Hi Christian, considder the snapshot down below and as bijlage. This genereate different results with the latest snapshot. No problem with 943 and the previous snapshot( BaseX944-20200911.135109) ============================================ declare %private function local:value1 ( $atomicItem as element( ) ) as item()* { $atomicItem/data() } ; declare %private function local:value2 ( $atomicItem as element( ) ) as item()* { trace( $atomicItem/data(), "test: ") } ; let $e := <E>test</E> return ( $e/data() , $e => local:value1() , $e => local:value2() ) ===========================================

issue: Add custom lib folder #1456
by Nicholas Saunders 25 Sep '20

25 Sep '20

For the Ubuntu install of BaseX, where's the "lib" directory for BaseX? Or, does the Ubuntu build just operate differently? see also: https://askubuntu.com/q/1276967/847449 thanks, Nick

Accessing Flexmark (Java) from Query
by Andreas Mixich 21 Sep '20

21 Sep '20

Hi, how can I translate this Java[1] to XQuery according to [2]? package com.vladsch.flexmark.samples; import com.vladsch.flexmark.util.ast.Node; import com.vladsch.flexmark.html.HtmlRenderer; import com.vladsch.flexmark.parser.Parser; import com.vladsch.flexmark.util.data.MutableDataSet; public class BasicSample { public static void main(String[] args) { MutableDataSet options = new MutableDataSet(); // uncomment to set optional extensions //options.set(Parser.EXTENSIONS, Arrays.asList(TablesExtension.create(), StrikethroughExtension.create())); // uncomment to convert soft-breaks to hard breaks //options.set(HtmlRenderer.SOFT_BREAK, " \n"); Parser parser = Parser.builder(options).build(); HtmlRenderer renderer = HtmlRenderer.builder(options).build(); // You can re-use parser and renderer instances Node document = parser.parse("This is *Sparta*"); String html = renderer.render(document); // "This is Sparta\n" System.out.println(html); } } I only get so far as to: declare namespace Node = "com.vladsch.flexmark.util.ast.Node"; declare namespace HtmlRenderer =" com.vladsch.flexmark.html.HtmlRenderer"; declare namespace Parser = "com.vladsch.flexmark.parser.Parser"; declare namespace MutableDataSet = "com.vladsch.flexmark.util.data.MutableDataSet"; declare option db:checkstrings 'false'; let $mds := MutableDataSet:new() let $builder := Parser:builder($mds) return $builder which results in DataSet{dataSet={}} I found no documentation, on how to translate something as Parser.builder(options).build() to XQuery. How do I express the method build() of the instance Parser.builder(options) I just created? Also, when I try the other way, by importing, for the following code import module namespace Node = "java:com.vladsch.flexmark.util.ast.Node"; import module namespace HtmlRenderer = "java:com.vladsch.flexmark.html.HtmlRenderer"; import module namespace Parser = "java:com.vladsch.flexmark.parser.Parser"; import module namespace MutableDataSet = "java:com.vladsch.flexmark.util.data.MutableDataSet"; let $mds := MutableDataSet:new() I get: [XQST0059] Could not instantiate com.vladsch.flexmark.util.ast.Node: java.lang.InstantiationException. Could it be, that it is only possible to call static properties via [1]? Am I right, that I need to write wrapper code in Java and then prepare results in a way, that I can retreive them from my own Java class? Thank you.

Full-Text-Search Options
by Günter Dunz-Wolff 19 Sep '20

19 Sep '20

Dear all, I’m using ft:mark with Options. In older versions of basex it worked fine, but with 9.3 I don’t get any results with the „distance" option and the „not in“ option. Maybe my syntax is deprecated? Example distance: ft:mark($ele[.//text() contains text {$query_string} all using wildcards using diacritics sensitive distance at most $distance words]) Example "not in": ft:mark($ele[.//text() contains text {$query_tokens} using wildcards using diacritics sensitive not in {$dont_find} using wildcards using diacritics sensitive]) Any help is appreciated. Thanks Guenter

Fulltext Distancing
by Adam Law 16 Sep '20

16 Sep '20

(: Hello - I saw some discussions about full text indexing. Dumbo here cannot work out how distance matching works. Also is it somehow possible to traverse up and down a full-index word list from a hit position rather than having to spend time say reversing strings. Is this is not possible due to how the word indexing works? If so can I preprocess https://github.com/pierrec/lz4/blob/master/fuzz/corpus/Mark.Twain-Tom.Sawye… to break it into words. I was considering making something like DTSearch (but more flexible) before I realised how difficult this is. Many thanks Dumbo :) import module namespace functx = 'http://www.functx.com'; (:fulltext <x><content><![CDATA[ https://github.com/pierrec/lz4/blob/master/fuzz/corpus/Mark.Twain-Tom.Sawye… ]]></content></x>:) (:$f - return all nodes containing queer and enterprises:) let $f := <x>{ft:search('xvue_textIndex',("enterprises", "queer"), map { 'mode': 'all' })/parent::* }</x> let $options1 := map { 'mode': 'all'} let $options2 := map { 'mode': 'all', "distance": map { "max": "5","unit": "words" }} let $options3 := map { 'mode': 'all words', "distance": map { "max": "5","unit": "words" }} let $options4 := map { 'mode': 'all words', "distance": map { "max": 5, "unit": "words" }} let $options := $options1 (:Why wont others work:) (:$g - mark words queers and enterprises.

Hi, when doing: html:parse(fetch:binary("https://ant.apache.org/manual/Tasks/chmod.html"), map{"method":"xml"}) and also html:parse(fetch:binary("https://ant.apache.org/manual/Tasks/chmod.html"), map{"method":"html"}) or html:doc("https://ant.apache.org/manual/Tasks/chmod.html") I get [html:parse] Line 23: </head> found, </link> expected. I use the BaseX version from 14 minutes ago ;-) (BaseX944-20200914.223814). -- Goody Bye, Minden jót, Mit freundlichen Grüßen, Andreas Mixich

missing web.xml from docker image
by Nicholas Saunders 15 Sep '20

15 Sep '20

I've just opened an issue: https://github.com/BaseXdb/basex/issues/1936 based on an inability to run the docker image: https://devops.stackexchange.com/q/12338/23443 but thought I'd ask here if there might be something obvious. I'm creating the container from the hub image with: docker run -d \ --name basexhttp \ --publish 1984:1984 \ --publish 8984:8984 \ --volume "$HOME/basex/data":/srv/basex/data \ --volume "$HOME/basex/repo":/srv/basex/repo \ --volume "$HOME/basex/webapp":/srv/basex/webapp \ basex/basexhttp:latest and another person reported the missing file. Is the file missing? I'm not sure.
