The vim module implements two methods, three constants, and one error object. You need to import the vim module before using it: :python import vim overview :py print "Hello" displays a message :py mmand(cmd) execute an Ex command :py w vim. Windowsn gets window "n" :py cw rrent. Window gets the current window :py b ffersn gets buffer "n" :py cb ffer gets the current buffer :py. Height lines sets the window height :py rsor (row, col) sets the window cursor position :py pos rsor gets a tuple (row, col) :py name me gets the buffer file name :py line bn gets a line from the buffer :py lines bn:m gets. Examples: :py mmand set tw72 :py mmand s/aaa/bbb/g The following definition executes Normal mode commands: def normal(str mmand normal "str) Note the use of single"s to delimit a string containing double"s normal a2dd"ap * E659 * The " :python " command.

Also make sure the "class" line and "EOF" do not have any indent. pyfile * * :pyf * :rangepyfile file Execute the python script in file. The whole argument writing is used as a single file name. Not in vi both of these commands do essentially the same thing - they execute a piece of Python code, with the "current range" python-range set to the given line range. In the case of :python, the code to execute is in the command-line. In the case of :pyfile, the code to execute is the contents of the given file. Python commands cannot be used in the sandbox. To pass arguments you need to set gv explicitly. Example: :python import sys :python gv "foo "bar" :pyfile here are some examples * python-examples * :python from vim import * :python from string import upper :python ne upper(ne) :python print "Hello" :python str ffer42 (Note that changes - like the imports - persist from one. The vim module * python-vim * Python code gets all of its access to vim (with one exception - see python-output below) via the "vim" module.

If endmarker is omitted from after the " a dot '. ' must be used after script, like for the :append and :insert commands. This form of the :python command is mainly useful for including python code in Vim scripts.

python write eof

Python, eoferror: eof when reading a line, stack overflow

The vim module python-vim. Buffer objects python-buffer. Range objects python-range. Window objects python-window. Dynamic loading python-dynamic. Python 3 python3, vi does not have any of these commands. The, python.x interface is available only when Vim was compiled with the python feature. The, python 3 interface is available only when Vim was compiled with the python3 feature.

Write( data ) Write some data bytes to the transport: see writeTransport. Writelines( data ) Write a list (or any iterable) of data bytes to the transport: see writeTransport. Write_eof Close the write end of the transport after flushing buffered data: see writeTransport. StreamReaderProtocol class reamReaderProtocol( stream_reader, client_connected_cbNone, loopNone ) Trivial helper class to adapt between Protocol and StreamReader. Stream_reader is a streamReader instance, client_connected_cb is an optional function called with (stream_reader, stream_writer) when a connection is made, loop is the event loop instance to use. (This is a helper class instead of making StreamReader itself a protocol subclass, because the StreamReader has other potential uses, and to prevent the user of the StreamReader from accidentally calling inappropriate methods of the protocol.).

IncompletereadError exception completereadError Incomplete read error, subclass of eoferror. Expected Total number of expected bytes ( int ). Partial read bytes string before the end of stream was reached ( bytes ). LimitOverrunError exception mitOverrunError reached the buffer limit while looking for a separator. Consumed Total number of to be consumed bytes. Tcp echo client using streams tcp echo client using the asyncio. Open_connection function: import asyncio async def tcp_echo_client(message, loop reader, writer await asyncio. Open_connection 8888, looploop) print Send: r' message) writer.

Should be called after close to wait until the underlying connection (and the associated transport/protocol pair) is closed. Coroutine drain let the write buffer of the underlying transport a chance to be flushed. The intended use is to write:. Drain When the size of the transport buffer reaches the high-water limit (the protocol is paused block until the size of the buffer is drained down to the low-water limit and the protocol is resumed. When there is nothing to wait for, the yield-from continues immediately. Yielding from drain gives the opportunity for the loop to schedule the write operation and flush the buffer. It should especially be used when a possibly large amount of data is written wood to the transport, and the coroutine does not yield-from between calls to write. Return optional transport information: see t_extra_info.

python write eof

This exposes write, daily writelines, can_write_eof, write_eof, get_extra_info and close. It adds drain which returns an optional Future on which you can wait for flow control. It also adds a transport attribute which references the Transport directly. This class is not thread safe. Can_write_eof return True if the transport supports write_eof, false if not. Close close the transport: see ose. Is_closing return True if the writer is closing or is closed. New in version.7. Coroutine wait_closed wait until the writer is closed.

be returned, not counting the separator. If an eof occurs and the complete separator is still not found, an IncompletereadError exception will be raised, and the internal buffer will be reset. The rtial attribute may contain the separator partially. If the data cannot be read because of over limit, a limitOverrunError exception will be raised, and the data will be left in the internal buffer, so it can be read again. New in version.5.2. At_eof return True if the buffer is empty and feed_eof was called. StreamWriter class reamWriter( transport, protocol, reader, loop ) Wraps a transport.

Read up to n bytes. If n is not provided, or set to -1, read until eof and return all read bytes. If the eof was received and the internal buffer is empty, return an empty bytes object. This method is a coroutine. Read one line, where line is a sequence of bytes ending with. If eof is received, and n was not found, the method will return the partial read bytes. Coroutine readexactly( n ) read exactly n bytes. Raise an IncompletereadError if the end of the stream is reached before n can be read, the rtial attribute of the exception contains the partial read bytes. Coroutine readuntil( separatorb'n' ) read data from the stream until separator is found.

Streams (coroutine based api) — python.7.0 documentation. StreamReader class reamReader( limitNone, loopNone this class is not thread safe. Exception get the exception. Feed_eof acknowledge the eof. Feed_data( data feed data bytes in the internal buffer. Any operations waiting for add the data will be resumed. Set_exception( exc set the exception. Set_transport( transport set the transport. Coroutine read( n-1 ).
