Loop through similar files and execute commands for that

[countryqt30]

Hey guys,

I'd like to achieve the following:

Find all files ending with ".hlsl", "fxc" them with an input of ".psh" and ".vsh". Okay, seems a bit confusing, so here is an example:

Code: Select all

fxc /T vs_5_0 /E VxShader /Fo Terrain.vsh Terrain.hlsl
fxc /T ps_5_0 /E PxShader /Fo Terrain.psh Terrain.hlsl

In this case, the target name is "Terrain.hlsl". Unfortunately, this is doing it's job very well - but only for one file at once. Doing this for many files can become very very confusing and is unclear style i think.

So i need to do these 2 steps for EVERY *.hlsl file in the current directory.
How would i do this? Can this be done with batch or should I use something else?

You could use a simple FOR loop.
Untested:

Code: Select all

for %%i in (*.hlsl) do (
  fxc /T vs_5_0 /E VxShader /Fo "%%~ni.vsh" "%%i"
  fxc /T ps_5_0 /E PxShader /Fo "%%~ni.psh" "%%i"
)

@aGerman
Thank you, it works like a charm!

Can you explain what "%%~ni.vsh" really stands for? I know it means the <old name without extension> + ".vsh" but this CMD syntax is more than strange..
It's like hell for every scripter i think.

It's one of the well documented options of FOR variables. Execute FOR /? to get the help message.

Code: Select all

[...]
    %~nI        - expands %I to a file name only
