# Rosenrot # Rosenrot
Rosenrot is a small browser forked from an earlier version of [rose](https://github.com/mini-rose/rose). It has some additional quality of life improvements tailored to my (@NunoSempere) tastes and setup, and detailed installation instructions for Debian 12. This branch contains a minimalist version of rosenrot, similar in many ways to the original version of rose.

![](https://raw.githubusercontent.com/NunoSempere/rosenrot-browser/master/images/6-multiple-tabs.png)
### Installation and usage
You can see detailed instructions [here](./user-scripts/debian-12/install-with-dependencies.sh), for Debian 12 in particular—though they should generalize easily to other distributions.
The general steps are to install dependencies, and then
```
make build
make install # or sudo make install
rose
```
You can also collect some profiling info, and then use that to get a perhaps faster version:
```
make fast ## will ask you to use the browser for a bit
make install
rose
```
You can also create a rose.desktop file so that it will show up in your desktop environment. You can see this documented [here](./user-scripts/debian-12/install-with-dependencies.sh).
## Features
- Tabs, cookies, caching
- Minimal ui, autohiding elements
- ~454L core code (the rose.c file)
- Customize appearance of the browser through css
- Built-in rose-mklink script for in-shell static links
- Optional adblocking through [wyebadblock](https://github.com/jun7/wyebadblock)
- Plugin system, seeded with:
- Libre redirect: Redirect annoying websites to open source frontends
- Readability: Strip webpages of unnecessary elements for ease of reading with a custom shortcut
- Custom style: Override the css of predetermined websites
- Max number of tabs (by default 8), configurable.
- Stand in plugin: Mimick function definitions which do nothing for the above plugins so that they can be quickly removed
You can see some screenshots in the [images](./images) folder.
## Similar projects
Here are some similar projects that I could find (minimalist, mostly based on webkit):
- [Surf](https://git.suckless.org/surf/). Suckless community. Similar goals, higher coding standards, less actively maintained.
- [Rose](https://github.com/mini-rose/rose-browser). Lua integrations, supports compilation with GTK4. Every now and then, the developer nukes the git history and tries some different approach.
- [Epiphany](https://gitlab.gnome.org/GNOME/epiphany). GNOME. Clean browser, distributed via flathub, aimed at nontechnical users. Seems actively maintained.
- [Vimb](https://github.com/fanglingsu/vimb). Reasonably actively maintained, vim keybindings.
- [Nyxt](https://github.com/atlas-engineer/nyxt). Emphasis on sophisticated key bindings.
- [Wyeb](https://github.com/jun7/wyeb)
- [Luakit](https://github.com/luakit/luakit)
- ~~[Qutebrowser](https://github.com/qutebrowser/qutebrowser). More actively maintained. I don't understand the tech stack.~~ [Based](https://github.com/qutebrowser/qutebrowser/blob/main/doc/faq.asciidoc) on [Chromium](https://wiki.qt.io/QtWebEngine)
Here are other projects I haven't checked out as much: [netsurf](https://www.netsurf-browser.org/), [uzbl](https://www.uzbl.org/), [edbrowse](https://github.com/CMB/edbrowse),
Here are projects with their own rendering engines which could appeal to users of rosenrot:
- [lynx](https://lynx.invisible-island.net/) (links, elinks), [w3m](https://w3m.sourceforge.net/): command line browsers.
- [dillo](https://github.com/dillo-browser/dillo/). Has its own rendering engine, and no javascript.
- [Ladybird](https://github.com/SerenityOS/serenity/tree/master/Ladybird). SerenityOS. Uses its own html and javascript engine. Compiling it on a mainstream Linux distribution, and documenting instructions could be an interesting project, but the few times I've tried that I've failed.
- [servo](https://github.com/servo/servo). Firefox/Mozilla. An in-development browser engine written in Rust, meant to replace Gecko. Could be extremely cool once it is ready, but it has been many years in development.
### Relationship with [rose](https://github.com/mini-rose/rose)
- Rose is a small browser based on webkit2gtk. Previously, it described itself as aiming to be a "basement for creating your own browser using [the] gtk and webkit libraries". It has since diverged into a more featureful small browser with lua bindings, and rebased its history. You can see the original, minimal version [here](https://github.com/NunoSempere/rosenrot-browser/blob/a45d1c70f58586fed97df70650e5d066b73d0a0d/rose.c).
- The current version offers compilation with both GTK3 and GTK4, and an up to date version of webkit.
- Rosenrot is my (@NunoSempere's) fork from that earlier minimal rose. It has accumulated quality of life features and, honestly, cruft, that I like, like a "readability" plugin that simplifies annoying websites like [Matt Levine's Money Stuff newsletter](https://www.bloomberg.com/opinion/articles/2022-10-18/matt-levine-s-money-stuff-credit-suisse-was-a-reverse-meme-stock). It also incorporates ad-blocking.
- Rosenrot is also a song by the German hardcore rock band [Rammstein](https://www.youtube.com/watch?v=af59U2BRRAU).
### Comparison with [surf](https://git.suckless.org/surf/file/surf.c.html)
- Surf is another browser based on GTK/Webkit, from the suckless community.
- It is significantly more complex: surf.c has [2170](https://git.suckless.org/surf/file/surf.c.html) lines, vs rose.c's [454](https://git.nunosempere.com/open.source/rosenrot/src/branch/master/rose.c).
- I find its code messier and harder to understand.
- Conversely, surf has significantly more configuration options, and digs deeper into webkit internals.
- Anecdotically, surf feels slower, though I haven't tested this rigorously.
- surf has a larger community, with patches and modifications.
- surf is more opinionated, but also less amateurish.
- Like rosenrot until very recently, it [uses](https://git.suckless.org/surf/file/config.mk.html#l15) an obsolete & deprecated version of [webkit](https://blogs.gnome.org/mcatanzaro/2023/03/21/webkitgtk-api-for-gtk-4-is-now-stable/)
- My recommendation would be to use rosenrot, and if you find some feature missing, either look how surf does it and import it to rose, or move to surf.
- But then again, I've built rosenrot to cater to my own tastes, so I'd say that.
## Folk wisdom
Of general interest:
- I just found out that you can inspect a GTK application with the GTK explorer if you set a certain command-line variable. Try this with `make inspect`.
- Static variables keep their value between invocations.
- By default the searchbar is pretty gigantic. I've made this so because I'm a bit myopic, but also work with my laptop in a laptop stand. Anyways, if you are a more normal person you can change this in the style.css.
- The style.css usage isn't updated until installation. This is because by default rose uses the theme located in /usr/share/themes/rose/style.css, and that file isn't updated until make install.
The "architecture" of the application looks as follows:
![](https://raw.githubusercontent.com/NunoSempere/rosenrot-browser/master/images/0-architecture.png)
## webkit2gtk-4.0 vs webkit2gtk-4.1 vs webkit2gtk-6.0
See [this blog post](https://blogs.gnome.org/mcatanzaro/2023/03/21/webkitgtk-api-for-gtk-4-is-now-stable/) for details. webkit2gtk-4.0 is deprecated, webkit2gtk-4.1 is the current [stable](https://webkitgtk.org/reference/webkit2gtk/stable/index.html) release and uses GTK3. webkit2gtk-6.0 is the current [unstable](https://webkitgtk.org/reference/webkitgtk/unstable/index.html) release, and uses GTK4.
Migration instructions for migration to webkit2gtk-6 and GTK4 can be seen [here](https://github.com/WebKit/WebKit/blob/ed1422596dce5ff012e64a38faf402ac1674fc7e/Source/WebKit/gtk/migrating-to-webkitgtk-6.0.md) and [here](https://docs.gtk.org/gtk4/migrating-3to4.html).
Rosenrot is currently on the stable webkit2gtk-4.1 release using GTK3, and has removed deprecated webkit apis. It has plans to eventually migrate to webkit2gtk-6.0 eventually but not soon, because the GTK4 rewrite seems onerous.
## Ubuntu 20.04
A previous version of this repository was based on Ubuntu 20.04. You can still see documentation for that distribution [here](https://git.nunosempere.com/open.source/rosenrot/src/commit/8a1e0be30df52d5a21109297fd5bbc20efec1b3b), particularly a video installing rosenrot in a fresh Ubuntu 20.04 virtual machine [here](https://video.nunosempere.com/w/t3oAvJLPHTSAMViQ6zbwTV). However, that uses the webkit2gtk-4.0 library. Instead, I recommend adapting the Debian 12 instructions.

# To do # To do
- [ ] Settle on a C standard (C11?), and use safer string handling functions provided by it. - [ ] Create minimalist version of rosenrot
- See make lint for purported insecurities
- [ ] Document creating new applications, e.g., as in [Asana for Linux](https://git.nunosempere.com/NunoSempere/asana-for-linux)
- [ ] This time, use something other than Whatsapp as an example syslink.
- [ ] Fix bug about distorted audio. Maybe related to [this pipewire issue](<https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1547>)?
- See whether it even exists at all
- [ ] Upgrade to GTK-4 / Webkitgtk 6.0? Will take a fair amount of time, since GTK4 redesigns the application model somewhat.
- Instructions for webkit-6.0 [here](https://github.com/WebKit/WebKit/blob/ed1422596dce5ff012e64a38faf402ac1674fc7e/Source/WebKit/gtk/migrating-to-webkitgtk-6.0.md)
- Instructions for GTK-4 [here](https://docs.gtk.org/gtk4/migrating-3to4.html)
- [ ] Prepare for GTK-3 to GTK-4 transition
- [ ] Understand wtf is going on with signals and events: <https://docs.gtk.org/gtk4/migrating-3to4.html#stop-using-gtkwidget-event-signals>. <https://github.com/mini-rose/rose-browser/blob/288bf060d095c4895946669ae50d14193168b69c/src/window.c#L42>

- ~~[ ] Set [`webkit_web_context_set_sandbox_enabled`](<https://webkitgtk.org/reference/webkit2gtk/2.36.8/WebKitWebContext.html#webkit-web-context-set-sandbox-enabled>), as recommended [here](<https://blogs.gnome.org/mcatanzaro/2022/11/04/stop-using-qtwebkit/>)~~. Irrelevant with upgrade to libsoup3.
- [x] Update to webkit2gtk-4.1
- [x] Change README and point to last Ubuntu 20.04 commit
- [x] Add list of similar projects: <https://github.com/qutebrowser/qutebrowser#similar-projects>
- [x] Add comparisons against rose & surf
- [x] Compare against rose
- [x] Compare against surf
- [x] ~~Doesn't work with when Spanish is selected as the language, for some reason~~ => Previously misdiagnosed. The real issue was that it freezes when interacting with [Espanso](https://espanso.org/) substitutions, which I had set-up automatically on my machine when using words containing an ñ, like my own name, Nuño.
- [x] Add css for js alerts
- [x] Add custom alert whose css can be customized
- [ ] ~~Debug problems, e.g., this version is non-blocking.~~ => will leave as is
- [x] Figure out better way to have plugins => stand_in code seems superfluous
- [x] Double check newtab/next-tab behavior => custom style now loading correctly.
- [x] Add a shortcut for hiding the search tab. => Already exists: Ctrl+K
- [x] Find out what each of the css elements refers to. => done, see make inspect
- [x] Figure out if downloading files is doable. => it is
- [x] Look at using relative rather than absolute paths for configuration. => now makefile is a bit smarter
- [x] Streamline installation a bit
- [x] Substitute paths in makefile
- [x] Create cache directory automatically
- [x] Add an installation video walkthrough. Done, [here](https://video.nunosempere.com/w/t3oAvJLPHTSAMViQ6zbwTV)
- [x] Document `stand_in.c` better
- [x] Use a makefile.
- [x] Add clean, uninstall to makefile
- [x] Mask user agent
- [x] Launch with more than one tab from command line
- [x] Figure out merge with upstream
- [x] String substitution on uri in order to redirect to better frontends.
- [x] Present "standard" browser keybindings as an alternative.
- [x] Fix zoom in new tab
- [x] Reader mode
- [x] Add reader mode to config.def.
- [x] Make tab bar slightly prettier.
- [x] Add "open in new window" functionality.
- Useful for opening links in new tab when clicking on them and selecting that option
- And for actually opening links with the href new_tab option.

In case you arrive at a segmentation fault when working on rose, you can use valgrind.
To do this, you can compile rose with the `DEBUG` value in `build.sh` set to `-g`
and then:
```
valgrind --track-origins=yes ./rose
```
