Whenever looking at one these, I think back to the obscure but interesting "tup": “How is it so awesome? In a typical build system, the dependency arrows go down. Although this is the way they would naturally go due to gravity, it is unfortunately also where the enemy's gate is. This makes it very inefficient and unfriendly. In tup, the arrows go up.” https://gittup.org/tup/. - Source: Hacker News / 4 months ago

Once upon a time, you could roll your own of this using `tup` which might have my favorite "how it works" in the readme: How is it so awesome? In a typical build system, the dependency arrows go down. Although this is the way they would naturally go due to gravity, it is unfortunately also where the enemy's gate is. This makes it very inefficient and unfriendly. In tup, the arrows go up. This is... - Source: Hacker News / 6 months ago

Ten years ago, I used reStructuredText and its support for LaTeX math and syntax highlighting. I used tup (tup monitor -a -f) to take care of running rst2html on save. Source: 12 months ago

The dependency resolution is core to https://gittup.org/tup/ which had been adopted a bit at the time it came out but since faded back into obscurity. - Source: Hacker News / about 1 year ago

I might be showing my ignorance here, but this just sounds like Tup? https://gittup.org/tup/. Source: about 1 year ago

Please note that the original app was Xournal [1]. The one you link is a rewrite of the orignal (in C++) and is called Xournal++. [1] https://xournal.sourceforge.net/. - Source: Hacker News / 3 months ago

I do the using Xournal [1] which is tailor-made for creating annotations. It leaves the PDF as is, saving your edits to a sidecar file (*.xoj) which when loaded pulls in the original PDF. It exports edited documents to 'real' PDFs with selectable text etc. [1] https://xournal.sourceforge.net/ (packaged by most distributions). - Source: Hacker News / over 1 year ago

If you don't mind the signature being raster (not vector), I've used Xournal for this in the past. It's extremely lightweight and easy. Just open the PDF file with Xournal, draw the signature, and then export it to PDF (Control + E). This will not rasterise the PDF itself (to the best of my knowledge), but rather just superimposes a layer containing your signature on top of the original PDF. Source: about 2 years ago

Xournal++ exists since 2013. Maybe you typoed and by your comment about abandoning you were referring to Xournal without the ++? The Xournal website even suggests to try Xournal++. Source: over 2 years ago

Xournal works pretty well for me on GNU/Linux. You just have to turn on the "Legacy PDF Export" option. Source: almost 3 years ago
