[PJSR] Method to clean file name

[bitli]

Hello,
I use data of FITS fields (as EXTNAME) to create a file name.  Is there a method to 'clean' a file name, that is to remove/transform characters that may be troublesome (.., / \, quotes, ....).  I have seen nothing in Files.
Same question to create a PI identifier from an arbitrary text (as replacing _ par -, or something).  Naturally the transformation is not invertible and do not maintain unicity, but this could be convenient.

create a PI identifier from an arbitrary text

How about this:

Code: [Select]

function toValidViewId( s )
{
   return s.replace( /[^_a-zA-Z0-9]/g, '_' ).replace( /[^_a-zA-Z]/, '_' );
}
Edit: fix a problem with strings starting with a decimal digit.

Fine by me, didn't know if there was already a 'standard' way (although it should probably not start by a digit also).
tks.

May also want to guarantee that name is not empty ""? May want to trim off leading and trailing spaces?

Hi Juan,

Your decimal digit fix introduced a bug. Should apply to first character only (add another ^ to second replace):

Code: [Select]

return s == "" ? "_" : s.replace( /[^_a-zA-Z0-9]/g, '_' ).replace( /^[^_a-zA-Z]/, '_' );
