unclosed section:

Error message

unclosed section: 

What it means

The ini parser treats a line starting with '[' as a section header and requires a closing ']'. strings.CutLast fails to find ']' so the line is malformed. The error echoes the offending line so you can spot the typo in the loaded config.

Solutions

1. Open the config file and add the missing ']' to the reported line, e.g. '[section]'
2. Escape or comment out the stray bracket line if it isn't meant to be a section
3. Validate the file with a TOML/INI linter before loading

Example fix

// before (file content)
[segment
// after (file content)
[segment]

for i, line := range lines {
    if strings.HasPrefix(strings.TrimSpace(line), "[") && !strings.Contains(line, "]") {
        return fmt.Errorf("line %d: unclosed section header", i+1)
    }
}

func isClosedSectionLine(line string) bool {
    return !strings.HasPrefix(line, "[") || strings.Contains(line, "]")
}

file, err := ini.Load(path)
if err != nil {
    if strings.Contains(err.Error(), "unclosed section") {
        return fmt.Errorf("config %s malformed: %w", path, err)
    }
    return err
}

When it happens

Trigger: parse() (via Load or LoadVerbatim) encounters a line whose first byte is '[' but has no ']' anywhere in it - e.g. '[section' or a stray bracket line like '[TODO fix this'.

Common situations: Hand-edited oh-my-posh theme/config files with a truncated section header; copy-paste losing the closing bracket; a comment line accidentally starting with '['.
