**ATTN**: This project uses [semantic versioning](http://semver.org/).
## [Unreleased]
## [1.19.1] - 2016-11-21
### Fixed
- Fixes regression introduced in 1.19.0 where using an `ActionFunc` as
the `Action` for a command would cause it to error rather than calling the
function. Should not have a affected declarative cases using `func(c
*cli.Context) err)`.
- Shell completion now handles the case where the user specifies
`--generate-bash-completion` immediately after a flag that takes an argument.
Previously it call the application with `--generate-bash-completion` as the
flag value.
## [1.19.0] - 2016-11-19
### Added
- `FlagsByName` was added to make it easy to sort flags (e.g. `sort.Sort(cli.FlagsByName(app.Flags))`)
- A `Description` field was added to `App` for a more detailed description of
the application (similar to the existing `Description` field on `Command`)
- Flag type code generation via `go generate`
- Write to stderr and exit 1 if action returns non-nil error
- Added support for TOML to the `altsrc` loader
- `SkipArgReorder` was added to allow users to skip the argument reordering.
This is useful if you want to consider all "flags" after an argument as
arguments rather than flags (the default behavior of the stdlib `flag`
library). This is backported functionality from the [removal of the flag
reordering](https://github.com/urfave/cli/pull/398) in the unreleased version
2
- For formatted errors (those implementing `ErrorFormatter`), the errors will
be formatted during output. Compatible with `pkg/errors`.
### Changed
- Raise minimum tested/supported Go version to 1.2+
### Fixed
- Consider empty environment variables as set (previously environment variables
with the equivalent of `""` would be skipped rather than their value used).
- Return an error if the value in a given environment variable cannot be parsed
as the flag type. Previously these errors were silently swallowed.
- Print full error when an invalid flag is specified (which includes the invalid flag)
- `App.Writer` defaults to `stdout` when `nil`
- If no action is specified on a command or app, the help is now printed instead of `panic`ing
- `App.Metadata` is initialized automatically now (previously was `nil` unless initialized)
- Correctly show help message if `-h` is provided to a subcommand
- `context.(Global)IsSet` now respects environment variables. Previously it
would return `false` if a flag was specified in the environment rather than
as an argument
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
- `altsrc`s import paths were updated to use `gopkg.in/urfave/cli.v1`. This
fixes issues that occurred when `gopkg.in/urfave/cli.v1` was imported as well
as `altsrc` where Go would complain that the types didn't match
## [1.18.1] - 2016-08-28
### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user (backported)
## [1.18.0] - 2016-06-27
### Added
- `./runtests` test runner with coverage tracking by default
@ -28,6 +77,10 @@
- No longer swallows `panic`s that occur within the `Action`s themselves when

### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user

#### Ordering
Flags for the application and commands are shown in the order they are defined.
However, it's possible to sort them from outside this library by using `FlagsByName`
or `CommandsByName` with `sort`.
For example this:
<!-- {
"args": ["&#45;&#45;help"],
"output": "add a task to the list\n.*complete a task on the list\n.*\n\n.*\n.*Load configuration from FILE\n.*Language for the greeting.*"
} -->
``` go
package main
import (
"os"
"sort"
"github.com/urfave/cli"
)
func main() {
app := cli.NewApp()
app.Flags = []cli.Flag {
cli.StringFlag{
Name: "lang, l",
Value: "english",
Usage: "Language for the greeting",
},
cli.StringFlag{
Name: "config, c",
Usage: "Load configuration from `FILE`",
},
}
app.Commands = []cli.Command{
{
Name: "complete",
Aliases: []string{"c"},
Usage: "complete a task on the list",
Action: func(c *cli.Context) error {
return nil
},
},
{
Name: "add",
Aliases: []string{"a"},
Usage: "add a task to the list",
Action: func(c *cli.Context) error {
return nil
},
},
}
sort.Sort(cli.FlagsByName(app.Flags))
sort.Sort(cli.CommandsByName(app.Commands))
app.Run(os.Args)
}
```
Will result in help output like:
```
--config FILE, -c FILE Load configuration from FILE
--lang value, -l value Language for the greeting (default: "english")
```
