translate from japanese by gotoken-san
|
||||||
|
|
||||||
|
==begin
|
||||||
|
= What is irb?
|
||||||
|
|
||||||
|
irb stands for `interactive ruby'. irb is a tool to execute interactively
|
||||||
|
ruby expressions read from stdin.
|
||||||
|
|
||||||
|
= Invoking
|
||||||
|
|
||||||
|
% ruby -r irb -e0
|
||||||
|
% irb
|
||||||
|
|
||||||
|
Either of the aboves. In the former style, options can be specified
|
||||||
|
as follows:
|
||||||
|
|
||||||
|
% ruby -r irb -e0 -- -v
|
||||||
|
|
||||||
|
= Usage
|
||||||
|
|
||||||
|
Use of irb is easy if you know ruby. Executing irb, prompts are
|
||||||
|
displayed as follows. Then, enter expression of ruby. A input is
|
||||||
|
executed when it is syntacticaly completed.
|
||||||
|
|
||||||
|
dim% irb
|
||||||
|
irb(main):001:0> 1+2
|
||||||
|
3
|
||||||
|
irb(main):002:0> class Foo
|
||||||
|
irb(main):003:1> def foo
|
||||||
|
irb(main):004:2> print 1
|
||||||
|
irb(main):005:2> end
|
||||||
|
irb(main):006:1> end
|
||||||
|
nil
|
||||||
|
irb(main):007:0>
|
||||||
|
|
||||||
|
And, Readline extesion module can be used with irb. Using Readline
|
||||||
|
is the standard default action if Readline is installed.
|
||||||
|
|
||||||
|
= Command line option
|
||||||
|
|
||||||
|
irb.rb [options] file_name opts
|
||||||
|
options:
|
||||||
|
-f suppress read ~/.irbrc
|
||||||
|
-m bc mode (fraction or matrix are available)
|
||||||
|
-d set $DEBUG to true (same as `ruby -d')
|
||||||
|
-r load-module same as `ruby -r'
|
||||||
|
--inspect uses `inspect' for output (the default except bc mode)
|
||||||
|
--noinspect doesn't uses inspect for output
|
||||||
|
--readline uses Readline extension module
|
||||||
|
--noreadline doesn't use Readline extension module
|
||||||
|
--prompt prompt-mode
|
||||||
|
--prompt-mode prompt-mode
|
||||||
|
switches prompt mode. Pre-defined prompt modes are
|
||||||
|
`defalut', `simple', `xmp' and `inf-ruby'
|
||||||
|
|
||||||
|
--inf-ruby-mode uses prompt appreciate for inf-ruby-mode on emacs.
|
||||||
|
Suppresses --readline.
|
||||||
|
--simple-prompt simple prompt mode
|
||||||
|
--noprompt no prompt
|
||||||
|
--tracer display trace for each execution of commands.
|
||||||
|
--back-trace-limit n
|
||||||
|
displayes backtrace top n and tail n. The default
|
||||||
|
value is 16.
|
||||||
|
--irb_debug n sets internal debug level to n (It shouldn't be used)
|
||||||
|
-v, --version prints the version of irb
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
= Configurations
|
||||||
|
|
||||||
|
irb reads `~/.irbrc' when it is invoked. If `~/.irbrb' doesn't exist
|
||||||
|
irb try to read in the order `.irbrc', `irb.rc', `_irbrc' then `$irbrc'.
|
||||||
|
|
||||||
|
The following is altanative to the command line option. To use them
|
||||||
|
type as follows in an irb session.
|
||||||
|
|
||||||
|
IRB.conf[:IRB_NAME]="irb"
|
||||||
|
IRB.conf[:MATH_MODE]=false
|
||||||
|
IRB.conf[:USE_TRACER]=false
|
||||||
|
IRB.conf[:USE_LOADER]=false
|
||||||
|
IRB.conf[:IGNORE_SIGINT]=true
|
||||||
|
IRB.conf[:IGNORE_EOF]=false
|
||||||
|
IRB.conf[:INSPECT_MODE]=nil
|
||||||
|
IRB.conf[:IRB_RC] = nil
|
||||||
|
IRB.conf[:BACK_TRACE_LIMIT]=16
|
||||||
|
IRB.conf[:USE_LOADER] = false
|
||||||
|
IRB.conf[:USE_READLINE] = nil
|
||||||
|
IRB.conf[:USE_TRACER] = false
|
||||||
|
IRB.conf[:IGNORE_SIGINT] = true
|
||||||
|
IRB.conf[:IGNORE_EOF] = false
|
||||||
|
IRB.conf[:PROMPT_MODE] = :DEFALUT
|
||||||
|
IRB.conf[:PROMPT] = {...}
|
||||||
|
IRB.conf[:DEBUG_LEVEL]=0
|
||||||
|
IRB.conf[:VERBOSE]=true
|
||||||
|
|
||||||
|
== Customizing prompt
|
||||||
|
|
||||||
|
To costomize the prompt you set a variable
|
||||||
|
|
||||||
|
IRB.conf[:PROMPT]
|
||||||
|
|
||||||
|
For example, describe as follows in `.irbrc'.
|
||||||
|
|
||||||
|
IRB.conf[:PROMPT][:MY_PROMPT] = { # name of prompt mode
|
||||||
|
:PROMPT_I => nil, # normal prompt
|
||||||
|
:PROMPT_S => nil, # prompt for continuated strings
|
||||||
|
:PROMPT_C => nil, # prompt for continuated statement
|
||||||
|
:RETURN => " ==>%s\n" # format to return value
|
||||||
|
}
|
||||||
|
|
||||||
|
Then, invoke irb with the above prompt mode by
|
||||||
|
|
||||||
|
% irb --prompt my-prompt
|
||||||
|
|
||||||
|
Or add the following in `.irbrc'.
|
||||||
|
|
||||||
|
IRB.conf[:PROMPT_MODE] = :MY_PROMPT
|
||||||
|
|
||||||
|
Constants PROMPT_I, PROMPT_S and PROMPT_C specifies the format.
|
||||||
|
In the prompt specification, some special strings are available.
|
||||||
|
|
||||||
|
%N command name which is running
|
||||||
|
%m to_s of main object (self)
|
||||||
|
%M inspect of main object (self)
|
||||||
|
%l type of string(", ', /, ]), `]' is inner %w[...]
|
||||||
|
%NNi indent level. NN is degits and means as same as printf("%NNd").
|
||||||
|
It can be ommited
|
||||||
|
%NNn line number.
|
||||||
|
%% %
|
||||||
|
|
||||||
|
For instance, the default prompt mode is defined as follows:
|
||||||
|
|
||||||
|
IRB.conf[:PROMPT_MODE][:DEFAULT] = {
|
||||||
|
:PROMPT_I => "%N(%m):%03n:%i> ",
|
||||||
|
:PROMPT_S => "%N(%m):%03n:%i%l ",
|
||||||
|
:PROMPT_C => "%N(%m):%03n:%i* ",
|
||||||
|
:RETURN => "%s\n"
|
||||||
|
}
|
||||||
|
|
||||||
|
RETURN is used to printf.
|
||||||
|
|
||||||
|
== Configurating subirb
|
||||||
|
|
||||||
|
The command line option or IRB.conf specify the default behavior of
|
||||||
|
(sub)irb. On the other hand, each conf of in the next sction `6. Command'
|
||||||
|
is used to individually configurate (sub)irb.
|
||||||
|
|
||||||
|
If proc is set to IRB.conf[:IRB_RC], its subirb will be invoked after
|
||||||
|
execution of that proc under giving the context of irb as its
|
||||||
|
aregument. By this mechanism each subirb can be configurated.
|
||||||
|
|
||||||
|
= Command
|
||||||
|
|
||||||
|
For irb commands, both simple name and `irb_'-prefixed name are prepared.
|
||||||
|
|
||||||
|
--- exit, quit, irb_exit
|
||||||
|
Quits (sub)irb.
|
||||||
|
if you've done cb (see below), exit from the binding mode.
|
||||||
|
|
||||||
|
--- conf, irb_context
|
||||||
|
Displays current configuration. Modifing the configuration is
|
||||||
|
achieved by sending message to `conf'.
|
||||||
|
|
||||||
|
--- conf.back_trace_limit
|
||||||
|

= Restrictions
|
||||||
|
|
||||||
|
Because irb evaluates the inputs immediately after the imput is
|
||||||
|
syntactically completed, irb gives slight different result than
|
||||||
|
directly use ruby. Known difference is pointed out here.
|
||||||
|
|
||||||
|
|
||||||
|
== Declaration of the local variable
|
||||||
|
|
||||||
|
The following causes an error in ruby:
|
||||||
|
|
||||||
|
eval "foo = 0"
|
||||||
|
foo
|
||||||
|
--
|
||||||
|
-:2: undefined local variable or method `foo' for #<Object:0x40283118> (NameError)
|
||||||
|
---
|
||||||
|
NameError
|
||||||
|
|
||||||
|
Though, the above will successfully done by irb.
|
||||||
|
|
||||||
|
>> eval "foo = 0"
|
||||||
|
=> 0
|
||||||
|
>> foo
|
||||||
|
=> 0
|
||||||
|
|
||||||
|
Ruby evaluates a code after reading entire of code and determination
|
||||||
|
of the scope of local variables. On the other hand, irb do
|
||||||
|
immediately. More precisely, irb evaluate at first
|
||||||
|
|
||||||
|
evel "foo = 0"
|
||||||
|
|
||||||
|
then foo is defined on this timing. It is because of this
|
||||||
|
incompatibility.
|
||||||
|
|
||||||
|
If you'd like to detect those differences, begin...end can be used:
|
||||||
|
|
||||||
|
>> begin
|
||||||
|
?> eval "foo = 0"
|
||||||
|
>> foo
|
||||||
|
>> end
|
||||||
|
NameError: undefined local variable or method `foo' for #<Object:0x4013d0f0>
|
||||||
|
(irb):3
|
||||||
|
(irb_local_binding):1:in `eval'
|
||||||
|
|
||||||
|
== Here-document
|
||||||
|
|
||||||
|
Implementation of Here-document is incomplete.
|
||||||
|
|
||||||
|
== Symbol
|
||||||
|
|
||||||
|
Irb can not always recognize a symbol as to be Symbol. Concretely, an
|
||||||
|
expression have completed, however Irb regard it as continuation line.
