**ATTN**: This project uses [semantic versioning](http://semver.org/).
## [Unreleased]
## 1.20.0 - 2017-08-10
### Fixed
* `HandleExitCoder` is now correctly iterates over all errors in
a `MultiError`. The exit code is the exit code of the last error or `1` if
there are no `ExitCoder`s in the `MultiError`.
* Fixed YAML file loading on Windows (previously would fail validate the file path)
* Subcommand `Usage`, `Description`, `ArgsUsage`, `OnUsageError` correctly
propogated
* `ErrWriter` is now passed downwards through command structure to avoid the
need to redefine it
* Pass `Command` context into `OnUsageError` rather than parent context so that
all fields are avaiable
* Errors occuring in `Before` funcs are no longer double printed
* Use `UsageText` in the help templates for commands and subcommands if
defined; otherwise build the usage as before (was previously ignoring this
field)
* `IsSet` and `GlobalIsSet` now correctly return whether a flag is set if
a program calls `Set` or `GlobalSet` directly after flag parsing (would
previously only return `true` if the flag was set during parsing)
### Changed
* No longer exit the program on command/subcommand error if the error raised is
not an `OsExiter`. This exiting behavior was introduced in 1.19.0, but was
determined to be a regression in functionality. See [the
PR](https://github.com/urfave/cli/pull/595) for discussion.
### Added
* `CommandsByName` type was added to make it easy to sort `Command`s by name,
alphabetically
* `altsrc` now handles loading of string and int arrays from TOML
* Support for definition of custom help templates for `App` via
`CustomAppHelpTemplate`
* Support for arbitrary key/value fields on `App` to be used with
`CustomAppHelpTemplate` via `ExtraInfo`
* `HelpFlag`, `VersionFlag`, and `BashCompletionFlag` changed to explictly be
`cli.Flag`s allowing for the use of custom flags satisfying the `cli.Flag`
interface to be used.
## [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

- Removed deprecation warnings to STDERR to avoid them leaking to the end-user (backported)
## [1.18.0] - 2016-06-27
