 # Building
-## Via flatpak (recommended)
+## Via flatpak
-The recommended way to build is using flatpak, which will take care of all dependencies and avoid any problems that may come from different system configurations.
+If you don't have the flathub repo in your remote-list for flatpak you will need to add that first:
 First, install the required flatpak platform and SDK, if you dont have them already:
 ```shell
-$ flatpak install org.gnome.{Platform,Sdk}//40 org.freedesktop.Sdk.Extension.rust-stable//20.08
+$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
 ```
-To compile and install as a flatpak, run
+Then install the required flatpak platform and SDK, if you dont have them already:
 ```shell
-$ flatpak-builder --install flatpak-build/ org.freedesktop.ryuukyu.Helvum.json
+$ flatpak install org.gnome.{Platform,Sdk}//41 org.freedesktop.Sdk.Extension.rust-stable//21.08 org.freedesktop.Sdk.Extension.llvm12//21.08
 ```
 To compile and install as a flatpak, clone the project, change to the project directory, and run:
 ```shell
 $ flatpak-builder --install flatpak-build/ build-aux/org.pipewire.Helvum.json
 ```
 You can then run the app via
 ```shell
-flatpak run org.freedesktop.ryuukyu.Helvum
+$ flatpak run org.pipewire.Helvum
 ```
 ## Manually
 For compilation, you will need:
 - Meson
 - An up-to-date rust toolchain
 - `libclang-3.7` or higher
 - `gtk-4.0` and `pipewire-0.3` development headers
-To compile, run
+To compile and install, run
-    $ cargo build --release
+```shell
 $ meson setup build && cd build
 $ meson compile
 $ meson install
 ```
 in the repository root.
-The resulting binary will be at `target/release/helvum`.
+This will install the compiled project files into `/usr/local`.

            Helvum is a graphical patchbay for PipeWire.
            It allows creating and removing connections between applications and/or devices to reroute
            flow of audio, video and MIDI data to where it is needed.

 # Making a release
 The following describes the process of making a new release:
 1. In `data/org.pipewire.Helvum.metainfo.xml.in`,
   add a new `<release>` tag to the releases section with the appropriate version and date.
 2. In `meson.build` and `Cargo.toml`, bumb the projects version to the new version.
 3. Ensure cargo dependencies are up-to-date by running `cargo outdated` (may require running `cargo install cargo-outdated`) and updating outdated dependencies (including the versions specified in `Cargo.lock`).
 4. Commit the changes with the a message of the format "Release x.y.z"
 5. Add a tag to the release with the new version and a description from describing the changes as a message (run `git tag -a x.y.z`, then write the message)
 6. Make a **new** meson build directory and run `meson dist`.
   Two files should be created in a `meson-dist` subdirectory:
   `helvum-x.y.z.tar.xz` and 
   `helvum-x.y.z.tar.xz.sha256sum`
 7. Push the new commit and tag to upstream, then create a new release on gitlab from the new tag, the description from the tags message formatted as markdown, and also add the two files from step 6 to the description.

Tom A. Wagner	c887d77f64	graphview: Use #808080 as link color For good contrast in both dark and light mode, the link color is now a semi-light gray instead of complete black, which had bad contrast in dark mode and good constrast in light mode. Later, we can seperate color palettes for light and dark mode, but only together with a dark mode toggle button or system-wide darkmode toggle.	2021-11-13 20:32:40 +01:00
Tom A. Wagner	54d7ca83ae	graphview: Define link and grid colors in style.css Previously, these were defined directly in the code, but defining them in the css helps seperating theming and behaviour and makes the colors easier to tweak.	2021-11-13 20:08:47 +01:00
Tom A. Wagner	7b1b5ea336	build: fix and improve cargo.sh cargo.sh previously used bash features but only used `sh` in the shebang, and also did not properly quote some variables to avoid splitting/globbing from happening. Also, `-euo pilefail` is now set to avoid other errors that might come up.	2021-10-26 10:04:07 +02:00

Tom A. Wagner	dfb1b754c7	Add and install icons. This adds one new app icon and one new symbolic icon, and makes meson install these to the appropriate directories, and adds an appropriate entry in the .desktop file.	2021-09-30 08:28:06 +02:00
Tom A. Wagner	497da8b953	graphview: Do not crash when the position of a node not on the graph is requested While the position of a node not on the graph should never be requested, this seems to occur sometimes, so instead of panicking, we only log an error now, or ignore that node if it wasn't important.	2021-09-11 15:03:03 +02:00
Tom A. Wagner	da5da90352	Add .desktop file This adds a .desktop file (without icon for now), which will automatically be installed when `meson install` is run.	2021-08-29 18:41:09 +02:00
Tom A. Wagner	a8bfd8383e	buildsystem: Move to meson for building the project Meson will allow us to: - Verify the used rust compiler is recent enough - Install ressources such as a .desktop files, icons, etc.	2021-08-29 17:28:55 +02:00
