ff
==
Easily search and process files.
If you need to search files by their contents, *or* search for their
contents, please look at `ack <https://github.com/petdance/ack2>`__ or
`pss <https://github.com/eliben/pss>`__. These are better suited for
this kind of task.
Current stable version
----------------------
1.0.5
Why ``ff`` and not ``find``?
----------------------------
Just because I find that most of my searches was:
::
find . -iname '*name*'
And it's easier to me to enter:
::
ff name
Also, my ``find`` have sometimes problems with non ascii names:
::
% find /tmp -name '*GÖS*'
%
And with ``ff``:
::
% ff '*GÖS*' /tmp
/tmp/eee_GÖS_från_förstår_pas
/tmp/eee_GÖS_från_pas_förstår_qq
/tmp/pas_GÖS_från_förstår
%
it just works! :)
Basic usage
-----------
::
ff passwd
Search for all files and directories in current directory and below,
which is match to pattern: ``*passwd*``.
::
ff -B passwd
Search for all files and directories in current directory and below,
which is match to pattern: ``*passwd``.
::
ff -E passwd
Search for all files and directories in current directory and below,
which is match to pattern: ``passwd*``.
::
ff -EB passwd
Advanced usage
--------------
::
ff -p pa -s /tmp --shell-exec -x '[ -f "{path}" ] && mkdir -p /tmp{dirname}; cp -r "{path}" "/tmp{path}"'
Find all files and directories in /tmp that match expression: ``*pa*``,
and copy them (with original directories hierarchy!) to /tmp.
So powerful!
Magic pattern
-------------
It's form of pattern known good for Perl or AWK lovers :)
If patterns is in general form:
::
mode/pattern/modifier
(decribed more in full usage below), then it is parsed and used in a
little other manner.
Instead of arguments ``--regexp`` or ``--fuzzy``, you can pass it in
``mode`` part of pattern. Next there is delimiter, which usually is
``/`` (backslash), but there can be more characters, described in Usage
section.
After that is a pattern, next delimiter again, and then modifiers
(again, modifiers are described in Usage section).
Some examples:
Search for all files and directories in current directory and below,
which is match to pattern: ``passwd``.
::
ff f/pwd/
Search for all files and directories in current directory and below,
which name contains letters 'p', 'w', 'd', with any other characters
between them.
::
ff g/^(chk)?passwd/
Search for all files and directories in current directory and below,
which name starts from 'chkpasswd' or 'passwd'.
Configuration file
------------------
``ff`` recognizes 2 configuration files: user-wide and project-wide.
Both can specify the same things and have identical syntax (ini files).
User-wide one is located in ``$HOME/.ff.rc``, and project-wide is
located in current directory (ie. projects root). Example file is
located at (github)[https://github.com/mysz/ff/blob/master/ff.rc].
Plugins
-------
Plugins are the way to easily extend capabilities of ``ff``. Currently
there is only support for plugins allowing to extend tests made on files
list. In future, there is plan to add support for plugins allowing to
make some actions on found files (currently is *built-in plugin*:
``--shell``), for example modifying, copying or anything else).
``ff`` search for plugins in user's home directory, but there is
posibility to tell him about the other.. By default, ``ff`` search for
plugins in:
- ``~/.ff/plugins``
And using switch ``--plugins-path`` you can tell ``ff`` about other
plugins location.
You can also pass argument to plugins. For example, in ``size`` plugin
(bundled with ``ff``), You must to tell the plugin what size of file You
expect:
::
`ff pas --test size:=5k`
Above example will find every file with *pas* part in its name, and its
size is *exactly* 5
`kibibytes <http://en.wikipedia.org/wiki/Binary_prefix#IEC_standard_prefixes>`__.
More about ``size`` plugin in `projects
wiki <https://github.com/mysz/ff/wiki/>`__.
Writing plugins
---------------
Plugins are written in `Python <http://python.org>`__, and are simple
Python modules with at least ``plugin_action`` callable specified.
Plugins are imported, and ``plugin_action`` must return ``True`` or
``False`` to tell ``ff`` that given found object meets expectations, and
should be returned.
``ff`` recognize and use only 3 objects in plugin:
- ``plugin_action`` - (REQUIRED) [callable] must return ``True`` od
``False``. Must recognize 3 arguments:
- ``name`` - name of plugin
- ``argument`` - argument passed by user
- ``path`` - absolute path to tested object
- ``PLUGIN_DESCR`` - (OPTIONAL) [string or callable] short descr of
plugin, printed when ``ff`` is called with switch
``--help-test-plugins``
- ``PLUGIN_HELP`` - (OPTIONAL) [string or callable] full help for
plugin, printed when ``ff`` is called with switch
``--help-test-plugins TEST_NAME``
Plugin file also must have special name, and be placed in directory
recognized by ``ff`` (see: [plugins][plugins]). Name of file is built
with three parts, connected with underscore: \* ``ffplugin`` - fixed
prefix \* ``test`` - type of plugin (currently only ``test`` plugins are
recignized) \* ``NAME`` - name of plugin
And as Python module, must and with ``.py`` extension :)
Plugin must validate input data (``argument``), and raise
``FFPluginError`` exception with approbiate message on any error. Plugin
shouldn't raise any other exceptions. There is one caveat with this:
``FFPluginError`` exception is declared *inside* ``ff``! When given
plugin is imported, it is *monkeypatched* and ``FFPluginError``
exception is injected into it.
There is an example plugin, which allow us to search for files in
specified size. Is in `project
repository <https://github.com/mysz/ff/tree/master/ff_plugins>`__ in
directory plugins. You can use it as a base for your own plugins :)
Installation
------------
``ff`` should work on any platform where `Python <http://python.org>`__
is available, it means Linux, Windows, MacOS X etc. There is no
dependencies, plain Python power :)
To install, you can use ``pip``:
::
pip install ff
Voila!

Easily search and process files.
positional arguments:
pattern pattern to search
source optional source (if missing, use current directory)
optional arguments:
-h, --help show this help message and exit
--print0, -0 split results by binary zero instead of new line
(useful to work with xargs)
--ignorecase, -i, --ignore-case
ignore case when match pattern to paths
--source source, -s source
optional, see: source above
--pattern PATTERN, -p PATTERN
optional, see: pattern above
--regexp, -g treat pattern as regular expression (uses Python
regexp engine)
--fuzzy, -f pattern defines only set and order of characters used
in filename
--depth DEPTH, -D DEPTH
how deep we should search (default: -1, means
infinite)
--path-search, -q search in full path, instead of bare name of item
--regex-multiline, -l
modify meta characters: "^" and "$" behaviour when
pattern is regular expression. See:
http://docs.python.org/2/library/re.html#re.MULTILINE
--regex-dotall, -d modify meta character: "." behaviour when pattern is
regular expression. See:
http://docs.python.org/2/library/re.html#re.DOTALL
--begin, -B match pattern to begin of item name (ignored in regexp
mode)
--end, -E match pattern to end of item name (ignored in regexp
mode)
--invert-match, -v, -r
find objects that do *not* match pattern
--mode MODE, -m MODE allow to choose to search for "files" only, "dirs", or
"all"
--exec COMMAND, -x COMMAND
execute some command on every found item. In command,
placeholders: {path}, {dirname}, {basename} are
replaced with correct value
--prefix add prefix "dr: " (directory) or "fl: " (file) to
every found item
--prefix-dirs PREFIX_DIRS
prefix for matched directories
--prefix-files PREFIX_FILES
prefix for matched files
--no-display don't display element (useful with --exec argument)
--no-colorize Colorize output
--verbose-exec show command before execute it
--interactive-exec ask before execute command on every item
--shell-exec execute command from --exec argument in shell (with
shell expansion etc)

--test TESTS, -t TESTS
additional tests, available by plugins (see
annotations below or --help-test-plugins)
--plugins-path PLUGINS_PATH
additional path where to search plugins (see
annotations below)
--version show program's version number and exit
--help-test-plugins [TEST_NAME[,TEST2_NAME]]
display help for installed test plugins
--show-plugins-paths Show recognized plugins paths and exit
Pattern, provided as positional argument (not with --pattern) can be provided
in special form (called: magic pattern). It allows to more "nerdish"
(or "perlish" :) ) way to control `ff` behavior.
The general pattern for magic pattern is:
mode/pattern/modifier
where:
mode - is one of 'p' (--pattern), 'g' - (--regexp) or 'f' (--fuzzy)
/ - is delimiter:
* one of: '/', '!', '@', '#', '%', '|', and then start and end
delimiter must be the same
* one of: '{', '[', '(', '<', and the end delimiter must be the
closing one (ex. '}' if start is '{')
pattern - any pattern, processed in a way specified with 'mode'
modifier - one of: 'i' (--ignore-case), 'm' (--regex-multiline),
's' (--regex-dotall), 'v' (not used currently), 'r' (--invert-match)
There is also ability to extend capabilities of `ff` by plugins. Plugins are
run with switch --test and then plugin name with optional plugin argument:
--test plugin_name:plugin_arg
There can be used more then one plugin at once.
