Seamly2D ci
The Seamly2D project began, using the original tools that had been used used for CI in support of the Valentina project. These included appveyor, travis, launchpad, and bintray.
Appveyor was used to create the windows executables for testing and release. Travis was used to create release and testing executables for the Mac operating system. The windows and Mac versions of the software were made available by providing the user with a URL to find the file which they could then download and install. The files were stored on a publicly available location hosted by bintray. Because of the differences in the way software is packaged and delivered in Ubuntu, launchpad was used to release software for Ubuntu. The Ubuntu version of Seamly2D software was released to launchpad into two different PPAs. https://www.makeuseof.com/tag/ubuntu-ppa-technology-explained/
The release version of the Ubuntu Seamly2D software was stored in a repository named susan-spencer/seamly2d. Only official release versions are pushed to the seamly2d PPA. It is described on launchpad as follows:
Open source pattern making software. GPLv3
Add this software to your system:
sudo add-apt-repository ppa:susan-spencer/seamly2d
sudo apt-get update
sudo apt-get install seamly2d
Changes are pushed regularly to the development version of the repository, where users were encouraged to take a chance and test the newest features with the understanding that there could be some software "bugs". Presumably, the users who choose the seamly2d-dayly-build repository are knowledgeable and chose to tolerate some software bugs in return for using the newest features more quickly. The repository is described on launchpad as follows:
Open source pattern making software. GPLv3
You can update your system with unsupported packages from this untrusted PPA by adding ppa:susan-spencer/seamly2d-dayly-build to your system's Software Sources. (Read about installing)
sudo add-apt-repository ppa:susan-spencer/seamly2d-dayly-build
sudo apt-get update
