UsageLine: "go mod download [-dir] [-json] [modules]",
Short: "download modules to local cache",
Long: `
Download downloads the named modules, which can be module patterns selecting
dependencies of the main module or module queries of the form path@version.
With no arguments, download applies to all dependencies of the main module.
The go command will automatically download modules as needed during ordinary
execution. The "go mod download" command is useful mainly for pre-filling
the local cache or to compute the answers for a Go module proxy.
By default, download reports errors to standard error but is otherwise silent.
The -json flag causes download to print a sequence of JSON objects
to standard output, describing each downloaded module (or failure),
corresponding to this Go struct:
type Module struct {
Path string // module path
Version string // module version
Error string // error loading module
Info string // absolute path to cached .info file
GoMod string // absolute path to cached .mod file
Zip string // absolute path to cached .zip file
Dir string // absolute path to cached source root directory
Sum string // checksum for path, version (as in go.sum)
GoModSum string // checksum for go.mod (as in go.sum)
}
See 'go help modules' for more about module queries.

package modcmd

)
var cmdFix = &base.Command{
UsageLine: "go mod fix",
Short: "make go.mod semantically consistent",
Long: `
Fix updates go.mod to use canonical version identifiers and
to be semantically consistent. For example, consider this go.mod file:
module M
require (
A v1
B v1.0.0
C v1.0.0
D v1.2.3
E dev
)
exclude D v1.2.3
First, fix rewrites non-canonical version identifiers to semver form, so
A's v1 becomes v1.0.0 and E's dev becomes the pseudo-version for the latest
commit on the dev branch, perhaps v0.0.0-20180523231146-b3f5c0f6e5f1.
Next, fix updates requirements to respect exclusions, so the requirement
on the excluded D v1.2.3 is updated to use the next available version of D,
perhaps D v1.2.4 or D v1.3.0.
Finally, fix removes redundant or misleading requirements.
For example, if A v1.0.0 itself requires B v1.2.0 and C v1.0.0, then go.mod's
requirement of B v1.0.0 is misleading (superseded by A's need for v1.2.0),
and its requirement of C v1.0.0 is redundant (implied by A's need for the
same version), so both will be removed. If module M contains packages
that directly import packages from B or C, then the requirements will be
kept but updated to the actual versions being used.
Although fix runs the fix-up operation in isolation, the fix-up also
runs automatically any time a go command uses the module graph,
to update go.mod to reflect reality. Because the module graph defines
the meaning of import statements, any commands that load packages
also use and therefore fix the module graph. For example,
go build, go get, go install, go list, go test, go mod graph, go mod tidy,
and other commands all effectively imply go mod fix.

UsageLine: "go mod why [-m] [-vendor] packages...",
Short: "explain why packages or modules are needed",
Long: `
Why shows a shortest path in the import graph from the main module to
each of the listed packages. If the -m flag is given, why treats the
arguments as a list of modules and finds a path to any package in each
of the modules.
By default, why queries the graph of packages matched by "go list all",
which includes tests for reachable packages. The -vendor flag causes why
to exclude tests of dependencies.
The output is a sequence of stanzas, one for each package or module
name on the command line, separated by blank lines. Each stanza begins
with a comment line "# package" or "# module" giving the target
package or module. Subsequent lines give a path through the import
graph, one package per line. If the package or module is not
referenced from the main module, the stanza will display a single
parenthesized note indicating that fact.
For example:
$ go mod why golang.org/x/text/language golang.org/x/text/encoding
# golang.org/x/text/language
rsc.io/quote
rsc.io/sampler
golang.org/x/text/language

var HelpGoMod = &base.Command{
UsageLine: "go.mod",
Short: "the go.mod file",
Long: `
A module version is defined by a tree of source files, with a go.mod
file in its root. When the go command is run, it looks in the current
directory and then successive parent directories to find the go.mod
marking the root of the main (current) module.
The go.mod file itself is line-oriented, with // comments but
no /* */ comments. Each line holds a single directive, made up of a
verb followed by arguments. For example:
module my/thing
require other/thing v1.0.2
require new/thing v2.3.4
exclude old/thing v1.2.3
replace bad/thing v1.4.5 => good/thing v1.4.5
The verbs are module, to define the module path; require, to require
a particular module at a given version or later; exclude, to exclude
a particular module version from use; and replace, to replace a module
version with a different module version. Exclude and replace apply only
in the main module's go.mod and are ignored in dependencies.
See https://research.swtch.com/vgo-mvs for details.
The leading verb can be factored out of adjacent lines to create a block,
like in Go imports:
require (
new/thing v2.3.4
old/thing v1.2.3
)
The go.mod file is designed both to be edited directly and to be
easily updated by tools. The 'go mod edit' command can be used to
parse and edit the go.mod file from programs and tools.
See 'go help mod edit'.
The go command automatically updates go.mod each time it uses the
module graph, to make sure go.mod always accurately reflects reality
and is properly formatted. For example, consider this go.mod file:
module M
require (
A v1
B v1.0.0
C v1.0.0
D v1.2.3
E dev
)
exclude D v1.2.3
The update rewrites non-canonical version identifiers to semver form,
so A's v1 becomes v1.0.0 and E's dev becomes the pseudo-version for the
latest commit on the dev branch, perhaps v0.0.0-20180523231146-b3f5c0f6e5f1.
The update modifies requirements to respect exclusions, so the
requirement on the excluded D v1.2.3 is updated to use the next
available version of D, perhaps D v1.2.4 or D v1.3.0.
The update removes redundant or misleading requirements.
For example, if A v1.0.0 itself requires B v1.2.0 and C v1.0.0,
then go.mod's requirement of B v1.0.0 is misleading (superseded by
A's need for v1.2.0), and its requirement of C v1.0.0 is redundant
(implied by A's need for the same version), so both will be removed.
If module M contains packages that directly import packages from B or
C, then the requirements will be kept but updated to the actual
versions being used.
Finally, the update reformats the go.mod in a canonical formatting, so
that future mechanical changes will result in minimal diffs.
Because the module graph defines the meaning of import statements, any
commands that load packages also use and therefore update go.mod,
including go build, go get, go install, go list, go test, go mod graph,
go mod tidy, and go mod why.
