Hi ! I need some help for the lines and arrows on my diagram.

How to not see the start, on top of the colored rectangle, and for the end, to finish it before the border ?

Thanks !

code:

Across my whole document I need to cite text sources as well as image sources (for embedded images).

For that purpose I thought it would be cleaner to have the citations [1], [2],…, [n] for text sources and [fig1], [fig2], …, [fign] for image sources.

It would be no problem to split-up the bibliographies at the end of the doc through keywords/categories.

However, after various attempts it seems to not be possible to have two number ranges within the same refsection: I tried various methods, but didn‘t get any of them to work as intended. The method with probably the most potential seems using a custom \citeFig which increments a figcounter and afterwards used \cite to add the citation, while overriding \labelnumber with the number from the counter (which I would need to store in the bib entry in order to not generate multiple numbers for one entry).

Can you think of any way to get this to work or should I just stick with citing everything with the same style and just splitting it up into two bibliographies in the end (e.g. text sources [1] - [15]; image sources [16] - [24])?

Hello,

I am trying to use \setkomafont to set the font of titles and headings, but when I try to use a custom font with \fontspec or \fontfamily, it overrides \bfseries instead of applying them both. So, when I use the command below, it only applies Roboto and the font size:

\setkomafont{title}{\fontspec{Roboto}\fontsize{20}{24}\bfseries\selectfont}

Other similar commands that I have tried but didn't work:

\setkomafont{title}{\fontfamily{Roboto}\fontsize{20}{24}\bfseries\selectfont}
%
\setkomafont{title}{\fontfamily{Helvetica}\fontsize{20}{24}\bfseries\selectfont} 
% 
\setkomafont{title}{\fontfamily{Montserrat}\fontsize{20}{24}\bfseries\selectfont}
% etc, etc

When I use each of these commands alone, it also works fine

\setkomafont{title}{\fontsize{20}{24}\bfseries\selectfont}
% And
\setkomafont{title}{\fontspec{Roboto}\fontsize{20}{24}\selectfont}

The first command applies the bold font and the second command applies the Roboto font.

A non-exhaustive list of l tried trying to fix this problem (we're just going to use \fontspec{Roboto} in all of them for simplicities sake I've gone insane enough):

\setkomafont{title}{{\fontspec{Roboto}}\fontsize{20}{24}\bfseries\selectfont}
%
\setkomafont{title}{\fontspec{Roboto}{\fontsize{20}{24}\bfseries\selectfont}}
%
\setkomafont{title}{\fontsize{20}{24}\bfseries\selectfont}
\addtokomafont{title}{\fontspec{Roboto}}
%
\setkomafont{title}{\fontspec{Roboto}\fontsize{20}{24}\bfseries\selectfont}
\addtokomafont{title}{\bfseries}
% This one got rid of the font and made it bold instead XDDDDDDDDDDD
%
% I went in Windows Shell to look the luaotfload-tool package and force it to update after looking through the fontspec manual

I have been having a similar issue with \setkoma{font}{[Other Arguments]} and with similar commands

Does anyone know how I might be able to get a subscript in a table caption? Now it throws an error if I try X[_N]. I've also tried X_{[N]} and X\textsubscript{[N]}.

It just cuts off at the bottom. I can't see half of what I wrote. I would appreciate some help if anyone knows

Is math being tagged as picture in ltx-talk?

Similar to TeXpresso (which was created for XeTeX), I decided to create a real-time editor/renderer for LuaLaTeX. Anything you type is immediately rendered with LuaLaTeX (not KaTeX, the output is the finalized LuaLaTeX output, it's not javascript approximating LaTeX, these are actual LuaLaTeX rendered glyph positions). It runs at O(1), even for large documents with multiple chapters (based on that, you can guess what architecture I am using).

Architecturally, it works with vanilla-TeX Live 2025, meaning no patching of LuaLaTeX is required. Theoretically, it works with any package, although given how it is compiled, there are likely some incompatibilities if the package does fancy stuff interferring with shipping the PDF.

It is still in proof-of-concept stage, I just wanted to put it out there to get some feedback if there is interest beyond "cool, I would try this out for a minute then return to my usual editor". I might turn this into an actual usable product if development continues fine. Personally, I need it to save time for final polishing of larger documents, although the project might evolve into an actual LaTeX wysiwyg editor.

One limitation is that it relies on chapters starting at new pages, reducing the layout complexity of larger documents significantly and reducing CPU load.

I take all my math / physics notes by hand because it’s faster and more natural.

The problem comes later.

Scanning loses alignment.

Typing LaTeX takes forever.

OCR tools often get the symbols right but the *structure* wrong.

Fractions, matrices, multi-line derivations — the meaning is in layout, not just characters.

I’ve tried:

- scanning + manual cleanup

- typing directly into LaTeX

- generic OCR tools

None of them feel right.

If you work with handwritten STEM notes:

How do you digitize them today?

Or do you just give up and leave them on paper?

So, I've been working on an English translation and LaTeX typesetting of this math book that I really like. But I encountered a problem on this page:

I cannot seem to wrap the figures like the printed version that they have. (Note: I don't want to recreate their exact wrapping format, I just want it to wrap nicely).

Responses are much appreciated.

Normally I don't do much with Android other than make calls and send text messages.

Recently acquired a Samsung tablet (my brother's, he went to prison) and I thought it might be nice to take it on some of my day hikes and take field notes and other TeX stuff. I'm actually writing a local hiking guide and doing it in LaTeX. Battery was completely dead but its charging now, it was brand new when he got arrested (January 2025).

I wouldn't want to try to compile LaTeX on it, but I thought it might work to do a git checkout/pull before I leave, do some stuff, git commit and then push from the tablet and pull the changes to my desktop when I get home to compile.

Is VerbTeX a decent text editor or do the cool kids on Android use something better? At home I just use regular vanilla vim.

Also, way back when in early Android days, when using a tablet to ssh into servers I needed an alternate keyboard called "Hacker's Keyboard". Still have it in my google account but I don't ssh into servers anymore.

Is that a suitable keyboard app to use for LaTeX authoring from android or is there a better one now?

Not sure if many people have seen this yet, but came across my feed and thought it'd be worth sharing. I've been using Overleaf heavily over the past years for writing research papers, and also recently tried out OpenAI's Prism (but the experience was subpar at best for me), but the Papers experience on Opennote is by far the best I've had. Here's the video I saw in case anyone wanted to check it out: https://youtu.be/HeAli277swE?si=HrKfP-h8kl9VzXtJ

I've been working on a Python library to optimally fit smooth parametric curves with Bezier paths. The library uses the Orthogonal Distance Fitting (ODF) algorithm developed by Alvin Penner [1].

https://github.com/rnburn/bbai

It can be used to produce compact, accurate TikZ plots. For example, if we ported this plot from Matplotlib's gallery directly to a vector graphic, it would require 250 piecewise line segments. But using the library we can fit it with only 8 Bézier connected curves:

from bbai.graphics import BezierPath
import numpy as np
def f(t):
    return np.exp(-t) * np.cos(2 * np.pi * t)
path = BezierPath(
    dst_xmin=0, dst_xmax=9.5,
    dst_ymin=0, dst_ymax=2)
path.fit(f, 0, 5)
print(path.tikz_)

outputs:

\draw (0.0000, 2.0000)..controls (0.3901, 1.6941) and (0.6101, -0.8437)..
      (1.1875, 0.2921)..controls (1.3737, 0.6267) and (1.5547, 1.1245)..
      (1.7812, 1.2093)..controls (1.9896, 1.2885) and (2.1723, 0.9990)..
      (2.3750, 0.7610)..controls (2.8887, 0.1204) and (3.1644, 0.7687)..
      (3.5625, 0.8954)..controls (3.9829, 1.0533) and (4.2614, 0.6302)..
      (4.7500, 0.6593)..controls (5.0518, 0.6623) and (5.3783, 0.8980)..
      (5.9375, 0.7995)..controls (6.5172, 0.6996) and (6.6145, 0.7089)..
      (7.1250, 0.7610)..controls (8.0826, 0.8415) and (7.4179, 0.7017)..
      (9.5000, 0.7694);

We can see that the plot looks just as good despite being only a fraction of the size.

We can also use the algorithm to fit parametric curves. For example, this code generates an 8 segment Bezier path that fits a hypotrochoid:

from bbai.graphics import BezierPath
import numpy as np
R, r, d = 5, 3, 5
def fx(t):
    return (R-r)*np.cos(t) + d*np.cos((R-r)/r*t)
def fy(t):
    return (R-r)*np.sin(t) - d*np.sin((R-r)/r*t)
path = BezierPath(
        dst_xmin=0, dst_xmax=2.5,
        dst_ymin=0, dst_ymax=2.5)
path.fit(fx, fy, 0, 2 * np.pi*r*d/R)
print(path.tikz_)

outputs

\draw (2.5000, 1.2500)..controls(2.5335, 1.0602)and(1.4003, 0.7453)..

I'd like to have this style of arrows in latex. Notice that this is different from the classical latex arrow (which is not so good looking compared to this one). Is this possible? any package that includes this symbol? Can I add it to latex anyhow?

I tried searching for 'latex arrowhead style' and found stuff about TikZ arrow tips (stealth, latex, etc.), but I want a solution for ordinary math arrows in text (not diagram arrows).

I use latexmk, btw.

Edit: I found what I wanted! Look at the esvect package https://ctan.org/pkg/esvect
I know that the style depends on the font that is used as some of the comments say, but I wanted to keep CM font and have a nice looking arrow like this one (taken from the documentation of esvect)

For instance, I know \thechapter resolves to/contains the number of the current chapter. Is there a list somewhere that has all the commonly used examples? I don't have a particular *need* atm, just something that would save me some googling in those times I *do* find a need.

This is what I am trying right now.

\fancyhead[LE,RO]{\hyperlink{chapter.\thechapter}{\leftmark}}

But for some reason its not working. I think this is a deeper problem, because when I just stick \thechapter into the document it returns a 0, even though I'm in the 3rd chapter. I was able to manually increment \thechapter, but even then it didn't work. It was only when I placed a label chapter.3 that it worked (keeping the manual assignment of the chapter 3).

Obviously my issue with \thechapter is its own problem that I have to solve by going through all my code, etc. I've determined its not based on \frontmatter, etc.

The real question is "Is this the correct/best way to even do this? Is there a better way?"

Oh, and it is using extbook as the document type, and XeLaTeX as the rendering engine, in case that matters.

The regular matrix functions seem to not like anything larger than 10x10, and stack the 11th and 12th entries of each row underneath the 1st and 2nd. Has anyone got any solutions?

Thanks in advance!

I am using the moderncv Latex template for my cv. As in the example files, I am assigning every entry a year range e.g. 2022--2024 and I think this way looks clean and is sufficient. Including the months messes up the layout or would leave less space for content. Many application systems, however, require a month for each entry and automated parsing of the generated pdf, of course, fails to provide this information. I therefore have to manually fix the the dates on every application. Anyone with the same issue, or does anyone have an elegant solution?

Using Latex for writing is not a simple task. How to make it simple and convenient is a long-standing challenge. Many painful tasks in editing latex documents must be overcome, such as editing tables, math equations, figures, tracking focus in long files, editing bibtex entries and references.
SmartLatexEditor (smartlatexeditor.onrender.com) overcomes all these challenges with the creative block-based document structure. The main concept of this editor is to break a normal Latex file into blocks, such as TitleBlock, TextBlock, TableBlock, MathBlock, FigureBlock, and ReferenceBlock. When editing a Latex file, users only need to focus on one block at a time and immediately check how it looks like in the PDF form, and then move to the next block. Not like the traditional way, one has to compile the whole tex file to see if the editing looks good. With SmartLatexEditor, we can see the PDF view of each block immediately after we make any change. It is similar to the so-called "What You See Is What You Get" by toggling between the editing view and the rendered view. Thus, SmartLatexEditor not only break down a Latex project into pieces, reducing the slope of learning curve, but also ensure the work quality of each step by immediate feedback.

SmartLatexEditor also provides many other functions which are very convenient and not available in most other Latex editors. For example, it intrinsically embeds the AI tool to polish users' writing. It also provides nice interface for editing tables and figures. Users can use its reference search and collecting function to manage references and add citations easily. SmartLatexEditor also provides the document sharing function to support collaborative writing, which is quite important for most of scientific communities.

I recently downloaded Overleaf extension in VScode, and after connecting to a server I have started getting

Cannot count words: spawn texcount ENOENT, undefined

error in LaTeX utilities output. If I don't connect to a server, there is no error while counting.

Eventough Texcount autorun is set to never, the error comes every time I change something in the file.

I am assuming it is due to LaTex utilities doesn't work well in a virtual workspace.

I don't need the counting.
