INTRO *go-intro*
Go (golang) support for Vim. vim-go comes with sensible predefined settings
(e.g. automatic `gofmt` on save), has autocomplete, snippet support, improved
syntax highlighting, go toolchain commands, etc. It is highly customizable,
and individual features can be toggled easily. vim-go leverages a number of
tools developed by the Go community to provide a seamless Vim experience.
* Compile your package with |:GoBuild|, install it with |:GoInstall| or
test it with |:GoTest|. Run a single test with |:GoTestFunc|).
* Quickly execute your current file(s) with |:GoRun|.
* Improved syntax highlighting and folding.
* Debug programs with integrated `delve` support with |:GoDebugStart|.
* Completion support via `gocode`.
* `gofmt` or `goimports` on save keeps the cursor position and undo history.
* Go to symbol/declaration with |:GoDef|.
* Look up documentation with |:GoDoc| or |:GoDocBrowser|.
* Easily import packages via |:GoImport|, remove them via |:GoDrop|.
* Precise type-safe renaming of identifiers with |:GoRename|.
* See which code is covered by tests with |:GoCoverage|.
* Add or remove tags on struct fields with |:GoAddTags| and |:GoRemoveTags|.
* Call `gometalinter` with |:GoMetaLinter| to invoke all possible linters
(`golint`, `vet`, `errcheck`, `deadcode`, etc.) and put the result in the
quickfix or location list.
* Lint your code with |:GoLint|, run your code through |:GoVet| to catch
static errors, or make sure errors are checked with |:GoErrCheck|.
* Advanced source analysis tools utilizing `guru`, such as |:GoImplements|,
|:GoCallees|, and |:GoReferrers|.
* Automatic `GOPATH` detection which works with `gb` and `godep`. Change or
display `GOPATH` with |:GoPath|.
* Integrated and improved snippets, supporting `ultisnips`, `neosnippet`,
and `vim-minisnip`.
* Share your current code to play.golang.org with |:GoPlay|.
* On-the-fly information about the word under the cursor. Plug it into your
custom Vim function.
* Text objects such as "a function" (|go-af|) or "inner function" (|go-if|).
* Most commands are run asynchronous in Neovim and Vim 8. Fully async
building and testing.
* Integrated with the Neovim terminal, launch |:GoRun| and other Go commands
in a terminal buffer.
* Switch between `file.go` and `file_test.go` code with |:GoAlternate|.
* Supports integration with the Tagbar and ctrlp.vim plugins.
* ...and more...
==============================================================================
INSTALL *go-install*
The latest stable release, https://github.com/fatih/vim-go/releases/latest, is
the recommended version to use. If you choose to use the master branch
instead, please do so with caution; it is a _development_ branch.
vim-go follows the standard runtime path structure and should work with any of
the major plugin managers.
For Pathogen or Vim |packages|, just clone the repo. For other plugin managers
you may also need to add the lines to your vimrc to execute the plugin
manager's install command.
* Vim 8 |packages|

Plugin 'fatih/vim-go', { 'do': ':GoUpdateBinaries' }
<
* Manual (not recommended) >
Copy all of the files into your `~/.vim` directory
<
You will also need to install all the necessary binaries. vim-go makes it easy
to install all of them by providing a command, |:GoInstallBinaries|, to
`go get` all the required binaries. The binaries will be installed to $GOBIN
or $GOPATH/bin (default: $HOME/go/bin). It requires `git`.
Depending on your installation method, you may have to generate the plugin's
|:helptags| manually (e.g. `:helptags ALL`).
Autocompletion is enabled by default via 'omnifunc', which you can trigger
with |i_CTRL-X_CTRL-O| (`<C-x><C-o>`).

==============================================================================
COMMANDS *go-commands*
*:GoReportGitHubIssue*
:GoReportGitHubIssue
GoReportGitHubIssue opens the default browser and starts a new bug report
with useful system information.
*:GoPath*
:GoPath [path]
GoPath sets and overrides GOPATH with the given {path}. If no {path} is
given it shows the current GOPATH. If `""` is given as path, it clears
current `GOPATH` which was set with |:GoPath| and restores `GOPATH` back
to the initial value which was sourced when Vim was started.
*:GoImport*
:GoImport[!] [path]
Import ensures that the provided package {path} is imported in the current
Go buffer, using proper style and ordering. If {path} is already being
imported, an error will be displayed and the buffer will be untouched.
If [!] is given it will download the package with `go get`
*:GoImportAs*
:GoImportAs [localname] [path]
Same as Import, but uses a custom local name for the package.
*:GoDrop*
:GoDrop [path]
Remove the import line for the provided package {path}, if present in the
current Go buffer. If {path} is not being imported, an error will be
displayed and the buffer will be untouched.
*:GoLint*
:GoLint [packages]
Run golint for the directory under your current file, or for the given
packages.
*:GoDoc*
:GoDoc [word]
Open the relevant GoDoc in split window for either the word[s] passed to
the command or by default, the word under the cursor.
*:GoDocBrowser*
:GoDocBrowser [word]
Open the relevant GoDoc in browser for either the word[s] passed to the
command or by default, the word under the cursor. By default it opens the
documentation in 'https://godoc.org'. To change it see |'g:go_doc_url'|.
*:GoFmt*
:GoFmt
Filter the current Go buffer through gofmt. It tries to preserve cursor
position and avoids replacing the buffer with stderr output.
*:GoImports*
:GoImports
Filter the current Go buffer through goimports (needs to be installed).
`goimports` automatically discards/add import path based on the code. Like
|:GoFmt|, It tries to preserve cursor position and avoids replacing the
buffer with stderr output.
*:GoPlay*
:[range]GoPlay
Share snippet to play.golang.org. If no [range] is given it shares
the whole file, otherwise the selected lines are shared. Snippet URL
is copied to system clipboard if Vim is compiled with 'clipboard' or
'xterm-clipboard' otherwise it's get yanked into the `""` register.
*:GoVet*
:GoVet[!] [options]
Run `go vet` for the directory under your current file. Vet examines Go
source code and reports suspicious constructs, such as Printf calls whose
arguments do not align with the format string. Vet uses heuristics that do
not guarantee all reports are genuine problems, but it can find errors not
caught by the compilers.
You may optionally pass any valid go tool vet flags/options. In this case,
`go tool vet` is run in place of `go vet`. For a full list please see
`go tool vet -h`.
If [!] is not given the first error is jumped to.
*:GoDef*
:GoDef
gd
CTRL-]
g<C-LeftMouse>
<C-LeftMouse>
Goto declaration/definition for the declaration under the cursor. By
default the CTRL-] shortcut, the mapping `gd` and <C-LeftMouse>,
g<LeftMouse> are enabled to invoke :GoDef for the identifier under the
cursor. See |'g:go_def_mapping_enabled'| to disable them. No explicit
arguments are supported.
vim-go also keeps a per-window location stack, roughly analogous to how
Vim's internal |tags| functionality works. This is pushed to every time a
jump is made using the GoDef functionality. In essence, this is a LIFO
list of file locations you have visited with :GoDef that is retained to
help you navigate software.
*:GoDefStack*
:GoDefStack [number]
This command Jumps to a given location in the jumpstack, retaining all
other entries. Jumps to non-existent entries will print an informative
message, but are otherwise a noop.
If no argument is given, it will print out an interactive list of all
items in the stack. Its output looks like this:
1 /path/first/file.go|1187 col 16|AddThing func(t *Thing)
> 2 /path/thing/thing.go|624 col 19|String() string
3 /path/thing/thing.go|744 col 6|func Sprintln(a ...interface{}) string
This list shows the identifiers that you jumped to and the file and cursor
position before that jump. The older jumps are at the top, the newer at
the bottom.
The '>' points to the active entry. This entry and any newer entries
below it will be replaced if |:GoDef| is done from this location. The
CTRL-t and |:GoDefPop| command will jump to the position above the active
entry.
Jumps to non-existent entries will print an informative message, but are
otherwise a noop.
*:GoDefStackClear*
:GoDefStackClear
Clears the current stack list and resets it.
*:GoDefPop*
:GoDefPop [count]
CTRL-t
Navigate to the [count] earlier entry in the jump stack, retaining the
newer entries. If no argument is given, it will jump to the next most
recent entry (`:GoDefPop 1`). If [count] is greater than the number of
prior entries, an error will be printed and no jump will be performed.
If you have used :GoDefPop to jump to an earlier location, and you issue
another :GoDef command, the current entry will be replaced, and all newer
entries will be removed, effectively resuming the stack at that location.
By default [count]CTRL-t is enabled to invoke :GoDefPop. Similarly,
hitting CTRL-t without a prior count is equivalent to `:GoDefPop 1`. See
|'g:go_def_mapping_enabled'| to disable this.
*:GoRun*
:GoRun[!] [expand]
Build and run your current main package. By default all main files for the
current file is used. If an argument is passed, [expand] is used as file
selector. For example use `:GoRun %` to select the current file only.
You may optionally pass any valid go run flags/options. For a full list
please see `go help run`.
If [!] is not given the first error is jumped to.
If using neovim then `:GoRun` will run in a new terminal according to
|'g:go_term_mode'|.
*:GoBuild*
:GoBuild[!] [expand]
Build your package with `go build`. Errors are populated in the quickfix
window. It automatically builds only the files that depends on the current
file. `:GoBuild` doesn't produce a result file.

You may optionally pass any valid go build flags/options. For a full list
please see `go help build`. Options are expanded with [expand].
If [!] is not given the first error is jumped to.
If using neovim then this command is fully async, it does not block the
UI.
*:GoGenerate*
:GoGenerate[!] [expand]
Creates or updates your auto-generated source files by running `go
generate`.
You may optionally pass any valid go generate flags/options. For a full
list please see `go help generate`. Options are expanded with [expand].
If [!] is not given the first error is jumped to.
*:GoInfo*
:GoInfo
Show type information about the identifier under the cursor. For example
putting it above a function call is going to show the full function
signature. By default it uses `gocode` to get the type informations. To
change the underlying tool from `gocode` to another tool, see
|'g:go_info_mode'|.
*:GoInstall*
:GoInstall[!] [options]
Install your package with `go install`.
You may optionally pass any valid go install flags/options. For a full
list please see `go help install`.
If [!] is not given the first error is jumped to.
*:GoTest*
:GoTest[!] [expand]
Run the tests on your _test.go files via in your current directory. Errors
are populated in the quickfix window. If an argument is passed, [expand]
is used as file selector (useful for cases like `:GoTest ./...`).
You may optionally pass any valid go test flags/options. For a full list
please see `go help test`.
GoTest timesout automatically after 10 seconds. To customize the timeout
use |'g:go_test_timeout'|. This feature is disabled if any arguments are
passed to the `:GoTest` command.
If [!] is not given the first error is jumped to.
If using neovim `:GoTest` will run in a new terminal or run asynchronously
in the background according to |'g:go_term_enabled'|. You can set the mode
of the new terminal with |'g:go_term_mode'|.
*:GoTestFunc*
:GoTestFunc[!] [expand]
Runs :GoTest, but only on the single test function immediate to your
cursor using 'go test's '-run' flag.
Lookup is done starting at the cursor (including that line) moving up till
a matching `func Test` pattern is found or top of file is reached. Search
will not wrap around when at the top of the file.
If [!] is not given the first error is jumped to.
If using neovim `:GoTestFunc` will run in a new terminal or run
asynchronously in the background according to |'g:go_term_enabled'|. You
can set the mode of the new terminal with |'g:go_term_mode'|.
*:GoTestCompile*
:GoTestCompile[!] [expand]
Compile your _test.go files via in your current directory. Errors are
populated in the quickfix window. If an argument is passed, [expand] is
used as file selector (useful for cases like `:GoTest ./...`). Useful to
not run the tests and capture/fix errors before running the tests or to
create test binary.
If [!] is not given the first error is jumped to.
If using neovim `:GoTestCompile` will run in a new terminal or run
asynchronously in the background according to |'g:go_term_enabled'|. You
can set the mode of the new terminal with |'g:go_term_mode'|.

the quickfix window.
You may optionally pass any valid errcheck flags/options. See
`errcheck -h` for a full list.
*:GoFiles*
:GoFiles [source_files]
Show source files for the current package. The [source_files] specifies
which file types to list. See the "// Source files" section of
`go list -h` for possible values; multiple values are accepted.
Command-line completion also works for this command.
The default is to use `GoFiles` if no arguments are given.
*:GoDeps*
:GoDeps
Show dependencies for the current package.
*:GoInstallBinaries*
:GoInstallBinaries [binaries]
Download and install all necessary Go tool binaries such as `godef`,
`goimports`, `gocode`, etc. under |'g:go_bin_path'|. If [binaries] is
supplied, then only the specified binaries will be installed. The default
is to install everything.
Set |'g:go_get_update'| to disable updating dependencies.
*:GoUpdateBinaries*
:GoUpdateBinaries [binaries]
Download and update previously installed Go tool binaries such as `godef`,
`goimports`, `gocode`, etc. under |'g:go_bin_path'|. If [binaries] is

for the type that implements an interface under the cursor (or selected
package) is shown in a location list.
*:GoRename*
:GoRename[!] [to]
Rename the identifier under the cursor to the desired new name. If no
argument is given a prompt will ask for the desired identifier.
If [!] is not given the first error is jumped to.
*:GoGuruScope*
:GoGuruScope [pattern] [pattern2] ... [patternN]
Changes the custom |'g:go_guru_scope'| setting and overrides it with the
given package patterns. The custom scope is cleared (unset) if `""` is
given as the only path. If no arguments is given it prints the current
custom scope. Example patterns are:
>
golang.org/x/tools/cmd/guru # a single package
golang.org/x/tools/... # all packages beneath dir
... # the entire workspace.
<
Example usage, the following sets the scope to a `github.com/fatih/color`
and to all packages under `golang.org/x/tools/`:
>
:GoGuruScope github.com/fatih/color golang.org/x/tools/...
<
The following sets it to the entire workspace:
>
:GoGuruScope ...
<
Under the hood, the patterns are all joined to a comma-separated list and
passed to `guru`'s `-scope` flag.
Also see |go-guru-scope|.
*:GoCallees*
:GoCallees
Show "callees" relation for a selected package. A list of possible call
targets for the type under the cursor (or selected package) is shown in a
location list.

Show "callers" relation for a selected function. A list of possible
callers for the selected function under the cursor is shown in a location
list.
*:GoDescribe*
:GoDescribe
Shows various properties of the selected syntax: its syntactic kind, its
type (for an expression), its value (for a constant expression), its size,
alignment, method set and interfaces (for a type), its declaration (for an
identifier), etc. Almost any piece of syntax may be described, and the
guru will try to print all the useful information it can.
*:GoCallstack*
:GoCallstack
Shows "callstack" relation for the selected function. An arbitrary path
from the root of the callgraph to the selected function is shown in a
location list. This may be useful to understand how the function is
reached in a given program.
*:GoFreevars*
:GoFreevars
Enumerates the free variables of the selection. "Free variables" is a
technical term meaning the set of variables that are referenced but not
defined within the selection, or loosely speaking, its inputs.
This information is useful when considering whether to refactor the
selection into a function of its own, as the free variables would be the
necessary parameters of that function. It's also useful when you want to
understand what the inputs are to a complex block of code even if you
don’t plan to change it.
*:GoChannelPeers*
:GoChannelPeers
Shows the set of possible sends/receives on the channel operand of the
selected send or receive operation; the selection must be a `<-` token.
For example, visually select a channel operand in the form of:
>
done <- true
<
And call |:GoChannelPeers| on it. It will show where it was allocated, and
the sending and receiving endings.
*:GoReferrers*
:GoReferrers
The referrers query shows the set of identifiers that refer to the same
object as does the selected identifier, within any package in the analysis
scope.

:GoSameIdsToggle
Toggle between |:GoSameIds| and |:GoSameIdsClear|.
*:GoSameIdsAutoToggle*
:GoSameIdsAutoToggle
Enables or disables automatic highlighting of |:GoSameIds| while moving
the cursor. This basically toggles the option |'g:go_auto_sameids'|
on/off.
If enabled it starts highlighting whenever your cursor is staying at the
same position for a configurable period of time (see 'updatetime'). If
disabled it clears and stops automatic highlighting.
*:GoMetaLinter*
:GoMetaLinter [path]
Calls the underlying `gometalinter` tool and displays all warnings and
errors in the |quickfix| window. By default the following linters are
enabled: `vet`, `golint`, and `errcheck`. This can be changed with the
|'g:go_metalinter_enabled'| variable. To override the command completely
use the variable |'g:go_metalinter_command'|. To override the maximum
linters execution time use |'g:go_metalinter_deadline'| variable.
*:GoBuildTags*
:GoBuildTags [tags]
Changes the build tags for various commands. If you have any file that
uses a custom build tag, such as `// +build integration` , this command
can be used to pass it to all tools that accepts tags, such as guru,
gorename, etc.
The build tags is cleared (unset) if `""` is given. If no arguments are
given it prints the current build tags.
*:AsmFmt*
:AsmFmt
Filter the current Go asm buffer through asmfmt. It tries to preserve
cursor position and avoids replacing the buffer with stderr output.
*:GoAlternate*
:GoAlternate[!]
Alternates between the implementation and test code. For example if in
main.go, switch to main_test.go. Uses the |'g:go_alternate_mode'| setting
as the command to open the file.
If [!] is given then it switches to the new file even if it does not
exist.
If you would like to override the traditional commands for alternating,
add the following to your .vimrc:
>
augroup go
autocmd!
autocmd Filetype go
\ command! -bang A call go#alternate#Switch(<bang>0, 'edit')
\| command! -bang AV call go#alternate#Switch(<bang>0, 'vsplit')
\| command! -bang AS call go#alternate#Switch(<bang>0, 'split')
augroup END
<
*:GoPointsTo*
:GoPointsTo
Show all variables to which the pointer under the cursor may point to.

:GoDecls [file]
Show all function and type declarations for the current file. If
[file] is non empty it parses the given file.
Requires `ctrlp.vim` or `fzf`; it will autodetect the plugin if installed,
but you can use |'g:go_decls_mode'| to force using one or the other.
By default `type` and `func` declarations are shown. This can be changed
via |'g:go_decls_includes'|. Also see |unite-decls|, |denite-decls|.
*:GoDeclsDir*
:GoDeclsDir [dir]
Show all function and type declarations for the current directory. If
[dir] is given it parses the given directory.
*unite-decls*

declarations for all functions and types on the current file or directory
or for [path] if given.
Note: `denite.nvim` requires NeoVim or Vim 8 with |:python3| enabled.
>
" show declarations on the parent directory of the current file
:Unite decls
:Denite decls
" show declarations in the file.
:Unite decls:foo/bar.go
:Denite decls:foo/bar.go
" show declarations in the directory "foo".
:Unite decls:foo
:Denite decls:foo
<
*:GoImpl*
:GoImpl [receiver] [interface]
Generates method stubs for implementing an interface. If no arguments is
passed it takes the identifier under the cursor to be the receiver and
asks for the interface type to be generated. If used with arguments, the
receiver and the interface needs to be specified. Example usages:
>
:GoImpl f *Foo io.Writer
:GoImpl t Type io.ReadWriteCloser
<
*:GoAddTags*
:[range]GoAddTags [key],[option] [key1],[option] ...
Adds field tags for the fields of a struct. If called inside a struct it
automatically add field tags with the `json` key and the value
automatically generated based on the field name. An error message is given
if it's called outside a struct definition or if the file is not correctly
formatted.
If [range] is given, only the selected fields will be changed.
The default `json` can be changed by providing one or more [key]
arguments. An example of adding `xml` and `db` would be:
>
:GoAddTags xml db
<
If [option] is passed it'll either add a new tag with an option or will
modify existing tags. An example of adding `omitempty` to all `json`
fields would be:
>
:GoAddTags json,omitempty
<
You can define a constant value instead of the default field based value.
For example the following command will add ``valid:"1"`` to all fields.
>
:GoAddTags valid=1
<
*:GoRemoveTags*
:[range]GoRemoveTags [key],[option] [key1],[option1] ...
Rmove field tags for the fields of a struct. If called inside a struct it
automatically remove all field tags. An error message is given if it's
called outside a struct definition or if the file is not correctly
formatted
If [range] is given, only the selected fields will be changed.
If [key] is given, it will only remove those keys. Example:
>
:GoRemoveTags json
<
If [option] is passed with a [key], it will only remove the options.
Example, this will only remove `omitempty` options from fields containing
`json`:
>
:GoRemoveTags json,omitempty
<
*:GoAutoTypeInfoToggle*
:GoAutoTypeInfoToggle
Toggles |'g:go_auto_type_info'|.

window. The list to use can be set using |'g:go_list_type_commands'|.
*:GoTemplateAutoCreateToggle*
:GoTemplateAutoCreateToggle
Toggles |'g:go_template_autocreate'|.
*:GoKeyify*
:GoKeyify
Uses `keyify` to turn unkeyed struct literals into keyed ones.
For example:
>
Person{"John", "Smith"}
<
Becomes:
>
Person{
Name: "John",
Surname: "Smith",
}
<
*:GoFillStruct*
:GoFillStruct
Use `fillstruct` to fill a struct literal with default values. Existing
values (if any) are preserved. The cursor must be on the struct you wish
to fill.
For example:
>
addr := net.Address{Name: "Ford Prefect"}
<
Becomes:
>
addr := net.Address{
Name: "Ford Prefect",
Email: "",
}
<
