Script Editors
|
|
==============
|
|
Third-party libraries are used to implement the game's Script Editor(s). There are
|
|
currently two options for the Script Editor:
|
|
|
|
* `Ace <https://ace.c9.io/>`_
|
|
* `CodeMirror <https://codemirror.net/>`_
|
|
|
|
You can select which of the two editors you want to use on the Script Editor page
|
|
('Create Script' on the main menu).
|
|
|
|
Ace was the game's original Script Editor, while CodeMirror was added later in
|
|
v0.43.0. The two editors share many of the same features, so there is not a significant
|
|
difference between the two. Currently, CodeMirror is slightly more modern,
|
|
more customizable, and has a few quality-of-life improvements compared to Ace.
|
|
|
|
Universal Key Bindings
|
|
----------------------
|
|
These keyboard shortcuts are available in both the Ace and CodeMirror editors, regardless
|
|
of what key binding option you are using:
|
|
|
|
============= ===========================================================================
|
|
Shortcut Action
|
|
============= ===========================================================================
|
|
Ctrl + b Save script and return to :ref:`terminal`
|
|
Ctrl + space Show Autocomplete Hints
|
|
============= ===========================================================================
|
|
|
|
.. _scripteditor_linter:
|
|
|
|
Linter
|
|
------
|
|
Both script editors contain a linter, which is a tool that analyzes your
|
|
code and flags anything it thinks might be an error. You can see
|
|
warnings and errors from the linter on the left-hand side of the script editor. There
|
|
will be an icon on whatever lines the linter thinks might be problematic. Hovering
|
|
over the icon will display information on what the issue is.
|
|
|
|
Note that **just because the linter shows an error/warning, this does NOT automatically mean that**
|
|
**your script is broken and will fail to run.** This is especially true if you are using
|
|
:ref:`netscriptjs`. The linter used by the script editors isn't necessarily perfect or
|
|
up-to-date. Furthermore, the linter does not affect anything when you actually run scripts.
|
|
|
|
Ace

|
|
The following documents what the different settings/options do for the Ace editor,
|
|
as well as the different key binding settings. Note that the
|
|
information for the key bindings may not be completely comprehensive. You'll
|
|
have to dig into the editor source code if you want to learn more.

Ace Key Bindings
|
|
~~~~~~~~~~~~~~~~
|
|
For Ace, the "Ace" Key Binding setting uses the default configuration. A list of these
|
|
`can be found here <https://github.com/ajaxorg/ace/wiki/Default-Keyboard-Shortcuts>`_.
|
|
|
|
Vim Key Bindings
|
|
~~~~~~~~~~~~~~~~
|
|
For Ace, the "Vim" Key Binding setting configures the editor to use
|
|
`Vim <https://en.wikipedia.org/wiki/Vim_(text_editor)>`_ key mappings. Note that while this tries
|
|
to emulate Vim features as faithfully as possible, it is not a complete Vim implementation.
|
|
|
|
Since I'm not familiar with Vim, I'll leave
|
|
`Ace's Vim Mode implementation here <https://github.com/ajaxorg/ace/blob/96088d0fc292daf0706b2d029cc03c3799be5974/lib/ace/keyboard/vim.js#L860>`_,
|
|
which I believe shows most of the implemented features.
|
|
|
|
Note that the following Vim Ex commands will properly save the script and/or quit the editor in game:
|
|
|
|
======= ==============================================
|
|
Command Effect
|
|
======= ==============================================
|
|
:w Save the script and return to :ref:`terminal`
|
|
:q Return to :ref:`terminal` **WITHOUT** saving
|
|
:x Save the script and return to :ref:`terminal`
|
|
:wq Save the script and return to :ref:`terminal`
|
|
======= ==============================================
|
|
|
|
Emacs Key Bindings
|
|
~~~~~~~~~~~~~~~~~~
|
|
For Ace, the "Emacs" Key Binding setting configures the editor to use
|
|
`Emacs <https://en.wikipedia.org/wiki/Emacs>`_ key mappings. Note that while this tries
|
|
to emulate the Emacs key mappings as faithfully as possible, it won't necessarily be a
|
|
complete implementation.
|
|
|
|
Since I'm not familiar with Emacs, I'll leave
|
|
`Ace's Emacs Mode implementation here <https://github.com/ajaxorg/ace/blob/96088d0fc292daf0706b2d029cc03c3799be5974/lib/ace/keyboard/emacs.js#L343>`_,
|
|
which I believe shows most of the implemented features.
|
|
|
|
CodeMirror
|
|
----------
|
|
The following documents what the different settings/options do for the CodeMirror editor,
|
|
as well as the shortcuts for the different key binding settings. Note that the
|
|
information for the key bindings may not be completely comprehensive. You'll
|
|
have to dig into the editor source code if you want to learn everything.
