rezplugins.shell.cmd

Windows Command Prompt (DOS) shell.

class rezplugins.shell.cmd.CMD[source]

Bases: rez.shells.Shell

alias(key, value)[source]
command(value)[source]
comment(value)[source]
error(value)[source]
escape_string(value, is_path=False)[source]

Escape the <, >, ^, and & special characters reserved by Windows.

Parameters

value (str/EscapedString) – String or already escaped string.

Returns

The value escaped for Windows.

Return type

str

expand_env_vars = True
classmethod file_extension()[source]

Get the file extension associated with the shell.

Returns

Shell file extension.

Return type

str

classmethod get_all_key_tokens(key)[source]

Encodes the environment variable into the shell specific forms. Shells might implement multiple forms, but the most common/safest should be always returned at index 0.

Parameters

key – Variable name to encode

Returns

list of str with encoded token forms

get_output(style=<OutputStyle.file: ('Code as it would appear in a script file.', )>)[source]

Returns any implementation specific data.

Parameters

style (OutputStyle) – Style affecting output format.

Returns

Depends on implementation, but usually a code string.

classmethod get_startup_sequence(rcfile, norc, stdin, command)[source]
classmethod get_syspaths()[source]
info(value)[source]
classmethod join(command)[source]

Note: Default to unix sh/bash- friendly behaviour.

Parameters

command – A sequence of program arguments to be joined into a single string that can be executed in the current shell.

Returns

A string object representing the command.

classmethod line_terminator()[source]
Returns

default line terminator

Return type

str

classmethod name()[source]

Plugin name.

normalize_path(path)[source]

Normalize a path.

Change path to a valid filepath representation for this interpreter.

IMPORTANT: Because var references like ${THIS} might be passed to funcs like appendvar, path might be in this form. You need to take that into account (ie, ensure normalization doesn’t break such a var reference).

Parameters

path (str) – A filepath which may be in posix format, or windows format, or some combination of the two. For eg, a string like {root}/bin on windows will evaluate to C:.../bin - in this case, the cmd shell would want to normalize this and convert to all forward slashes.

Returns

The normalized path.

Return type

str

resetenv(key, value, friends=None)[source]
setenv(key, value)[source]
shebang()[source]

spawn_shell(context_file, tmpdir, rcfile=None, norc=False, stdin=False, command=None, env=None, quiet=False, pre_command=None, add_rez=True, **Popen_args)[source]

Spawn a possibly interactive subshell. :param context: _file File that must be sourced in the new shell, this

configures the Rez environment.

Parameters
  • tmpdir – Tempfiles, if needed, should be created within this path.

  • rcfile – Custom startup script.

  • norc – Don’t run startup scripts. Overrides rcfile.

  • stdin – If True, read commands from stdin in a non-interactive shell. If a different non-False value, such as subprocess.PIPE, the same occurs, but stdin is also passed to the resulting subprocess.Popen object.

  • command – If not None, execute this command in a non-interactive shell. If an empty string, don’t run a command, but don’t open an interactive shell either.

  • env – Environ dict to execute the shell within; uses the current environment if None.

  • quiet – If True, don’t show the configuration summary, and suppress any stdout from startup scripts.

  • pre_command – Command to inject before the shell command itself. This is for internal use.

  • add_rez – If True, assume this shell is being used with rez, and do things such as set the prompt etc.

  • package_commands_sourced_first – If True, source the context file before sourcing startup scripts (such as .bashrc). If False, source the context file AFTER. If None, use the configured setting.

  • popen_args – args to pass to the shell process object constructor.

Returns

A subprocess.Popen object representing the shell process.

classmethod startup_capabilities(rcfile=False, norc=False, stdin=False, command=False)[source]

Given a set of options related to shell startup, return the actual options that will be applied. @returns 4-tuple representing applied value of each option.
