In our case we want to change text within `()` as this is the condition in PHP. We

can achieve this by typing `ci(` within the braces.
|
||||
|
||||
Editing remote files
|
||||
--------------------
|
||||
|
||||
Vim implements different protocols and can open .gz or .zip files out of the box.
|
||||
Also scp:// and other protocols are support. This way one can edit remote files from
|
||||
local computer using his Vim.
|
||||
|
||||
To open a remote file type ``vim scp://daniel-siepmann.de/apps/staemme/allys.py``.
|
||||
|
||||
Or from within vim ``:e scp://daniel-siepmann.de/apps/staemme/allys.py``.
|
||||
|
||||
See ``:help scp``
|
||||
|
||||
Also you can open files under the cursor with system settings using ``gx``. To open a
|
||||
file under cursor with vim use ``gf``.
|
||||
|
||||
TASK: Edit the file
|
||||
https://tmp.daniel-siepmann.de/events/nca18/workshop-vim/example.html with vim.
|
||||
|
||||
Vimrc
|
||||
-----
|
||||
|
||||
Vim will load specific files during startup and in specific circumstances. The main
|
||||
file is ~/.vimrc on load. To persist settings, e.g. turned on line numbers, write
|
||||
them down into the file.
|
||||
|
||||
Like shell scripts, the file consists of Vim commands. E.g. turning line numbers on
|
||||
results in ``:set number``, so write ``set number`` to the file.
|
||||
|
||||
This way you can tune Vim to *YOUR* editor. You will not find two Vim users out there
|
||||
with the same setup. Vim is always *YOUR* editor.
|
||||
|
||||
Completion
|
||||
----------
|
||||
|
||||
Wait, an editor has completion? Yes, and Vim has a lot!
|
||||
|
||||
See: ``:help ins-completion`` It's a new mode! You can insert the mode inside the
|
||||
insert mode by typing ``CTRL+x`` followed by the completion mode.
|
||||
|
||||
TASK: Insert the word "hello" right here, using completion:
|
||||
|
||||
TASK: Insert the filename "lorem-ipsum2.php" right here, using completion:
|
||||
|
||||
TASK: Insert this chapter name right here, using completion:
|
||||
|
||||
The registers
|
||||
-------------
|
||||
|
||||
Vim comes with a lot of "clipboards". You have installed some fancy application for
|
||||
that? No need inside Vim. Clipboards within Vim are called registers. And there are a
|
||||
lot of them. Some are auto filled, some are up to you.
|
||||
|
||||
See ``:help registers`` You can copy stuff from within a file using ``"yyy`` or
|
||||
``"ayy`` where ``"a`` and ``"y`` is the register to copy to and ``yy`` is the motion,
|
||||
yank current line. As always, this can be combined with already known motions.
|
||||
|
||||
To paste from a register, use ``"yp`` where ``"y`` again is the register and ``p`` or
|
||||
``P`` is the paste after or before.
|
||||
|
||||
TASK: Yank this line and add it to "The dot".
|
||||
|
||||
TASK: Yank the first paragraph of "The registers" and paste if after this sentence.
|
||||
|
||||
The dot
|
||||
-------
|
||||
|
||||
Last time I didn't mention the "dot". Once you learn to make atomic operations within
|
||||
Vim, the dot becomes a huge productivity increase. He will repeat the last atomic
|
||||
operation, e.g. you insert a comma to the end of a line, you can repeat that.
|
||||
|
||||
TASK: Add a comma at the end of the first array entry within lorem-ipsum2.php and
|
||||
repeat the change for the two following lines.
|
||||
|
||||
Macros
|
||||
------
|
||||
|
||||
Some might already know macros from Microsoft Excel or other editors. Vim also comes
|
||||
with editors. A single macro is just a recorded set of keystrokes which can be
|
||||
re-played.
|
||||
|
||||
Each macro is saved into a register. Thus it can be saved, loaded and modified.
|
||||
|
||||
The change done within "The dot" section can be achieved using a macro.
|
||||
|
||||
To record a macro type ``qq`` where the first ``q`` starts the recording and the 2nd
|
||||
``q`` defined the register.
|
||||
|
||||
To replay a macro type ``@q`` where ``@`` starts the playback and ``q`` is the
|
||||
register. As most of the time you can prefix the playback with a count, e.g. ``2@q``
|
||||
will repeat macro ``q`` two times.
|
||||
|
||||
TASK: Repeat the task from "The dot" using a macro.
|
||||
|
||||
Settings Part 2
|
||||
---------------
|
||||
|
||||
We now should now all we need to work effectively with Vim. Still we didn't cover
|
||||
settings very well. We know how to show line numbers and how to store settings. But
|
||||
what kind of settings do we have, what can we achieve with settings?
|
||||
|
||||
Syntax highlighting
|
||||
^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
E.g. add the following to highlight hearts in red:
|
||||
|
||||
hi ERROR ctermfg=9
|
||||
match ERROR /♥/
|
||||
|
||||
TASK: Highlight the word TYPO3 in orange.
|
||||
Tip: Color code for orange is 214
|
||||
|
||||
See: ``:help hi`` ``:help match``
|
||||
|
||||
Autocommands
|
||||
^^^^^^^^^^^^
|
||||
|
||||
You know events from Symfony, or signals / slots from TYPO3? You will love
|
||||
autocommands in Vim.
|
||||
|
||||
See: ``:help autocommand``
|
||||
|
||||
Workflows
|
||||
---------
|
||||
|
||||
Now some workflows from my daily work within Vim.
|
||||
|
||||
Linting
|
||||
^^^^^^^
|
||||
|
||||
Executing tests
|
||||
^^^^^^^^^^^^^^^
|
||||
|
||||
Rendering docs
