The drag & drop behaviour of the text editor itself is kept as-is
(moving text blocks with the mouse etc., and also inserting file names
if dropped into the text area) because we don't want to re-implement all
of this ourselves.
However, we display a guidance text if a user drags files over the text
area telling them where to drop them to open.

The virtual stations are given as "VSTATIONx", not "POSITIONx"!
Moreover, more links to the online documentation have been added and the
syntax highlighting (in the PreviewWindow) now supports the coordinates
specifications (otherwise, coordinates provided with ";" were shown as
comments).

better "unsaved changes" warning.

It should finally be relatively clear to the user what happens when an
INI is opened, and closed seemingly without changing anything - namely
that the application may have inserted mandatory keys.

The fonts are now setup in the constructor. An unnecessary script has
been deleted.

-Move setting to 'preview' XML section because it exists from another setting now
-Remove obsolete documentation
-Clear status on TerminalView clear ("Process terminated" etc.)
-Remove useless _ from regex (it is checked by \w)
-Extend INIParser unit test with *::EXCLUDE example key
-Cosmetics
(Might want to clear settings with ./inishell -ce)

And a minor visual tweak to the line numbering

(it is licensed under BSD instead of GPL)

Now the line numbering can be considered ready to go

This addresses issue 827

Since we will never use images, etc in this editor...

Stealing code from MeteoIO, the copyright notice now shows the user name
and domain name (if available)

This fixes issue 829 with MeteoIO's "*::EXCLUDE" kind of keys. Moreover,
the new option for MeteoIO's deGrass filter has been included in the xml
file.

Allow : and _ in INI key names for preview syntax highlighting (not perfect but better). Set tooltip for Number panel when an expression is used.

Noteworthy: Removed fixed shortcut in doc because it is OS-dependent.

A few more icons have been added and a few colors tweaked for the dark
theme (sorry)

header' entry.

Some cleanup.

Unfortunately this seems to care about our syntax highlighting and I
can't find how to change the paragraph sign's color.

be given - this will flash the frame's border, enabling contextual help.

Add possibility to show the user guide with a specified tab opened. Use this to link to the Preview section from the preview menu.

actions

More preview menu fun: comment out all content, copy all content to comment (quick 'backup'), collect comments at bottom of file

Add preview editor menu entry to paste to new line (vim-style paste), cut whole line if selection is empty.

This is a quick keyboard combination to move keys around. Add shortcut
for 'quicksave'.

Restoring the selection is now more intelligent and cleaner. A little refactoring gets rid of empty undo stack entries.

the Preview editor.

Load the user's textual changes in the preview editor back into the parser before performing a transformation, thus taking them into consideration.

The chain should now be closed... getting there at least.

Trying not to use the term 'GUI' in the Preview menu... show the application's name instead (at the time of the preview click)

In an afterthought, start the undo history after the document was first inserted (no undoing back to blank)

The Preview integrates so nicely that we now do keep a local INIParser copy. By performing all transformations on that one, they now behave intuitively and can be applied one after another.
