-
-cli is a simple, fast, and fun package for building command line apps in Go. The
-goal is to enable developers to write fast and distributable command line
-applications in an expressive way.
-
-## Usage Documentation
-
-Usage documentation for `v1` is available [at the docs
-site](https://cli.urfave.org/v1/getting-started/) or in-tree at
-[./docs/v1/manual.md](./docs/v1/manual.md)
-
-## Installation
-
-Make sure you have a working Go environment. Go version 1.18+ is supported.
-
-### Supported platforms
-
-cli is tested against multiple versions of Go on Linux, and against the latest released
-version of Go on OS X and Windows.  For full details, see
-[./.github/workflows/cli.yml](./.github/workflows/cli.yml).
-
-### Build tags
-
-You can use the following build tags:
-
-#### `urfave_cli_no_docs`
-
-When set, this removes `ToMarkdown` and `ToMan` methods, so your application
-won't be able to call those. This reduces the resulting binary size by about
-300-400 KB (measured using Go 1.18.1 on Linux/amd64), due to less dependencies.
-
-### Using `v1` releases
-
-```
-$ go get github.com/urfave/cli
-```
-
-```go
-...
-import (
-  "github.com/urfave/cli"
-)
-...
-```

+
+var HelpPrinter helpPrinter = printHelp
+    HelpPrinter is a function that writes the help output. If not set
+    explicitly, this calls HelpPrinterCustom using only the default template
+    functions.
+
+    If custom logic for printing help is required, this function can be
+    overridden. If the ExtraInfo field is defined on an App, this function
+    should not be modified, as HelpPrinterCustom will be used directly in order
+    to capture the extra information.
+
+var HelpPrinterCustom helpPrinterCustom = printHelpCustom
+    HelpPrinterCustom is a function that writes the help output. It is used as
+    the default implementation of HelpPrinter, and may be called directly if the
+    ExtraInfo field is set on an App.
+
+    In the default implementation, if the customFuncs argument contains a
+    "wrapAt" key, which is a function which takes no arguments and returns an
+    int, this int value will be used to produce a "wrap" function used by the
+    default template to wrap long lines.

+
+FUNCTIONS
+
+func DefaultAppComplete(cCtx *Context)
+    DefaultAppComplete prints the list of subcommands as the default app
+    completion method
+
+func DefaultCompleteWithFlags(cmd *Command) func(cCtx *Context)

+
+func HandleExitCoder(err error)
+    HandleExitCoder handles errors implementing ExitCoder by printing their
+    message and calling OsExiter with the given exit code.

+    If the given error instead implements MultiError, each error will be checked
+    for the ExitCoder interface, and OsExiter will be called with the last exit

+}
+    HelpFlag prints the help for all commands and subcommands. Set to nil to
+    disable the flag. The subcommand will still be added unless HideHelp or
+    HideHelpCommand is set to true.

+
+There are implementations for calculating the popular Levenshtein distance (aka Edit Distance or Wagner-Fischer), as well as the Jaro distance, the Jaro-Winkler distance, and more.
