|
||||
|
||||
= What's shell.rb?
|
||||
|
||||
It realizes a wish to do execution of commands with filters and pipes
|
||||
like sh/csh by using just native facilities of ruby.
|
||||
|
||||
= Main classes
|
||||
|
||||
== Shell
|
||||
|
||||
Every shell object has its own current working directory, and executes
|
||||
each command as if it stands in the directory.
|
||||
|
||||
--- Shell#cwd
|
||||
--- Shell#dir
|
||||
--- Shell#getwd
|
||||
--- Shell#pwd
|
||||
|
||||
Returns the current directory
|
||||
|
||||
--- Shell#system_path
|
||||
|
||||
Returns the command search path in an array
|
||||
|
||||
--- Shell#umask
|
||||
|
||||
Returns the umask
|
||||
|
||||
== Filter
|
||||
|
||||
Any result of command exection is a Filter. Filter include
|
||||
Enumerable, therefore a Filter object can use all Enumerable
|
||||
facilities.
|
||||
|
||||
= Main methods
|
||||
|
||||
== Command definitions
|
||||
|
||||
In order to execute a command on your OS, you need to define it as a
|
||||
Shell method.
|
||||
|
||||
Alternatively, you can execute any command via Shell#system even if it
|
||||
is not defined.
|
||||
|
||||
--- Shell.def_system_command(command, path = command)
|
||||
|
||||
Defines a command. Registers <path> as a Shell method
|
||||
<command>.
|
||||
|
||||
ex)
|
||||
Shell.def_system_command "ls"
|
||||
Defines ls.
|
||||
|
||||
Shell.def_system_command "sys_sort", "sort"
|
||||
Defines sys_sort as sort.
|
||||
|
||||
--- Shell.undef_system_command(command)
|
||||
|
||||
Undefines a commmand
|
||||
|
||||
--- Shell.alias_command(ali, command, *opts) {...}
|
||||
|
||||
Aliases a command.
|
||||
|
||||
ex)
|
||||
Shell.alias_command "lsC", "ls", "-CBF", "--show-control-chars"
|
||||
Shell.alias_command("lsC", "ls"){|*opts| ["-CBF", "--show-control-chars", *opts]}
|
||||
|
||||
--- Shell.unalias_command(ali)
|
||||
|
||||
Unaliases a command.
|
||||
|
||||
--- Shell.install_system_commands(pre = "sys_")
|
||||
|
||||
Defines all commands in the default_system_path as Shell method,
|
||||
all with <pre> prefixed to their names.
|
||||
|
||||
== Creation
|
||||
|
||||
--- Shell.new
|
||||
|
||||
Creates a Shell object which current directory is set to the
|
||||
process current directory.
|
||||
|
||||
--- Shell.cd(path)
|
||||
|
||||
Creates a Shell object which current directory is set to
|
||||
<path>.
|
||||
|
||||
== Process management
|
||||
|
||||
--- Shell#jobs
|
||||
|
||||
Returns a list of scheduled jobs.
|
||||
|
||||
--- Shell#kill sig, job
|
||||
|
||||
Sends a signal <sig> to <job>.
|
||||
|
||||
== Current directory operations
|
||||
|
||||
--- Shell#cd(path, &block)
|
||||
--- Shell#chdir
|
||||
|
||||
Changes the current directory to <path>. If a block is given,
|
||||
it restores the current directory when the block ends.
|
||||
|
||||
--- Shell#pushd(path = nil, &block)
|
||||
--- Shell#pushdir
|
||||
|
||||
Pushes the current directory to the directory stack, changing
|
||||
the current directory to <path>. If <path> is omitted, it
|
||||
exchanges its current directory and the top of its directory
|
||||
stack. If a block is given, it restores the current directory
|
||||
when the block ends.
|
||||
|
||||
--- Shell#popd
|
||||
--- Shell#popdir
|
||||
|
||||
Pops a directory from the directory stack, and sets the current
|
||||
directory to it.

|
||||

|
||||
