iterfzf.iterfzf(iterable, *, **options)
Consumes the given iterable
of strings, and displays them using fzf
.
If a user chooses something it immediately returns the chosen things.
The following is the full list of parameters. Pass them as
keyword arguments except for iterable
which comes first:
iterable
(required)
The only required parameter. Every element which this iterable
yields
is displayed immediately after each one is produced. In other words,
the passed iterable
is lazily consumed.
It can be an iterable of byte strings (e.g. [b'foo', b'bar']
) or of
Unicode strings (e.g. [u'foo', u'bar']
), but must not be
mixed (e.g. [u'foo', b'bar']
). If they are byte strings the function
returns bytes. If they are Unicode strings it returns Unicode strings.
See also the encoding
parameter.
sort
Sorts the result if True
. False
by default.
multi
True
to let the user to choose more than one. A user can select
items with tab/shift-tab. If multi=True
the function returns a list of
strings rather than a string.
False
to make a user possible to choose only one. If multi=False
it returns a string rather than a list.
For both modes, the function returns None
if nothing is matched or
a user cancelled.
False
by default.
Corresponds to -m
/--multi
option.
bind
The key/event bindings to pass to fzf
.
Dictionary of the form {KEY: ACTION} or {EVENT: ACTION}.
Corresponds to --bind=KEYBINDS
option.
print_query
If True
the return type is a tuple where the first element is the query
the user actually typed, and the second element is the selected output as
described above and depending on the state of multi
.
False
by default.
Corresponds to --print-query
option.
New in version 0.3.0.
encoding
The text encoding name (e.g. 'utf-8'
, 'ascii'
) to be used for
encoding iterable
values and decoding return values. It's ignored
when the iterable
values are byte strings.
The Python's default encoding (i.e. sys.getdefaultencoding()
) is used
by default.
extended
True
for extended-search mode. False
to turn it off.
True
by default.
True
corresponds to -x
/--extended
option, and
False
corresponds to +x
/--no-extended
option.
exact
False
for fuzzy matching, and True
for exact matching.
False
by default.
Corresponds to -e
/--exact
option.
case_sensitive
True
for case sensitivity, and False
for case insensitivity.
None
, the default, for smart-case match.
True
corresponds to +i
option and False
corresponds to
-i
option.
query
The query string to be filled at first. (It can be removed by a user.)
Empty string by default.
Corresponds to -q
/--query
option.
prompt
The prompt sequence. ' >'
by default.
Corresponds to --prompt
option.
preview
The preview command to execute. None
by default.
Corresponds to --preview
option.
mouse
False
to disable mouse. True
by default.
Corresponds to --no-mouse

False

Versioning scheme
Note that ``iterfzf`` does *not* follow `Semantic Versioning`_. The version
consists of its own major and minor number followed by the version of bundled
``fzf``. For example, 1.2.3.4.5 means that ``iterfzf``'s own major version
is 1, and its own minor version is 2, plus the version of ``fzf`` it bundles
is 3.4.5.
