Subversive provides two new operator motions to make it very easy to perform quick substitutions. It contains no default mappings and will have no effect until you add your own maps to it.
SUBSTITUTE MOTION 'subversive-substitute-motion'
" s for substitute
nmap s <plug>(SubversiveSubstitute)
nmap ss <plug>(SubversiveSubstituteLine)
nmap S <plug>(SubversiveSubstituteToEndOfLine)
Note that in this case you will be shadowing the change character key 's' so you will have to use the longer form 'cl'
After adding these maps, you can then execute 's<motion>' to substitute the text object provided by the motion with the contents of the default register (or an explicit register if provided). For example, you could execute `siw` to replace the current word under the cursor with the current yank, or `sip` to replace the paragraph, etc.
SUBSTITUTE OVER RANGE MOTION 'subversive-substitute-over-range-motion'
Another interesting operator provided by subversive allows specifying both the text to replace and the line range over which to apply the change by using multiple consecutive motions.
nmap <leader>s <plug>(SubversiveSubstituteRange)
xmap <leader>s <plug>(SubversiveSubstituteRange)
nmap <leader>ss <plug>(SubversiveSubstituteWordRange)
After adding this map, if you execute '<leader>s<motion1><motion2>' then enter some text into a prompt in the status bar, then the text given by 'motion1' should be replaced by the text we entered in the prompt for each line provided by 'motion2'. Alternatively, we can also select 'motion1' in visual mode and then hit '<leader>s<motion2>' for the same effect.
This can be very powerful. For example, you could execute '<leader>siwip' to replace all instances of the current word under the cursor that exist within the paragraph under the cursor. Or '<leader>sl_' to replace all instances of the character under the cursor on the current line.
The '<leader>ss' mapping is used as a shortcut to replace the current word under the cursor. This allows you for example to execute '<leader>ssip' to replace the word under cursor in the current paragraph. Note that this matches complete words so is different from '<leader>siwip' (which will not require that there be word boundaries on each match)
See here for an example: https://i.imgur.com/0qh2sOU.gif
In this gif, we first rename the local 'foo' parameter by executing '<leader>ssom' then entering 'bar' in the prompt (note that 'om' is a custom motion that stands for 'outer c# method' and is not provided by this plugin). Also note that because we are using '<leader>ss', the text '_foos' is unaffected because it does not match the complete word. It is useful in this case because we only want to rename the parameter within the function.
After that we switch to visual mode and select the 'foo' part '_foos' then execute '<leader>sie' and once again enter 'bar' into the prompt. `ie` is again a custom motion that stands for `entire buffer` (see next section for details)
After that we move to the 'Foo' part of 'AddFoo' and execute '<leader>seie' and once again enter 'Bar'. Then finally do the same for the fully capitalized 'FOOS'.
CUSTOM TEXT OBJECTS
Note that to really take advantage of these mappings, it is helpful to add custom text objects in addition to just the built-in ones like current paragraph ('ip'), current sentence ('is'), or current line ('_'). Custom text objects such as current indent level, current method, current class, entire buffer, current scroll page, etc. can all help a lot here.
For example, a couple really simple motions that are useful for subversive are:
" ie = inner entire buffer
onoremap ie :exec "normal! ggVG"<cr>
" iv = current viewable text in the buffer
onoremap iv :exec "normal! HVL"<cr>
"What if I don't want to use the prompt and want to directly replace with a register value?"
If you provide an explicit register to any of the substitute motions above it will not prompt and instead will use the contents of the given register. For example, '"a<leader>siwip' will immediately replace all instances of the current word under the cursor with the contents of register 'a' that exist within the current paragraph.
If this isn't enough, you can also use the following plugs instead:
nmap <leader>s <plug>(SubversiveSubstituteRangeNoPrompt)
xmap <leader>s <plug>(SubversiveSubstituteRangeNoPrompt)
nmap <leader>ss <plug>(SubversiveSubstituteWordRangeNoPrompt)
Which will work identically to the previous plugs except instead of prompting it will use the default register.
CONFIRMING EACH SUBSTITUTION 'subversive-confirming'
For many substitutions, you can rely on the highlight preview to understand what is being replaced. But if you are doing a larger replacement across the entire file you might want to confirm each one. You can do this with the following maps:
nmap <leader>cr <plug>(SubversiveSubstituteRangeConfirm)
xmap <leader>cr <plug>(SubversiveSubstituteRangeConfirm)
nmap <leader>crr <plug>(SubversiveSubstituteWordRangeConfirm)
These work the same as the '<leader>r' maps above except will step through each replacement one by one.
SUBVERSIVE SETTINGS 'subversive-settings'
'g:subversivePromptWithCurrent' - When set to '1', the prompt will include the text that is being replaced. This can be useful if you want to just make an edit to it. Default: '0'
'g:subversiveCurrentTextRegister' - When set, the given register will be populated with the text that is being replaced. This can be useful as an alternative to 'g:subversivePromptWithCurrent', so that you can hit '<c-r>r' in the prompt (assuming you set it to 'r') when you want to edit it and otherwise just directly type when you want to do a full replace.
ABOLISH INTEGRATION 'subversive-abolish-integration'
If you have also installed vim-abolish (https://github.com/tpope/vim-abolish), then you might consider adding something similar to the following mapping as well:
nmap <leader><leader>s <plug>(SubversiveSubvertRange)
xmap <leader><leader>s <plug>(SubversiveSubvertRange)
nmap <leader><leader>ss <plug>(SubversiveSubvertWordRange)
This will behave the same as '<leader>s' except that it will perform an abolish 'subvert' instead of using vim's built in substitute command. This will apply the substitution and also preserve whatever case the original word has. For example:
See here for an example: https://i.imgur.com/qMfYjBD.gif
In this example, we move the cursor overtop 'foo' and then execute '<leader><leader>seie' then enter 'bar', which replaces all instances of 'foo' regardless of case.
This can be a very convenient way to perform quick renames.
As you would expect, the '<leader><leader>ss' mapping works similarly except only matches complete words that include word boundaries.
And once again there are also alternative plugs that will use default register instead of a prompt if you prefer that:
nmap <leader><leader>s <plug>(SubversiveSubvertRangeNoPrompt)
xmap <leader><leader>s <plug>(SubversiveSubvertRangeNoPrompt)
nmap <leader><leader>ss <plug>(SubversiveSubvertWordRangeNoPrompt)
YOINK INTEGRATION 'subversive-yoink-integration'
Note that if you install vim-yoink (https://github.com/svermeulen/vim-yoink) alongside vim-subversive, then the post-paste yoink swapping feature will automatically work with subversive (single motion) substitutions as well. In other words, assuming the default mappings, you can execute 'siw' then hit '<c-n>' / '<c-p>' to swap between different yanks from the yoink history.
Subversive also provides a plug to replace visual mode paste to provide post paste swapping there as well:
xmap s <plug>(SubversiveSubstitute)
xmap p <plug>(SubversiveSubstitute)
xmap P <plug>(SubversiveSubstitute)
Now if you hit 'p' while in visual mode you can swap between yanks just like when pasting in normal mode.
