After decades of using random editors and emacs I've switched to vim. So why not have a place to share a tip or bitch about weird things vim does (or fails to do)? Put short tips and discoveries under TIPS topic; for anything that warrants its own discussion, please start a new topic.
Q: Abbreviations, but only at beginning of line — I just wasted an hour searching for a way to create an iabbrev that triggers only at beggining of line. Say I want to convert a '===' to a '/*====================*/, but if and only if the === was typed at the start of its own line. Is that even possible?
Vim as an IDE — A combination of tmux and vim makes a minimal REPL IDE. I managed to cobble it together in a few minutes in spite of knowing nothing about vimscript and nearly nothing about tmux. My workflow is this: I open tmux and split it into at least two panes. The first one is where I run my Forth in, and according to tmux the pane is named '%0'. The second one is for vim. Now I need vim to send paragraphs of source into pane %0, as if they were typed. Tmux has a function 'send-keys'...
Kakoune - weird bindings I'm kind of trying to use kakoune, because I kind of like the idea of selecting then acting. But it's slow going, and I am not yet grokking it. I am also annoyed by the reliance on Alt-key combinations - the whole point of a modal editor is to use regular keys in normal mode...
Vim spirit — I've spent a few minutes with Kakoune (what a name) and Helix. Feels a bit like an infidelity, but it's really not. Each of these is not the 'vi', but it is a 'vi', the way my franken-forths are still Forths. Kak and hx get many things more right than vim: object/action order: the ability to select (and see the selection) first then act on the selection(s). It's really the right way to go about editing text, and there are many articles on the subject that do the argument more...
Off by 1 character — I hate that vim is always off by a character. Let me clarify. When you exit the insert mode, the cursor backs up to the last character entered. So if you insert some text, then delete to the end of the line, vim will eat your last-inserted character unless you move over one. Annoying, right? Or, say you repeatedly enter insert mode then exit back to command line. That is a no-op, right? Wrong: your cursor will move left one character. That seems kind of idiotic. Does...
Which config/plugins do you use for writing Gemtext? — I'm not really sure about, the only thing I set so far is that the text should wrap on the terminal border, but I want to set it to wrap at column 80. I don't know how you edit your gemtext files, are there any plugins, syntax highlighters or the like? Or is there even a dedicated editor for gemtext? Pls let me kno!
I want to have completion for my custom C language headers, but I cannot see how to add it. I use CoC and it does help with the language headers, but not the ones in my project folder. How can I add them?
The author and maintainer of Vim, Bram Molenaar, passed away today. Thank you, Bram, for such a wonderful program that has stood the test of time. :wq
Quitting VIM — Nothing new, but a quick review: [preformatted]
A long time ago I had the idea of changing vim keybinds such that each operation would have its dual as capital. most operations such as fF do this already. I wanted to do it for everything including movement. In the end it was too non standard given any reduction in complexity, didn't work for special characters, and it was unclear what dual meant (e.g. iI vs oO vs aA).
I wrote a plugin to use vim as a smallnet client frontend. You need a backend that formats things ok for it. Lynx works if you want web/gopher. I wrote a backend that supports gemini as well (and supports 10 gemini and 7 gopher types for input). It works pretty well so far. [https link] Plugin [https link] Custom Backend From the plugin folder run `make` and you are all set. The backend requires a go compiler (the plugin defaults to using lynx). For info on customization, get help in vim: [...
Editing Near-ASCII Binary Files — I am experimenting with a near-ASCII file format containing text messages and binary markers (high bit set). Vim is surprisingly useful: it will display files in a reasonable-for-debugging way by displaying hex values for high characters. It preserves these during editing, and will even allow you to enter non-ascii characters: In Insert mode, [preformatted] will insert 0xAB. o will similarly take 3 octal digits. Just numbers for decimal digits.
Configuration tricks, tips, etc.
What is the best way to write a plugin in Lua and C? — I wrote a plugin to use Vim as a hex editor. As there is quite a bit of computation to do I prefered not to do them in Vimscript. As the hex editor will manipulate arbitrary data and not text, Lua seemed a better choice than Python as the strings don't need to contain only Unicode characters. As some functions do heavy computation, I wrote them in C for the very substantial speed boost. Unfortunately, compiling the C librairy is not...
