Hey apparently people noticed that swap, unswap and groupcount are not on the "expression" page ... anyway could one of you guys put them in - I'd ask for permission, but what I write confuses people more than helps most of the time

thanks

Happy to. However, since you asked, can you PM me some good explanation overview links from the forum for each of those?

I know Swap() and Unswap() pretty well, but I'd like to refer to something from Matt explaining specifics when writing docs. And I don't know the deal with GroupCount() at all.

glynor · « **Reply #202 on:** January 20, 2016, 02:21:31 pm »

Swap() and Unswap() are done:
http://wiki.jriver.com/index.php/Expression_Language#Swap.28.E2.80.A6.29:_Takes_Firstname_Lastname_and_swaps_to_Lastname.2C_Firstname.

I haven't done GroupCount() yet.

blgentry · « **Reply #203 on:** January 20, 2016, 04:02:43 pm »

Each of your examples of swap() and unswap() seem backwards. Meaning you're using unswap() where you should be using swap(). Unless I don't understand it. I didn't think that this was correct:

unswap(Paul Simon)

Thank you for updating the docs.

I'm just trying to help improve the quality.

Brian.

dtc · « **Reply #204 on:** January 20, 2016, 04:31:54 pm »

Couple of problems, I think.

The swap() example uses an unswap example.

In the unswap description, it says swap() In the unswap example it has a swap example.

Should be swap(Paul Simon) and unswap (Simon, Paul)

The Sammy Davis example ignores the Jr. in the result. Is that correct?

glynor · « **Reply #205 on:** January 20, 2016, 05:07:07 pm »

I'll check. That page is a nightmare to edit because it was originally written to be machine generated by some script MrC cooked up, and is full of crazy tables with all kinds of HTML markup. I ~~might have~~ did mess something up.

The Jr. part surprised me, but that is right. I tested it. If you do:
Swap(Sammy Davis Jr.)

It removes the Jr suffix, and outputs: Davis, Sammy
MrC's original RegEx() did not. It would have outputted: Davis, Sammy Jr.

I don't really know which is "right".

glynor · « **Reply #206 on:** January 20, 2016, 05:11:01 pm »

Ok. I fixed it, and I added a note to the Sammy Davis Jr. example that makes it more clear what it does:

Quote

Handles most common name suffixes by removing them, and results in Davis, Sammy.

One thing I wasn't sure with this, because I don't use it heavily, is do these now work for semicolon delimited lists? They didn't originally, but I think perhaps that was added...

That page is a nightmare to edit because it was originally written to be machine generated by some script MrC cooked up, and is full of crazy tables with all kinds of HTML markup.

One of these days I want to break that monolithic page up into sub-pages for each of the major functional groupings, more like the COM Automation pages:
http://wiki.jriver.com/index.php/Media_Center_Automation

MrC liked his monolithic pages. I think because he didn't edit the wiki directly often, and used some crazy Perl scripts to allow him to edit them in a desktop application (probably BBEdit, knowing him). He also loved tables, which I hate dealing with in wiki markup. In any case, with some of "his" old pages, it has made editing them (post his departure)... Difficult.

But that's a major, and obnoxious, project. And, frankly, there is much more important stuff to be done (and, you know, I have much more fun things to do with my life). The Expression Language itself doesn't change that much (they don't give us new toys too often), so it isn't high on the priority list.

If anyone is a wiki editing wizard, though, and wants to take a crack at it...

That's incorrect. Your example in the docs has: swap(Sammy Davis, Jr.)

That comma is being interpreted as an argument I believe and it's being dropped entirely. You can put anything after the comma (foobar, baz) and it drops it. If you write it without the comma: Swap(Sammy Davis Jr.)

Then it works correctly and outputs: Davis, Sammy Jr.

Brian.

glynor · « **Reply #209 on:** January 20, 2016, 06:03:56 pm »

Oops. That explains it. I'll fix it.

Of course, about 1/2 of mine like that do have a comma. That's why I tested with that. I copypasted from MC. So, to use swap() right with those, you need to clean them of commas first.

glynor · « **Reply #210 on:** January 20, 2016, 06:26:09 pm »

Okay. I fixed it, but I found a bug.

The Unswap() command is useless as it is, for the same reason. You can't actually even do the simple example I provided in the documentation:
Unswap(Simon, Paul) results in Simon

To make it work, you have to escape the comma with a / and do Unswap(Simon/, Paul). But that's ridiculous because the command has no additional parameters, and it is designed to work with commas.

They should fix both of them. I'll mention it to Matt in a different thread.

blgentry · « **Reply #211 on:** January 20, 2016, 07:16:40 pm »

What you've reported is true. But I think it's a consequence of how MC interprets typed characters versus the values stored in fields. To whit:

unswap(swap(Paul Simon))

Produces: Paul Simon

Further, I just tested storing a swapped value in the Comments field. Then I made an expression column with unswap([comment]) . The expression column correctly unswapped the swapped value. So I think it's working as intended.

Finally, you asked about semi-colon separated values: Yes, it swaps each member individually. I tried it on [Director] for my movie collection and it swapped them all, including ones that had more than one director in the field.

Thanks again for your work on the docs.

Brian.

Ok, I wondered about that, but hadn't had a chance to test it yet (I was going to before I whined to Matt).

It treats input from a field value as a single argument (as though it is quoted on the command line), but there's no way to type that in manually (that I know of). It only works when you feed it with a field value (or, probably, the output of another expression).

That's fine, really. I can't imagine anyone in their right mind would use it with manually entered text. I just didn't know the expression engine did that. It isn't like I hardcode strings often, obviously!

I thought he'd fixed it, but it was in a different thread than the original Swap() and Unswap() one, and I didn't find it in a quick search. I was lazy and figured someone would answer.

Yes. Laziness pays off again!

I'll update the examples, and add in the stuff about lists. I might even add something further up in the page about arguments and commas.

It doesn't seem that crazy that commas need to be escaped.

I suppose we could make a special parsing mode that doesn't escape commas that are used just inside a few functions, but it sounds complicated and kind of gross!

According to Brian's test (I haven't tested yet myself), it's unnecessary. If you feed it with the output of a field (or, I assume, the output of another expression) then it works.

That's how people will use it in the real world. It just messed up my samples because I was typing them in manually. I'll test and confirm, but I think it is fine. I'll put something in the documentation to explain the samples.

Another test reveals that unswap() doesn't seem to like the swapped version of Jr. suffixes. For example:

unswap(swap(Sammy Davis Jr.))

That produces: Sammy Jr. Davis

I don't think that's the intended behavior.

glynor · « **Reply #220 on:** January 21, 2016, 09:13:13 am »

Matt, if you see this, can you comment about the "rules" for how expressions feed into other expressions?

Can I write something to this effect (worded better) in on the wiki page about expression arguments:

The output of an expression function (which includes field values) is always treated as a single input parameter when nested in another expression function. So that commas don't need to be escaped when they are contained in the output of an expression to be used as input on another expression function.

Such that:
if [Artist] = Simon, Paul
Unswap([Artist]) results in "Paul Simon"
and Unswap(Field(Artist)) also results in "Paul Simon"

Where using a string literal functions differently:
Unswap(Simon, Paul) results in "Simon" unless you escape the comma.

Is this right? Are there any cases where the expansion does not work that way?

That's exactly right. It's treated as "one unit" when it comes out of another function or argument, so escapement isn't necessary.

glynor · « **Reply #222 on:** January 21, 2016, 09:18:19 am »

Great. With that in mind, if you really love us, it would be pretty cool to have an expression function like this:
literal() which just does "this" (effectively the same as commenting the whole block).

Not really necessary since you can block escape text, but it would look less ugly in expressions and be a bit more readable.

I issued a major smackdown on the entire Expression Language page today:
http://wiki.jriver.com/index.php/Expression_Language

I broke out each of the Function "Types" (the groupings MrC made way back in the day) into their own pages, and those contain the actual documentation blocks for the different functions. But to ensure you can still Command/Control-F search the main page directly for functions by name, I included a nice index section that links directly to each function's documentation.

You can jump directly to the Functions section with this link:
http://wiki.jriver.com/index.php/Expression_Functions

And to the index:
http://wiki.jriver.com/index.php/Expression_Language#Function_Index

This keeps the Expression Language page itself much more manageable. Breaking up pages is always a balancing act between making the user click once more to access the information, and keeping the page readable and navigable. For this page, I think it was long-since past time.

More, I created a system of templates for creating each function-specific documentation block. This morphs the nearly-impenetrable blocks of HTML and wikitext tables into something much simpler to manage and modify, if needed. The set of templates includes:
* {{function description box}}
* {{argument table}}
* {{argument table row}}
* {{argument optional}}

When used, it turns the source of, for example, SaveAdd(), from MrC's version:

Code: [Select]

Not all of the new subpages are converted from MrC's old style to the new system, however. I only got through Conditional Functions as far as fully converting them. But the copied-and-tweaked versions that are there now are basically just as functional as they were.

For any new content, or tweaking existing content, of course, I'll convert them over. Perhaps I'll continue going through them by hand as well (which was actually good on the two sections I did, because I found some typos and other glitches), but we'll see.

Still didn't actually add GroupCount() which was what started all of this. But I'll get there.

Did a little more today. Got the function documentations "fixed" through Test and Comparison Functions now.

I also made redirects for all of the functions so that you can access them directly using URLs in this form:
http://wiki.jriver.com/index.php/Compare()
http://wiki.jriver.com/index.php/ConvertDate()

And so on and so forth. They all work, if they're in there now.

This lets me put them all in a category, which generates a by-name index of them:
http://wiki.jriver.com/index.php/Category:Expression_Functions

That's pretty cool.

But, I discovered something while doing it. Redirects to page sections don't work right on some browsers on the version of mediawiki that we're using. Specifically, on Mobile Safari on iOS (though possibly others, I saw some reference to the same issue on Opera and desktop Safari), it redirects to the top of the proper page, but not to the section.

I think this is something that has been fixed in more recent versions of mediawiki. I found a few threads about Wikipedia from back in 2007-2009 referencing this issue, but nothing since then. And, they do now work on Wikipedia, even if you turn off the mobile "theme", but they're on a much more modern version than us, and have all sorts of extensions installed.

I know redirecting to sections like that is done by Javascript after the page-redirection loads. So, it could be our common.js. I don't know though, as I couldn't find a bunch of instructions on how to fix it, just "it works now", which makes me think it was a mediawiki bug (or something they worked around). Not sure, but that seems dangerous to go spelunking after.

Still, though, they're useful (and on mobile safari it still gets you "close"), and you can use them in posts and whatnot and other places on the Wiki. Handy side-effect of re-working them.

http://wiki.jriver.com/index.php/Grouping_Functions

But... Phew! There is a paucity of information on these functions, and I haven't used them myself at all to build anything, so I don't have any experience. Back in the beginning (when it actually got added to the builds) Matt said:

I'll start a thread sometime in the next few days to explain this better and give some examples. I think it opens up a lot of neat possibilities.

I don't believe that ever happened, kind sir. Or if it did, I couldn't find it anywhere. Right now, my documentation is pretty terrible (effectively just links to two threads, and old ones). I kinda fudged the rest based on some of your background information, but it isn't stupendous. I'm not even positive that those two are all there are of the grouping functions. You'd mentioned them as part of a "class" and I saw a few oblique suggestions that there might be others, though they seemed inexact and "futurey"...

Also, you'd mentioned this:

Quote from: Matt on December 09, 2013, 03:37:51 pm

This might be a nice extension of the new class of Group...(...) functions.

What's better:

GroupSummary(Disc #, max)
or
GroupMax(Disc #)

I don't know, but I don't think anything was ever done here. For the record, I think GroupSummary(field, mode) is definitely the way to go. Mode 0 can be Automatic, just like the current function, and then 1 through whatever would be...

Functions to ask explicitly for mode, mean, min, max, etc. would be a nice addition.

So... I don't know what to do here. At least it is something for now, though!

if you guys want a working example to cut and paste for the Literal(...) function

this works nice (and it also removes the dreaded time stamp for my audio files which mucks things up for me

)

After reimporting the local media, the new field's data could be used for stats and views instead of the actual date imported field. Also, it's a way to save stats if you have to re import media files or write back file tags to the library.

Code: [Select]

=Literal([Date Imported])Now this works great. The result I get is something like this
19/08/2013 22:32

and when adding the expression to remove the time from the output using RemoveRight(...)

Code: [Select]

=removeright(literal([Date Imported]),6)
Removes the trailing old value [ 22:32] from the original string, resulting in 19/08/2013. Because no new string is specified, the default empty value is used as a replacement, effectively stripping the old value.

This thread is kind of long and scary.

But the function:
GroupSummary(...)

Was added. From the comment:
"Get a summary for the current group of files.

Field: the name of the field to summarize
Example: GroupSummary(Rating)"

And it does summarize groupings when used in a pane, etc.
