# garif
|
||||
|
||||
A GO package to create and manipulate SARIF logs.
|
||||
|
||||
SARIF, from _Static Analysis Results Interchange Format_, is a standard JSON-based format for the output of static analysis tools defined and promoted by [OASIS](https://www.oasis-open.org/).
|
||||
|
||||
Current supported version of the standard is [SARIF-v2.1.0](https://docs.oasis-open.org/sarif/sarif/v2.1.0/csprd01/sarif-v2.1.0-csprd01.html
|
||||
).
|
||||
|
||||
## Usage
|
||||
|
||||
The package provides access to every element of the SARIF model, therefore you are free to manipulate it at every detail.
|
||||
|
||||
The package also provides constructors functions (`New...`) and decorators methods (`With...`) that simplify the creation of SARIF files for common use cases.
|
||||
|
||||
Using these constructors and decorators we can easily create the example SARIF file of the [Microsoft SARIF pages](https://github.com/microsoft/sarif-tutorials/blob/master/docs/1-Introduction.md)
|
||||
|
||||
|
||||
```go
|
||||
import to `github.com/chavacava/garif`
|
||||
|
||||
// ...
|
||||
|
||||
rule := garif.NewRule("no-unused-vars").
|
||||
WithHelpUri("https://eslint.org/docs/rules/no-unused-vars").
|
||||
WithShortDescription("disallow unused variables").
|
||||
WithProperties("category", "Variables")
|
||||
|
||||
driver := garif.NewDriver("ESLint").
|
||||
WithInformationUri("https://eslint.org").
|
||||
WithRules(rule)
|
||||
|
||||
run := garif.NewRun(NewTool(driver)).
|
||||
WithArtifactsURIs("file:///C:/dev/sarif/sarif-tutorials/samples/Introduction/simple-example.js")
|
||||
|
||||
run.WithResult(rule.Id, "'x' is assigned a value but never used.", "file:///C:/dev/sarif/sarif-tutorials/samples/Introduction/simple-example.js", 1, 5)
|
||||
|
||||
logFile := garif.NewLogFile([]*Run{run}, Version210)
|
||||
|
||||
logFile.Write(os.Stdout)
|
||||
```
|
||||
|
||||
## Why this package?
|
||||
This package was initiated during my works on adding to [`revive`](https://github.com/mgechev/revive) a SARIF output formatter.
|
||||
I've tried to use [go-sarif](https://github.com/owenrumney/go-sarif) by [Owen Rumney](https://github.com/owenrumney) but it is too focused in the use case of the static analyzer [tfsec](https://tfsec.dev) so I've decided to create a package flexible enough to generate SARIF files in broader cases.
|
||||
|
||||
## More information about SARIF
|
||||
For more information about SARIF, you can visit the [Oasis Open](https://www.oasis-open.org/committees/tc_home.php?wg_abbrev=sarif) site.
|
||||
|
||||
|
||||
## Contributing
|
||||
Of course, contributions are welcome!

# color [](https://github.com/fatih/color/actions) [](https://pkg.go.dev/github.com/fatih/color)
|
||||
|
||||
Color lets you use colorized outputs in terms of [ANSI Escape
|
||||
Codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors) in Go (Golang). It
|
||||
has support for Windows too! The API can be used in several ways, pick one that
|
||||
suits you.
|
||||
|
||||
|
||||
|
||||
|
||||
## Install
|
||||
|
||||
```bash
|
||||
go get github.com/fatih/color
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
### Standard colors
|
||||
|
||||
```go
|
||||
// Print with default helper functions
|
||||
color.Cyan("Prints text in cyan.")
|
||||
|
||||
// A newline will be appended automatically
|
||||
color.Blue("Prints %s in blue.", "text")
|
||||
|
||||
// These are using the default foreground colors
|
||||
color.Red("We have red")
|
||||
color.Magenta("And many others ..")
|
||||
|
||||
```
|
||||
|
||||
### Mix and reuse colors
|
||||
|
||||
```go
|
||||
// Create a new color object
|
||||
c := color.New(color.FgCyan).Add(color.Underline)
|
||||
c.Println("Prints cyan text with an underline.")
|
||||
|
||||
// Or just add them to New()
|
||||
d := color.New(color.FgCyan, color.Bold)
|
||||
d.Printf("This prints bold cyan %s\n", "too!.")
|
||||
|
||||
// Mix up foreground and background colors, create new mixes!
|
||||
red := color.New(color.FgRed)
|
||||
|
||||
boldRed := red.Add(color.Bold)
|
||||
boldRed.Println("This will print text in bold red.")
|
||||
|
||||
whiteBackground := red.Add(color.BgWhite)
|
||||
whiteBackground.Println("Red text with white background.")
|
||||
```
|
||||
|
||||
### Use your own output (io.Writer)
|
||||
|
||||
```go
|
||||
// Use your own io.Writer output
|
||||
color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
|
||||
|
||||
blue := color.New(color.FgBlue)
|
||||
blue.Fprint(writer, "This will print text in blue.")
|
||||
```
|
||||
|
||||
### Custom print functions (PrintFunc)
|
||||
|
||||
```go
|
||||
// Create a custom print function for convenience
|
||||
red := color.New(color.FgRed).PrintfFunc()
|
||||
red("Warning")
|
||||
red("Error: %s", err)
|
||||
|
||||
// Mix up multiple attributes
|
||||
notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
|
||||
notice("Don't forget this...")
|
||||
```
|
||||
|
||||
### Custom fprint functions (FprintFunc)
|
||||
|
||||
```go
|
||||
blue := color.New(FgBlue).FprintfFunc()
|
||||
blue(myWriter, "important notice: %s", stars)
|
||||
|
||||
// Mix up with multiple attributes
|
||||
success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
|
||||
success(myWriter, "Don't forget this...")
|
||||
```
|
||||
|
||||
### Insert into noncolor strings (SprintFunc)
|
||||
|
||||
```go
|
||||
// Create SprintXxx functions to mix strings with other non-colorized strings:
|
||||
yellow := color.New(color.FgYellow).SprintFunc()
|
||||
red := color.New(color.FgRed).SprintFunc()
|
||||
fmt.Printf("This is a %s and this is %s.\n", yellow("warning"), red("error"))
|
||||
|
||||
info := color.New(color.FgWhite, color.BgGreen).SprintFunc()
|
||||
fmt.Printf("This %s rocks!\n", info("package"))
|
||||
|
||||
// Use helper functions
|
||||
fmt.Println("This", color.RedString("warning"), "should be not neglected.")
|
||||
fmt.Printf("%v %v\n", color.GreenString("Info:"), "an important message.")
|
||||
|
||||
// Windows supported too! Just don't forget to change the output to color.Output
|
||||
fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
|
||||
```
|
||||
|
||||
### Plug into existing code
|
||||
|
||||
```go
|
||||
// Use handy standard colors
|
||||
color.Set(color.FgYellow)
|
||||
|
||||
fmt.Println("Existing text will now be in yellow")
|
||||
fmt.Printf("This one %s\n", "too")
|
||||
|
||||
color.Unset() // Don't forget to unset
|
||||
|
||||
// You can mix up parameters
|
||||
color.Set(color.FgMagenta, color.Bold)
|
||||
defer color.Unset() // Use it in your function
|
||||
|
||||
fmt.Println("All text will now be bold magenta.")
|
||||
```
|
||||
|
||||
### Disable/Enable color
|
||||
|
||||
There might be a case where you want to explicitly disable/enable color output. the
|
||||
`go-isatty` package will automatically disable color output for non-tty output streams
|
||||
(for example if the output were piped directly to `less`)
|
||||
|
||||
`Color` has support to disable/enable colors both globally and for single color
|
||||
definitions. For example suppose you have a CLI app and a `--no-color` bool flag. You
|
||||
can easily disable the color output with:
|
||||
|
||||
```go
|
||||
|
||||
var flagNoColor = flag.Bool("no-color", false, "Disable color output")
|
||||
|
||||
if *flagNoColor {
|
||||
color.NoColor = true // disables colorized output
|
||||
}
|
||||
```
|
||||
|
||||
It also has support for single color definitions (local). You can
|
||||
disable/enable color output on the fly:
|
||||
|
||||
```go
|
||||
c := color.New(color.FgCyan)
|
||||
c.Println("Prints cyan text")
|
||||
|
||||
c.DisableColor()
|
||||
c.Println("This is printed without any color")
|
||||
|
||||
c.EnableColor()
|
||||
c.Println("This prints again cyan...")
|
||||
```
|
||||

||||

/*
|

Package color is an ANSI color package to output colorized or SGR defined
|
||||
output to the standard output. The API can be used in several way, pick one
|
||||
that suits you.
|
||||
|
||||
Use simple and default helper functions with predefined foreground colors:
|
||||
|
||||
color.Cyan("Prints text in cyan.")
|
||||
|
||||
// a newline will be appended automatically
|
||||
color.Blue("Prints %s in blue.", "text")
|
||||
|
||||
// More default foreground colors..
|
||||
color.Red("We have red")
|
||||
color.Yellow("Yellow color too!")
|
||||
color.Magenta("And many others ..")
|
||||
|
||||
// Hi-intensity colors
|
||||
color.HiGreen("Bright green color.")
|
||||
color.HiBlack("Bright black means gray..")
|
||||
color.HiWhite("Shiny white color!")
|
||||
|
||||
However there are times where custom color mixes are required. Below are some
|
||||
examples to create custom color objects and use the print functions of each
|
||||
separate color object.
|
||||
|
||||
// Create a new color object
|
||||
c := color.New(color.FgCyan).Add(color.Underline)
|
||||
c.Println("Prints cyan text with an underline.")
|
||||
|
||||
// Or just add them to New()
|
||||
d := color.New(color.FgCyan, color.Bold)
|
||||
d.Printf("This prints bold cyan %s\n", "too!.")
|
||||
|
||||
|
||||
// Mix up foreground and background colors, create new mixes!
|
||||
red := color.New(color.FgRed)
|
||||
|
||||
boldRed := red.Add(color.Bold)
|
||||
boldRed.Println("This will print text in bold red.")
|
||||
|
||||
whiteBackground := red.Add(color.BgWhite)
|
||||
whiteBackground.Println("Red text with White background.")
|
||||
|
||||
// Use your own io.Writer output
|
||||
color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
|
||||
|
||||
blue := color.New(color.FgBlue)
|
||||
blue.Fprint(myWriter, "This will print text in blue.")
|
||||
|
||||
You can create PrintXxx functions to simplify even more:
|
||||
|
||||
// Create a custom print function for convenient
|
||||
red := color.New(color.FgRed).PrintfFunc()
|
||||
red("warning")
|
||||
red("error: %s", err)
|
||||
|
||||
// Mix up multiple attributes
|
||||
notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
|
||||
notice("don't forget this...")
|
||||
|
||||
You can also FprintXxx functions to pass your own io.Writer:
|
||||
|
||||
blue := color.New(FgBlue).FprintfFunc()
|
||||
blue(myWriter, "important notice: %s", stars)
|
||||
|
||||
// Mix up with multiple attributes
|
||||
success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
|
||||
success(myWriter, don't forget this...")
|
||||
|
||||
|
||||
Or create SprintXxx functions to mix strings with other non-colorized strings:
|
||||
|
||||
yellow := New(FgYellow).SprintFunc()
|
||||
red := New(FgRed).SprintFunc()
|
||||
|
||||
fmt.Printf("this is a %s and this is %s.\n", yellow("warning"), red("error"))
|
||||
|
||||
info := New(FgWhite, BgGreen).SprintFunc()
|
||||
fmt.Printf("this %s rocks!\n", info("package"))
|
||||
|
||||
Windows support is enabled by default. All Print functions work as intended.
|
||||
However only for color.SprintXXX functions, user should use fmt.FprintXXX and
|
||||
set the output to color.Output:
|
||||

Using with existing code is possible. Just use the Set() method to set the
|
||||
standard output to the given parameters. That way a rewrite of an existing
|
||||
code is not required.
|
||||
|
||||
// Use handy standard colors.
|
||||
color.Set(color.FgYellow)
|
||||
|
||||
fmt.Println("Existing text will be now in Yellow")
|
||||
fmt.Printf("This one %s\n", "too")
|
||||
|
||||
color.Unset() // don't forget to unset
|
||||
|
||||
// You can mix up parameters
|
||||
color.Set(color.FgMagenta, color.Bold)
|
||||
defer color.Unset() // use it in your function
|
||||
|
||||
fmt.Println("All text will be now bold magenta.")
|
||||
|
||||
There might be a case where you want to disable color output (for example to
|
||||
pipe the standard output of your app to somewhere else). `Color` has support to
|
||||
disable colors both globally and for single color definition. For example
|
||||
suppose you have a CLI app and a `--no-color` bool flag. You can easily disable
|
||||
the color output with:
|
||||
|
||||
var flagNoColor = flag.Bool("no-color", false, "Disable color output")
|
||||
|
||||
if *flagNoColor {
|
||||
color.NoColor = true // disables colorized output
|
||||
}
|
||||
|
||||
It also has support for single color definitions (local). You can
|
||||
disable/enable color output on the fly:
|
||||
|
||||
c := color.New(color.FgCyan)
|
||||
c.Println("Prints cyan text")
|
||||
|
||||
c.DisableColor()
|
||||
c.Println("This is printed without any color")
|
||||
|
||||
c.EnableColor()
|
||||
c.Println("This prints again cyan...")

# structtag [](http://godoc.org/github.com/fatih/structtag)
|
||||
|
||||
structtag provides an easy way of parsing and manipulating struct tag fields.
|
||||
Please vendor the library as it might change in future versions.
|
||||
|
||||
# Install
|
||||
|
||||
```bash
|
||||
go get github.com/fatih/structtag
|
||||

|

Colorable writer for windows.
|
||||
|
||||
For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
|
||||
This package is possible to handle escape sequence for ansi color on windows.
|
||||
|
||||
## Too Bad!
|
||||
|
||||
|
||||
|
||||
|
||||
## So Good!
|
||||
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
```go
|
||||
logrus.SetFormatter(&logrus.TextFormatter{ForceColors: true})
|
||||
logrus.SetOutput(colorable.NewColorableStdout())
|
||||
|
||||
logrus.Info("succeeded")
|
||||
logrus.Warn("not correct")
|
||||
logrus.Error("something error")
|
||||
logrus.Fatal("panic")
|
||||
```
|
||||
|
||||
You can compile above code on non-windows OSs.
|
||||
|
||||
## Installation
|
||||
|
||||
```
|
||||
$ go get github.com/mattn/go-colorable
|

# Dots
|
||||
|
||||
Implements the wildcard file matching in Go used by golint, go test etc.
|
||||
|
||||
## Usage
|
||||
|
||||
```go
|
||||
import "github.com/mgechev/dots"
|
||||
|
||||
func main() {
|
||||
result, err := dots.Resolve([]string{"./fixtures/..."}, []string{"./fixtures/foo"})
|
||||
for _, f := range result {
|
||||
fmt.Println(f);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
If we suppose that we have the following directory structure:
|
||||
|
||||
```text
|
||||
├── README.md
|
||||
├── fixtures
|
||||
│ ├── bar
|
||||
│ │ ├── bar1.go
|
||||
│ │ └── bar2.go
|
||||
│ ├── baz
|
||||
│ │ ├── baz1.go
|
||||
│ │ ├── baz2.go
|
||||
│ │ └── baz3.go
|
||||
│ └── foo
|
||||
│ ├── foo1.go
|
||||
│ ├── foo2.go
|
||||
│ └── foo3.go
|
||||
└── main.go
|
||||
```
|
||||
|
||||
The result will be:
|
||||
|
||||
```text
|
||||
fixtures/bar/bar1.go
|
||||
fixtures/bar/bar2.go
|
||||
fixtures/baz/baz1.go
|
||||
fixtures/baz/baz2.go
|
||||
fixtures/baz/baz3.go
|
||||
```
|
||||
|
||||
`dots` supports wildcard in both - the first and the last argument of `Resolve`, which means that you can ignore files based on a wildcard:
|
||||
|
||||
```go
|
||||
dots.Resolve([]string{"github.com/mgechev/dots"}, []string{"./..."}) // empty list
|
||||
dots.Resolve([]string{"./fixtures/bar/..."}, []string{"./fixture/foo/...", "./fixtures/baz/..."}) // bar1.go, bar2.go
|
||||
```
|
||||
|
||||
## Preserve package structure
|
||||
|
||||
`dots` allow you to receive a slice of slices where each nested slice represents an individual package:
|
||||
|
||||
```go
|
||||
dots.ResolvePackages([]string{"github.com/mgechev/dots/..."}, []string{})
|
||||
```
|
||||
|
||||
So we will get the result:
|
||||
|
||||
```text
|
||||
[
|
||||
[
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/bar/bar1.go",
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/bar/bar2.go"
|
||||
],
|
||||
[
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/baz/baz1.go",
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/baz/baz2.go",
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/baz/baz3.go"
|
||||
],
|
||||
[
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/foo/foo1.go",
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/foo/foo2.go",
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/foo/foo3.go"
|
||||
],
|
||||
[
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/baz/baz1.go",
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/baz/baz2.go"
|
||||
],
|
||||
[
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/foo/foo1.go",
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/foo/foo2.go"
|
||||
],
|
||||
[
|
||||
"$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/foo/bar/bar1.go"
|
||||
]
|
||||
]
|
||||
```
|
||||
|
||||
This method is especially useful, when you want to perform type checking over given package from the result.
