empty m_EditorVersion

Error message

empty m_EditorVersion

What it means

The unity segment reads ProjectSettings/ProjectVersion.txt to report the Unity editor version. GetUnityVersion parses lines looking for the m_EditorVersion prefix; if the prefixed line exists but the remainder is empty after trimming, it throws 'empty m_EditorVersion'. The file exists and has the key but no value.

Solutions

1. Open the project in Unity (or run it) so ProjectVersion.txt is rewritten correctly
2. Restore ProjectVersion.txt from version control (git checkout -- ProjectSettings/ProjectVersion.txt)
3. Manually set the value, e.g. `m_EditorVersion: 2022.3.10f1`
4. Disable the unity segment when not inside a valid Unity project

Example fix

// before: ProjectSettings/ProjectVersion.txt
m_EditorVersion:
// after
m_EditorVersion: 2022.3.10f1

// before parsing, validate the file content
data, err := os.ReadFile("ProjectSettings/ProjectVersion.txt")
valid := err == nil && strings.TrimSpace(strings.TrimPrefix(strings.TrimSpace(string(data)), "m_EditorVersion:")) != ""

When it happens

Trigger: Enabled calls GetUnityVersion while in a Unity project directory and ProjectSettings/ProjectVersion.txt contains a line starting with `m_EditorVersion:` (or the configured prefix) whose value is empty or only whitespace — typically a truncated or interrupted project serialization.

Common situations: Unity crashed or was killed mid-write leaving an incomplete ProjectVersion.txt; the file was hand-edited or diff-merged badly; a git LFS checkout produced an empty value; working in a partially initialized project folder.
