xonsh.history.main#
Main entry points of the xonsh history.
- class xonsh.history.main.HistoryAlias(threadable=True, **kwargs)[source]#
Try ‘history <command> –help’ for more info
- exception Error(message: str, errno=1)#
Special case, when raised, the traceback will not be shown. Instead the process with exit with error code and message
- with_traceback()#
Exception.with_traceback(tb) – set self.__traceback__ to tb and return self.
- args#
- create_parser(func=None, has_args=False, allowed_params=None, **kwargs)#
create root parser
- static diff(a, b, reopen=False, verbose=False, _stdout=None)[source]#
Diff two xonsh history files
- Parameters
- left:
The first file to diff
- right:
The second file to diff
- reopen: -r, –reopen
make lazy file loading reopen files each time
- verbose: -v, –verbose
whether to print even more information
- err(*args, **kwargs)#
Write text to error stream
- static gc(size: Optional[Tuple[int, str]] = None, force=False, blocking=True)[source]#
Launches a new history garbage collector
- Parameters
- size-s, –size
Next two arguments represent the history size and units; e.g. “–size 8128 commands”
- force-f, –force
perform garbage collection even if history much bigger than configured limit
- blocking-n, –non-blocking
makes the gc non-blocking, and thus return sooner. By default it runs on main thread blocking input.
- hook_post_add_argument(action, param, func, **_)[source]#
Hook into parser.add_argument step.
Can be used to update action’s attributes
- hook_pre_add_argument(param: str, func, flags, kwargs)#
Hook to update arguments that are passed to parser.add_argument
- static info(to_json=False, _stdout=None)[source]#
Display information about the current history
- Parameters
- to_json: -j, –json
print in JSON format
- out(*args, **kwargs)#
Write text to output stream
- show(session: str = 'session', slices: Optional[List[int]] = None, datetime_format: Optional[str] = None, start_time: Optional[str] = None, end_time: Optional[str] = None, location: Optional[str] = None, reverse=False, numerate=False, timestamp=False, null_byte=False, _stdout=None, _stderr=None, _unparsed=None)[source]#
Display history of a session, default command
- Parameters
- session:
The history session to get. (all is an alias for xonsh)
- slices:
integer or slice notation to get only portions of history.
- datetime_format-f
the datetime format to be used for filtering and printing
- start_time: –start-time, +T
show only commands after timestamp
- end_time: -T, –end-time
show only commands before timestamp
- location: -l, –location
The history file location (bash or zsh)
- reverse: -r, –reverse
Reverses the direction
- numerate: -n, –numerate
Numerate each command
- timestamp: -t, –ts, –time-stamp
show command timestamps
- null_byte: -0, –nb, –null-byte
separate commands by the null character for piping history to external filters
- _unparsed
remaining args from
parser.parse_known_args
- transfer(source: str, source_file: Optional[str] = None, target: Optional[str] = None, target_file: Optional[str] = None)[source]#
Transfer entries between history backends.
- Parameters
- source
Name of the source history backend
- source_file–source-file, –sf
Override the default location of the history file of the backend.
- target–target, -t
Name of the target history backend. (default: $XONSH_HISTORY_BACKEND)
- target_file–target-file, –tf
Path to the location of the history file.
Notes
It will not remove duplicate entries, use $HISTCONTROL for managing such entries.
