Formatting the custom output file name  

Formatting the custom output file name

Hei there,

I wonder if anybody knows about a way to format the custom output file name. I am aware of the template placeholders that I can use to impact the way the output filename of the stl file is generated.  That is already good. But I am missing some more minor features

1. Formatting template output into e.g. upper or lowercase letters.
   It seems that output variables are a mix of uppercase and lowercase letters. The filament type is all uppercase (PLA, PETG), while for example the nozzle is lower case (0.4n), as is the layer height. This generates output filenames with a mixed upper and lower case letter combinations. Unless you actively choose the sorting, on e.g. Linux systems the lower case will always be sorted before the uppercase filenames. One way of partially controlling this is to use the custom part of the project filename to influence the writing.
2. Replacing/adding/removing parts of variables
   I use the date of when a file has been created as the first part of a project filename (m3f), but I structure the types of print differently with an uniq ID. The generated STL output filename does not need the date, but should keep the ID so I know exactly what model I am printing. Currently I cannot automatically remove that part from the template variable with the custom name filter. If I could use e.g. a regex expression within the template variable, I could cut or amend any string to the variable or even replace certain values.

   So a project filename like 19700101-foobar-01.01.foobar.m3f (01.01 is the id) should generate 01.01-foobar.stl as output filename.

My gutt-feeling tells me we are at the beginning of what is possible with formatting the  output filename and this is currently just wishful thinking. But I might have missed this functionality somewhere in the document. Maybe?
