A common process for me is to have a camelCased word that I wish to prepend to. I find the vanilla method a little too cumbersome as I will describe below. What I'm wondering is if there is a better method.

Example

function foo() {
  doSomething();
}

In this the doSomething is in camel case and I want to turn it into shouldDoSomething.

Things I've tried

Usually I will place the cursor at the beginning of the word and press ~hishouldEsc. However, this requires positioning the cursor correctly and performing a few operations one of which needs to be undone (~ move cursor to the right requiring an extra h).

I have also used tpope's vim-abolish Coercion by placing the cursor on the correct line and then Isomething_Esccrc. Unfortunatly the result of which is shouldDosomething not shouldDoSomething.

You can use s to delete the current letter and put you in insert mode.

sshouldD<esc>

This will let you delete the s insert shouldD yielding shouldDoSomething

Note: assuming you are on the d.

how about b g g U l i should Esc?

You can save that into a macro and re-use it if you need to do it a lot. Otherwise don't bother optimizing a task you only do once anyway.

EDIT:

If you want to make this a macro you can do qqbgUli<C-o>q to save it into the q register. Note that the macro would only be recorded as qqbgUli, since <C-o>q is what stops the recording without leaving insert mode.

You can also just map it to something like <C-i> or <leader>i if you use it often. map <leader>ic bgUli (ic as in Insert preserving Camel-case)

  • Isn’t that the same thing as ~? Haven’t really gained much. Though the macro idea is nice. – Sukima Nov 7 '17 at 23:44
  • Would the <Ctrl-o>q cause the second run of the macro to start recording again? Seems like :let @q = “bgUi” work better? – Sukima Nov 7 '17 at 23:50
  • ~ toggles case, which is faster, but gU sets uppercase, which is more accurately what you want. Using let should also work, but the <Ctrl-o>q is what stops recording the macro i the first place without leaving insert mode so you can then type the word (assuming it's not always the same, "should") – DarkWiiPlayer Nov 8 '17 at 7:07
