I needed a way in vim config to use counters and what better way, but to write a function to simultaneously handle all variables and optinally increase or decrease them:
" define and manage counters " NB! all counters are namespaced globally (g:) function! Counter(name,...) " check if this variable already exists or should we initialise it if !exists("g:" . a:name) exec 'let g:' . a:name .' = 0' endif " if second parameter is given, increase/decrease value if a:0 > 0 exec 'let g:'. a:name .' = g:' . a:name . ' + ' . a:1 endif exec 'return g:' . a:name endfunction
Usage of the function is as follows:
" Get the current value echo Counter('mycount') " Increase value by 1(and return the new value) echo Counter('mycount', 1) " Decrease value by 2 echo Counter('mycount', -2)
