Added the required preprocessor directives to make building without epub support possible.
|
|
Resolved the issue with epub document where the documents were not getting finalised. My bad, sorry, I fix that with this commit.
Also it seems I had set the wrong permissions on ev-view.[c,h]. Also fixed that.
|
|
I came across a document that didn't have an old style toc, and thus the all accomodating navsheet support.
Also fixed some mistakes here and there.
|
|
Added the capability to view and epub document with inverted colors, yet to test for documents where we write the stylesheet, although the code is there.
|
|
Added the function to handle links from the toolbar, also added functions to disconnect all ev-view handlers once it has been replaced by ev-web-view, and vice-versa(to drop all handler associated to ev-web-view).
Also the unref call to job_thumb was causing thumbnail jobs to crash with GTK2, so had to revert that, now we're back to the document folder not getting deleted from disk.
|
|
I added the code to make it possible to build Atril with GTK3 and webkit2. Everything runs fine with both GTK3 and GTK2. The find module for epub was also tested and changed. Now I shall first attempt to fix some Glib errors, and the problem of the temporary directory not getting deleted, that arose when I stabilized the thumbnails.
|
|
You can now search through the entire epub document. In the next commit I'm adding support for webkit2 with gtk3.
|
|
No more crashes when searching with the sidebar open, will probably add a pixbuf cache as well to speed it up even further.
The process which I earlier thought was not possible without separate jobs, work just fine as a single job, if I change the run mode of the thumbnail job, and incorporate a trylock() in case of epub.
|
|
I added the capability to search through documents. The search is quite buggy, and we'll be taking care of each bug one at a time.
|
|
The documents can finally be read alongside a TOC, I tested it with a variety of documents before this commit, so I presume it should work with all. Also fixed the part where I had screwed up PDF annotations owing to a wrong call. In the next commit, fully functional searching would be up, using HTML parser of libxml in combination with webkit.
Also some other minor changes.
|
|
..and other fixing other bugs that were present once the webview was added, like the escape key command etc. Will look to refactor the thumbnails into ev-web-view.c.
In the next commit I'll extend this search over the entire document.Also will incorporate document index(table of contents).
|
|
Alebit with a bit of bugs as far as navigation etc. are possible, we can read an epub document in Atril.
The document will be displayed with thumbnails, and all keyboard shortcuts work.
Menu options, the ones that I have currently added do work.
I Will now move on to features such as inverted colors, document index, etc, most of which should be simple to add.
Also made changes so that the presentation view does not fire up while displaying an epub document.
Also added the feature to copy text to clipboard using the Atril menu.
|
|
Fixed the backend epub_document_finalize function which was caused caja to crash when you opened the document properties dialog.
Fixed the ev_window_dispose and the webview's dispose and finalise functions, now the window closes without any glib-critical errors.
Also now it is possible to read epub documents, once you have changed pages at least once, I still have to figure out where I call load_uri at document load.
|
|
Added zoom-in and zoom out capabilities, also re-enabled window thumbnail which I had disabled previously when the thumbnails were not implemented.
Still trying to get the document to display, need to make the right changes, also trying to stop the window from entering presentation view, but that does happen and needs to be fixed.
|
|
Select all functionality to select all content from the webview.
Cleaned ev-jobs.c, it had a lot of unused code.
|
|
Passes the test with a 71 page epub, I don't think it would have much problems were we to scale it further.
|
|
The loading icons for all thumbnails are displayed, but the program does not segfault. Also realized that the absurd resizing of the window was due to the ephy-zoom action on the webview window. Will fix that in the next commit. Will also think of some workaround for screenshots.
For now committed this code so that this can act as a clean slate if I screw up somewhere.
|
|
Including creation of windows, webviews etc., still get a crash. The one page epub works fine with the thumbnails though.
Also fixing some calls which cause gtk-critical errors when I try to close the window.
|
|
Properties dialog for epub documents, will some basic properties.
Also set toolbar and menu sensitivity for the actions available in epub, will add more(find) once I write the module. Also inverted colors needs to be done with CSS or the like.

Now other problems with webkit. After much fidgeting I was able to resolve the previous problems of threads. However, now there is a different webkit error.
|
|
|
|
My last commit was supposed to have ev-web-view.c and ev-web-view.h however due to some reason I missed them last time, so here they are now. i am able to achieve thumbnails for my epub however these are of absurdly large size. Still struggling to get the webview done due to thread problems that I am encountering.
|
|
Earlier my approach was to replace the atril view directly with a webview. However as it turned out it was extremely difficult to accomplish much tasks without the document-model. So I created an Extension of the WebKitWebView class, EvWebView so that now we can manipulate the webview as desired. Also having a separate file really helps in terms of clarity.
Please note that there are many empty functions and TODO tags right now, I shall aim to fill these up once the display part is done, probably in this week.
I also added some code on the backend to draw thumbnails when with GTK+-3.0, although I have never tested a GTK+-3.0 build.With GTK+-2.0 you won't get any build errors, however epub backend won't work right now.
That being said, this commit is mostly because there was a lot of code that was lying in the local repository, and it was best to back it up as a failsafe.
I modified ev-window to accomodate this new data structure, and having an equivalent ev_web_view function for every ev_view function, I can achieve most functionality by filling those functions with Webkit modules.
Other than that on the backend
Other than that there were some minor changes to the code.
Although I did the above, currently I am not able to instantiate the EvWebView because of some class and object type definition errors, due to which I can't display the document.

- Modified configure.ac to use both webkit2 and webkit1 based on gtk version
- Modified Automake file in help/reference/shell/Makefile.am to compile with gtk-doc
- Modified ev-document-model to support epub-documents.
- Modified ev-window for epub documents.
- Modified jobs so epub pages are not rendered.
- Modified ev-document, although I'm not sure if this is necessary.
Still need to figure out where the web view load uri has to be called to actually load pages, from there the puzzle would be much simpler. Hope to get this done in the week, and pick up the pace now that only six weeks of coding remain before final evaluation.
