I tried to search how i can change the web editor for my Xtext project. But it seems there is missing some documentation.
My question is how can I change the default web editor ace to my prefered editor orion ?
you need to do two things
adapt the workflow to use orion webSupport = { framework = "Orion"} (best done before first generation since generate once files will not be overriden)
since there is no webjar for orion you need to download/unpack it manually and or separately depending on your build system.
you may have a look at the Yeoman generator-xtext (https://github.com/itemis/generator-xtext) which allows you to create a gradle + xtext + web + orion project.
Workflow {
component = XtextGenerator {
...
language = StandardLanguage {
name = "org.xtext.example.mydsl.MyDsl"
fileExtensions = "mydsl"
serializer = {
generateStub = false
}
validator = {
// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
}
webSupport = {
framework = "Orion"
}
}
}
}

Context - I am trying out Postgres' Geographic Information System extension PostGis that enables stories latitude and longitudes as Point and operations on it.
If I understand correctly then I need to add a custom converter that can convert the point between JOOQ and PostGis and add it to the gradle file.
Problem - When I generate the jooq-code, few files are generated incorrectly and have the fields defined twice which fail compilation. These are:
<configured-generation-dir>/tables/StValuecount.java
<configured-generation-dir>/tables/records/StValuecountRecord.java
<configured-generation-dir>/tables/records/StValuepercentRecord.java
<configured-generation-dir>/tables/_StValuecount.java
<configured-generation-dir>/tables/records/_StValuecountRecord.java
<configured-generation-dir>/tables/_StHistogram.java
<configured-generation-dir>/tables/records/_StHistogramRecord.java
<configured-generation-dir>/tables/_StQuantile.java
Gradle config =>
jooq{
myAwesomeApp(sourceSets.main){
logging = 'WARN'
jdbc {
driver = 'org.postgresql.Driver'
url = db_url
user = db_user
password = db_password
}
generator {
name = 'org.jooq.codegen.DefaultGenerator'
strategy {
name = 'org.jooq.codegen.DefaultGeneratorStrategy'
}
database {
name = 'org.jooq.meta.postgres.PostgresDatabase'
inputSchema = 'public'
forcedTypes {
forcedType {
userType = 'org.postgis.Point'
converter = 'com.example.JooqBreaksWithPostGis.jooq.converters.PostgresPointJooqConverter'
expression = '.*\\.point'
types = '.*'
}
}
}
generate {
routines = false
relations = true
deprecated = false
records = true
immutablePojos = false
fluentSetters = true
}
target {
packageName = 'jooq.fancy.app'
directory = 'src/main/java/generated'
}
}
}
}
What am I doing wrong?
I have also created a minimal project where I have reproduced the problem in case someone wants to quickly try it.
Steps to reproduce
Checkout project
git clone git#github.com:raj-saxena/JooqBreaksWithPostGis.git
Go to the project directory and start postgis docker container with
docker-compose up
Similarly, to remove postgis docker container run
docker-compose down
Run migrations that add a simple City table containing Point type with
./gradlew flywayMigrate
I have added few rows in a second migration to verify if the DB structure was working. Details to connect to Postgres instance in the build.gradle file.
Generate jooq files with
./gradlew generateMyAwesomeAppJooqSchemaSource
Verify that the files are generated in the configured src/main/java/generated directory.
Verify that the files mentioned above fail to compile.
Taking Lukas' advice, I added the exclude configuration to the jooq config as below:
database {
name = 'org.jooq.meta.postgres.PostgresDatabase'
...
excludes = '.*ST_ValueCount' +
'|.*St_Valuepercent' +
'|.*St_Histogram' +
'|.*St_Quantile' +
'|.*St_Approxhistogram' +
'|.*St_PixelOfValue' +
'|.*St_Approxquantile' +
'|.*ST_Tile'
}
This allowed the code to compile.
This sounds a lot like https://github.com/jOOQ/jOOQ/issues/4055. jOOQ 3.11 currently cannot handle overloaded table valued functions in any RDBMS that supports table valued functions. Your best option here is to exclude all the affected functions from the code generation, using <excludes>:
https://www.jooq.org/doc/latest/manual/code-generation/codegen-advanced/codegen-config-database/codegen-database-includes-excludes/
I'm kind of new to xtext and I'm working on an already given Language. I now want to use the StandaloneSetupGenerated class but the extension used for the registry is not the one used for the files. So the setup wont match. Where does the StandaloneSetupGenerated gets this extension from, so where do I need to change the param for the generated file to match my real file extension.
The part of the workflow looks like:
component = Generator {
pathRtProject = runtimeProject
pathUiProject = "${runtimeProject}.ui"
pathTestProject = "../../tests/${projectName}.tests"
projectNameRt = projectName
projectNameUi = "${projectName}.ui"
encoding = encoding
language = auto-inject {
fileExtensions = file.extensions
uri = grammarURI
the property file.extensions provides the right extension but is not the one used in the generated StandaloneSetup.
the file extensions are configured in the language workflow
language = StandardLanguage {
name = "org.xtext.example.mydsl.MyDsl"
fileExtensions = "mydsl"
in xtext <= 2.8.4 style workflows it is
var fileExtensions = "mydsl"
Even though I have already changed the API Compatibility Level from .NET 2.0 Subset to .NET 2.0 in Edit->Project Settings->Player under Optimizations, upon upgrading to Unity 5.3.0 I am still getting the following two error messages:
`System.IO.File' does not contain a definition for `AppendText'
`System.IO.File' does not contain a definition for `CreateText'
They refer to the following code snippets:
using(StreamWriter writer = File.CreateText(saveFilePath))
{
string sLine = "time;joint;pos_x;pos_y;poz_z";
writer.WriteLine(sLine);
}
using(StreamWriter writer = File.AppendText(saveFilePath))
{
string sLine = string.Format("{0:F3};{1};{2:F3};{3:F3};{4:F3}", Time.time, (int)joint, jointPos.x, jointPos.y, jointPos.z);
writer.WriteLine(sLine);
}
How do I resolve this?
Are you tried this case?
using (var f = new StreamWriter("file path", true))
{
f.WriteLine("appended text");
f.Flush();
}
I'm trying to create a plugin for JSDoc.
I'm following the documentation (which, ironically, is lacking) and I'm not sure how to do this.
My plugin is loaded properly, and I'm trying a simple example. Here's my plugin (which loads, because I can throw an error from there to stop jsdoc from running):
visitNode: function(node, e, parser, currentSourceName) {
if(node.type === 109){
if(!e.comment || e.comment ==="#undocumented"){
var startComment = '/**',
endComment = '\n*/';
var params = node.getParams(),
paramsComment = '';
for(var i=0; i<params.length; i++){
paramsComment += '\n* #param ' + params[i];
}
e.comment = startComment +
paramsComment +
endComment;
}
}
please note that node.type === 109 is equivalent to Token.FUNCTION, which should be available as per their example here, but Token is undefined in the plugin.
If you know of a better site which explains how to write a JSDoc plugin, then that would be very much appreciated too... thanks
I also had this problem and it seems strange that JSDoc does not have some kind of already made option for that or at least a plugin.
Anyway creating this plugin has solved my problem. I am using JSDoc version 3.4:
'use strict';
exports.handlers = {
symbolFound:function(e) {
if(e.astnode.type === "FunctionDeclaration" ) {
if( (e.comment==="#undocumented")){
e.comment = '/** undocumented */';
}
}
}
};
I had a look at the documentation on enrolments, but all the enrolment methods seem to involve some interaction with the GUI.
Is there a way to script enrolments? Something like:
./moodle_do_enrolments imsdata.xml
Or even some web services calls that I can call from an external program?
I'd like to be able to do the following in an automated fashion:
1) Add a user.
2) Create a course with specified title etc.
3) Enrol that user in that course.
Of course at some point I'd hook this up with our user systems and other management systems, but for the moment, I'm just trying to do a proof of concept.
Where is some documentation that explains the process of automated enrolments?
You could try to create your own PHP script: parse the XML file and use internal moodle functions to solve the problem.
Basic ideas to solve these problems
1) Add a user:
In user/lib.php is a method: user_create_user($user).
Just include that lib.php and find out which information is needed in the user object.
2) Create a course
In course/lib.php is a method: create_course($data, $editoroptions).
Just include that lib.php and find out which information is needed in data array.
3) Enrol a user
I created the following method to do the job for me.
// enroll student to course (roleid = 5 is student role)
function enroll_to_course($courseid, $userid, $roleid=5, $extendbase=3, $extendperiod=0) {
global $DB;
$instance = $DB->get_record('enrol', array('courseid'=>$courseid, 'enrol'=>'manual'), '*', MUST_EXIST);
$course = $DB->get_record('course', array('id'=>$instance->courseid), '*', MUST_EXIST);
$today = time();
$today = make_timestamp(date('Y', $today), date('m', $today), date('d', $today), 0, 0, 0);
if(!$enrol_manual = enrol_get_plugin('manual')) { throw new coding_exception('Can not instantiate enrol_manual'); }
switch($extendbase) {
case 2:
$timestart = $course->startdate;
break;
case 3:
default:
$timestart = $today;
break;
}
if ($extendperiod <= 0) { $timeend = 0; } // extendperiod are seconds
else { $timeend = $timestart + $extendperiod; }
$enrolled = $enrol_manual->enrol_user($instance, $userid, $roleid, $timestart, $timeend);
add_to_log($course->id, 'course', 'enrol', '../enrol/users.php?id='.$course->id, $course->id);
return $enrolled;
}
Using a GUI is not necessary, you can create an enrolment/authentication plugin to achieve this or use one of the built in ones. I'm not too familiar with the ims enrollment plugin, but the standard ldap/database plugins have scripts which can be used to automate this sync process.
See for example:
enrol/database/cli/sync.php
