Hi Christian,

I think there is a bug for Mac (10.x). Those options do no work and typing quotes is really difficult. First I need to press the button twice in order for one quote to appear. Then whatever button I use the other quote appears. And there are other strange behaviors which are difficult to detail (eg the cursor is moved outside adjacent quotes if the option "automatically add characters" is on).

Whitespaces cannot be shown, only new line character (this happens also on a windows machine).

Joseph

ps I also notice that running basexgui and basex.jar are different. I added saxon9he.jar in the lib folder and it is read by basexgui but not by basex.jar. Moreover basexgui sometimes runs out of memory when basex.jar does not. Does this make sense?

Hi Joseph,

I love using the gui but I have a hard time dealing with autocomplete: is there a way to disable it in the txt editor?

You can disable "Automatically add characters" in the Preferences dialog. Could you please detail which autocompletions are particularly confusing for you?

I think that it would also be very useful to allow view of whitespaces and tabs and have a function to prettify the code itself (do you know any for xquery?)

Tabs and non-breaking spaces are visualized when activating "Show invisible characters" in that same dialog.

I mean the double or single quotes button. I need to press it twice to see the first quotes appear. Then I can press a character button and the other quotes will show up. Thanks!

Hi Jopseph,

Thanks for the details.

One more question: What 'button' do you mean here?

Whitespaces cannot be shown, only new line character (this happens also on a windows machine).

Exactly, we are only visualizing "non-breaking whitespaces" at the moment (\u00A0). This may be changed in future.

ps I also notice that running basexgui and basex.jar are different. I added saxon9he.jar in the lib folder and it is read by basexgui but not by basex.jar. Moreover basexgui sometimes runs out of memory when basex.jar does not. Does this make sense?

If you directly run the JAR file, no other libraries will be embedded in the classpath. This is why we also provide the start scripts. You can adjust the maximum amount of assigned memory in the scripts files; look for the -Xmx flag.

Hope this helps, Christian

Hello Ron,

not Christian, but I try anyway to help you :)

If you say yout want a "generate consecutive numbers in a for loop" are you aware of the "at" construct for flwor expression, e.g.

for $x at $pos in 10 to 19 return $pos

will return the numbers 1 to 10, i.e. is a consecutive counter.

Cheers Dirk

Hi Christian,

Is there a way to generate consecutive numbers in a for loop in BaseX? I am iterating over a collection of XML files from clinicaltrials.gov and need to tag each output record with a unique ID starting at 1. I have seen many discussions of this (some involving incrementing a counter in a dummy node) but have not found a clean solution that actually works. For example, I tried to adapt the code snippet you provided in https://mailman.uni-konstanz.de/pipermail/basex-talk/2010-May/000259.html to create a function that accomplishes this without referencing an auxiliary file (see below) but cannot get past the perplexing syntax error ([XQST0049] Duplicate declaration of static variable $root.).

Thanks, Ron

declare variable $root := <root count="0"/>;

declare function local:getuid () as xs:integer { let $count := $root/@count return ( insert node <node id='{ $count }'/> into $root, replace value of node $count with $count + 1 ) };

Some time ago, we provided .dmg/.app distributions. As Apple expects those files to be decorated with a signature, and as we have to pay for those signatures (whereas we don't charge for BaseX at all), we stopped providing those distributions. However, we may introduce them some time in future, let's see.

You can find .app.tar.bz2 bundles of the latest official and snapshot release in our BaseX here [1].

With regards to the GUI, is there a .dmg for the Mac? The BaseX website directs to brew but it appears this implies using the GUI that comes in the jar. I tried it recently but it did not work properly (was unable to type into it).

Hi Rob,

A short variant of your approach could look like this:

import module namespace counter = 'java.util.concurrent.atomic.AtomicInteger'; for $i in 1 to 10 return counter:incrementAndGet()

As you already indicated, it violates the functional programming design, so I would surely recommend everyone to use the GFLWOR "at" or "count" clause (or possibly fold-left, etc.)

And hi Ron,

Do you need to start with an existing counter when running your query, or is it sufficient to start with 1?

Christian

Thanks all!

I went with the solution suggested by Christian. It is simple, efficient, and solves my problem (starting at 1 is fine). The GFLWOR approach is nice, except that I have two nested for loops so it produces two counts instead of one (and there is no straightforward way to combine them into a single monotonically increasing number).

One last question. The serializer has trouble with tags that contain underscores. For example, I get the following error:

When I remove the underscore the error goes away (I inject these tags in the result clause).

Underscores should be fine in XML node names (e.g., clinicaltrials.gov uses them extensively).

Is this issue related to the XQuery specification or unique to BaseX?
