Crash on a custom syntax file with a Swift shebang #3450
Description
Description of the problem or steps to reproduce
Preamble
The Micro has syntax support for Swift language, but only when filenames end with the .swift extension. Unfortunately, it doesn't recognize a shebang #!/usr/bin/swift and no syntax highlighting as the result. The shebang is totally valid on macOS, as that's the official Swift interpreter.
Problem
I decided to create a custom syntax file ~/.config/micro/syntax/swift.yaml with the following content:
filetype: swift
detect:
header: "#!/usr/bin/swift"Now, whenever I create a new file, add a shebang #!/usr/bin/swift, and then save it, the editor crashes every time with the following output:
Micro encountered an error: runtime.errorString runtime error: invalid memory address or nil pointer dereference

If I open an already existing file with the same shebang, I get a crash with the following output:
