vim-markdown

  • ge (format a table)
    • when the table contains code with a pipe symbol “|” this won’t work, but you can use the following workaround:
      • first escape all pipe symbols with a backslash \, but not the |-symbols of the table
      • format the table with ge
      • manually remove all \ again
    • this works only if all rows of the table start with a “|“-symbol
      • you can run something like :%s/\(^`.*`\s|\)/| \1/g to reformat all tables in your markdown files, so that ge works

Diagnostics

  • definition in neovim doc
    • “Nvim provides a framework for displaying errors or warnings from external tools, otherwise known as “diagnostics”. These diagnostics can come from a variety of sources, such as linters or LSP servers. The diagnostic framework is an extension to existing error handling functionality such as the quickfix list.”
  • leadere (open floating diagnostic message, useful if you cannot read the inline message)

Formatter

  • list
    • markdown: prettier.formatfile
    • lua: :Format (LSP format buffer)
    • cpp: :ClangFormat (rhysd/vim-clang-format)
  • TODO: install conform.nvim
  • leaderjkey-for-language
  • available formatters:
    • :ClangFormat
    • coc-prettier, github
      • typical workflow:
        • To install prettier in your project and pin its version as recommended, run: npm install prettier -D --save-exact
        • Then, create an empty config file to let editors and other tools know you are using Prettier: node --eval "fs.writeFileSync('.prettierrc','{}\n')"
        • Next, create a .prettierignore file to let the Prettier CLI and editors know which files to not format. Here’s an example: node --eval "fs.writeFileSync('.prettierignore','# Ignore artifacts:\nbuild\ncoverage\n')"
        • Now, format all files with Prettier: npx prettier . --write
          • prettier --write . is great for formatting everything, but for a big project it might take a little while. You may run prettier --write app/ to format a certain directory, or prettier --write app/components/Button.js to format a certain file.
    • :Format, alias for vim.lsp.buf.format() (defined in init.lua)

clang, clangd

  • clang is the compiler
  • clangd is the language server

clang

compile commands json

  • From :LspInfo → press tab:
    • If compile_commands.json lives in a build directory, you should symlink it to the root of your source tree. ln -s /path/to/myproject/build/compile_commands.json /path/to/myproject/

compile flags txt

  • doc
  • run :LspRestart to reload
    • or: run :e to reload
  • for simple projects (eg. compile one file only):
    • create a compile_flags.txt
      • in the folder where the source code is
      • eg. with the content -std=c++20

Example compile_flags.txt:

-nostdlibinc
-I/home/bra-ket/osbook/devenv/x86_64-elf/include

autocomplete, completion

  • see also Help Code, Doc
  • 3 popup/drop-down Arten:
    • vim builtin completion (sieht so aus wie completionVorschlag1)
    • coc.nvim (sieht so aus wie completionVorschlag1 [A])
    • nvim-cmp (sieht so aus wie completionVorschlag1 Variable)
  • ctrl y (confirm + replace)
  • ctrl e (discard + do not do anything)
    • helpful eg. if two conflicting completion popups appear at the same time, ctrl e will switch between these

vim builtin completion

  • ctrl n (next suggestion)
  • ctrl p (previous suggestion)
  • ctrl x followed by ctrl f (Path completion)
    • select with ctrl n then press ctrl x followed by ctrl f again to select the next subfolder etc.

nvim-cmp, LuaSnip, friendly-snippets

  • das completion popup mit den Kategorien (Variable, Function, Keyword, usw) in der rechten Spalte (zB completionVorschlag1 Variable, completionVorschlag2 Keyword, completionVorschlag2 Function, usw) wird von nvim-cmp erzeugt
  • servers must be added to the LSP server list local servers = {} in init.lua, otherwise nvim-cmp will not autocomplete
  • luasnip (snippet engine)
    • :LuaSnipListAvailable
    • nvim-cmp requires a snippet engine
    • tab, shifttab
      • select item in drop-down
        • if the item is a function a snippet is inserted
      • edit next/previous function parameter in the function snippet
    • luasnip config: Example-mappings#luasnip
    • TODO:
  • friendly-snippets (snippet collection)
  • nvim-cmp steuert scrolling im “documentation preview” popup
    • press ctrl f to scroll down
    • alle key mappings in .config/nvim/init.lua bei cmp.setup { ..., mapping = ... }
    • problem: you cannot jump into the documentation preview window in nvim-cmp (which is important to open links in the documentation preview window, eg. MDN links for JavaScript)
      • solution: instead, you can first autocomplete an expression and then press ctrl k or shift k while the cursor is on the completed expression

friendly-snippets

important: Each language has its own Wiki page where you can find all keymaps to trigger the snippets.

Other Tricks:

How to type the following code?:

<div className='wrapper'>
  |
</div>
  • steps:
    • press j and select the “jsx element” snippet
    • write div into the first jsx tag and press Esc (or jj)
      • this will write another div into the second jsx tag while the cursor remains in its current position
    • press a and write classN, then press tab to select className?~ Field, press Enter on className?~ Field
      • this will put a className='|' attribute into the first jsx tag with the cursor positioned in between the single quotes (where the vertical bar | is)
    • write wrapper
    • after typing the last r of wrapper press ctrlo and then j
      • this will place the cursor in the middle line between the first and second jsx tag (where the vertical bar | is) in insert mode
      • you can press ctrloj even after just typing wra, pressing tab and selecting wrapper and before pressing Enter on wrapper in the popup (ie. once you select wrapper, the completed word wrapper will not disappear when you press ctrloj)

coc.nvim

  • das completion popup mit den eckigen Klammer Symbolen in der rechten Spalte (zB completionVorschlag1 [A], completionVorschlag2 [B], usw) wird von coc.nvim erzeugt, wobei jedes eckige Klammer Symbol für jeweils eine “source” steht, die in :CocList → “sources” registriert wurde
    • am besten alle “sources” deregistrieren (über :CocList → “sources”), weil sonst der nvim-cmp popup und der coc.nvim popup manchmal gleichzeitig erscheinen
    • wobei das source namens File nützlich ist (zeigt die files in cwd, wenn man ./ typet)
  • :CocList (select “sources” to configure which sources are used for autocompletion)
  • :CocConfig (opens coc-settings.json where you can configure Coc, eg. you can turn off Coc’s autocompletion by adding "suggest.autoTrigger": "none" to coc-settings.json)

nvim-tree

  • tricks:
  • P (parent directory)
    • Ptab (collapse parent)
  • f somepattern (filter the tree)
  • - (show more (show parent folder))
  • ctrl] (show less (only show the folder on which the cursor is placed, ie. this works only if the cursor is placed on a folder))
  • c then p (duplicate file, automatically shows “rename” where you have to choose a new name)
  • for Firefox-Bookmarks-like behavior use
    • init.lua: on_attach keymap: bind ctrle to api.tree.toggle
    • keymaps.lua: normal keymap: bind ctrle to :NvimTreeFocus
  • alth, altl (focus/unfocus nvim-tree, when nvim-tree open)
  • a then put a “/” at the end of the written name (create dir)
  • J (jump to last item in folder)
  • K (jump to first item in folder)
  • i (show gitignored folders and files)
  • U (show hidden folders and files)
  • q (quit)
  • statt netrw
  • / (search)
  • ctrld (collapse)
  • gy (get absolute path)
  • Y (get relative path)

toggleterm (for lazygit integration in nvim)

  • enter terminal mode: press i
  • scroll (= enter normal mode)
    • ctrl\ ctrln to exit terminal mode, then you can use vim motions to move around
    • scroll with mouse first and then you can use pageUp/pageDown
    • press i to enter terminal mode again
  • written in lua
  • better than floaterm (written in vimscript)
  • 1ctrl\, 2ctrl\, 7ctrl\, etc. to create and access terminals
    • the prefixed number is the number of the terminal instance
    • pressing a non-existent number will create a new terminal

git

gitsigns

This plugin is only active in git-tracked folders. Ie. :map (and, therefore, space sk) will not show any keymaps related to gitsigns in non-git-tracked folders.

  • alt , (next hunk)
  • alt . (prev hunk)
  • space h b (blame line)
    • um schnell herauszufinden in welchem commit die line geaddet wurde
    • press the keymap twice to jump into the preview window (useful if you want to copy the commit hash in the preview window in order to see the whole commit)
  • diff
    • space h d (diff zu letztem commit)
    • space h D (diff zu vorletztem commit)
    • better use fugitive: space g f (see fugitive)

lazygit

  • meaning of keymaps (official doc)
  • altenter (when writing a commit message: starts a new line)
  • when lazygit spins up the external hard drive so that lazygit lags, open nvim ~/.config/lazygit/state.yml and run :g/^-\ \/media/d to remove all “recent repo” paths to a git repo on the external hard drive
  • start lazygit
    • space gg (for normal repos)
    • space gd (for dotfiles repo)
  • each panel has its own help menu!
  • commands that work in all panels
    • R (Refresh the git state (i.e. run git status, git branch, etc in background to update the contents of panels). This does not run git fetch.)
      • does not work in the “branches” panel because “rename branch” is also mapped to R
    • W (groß W, diff menu)
    • ctrl r (switch repo)
      • does not work when a commit is selected during cherry-picking (see commands under “commits” panel)
    • @ (focus command log)
    • x (help) (ins commit panel und auf x drücken, zeigt zB amend, reset, etc.)
    • H, L (scroll left, right)
      • praktisch um kleine panels zu lesen, e.g. “commit” panel

    • esc (go back to commit list after seeing a commit’s files)
    • pageup/pagedown to scroll the main panel
    • ctrl -/+ (zoom out/in, very useful to view the full main panel)
      • better: press enter on the file in the “files” panel, then press + to rotate to the view where the file spans the full width of the screen
  • in “files” panel
    • d (git checkout, to discard changes made to a file)
    • A (amend)
      • erst space und dann A
  • in “commits” panel
    • ctrls (show commits for a specific file only)
      • when you want to see the commits of a deleted file you have to checkout one of the commits before the commit where the file was deleted, then ctrls will work for this file (when you are done, you can checkout master in the “branches” panel to get back the latest commits)
    • / (search commits, Warning: if a commit message has more than one line the search will only search in the first line of the commit message, doc)
    • + (view awesome commit graph, or just to make the commit messages more readable)
    • ctrlo (copy commit SHA to clipboard; useful eg. when writing commit messages that refer to other commits)
    • um mehr vom file zu sehen:
      • im “Commits” panel den commit fokussieren (aber nicht enter drücken) und dann mehrmals \} drücken, sodass am Ende der ganze file sichtbar ist

  • commit
    • c
  • push

  • :G <tab><tab> to see available commands
  • :G log
  • :G shortlog
  • :Gdiffsplit HEAD~1 (horizontal view)
  • :Gvdiffsplit HEAD~1 (vertical view)
    • space g f

  • :h (telescope.mappings)
  • ctrl/ (in insert mode), ? (in normal mode) (show shortcuts)
  • spacespace (recent files)
    • based on :oldfiles (:h :o)
      • eg. you can filter the :oldfiles list using :filter pattern o (where :o is the short version of :oldfiles, see :h :o)
    • to remove entries in :oldfiles edit the “ShaDa” file using nvim nvim .local/state/nvim/shada/main.shada (see vi.stackexchange)
      • eg. you can install michaeljsmith/vim-indent-object and then use :g/pattern/norm dai
      • note: nvim has a different :oldfiles system than vim (see vi.stackexchange)
      • useful if you accidentally put some files in the :oldfiles list that are on an external hard drive (the hard drive has to spin up each time you press this telescope shortcut while the frozen telescope window is blocking nvim)
        • in this case you can run :g/\/media\/bra-ket\/INTENSO\//norm dai to clear the :oldfiles list from all entries that are causing this behavior
  • ignoring files (comment):
    • put them in .ignore
    • use the file_ignore_patterns telescope option (:h telescope.defaults.file_ignore_patterns)
    • use .gitignore
  • ctrlt (open file in new tab)
  • ctrl-/+ (see more of the preview pane/results pane)
  • ctrlu, ctrld (scroll preview up/down)
  • spacesk (search keymaps of active plugins, ie keymaps of inactive plugins are not shown)
  • spacesa (search autocommands, my own custom autocommands have a ph_ prefix in their augroup so that I can find them more easily in telescope or via :autocmd ph_<tab>)
    • what is augroup?
    • better: use :autocmd ph_<tab> to find autocommands and their doc (specified in the desc = "..." field of nvim_create_autocmd)
  • space? (recently opened)
  • space/ (current buffer find)

treesitter

(note: treesitter highlighting is distinct from the LSP-based “semantic highlighting”)

  • :set ft=markdown (enable syntax highlighting for unwritten buffer, ie a “No name” buffer)
  • from supported-languages
    • to support a specific feature for a specific language requires both
      • a parser for that language and
      • an appropriate language-specific query file for that feature
    • :TSInstall parserName (install a specific parser)
      • in use: markdown, markdown_inline
    • :TSInstallInfo (list all installed parsers)

    • ctrlb (fast markdown section select)

Vista (Aerial ist besser!)

  • Vista: in “:h Vista”: tag: vista-key-mappings
  • q (quit)
  • p (preview)

vim illuminate

auto-session

  • while in the session-lens telescope picker:
    • c-s restores the previously opened session. This can give you a nice flow if you’re constantly switching between two projects.
    • c-d will delete the currently highlighted session. This makes it easy to keep the session list clean.
  • space cs (save session)

nvim Profiling

reddit.com

Try run nvim with nvim -u NONE. Is it still slow?

Try profiling when inside that file.

:profile start profile.log
:profile func *
:profile file *.

Now start doing what is slow

:profile pause.

Quit vim and open profile.log.

At the end you should see sum of functions exec times and count of usage. Should point you.

bot summon :help profile
