ropevim, rope in vim

Overview

Ropevim is a vim mode that uses rope_ library to provide features like python refactorings and code-assists. You should install rope_ library before using ropevim.

.. _rope: https://github.com/python-rope/rope

New Features

• works only with python3 ATM (python2 is not supported anymore)
• improved support of multibyte sources
• implemented

  extended complete

  feature (disabled by default)
• ropemode is not the part of distribution now

Installation

Basic Installation

A simple way to download and install, which does not rely on any vim package managers, is:

.. code:: bash

$ sudo pip3 install rope ropemode ropevim $ wget -P ~/.vim/ https://raw.githubusercontent.com/python-rope/ropevim/master/ftplugin/pythonropevim.vim $ echo "source ~/.vim/pythonropevim.vim" >> ~/.vimrc

(rope, ropemode and ropevim are pure python libraries which do not need to talk to vim directly, they are installed by pip into the usual Python path. Only python_ropevim.vim needs to be seen by vim, and it handles loading the pure python modules.)

Installation with pathogen

If using pathogen.vim, and then simply copy and paste:

.. code:: bash

$ cd ~/.vim/bundle
$ git clone https://github.com/python-rope/ropevim.git

(or even add this repo as a submodule to

~/.vim/bundle

~/.vim/bundle

Once help tags have been generated, you can view the manual with

:help
ropevim.

Installation of repo version

For using the repository version of rope, see

docs/ropevim.rst

:help ropevim

Getting Started

Refactoring Dialog

Ropevim refactorings use a special kind of dialog. Depending on the refactoring, you'll be asked about the essential information a refactoring needs to know (like the new name in rename refactoring).

Next you'll see the base prompt of a refactoring dialog that shows something like "Choose what to do". By entering the name of a refactoring option you can set its value. After setting each option you'll be returned back to the base prompt. Finally, you can ask rope to perform, preview or cancel the refactoring.

See keybinding_ section and try the refactorings yourself.

Finding Files

By using

RopeFindFile

C-x p f

projectroot/docs/todo.txt

todo.txt.  This way you can find files faster in your
project.  
RopeFindFileOtherWindow
 (
C-x p 4 f
) opens the
file in the other window.

Code-Assist


RopeCodeAssist
 command (
M-/
) will let you select from a list
of completions.  
RopeLuckyAssist
 command (
M-?
) does not ask
anything; instead, it inserts the first proposal.

You can tell ropevim to use vim's complete function in insert mode;
Add::

let ropevimvimcompletion=1

to your 
~/.vimrc
 file.

Note that when this variable is set, autoimport completions no longer
work since they need to insert an import to the top of the module, too.

By default autocomplete feature will use plain list of proposed completion
items. You can enable showing extended information about completion
proposals by setting ::

let ropevimextendedcomplete=1

Completion menu list will show the proposed name itself, one letter which
shows where this proposal came from (it can be "L" for locals, "G" for
globals, "B" for builtins, or empty string if such scope definition is not
applicable), a short object type description (such as "func", "param",
"meth" and so forth) and a first line of proposed object's docstring (if it
has one). For function's keyword parameters the last field shows "*" symbol
if this param is required or "= " if it is not.

Note that you'll need rope r1558:0d76aa9d0614 or later and ropemode
r35:bd77ca42b04d or later for extended complete feature to work.

Enabling Autoimport

Rope can propose and automatically import global names in other
modules.  Rope maintains a cache of global names for each project.  It
updates the cache only when modules are changed; if you want to cache
all your modules at once, use 
RopeGenerateAutoimportCache
.  It
will cache all of the modules inside the project plus those whose
names are listed in 
ropevim_autoimport_modules
 list::

# add the name of modules you want to autoimport
  let g:ropevimautoimportmodules = ["os", "shutil"]

Now if you are in a buffer that contains::

rmtree

and you execute 
RopeAutoImport
 you'll end up with::

from shutil import rmtree
  rmtree

Also 
RopeCodeAssist
 and 
RopeLuckyAssist
 propose auto-imported
names by using 
name : module
 style.  Selecting them will import
the module automatically.

Filtering Resources

Some refactorings, restructuring and find occurrences take an option
called resources.  This option can be used to limit the resources on
which a refactoring should be applied.

It uses a simple format: each line starts with either '+' or '-'.
Each '+' means include the file (or its children if it's a folder)
that comes after it.  '-' has the same meaning for exclusion.  So
using::

+rope
  +ropetest
  -rope/contrib

means include all python files inside 
rope
 and 
ropetest
folders and their subfolder, but those that are in 
rope/contrib
.
Or::

-ropetest
  -setup.py

means include all python files inside the project but 
setup.py
 and
those under 
ropetest
 folder.

Finding Occurrences

The find occurrences command (
C-c f
 by default) can be used to
find the occurrences of a python name.  If 
unsure
 option is
yes
, it will also show unsure occurrences; unsure occurrences are
indicated with a 
?
 mark in the end.  Note that ropevim uses the
quickfix feature of vim for marking occurrence locations.

Dialog 
batchset
 Command

When you use ropevim dialogs there is a command called 
batchset
.
It can set many options at the same time.  After selecting this
command from dialog base prompt, you are asked to enter a string.


batchset
 strings can set the value of configs in two ways.  The
single line form is like this::

name1 value1
  name2 value2

That is the name of config is followed its value.  For multi-line
values you can use::

name1
   line1
   line2

name2
   line3

Each line of the definition should start with a space or a tab.  Note
that blank lines before the name of config definitions are ignored.


batchset
 command is useful when performing refactorings with long
configs, like restructurings::

pattern ${pycore}.create_module(${project}.root, ${name})

goal generate.create_module(${project}, ${name})

imports
   from rope.contrib import generate

args
   pycore: type=rope.base.pycore.PyCore
   project: type=rope.base.project.Project

.. ignore the two-space indents

This is a valid 
batchset
 string for restructurings.

Just for the sake of completeness, the reverse of the above
restructuring can be::

pattern ${create_module}(${project}, ${name})

goal ${project}.pycore.create_module(${project}.root, ${name})

args
   createmodule: name=rope.contrib.generate.createmodule
   project: type=rope.base.project.Project

Variables



ropevim_codeassist_maxfixes
: The maximum number of syntax errors
to fix for code assists.  The default value is 
1
.

ropevim_local_prefix
: The prefix for ropevim refactorings.
Defaults to 
C-c r
.

ropevim_global_prefix
: The prefix for ropevim project commands
Defaults to 
C-x p
.

ropevim_enable_shortcuts
: Shows whether to bind ropevim
shortcuts keys.  Defaults to 
1
.


ropevim_guess_project
: If non-zero, ropevim tries to guess and
open the project that contains the file on which a ropevim command
is performed when no project is already open.


ropevim_enable_autoimport
: Shows whether to enable autoimport.


ropevim_autoimport_modules
: The name of modules whose global
names should be cached.  
RopeGenerateAutoimportCache
 reads this
list and fills its cache.


ropevim_autoimport_underlineds
: If set, autoimport will cache
names starting with underlines, too.


ropevim_goto_def_newwin
: If set, ropevim will open a new buffer
for "go to definition" result if the definition found is located
in another file. By default the file is open in the same buffer.


g:ropevim_open_files_in_tabs
: If non-zero, ropevim will open files
in tabs. This is disabled by default, and it is now deprecated in
favor of 
g:ropevim_goto_def_newwin
 set to 
"tabnew"
.


Keybinding

Uses almost the same keybinding as ropemacs.  Note that global
commands have a 
C-x p
 prefix and local commands have a 
C-c r
prefix.  You can change that (see variables_ section).

Shortcuts                                                                

Some commands are used very frequently; specially the commands in

code-assist group.  You can define your own shortcuts like this::        

:noremap g :call RopeGotoDefinition()                                

Ropevim itself comes with a few shortcuts.  These shortcuts will be

used only when 
ropevim_enable_shortcuts
 is set.

Support for Omni completion

You can enable using Rope as providing for Omni completion by setting
omnifunc variable to 
RopeCompleteFunc
. E.g., by putting something
like this in your 
~/.vimrc
::
autocmd FileType python setlocal omnifunc=RopeCompleteFunc
