GNOME's source viewer (Gedit and Builder) has code snippets plugin and builtin syntax highlighting specification but some are somewhat incomplete or lacking.
I know for python there is Gedi (Jedi) for autocompletion but I found that fidly to get working and I would rather no boxes pop-up over my work as I'm typing.

There are no code snippets for python 3 in Gedit there are a dozen Python 2 code snippets which can be transfered and they can work, so you don't need this

• Implementing Python full grammer through nested snippets
• Built-in function's snippet that try's to evaluate the values you put into the function if not provides comment with helpful info
• Authoring snippet to add a header that makes this
• Maybe som more features (please suggest)
• Fast Comprehensions lists and dict
• Fast selected text insertions to string, list, set
• Binary Sequence Generator
• I have one macro? called clamp that inserts a max and min nest maybe some more functions of that type

• Built-in Constant where f goes to False and t goes to True on tab and so on
• Built-in Type functions e.g. ". means string ]. means list and so forth
• Built-in Exceptions at minimum you can Write lowercase and get Camel-ed cased Exceptions
• Importable functions pre-packaged with python can be also be snippeted?

I have had a look at it, I'm not a web developer but I think it's handy if you can see all the attributes available to you in html context only. Meaning don't put in attributes that can be set/changed from CSS as that is what CSS is for. Also expand to every HTML5 tag instead of purly relying on div's and the id attribute.

• HTML tag snippets
• Complete tag attributes
• Authoring snippets
• Welcome to further suggestions

This lacks in a few areas but the first one that comes to mind is python's literal formating strings the {variable} area should be a different colour to the rest of the string. Not really important but when doing binary, octal or hex representations with 0b, 0o and 0x those prefix should also have a different style to rest of the number. Furthermore with dictionaries if you have a string for both key and value then the key string should be styled differently to assist readability. Built-in functions, types and classes get syntax highlighting why can user defined ones also get this? It might be a limintation of the spec but if not I will implement that.
