contextual is a Scala library typically used in Template Engine applications. contextual has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

An interpolated string is any string literal prefixed with an alphanumeric string, such as s"Hello World" or date"15 April, 2016". Unlike ordinary string literals, interpolated strings may also include variable substitutions: expressions written inline, prefixed with a $ symbol, and—if the expression is anything more complicated than an alphanumeric identifier—requiring braces ({, }) around it. For example,. Anyone can write an interpolated string using an extension method on StringContext, and it will be called, like an ordinary method, at runtime. But it's also possible to write an interpolator which is called at compiletime, and which can identify coding errors before runtime. Contextual makes it easy to write such interpolators.

            Swing JMenuBar not rendering properly
            Asked 2021-Jun-15 at 18:31

            First time actually using anything to do with swing - sorry for the poor code and crude visuals!
            Using swing for a massively over-complicated password checker school project, and when I came to loading in a JMenuBar, it doesn't render properly the first time. Once I run through one of the options first, it reloads correctly, but the first time it comes out like this: First render attempt
            But after I run one of the methods, either by clicking one of the buttons that I added to check if it was just the JFrame that was broken or using one of the broken menu options, it reloads correctly, but has a little grey bar above where the JMenuBar actually renders: Post-method render

            The code for the visuals is as follows:

            My problem is that I have some HTTP POST requests that returns no data. Only a HTTP 200 on success. I can't figure out how to create a publisher that will handle a decoding that can fail since there could be not data in the body of the response. Here's what I tried:

            Why can't comments appear after a line continuation character?
            Asked 2021-Jun-09 at 23:06

            Why does Python not allow a comment after a line continuation "\" character, is it a technical or stylistic requirement?

            According to the docs (2.1.5):

            A line ending in a backslash cannot carry a comment.

            and (2.1.3):

            A comment signifies the end of the logical line unless the implicit line joining rules are invoked. Comments are ignored by the syntax.

            PEP 8 does discourage inline comments so I can see how this may stylistically be "unpythonic." I could also see how the "\" could be ambiguous if it allowed comments (should the interpreter ignore all subsequent tokens or just comments?) but I think a distinction could easily be made.

            Coming from Javascript and accustomed to the fluid interface style, I prefer writing chains like the following instead of reassignment:

            For the same reason you can't have whitespace after the backslash. It simplifies the parsing, as it can simply remove any backslash-newline pairs before doing any more parsing. If there were spaces or comments after the backslash, there's no backslash-newline sequence to remove.

            There is a way for Compose add-ins to run automatically based on certain events in requirement set 1.10, but there isn't a similar feature for Read add-ins.

            Contextual add-ins still require interaction from the user to launch the add-in.

            A user could pin a task pane add-in, and it would launch automatically, but this requires an action from the user, and the add-in would always be visible.

            For part of the scenario you described, you want to get the text of the email. This could be possible from a backend service using change notifications in Microsoft Graph, which could notify the service whenever a user receives an email. Though, this would trigger on every message, not just messages read by the user.

            How to add a small bit of context in a grammar?
            Asked 2021-May-29 at 00:22

            I am tasked to parse (and transform) a code of a computer language, that has a slight quirk in its rules, at least I see it this way. To be exact, the compiler treats new lines (as well as semicolons) as statement separators, but other than that (e.g. inside the statement) it treats them as spacers (whitespace).

            As an example, this code:

            ...

            ANSWER

            Answered 2021-May-29 at 00:22

            The relevant quote from the "specification" is this:

            A squirrel program is a simple sequence of statements.:

            stats := stat [';'|'\n'] stats

            [...] Statements can be separated with a new line or ‘;’ (or with the keywords case or default if inside a switch/case statement), both symbols are not required if the statement is followed by ‘}’.

            These are relatively complex rules and in their totality not context free if newlines can also be ignored everywhere else. Note however that in my understanding the text implies that ; or \n are required when no of the other cases apply. That would make your example illegal. That probably means that the BNF as written is correct, e.g. both ; and \n are optionally everywhere. In that case you can (for lark) just put an %ignore "\n" statement and it should work fine.

            Also, lark should not complain if you both ignore the \n and use it in a rule: Where useful it will match it in a rule, otherwise it will just ignore it. Note however that this breaks if you use a Terminal that includes the \n (e.g. WS or /\s/). Just have \n as an extra case.

            (For the future: You will probably get faster response for lark questions if you ask over on gitter or at least put a link to SO there.)
