*pymode-intro*

Python-mode is a vim plugin that allows you to use the pylint, rope, and pydoc

libraries in vim to provide features like python code bug checking,

refactoring, and some other useful things.

This plugin allows you to create python code in vim very easily. There is no

need to install the pylint or rope libraries on your system.

Python-mode contains all you need to develop python applications in Vim.

Features: *pymode-features*

- Support Python version 2.6+ and 3.2+

- Syntax highlighting

- Virtualenv support

- Run python code (``<leader>r``)

- Add/remove breakpoints (``<leader>b``)

- Improved Python indentation

- Python folding

- Python motions and operators (``]]``, ``3[[``, ``]]M``, ``vaC``, ``viM``,

``daC``, ``ciM``, ...)

- Code checking (pylint_, pyflakes_, pylama_, ...) that can be run

simultaneously (``:PymodeLint``)

- Autofix PEP8 errors (``:PymodeLintAuto``)

- Search in python documentation (``K``)

- Code refactoring <rope refactoring library> (rope_)

- Strong code completion (rope_)

- Go to definition (``<C-c>g`` for `:RopeGotoDefinition`)

- And more, more ...

*pymode-common*

This script provides the following options that can customizes the behavior of

PythonMode. These options should be set in your |vimrc|.

Below shows the default values.

Turn on the whole plugin *'g:pymode'*

Turn off plugin's warnings *'g:pymode_warnings'*

Add paths to `sys.path` *'g:pymode_paths'*

Value is list of path's strings.

Trim unused white spaces on save *'g:pymode_trim_whitespaces'*

By default pymode looks for current python version supported in your Vim.

You could choose prefer version, but value will be tested on loading.

*'g:pymode_python'*

Values are `python`, `python3`, `disable`. If value set to `disable` most

python-features of **pymode** will be disabled.

Set value to `python3` if you are working with python3 projects. You could use

*pymode-indent*

Pymode supports PEP8-compatible python indent.

Manually set breakpoint command (leave empty for automatic detection)

*pymode-lint*

Pymode supports `pylint`, `pep257`, `pep8`, `pyflakes`, `mccabe` code

checkers. You could run several similar checkers.

Pymode uses Pylama library for code checking. Many options like skip

files, errors and etc could be defined in `pylama.ini` file or modelines.

Check Pylama documentation for details.

Pylint options (ex. disable messages) may be defined in `$HOME/pylint.rc`

See pylint documentation.

Commands:

*:PymodeLint* -- Check code in current buffer

*:PymodeLintToggle* -- Toggle code checking

*:PymodeLintAuto* -- Fix PEP8 errors in current buffer automatically

Turn on code checking *'g:pymode_lint'*

Check code on every save (if file has been modified) *'g:pymode_lint_on_write'*

Check code when editing (on the fly) *'g:pymode_lint_on_fly'*

Show error message if cursor placed at the error line *'g:pymode_lint_message'*

Default code checkers (you could set several) *'g:pymode_lint_checkers'*

Values may be chosen from: `pylint`, `pep8`, `mccabe`, `pep257`, `pyflakes`.

Skip errors and warnings *'g:pymode_lint_ignore'*

E.g. "E501,W002", "E2,W" (Skip all Warnings and Errors that starts with E2) and etc

Select some error or warnings. *'g:pymode_lint_select'*

By example you disable all warnings starting from 'W', but want to see warning

'W0011' and warning 'W430'

Sort errors by relevance *'g:pymode_lint_sort'*

If not empty, errors will be sort by defined relevance

E.g. let g:pymode_lint_sort = ['E', 'C', 'I'] " Errors first 'E',

after them 'C' and ...

Auto open cwindow (quickfix) if any errors have been found

*'g:pymode_lint_cwindow'*

Place error |signs| *'g:pymode_signs'*

Definitions for |signs|

*pymode-lint-options*

Pymode has the ability to set code checkers options from pymode variables:

Set PEP8 options *'g:pymode_lint_options_pep8'*

See https://pep8.readthedocs.org/en/1.4.6/intro.html#configuration for more

info.

*pymode-rope*

Pymode supports Rope refactoring operations, code completion and code assists.

Commands:

|:PymodeRopeAutoImport| -- Resolve import for element under cursor

|:PymodeRopeModuleToPackage| -- Convert current module to package

|:PymodeRopeNewProject| -- Open new Rope project in current working directory

|:PymodeRopeRedo| -- Redo changes from last refactoring

|:PymodeRopeRegenerate| -- Regenerate the project cache

|:PymodeRopeRenameModule| -- Rename current module

|:PymodeRopeUndo| -- Undo changes from last refactoring

Turn on the rope script *'g:pymode_rope'*

*.ropeproject*

*:PymodeRopeNewProject* [<path>] -- Open new Rope project in the given path

*:PymodeRopeRegenerate* -- Regenerate the project cache

Rope uses a folder inside projects for holding project configuration and data.

Its default name is `.ropeproject`. It is recommended that you do not add the

.ropeproject folder to version control system.

Currently it is used for things such as:

* The config.py file in this folder contains project configuration. Have

a look at the default config.py file (which is created when it

does not exist) for more information.

* It can be used for saving project history, so that the next time you open the

project you can undo past changes.

* It can be used to save information about object inferences.

* It can be used to save a global name cache, which is used for auto-import.

By default, if `.ropeproject` is not found in the current directory, rope will

look recursively for it in parent folders.

Warning: If rope finds `.ropeproject` in a parent dir, it will use it with

all its child directories, which may slow scanning down (because of many,

possibly unrelated, files)

Enable searching for |.ropeproject| in parent directories

*'g:pymode_rope_lookup_project'*

You can also manually set the rope project directory. If not specified rope will

use the current directory.

*'g:pymode_rope_project_root'*

The location of the `.ropeproject` folder may also be overridden if you wish to

keep it outside of your project root. The rope library treats this folder as a

project resource, so the path will always be relative to your project root (a

leading '/' will be ignored). You may use `'..'` path segments to place the

folder outside of your project root.

*'g:pymode_rope_ropefolder'*

Show documentation for object under cursor. *'g:pymode_rope_show_doc_bind'*

Leave empty to disable the key binding.

Regenerate project cache on every save (if file has been modified)

*pymode-completion*

By default you can use <Ctrl-Space> for autocompletion. The first entry will

be automatically selected and you can press <Return> to insert the entry in

your code. <C-X><C-O> and <C-P>/<C-N> works too.

Autocompletion is also called by typing a period in |Insert| mode by default.

Turn on code completion support in the plugin *'g:pymode_rope_completion'*

Turn on autocompletion when typing a period

*'g:pymode_rope_complete_on_dot'*

Keymap for autocomplete *'g:pymode_rope_completion_bind'*

Extended autocompletion (rope could complete objects which have not been

imported) from project *'g:pymode_rope_autoimport'*

Load modules to autoimport by default *'g:pymode_rope_autoimport_modules'*

Offer to unresolved import object after completion.

*pymode-rope-findit*

By default when you press *<C-C>g* on any object in your code you will be moved

to definition.

Leave empty for disable key binding. *'g:pymode_rope_goto_definition_bind'*

Command for open window when definition has been found

Values are (`e`, `new`, `vnew`) *'g:pymode_rope_goto_definition_cmd'*

*pymode-rope-refactoring*

Pymode can rename everything: classes, functions, modules, packages, methods,

variables and keyword arguments.

Keymap for rename method/function/class/variables under cursor

*'g:pymode_rope_rename_bind'*

*:PymodeRopeRenameModule* -- Rename current module

Keymap for rename current module *'g:pymode_rope_rename_module_bind'*

*:PymodeRopeAutoImport* -- Resolve import for element under cursor

Organize imports sorts imports, too. It does that according to PEP8. Unused

imports will be dropped.

Keymap *'g:pymode_rope_organize_imports_bind'*

Insert import for current word under cursor *'g:pymode_rope_autoimport_bind'*

Should be enabled |'g:pymode_rope_autoimport'|

*'g:pymode_rope_module_to_package_bind'*

*:PymodeRopeModuleToPackage* -- convert current module to package

Keybinding:

*pymode-rope-extract*

Extract method/variable from selected lines.

*'g:pymode_rope_extract_method_bind'*

*'g:pymode_rope_extract_variable_bind'*

*pymode-rope-use*

It tries to find the places in which a function can be used and changes the

code to call it instead.

*pymode-rope-move*

It happens when you perform move refactoring on a method of a class. In this

refactoring, a method of a class is moved to the class of one of its

attributes. The old method will call the new method. If you want to change all

of the occurrences of the old method to use the new method you can inline it

afterwards.

*pymode-rope-undo*

*pymode-rope-redo*

Commands:

*:PymodeRopeUndo* -- Undo last changes in the project

*:PymodeRopeRedo* -- Redo last changes in the project

*pymode-syntax*

Turn on pymode syntax *'g:pymode_syntax'*

Slower syntax synchronization that is better at handling code blocks in

docstrings. Consider disabling this on slower hardware.

*'g:pymode_syntax_slow_sync'*

Enable all python highlights *'g:pymode_syntax_all'*

Highlight "print" as a function *'g:pymode_syntax_print_as_function'*

Highlight "async/await" keywords *'g:pymode_syntax_highlight_async_await'*

Highlight '=' operator *'g:pymode_syntax_highlight_equal_operator'*

Highlight '*' operator *'g:pymode_syntax_highlight_stars_operator'*

Highlight 'self' keyword *'g:pymode_syntax_highlight_self'*

Highlight indent's errors *'g:pymode_syntax_indent_errors'*

Highlight space's errors *'g:pymode_syntax_space_errors'*

Highlight string formatting *'g:pymode_syntax_string_formatting'*

*'g:pymode_syntax_string_format'*

*'g:pymode_syntax_string_templates'*

*'g:pymode_syntax_doctests'*

Highlight builtin objects (True, False, ...) *'g:pymode_syntax_builtin_objs'*

Highlight builtin types (str, list, ...) *'g:pymode_syntax_builtin_types'*

Highlight exceptions (TypeError, ValueError, ...)

*'g:pymode_syntax_highlight_exceptions'*

Highlight docstrings as pythonDocstring (otherwise as pythonString)

*'g:pymode_syntax_docstrings'*

*pymode-faq*

Python-mode doesn't work

Open any python file and run ":call pymode#troubleshooting#test()",

fix the warning or send me the output.

Rope completion is very slow *pymode-rope-slow*

Rope creates a project-level service directory in |.ropeproject|

If ``.ropeproject`` is not found in the current directory, rope will walk

upwards looking for a ``.ropeproject`` in every dir of the parent path. If

rope finds ``.ropeproject`` in a parent dir, it sets the project for all child

dirs and the scan may be slow for so many dirs and files.

Solutions:

- Delete `.ropeproject` from the parent dir to make rope create `.ropeproject`

in the current dir.

- Run ``:PymodeRopeNewProject`` to make rope create ``.ropeproject`` in the

current dir.

- Set |'g:pymode_rope_lookup_project'| to 0 for prevent searching in parent

dirs.

You may also set |'g:pymode_rope_project_root'| to manually specify the project

root path.

Pylint check is very slow

In some projects pylint may check slowly, because it also scans imported

modules if possible. Try using another code checker: see

|'g:pymode_lint_checkers'|.

You may set |exrc| and |secure| in your |vimrc| to auto-set custom settings

from `.vimrc` from your projects directories.
