cyclic type declarations
by Rob Stapper 14 Apr '26

14 Apr '26

Hi Christian, Just made the next observation: In case of cyclic type declarations the editor throws a "unknown-type:"-error. Module:M0 is a agregate of modules: M1 and M2, and declares a agregated type using type declarations of both imported modules. Modules M1 and M2 declare ther own type but M2 also imports agregated module: M0. This import of MO in M2 causes in this usecase an "unknown type:-error. This is unwanted. Hope it is an easy fix. mvgr. Rob Stapper

Hi, I have these inline callback functions that sometimes take an extra parameter. I was wondering if it is possible and feasable that also inline functions support default values. Thnx in advance for your response. mvgr. Rob Stapper

Saxon functions in XQuery or alternatives
by France Baril 04 Apr '26

04 Apr '26

I am trying to to grab the line and colum number of an expression found with ft:search to better integrate results for dynamic interaction in an XML editor. I was hoping to use saxon:line-number, saxon:character-number, but they are unavailable in BaseX XQuery, only available in xslt:transform. Do you have suggestions on how to extract these details from what's available right now in XQuery?

Hello, I was testing the feature https://docs.basex.org/main/XQuery_4.0#methods, but the examples raise the error XQST0045 let $vector := { 'x': 5, 'y': 6, 'sum': %method fn() { ?x + ?y } } return $vector =?> sum() let $number := { 'value': 1, 'inc': %method fn() { map:put(., 'value', ?value + 1) } } return $number?inc() -- LSC Eliud Santiago Meza y Rivera

Re: Help adding "bulk" txt files

Hello, You can reduce: file:list($path, false(), '*.txt')[starts-with(., 'retrospect-')] to the following: file:list($path, false(), 'retrospect-*.txt') It is up to you to test and compare both approaches: #1 vs. #2. Regards, Yitzhak Khabinsky

Help adding "bulk" txt files
by Bridger Dyson-Smith 23 Mar '26

23 Mar '26

Hi all - I'm wondering if you all would share better ways to approach the following problem: I have a directory of files but I only want to put a subset of the files into a BaseX database. After some fumbling around, I have these two approaches, but... what are your thoughts? Can I simplify this somehow? I struggled initially with filtering the files down - while I know I could have thrown everything in the directory into a db, there are some fairly large binaries and disk space is precious :) - so I couldn't get a way forward through using commands, but maybe I overlooked something. Thanks for your time! Best, Bridger #1 (: relies on running 'CREATE DATABASE cco' as a first step :) declare variable $path := "/home/bridger/Downloads/cco/"; for $m in file:list($path, false(), '*.txt')[starts-with(., 'retrospect-')] let $n := substring-after(substring-before($m, '.txt'), 'cob-') let $t := element text { file:read-text($path || $m, 'UTF-8', true()) return updating db:add(?, ?, ?)('cco', $t, $n) #2 declare variable $path := "/home/bridger/Downloads/cco/"; declare variable $filepaths := file:list($path, false(), '*.txt')[starts-with(., 'retrospect-')]; declare variable $files := ( for $f in $filepaths let $t := element text { file:read-text($path || $f, 'UTF-8', true()) } return $t ); declare variable $names := ( for $f in $filepaths let $n := substring-after(substring-before($f, '.txt'), 'cob-') return $n ); db:create( 'nothertest', $files, $names, { 'ftindex': true(), 'textindex': true() } )

NullPointer when job is running
by Darryl Pretto 18 Mar '26

18 Mar '26

Hi, I am running the BaseX webapp deployed on a Jetty server. I’m trying to upgrade to BaseX 12.2, running with Jetty 12.1.7. When I run a job using job:eval I find that the Jobs tab in the web UI displays the below error/stack trace while the job is running. The job itself is running a proc:system command that runs a script that makes a REST call to a web service and then uploads the data into a BaseX db. It takes 2-3 minutes to complete. The error doesn’t occur every single time the job is run, but often. I have reproduced it both on my local Mac and on a server running Amazon Linux. It doesn’t seem to happen when I use BaseX 12.2 with Jetty 11.0.24. It may not be a significant problem. Despite the error the job still completes, so it doesn’t affect anything other than the jobs tab display in the Web UI. But it is odd and I wonder if anyone has any idea what the issue might be. Also, is there any drawback to using Jetty 11 (other than it being deprecated)? Thanks, Darryl Unexpected error: Improper use? Potential bug?

How do I determine which web protocol to use?
by Ben Engbers 18 Mar '26

18 Mar '26

Hi, I’ve been working on implementing the WebSocket protocol in my C++ client for just over a month now. I started with the assumption that the basexserver uses the WebSocket protocol by default. I can now finally send and receive WebSocket frames. But even when performing the opening handshake, I see that after sending a request, I don’t receive a WebSocket frame in return. Instead, I get the standard realm/nonce that I’m already using in my current client which is based on a raw web connection. The developers section of the Basex documentation discusses the WebSocket protocol. In web.xml, I see that the WebSocket service is enabled. Yet I’m not getting the expected response. My question is: where is my mistake? What do I need to do to use the WebSocket protocol as a client? While modifying the code, I did make a few improvements. I also updated the documentation. I’ll upload my code one of these days. Ben By the way, I’ve learned a lot about C++ programming ;-)
