Avisynth for loop GScript

[wiseant]

Hi

I am trying to use GScript to create a for loop

I have an avsi file that list 34 fonts, i.e.
f1 = "ARIAL" ... f34 = "Vrinda"
and another avsi file that lists 140 colors,
i.e. global aliceblue=$F0F8FF ... global yellowgreen=$9ACD32
i.e. global c1=aliceblue ... global c140=yellowgreen

In the GScript code, I would like to increment f1 to f34 - i.e. display the 34 fonts in order
The problem is how can I use the for loop to increment values from f1 to f34

I tried renaming the fonts 1 to 34 in the avsi file but this doesn't work

I have also tried other ways:
for f(i) = 1 to 34
subtitle(f(i) ...

for i = 1 to 34
subtitle("f" + i ...
or
subtitle (f+"i" ...

Can I do this without using AVSLib to create some arrays?
[I would also like to increment the textcolor and/or halocolor]

Here is my script:
fontsize=40
vwidth=98*fontsize/2
vheight=72*fontsize/2
xspace=2
yspace=fontsize + 4
textcolor1=c8
halocolor1=c120
blankclip(60,vwidth,vheight,color=$ffffff)
text=" 0123456789 AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz"
GScript("""
for ( i = 1 , 34 , 1 ) {
subtitle(f3+text,x=xspace,y=i*fontsize,font=f3,size=fontsize,text_color=textcolor1, halo_color=halocolor1)
}
""")

The script works if I just use a font value, i.e f1 ... f34

You wantf3="f"+String(i)

[wiseant]

Hi Ian B

If I use "f"+String(i):

GScript("""
for ( i = 1 , 34 , 1 ) {
subtitle("f"+String(i)+text,x=xspace,y=i*fontsize,font="f"+String(i),size=fontsize,text_color=textcolor1, halo_color=halocolor1)
}
""")

This doesn't change the fonts - it uses the default font Arial and it justs outputs "f1" ... "f34" sequentially without translating the f-value to the corresponding font

If I use font=f3 for example it uses Arial Italic, font=f22 it uses Palatino Linotype Italic etc.
It works if I use 34 subtitle statements - I am trying to use one subtitle statement with the for loop

[-Vit-]

"f22" is not the same as f22. The first is a string literal that is always just "f22", the second is a string variable containing "Arial" or "Times" or whatever. Use Eval to evaluate expressions (in this case 'read a variable out of a string')

GScript("""
for ( i = 1 , 34 , 1 ) {
subtitle("f"+String(i)+text,x=xspace,y=i*fontsize,font=Eval("f"+String(i)),size=fontsize,text_color=textcolor1, halo_color=halocolor1)
}
""")

[Gavino]

That's right, but he probably wants the subtitle text to show the actual font name as well, rather than "f1", etc.
GScript("""
for ( i = 1 , 34 ) {
f = Eval("f"+String(i))
subtitle(f+text,x=xspace,y=i*fontsize,font=f,size=fontsize,text_color=textcolor1, halo_color=halocolor1)
}
""")
(Note that the for loop increment can be omitted as it defaults to 1.)

Hi -Vit-

Thanks - that works!

Hi Gavino - You beat me to it although yours is slightly different

I am using it like this now:

GScript("""
for ( i = 1 , 34 , 1 ) {
subtitle(Eval("f"+String(i))+text,x=xspace,y=i*fontsize,font=Eval("f"+String(i)),size=fontsize,text_color=textcolor1, halo_color=halocolor1)
}
""")

or as Gavino suggested:
GScript("""
for ( i = 1 , 34 ) {
f = Eval("f"+String(i))
subtitle(f+text,x=xspace,y=i*fontsize,font=f,size=fontsize,text_color=textcolor1, halo_color=halocolor1)
}
""")

This way it outputs the font name as well as the defined text
