====================== ropevim, rope in vim ====================== 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: http://rope.sf.net/ New Features ============ * improved support of multibyte sources * implemented `extended complete` feature (disabled by default) * ropemode is not the part of distribution now Setting Up ========== First add ropevim folder to the ``PYTHONPATH`` (or install it using ``python setup.py install``). Then load ``ropevim.vim`` in vim. That can be done either by adding ``source path/to/ropevim.vim`` to your ``~/.vimrc`` or copying it to ``~/.vim/plugin/`` folder. If you don't want to install rope and ropevim you can add something like this to your ``~/.vimrc``:: let $PYTHONPATH .= ":/path/to/rope:/path/to/ropevim" source /path/to/ropevim.vim For using the repository version of rope, see ``docs/ropevim.txt``. 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 ``RopevimAutoImport`` 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 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. 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). ================ ============================ Key Command ================ ============================ C-x p o RopeOpenProject C-x p k RopeCloseProject C-x p f RopeFindFile C-x p 4 f RopeFindFileOtherWindow C-x p u RopeUndo C-x p r RopeRedo C-x p c RopeProjectConfig C-x p n [mpfd] RopeCreate(Module|Package|File|Directory) RopeWriteProject C-c r r RopeRename C-c r l RopeExtractVariable C-c r m RopeExtractMethod C-c r i RopeInline C-c r v RopeMove C-c r x RopeRestructure C-c r u RopeUseFunction C-c r f RopeIntroduceFactory C-c r s RopeChangeSignature C-c r 1 r RopeRenameCurrentModule C-c r 1 v RopeMoveCurrentModule C-c r 1 p RopeModuleToPackage C-c r o RopeOrganizeImports C-c r n [vfcmp] RopeGenerate(Variable|Function|Class|Module|Package) C-c r a / RopeCodeAssist C-c r a g RopeGotoDefinition C-c r a d RopeShowDoc C-c r a f RopeFindOccurrences C-c r a ?

You can define your own shortcuts like this:: :map <C-c>g :call RopeGotoDefinition() Ropevim itself comes with a few shortcuts. These shortcuts will be used only when ``ropevim_enable_shortcuts`` is set. ================ ============================ Key Command ================ ============================ M-/ RopeCodeAssist M-?
