Support for code generation from command line

[EricBourdin]

Hi It would be useful to add support for C code génération from command line. It would allow projects with eez studio to integrate nicely in Continous integration systems (Aka Jenkins).

My personal need is for lvgl projects.

You can now start EEZ Studio executable from command line with --build-project parameter. For example:

eezstudio --build-project /path/to/my-project.eez-project

This feature will be available in the next version, 0.13.0, which will be released in about 4 weeks.

Another way is to clone studio repository right now and then:

npm install
npm run build
npm start -- --build-project /path/to/my-project.eez-project

I'm not sure how this is practical for your Continuous integration system since building studio from source takes some time which will add to your total building time.

Another way this could be done is to migrate the complete LVGL build support to another repository and make npm module out of it. But it's too much work for us right now.

Maybe publish a docker container with each release in the future? That might allow for faster CI runs on git

Good idea. Is there anyone here who can help with this?

Hello, I have tried this feature with latest version of EEZ Studio (0.13.0) The feature works. Thank you very much for implementing it.

But unfortunately when running from our Continuous Integration server, we encounter a problem related to $DISPLAY environment variable.

We have this error message: [48268:0516/140019.030212:ERROR:ozone_platform_x11.cc(240)] Missing X server or $DISPLAY

To reproduce this, you can use this steps on Linux:

$ unset DISPLAY $ eezstudio --build-project lvgl_user_widget_example.eez-project [48268:0516/140019.030212:ERROR:ozone_platform_x11.cc(240)] Missing X server or $DISPLAY [48268:0516/140019.030253:ERROR:env.cc(257)] The platform failed to initialize. Exiting.

Do you think it is possible to fix this ?

Although this feature does not require a GUI, EEZ Studio is a GUI application and requires GUI support on the system (DISPLAY environment variable and X server). I see that there are a lot of questions on the Internet about how to run Chromium in combination with Selenium under one of the CI systems, so I suggest that you try to find a solution yourself and please report the result here.

I am using this : xvfb-run eezstudio

Xvfb is a tool to run X11 app without X11.

Is it working with the xvfb-run?
