I am trying to get text value in TMPro Text component without markup tags but haven't found any solutions.
Say, <b><color=red>Hello </color><b> world is the value in TMPro Text, and I just want Hello world in c# script.
Bear in mind that tag <b> and color will change, so I would love to remove tags dynamically, meaning I would like not to replacing each tag by text.replace("<b>", "") kind of things.
Does anyone know how to do it?
I dont know about the option of using HTML on tmp but you can attach the text to your script by create a new variable like that:
[SerializeField] TMP_Text textVar;
then you can drag you tmp game object to the component that include this script
and the you can change the text like that:
textVar.text = "what ever";
or get text like that:
string textString = textVar.text;
for the color you can use
Color color = textVar.color;
You can use TMP_Text.GetParsedText () to get the text after it has been parsed and rich text tags removed.
Alternatively you can also use regular expressions to search a string for rich text tags, and remove them while preserving the rest of the string.
using System.Text.RegularExpressions;
public static string GetString (string str)
{
Regex rich = new Regex (#"<[^>]*>");
if (rich.IsMatch (str))
{
str = rich.Replace (str, string.Empty);
}
return str;
}
I'm building a simple code editor to help children learn HTML. One feature I'm trying to add is that when users mouseover their rendered code (in an iframe), the corresponding HTML code in the editor is highlighted. So, for example, if a user mouses-over an image of kittens, the actual code, , would be highlighted in the editor.
Mousing-over the iframe to get the html source for that element is the easy part, which I've done (using document.elementFromPoint(e.clientX, e.clientY in the iframe itself, and posting that up to the parent) - so that's not the part I need help with. The part I can't figure out is how to search for and highlight that string of selected code in the code editor.
I'm using Codemirror 6 for this project, as it seems as it will give me the most flexibility to create such a feature. However, as a Codemirror 6 novice, I'm struggling with the documentation to find out where I should start. It seems like the steps I need to complete to accomplish this are:
Search for a range in the editor's text that matches a string (ie.'<img src="kittens.gif"').
Highlight that range in the editor.
Can anyone out there give me some advice as to where in the Codemirror 6 API I should look to start implementing this? It seems like it should be easy, but my unfamiliarity with the Codemirror API and the terse documentation is making this difficult.
1. Search for a range in the editor's text that matches a string (ie.'<img src="kittens.gif"').
You can use SearchCursor class (iterator) to get the character's range where is located the DOM element in your editor.
// the import for SearchCursor class
import {SearchCursor} from "#codemirror/search"
// your editor's view
let main_view = new EditorView({ /* your code */ });
// will create a cursor based on the doc content and the DOM element as a string (outerHTML)
let cursor = new SearchCursor(main_view.state.doc, element.outerHTML);
// will search the first match of the string element.outerHTML in the editor view main_view.state.doc
cursor.next()
// display the range where is located your DOM element in your editor
console.log(cursor.value);
2. Highlight that range in the editor.
As described in the migration documentation here, marked text is replace by decoration. To highlight a range in the editor with codemirror 6, you need to create one decoration and apply it in a dispatch on your view. This decoration need to be provide by an extension that you add in the extensions of your editor view.
// the import for the 3 new classes
import {StateEffect, StateField} from "#codemirror/state"
import {Decoration} from "#codemirror/view"
// code mirror effect that you will use to define the effect you want (the decoration)
const highlight_effect = StateEffect.define();
// define a new field that will be attached to your view state as an extension, update will be called at each editor's change
const highlight_extension = StateField.define({
create() { return Decoration.none },
update(value, transaction) {
value = value.map(transaction.changes)
for (let effect of transaction.effects) {
if (effect.is(highlight_effect)) value = value.update({add: effect.value, sort: true})
}
return value
},
provide: f => EditorView.decorations.from(f)
});
// this is your decoration where you can define the change you want : a css class or directly css attributes
const highlight_decoration = Decoration.mark({
// attributes: {style: "background-color: red"}
class: 'red_back'
});
// your editor's view
let main_view = new EditorView({
extensions: [highlight_extension]
});
// this is where the change takes effect by the dispatch. The of method instanciate the effect. You need to put this code where you want the change to take place
main_view.dispatch({
effects: highlight_effect.of([highlight_decoration.range(cursor.value.from, cursor.value.to)])
});
Hope it will help you to implement what you want ;)
Have a look at #codemirror/search.
Specifically, the source code implementation of Selection Matching may be of use for you to adapt.
It uses Decoration.mark over a range of text.
You can use SearchCursor to iterate over ranges that match your pattern (or RegExpCursor)
Use getSearchCursor, something like this:
var cursor = cmEditor.getSearchCursor(keyword , CodeMirror.Pos(cmEditor.firstLine(), 0), {caseFold: true, multiline: true});
if(cursor.find(false)){ //move to that position.
cmEditor.setSelection(cursor.from(), cursor.to());
cmEditor.scrollIntoView({from: cursor.from(), to: cursor.to()}, 20);
}
Programmatically search and select a keyword
Take a look at getSearchCursor source code it it give some glow about how it works and its usage.
So use getSearchCursor for finding text and optionally use markText for highlighting text because you can mark text with setSelection method of editor.
Selection Marking Demo
var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
lineNumbers: true,
styleSelectedText: true
});
editor.markText({line: 6, ch: 26}, {line: 6, ch: 42}, {className: "styled-background"});
And it seem this is what you are looking for:
codemirror: search and highlight multipule words without dialog
RegExpCursor is another option that you can use:
new RegExpCursor(
text: Text,
query: string,
options?: {ignoreCase?: boolean},
from?: number = 0,
to?: number = text.length
)
Sample usage at:
Replacing text between dollar signs for Mathml expression.
How to display form item label in Views exposed form instead of '- Any -'? To be more specific I use this code to replace select's default value text with custom text and want that custom text to be the label of that element:
function THEMENAME_form_views_exposed_form_alter(&$form, &$form_state) {
//dpm($form);
if ($form['#id'] == 'views-exposed-form-FORMID') {
$form['ITEMNAME']['#options']['All'] = t('My custom translatable text');
}
}
This works for custom text. What I want is to display its label instead of My custom translatable text with the simple code like:
$form['ITEMNAME']['#options']['All'] = $form['ITEMNAME']['#name'];
but have no luck on such and similar codes to work. According fo $dpm($form) output '#name', '#title' elements seem not to exist at all.
The goal is to have similar functionality of https://drupal.org/project/compact_forms or https://drupal.org/project/In-Field-Labels without another Javascript library (prefer to use couple PHP lines, please no JS solutions)
Your above code will work in case of select field but not for text field. If you need it to work for text fields you can try this
$form['ITEMNAME']['#attributes'] = array('placeholder' => array('My custom translatable text'));
or
$form['ITEMNAME']['#attributes'] = array('placeholder' =>$form['ITEMNAME']['#name']);
hope this helps you
Is there a easy way to just add a new form to a content element? Like I want an option selector where you can pick a color for the header.
Why not use the header_layout for that? You can customize it in the page-TSConfig
Like this:
# change labels of existing header_layouts
TCEFORM.tt_content {
header_layout.altLabels.0 = white
header_layout.altLabels.1 = red
header_layout.altLabels.2 = green
}
# add layouts
TCEFORM.tt_content{
header_layout.addItems.4 = blue
header_layout.addItems.5 = black
}
# remove layouts
TCEFORM.tt_content{
header_layout.removeItems = 3
}
That's will then set a class to the layout-number, and you can style it with css.
If you actually need a separate field, that's a bit more involved.
I am trying to insert id and name for image inside tinymce.
var content=tinyMCE.get('faq_answer').getContent()+"--img tag is given here--";
I can add image inside tinymce by giving alt, title but i cant add id and name.
If you want to add an element at the end of your editors content i would do something like this (this way you do not have to get all the editors content and set it again):
var doc = ed.getDoc();
// create a new img element
var img = doc.createElement('img');
img.title = 'title';
img.src = '/images/my_image.gif';
img.id = 'my_id';
img.name = 'imagename';
// add the new img element to the dom
ed.getBody().appendChild(img);
Some attributes may vanish (be cleaned up) depending on the configuration of valid elements. If this configuration is not set a standard rule set will apply. You may extend this rule set using the extended valid elements option. There is a nice example concerning img elements :)
