Several questions about LDT [message #1416672]

Hi,

I'm trying LDT right now (0.8 and 0.9 versions). Can't make outlining working. It shows only global variables. How to make it to show more members?

Also if to add any russian comment or text into source, variable highliting, syntax coloring, code assistant become broken. How to fix it?

And how to make code folding to work? It sometimes shows (-) for folding randomly in sources, but folds erroneous block if to click on (-).

PS: Sorry for my English :)
PPS: standalone LDT 32 bit 0.8 and 0.9

Hi Denis,

First, thanks for using LDT and to take time to post your feedback.

1) See following post which explain elements handle in the outline:
http://www.eclipse.org/forums/index.php/m/896827/?srch=outline#msg_896827

2) Does your Russian character need a special file encoding ? if yes, which one ?
So far, other encoding than UTF-8 are not really supported/tested in LDT.

3) As i know code folding is only working for top level blocks. If you have weird behaviors when folding code please attach a screen-shot or describe the way to reproduce it. If it's sure there is a bug, feel free to open an issue using following link: https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Koneki;component=LuaTools

Looks like it is enough to change non ASCII-charasters in sources into any ASCII-charaster before creating AST.

I added this to LuaSourceParser.java:

private static String prepareSourceTextForMetaLua(String text)
{
char[] chars = text.toCharArray();
for (int i = 0; i < chars.length; i++) if (chars[i] > 128) chars[i] = '?';
return new String(chars);
}

and did this:

public IModuleDeclaration parse(IModuleSource input, IProblemReporter reporter) {
LuaSourceRoot module = new LuaSourceRoot(input.getSourceContents().length());

synchronized (LuaSourceParser.class) {
try {
String preparedSource = prepareSourceTextForMetaLua(input.getSourceContents()); // change non ASCII charasters to '?'
module = astBuilder.buildAST(preparedSource); // and then create AST
} catch (LuaException e) {
Activator.logError("Unable to load metalua ast builder :" + input.getFileName(), e); //$NON-NLS-1$
}
...

and my problems with syntax coloring, variables highliting and folding has gone :)

PS: Russian charasters not need to be encoded only in utf-8. They can be encoded by windows-1251 which is one byte encoding, but the bug appears both with utf-8 and windows-1251 (without my fix)

Hi Denis,
I have some precision/correction about your problems :
1) We currently (v0.8.x) don't support UTF8 encoding, we only support ascii (one byte character exactly).
2) As you found by yourself, all problems about syntax coloring, variables highlighting and folding come from non ascii character in your source file. If you want to follow this problem, a https://bugs.eclipse.org/bugs/show_bug.cgi?id=376304 is opened.

As you could see, it's a serious problem and we https://bugs.eclipse.org/bugs/show_bug.cgi?id=384932 to fix it for the v0.9.0, but we did not found a good solution for now.
Your proposition is interesting but this means if there are non ascii character in code, outline content-assist and documentation will contains "?" char instead of the right one :/.
If we don't find a better solution, this could be the lesser evil.

Thx denis for your feedback and the code you post.

The issue called "Error markers and Variable highlighting problem with non UTF-8 source files" but it seems no matter which coding is used for storing text info files. The bug depends on non-ASCII charasters only.

Hello Denis!
If you try the latest nightly build (or make your own build ;)) you should have proper support for non-ASCII encoding!!

Hi Denis,
I did some tests and it's ok if you use LDT with the last eclipse platform (Juno), but it seems you find a regression with the indigo platform, I will fix that right now.

I see in another post you built the LDT project with the "platform-indigo" profile. This means you force the build to use an old eclipse platform. If you prefer the indigo platform you right to do that but if you have no preferences you should use the last one (which should be theoricaly better), in this case use just a "mvn clean install -P build-product"

I hope this will fix your encoding problem ;).

With "mvn clean install -P build-product" it stops on

Hm... Highlight and folding don't work for my startup.lua file:

local geo = require("geo")
local project = require("sys.project")

-- Подключаем отладчик для LDT, если он присутствует
if geo.is_file(geo.get_scripts_dir() .. '\\..\\lua_debugger\\lua\\debugger.lua') then
package.path = "..\\lua_debugger\\lua\\?.lua;" .. package.path
package.cpath = "..\\lua_debugger\\bin\\?.dll;" .. package.cpath
require("debugger")('localhost', 12345, '0000')
end

-- Инициализируем проект по умолчанию
project.init_project_by_num(0)
Other files seems are ok.

Hello Denis,

Works just fine for me with latest 0.9. I suspect you might be using 0.8...?
If not, please send more details in order for us to try to reproduce

Thank you!

I used latest 0.9.
Just try to create startup.lua file and paste text above in it. PS: I use UTF8 encoding for files.

Hi Denis,

It seems we are not able to reproduce the bug on the latest 0.9RC1 version. Maybe you can provide us more details about the steps to reproduce and/or the log file you can find under this path:
<yourWorkspaceFolder>/.metadata/.log.

Thanks,
Marc

Hm... I cleaned up the log, opened the file startup.lua and closed LDT. The log file stayed empty.
And I have no idea about way to reproduce. I just open this file.

Sorry, for the late response, but we still don't reproduce on our side.

Maybe, you reproduce the bug in a 0.9 release ?
And if you copy the content in a new file, do you have the same behavior on opening ?
