Use Javascript library : please need help

Post by UltraVox »

Hello everyone,

I would like to use this javascript library (https://highlightjs.org) in my NB app., to easily edit LUA code. However, I have never done this before. I have trouble setting with the thing. Someone would be kind enough to help me ? I would just like to load an LUA code editor into a NeoBook WebBrowser object. So, I would need (I guess...) an HTML page, with a piece of code required to display the thing (?).

The site offers to download a small package, with the language of our choice.
So, for me, only the LUA language is required : https://highlightjs.org/download/

Your help would be welcome.

Of course, if you know another javascript library (or another method), easier and/or better for edit the LUA code, I am waiting for your feedback.

Thank you very much.

You need an editor with code highlight (Ace/Scintilla/EditArea etc...), not just regular static code highlighter.

1) I do not have experience with "highlighter", but it appears to be just a facility to "highlight" code (written in many different languages) ... I do not think it is a "text editor" i.e. I do not believe you can make/save changes to the highlighted code ... almost all things that run inside Browsers can NOT save to files on your local disk (for security reasons).

Even this YouTube Tutorial ... https://www.youtube.com/watch?v=y-0jqM9EeVM ... uses Notepad+ to setup the demo HTML file.

2) What is your purpose for running this "hilighter" inside a WebBrowser object ? ... as opposed to viewing it stand-alone (as an HTML file within your Browser) ?

Do you need to send Lua code to this "highlighter" from your NeoBook application ? ... according to this page ... https://highlightjs.org/usage/ ... you have to insert your code between <pre> and </pre> tags in your html file ... so, assuming that you ...

a) only need to highlight your code (not edit/save it)
b) have manged to make "highlighter" work as a standalone file

... you would just need to specify this html file (your code surrounded by html/javascript) in order to view it inside a WebBrowser object ... if you want to avoid this process of wrapping html/javascript manually, then you would have to setup a template file ... and then each time, use NeoBook commands to ...

a) do the insertion/replacement of your Lua code in the template
b) save the modified template to another temporary file
c) view the temporary file in your WebBrowser object

Hum, Thanks for your advices, Gaev and Tony.
Obviously, Highlight.js is not what I'm looking for !

I am looking for a free tool, redistributable (so, probably open-source and with an appropriate license) that can Open a .lua file, edit it, modify it and save it, if possible with a customizable appearance (Colors, Fonts ...), as in Pro code editors.

I do not care if it's done in a WebBrowser object, a Rectangle, or whatever you want. The important thing is that it works properly and that it is legal.

The easiest way would be download SciTE and run it in rectangle (and interact via SendKeys)

Thank you Tony and Gaev, it works well.

This SciTE version is different from that of Gaev, right ?
Can it change the default theme ? My application is dark.

If you know how to change the theme, to put something darker, I'm interested.

Thank you for your help.

SciTe is highly configurable ... the specific methods for doing so depend on the version that you downloaded (things change from version to version) ... don't know if the latest version has detailed help information about each of the properties/options.

If not, I advise that you ...

- examine the (text) files that were included in the downloaded package
- make a copy of the original file
- edit the approrpriate line to see what it does

I downloaded this version :https://www.scintilla.org/wscite405.zip
And there are 82 *.properties files in the root of SciTE.exe ^^

So, I looked for themes for SciTE. I did not find anything beyond 2012-2014. And even less about the method for changing colors. All these .properties files contain color codes. Just find which one! lol
