Project Description

Easily search and process files.

If you need to search files by their contents, or search for their contents, please look at ack or 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. More about size plugin in projects wiki.

Writing plugins

Plugins are written in Python, 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 in directory plugins. You can use it as a base for your own plugins :)

Installation

ff should work on any platform where Python 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!

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.
