Some Neovim tricks

[nvim]{.spurious-link target=”nvim”} [keymap]{.spurious-link target=”keymap”}¶

\< C-Y > scroll-up¶

\<C-U> scroll-down¶

`H`, `M`, `L` go to high/middle/low it should move to first non empty line¶

`d33|` `|` moves the cursor to the specified column in the current line¶

Find replace¶

`&` stands for the matched words¶

press `*` and do `:%s//xxx/` the search is omitted and it is the current selected word¶

Move around¶

`+` `-` can also be used to move to `+` Move to first none empty char of next line¶

`<CR>` can move to head of next line¶

word and WORD¶

The difference between words and WORDS is that the former only include letters, digits and numbers.¶

word can be a sequences of spaces. do `dw` inside a sequence of space and see what you get. w, b, e, ge are word motions.¶

`W` move on WORD boudnary. following are WORD `helloVimWord(){}`, `[1,2,3,4,5]` etc¶

`i` `a`; there is also `I` and `A` insert at begin of line and end of line¶

`Y` yank; it is same as `yy`; `P` past above¶

`s` and `S` was remapped in hop/leap. `s` -> `cl` `S` -> cc¶

**

`X` delete char left of cursor (\<BS> in norm mode)¶

command range and `g / v` command¶

`:.` current line¶

`:%` entire file¶

`$~last line¶

*** ~:12` line 12

`:12,14s/import/export/g` replace from line 12 to 14¶

`:.,.+12` from current line to current line + 12¶

`:.,$` from current line to eof¶

`:g/import/d` delete lines include `import`¶

`:g!/import/d` delete lines do NOT include `import` it same as `v` command `:v/import/d`¶

motion vs `/` command¶

all motion can be replace with find `/` command. e.g `dft` can also be `d/t<cr>`¶

delete¶

`d0` delete to begin of line¶

use `s` to delete¶

:%s/abc//<CR>
it can also write as :%s/abc<CR>

`db` backward delete word¶

`dvb` and `dve` delete `inclusive` ; `dvge`;¶

`das` `dap`¶

`dF*` search backward and delete¶

with surround `di` `ca` `da*` etc¶

`dh` delete 1 char to the left; `d3h` delete 3chars to the right¶

*

#vim_g¶

`g0` go to 0; same as `gg`¶

`ge` jump back end of word¶

`g&` it similar to macro, a command in Vim that repeats the last substitution (`:s`) command on all lines in the file. It's equivalent to `:%s//~/g`, where `//` reuses the last search pattern, and `~` reuses the last replacement string.¶

`gJ` join [cnt] lines `J`: join with remove indent, also works in visual mode¶

`gq` format text¶

wrap: `gj`, `gk` jump inside long lines , `g$`, `g^`¶

`g<C-A>` in visual mode/range, increase number of each line based on fist value in range. e.g. `1 1 1 1` -> `1 2 3 4`¶

`gu|U` + text obj capitalization, e.g. `gu$` `guW`, `guu` whole line, `gU3w`, `gufk` (lowcase to letter k)¶

`g~` similar to `gu|U`¶

`gv` re-select text¶

`g&` apply the replace changes to full document. It is helpful when you need to replace in one line and check if replace is correct and apply to full text¶

*

Search and replace¶

`%s/.$/&;/` `.$` match a none empty line `&~is what was matched¶

*** ~:v/^$/s/$/;`

:v inverse find /^$ is empty line
/s/$/; command of v; replace EOL to ;

`\ze`: `\ze` Zero-width ending split the search pattern into two, first half is match can be used later on, e.g. `end\ze(if|for)` match both `endif` and `endfor` but the matched pattern is `end` so `:s/\vend\ze(if|for)/&_/g` replace `endif` to `end_if`¶

`put=range(1,10)` add 1~10 to buffer¶

`<C-R>=` e.g. `<C-R>=range(1,10)` use register with value of expression¶

indentation¶

`v>` indent current line to the right¶

`>G` indent from current line the the end of file to the right¶

`=G` remove indent from current to eof¶

`>{` indent to right from begin of block to current line¶

`=` in visual mode, indent current line (based on context)¶

`>>` indent to the right with normal mode¶

Fugutive diff merge¶

reference `http://vimcasts.org/episodes/fugitive-vim-resolving-merge-conflicts-with-vimdiff/`¶

`Gdiff` are used to merge diff conflicts. You can also use `Gvdiffsplit!` It opens¶

left(the branch you used to work on, or local branch) . The buff is named as fugutive//2¶

middle the current working file,¶

right buffer which is the remote branch that you trying to merged into current branch (remote). the buffer named fugutive://3¶

If the cursor in middle buffer, `diffget //2` get changes from left file and use `]c` to jump to next merge conflict. and use `diffupdate` to refresh file¶

when done, use `only` to close other windows¶

You can use `diffput 1` to put changes throught. in fugutive, `dp` default alias to `diffput 1`¶

`Gwrite!`¶

Diffview¶

If git in merge status, `DiffViewOpen` will show the conflicts files¶

`<Leader>co|ct|cb|ca` select Ours, Theirs, Base and All or `dx` choose none¶
