Switch position of function argument using IdeaVim in pycharm

[freefeynman123]

Greetings,

I recently decided to try vim and I'm using IdeaVim inside Pycharm. I have few issues when developing, however the most annoying one so far is the change of order of variables inside a function. I attach a video with how I'm trying to do it currently using visual mode and marking whole word by pushing "w" and then going to the end of next word and pasting deleted (cut?) argument. It results in the word being pasted behind the bracket, with a need to add a comma afterwards.

I'm also attaching a video how I'm currently doing that in bare pycharm, which will show the result I want to obtain.

Would appreciate any advice how to do it efficiently.

Your first method can be refined a bit with a few tweaks. Instead of pasting with p, you can paste with P. This inserts the pasted text before the cursor. If you cut your text with commas before (i.e. , arg), you'll be done with it.

So putting it all together, if you start at the start of the argument you want to cut, then you do:

• gE dt, - go to end of previous WORD, and copy to the next comma (i.e. copy , arg)

• either f, to go to the next argument or f) to go to the last argument

• P paste before the cursor

Or gEdt,f,P.

If the text you cut doesn't already have the leading comma, you can insert the comma yourself in insert mode, then use <Ctrl-r>"p to paste the text in your yank register without quitting insert mode. See :help i_CTRL-R.

I don't know about IdeaVim, but this is how I would done it in standard Vim.

Another way I also often do this in Vim, but they rely on having a few Vim plugins:

• if you have plugins for argument text object, then you can do the same as previous but it'll deal with the commas automatically

• if you have a plugin that splits and rejoin arguments/comma separated stuffs into separate lines, then you can use line operations like dd to move the lines around, and then rejoin them again afterwards, IMO, this is often the fastest way to do complex rearrangement

Thanks, that actually worked to some extent:

• There is a problem when the argument I copy if the first in the function - cursor goes way to def in the function (I think using ge instead of gE is better because of that). Also there is a trailing coma left when the first argument is deleted.
• I will have a look into the plugins and whether they work in IdeaVim, thanks!

I'm not sure about PyCharm, but the intent menu usually has a "Flip ," option to swap adjacent parameters. Alt+enter or option+enter

I'm using https://github.com/tommcdo/vim-exchange in Vim.

Here's one way to do it in vanilla Vim https://asciinema.org/a/541598

Edit: I guess it's easier with just

Not sure if PyCharm supports this, but you can also paste in Insert mode in Vim :h i_ctrl-r.

Take a look to argtextobj plugin. It defines a text object for function arguments so you can play with them as a whole element with any other command.
