It has some additional quality of life improvements tailored to my (@NunoSempere) tastes and setup, and detailed installation instructions for Debian 12. - - - - - - - -### 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: - - - -## 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. - +This branch contains a minimalist version of rosenrot, similar in many ways to the original version of rose. @@ -1,57 +1,3 @@ # To do -- [ ] Settle on a C standard (C11?), and use safer string handling functions provided by it. - - 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.
