SciTE-GUI: GUI Extensions for SciTE Lua

[SteveD]

SciTE-GUI is a binary extension for SciTE Lua written in C++ which
gives Lua scripts the ability to interact with the user with GUI
elements like lists, file and colour dialogs, message boxes, prompt
for string, etc. It also provides a few useful utility functions like
gui.run(), which can launch an arbitrary program or document without
blocking, etc. There's an example showing a context-sensitive floating
toolbar, as previously promised.

It's possible to attach these GUI elements to the main frame of SciTE
itself:

http://mysite.mweb.co.za/residents/sdonovan/SciTE/scite.png

(Note well that this required _no changes_ to SciTE itself; it is all
done with window subclassing voodoo.)

Here is the documentation, source and binary dll (MSVC6):

http://mysite.mweb.co.za/residents/sdonovan/SciTE/gui_ext.zip

Put gui.dll next to your SciTE.exe and call require("gui") in your
scripts; things should then just work.

Most of the C++ is quite old and sloppy (it is based on a library I
wrote when I was young and foolish, plus VC6 is very tolerant) but I
hope to have a mingw buildable version out soon.

This sounds very interesting.
Thank you Steve.
We'll wait for MinGW version.

This is just the GUI extension I have been waiting for so long!! Thank you
Steve! I have already played around with it for a few hours. One question
though:
Is it possible to not print any statements in console output when switching
between tabs? I usually minimize my console output window, it's kinda
annoying every time I switch tabs then it pops up.

Thanks,
Nessus

Fortunately, this is an easy one! In the gui-test.lua example (which
I assume is the one you're using), there is the following code:

t:on_select(function(idx)
print('tab',idx)
end)

Just comment out the print statement! There's no actual printing going
on within the DLL itself.

This is really great :)
However after adding require("gui") to startup lua something goes
wrong with codepage - I cant use anymore national letters. My
settings:
code.page=1250
character.set=238

[instanton]

While trying files.lua I encountered some minor problem: double clicking on while spaces in the panel, SciTE crashes. Looking into the lua code, I got a solution: it is better not to check if file/dir/pos is not nil, but check if idx is not -1 instead. This way no crash will occur while double clicking on while spaces.

 

Many thanks to Steve for this execlent GUI component.

I'm playing with SciTE-GUI and hope to be able to input some words into the editor pane by double clicking on a list shown in a GUI window. For example, with the following code,

 

##-------Code begin-----------

w2 = gui.window "MyList"
w2:size(200,369)
w2:position(1025,368)
wls = gui.list()
wls:add_item('stuff')
wls:add_item('nonsense')
w2:client(wls)
w2:show()

 

wls:on_double_click(function(idx)

 if not (idx == -1) then

  local item = wls:get_item_data(idx)
  editor:append(item)
 end
end)

 

##---------Code end-------------

 

I expact that by double clicking on the item "stuff" shown in the window "MyList", the word "stuff" will be inserted to the editor pane. However instead of the expected behavior, I got a SciTE crash. Changing the line editor:append(item) into print(item), I got "nil" printed in the output pane. Can anyone please tell what I am doing wrong? (Steve, please?)

 

Thanks.

If you had said wls:get_item_text(idx), things would work as you
expected...

item data is any old Lua value which can be associated with an item.
To add such data, use 2nd arg of add_item:

wls:add_item("stuff","STUFF")
wls:add_item("nonsense","NONSENSE")

BTW, guys, the thing I MUST sort out is this instability. Usual bad
habit of not checking that input values are sane ;)

Hi, Steve,

 

Many thanks.

 

Now I have several more questions in configuring SciTE-GUI.

 

1) I wish to define more than one panels, is this pissible at all? If not, I would prefer to write several Lua functions, each defines a panel, and call one of them at a time. The question is then: is there an operation control which closes the currently openning panel?

 

2) I like the panel organization defined in files.lua very much. I would like to make similar horizontal separations to a tabbed gui window by columns (i.e. like Directories, Bookmarks and Files columns), but it seems that when tab changes only the last column can change with the tab, while the first columns appears to be fixed regardless of the tab switching. Is there a way to separate a tabbed window horizontally and let each part switch with the tab?

You can control the visibility of forms with the show()/hide()
methods. But you are talking about the embedded panels. Currently,
there's just one 'slot' for a panel, on the right; we could make all
positions available for panels.

It can be done! The trick is to put the controls into a panel object,
then put this panel into a tab, and finally put the tab into another
panel, which is attached to the side. For instance, here is the GUI
setup for files.lua, generalized to add a tab:

local w = gui.panel(100)

local ls = gui.list(true)
local dirs = gui.list(true)
local bookmarks = gui.list(true)

ls:add_column("Files",100);
dirs:add_column("Directories",100)
bookmarks:add_column("Bookmarks",100)
w:add(dirs,"top",150)

w:add(bookmarks,"top",150)
w:client(ls)
w:show()

local panel = gui.panel(100)
local extras = gui.list()
extras:add_item 'hello'
extras:add_item 'dolly'
local tabs = gui.tabbar(panel)
tabs:add_tab("files",w)
tabs:add_tab("extras",extras)
panel:client(w)
gui.set_panel(panel,"right")

The window hierarchy now looks like this:

panel
-- tabs
-- files
-- ls
-- dirs
-- bookmarks
-- extras

Note that when using a tab you have to explicitly show the active tab
'panel:client(w)' afterwards. I mention this because I forgot to do it
at first and was puzzled at the grey empty tab ;)

This fresh version brings two things to the party:
- it can be built using MinGW - there is a makefile. This mostly
involved bringing some old C++ code into the 21st century.
- it has a lot more API checks, so it is less likely to crash SciTE.

I am interested in what new features people have strong feelings
about. I'd like to add a tree view, since I've done the hard part of
wrapping it in C++. Also, people may like to attach panels to any
side (top,left,right,bottom) of the editor pane; may not be my cup of
tea, but if there's demand I'll generalize the sizing code.

I am going to come out with a new version of SciTE-Debug which uses
this extension to show watches, inspect variables, etc.

It would be cool to have a version which implemented the same API for
GTK versions. The best candidate so far has been lua-gtk, but it is a
real bitch to compile; I may go for a direct port.

I still don't understand why this DLL would mess with the code page
settings, but I will continue to try track this one down.

Hi Steve, is this not the same version as before? I tried the first
release but it didn't work with SciTE 1.74. Is this version of SciTE to old?

Hi, Steve,
As someone has already pointed out, the link above is the same old version. I saw no changes to either the source code or the comopiled binary.

That sounds teriffic.

I'll vote for the tree view panel and a tabbed view in place of the output pane. Meanwhile, I strongly suggest to implement a docking property for the floating toolbar, i.e. if placing the floating toolbar on top of the built-in toolbar or next to it, it should appear as a second toolbar attached to the main window. Moreover, it would become more useful if one can use command IDs rather than the lua function names or built-in function names while configuring the toolbar (command IDs can be asigned to any user defined tools, for instance, not only restricted to the ones defined via lua script).

Sorry about that; case-sensitive file systems bite again!

http://mysite.mweb.co.za/residents/sdonovan/scite/gui_ext.zip

The last link was definitely the old version.

I've been testing with 1.75. I think that was the point where the Lua
symbols got exported, which is necessary for this DLL to work.

Works perfectly. Thank you very much Steve.

I have another feature request: is it possible to enable styling for the panel(s)? I ask this because many SciTE users use dark scheme settings but the default panel background is white which looks inconsistent with the overall colour scheme.

This seems like a good feature, since white panels are very harsh if
you like working in the dark ;)

I shall expose methods to set foreground and background colours.

I put "require("gui")" in my startup script , no other code added .
When I restart SciTE , it crashed .
Then I add a line "gui.message("Hello World","message")" , when I
start the application
again , the message dialog appeared , but after that , SciTE crashed
again .

[SteveD]

What version of SciTE and what version of Windows?

This is exactly what happens on my system, and with both versions of
gui.dll.
Same setup; i.e. SciTE 1.76, Windows XP professional SP2, no Tigermilk
or other emulators/virtual machines installed.

That is worrying. What I shall do is release a version which doesn't
do the subclassing, just to see if that's the problem. You won't be
able to attach panels to the side, but it will be a useful data point
in discovering what the real problem is.

steve d.

[SteveD]

http://mysite.mweb.co.za/residents/sdonovan/scite/gui_ext.zip

The new thing this brings to the party is the ability to change the
colours of the list and text views.

ls:set_list_colour("#FFFFFF","#000000") -- foreground, background!
txt:set_memo_colour("#FFFFFF","#000000")

Note a limitation of list custom draw: the selection colours can't be
changed, which is a bit of a bummer.

This zip also contains ngui.dll, which doesn't attempt to subclass
Scite (just say require 'ngui' instead of require 'gui'); I've put
this in because I'm curious to see if people still get SciTE crashes
with this one.

In any case, gui.dll is now more careful when it subclasses, and may
be able to detect when it can't - it will then pop up an error message
but shouldn't bring SciTE down.

The dodgy part of the subclassing is that it assumes that the
currently active window is actually the SciTE main frame window. From
there it works from the expected structure of SciTE's windows; the
first child is the content pane, the first child of that is the main
editor Scintilla, etc. This does strike me as being rather
trusting ;) In fact what I need to do is to enumerate all SciTE top-
level windows (by class) and find the one that belongs to the current
iinstance.

Anyway, give it a bash and tell me what the errors are now...

steve d.

[SteveD]

A second thought: the thing about 'ngui.dll' is that it cannot put the
panel down the side, but you can create separate windows. It's really
there until we have this subclassing problem sorted - if it has to do
with subclassing!

I don't have the crash problem, and I don't quite understand the subclassing. But I suggest that the side panels should be attached to the SciTE main frame, not just to the editor pane, i.e. if the panel appears at the right, its height should be roughly the sum of that of the editor pane and of the output pane.

One further feature request: I hope that when double clicking on the panel seperator, the corresponding content could be maxmized (i.e. takes up most of the panel space) while the contents under other seperators should be minimized, leaving only the seperator bar visible. If I didn't describe the requested effect well enough, please see the side panel of TeXMaker.

A last question is: is it possible to change the fonts used for tabbars, horizontal seperators etc?

Bests,

I'll look at that possibility.

The sidepanels of Visual Studio work something like that - I like this
idea. Would we also need to have 'restored' panes as well? If
there's just minimized/maximized, it's basically a kind of vertical
tab page.

> A last question is: is it possible to change the fonts used for tabbars, horizontal seperators etc?

The custom draw framework allows for this - I used it just to change
the drawing colours, but you can actually substitute your own font
using this technique. So this is very doable.

Could you please give am example on this? I ask this feature because the font used for tabbar is different from the one on menubar and other places. I attach a schreenshot of my configuration.

ngui.dll works for me - no more crashes :-)
I haven't played around with it much yet, but it does run gui-test.lua.

[SteveD]

Cool - so it's bad subclassing - that should be a solveable problem!

[SteveD]

I see your problem - I have noticed the different font, although it
was just slightly irritating. But if you're getting a completely
different character set, then we have an issue ;)

I will have to add a method to change the font, and make some changes
to the custom draw handler. You're welcome to mess with the source, if
you feel you can handle a little C++.

Unfortunately, this is going to have to wait, because I have to be out
of the country for 2 weeks, conferences and things, and will be away
from my beloved computer. This is probably a good idea for my mental
health anyway.

works with ctrl+f2 without problems, but sciteru has a feature to set
Bookmarks by clicking the margin. this seems not to trigger the message
to the script-handler => the bookmark is set, but not added to the list.

here the corresponding code-snippets:

scitebase.cxx:4889:
case SCN_MARGINCLICK: {
if (extender)
handled = extender->OnMarginClick();
if (!handled) {
//!-start-[SetBookmark]
if (notification->margin == 1) {
int lineClick = int(SendEditor(SCI_LINEFROMPOSITION,
notification->position));
BookmarkToggle(lineClick);
}

scitebase.cxx:2041:
void SciTEBase::BookmarkToggle(int lineno) {
if (lineno == -1)
lineno = GetCurrentLineNumber();
if (BookmarkPresent(lineno)) {
BookmarkDelete(lineno);
} else {
BookmarkAdd(lineno);
}
}

scitebase.cxx:2020:
void SciTEBase::BookmarkAdd(int lineno) {
if (lineno == -1)
lineno = GetCurrentLineNumber();
if (!BookmarkPresent(lineno))
SendEditor(SCI_MARKERADD, lineno, markerBookmark);
}

has anybody an idea to fix this?

This interesting decision.
Many magnificent ideas could will be carried out if gui-ext worked well.
It is excellent library but too many bugs.
I cannot work with her till that time while the basic bugs will not be corrected.
The main thing is that in SciTE it becomes impossible to write in Russian
and that panels are displayed very much not stably.

You are completely right.
At set of a bookmark with click on the margin do not trigger message IDM_BOOKMARK_TOGGLE.
Your decision of this problem will be considered.

which bugs do you mean? the actual version seems to work stable for me
(if you do not have bugs in the scipt).

in the screen you can see, that the string is cut off after specific
length (... appended), can this be changed to show the full string?

can anybody help me to change the pas-expression so that only [p]
instead of procedure and [f] instead of function is shown?
here my current regexp:

['pas']="\n([pPff][rRuU][oOnN][cC][eEtT][dDiI][uUoO][rRnN].-%b().-)\n",

this lists like i the screenshot shown.

This may be solved by calling the string.gsub method once again before the line

ls:add_item(findString,{props['FilePath'],line})

i want to try tabbar, but i can't get it working...here my code:

local w = gui.panel(200)
local ls = gui.list()
local bookmarks = gui.list()

gui.set_panel(w,"right")
ls:size(100,100)

-- w:add(bookmarks,"top",100)
-- w:add(ls,"top",300)

-- tabs
t = gui.tabbar(w)
t:add_tab("column list",ls)
t:add_tab("bookmarks",bookmarks)
w:client(t)

-- end tabs

w:show()

the previous version with the 2 w:add-lines and without tabbar-code
works fine.
with tabbar, i see the tabbar, not the client of the first tab (ls), the
client-area is grey. if i switch the the tab to the second, the tabbar
dissapears and i see only client of second tab (bookmarks) and can't
switch back.
maybe i don't exactly understod the tabbar-code in the example but the
documentation says not much :)

btw. the bookmark-code also not handling linecount-change because the
line-numbers are added to the list. isn't there a way to access the
bookmarks-list from scite?

regards Frank

[Frank Wunderlich]

i've tried that that way, but don't know how to walk through my
replace-table to call gsub with key and value:

local replaceRegExp = {
['pas']={
['[pP][rR][oO][cC][eE][dD][uU][rR][eE]']="[p]",
['[fF][uU][nN][cC][tT][iI][oO][nN]']="[f]"
}
}

local replacePattern = replaceRegExp [props["FileExt"]]

if replacePattern~=nil then
for s,r in replacePattern do
string.gsub (line, s, r)
end
end

in the lua-documentation i also found foreach and foreahi, but it seems
that these 2 functions are not able to get the key-name.
any ideas?

I see the same.
IMHO I understood where is the problem.
Scripts using windows, panels and toolbars gui.dll cannot be connected dynamically.
It is impossible to use command "dofile my_gui_script.lua". :(
That's why all scripts need to be placed only in SciTEStartup.lua. :(
For panels it is necessary to use only global variables.
It's a pity that we have to see panels constantly. :(
Commands "my_panel:show()" and "my_panel:hide()" did not work: (
Only commands "my_window:show()" and "my_window:hide()" work but I want to use panel instead of window.
That's I'm calling bugs.
I might be wrong but I cannot work in this way.

i think the version with onKey not very good because you have to press
another key to make the linechange visible...
i see also that there was an old/wrong regex for the pas-match-string
(pPff should be pPfF)

i have now included the handling of bookmarks_clearAll, which was also
not recognized by the old script

my functions-list is now sorted by name, the only thing i can't get
working is the replacement (look for replaceRegExp/replacePattern in
my code) of procedure by [p] and function by [f] and adding result-
type (in delphi after : ) in additional column

tabs also not working now :(

Try it two useful scripts:

http://mozers.net.ru/scite/FileManager.lua works with original SciTE and SciTE-Ru.
Steve Donovan could use it as an example in a gui-ext.

http://mozers.net.ru/scite/FileManagerRu.lua works only on the latest version SciTE-Ru and traces any switching bookmarks with OnSendEditor function.

Is it possible to localize context menu items in FileManager.lua via scite.GetTranslation? I tried to do so but it seems that

 

 

my_panel:context_menu {
 'scite.GetTranslation(Show all files)|all_files',
 'scite.GetTranslation(Only current ext)|current_ext',
}

will only print the context menu items verbally as "scite.GetTranslation(Show all files)" and "scite.GetTranslation(Only current ext)" respectively.

Hi Steve,
i've reworked your bookmarkcode with some help from mozers, so that some
special cases also catched. the only thing i currently can't solve is
that the marker is not deleted when the text is deleted, but this seems
a scintilla-"bug" (extra-thread).

problems with your code:
- line-positions are not updated (if bookmarks moved by
line-adding/deleting)
- bookmarks are not deleted if file is closed

i have my code attached, because there are some events catched, simply
add gui_conf2.luad with dofile to your startup-script (gui_functions.lua
is loaded from there).

hope its useful for anybody

scite-GUI is very useful for me, but some suggestions
is there a possibility to make the tabs multiline and
change font to a smaller one?
can you implement a method to change existing list-items? currently i
delete and insert them :)
also buttons/checkboxes/radiobuttons/labels would be useful for me, and
i think its not difficult to add them (and splitter needed, only a
onclick-handler)
can memo switched to single-line?

btw.
your panel-in-tabpage-example helps me a lot, but i wonder about this line:

panel:client(w)

w is the panel on the tabpage, why is it aligned to client on the
side-panel? the parent is the tabpage and not the side-panel...
*confused* but without this line, the tab is empty. it takes me a lot of
time to get it working by found your code :( this line was the one i missed

but again, many thanks for this extension :)

Hi Steve,

I've tried to define a new window to call this by menucommand.

gui_conf2.lua:
require("gui")
win_parent = gui.window "Side Bar"
local text_path = gui.memo()
win_parent:client(text_path)

SciteUser.properties:
command.name.42.*=TestWindow
command.42.*=win_parent.show
command.mode.42.*=subsystem:lua,savebefore:no
#- command.shortcut.42.*=Alt+Shift+F

also tried with "win_parent.show()", but the window is not shown if the
menuentry is clicked, no error appers on the output pane.

what's wrong with my code?

thanks, it works

btw. @mozers: you have a function to show hide the side-panel, but the

win:show() and win:hide() only worked for the window.
They do not work for panel.

Panel can be hidden my_panel:size(0,0).
Then you can restore the previous size.

There is no possibility to check the current state of the window or panel.

File http://mozers.net.ru/scite/ext-gui.lua I frequently updated.
In it not only what have. There also that what we wish.

i use your code with size() to hide the panel, but it's not hidden in
that moment...i have to click on it, then it's hidden.

function SideBar_hide()

Sorry for the silence, I was away for two weeks. I haven't found a new

Excellent, I shall look at it - I do want to give a good set of new

This can be done, and it will be possible with the next release.

AFAIK that seems to be the standard method of doing this - could add a
fake method which does this under the hood.

The question is whether we should wrap all the basic controls, so
people can use them as they see fit.

That's reasonable

The client call is necessary when using a tabpage, which is not a
container, but a set of clickable labels. This call just sets it up
initially, thereafter clicking the tabs causes a client call
internally.

Ummm... I'm a noobie when it comes to SciTE, Lua etc and I simply
don't understand how I use SciTE-GUI. It looks like a *very*
interesting addition to SciTE (which I already love).

Here's what I do understand -

To use SciTE-GUI requires that you have the associated DLL - gui.dll I
believe - in the same folder as the SciTE executable;
SciTE-GUI works only on Windows ( :( ) I run Linux at home and would
*love* to see a Linux-compatible version of SciTE-GUI;
SciTE-GUI involves "running" Lua programs.

That's the some total of my knowledge! :( Can someone please tell me
in idiots English how I get a sample SciTE-GUI program working?


Yours in admiration of SciTE and SciTE-GUI.

Dear Steve

I am very grateful for this little addition to sciTE for windows. Using the examples I have a minimalist file manager side panel - not a separate window. I have a few problems:

1. "There are some irritating repaint problems with the side panel splitter." - from your help page - any chance of a fix?

2. I have tried mypanel:size(0,0) and gui.panel() to close the panel and this seems to run into the same repaint problem (if I resize my window the panel does then minimize). Is there any way of completely removing the panel?

3. Some of my folders have many files - any way to add a vertical scroll bar?

4. Lastly in (an ideal world) I would like to specify foreground, background, selected.fore and selected.back colours so the side panel matches my colour scheme. 

Kind Regards

Gavin

Very interesting as ive seen sidebars in othet forks of scite. This one would be a nice approach.

Hi

I found a newer version with a modification of your code to provide new functionality including the ability to close the panel:

https://github.com/Konctantin/scite-ru

Reviewing the code there is a new check for the gui.set_panel() function with no arguments - which closes it!

if (! lua_isuserdata(L,1) && extra_window != NULL) {

extra_window->hide();

extra_window = NULL;

extra_window_splitter->close();

delete extra_window_splitter;

extra_window_splitter = NULL;

shake_scite_descendants();

My major problem is solved.

Kind Regards
