# Change Log
|
||||
|
||||
**ATTN**: This project uses [semantic versioning](http://semver.org/).
|
||||
|
||||
## 2.0.0 - (unreleased 2.x series)
|
||||
### Added
|
||||
- `NewStringSlice` and `NewIntSlice` for creating their related types
|
||||
- `Float64SliceFlag` for unmarshaling a list of floats from the user
|
||||
- `Context.Lineage` to get all contexts from current up to global
|
||||
- `Context.LocalFlagNames` to get the flag names from *only* the current context
|
||||
- `BoolFlag.Value` to handle both default-false and default-true
|
||||
|
||||
### Changed
|
||||
- `Context.FlagNames` now returns all flags in the context lineage
|
||||
- `Context.IsSet` now considers the full context lineage
|
||||
|
||||
### Removed
|
||||
- the ability to specify `&StringSlice{...string}` or `&IntSlice{...int}`.
|
||||
To migrate to the new API, you may choose to run [the migrator
|
||||
(python) script](./cli-v1-to-v2).
|
||||
- The optimistic reordering of arguments and flags introduced by
|
||||
https://github.com/codegangsta/cli/pull/36. This behavior only worked when
|
||||
all arguments appeared before all flags, but caused [weird issues with boolean
|
||||
flags](https://github.com/codegangsta/cli/issues/103) and [reordering of the
|
||||
arguments](https://github.com/codegangsta/cli/issues/355) when the user
|
||||
attempted to mix flags and arguments. Given the trade-offs we removed support
|
||||
for this reordering.
|
||||
- adapter code for deprecated `Action` func signature
|
||||
- deprecated `App.Author`, `App.Email`, and `Command.ShortName` fields
|
||||
- All `Context.Global*` methods, as the non-global versions now traverse up
|
||||
the context lineage automatically.
|
||||
- `Context.Parent` method, as this is now available via `Context.Lineage`
|
||||
- `BoolTFlag` and related code, as this is now available via `BoolFlag.Value`
|
||||
|
||||
## [Unreleased] - (1.x series)
|
||||
### Added
|
||||
|
||||
### Changed
|
||||
|
||||
### Removed
|
||||
|
||||
### Fixed
|
||||
|
||||
### Deprecated
|
||||
|
||||
### Security
|
||||
|
||||
## [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
|
||||
|
||||

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
