Parameters
----------
name : str
Name for the folder or file.

Parent of `self`. The default is `None`, meaning the object will
be the "root" of the directory.

objects children do not contain a fake item with the same name.
If those conditions are met, `self` is removed from the children
of its current parent, and its parent attribute is reassigned.
Depths are also reset.
Parameters
----------
other : seedir.fakedir.FakeDir
Fake directory to become the new `parent` for self.
Raises
------
TypeError
other is not a `seedir.fakedir.Fakedir`.
FakedirError

'''
Create a folder tree diagram for `self`. `seedir.fakedir.FakeDir` version of
`seedir.realdir.seedir()` (see its documentation for examples).
Parameters
----------
style : 'lines', 'dash', 'arrow', 'spaces', 'plus', or 'emoji', optional
Style to use. The default is `'lines'`. A style determines the set
of characters ("tokens") used to represent the base structure of
the directory (e.g. which items belong to which folders, when items
are the last member of a folder, etc.). The actual tokens being used
by each style can be viewed with `seedir.printing.get_styleargs()`.
printout : bool, optional
Print the folder structure in the console. The default is `True`. When
`False`, the folder diagram is returned as a string.
indent : int (>= 0), optional
Number of spaces separating items from their parent folder.
The default is `2`.
uniform : str or None, optional
Characters to use for all tokens when creating the tree diagram.
The default is `None`. When not `None`, the extend, space, split, and
final tokens are replaced with `uniform` (the `'spaces'` style is
essentially `uniform = ' '`).
anystart : str or None, optional
Characters to append before any item (i.e. folder or file). The
default is `None`. Specific starts for folders and files can be
specified (see `**kwargs`).
anyend : str or None, optional
Characters to append after any item (i.e. folder or file). The
default is `None`. Specific ends for folders and files can be
specified (see `**kwargs`).
depthlimit : int or None, optional
Limit the depth of folders to traverse. Folders at the `depthlimit` are
included, but their contents are not shown (with the exception of the
beyond parameter being specified). The default is `None`, which can
cause exceptionally long runtimes for deep or extensive directories.
itemlimit : int or None, optional
Limit the number of items in a directory to show. Items beyond the
`itemlimit` can be expressed using the `beyond` parameter. The files and
folders left out are determined by the sorting parameters
(`sort`, `sort_reverse`, `sort_key`). The default is `None`.
beyond : str ('ellipsis', 'content' or a string starting with an underscore) or None, optional
String to indicate directory contents beyond the `itemlimit` or the
`depthlimit`. The default is `None`. Options are: `'ellipsis'` (`'...'`),
`'content'` or `'contents'` (the number of files and folders beyond), or
a string starting with `'_'` (everything after the leading underscore
will be returned)
first : 'files', 'folders', or None, optional
Sort the directory so that either files or folders appear first.
The default is `None`.
sort : bool, optional
Sort the directory. With no other specifications, the sort will be a
simple alphabetical sort of the item names, but this can be altered
with the `first`, `sort_reverse`, and `sort_key parameters`.
The default is `False`.
sort_reverse : bool, optional
Reverse the sorting determined by `sort` or `sort_key`.
The default is `False`.
sort_key : function, optional
Key to use for sorting file or folder names, akin to the `key` parameter
of the builtin `sorted()` or `list.sort()`. The function should take a
string as an argument. The default is `None`.
include_folders, exclude_folders, include_files, exclude_files : str, list-like, or None, optional
Folder / file names to include or exclude. The default is `None`. By
default, these are interpreted literally. Pass `regex=True` for
using regular expressions.
regex : bool, optional
Interpret the strings of include/exclude file/folder arguments as
regular expressions. The default is `False`.
mask : function, optional
Function for filtering items. Each individual item object
is passed to the mask function. If `True` is returned, the
item is kept. The default is `None`.
formatter : function, optional
Function for customizing the directory printing logic and style
based on specific folders & files. When passed, the formatter
is called on each item in the file tree, and the current arguments
are updated based what is returned.
The formatter function should accept a FakeItem as a
single argument (either relative or absolute, depending on what is passed
to the `path` argument), and it should return either a dictionary or None.
The dictionary should have names of arguments as keys and their respective
setting as values.
The following options can meaningfully be toggled by passing a formatter
function: `depthlimit`, `itemlimit`, `beyond`, `first`, `sort`, `sort_reverse`,
`sort_key`, `include_folders`, `regex`, `mask`, as well as any seedir token
keywords (`extend`, `space`, `split`, `final`, `folderstart`, `filestart`,
`folderend`, `fileend`).
Note that in version 0.3.0, formatter could only be used to update
the style tokens. It can now be used to udpate those as well as the other
arguments listed above.
If None is returned by formatter, the tokens will be set by `style`.
Note that items exlcuded by the inclusion/exclusion arguments (or the
`mask`) *will not* be seen by formatter. Similarly, any folder tree
entries created by the `beyond` argument *will not* be seen by formatter.
sticky_formatter : bool, optional
When True, updates to argumnts made by the `formatter` (see above)
will be permanent. Thus, if arguments are updated when the `formatter`
is called on a folder, its children will (recursively) inherit
those new arguments.
slash : str, option:
**`DeprecationWarning`**: *With addition of `folderend` in v0.3.1,
`slash` is to be deprecated in a future version.*
Slash character to follow folders. If `'sep'`, uses `os.sep`. The
default is `'/'`.
**kwargs : str
Specific tokens to use for creating the file tree diagram. The tokens
use by each builtin style can be seen with `seedir.printing.get_styleargs()`.
Valid options are `extend` (characters to show the extension of a directory
while its children are traversed), `space` (character to provide the
correct indentation of an item when some of its parent / grandparent
directories are completely traversed), `split` (characters to show a
folder or file within a directory, with more items following),
`final` (characters to show a folder or file within a directory,
with no more items following), `folderstart` (characters to prepend
before any folder), `filestart` (characters to preppend before any
file), `folderend` (characters to append after any folder), and
`fileend` (characters to append after any file). The following shows
the default tokens for the `'lines'` style:
>>> import seedir as sd
>>> sd.get_styleargs('lines')
{'split': '├─', 'extend': '│ ', 'space': ' ', 'final': '└─', 'folderstart': '', 'filestart': '', 'folderend': '/', 'fileend': ''}
All default style tokens are 2 character strings, except for
the file/folder start/end tokens. Style tokens from `**kwargs` are not
affected by the indent parameter. The `uniform`, `anystart`, and
`anyend` parameters can be used to affect multiple style tokens.
Returns
-------
s (str) or None
The tree diagram (as a string) or None if prinout = True, in which
case the tree diagram is printed in the console.

Used by `seedir.fakedir.randomdir()`. Random dictionary names are chosen
for file and folder names.
Parameters
----------
fakedir : seedir.fakedir.FakeDir
Fake directory to populate.
depth : int, optional
Maximum depth to create folders and files. The default is `3`.
folders : int or collection of integers, optional
Parameter for setting the number of folders per directory.
The default is `2`. If `int`, represents the number of folders
per directory. If collection of integers, a random value will be
chosen from the collection each time a directory is popualted.
files : int or collection of integers, optional, optional
Same as the folders parameter, but for files.
stopchance : float between 0 and 1, optional
Chance that an added folder will not be populated. The default is `.5`.
seed : int or float, optional
Random seed. The default is `None`.
extensions : list-likie, optional
Collection of extensions to randomly select from for files. The
default is `['txt']`. Leading period can be included or omitted.
Raises
------
ValueError
Issue selecting int from folders or files.
Returns
-------
None, input is modified in place.

Parameters
----------
s : str
String representation a folder tree.
start_chars : str, optional
A string of characters which will be searched for as the start
of a folder or file name. The default is `None`, in which case the
characters are all letters, numbers, and punctuation marks except
for `/:?"*<>|` or `+=-`.
name_chars : str, optional
A string of characters which will be searched for as being part
of a file or folder name. The default is `None`, in which case the
characters are all letters, numbers, punctuation marks except
for `/:?"*<>|,` and spaces.
header_regex : str, optional
Regular expression to match the "header" of each line, i.e. the
structural characters of the folder diagram. The default is `None`.
If passed, the `start_chars` argument will be ignored. This and
`name_regex` are intended to provide functionality for parsing
specific or unusual cases.
name_regex : str, optional
Regular expression to match all the folder or file names.
The default is `None`.
If passed, the `start_chars` argument will be ignored.
supername : str, optional
Name to give the head directory if one cannot be found.
The default is `'FakeDir'`. This can happen when there is no clear
head directory in the string.
parse_comments : bool, optional
Try to parse and remove Python comments (following `#`).
The default is `True`.

Class to represent fake folders. Can be used to create custom folder tree diagrams. See
fakedir()
for converting a real directory into a FakeDir,fakedir_fromstring()
for converting a text folder diagram into aFakeDir
, andrandomdir()
for creating a random one.To make a

Parameters ---------- style : 'lines', 'dash', 'arrow', 'spaces', 'plus', or 'emoji', optional Style to use. The default is `'lines'`. A style determines the set of characters ("tokens") used to represent the base structure of the directory (e.g. which items belong to which folders, when items are the last member of a folder, etc.). The actual tokens being used by each style can be viewed with `seedir.printing.get_styleargs()`. printout : bool, optional Print the folder structure in the console. The default is `True`. When `False`, the folder diagram is returned as a string. indent : int (>= 0), optional Number of spaces separating items from their parent folder. The default is `2`. uniform : str or None, optional Characters to use for all tokens when creating the tree diagram. The default is `None`. When not `None`, the extend, space, split, and final tokens are replaced with `uniform` (the `'spaces'` style is essentially `uniform = ' '`). anystart : str or None, optional Characters to append before any item (i.e. folder or file). The default is `None`. Specific starts for folders and files can be specified (see `**kwargs`). anyend : str or None, optional Characters to append after any item (i.e. folder or file). The default is `None`. Specific ends for folders and files can be specified (see `**kwargs`). depthlimit : int or None, optional Limit the depth of folders to traverse. Folders at the `depthlimit` are included, but their contents are not shown (with the exception of the beyond parameter being specified). The default is `None`, which can cause exceptionally long runtimes for deep or extensive directories. itemlimit : int or None, optional Limit the number of items in a directory to show. Items beyond the `itemlimit` can be expressed using the `beyond` parameter. The files and folders left out are determined by the sorting parameters (`sort`, `sort_reverse`, `sort_key`). The default is `None`. beyond : str ('ellipsis', 'content' or a string starting with an underscore) or None, optional String to indicate directory contents beyond the `itemlimit` or the `depthlimit`. The default is `None`. Options are: `'ellipsis'` (`'...'`), `'content'` or `'contents'` (the number of files and folders beyond), or a string starting with `'_'` (everything after the leading underscore will be returned) first : 'files', 'folders', or None, optional Sort the directory so that either files or folders appear first. The default is `None`. sort : bool, optional Sort the directory. With no other specifications, the sort will be a simple alphabetical sort of the item names, but this can be altered with the `first`, `sort_reverse`, and `sort_key parameters`. The default is `False`. sort_reverse : bool, optional Reverse the sorting determined by `sort` or `sort_key`. The default is `False`. sort_key : function, optional Key to use for sorting file or folder names, akin to the `key` parameter of the builtin `sorted()` or `list.sort()`. The function should take a string as an argument. The default is `None`. include_folders, exclude_folders, include_files, exclude_files : str, list-like, or None, optional Folder / file names to include or exclude. The default is `None`. By default, these are interpreted literally. Pass `regex=True` for using regular expressions. regex : bool, optional Interpret the strings of include/exclude file/folder arguments as regular expressions. The default is `False`. mask : function, optional Function for filtering items. Each individual item object is passed to the mask function. If `True` is returned, the item is kept. The default is `None`. formatter : function, optional Function for customizing the directory printing logic and style based on specific folders & files. When passed, the formatter is called on each item in the file tree, and the current arguments are updated based what is returned. The formatter function should accept a FakeItem as a single argument (either relative or absolute, depending on what is passed to the `path` argument), and it should return either a dictionary or None. The dictionary should have names of arguments as keys and their respective setting as values. The following options can meaningfully be toggled by passing a formatter function: `depthlimit`, `itemlimit`, `beyond`, `first`, `sort`, `sort_reverse`, `sort_key`, `include_folders`, `regex`, `mask`, as well as any seedir token keywords (`extend`, `space`, `split`, `final`, `folderstart`, `filestart`, `folderend`, `fileend`). Note that in version 0.3.0, formatter could only be used to update the style tokens. It can now be used to udpate those as well as the other arguments listed above. If None is returned by formatter, the tokens will be set by `style`. Note that items exlcuded by the inclusion/exclusion arguments (or the `mask`) *will not* be seen by formatter. Similarly, any folder tree entries created by the `beyond` argument *will not* be seen by formatter. sticky_formatter : bool, optional When True, updates to argumnts made by the `formatter` (see above) will be permanent. Thus, if arguments are updated when the `formatter` is called on a folder, its children will (recursively) inherit those new arguments. slash : str, option: **`DeprecationWarning`**: *With addition of `folderend` in v0.3.1, `slash` is to be deprecated in a future version.* Slash character to follow folders. If `'sep'`, uses `os.sep`. The default is `'/'`. **kwargs : str Specific tokens to use for creating the file tree diagram. The tokens use by each builtin style can be seen with `seedir.printing.get_styleargs()`. Valid options are `extend` (characters to show the extension of a directory while its children are traversed), `space` (character to provide the correct indentation of an item when some of its parent / grandparent directories are completely traversed), `split` (characters to show a folder or file within a directory, with more items following), `final` (characters to show a folder or file within a directory, with no more items following), `folderstart` (characters to prepend before any folder), `filestart` (characters to preppend before any file), `folderend` (characters to append after any folder), and `fileend` (characters to append after any file). The following shows the default tokens for the `'lines'` style: >>> import seedir as sd >>> sd.get_styleargs('lines') {'split': '├─', 'extend': '│ ', 'space': ' ', 'final': '└─', 'folderstart': '', 'filestart': '', 'folderend': '/', 'fileend': ''} All default style tokens are 2 character strings, except for the file/folder start/end tokens. Style tokens from `**kwargs` are not affected by the indent parameter. The `uniform`, `anystart`, and `anyend` parameters can be used to affect multiple style tokens.

version ofseedir()
(see its documentation for examples).Parameters
style
:'lines', 'dash', 'arrow', 'spaces', 'plus',
or'emoji'
, optional- Style to use. The default is
'lines'
. A style determines the set of characters ("tokens") used to represent the base structure of the directory (e.g. which items belong to which folders, when items are the last member of a folder, etc.). The actual tokens being used by each style can be viewed withget_styleargs()
. printout
:bool
, optional- Print the folder structure in the console. The default is
True
. WhenFalse
, the folder diagram is returned as a string. indent
:int (>= 0)
, optional- Number of spaces separating items from their parent folder.
The default is
2
. uniform
:str
orNone
, optional- Characters to use for all tokens when creating the tree diagram.
The default is
None
. When notNone
, the extend, space, split, and final tokens are replaced withuniform
(the'spaces'
style is essentiallyuniform = ' '
). anystart
:str
orNone
, optional- Characters to append before any item (i.e. folder or file).
The
default is
None
. Specific starts for folders and files can be specified (see**kwargs
). anyend
:str
orNone
, optional- Characters to append after any item (i.e. folder or file).
The
default is
None
. Specific ends for folders and files can be specified (see**kwargs
). depthlimit
:int
orNone
, optional- Limit the depth of folders to traverse.
Folders at the
depthlimit
are included, but their contents are not shown (with the exception of the beyond parameter being specified). The default isNone
, which can cause exceptionally long runtimes for deep or extensive directories. itemlimit
:int
orNone
, optional- Limit the number of items in a directory to show.
Items beyond the
itemlimit
can be expressed using thebeyond
parameter. The files and folders left out are determined by the sorting parameters (sort
,sort_reverse
,sort_key
). The default isNone
. beyond
:str ('ellipsis', 'content'
ora string starting with an underscore)
orNone
, optional- String to indicate directory contents beyond the
itemlimit
or thedepthlimit
. The default isNone
. Options are:'ellipsis'
('...'
),'content'
or'contents'
(the number of files and folders beyond), or a string starting with'_'
(everything after the leading underscore will be returned) first
:'files', 'folders',
orNone
, optional- Sort the directory so that either files or folders appear first.
The default is
None
. sort
:bool
, optional- Sort the directory. With no other specifications, the sort will be a
simple alphabetical sort of the item names, but this can be altered
with the
first
,sort_reverse
, andsort_key parameters
. The default isFalse
. sort_reverse
:bool
, optional- Reverse the sorting determined by
sort
orsort_key
. The default isFalse
. sort_key
:function
, optional- Key to use for sorting file or folder names, akin to the
key
parameter of the builtinsorted()
orlist.sort()
. The function should take a string as an argument. The default isNone
. include_folders
,exclude_folders
,include_files
,exclude_files
:str, list-like,
orNone
, optional- Folder / file names to include or exclude. The default is
None
. By default, these are interpreted literally. Passregex=True
for using regular expressions. regex
:bool
, optional- Interpret the strings of include/exclude file/folder arguments as
regular expressions. The default is
False
. mask
:function
, optional- Function for filtering items.
Each individual item object
is passed to the mask function.
If
True
is returned, the item is kept. The default isNone
. formatter
:function
, optional-
Function for customizing the directory printing logic and style based on specific folders & files. When passed, the formatter is called on each item in the file tree, and the current arguments are updated based what is returned.
The formatter function should accept a FakeItem as a single argument (either relative or absolute, depending on what is passed to the
path
argument), and it should return either a dictionary or None. The dictionary should have names of arguments as keys and their respective setting as values.The following options can meaningfully be toggled by passing a formatter function:
depthlimit
,itemlimit
,beyond
,first
,sort
,sort_reverse
,sort_key
,include_folders
,regex
,mask
, as well as any seedir token keywords (extend
,space
,split
,final
,folderstart
,filestart
,folderend
,fileend
).Note that in version 0.3.0, formatter could only be used to update the style tokens. It can now be used to udpate those as well as the other arguments listed above.
If None is returned by formatter, the tokens will be set by
style
.Note that items exlcuded by the inclusion/exclusion arguments (or the
mask
) will not be seen by formatter. Similarly, any folder tree entries created by thebeyond
argument will not be seen by formatter. sticky_formatter
:bool
, optional- When True, updates to argumnts made by the
formatter
(see above) will be permanent. Thus, if arguments are updated when theformatter
is called on a folder, its children will (recursively) inherit those new arguments. slash
:str, option:
-
DeprecationWarning
: With addition offolderend
in v0.3.1,slash
is to be deprecated in a future version.Slash character to follow folders. If
'sep'
, usesos.sep
. The default is'/'
. **kwargs
:str
-
Specific tokens to use for creating the file tree diagram. The tokens use by each builtin style can be seen with
get_styleargs()
. Valid options areextend
(characters to show the extension of a directory while its children are traversed),space
(character to provide the correct indentation of an item when some of its parent / grandparent directories are completely traversed),split
(characters to show a folder or file within a directory, with more items following),final
(characters to show a folder or file within a directory, with no more items following),folderstart
(characters to prepend before any folder),filestart
(characters to preppend before any file),folderend
(characters to append after any folder), andfileend
(characters to append after any file). The following shows the default tokens for the'lines'
style:>>> import seedir as sd >>> sd.get_styleargs('lines') {'split': '├─', 'extend': '│ ', 'space': ' ', 'final': '└─', 'folderstart': '', 'filestart': '', 'folderend': '/', 'fileend': ''}
All default style tokens are 2 character strings, except for the file/folder start/end tokens. Style tokens from
**kwargs
are not affected by the indent parameter. Theuniform
,anystart
, andanyend
parameters can be used to affect multiple style tokens.
Returns
s (str)
orNone
- The tree diagram (as a string) or None if prinout = True, in which case the tree diagram is printed in the console.
