I'm looking for an editor I can easily add to or change rules for syntax highlighting
 

I'm using Atom on an Ubuntu based system and almost love it.

However, I want to change the syntax highlighting rules without having to dig into Atom. Atom's looks to be amazingly powerfully and flexibly customizable, but it's far too much for me.

What I most want to do is control the colors for individual things like, for example, /****comments***/ and I'd like to have it recognize variable type names by more than just the underscore-t at the end. My initials are dk, so I'd like to name my variable types with an underscore-d-k.

exmpletypename_dk

And have them highlit with the same, or a similar color to underscore-t type names.

That's the total extent of the changes I want to make. So Atom seems overkill for my purposes.

Sorry for the rambling nature of this post. I'm just fuzzy this morning.

jEdit is really awesome, i love it

Should GTK be added here? If not where on this site should I look?

I would add Notepad++, which is a very good open source programming editor for Windows.

Shouldn't this list be put into the LQ Wiki? So many dead links by now.

I hear this was a good Linux alternative?

Yes, it (somehow) is.

Geany!!! This is my all-time favorite - Multi-platform, you can edit the syntax highlight color schema, easy to use and learn - lots of cool plugins ( I wrote a BASH script that tidies my BASH scripts even!) Supports a whole bunch of programming languages...

I love it!

Geany, a small and fast IDE

It is well maintained and updated actively.

theide - most productive ide of them all
 

Not in the list, and the ide I use constantly:
theide

Back when I was searching for a good ide, I have tried most of those in the sticky-list
but most fell short for some or all of the following reasons:
- non-intuitive-ui,
- failure to implement 'standard' features,
- complex coding requirements for simple concepts,
- platform restrictions,
- strange & complex project structures,
- unclear/slow/dead updates & developing (of the ide itself)
- + .. + .. + ..

and I always came back to theide. It is now my main dev-tool for all platforms/OS's.
It takes about half-a-day to find your feet & then you'll wonder why you wasted
your time with any of the others.

List of Free Software and Freeware IDEs
 

MinIDE link looks broken. or at least it went to the wrong place for me.

Not surprising considering that the OP is 13 years old.

Maybe $SEARCH_ENGINE is your friend?

That's why I suggested to make a wiki out of this.

Do it.
