is it possible to display a certain string in Textmate in a custom color?
Lets say I want to display the string "myCoolFunction()" always in yellow so I can see better where I use the function in my documents.
Actually it was possible. I modified the language pack. I am working with JavaScript so I edited the JavaScript language pack in TextMate. You have to create a new scope selector with a simple regex. After that you can create a new color rule in the settings and there you have it.
No, there aren't any syntax selectors for specific functions.

Am a newbee to javascript but have plenty of experience in VB, C, and even 86 assembler. Maybe I am trying to do the impossible in porting a VB app to js here. Basically, I need to change the color for only part of the string in an input element. Here is the problem:
A function takes an entered input box text field, and processes it first to see if it is in conformity to a set of requirements. If part of that string is not in conformity, I would like to in some way highlight that part in the input field. For instance, maybe I can send back the string to the input element (eg using the value attribute) but with some highlighting for that part, such as changing its text color or background color. Is this possible in js?
I'm not sure whether you can change colors of partial text in a simple text box. But what you're trying to do is certainly possible with this: https://editorjs.io/
The example on the homepage shows you how.
I hope this is a possibility for you and not too heavy for your purpose.
I was writing my own text editor in Electron using React and I tried to do some basic syntax highlighting. The user writes their code inside a textarea, but there is no way to insert markup inside a textarea so I can't color text that way.
I found this jquery plugin which adds a backdrop behind the textarea so we can put a background color in certain places however I wanted the text themselves to be colored (which can't be done as the textarea is in front of the backdrop).
Any ideas about how other IDEs like Visual Studio Code (also written in electron) pulled this off?
There are multiple approaches that can work here.
One way could be using a div with a contenteditable="true" attribute instead of a textarea. This way you can both write text inside the element and style its contents. Of course this creates its own issues that would have to be dealt with - when to parse the code, how to reposition the caret and more. Depending on the approach, MutationObserver could come in handy.
Another way would be to not use any built-in writing functionalities at all and implement your own. Listen to keyboard events and programatically insert characters. In that case you would also need to implement your own caret, selection etc., which is not easy.
VS Code is open source, so you can actually take a look under the hood and see how the editor is made. They use a completely bespoke editor called Monaco but its source code is in the VS Code repo. This file is a good start.
Is there a method to extract the code's color scheme from paypal code expamples and place it in sublime text?
Here is a link: Paypal link
That page is made using Groc, that put comments next to code in a beautiful way. Groc seems to use two projects that I have used before: highlight.js and maybe pygments, to highlight the code, but they don't use any of the default stylesheets, I think they use their own stylesheet.
Inside the Groc project you can see this sass file which contains almost all the info you need (color for variables, strings, keywords, etc.) to manually add the values to a custom color scheme. In addition Groc style documentation shows other useful values of the Color Scheme such as the background. You can get other values inspecting DOM.
I think you would have to manually do it. You can use this Sublime Text Color Scheme Generator. In the Paypal window, you can use developer tools (Ctrl + Shift + C if you're using Chrome) and click on the words to see the exact color value, and then just use those in the color scheme generator.
EDIT: Please take a look at #sergioFC's answer, he gave an easier way of finding all the color values.
What are the rules I need to follow, when creating a custom keyboard for a UITextView?
Is it OK to use a subclass of UIView?
Do I need to implement a specific protocol?
Should it contain a variable with a specific type and name?
Anything else?
At this point I have already made my own keyboard with the buttons; and it shows up when the UITextView object becomes the FirstResponder as expected. But I cannot use it and I would like to know if there is a "proper way" or if I just have to find my own way to make things work.
Thanks in advance.
Set inputView property of UITextView with your custom keyboard & refer to this link:
UITextView inputView
I have a requirement to use multiple font style in UITextView. Like Bold, Italic and Underline text in single Textview. Like:
One word is Bold second may be italic third Underline as per user selection.
I don't think this is allowed to do but still if any one have achieved and want to share. I need this all while enter text and same while displaying.
Thanks
You're right that the standard UITextView does not support rich editing. At the moment there are a few solutions to the problem.
The Omni Group has released their iOS and Mac frameworks under an open source license. These include a very powerful rich text editor (see: OUIEditorFrame.m). These are very powerful but also extremely complex. Their sample iPad app includes the rich text editor example. Further discussion can be found here
Secondly, this guy has been working on a custom rich text editing control and is offering it under a negotiable licensing agreement.
Finally, you can do it all yourself and create an editor control that implements the UITextInput protocol. Aside from the Apple documentation, there are some tips on doing this here.
Why don't you use attributed string and use its property to set the string as you like.
