplicate the View display you're using twice.
For the first duplicate, use playlists/video5/%/rss.xml as the path. In your arguments for this view display, make sure the first argument validates for either gridiron or football.
For the second duplicate, use playlists/video5/rss.xml. There will be no arguments for this view display. If you just want all of the records to show up, you shouldn't have to do anything more. But if you want to supply a default argument other than all the records, you'd override the view display and create a filter instead of an argument.
Another (less ideal) option is to treat gridiron/football as one argument and validate it that way.
