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.

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 part of the distribution now

Installation

Using Minpac

filetype plugin on
call minpac#add('python-rope/ropevim')

$ pip install ropevim

If you're using Neovim, you will also need to install neovim python providers using pip install pynvim.

Using Packer

use({
  'python-rope/ropevim',
  ft = "python"
})

$ pip install ropevim

If you're using Neovim, you will also need to install neovim python providers using pip install pynvim.

Using Vim-Plug

filetype plugin on
Plug 'python-rope/ropevim'

$ pip install ropevim

If you're using Neovim, you will also need to install neovim python providers using pip install pynvim.

Using Vundle

filetype plugin on
Plugin 'python-rope/ropevim'

$ pip install ropevim

If you're using Neovim, you will also need to install neovim python providers using pip install pynvim.

Basic Installation

A simple way to download and install, which does just uses native packaging system (requires Vim 8):

$ mkdir -p ~/.vim/pack/plugins/start/
$ git clone https://github.com/python-rope/ropevim.git ~/.vim/pack/plugins/start/ropevim
$ pip install ropevim

Or on older Vim:

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

(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.)

If you're using Neovim, you will also need to install neovim python providers using pip install pynvim.

Installation with pathogen

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

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

(or even add this repo as a submodule to ~/.vim/bundle git repo if you have setup ~/.vim/bundle in this way and you should)

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

If you're using Neovim, you will also need to install neovim python providers using pip install pynvim.

Installation of repo version

For using the repository version of rope, see docs/ropevim.rst (or vim command :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 by default), you can search for files in your project. When you complete the minibuffer you'll see all files in the project; files are shown as their reversed paths. For instance projectroot/docs/todo.txt is shown like todo.txt<docs. 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 ropevim_vim_completion=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 ropevim_extended_complete=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 "= <default value>" 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:ropevim_autoimport_modules = ["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

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
 create_module: name=rope.contrib.generate.create_module
 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 <C-c>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
