* Avoid raising errors while running help for custom commands
Raising an error from the help command is not a pleasure for the
end user, even if the command does not define any attributes
* Update test/irb/command/test_custom_command.rb

* Use 'irbtest-' instead if 'irb-' as prefix of test files.
Otherwise IRB would mis-recognize exceptions raised in test files as
exceptions raised in IRB itself.
* Support `IRB.conf[:BACKTRACE_FILTER]``
This config allows users to customize the backtrace of exceptions raised
and displayed in IRB sessions. This is useful for filtering out library
frames from the backtrace.
IRB expects the given value to response to `call` method and return
the filtered backtrace.

Since commands can't be chained with methods, their return values are
not intended to be used. But if IRB keeps storing command return values
as the last value, and print them, users may rely on such implicit
behaviour.
So to avoid such confusion, this commit suppresses command's
return values. It also updates some commands that currently rely on
this implicit behaviour.

as names
(https://github.com/ruby/irb/pull/932)
This will save users some heads scratching when they try to register a
command with a string name and found that it doesn't work.
I also rewrote converted custom command tests into integration tests to
make test setup/cleanup easier.
https://github.com/ruby/irb/commit/a91a212dbe
Some helpers, like Rails console's `app`, requires memoization of the
helper's ivars. To support it IRB needs to memoize helper method instances
as well.
https://github.com/ruby/irb/commit/169a9a2c30
(https://github.com/ruby/irb/pull/925)
This module was used to extend both commands and helpers when they're not
separated. Now that they are, and we have a Command module, we should move
command-related logic to the Command module and update related references.
This will make the code easier to understand and refactor in the future.

* Remove exit and exti! command workaround when executed outside of IRB
Command was a method. It could be executed outside of IRB.
Workaround for it is no longer needed.
* Handle IRB_EXIT in debug mode
* Add exit and exit! command in rdbg mode
https://github.com/ruby/irb/commit/0b5dd6afd0
(https://github.com/ruby/irb/pull/886)
This is a feature that has been requested for a long time. It is now
possible to define custom commands in IRB.
Example usage:
```ruby
require "irb/command"
class HelloCommand < IRB::Command::Base
description "Prints hello world"
category "My commands"
help_message "It doesn't do more than printing hello world."
def execute
puts "Hello world"
end
end
IRB::Command.register(:hello, HelloCommand)
```
https://github.com/ruby/irb/commit/888643467c
(https://github.com/ruby/irb/pull/920)
This has a few benefits:
- We can keep hiding the evaluation logic inside the Context level, which
has always been the convention until #824 was merged recently.
- Although not an official API, gems like `debug` and `mission_control-jobs`
patch `Context#evaluate` to wrap their own logic around it. This implicit
contract was broken after #824, and this change restores it.
In addition to the refactor, I also converted some context-level evaluation
tests into integration tests, which are more robust and easier to maintain.
https://github.com/ruby/irb/commit/b32aee4068

(https://github.com/ruby/irb/pull/901)
* Always save irb_history in HOME or XDG_CONFIG_HOME
Also split irbrc search logic from irb_history search logic as a refactor
* Remove IRB.conf[:RC_NAME_GENERATOR] because it's not configurable
This conf is used to specify which irbrc to load. Need to configure before irbrc is loaded, so it's actually not configurable.
This conf is also used for history file search, but it is configurable by conf[:HISTORY_FILE].
* remove rc_file_test because it is tested with rc_files, remove useless test setup
* Make internal irbrc searching method private
https://github.com/ruby/irb/commit/11d03a6ff7
(https://github.com/ruby/irb/pull/893)
Some cases of it currently create `~/.irb_history` files unintentionally
while others don't. This is caused by the varying levels of setup/cleanup between
them. This commit fixes the issue by wrapping every single test inside a
consistent test setup and teardown callbacks.
https://github.com/ruby/irb/commit/a2a3cbb0ef
(https://github.com/ruby/irb/pull/888)
* Remove dead irb_level method
* Restructure workspace management
Currently, workspace is an attribute of IRB::Context in most use cases.
But when some workspace commands are used, like `pushws` or `popws`, a
workspace will be created and used along side with the original workspace
attribute.
This complexity is not necessary and will prevent us from expanding
multi-workspace support in the future.
So this commit introduces a @workspace_stack ivar to IRB::Context so IRB
can have a more natural way to manage workspaces.
* Fix pushws without args
* Always display workspace stack after related commands are used
https://github.com/ruby/irb/commit/61560b99b3
(https://github.com/ruby/irb/pull/877)
* Make help command display help for individual commands
Usage: `help [command]`
If the command is not specified, it will display a list of all available commands.
If the command is specified, it will display the banner OR description of the command.
If the command is not found, it will display a message saying that the command is not found.
* Rename test/irb/cmd to test/irb/command
* Add banner to edit and ls commands
* Promote help command in the help message
1. Make `show_cmds` an alias of `help` so it's not displayed in the help message
2. Update description of the help command to reflect `help <command>` syntax
* Rename banner to help_message
https://github.com/ruby/irb/commit/43a2c99f3f
(https://github.com/ruby/irb/pull/873)
* Replace ExtendCommand with Command and standardize command related names
1. Rename lib/irb/extend-command.rb to lib/irb/command.rb
2. Rename lib/irb/cmd/*.rb to lib/irb/command/*.rb
3. Rename test/irb/test_cmd.rb to test/irb/test_command.rb
4. Rename ExtendCommand to Command
* Alias ExtendCommand to Command and deprecate it
* Rename Command::Nop to Command::Base
* Not deprecate old constants just yet
* Add lib/irb/cmd/nop.rb back
https://github.com/ruby/irb/commit/462c1284af
to it
(https://github.com/ruby/irb/pull/856)
* Test IRB's behaviour with empty input
* Handle empty input and pass it to debugger
Since `rdbg` accepts empty input to repeat the previous command, IRB
should take empty input in `irb:rdbg` sessions and pass them to the
debugger.
Currently, IRB simply ignores empty input and does nothing. This commit
creates `EmptyInput` to represent empty input so it can fit into the
current IRB's input processing flow in `Irb#eval_input`.
https://github.com/ruby/irb/commit/0e9db419be
```
test.rb:1:in 'Object#toplevel_meth': unhandled exception
from test.rb:4:in 'Foo.class_meth'
from test.rb:6:in 'Foo#instance_meth'
from test.rb:11:in 'singleton_meth'
from test.rb:13:in '<main>'
```
[Feature #19117]
(https://github.com/ruby/irb/pull/869)
Currently, if the signature's constant part is not defined, a NameError
would be raised.
```
irb(main):001> show_source Foo
(eval):1:in `<top (required)>': uninitialized constant Foo (NameError)
Foo
^^^
from (irb):1:in `<main>'
```
This commit fixes the issue and simplifies the `edit` command's implementation.
https://github.com/ruby/irb/commit/8c16e029d1
(https://github.com/ruby/irb/pull/862)
* Powerup show_source by enabling RubyVM.keep_script_lines
* Add file_content field to avoid reading file twice while show_source
* Change path passed to eval, don't change irb_path.
* Encapsulate source coloring logic and binary file check insode class Source
* Add edit command testcase when irb_path does not exist
* Memoize irb_path existence to reduce file existence check calculating eval_path
https://github.com/ruby/irb/commit/239683a937
(https://github.com/ruby/irb/pull/867)
* Remove IRB.irb_exit! method
It's not necessary to introduce a new method just for the exit! command
at this moment.
* Rename ExitForcedAction to ForceExit
* Move force exit tests to a dedicated file
* Fix nested history saving with exit! command
Because we switched to use `Kernel#exit` instead of `exit!`, the outer
session's ensure block in `Irb#run` will be run, which will save the
history. This means the separate check to save history when force exiting
is no longer necessary.
* execute_lines helper should also capture IRB setup's output
This prevents setup warnings from being printed to test output
while allowing those output to be tested.
* Update readme
https://github.com/ruby/irb/commit/899d10ade1
(https://github.com/ruby/irb/pull/851)
* Added failing test for when writing history on exit
* Save history on exit
* Exit early when calling Kernel.exit
* use status 0 for kernel.exit
* Added test for nested sessions
* Update lib/irb.rb
