File IO

Line by Line

Get-Content is bad practice when the file is larger enough to process line by line, the memory might overflow during runtime. Using .NET class such as FileStream can be just fine but a little complicated. The most direct solution is using switch -File statement. A switch statement with -File flag enumerates the whole file line by line, each line was matched with given pattern, and such pattern can combine with other flags such as -CaseSensitive. You may use break to terminate the whole loop or continue to skip to next iteration.

switch -CaseSensitive -Wildcard -File ~/.local/state/nvim/lsp.log {
    'fsautocomplete' {
        if ($shouldSkip) { continue }
        $_ # current line
    }
    'ERROR' {
        break; # the whole switch is terminated
    }
    default {
    }
}

NOTE

There should not exist brackets around file name in switch -File <filename>
