emacs-eaf / eaf-pdf-viewer Goto Github PK

Hi,

Is your feature request related to a problem? Please describe.

No

Describe the solution you'd like

I'm using the feature that synchronizes from LaTeX file to PDF file (nice feature btw), and think that it would be very useful if Pdf-viewer can display a tooltip over the Pdf page to indicate the corresponding parts between Pdf and LaTeX files.

This feature is currently supported by pdf-tools: https://github.com/politza/pdf-tools/blob/c510442ab89c8a9e9881230eeb364f4663f59e76/lisp/pdf-sync.el#L675

Here is the screenshot of pdf-tools:

It would be very nice if EAF Pdf-viewer can support it too.

Describe alternatives you've considered

I tried to bring the code from pdf-tools over EAF Pdf-viewer but wasn't successful.

Describe the bug
If the number of pages in the PDF changes and the viewer reloads the PDF, it will reload it with the old number of pages, either making pages at the end inaccessible or showing empty blank space and throwing an error.

To Reproduce
Using AucTeX and the LaTeX package lipsum:

1. Create a new TeX file called containing the following text:

\usepackage{lipsum}
\begin{document}
\lipsum[1]
\end{document}

2. Build the file and open the PDF in eaf-pdf-viewer. It should be 1 page long.
3. Change the line lipsum[1] to lipsum[1-10].
4. The PDF auto-reloads but only shows the first of 2 pages.
5. Close and reopen the PDF in eaf-pdf-viewer. It should now show both pages.
6. Now change the line lipsum[1-10] back to lipsum[1].
7. Again, the PDF auto-reloads but now it is possible to scroll into the blank space beyond the first page. The *eaf* buffer displays:

Traceback (most recent call last):

QBackingStore::endPaint() called with active painter; did you forget to destroy it or call QPainter::end() on it?

Expected behavior
When reloading the file, eaf-pdf-viewer should re-check its page count and display the file appropriately.

Describe the bug
I am using eaf with emacs 28.1 on windows 11.
eaf is the latest version as of 4/11.

When read_mode is set to fit_to_presentation, the pdf screen display does not change even if the page number displayed in the lower right corner of the screen changes, and vice versa.

Also, when a pdf file is opened with read_mode set to fit_to_presentation, scroll_up_page and scroll_down_page do not work frequently.

Screenshots

Hi,

Describe the bug

I use the dark theme background mode and configured EAF pdf-viewer in the follow background mode.

When adding a highlight annotation and saving it to the PDF file by M-h, the background of the corresponding page is also saved as the current dark theme background of Emacs.

To Reproduce

• Open a PDF file by EAF pdf-viewer in Emacs with dark theme background and follow background mode.

• Use mouse to select a text, and then press M-h to highlight it.

• Open the PDF file by an external PDF viewer, such as Okular, then you can see that the background of the PDF page containing the annotation is charged (see attached screenshot)

Expected behavior

The page background should not be changed.

Versions (please complete the following info):

• Distro and DE/WM: Linux Mint XFCE 20.02
• Versions of Dependencies: EAF pdf-reviewer revision: 100d1cd
• M-x emacs-version: 28.05

Screenshots

The background of the last two pages is changed. They should not be.

• If EAF was working correctly until a recent git pull, please refer to Mandatory Procedures to Keep Your EAF Up-to-Date first.
• Please check the *eaf* buffer, if there is any error shown in the *eaf* buffer, paste it here.

As the title says, how can I change the black bg to be consistent with my light theme? Thank you!

Screenshots

In presentation mode (M-p), scroll_*_page functions don't do anything (expected result: these should scroll a page), because the amount of scrolling is not calculated correctly, in the expression self.rect().height() - self.scroll_step_vertical, the two terms cancel each other out.

I could fix this issue by this simple hack, because scroll_up and scroll_down do work correctly:

    @interactive
    def scroll_up_page(self):
        # Adjust scroll step to make users continue reading fluently.
        if self.presentation_mode:
            self.scroll_up()
        else:
            self.update_vertical_offset(min(self.scroll_offset + self.rect().height() - self.scroll_step_vertical, self.max_scroll_offset()))

    @interactive
    def scroll_down_page(self):
        # Adjust scroll step to make users continue reading fluently.
        if self.presentation_mode:
            self.scroll_down()
        else:
            self.update_vertical_offset(max(self.scroll_offset - self.rect().height() + self.scroll_step_vertical, 0))

Run git pull and .install-eaf.py and the problem persists.

Describe the bug

EAF-pdf-viewer can successfully open if the LaTex file is compiled for the first time. But it cannot be reopened when the LaTex file is changed and recompiled.

To Reproduce

• Open a LaTex file and compile it.
• Make a random change to the LaTex file and then re-compile it

Expected behavior

PDF file is reopened with the newest changes.

Describe the solution you'd like
I wonder if EAF has a way to support occur-mode. The use cases are as follows: EAF already supports incremental search similar to iSearch, which is fast and has a good experience, but it takes a jump forward to know if it is the search place you need.

Sometimes we may prefer to choose from a series of search results (such as Blink-Search or Consult does).

Describe alternatives you've considered
Pdf-tools does a similar job:
For example, when I wanted to know how to measure performance, so I searched "measure performance", I got a list of results, and I could jump back and forth at will with follow-mode on the right.

And I think this one is useful not only for reading pdfs, but also for eaf-browsers(such as occur on current page) etc, we could get a global-view and just pick someone.

Thanks for the wonderful eaf-project!
Season's greetings.

Hi and congratulations for this amazing package, I'm blown away. The pdf viewer is great, but I'm missing synctex integration. This is in two parts: first, jump from a latex buffer to the position in the pdf, and second jump from a pdf to the latex buffer

使用 eaf-pdf-viewer 打开一个 pdf 文件之后，如果直接调用 C-x 3 左右分屏，则 pdf 文件的缩放不会立刻适应页面宽度。

(Just a note here so that I won't forget. I'll implement it later)

Hi,

Is your feature request related to a problem? Please describe.

Currently, if I accidentally delete a note, there is no feature to undo my action, hence I cannot recover the note.

Describe the solution you'd like

It would be nice if EAF pdf-viewer can support undo/redo action.

(However, I think it is quite challenging to implement as we need to maintain a state of action sequences)

Hi,

Is your feature request related to a problem? Please describe.

When I use EAF pdf-viewer to open a PDF file generated by LaTeX, and double-click on the PDF file, I see that EAF pdf-viewer can synchronize backward to the corresponding LaTeX buffer: it opens the LaTeX buffer and locate to the corresponding line of LaTeX source code.

However, after Emacs jumps to the LaTeX buffer, it immediately jumps back to the EAF pdf-viewer buffer.

Describe the solution you'd like

Is there a way to make Emacs stays in the LaTeX buffer?

Describe alternatives you've considered

I looked into the code of buffer.py in EAF pdf-viewer and see that the function below is called:

eval_in_emacs("eaf-pdf-synctex-backward-edit", [self.url, page_index + 1, ex, ey])

and eaf-pdf-synctex-backward-edit does select the buffer correctly.

However, I don't know why after executing eval_in_emacs, the EAF pdf-viewer window is selected again.

Hi,

Is your feature request related to a problem? Please describe.

It would be very nice if EAF pdf-viewer can also support inline text annotation. With this feature, I think it will become as good as the existing PDF viewers in Linux.

Describe alternatives you've considered

I look at existing features, and EAF pdf-viewer seems to support only popup text annotation.

Very fast and very nice viewer. But, wondering if a new feature is possible, since it makes, in my opinion, viewing a pdf presentation much easier.

I would like to force EOF to only show 1 page in the pdf file at a time, and then have a keystrokes that let you move up 1 page, or down 1 page. Right now the "page" movement slowly shifts such that you are looking in the middle of pages.

Thanks!

Describe the bug
When I use eaf-pdf-viewer to open a single-page pdf generated by LaTex, it is wrongly rendered as shown in the following screenshot.
The pdf is rendered by wps pdf without any errors.

To Reproduce
Just open a single-page pdf generated by LaTex.

Expected behavior
Many pages are shown.

Versions (please complete the following info):

• Distro and DE/WM: Manjaro i3

• Versions of Dependencies:

• M-x emacs-version: GNU Emacs 28.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.34, cairo version 1.17.6) of 2022-09-12

Screenshots

Additional context
This is the single-page pdf shown in the above screenshot.
tikz_scratch.pdf

Not sure why, but it happens quite often when I edit/compile my LaTeX files.
If the compilation fails, then Pdf-viewer may terminate unexpectedly since the generated PDF file is corrupted.

I'll look to see if I can fix this problem.

使用eaf-pdf-viewer是为了追求全键盘，README中介绍了复制文本是 M-w，但是选择文本我还是只能用鼠标去选择。
请问是否能纯键盘去选择文本？
非常感谢您的插件！

Describe alternatives you've considered
I have configured it with Auctex, and it is working as expected. I come from a pdf-tools background, it works much better than pdf-tools in fact I love to use dark mode to view the pdf. The only thing that bothers me is the accuracy of "Double click the left button to edit backward" which is only showing the line but not the word, but in pdf-tools, it was accurate up to words in most cases. In fact, auctex supports this accuracy. It would be great if EAF could be configured to word-level accuracy for reverse searching.

Describe the bug
The visual response lags a bit when I try to select parts of the text

To Reproduce
Repeated selection of parts of the text (if you combine scrolling with selection, this problem becomes more apparent).

Expected behavior
The visual response becomes more smoothly, just like in the Okular.

I use modus-themes, with white background for sunrise, and blackground for sunset.

Config related eaf-pdf-viewer:

(setq eaf-pdf-dark-mode "follow")

If current background is white, When I open a pdf file, the color do not display correct, I need to press key i to toggle inverted mode.

If I change theme to black background, `modus-themes-toggle', re-open the pdf file, the display was right.

If I set eaf-pdf-dark-mode to force' , the display behavior same as follow'.

Hi,

Is your feature request related to a problem? Please describe.

Currently, EAF pdf-viewer can support only the original background color (often white) or inverted background color (white -> black) of a document.

I cannot set a custom background color (In pdf-tools, I can do so by setting the background color in mid-night mode)

Describe the solution you'd like

It would be nice if EAF pdf-viewer can support the custom background color of documents (so that this background color can match with the background theme of Emacs)

Describe alternatives you've considered

I looked into this code of buffer.py and see that the inverted color is controlled at the pixel level by the function call pixmap.invertIRect(pixmap.irect) to PyMuPDF.

    def with_invert(self, invert, exclude_image=True):
        ...
        def fn(page, pixmap, scale):
            pixmap.invertIRect(pixmap.irect)

I haven't figured out how to make PyMuPDF only render text in inverted mode and set the background according to users' preferences.

Is this possible to implement such a feature in EAF pdf-viewer?

Describe the bug

使用 auctex 编译文件， eaf-pdf-viewer 预览。
当文件中包含大量中文且页码很多时，第一次编译顺利通过且预览顺利。
但是稍作修改后第二次编译，PDF 文件顺利生成，但 eaf-pdf-viewer buffer 就显示空白。

查询资料后发现是pymupdf依赖没有安装好，于是使用pip命令加--break-system-packages强制卸载pymupdf和fitz，然后按照同样强制pip重装fitz和pymupdf，安装顺序为先fitz然后再安装pymupdf，但是问题依然没有得到解决。

我使用arco linux，emacs为29，python版本为3.11

Describe the bug
I drag and drop a PDF such as this one (I can provide other examples which fail in the same way) into the emacs buffer:

mwb_E_202201.pdf

The buffer goes blank. I do not have this issue with other PDFs, such as this one:

https://arxiv.org/abs/2002.01247

Previously both of these PDFs successfully loaded in eaf-pdf-viewer. However, in the process of trying out the latest pymupdf wheel (related to #62) these certain PDFs like the first one no longer load (but other PDFs like the second one work as expected). The eaf buffer shows the following error when I drag and drop the first PDF:

To Reproduce

1. Download the first PDF I included above.
2. Open emacs.
3. Drag and drop the PDF into the emacs buffer.

Here is a screenshot showing what I see after dragging and dropping the PDF:

Additional context
Add any other context about the problem here.

Open a lengthy PDF (hundreds of pages) and hold space bar ⇒ Memory usage will be increasing until a maximum value (all pages rendered and hold in memory). After rendering a few hundreds of pages, eaf-pdf-viewer will consume > 1 GiB memory.

I thought there is no handling of old pages that users cannot see, and it turns out to be one.

However, it doesn't seem to work?

It is called here:

And the code only pop the oldest one.

Is your feature request related to a problem? Please describe.
I've found that PDFs and epubs which contain links can't have the links followed when clicked in eaf-pdf-viewer. As examples, here are two documents which have this behavior for me:

PDF: https://arxiv.org/abs/2002.01247
This document has various links which can be clicked to navigate to parts of the PDF, like references at the end.

epub: https://creativecommons.org/use-remix/made-with-cc/
This document has various links which can be clicked on to navigate to things like endnotes in the epub chapters.

I see there are keyboard shortcuts m and f related to links, but they don't seem to do be following links or enable clicking of links.

Describe the solution you'd like
Simply allow for a link to be clicked and followed.

Describe alternatives you've considered
None.

(Just noted here so that I won't forget. I can fix it when I have time)

I am using eaf-pdf-viewer and auctex.

After TeX-view (C-c C-v), the focus switches from tex buffer to PDF buffer.
Is it possible to keep focus on the tex buffer?

如果要把本项目改造成一个独立的PDF阅读器，请问该从哪里改起？能否指教一二，谢谢！
