# Change Log
**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
- testing on OS X
- testing on Windows
- `UintFlag`, `Uint64Flag`, and `Int64Flag` types and supporting code
### Changed
- Use spaces for alignment in help/usage output instead of tabs, making the
output alignment consistent regardless of tab width
### Fixed
- Printing of command aliases in help text
- Printing of visible flags for both struct and struct pointer flags
- Display the `help` subcommand when using `CommandCategories`
- No longer swallows `panic`s that occur within the `Action`s themselves when
detecting the signature of the `Action` field
## [1.17.1] - 2016-08-28
### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
## [1.17.0] - 2016-05-09
### Added
- Pluggable flag-level help text rendering via `cli.DefaultFlagStringFunc`
- `context.GlobalBoolT` was added as an analogue to `context.GlobalBool`
- Support for hiding commands by setting `Hidden: true` -- this will hide the
commands in help output
### Changed
- `Float64Flag`, `IntFlag`, and `DurationFlag` default values are no longer
quoted in help text output.
- All flag types now include `(default: {value})` strings following usage when a
default value can be (reasonably) detected.
- `IntSliceFlag` and `StringSliceFlag` usage strings are now more consistent
with non-slice flag types
- Apps now exit with a code of 3 if an unknown subcommand is specified
(previously they printed "No help topic for...", but still exited 0. This
makes it easier to script around apps built using `cli` since they can trust
that a 0 exit code indicated a successful execution.
- cleanups based on [Go Report Card
feedback](https://goreportcard.com/report/github.com/urfave/cli)
## [1.16.1] - 2016-08-28
### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
## [1.16.0] - 2016-05-02
### Added
- `Hidden` field on all flag struct types to omit from generated help text
### Changed
- `BashCompletionFlag` (`--enable-bash-completion`) is now omitted from
generated help text via the `Hidden` field
### Fixed
- handling of error values in `HandleAction` and `HandleExitCoder`
## [1.15.0] - 2016-04-30
### Added
- This file!
- Support for placeholders in flag usage strings
- `App.Metadata` map for arbitrary data/state management
- `Set` and `GlobalSet` methods on `*cli.Context` for altering values after
parsing.
- Support for nested lookup of dot-delimited keys in structures loaded from
YAML.
### Changed
- The `App.Action` and `Command.Action` now prefer a return signature of
`func(*cli.Context) error`, as defined by `cli.ActionFunc`. If a non-nil
`error` is returned, there may be two outcomes:
- If the error fulfills `cli.ExitCoder`, then `os.Exit` will be called
automatically
- Else the error is bubbled up and returned from `App.Run`
- Specifying an `Action` with the legacy return signature of
`func(*cli.Context)` will produce a deprecation message to stderr
- Specifying an `Action` that is not a `func` type will produce a non-zero exit
from `App.Run`
- Specifying an `Action` func that has an invalid (input) signature will
produce a non-zero exit from `App.Run`
### Deprecated
- <a name="deprecated-cli-app-runandexitonerror"></a>
`cli.App.RunAndExitOnError`, which should now be done by returning an error
that fulfills `cli.ExitCoder` to `cli.App.Run`.
- <a name="deprecated-cli-app-action-signature"></a> the legacy signature for
`cli.App.Action` of `func(*cli.Context)`, which should now have a return
signature of `func(*cli.Context) error`, as defined by `cli.ActionFunc`.
### Fixed
- Added missing `*cli.Context.GlobalFloat64` method
## [1.14.0] - 2016-04-03 (backfilled 2016-04-25)
### Added
- Codebeat badge
- Support for categorization via `CategorizedHelp` and `Categories` on app.

"""
The flag types that ship with the cli library have many things in common, and
so we can take advantage of the `go generate` command to create much of the
source code from a list of definitions. These definitions attempt to cover
the parts that vary between flag types, and should evolve as needed.
An example of the minimum definition needed is:
{
"name": "SomeType",
"type": "sometype",
"context_default": "nil"
}
In this example, the code generated for the `cli` package will include a type
named `SomeTypeFlag` that is expected to wrap a value of type `sometype`.
Fetching values by name via `*cli.Context` will default to a value of `nil`.
A more complete, albeit somewhat redundant, example showing all available
definition keys is:
{
"name": "VeryMuchType",
"type": "*VeryMuchType",
"value": true,
"dest": false,
"doctail": " which really only wraps a []float64, oh well!",
"context_type": "[]float64",
"context_default": "nil",
"parser": "parseVeryMuchType(f.Value.String())",
"parser_cast": "[]float64(parsed)"
}
The meaning of each field is as follows:
name (string) - The type "name", which will be suffixed with
`Flag` when generating the type definition
for `cli` and the wrapper type for `altsrc`
type (string) - The type that the generated `Flag` type for `cli`
is expected to "contain" as its `.Value` member
value (bool) - Should the generated `cli` type have a `Value`
member?
dest (bool) - Should the generated `cli` type support a
destination pointer?
doctail (string) - Additional docs for the `cli` flag type comment
context_type (string) - The literal type used in the `*cli.Context`
reader func signature
context_default (string) - The literal value used as the default by the
`*cli.Context` reader funcs when no value is
present
parser (string) - Literal code used to parse the flag `f`,
expected to have a return signature of
(value, error)
parser_cast (string) - Literal code used to cast the `parsed` value
returned from the `parser` code
