我简单试用了一下，中文乱码。
I had a try, Chinese garbled.
Nice work! I had a similar version as you can see in the first picture of this thread. To display a programming language with different styles was not very hard. The real effort of this plugin is to make a lot of things configurable for every language (as far as I remember). And of course you have to store and load that information. Even the indices (for the styles or languages) in SciLexer.dll are generated and will change from version to version (if new languages or styles are added). That was the point where I failed! Shame on me, I know! 
I wish you all the best and that you'll finish your goal (so that I can delete it in my mind)! Good luck!!!
As Leo sugested SciLexer.dll should be now in
C:\Program Files\GPSoftware\Directory Opus\ViewersCRT should not be necessary anymore.
USB export seems difficult.
Where should be x64 files located in x86 installation?
And how to copy config file?
<export>/dopusdata/dosv.config.xml</export>Will this work?
There is also log file created in Logs directory. Should it be disabled?
Should work now.
Config file was auto generated from notepad++ version, so some things does not work yet.
You can try javascript now. No html scripts, though. And I will think how to fix background color later.
IMO implementing this will demand some hacking, unless Leo could help?
What exactly is inconvenient?
Posting example file and screenshot may help. But if it does not work in notepad, chances are low.

I couldn't agree more.

Man it's aweseom! o) CTRL+Mousewheel also works to zoom in/out, great! o)
The config dialog is also much better now. I noticed, the bold/italics/underline checkboxes are not yet set correctly after choosing a style.
Another minor issue is the column of linenumbers, it does not resize, when zooming in, but not a big deal for me.
Regarding the find, I guess people are used to press F3 to repeat the search with what has been searched before. Currently F3 to search forward and SHIFT+F3 to search backward does not have any function. You need to enter the find-textfield and retype what you have already been searching for to make the find go on/work again. You also cannot use RETURN within the textfield to make the find move forward, you need to grab the mouse and hit "next" or TAB switch to the buttons on the right hand side.
After selecting a keyword, I also expect CTRL+F3 to work like "find next" for the current selection and CTRL+SHIFT+F3" to work like "find prev". These F3 key combinations are very common and a must have for serious handling, I guess you also know them from VisualStudio e.g. It would be awesome if you could make them work like there/described.
This viewer plugin really adds alot to the overall DO experience! Please keep going! o)
Sorry for the delay in replying.
There's not much that needs to be done, as long as the code isn't writing to the registry or anything like that.
In the same places as they are now:
(Note: /home is an alias which resolves to the Opus program folder, usually C:\Program Files\GPSoftware\Directory Opus.)
- On 64-bit HDD installs:
x64 DLLs go in /home/Viewers
x86 DLLs go in /home/x86/Viewers - On 32-bit HDD installs:
x86 DLLs go in /home/Viewers
x64 DLLs go in /home/x64/Viewers (This is new in Opus 11.12.5 and above.)[/li][/ul]
The HDD installs have copies of the other "bitness" so that they can export either or both to USB. (Priori to 11.12.5, only 64-bit installs had this capability. Now 32-bit ones do as well.)
Copying the plugin DLLs to USB sticks is done for you by Opus. Plugins do not need to worry about that. Opus will copy the appropriate DLLs to the appropriate place on the USB stick automatically.
The only extra thing you need to do is tell Opus that SciLexer.dll also needs to be copied, since Opus wouldn't know that extra DLL is part of your plugin otherwise. To do that, you just need to add it to the usbsafe.xml manifest details. The j2k plugin is an example that does this for two extra files. Here is its usbsafe.xml manifest:
As you can see, it just specifies a filename, so the additional files should be in the same folder as the plugin itself.
If you have extra DLLs or other files whose names are different on x86 and x64, the manifest can handle that as well. Here's how the Archives plugin deals with unrar.dll and unrar64.dll:
[quote]And how to copy config file?
/dopusdata/dosv.config.xml
[/quote]
Config files should be in the folder you get back from the GetConfigPath helper function. (Usually /dopusdata/ConfigFiles/Plugins.) As long as they are in there, they will be exported automatically.
Officially, the /dopusdata/Logs dir is private and it wasn't envisaged that plugins would write to there, so putting your own files in there may confuse some part of Opus (although it may be fine as well, I am not sure).
As far as USB installs go, it's the same on them as for an HDD install, as long as you are obtaining the config path via the helper API, or by asking Opus to resolve the /dopusdata alias. i.e. As long as you are not assuming the config folder is in the user's profile folder. (USB installs should not modify the user profile folder, since all the Opus config folders will be in another location in that scenario.)
I can try. I'm not sure what the question is, sorry. Do you need a way to map from a filename/extension to a file type?
By the way, if you don't have a licence with USB export enabled, I'm sure we can fix that for you to let you test things. Get in touch if you need it!
If you're in eval mode and don't have an Opus licence at all, we can sort that for you as well, if needed. We're happy to provide free licences to help with plugin development.
Thanks for help and suggestions @leo and @tbone.
USB export and shortcuts should work now. My main problem with manifest was that it was not clear for me that every config file from folder is exported (even if plugin does not support USB export).
To do what @tbone asked will require that information about extension of file currently displayed in preview panel should be accessible in configuration dialog. I understand why this will be problematic and suggest leaving this feature for now.

Hi gdobin! o)
I hope you don't mind this little issue-section?
- The font height seems to make problems and won't stay once set via the config dialog.
I edited xml directly to fix this, but the default setting still seems to fight with the font height of a specific filetype, or it's me doing something wrong.
Feedback to your recent enhancements:
- Background and coloring for js files is fine now.
- Find next/prev and related F3 key-combination work very good, great! o)
- Resizing of line number column works.
- Enter in the find textbox works good.
A few more ideas in descending importance from my wishlist o):
- Possibility to set a tab-width somewhere (I find a default tab-width of 8 blanks much to wide for browsing code).
- Possibility to scroll the text by mousewheel, though focus is still within the find textbox at the bottom.
- Possibility to reset the font-size to 100% (means standard font height). Maybe that also makes it easier to track down the font height issue, as I never know exactly wether it's the current zoom-factor being the problem or the font-size being set/read wrong.
Maybe a DO related topic:
- I did not succeed to use your plugin as a catch-all for any other ascii filetype, is this possible at all with DO?
I disabled the regular text-catch all plugin at the botton of the DO viewer prefs, but then I cannot look into text files anymore. I'd like to use the plugin for these files as well, numbered lines and highlighting of words is just to good to be missed! o)
This is another leap forward to perfection, thanks once more for what you did and share with us!
gdobin, thanks. Great work.
Not had much time with it but looks great so far. Will try to get more time over the next few days.
Hope you don't mind me asking. Are you able to share the source/repo?
Thanks again
Similar to Tbone, How would I make this this the default for all files? I have disabled the default text viewer. However some file do not display using this plugin.
for example:
- .aspx: preview as a icon.
- .xml: preview in IE.
- .stylecop: preview as a icon.
- .config: preview as a icon.
I have pro license with ftp and usb export, but free future updates will be nice.
Sorry, cannot reproduce this one? Could you post your config file?
Font settings are specific for every style for specific language. So for example, in javascript you could have comments smaller then keywords...
If you left font size field empty, font size will be set to value from "default" language.
You want to reset font size from config file or zoom level?
Just add lang "ascii" in dosv.config.xml and set some custom extensions.
Probably, after beta stage.
It is not possible and I doubt you really want to view binary files that way.
You should put DOSV above "ActiveX + Preview + Office + Web" plugin in Viewer Plugins panel (in Preferences dialog).
BTW. Is Text plugin broken? Why there are icons in preview panel instead of hex view?
[quote]Font settings are specific for every style for specific language. So for example, in javascript you could have comments smaller then keywords...

A specific example:
If I set font size to 16 via the dialog, for "javascript/default/courier new", the xml loses the font-height setting of "9" for the default file type, it is blank after doing so. Additionally the font size for the javascript files looks smaller than before (more like 8px), just the height of each line seems to be increased.

I meant resetting of the zoom-level from/of the viewerpane/plugin.
Did so testwise for *.txt, seems to do the job just fine, thanks for pointing me to that. o)
I guess this is the new setting of more recent DO versions, search for "display shell icons" and uncheck.
Found something new on my wishlist o):
- En/disable word wrap from plugin context menu
- Open xml configuration file from plugin context menu (in DOs default editor would be great)
And something on the issue side of things as well:
- The tag does not seem to make a difference for me, I cannot view files larger than about 10k currently (hu?)
It's always the default viewer that kicks in for larger files since I played with the FileSizeLimit value, even though I reset it to what it was initially.
Well, yours config file is a bit of a mess.
Do not change extensions of default language. There must be single star "".
You need to set size for every style for language if you do not want default font size.
And be default I mean default language (this with "") no default style for specific language.
And you skipped last "0" from FileSizeLimit. In result your new file size limit was ~18kB.
Thanks, but I still consider this being a bug 
dosv.config.xml.txt (188 KB)
The plugin should already knows the file path, since it has loaded the file, so it knows the file extension.
What's the missing part you need help with? Something to do with more than one viewer being open and knowing which one is asking for the config dialog, or something different?
Yes, multiple viewers are the essence of the problem.
I think this should work:
DVP_Configure is given a hWndParent argument. Find the top-level parent window of that, and match it to the viewer with the same top-level parent window. (Or, if there isn't one, you know you're being called via the Preferences dialog instead.)
Been using you add-in for a few days now. Its awesome. Thanks for taking the time to create it. Much appreciated.
Is this an editor or just a viewer?
Not "just" a viewer, an excellent viewer! o)
Any plans to add the editor function? I still have the original Scintilla source code editor plugin in a folder somewhere and it was SO handy when needing to make minor changes to a whole bunch of files.
