`-I` argument: support load-path customisation
Add -I dir to look up source files in other directories.
SyncTeX backward synchronization sometimes off-by-one
Our SyncTeX parser often jumps one line before the right position, but not always.
I don't know why, nor if this behavior also happens with the official parser.
SDL Window disables composition under KWin by default
Hello, first I would like to thank you for this great software! :)
Made editing LaTeX files in Emacs really pleasant experience.
The default behavior for SDL2 window is to disable composition if the Window Manager understands the hint.
KDE's KWin does (probably is in the minority). The workaround is to either set the environment variable:
export SDL_HINT_VIDEO_X11_NET_WM_BYPASS_COMPOSITOR=0
or execute SDL_SetHint(SDL_HINT_VIDEO_X11_NET_WM_BYPASS_COMPOSITOR, "0");
before creating the window as someone mentioned here: mosra/magnum#184 (comment)
Not sure what version of SDL you are targeting so I'm not expecting you'll add this line of code - just wanted to put it here so others may find it if they would like to workaround the issue with the env. variable.
Thanks,
Adam.
Single-threaded downloader
Tectonic uses Reqwest to download TeX data, and Reqwest uses a background thread for downloading data.
On Linux, stopping the thread before forking was sufficient to get a correct behavior.
On macOS, forking is not possible from a multi-threaded process.
TeXpresso needs another backend. My thought:
- create a downloading process, by forking early during the initialization
- define some ad-hoc protocol that workers can use to request files from the downloading process
Cannot run test: [bundle] error loading resource latex: not found, Segmentation fault
Hi, thank you for your work on this!
I'm trying to run the test on Ubuntu 22.04 on WSL.
Installation seems to work fine, except for some warnings:

TeXpresso for Windows 11
Recently, a vscode extension for TeXpresso has been released. It is mentioned that
TeXpresso needs to be installed separately to use this extension, following its install guide which contains instructions for macOS, Fedora, Arch Linux, Debian, and Ubuntu.
Certainly, the number of users of Windows is large. I hope TeXpresso will soon have a release for Windows. Thank you so much for your consideration!
Question: Does texpresso works well on IEEE/Elesvier etc. publication template?

bug: Emacs does not see buffer changes for .tex files which are below symlinks
My system has directory a that is in fact a symlink to b. If I edit a/foo.tex using Emacs, texpresso does not see the updates unless I use M-x texpresso-signal explicitly. Editing b/foo.tex works as expected.
(I have not tested what happens if foo.tex itself is a symlink.)
Broken references and citations ?
Hi,
I managed to compile texpresso and texpresso-tonic on my Mac version 14.6.1 using rust 1.80.1
To compile texpresso-tonic, I followed the recommendation found here: #70
to update time from version 0.3.34 to version 0.3.36.
The command
./build/texpresso ./test/simple.tex
gives me a window with the compiled .tex file that appears correctly.
However, as soon as I try to include references to sections, tables, figures, equations, pages, or try to cite references with bibtex, the file is created and displayed but I only get '?' instead of references.
On the other hand, if I call texpresso-tonic instead of texpresso, the references work, but the window no longer appears.
Is there anything special I need to do with texpresso to be able to use references and citations ?
Thanks !
Aborts on test
It compiles, but when trying to run the test I get an abort and a coredump (NB: the "IOT instruction" means SIGABRT).
I run Arch btw. The same behaviour occurs when running texpresso installed via the PKGBUILD.

ELF object binary architecture: AMD x86-64Dynamically change loaded document
Right now the only way to display another TeX file is to start a new process.
Having a command to load a different document without restarting anything, recreating a window etc, could come handy.
Adding file to the filesystem can cause crashes
If TeXpresso tries to read foo.tex (for instance because it is processing \include{foo.tex}), when foo.tex does not exist at first, and it is then created, TeXpresso will crash.

VIM mode
It would be nice to have a (neo)vim mode :).
It is probably quite easy on TeXpresso side (one would have to implement a parser for sexp-based TeXpresso protocol, that I should document!), but requires someone knowledgeable with (modern) vim internals.
Language Server Protocol support
Hey!
I see that texpresso supports multiple different editors via ad-hoc plugins made separately for each one. Would it make sense to unify the interface and provide texpresso as an LSP?
This way, it would trivially work with many different editors with no need to add support one-by-one. And the LSP interface seems sufficient for texpresso's functionality.

SyncTeX: indicate when a file is closed
There is no way usinc SyncTeX output to tell when we are done with an input file.
This can be a problem when forwarding a position from the editor: if the position is beyond the last line reported by any SyncTex entry, TeXpresso has no way to tell when it can stop searching, until reaching the end of the whole document.
This is wasteful for large documents, and it can happen a lot when the document is split in multiple files.
A solution would be to add a SyncTeX entry indicating that an input file has been closed.
Alternatively, TeXpresso could record when it receives a "close" request and correlate this with SyncTeX output, but that is much more complicated.
Root file should exist or TeXpresso will just give up
When starting the process with texpresso foo.tex, foo.tex should already exist.
This is understandable when used as a standalone viewer, but not ideal when remote controlled from an editor: the buffer might have been created in the editor but not yet saved on disk.
TeXpresso protocol allows the editor to communicate the contents of the buffer without writing to disk, however the file name should at least exist on disk (a simple touch foo.tex is sufficient).
When remote controlled, TeXpresso should not exit and rather behave as if the file existed and was empty (waiting for the editor to communicate the actual contents).
Error when opening texpresso in WSL
I installed texpresso in WSL.
But when starting build/texpresso test/simple.tex, I get the result

missing dependencies in Ubuntu install instructions

Error report: batch changes and compute delta
Logging of TeX messages to the editor is almost append-only: during a run, content can only be appended, but when backtracking the current output is truncated, before appending again.
To prevent flickering or accidentally scrolling the output, it is necessary for the editor to wait a bit before reflecting these changes.
The heuristic implemented by emacs mode is to truncate only at the end of a run, and replace the output line by line during the run. This provides a decent look'n'feel, but can still feel slow if the output is updated too fun, without any benefits (e.g to receive 100 lines, it can be the case that the editor refresh the screen 100 times, once per line).
This heuristic with extra batching (e.g. wait for a buffer to fill up and delay updates by a bunch of milliseconds) is probably better implemented in TeXpresso itself rather than in the editor mode. Furthermore, if other editors were to be supported in the future (e.g. (n)vim), it is better to place as much logic as possible in TeXpresso itself.
Workaround for SyncTeX and (fragile) Beamer slides
When fragile, Beamer uses an intermediate file to temporarily save the content of the slide.
This cause SyncTeX to incorrectly report the location of this file rather than the original source. This file will have disappeared by the time SyncTeX output is processed, and the same filename is used for all slides, so SyncTeX is useless in this situation.
However TeXpresso has a detailed view of the whole process: when the files are created and removed, and which instance of the file was "alive" when a specific SyncTeX instruction was emitted. By correlating all these informations, it should be possible to recreate an approximate location of the actual source.

BibTex support?
Hi,
Thanks for the nice work! I am trying to use it for a journal paper, but it doesn't properly render the citations (I use .bibtex). Here is the template package I am using: https://www.ctan.org/tex-archive/macros/latex/contrib/mnras

Use sequence alignment to refine SyncTeX position
The source positions reported by SyncTeX are quite imprecise (one could say they suck :P).
Once we have a located the candidate lines (a mapping from a range of lines to a range of pages), we could use a sequence alignment algorithm to find a fine-grained mapping from source code characters to DVI characters.
UI: Display a spinner during initialization
On first start, TeXpresso downloads necessary TeX/LaTeX files from Tectonic repository.
This can take some time, during which TeXpresso appears to be frozen.
We should display some information or a spinner to keep users waiting.
One difficulty is that there are two sources of downloads and none of them have an easy to display information:
- from tectonic process downloading packages and metrics
- from renderer downloading graphical resources (mostly fonts)
On tectonic side, we have no direct connection to the UI. On renderer side, we are in a synchronous function waiting to load a font, from which it would be difficult to update the window.
As a first approximation, I am thinking to display a simple spinner with a fixed message when there is nothing else to display (document is being processed and no page has been produced yet).
viewer feature suggestion: secondary view windows
(This is not an urgent feature request, but something I thought would be nice in the long run.)
When working on a scientific document, it is frequent to navigate through the document to go back to a part written before. (For example: going back to read a definition, or the statement of a theorem, or a figure that we are now discussing.)
When using texpresso, it is tempting to always keep the viewer centered on the part of the document that we are actively editing.
To resolve the tension between these two needs, it would be nice to have support for opening several independent view windows onto the same document. (If the logic in texpresso is optimized to incrementally re-render only a single viewpoint, I think it would be fine as a first step for "secondary" widows to not show live updates.)
It is possible to realize this today by launching a separate PDF viewer to use as a secondary window and go look for definitions, figures etc. But if the texpresso viewer eventually gets support for clicking references/links to follow them ( #35 ), then that feature would naturally interact with multiple windows -- I may want the click to create a new secondary window to show the reference content, keeping the main window focused on the edition point.
PDF graphics interpreter: handle shading, XObjects
Our PDF graphics interpreter only handles basic primitives.
TikZ/PGF (and hence beamer) often uses shading. The difficulty with this is that is it not done using new instructions (that we could implement), but by defining and referencing resources external to the instruction stream.
Our interpreter lacks both features: no notion of resources, no way to define nor reference them.
Install problem
What is the cause of this error and how can I solve it? Thanks!

Race condition with sub-processes
Snapshotting is done by forking the TeX process (the worker) at relevant points. All processes share the same line of communication, a bidirectional pipe.
A parent wait for their child to finish before resuming communication, therefore at any point in time, the pipe is morally owned by the most recent child process. In the meantime, the TeXpresso driver can also decide to kill sub-processes if their work is no longer needed.
This happens to cause race conditions that are difficult to precisely pinpoint. Fortunately they happen quite rarely, but the end result is a desynchronisation between the driver and the workers (guesses: partial writes by workers on the communication pipe, likely due to the delay between the decision to kill a worker and the kill signal being delivered).
Short term: Right now, the driver aborts when this happen. It would be better for the end-user if, after logging the error, it stayed alive and restarted document processing from scratch.
Long term: The shared pipe approach is inherently brittle, I am tempted to switch to UNIX domain sockets and pass a unique FD to each worker.
On top of robustness, this would simplify the workers implementation since they are relieved of process management. Each could work in isolation, with the driver being the only one aware of the running jobs.
It would also fix the linear nature of the current snapshots. By using only fork and wait, processes always form a stack: the last forked process will be the first to finish ("LIFO"). This is not efficient when processing long documents: when editing the first pages, it might seem relevant to fork the worker. Editing the following pages, a new fork might seem relevant again. Etc. We keep forking, but if we never go back, we keep pushing on the stack and there is no opportunity to cleanup the processes: either we abuse resources (processes and memory), or we have to decide at some point to backtrack, cleanup the stack, and start processing the document from an old checkpoint, temporarily making the application unresponsive.
Cannot locate package libmujs-dev, cannot run test
I am on Ubuntu 20.04, which is one of the tested environments. When running the command to install all dependencies, I get the following:
Note, selecting 'libfontconfig1-dev' instead of 'libfontconfig-dev'
E: Unable to locate package libmujs-dev
I tried to proceed with the installation, to see whether the package was in fact needed. The build succeeded. However, when running the test, I get the following error:

\cite not work
Thank you for the amazing project!
But I meet problems in citation. I use \cite to cite references in .bib file. References can't be found in TeXpresso. The same project works well in Overleaf.
SyncTeX forward synchronization
SyncTeX backward synchronization is implemented: our quick'n'dirty synctex parser does a good enough job that we can find source files when clicking on the window.
Synchronizing in the other direction is more complex because there needs to be coordination between synctex and the engine (progress as long as the forwarded position has not been found), and it should happen concurrently (the GUI should stay responsive) and be cancellable (maybe the position is nowhere to be found because it refers to a file that is not used in the document; the user will move to some file and we need to resume work as if nothing happened).

Downloading new Tectonic files is broken
When using a new package or a feature that requires downloading new resources to the tectonic cache, TeXpresso is likely to freeze.
This is likely because of a bad interaction between forking and downloading: the socket used for downloading files will be shared by all fork of the worker, quickly leading to corruption.
It could also be the cache that gets corrupted: file A is missing, process P2 is forked from P1, P2 downloads A, later P2 dies and P1 is resumed: it still thinks A is missing from cache, potentially corrupting some internal state. (Less likely, downloading file should be idempotent, so at worst the file is downloaded twice).
I am not yet sure how to address that: tectonic code needs to be instrumented to close the downloading socket after a fork. The drawback is that we might start more short-lived TCP connections to download files. This is probably not a problem (it happens at most once per file, and this is already what happens when using tectonic -X bundle cat).
Alternatively, this could be handled by forking before downloading, so that a single downloading process is shared by all the workers. The drawback is more IPC.
I tend to favor the first option (short-lived TCP connections).

vscode editor support
Hey!
Nice to see this project! I seen texpresso support Emacs and Neovim.
Have any plan to support vscode?
Yin
Clicking on references/links?
Does the TeXpresso viewer support jumping to the destination of a reference?
(When working on scientific LaTeX documents it is very useful to be able to follow references, and also to have a shortcut to go back to where we where before following it.)
Snapshot positioning is too naive
To observe the problem:
- Edit a line by inserting contents, from left-to-right, for some time
- Go up a few lines, and start editing from that point.
Step 1. will happen smoothly: when adding consecutive characters, a snapshot very close to the text caret is ready to reprocess the current page. Step 2. is likely to cause a slowdown: not problematic, but enough to be observable (100-200ms on my tests).
This situation should be better handled, for instance by keeping a snapshot close to the beginning of the page. The problem is that right now, the positioning is too naive: even if we keep enough snapshots, they are either too close or too far.
Not able to install
Hi! I am using Ubuntu22.04 and failed to run the testing document. And here is my guess:
The first time I tried building the project, I found myself missing tesseract:
...

...Even after I installed tesseract using sudo apt install tesseract-ocr libtesseract-dev and re-cloned the repo, I still failed to run the testing doc. When I tried the testing doc, I got

and the window just popped up and shut down immediately. This was the same both with and without tessetact installed.
Many thanks if you can help out!
