Re: [Gnuplot-info] remove extension

[ivana r. <iva...@mf...>]

Hi Patrick,

if you don't wanna to call system commands, see "String functions"
manual section:

-- if you are sure to have the 3-letters extension than you can simply write

> myvar=filename[1:strlen(filename)-4]

-- if you are satisfied with the filename shortage to the first dot if
exists than you can simply write

> myvar=filename[1:strstrt(filename, ".") - 1]

-- if you wanna be sure to remove just the last dot if exists than you can write

> f(n,a)=(_n=n, _a=strlen(a), _f=strstrt(a[_a-_n:_a], "."), _f||(_a==_n)?a[1:_a-_n-1]:f(_n+1,a))
> myvar=f(0,filename)

Sincerely

Iva
