Silently call a mapping that accepts a range

I have the following function that I'm calling to insert blank lines under the cursor:

function InsertBlankLine() call LogOutput('*** START ***', "DEBUG", {'line': expand('<sflnum>'), 'func': expand('<sfile>')[9:]}) " a: args will give us the following by default: -- see `:h: a:var` " '0': '000': 'firstline': 109, 'lastline': 108 " '0' is the number of extra arguments, '000' is the list of those extra args let data = a: call LogOutput("Data: " . string(data), "DEBUG", {'line': expand('<sflnum>'), 'func': expand('<sfile>')[9:]}) " Access a dict value get(dict, 'value') let first_line = get(a:, 'firstline') " Insert a new line call LogOutput('Executing normal o', "DEBUG", {'line': expand('<sflnum>'), 'func': expand('<sfile>')[9:]}) execute "normal! o" " Go back to the first line let cmd = printf("normal! %sG", first_line) call LogOutput('Executing cmd: ' . cmd, "DEBUG", {'line': expand('<sflnum>'), 'func': expand('<sfile>')[9:]}) execute cmd endfunction 

And I can call it like this with a shortcut:

nnoremap T :call InsertBlankLine()<CR> 

So that I can type in 10T and it will insert ten blank lines. This all works. However, it spits out a lot of input which I want to suppress using silent. However, I'm not sure how to pass :silent to the function as it will usually start with a number. For example, if I type in 10T, this is the command it runs:

:.,.+9call InsertBlankLine() 

So how would I get that to execute silently (without removing the LogOutput's ?
