INTRODUCTION *go-nvim*
go.nvim is a neovim plugin for the Go programming language. This is the
reference documentation.
Table of contents~
1. Motions |go-nvim-motions|
2. Text objects |go-nvim-text-objects|
3. Mappings |go-nvim-mappings|
4. Filetypes |go-nvim-filetypes|
5. Binaries |go-nvim-binaries|

7. Options |go-nvim-options|
==============================================================================
MOTIONS *go-nvim-motions*
*go-nvim-v_]]* *go-nvim-]]*
]] Go [count] top-level declarations forward. A top-level
declaration is a `func`, `type`, `var`, `const`, or `import`.
In |ft-gopresent| files it jumps [count] sections
forward
*go-nvim-v_[[* *go-nvim-[[*
[[ Go [count] top-level declarations backwards. In
|ft-gopresent| it jumps [count] sections backwards.
==============================================================================
TEXT OBJECTS *go-nvim-text-objects*
text objects is provided through treesitter text-objects plugin
*go-nvim-v_af* *go-nvim-af*
af "a function": complete function body and any preceding
documentation comment.
*go-nvim-v_if* *go-nvim-if*
if "inner function": function contents without the
signature.
*go-nvim-v_ac* *go-nvim-ac*
ac "a comment": the entire comment block, including the
comment characters themselves.
*go-nvim-v_ic* *go-nvim-ic*
ic "inner comment": content of the function but exclude
the start and end markers.
==============================================================================
MAPPINGS *go-nvim-mappings*
go.nvim does not provide default keymappings.
keymap in debug mode
c continue
n next
s step
o stepout
S cap S: stop debug
u up
D cap D: down
C cap C: run to cursor
b toggle breakpoint
P cap P: pause
p print, hover value (also in visual mode)
==============================================================================
FILETYPES *go-nvim-filetypes*
*ft-go*
go~
go files; default ft for go files
You need to set the |filetype| to `go` to run commands
provided by the pluginfor example: >
vim +'set ft=go' +GoSetup +'q!'
*ft-gomod*
gomod~
go.mod file; there are no options.
*ft-gotext* *ft-gohtml*
gotext gohtml~
text/template and html/template. Automatically applied
to files ending with the `.gotext` and `.gohtml`.
gohtml loads the standard html syntax highlighting,
but they are otherwise identical.
==============================================================================
BINARIES *go-nvim-binaries*
Several binary tools are supported;
go `go install`
gotest `go test`
golint `golangci-lint`
gotags
golines
goimport
settings below will take effect (so you'll need to use
`:Dispatch go build ./cmd/pkg`; the package name won't be added
automatically).
*go-nvim-compiler-go*
go ~
go.nvim using go to `go list` `go build` `go run` `go test`
*b:go-nvim_build_command*
Command to build Go code.
*go-nvim-compiler-gotest*
gotest~
with `go test`, `richgo`, or `ginkgo`
*go-nvim-compiler-golint*
golint~
with golangcl-lint
