skeleton

skeleton creates skeleton codes for a modularized static analysis tool with x/tools/go/analysis package.

x/tools/go/analysis pacakge

x/tools/go/analysis package provides a type analysis.Analyzer which is unit of analyzers in modularized static analysis tool.

If you want to create new analyzer, you should provide a package variable which type is *analysis.Analyzer. skeleton creates skeleton codes of the package and directories including test codes and main.go.

Insall

$ go get -u github.com/gostaticanalysis/skeleton

How to use

Create skeleton codes in GOPATH

$ skeleton pkgname
pkgname
├── cmd
│   └── pkgname
│       └── main.go
├── go.mod
├── pkgname.go
├── pkgname_test.go
├── plugin
│   └── main.go
└── testdata
    └── src
        └── a
            ├── a.go
            └── go.mod

Create skeleton codes with import path

$ skeleton -path="github.com/gostaticanalysis/pkgname"
pkgname
├── cmd
│   └── pkgname
│       └── main.go
├── go.mod
├── pkgname.go
├── pkgname_test.go
├── plugin
│   └── main.go
└── testdata
    └── src
        └── a
            ├── a.go
            └── go.mod

Overwrite existing directory

If you want to overwrite without confirmation, you can run with -overwrite option.

$ skeleton -overwrite pkgname

If you run skeleton without -overwrite option, skeleton show optoins.

$ skeleton pkgname
pkgname already exist, remove?
[1] No(Exit)
[2] Remove and create new directory
[3] Overwrite existing files with confirmation
[4] Create new files only

Create skeleton codes without cmd directory

$ skeleton -cmd=false pkgname
pkgname
├── go.mod
├── pkgname.go
├── pkgname_test.go
├── plugin
│   └── main.go
└── testdata
    └── src
        └── a
            ├── a.go
            └── go.mod

Create skeleton codes without go.mod

$ skeleton -mod=false pkgname
pkgname
├── cmd
│   └── pkgname
│       └── main.go
├── pkgname.go
├── pkgname_test.go
├── plugin
│   └── main.go
└── testdata
    └── src
        └── a
            ├── a.go
            └── go.mod

Change the checker from unitchecker to singlechecker or multichecker

You can change the checker from unitchecker to singlechecker or multichecker.

$ skeleton -checker=single pkgname
$ cat cmd/pkgname/main.go
package main

import (
		"pkgname"
		"golang.org/x/tools/go/analysis/singlechecker"
)

func main() { singlechecker.Main(pkgname.Analyzer) }

Create skeleton codes without plugin directory

$ skeleton -plugin=false pkgname
pkgname
├── cmd
│   └── pkgname
│       └── main.go
├── go.mod
├── pkgname.go
├── pkgname_test.go
└── testdata
    └── src
        └── a
            ├── a.go
            └── go.mod

Create skeleton codes of codegenerator

$ skeleton -type=codegen pkgname
pkgname
├── cmd
│   └── pkgname
│       └── main.go
├── go.mod
├── pkgname.go
├── pkgname_test.go
└── testdata
    └── src
        └── a
            ├── a.go
            └── pkgname.golden

Change type of skeleton code

skeleton accepts -type option which indicates type of skeleton code.

• -type=inspect(default): generate skeleton code with inspect.Analyzer
• -type=ssa: generate skeleton code with buildssa.Analyzer
• -type=codegen: generate skeleton code of a code generator

Build as a plugin for golangci-lint

skeleton generates plugin directory which has main.go. The main.go can be built as a plugin for golangci-lint.

$ skeleton pkgname
$ go build -buildmode=plugin -o path_to_plugin_dir importpath

If you would like to specify flags for your plugin, you can put them via ldflags as below.

$ skeleton pkgname
$ go build -buildmode=plugin -ldflags "-X 'main.flags=-funcs log.Fatal'" -o path_to_plugin_dir github.com/gostaticanalysis/called/plugin/called
