## [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
