C-edit | A text editor in C with drop down menus from scratch No ncurses | Text Editor library

Edit: I didn't want to delete my post fully so edited it. I have found this code snippet:

I need to center a multiple line text in a div without using css, only with js. For example i have a div of 170px width, a SourceSansPro-Regular font and font size of 18px and this text for example :

I'm working on a commerce site using django. The logged in user has the ability to create a listing. I'm using django model to create a model and ModelForm for forms.

I'm attempting to add a new schema type to my Apostrophe-CMS project. I'm essentially trying to use Fabric.js to add an image designer as part of the pieces editor modal. I have a piece type that stores the JSON generated by Fabric.js as a field, and want the editor to show up in place of the field (or as the field) when editing the piece itself.

I have this partially working (following the guide at https://docs.apostrophecms.org/howtos/custom-schema-field-types.html). However, I'm running into an issue. The populate method of addFieldType seems to get called before the actual fieldset is rendered on the page. This would normally be fine since most fields have basic (if any) logic applied to them at render time, but in this case Fabric.js seems to require the canvas element to be present on the page, otherwise it can't connect to it correctly and fails to load.

I noticed in https://github.com/apostrophecms/apostrophe/blob/b22af9320169bf3af26cd17642373ae1e331a990/lib/modules/apostrophe-schemas/public/js/user.js on line 80 that it seems to imply that there's a way to override afterPopulate in custom field types. I can't seem to get this to work - I've tried adding it similarly to populate (seen below) but it doesn't ever get called (which makes sense looking at line 44 of the same file, since the only thing that gets called at that point on fieldType is populate).

Is there a way to override afterPopulate from a custom field type, or is there some other way I should be handling this? Right now I'm essentially adding a 500ms timeout in populate before initializing Fabric, which does work, but seems incredibly hacky. Here's the code that I've added so far:

According to the docs self.object exists for UpdateView

Template:

In Django 3.1, the typical DeleteView accepts GET and POST.

See https://docs.djangoproject.com/en/3.1/ref/class-based-views/generic-editing/#deleteview

and I reproduce below:

A view that displays a confirmation page and deletes an existing object. The given object will only be deleted if the request method is POST. If this view is fetched via GET, it will display a confirmation page that should contain a form that POSTs to the same URL.

How do I do a DELETEView that's class based view and also accepts DELETE method?

I'm trying to save the field values of a PHP form to a json file. I've tried a few solutions from this site which helped but I ran into an issue where it's not grabbing the field values and not returning any errors (I checked the logs). I am new to PHP so I'm probably making a noob mistake.

I am trying to use the solution posted here https://stackoverflow.com/a/17923066/1747477

Also, I need to replace the nested array with index "bundled_plugins" that is already present in the JSON file and not append it to the existing nested array. I'm using array_push but I know I need to use array_replace but I don't know how to target a specific index. If someone can point me in the right direction?

FORM

I'm trying to style the width/height (including min/max width and height) of my ckeditors. I've ran across this post (about styling .ck-editor__editable_inline), but the problem is that I have multiple instances of editors on a page, and want to have different heights/widths for different instances of editors.

I've tried manually hanging the minheight of the particular div with .ck-editor__editable_inline class through javascript (styling editor.ui.view.editable._editableElement), but upon focusing the editor, the styling disappears.

I am would like to edit my R chunks from RMarkdown files the way org-edit-special does. I found generic-edit-special from jonathan leech-pepin that does a similar thing for js, css and ruby in html files. I figured I could tweak it as suggested by the author to make it work for my case but I was not able to make it work even in its original form.

I was able to run the function ges/org-edit-special from a html file with a js script block but nothing happened (no error and no new buffer). I used the Internal Script example from here as html file for this test.

Here is the init.el I made for testing:
