I'm trying to make a function to insert license header from external file on first line in the buffer. The script is:
fun InsertLicense()
if filereadable('LICENSE')
let license = 'LICENSE'
elseif filereadable('LICENSE.txt')
let license = 'LICENSE.txt'
else
let license = ''
endif
if line('$') < 3 && len(license) > 0
echo 'inserting license from ' . license
call append(0, readfile(license))
endif
endfun
It's working fine except one problem: LICENSE file is a plaintext file, e.g.:
Copyright 2019 OrgName
Permission is hereby granted, free of charge, to any person
obtaining a copy of this software and associated
...
but I need to wrap it as Java multiline comment:
/*
* Copyright 2019 OrgName
*
* Permission is hereby granted, free of charge, to any person
* obtaining a copy of this software and associated
...
*/
Is it possible to insert * before each line of license file using vim scripting language?

readfile() returns a list, each line being in a separate list item.
You can therefore make use of map() to change the list inplace:
let a=map(readfile('LICENSE'), i,v -> '/* ' . v. ' */')
This makes use of lambda expression and wraps a the comment characters /* and */ around it.
Alternatively, you can do this:
:let a=['/* '] + map(readfile('LICENSE'), i,v -> '* ' . v) + ['*/']
which adds only /* at the start of the file and */ at the end of the file and for each line simply prepends the *.
