Hi, can you share the full output log? |

Here's the output from the "Vala Language Server" drop-down in "output" tab. (Note that the errors here are consistent with the errors that I should be getting inline.) Output: Vala Language ServerAnd here's the output from a few other drop-down items under "output". (Note that this is on a macOS host device.) Output: Log (Extension Host)Output: Log (Remote Server)Output: Log (Remote Extension Host)And here's the output from Command Line Build Outputroot@a08fa01d3aae:/workspaces/nextcloud-vala# ninja -C Build

ninja: build stopped: subcommand failed.Colin has since told me that when he reproduced the issue in Sublime Text, he did so not in a Docker container but rather on a regular elementary OS device. Nonetheless, here are some other possible causes:
Please do let me know if there's anything else you need. Thanks! |
|
@elsiehupp you need to enable debug mode. You would get much more informative output, then. To do this, go into the extension settings and enable "Debug Mode." Then rerun VLS and give me the log. |
|
I will say it looks from your build log that your project can't compile, which could be the root cause, but we'll have to see what the log says. |
|
Hi @Prince781—thanky you for your response!
I ran into an issue with Meson not properly cloning a
Anyway, with the Meson changes and with debug enabled on the Vala extension—see this commit I just pushed—the output is as follows: Output: Vala Language ServerThe other logs are as follows: Output: Log (Remote Server)Output: Log (Remote Extension Host)And Command Line Build Output |
|
The problem here is that you're using a version of VLS that's over a year old: This might be fixed in the latest stable release, which is the only version of VLS that we support. What you can do is have your container build and install VLS 0.48.5, then see if you still have this issue. |

Okay! So I removed the elementary OS version of
Here is the same set of outputs after I switched to OutputOutput: Vala Language ServerOutput: Log (Remote Server)Output: Log (Remote Extension Host)Command Line Build Output |

The root cause here may be that because at least one of your subprojects fails to build, the main project might be without a |
|
However, if you said this only fails inside a container, that's even stranger... |
@colinkiama was apparently able to reproduce the issue outside the sandbox (also on elementary OS). He talked about it on the Vala Discord but hasn't had a chance to drop by this issue thread, yet. Way back in my original comment, I did say this:
Basically I did the switch to Meson subprojects at roughly the same time that I did the switch to a Docker container, which made it difficult to tell which of the two was the likely culprit. Oops!
I mean, the odd (or frustrating) thing here is that code intelligence just silently fails, without
I guess the issue then is that there's an error in the build process that causes code intelligence to fail to launch, but neither

elsiehupp
changed the title
|
I changed the title because the issue doesn't seem to be specific to the container. I did comment out literally everything except the class names, so that compilation would work (though with no actual code), and code intelligence started working again, so the container doesn't seem to be the problem. I'll follow up if I have any further information down the line. |
|
Personally mine is failing to start when I add dependencies other then the one provided by the GNOME Builder template for Vala applications. Here's a snippet of my meson.build. The libsoup-3.0 is the dependencies troubling the language server for me. edit: I was just dumb and installed the wrong dev package on my system. It works fine now. |

Describe the Bug
I'm having trouble with getting
vala-language-serverto do VS Code code intelligence in a Docker Dev Container (based on the elementary OS Odin Dockerfile; customized version here). Vala Language Server does show up in the drop-down menu under "Output", but none of the output appears with inline code intelligence (i.e. under "Problems").I was, in fact, able to use Vala Language Server VS Code code intelligence in a regular elementary OS setup, but I haven't gotten it to work since I set up a Docker Dev Container. There is also a non-zero possibility that the issue doesn't actually have anything to do with the Dev Container but rather arose from other changes I made around the same time, but it's difficult to test this hypothesis either way.
I should also mention that, yes, both
vala-language-serverand theprince781.valaVS Code extension are installed and set up in the Dev Container: I do have syntax highlighting and output, just not inline code intelligence, so it seems like the two maybe just can't see or talk to each other? The container settings do manually specify the install path, though.Software
