Force overtype (rather than insert) key behaviour, block newline entry, delete and backspace

[pachpict]

(This is all part of a project to use Micro to create a 'typewriter' mode for the Canute Console Braille display, referenced here: #2973.)

Could I have some advice about how to force micro to do several things related to key entry?

1. Start micro with the assumption that the insert key has been pressed so it starts overwriting? (I'm not bothered either way if the user can 'flip' this by pressing the insert key or if its locked into overtype mode).
2. Block newline entry with the enter key, delete or backspace. Alternatively could remap behaviour so enter is mapped to replicate down arrow behaviour, delete to right arrow, backspace to left arrow.

I appreciate that there will remain other ways of the user forcing text inserted (pasting), or deleting (using ctrl+k) and so on. That's OK for now, this is a prototype.

Thank you for your help, Micro continues to open up wonderful opportunities with the Canute display.

Hi,

Start micro with the assumption that the insert key has been pressed so it starts overwriting?

Not sure how to do this.

• Micro does not have a Sendkey() function exposed for Lua scripting.
• I cannot find an insert/overtype setting.
• Perhaps you could do this in the operating system before launching micro?

Remap behavior so enter is mapped to replicate down arrow behavior, delete to right arrow, backspace to left arrow.

Add the following to your bindings.json file:

    "Enter":           "CursorDown",
    "Delete":          "CursorRight",
    "Backspace":       "CursorLeft",

You may/may-not also have to make these assignments in a sub section for the command line:

"command": {
    "Enter":           "CursorDown",
    "Delete":          "CursorRight",
    "Backspace":       "CursorLeft",
},

Kind Regards Gavin Holt

Adding the following to init.lua should work:

function onBufPaneOpen(bp)
    bp:ToggleOverwriteMode()
end

That's great, thank you.

@pachpict, one of the answers by @Gavin-Holt or @dmaluka should be marked as an answer. Or maybe there should be a merged one.
