Syntax highlighting complex filename extensions

[wanderer]

Is it possible to uniquely identify a file extensions like filename.c.txt from other files whose extension might be filename.txt for the purpose of using different syntax highlighting ?

No, definitively not.

The file extension is defined by Microsoft as the characters AFTER the last dot. All characters BEFORE the last dot are part of the file name. The dot itself does not belong to the file extension nor the file name. It is the delimiter. File name + dot + file extension build the name of a file. That feature you want could only be used, if UE would accept wildcards for syntax highlighting, for example *.c.txt, instead of only using the file extension.

But you can switch the syntax highlighting used for the current file manually by selecting the one you want from the menu View - View As (Highlighting File Type).

But this is not stored and must be set manually for each file and every time UE is started again.

As a to followup on Mofi's answer, you could create various Key Mappings for different Language syntaxes to more quickly convert to them. For instance, I have a number of .TXT files that predominently contain SQL examples, and I've mapped Alt-Q to switch to View As... SQL (Language 13 for me), so after I've opened the file I can quickly display it to show SQL syntax highlighting.

Just a thought.

Many thanks for the clarification and ideas. I will manually choose highlighting theme thru the | view as... | menu.

Hello,

I'm using files that are using ".css.dtml" as extensions (it is css files) and I'd like to associate it with the CSS syntax highlighting. Of course I cannot use only ".dtml" because other files are using it.

I tried to simply add "CSS.DTML" on my wordfile but it does not work.

Is it possible to do this ?

Sorry, but this is not possible. The file extension is according to the specification from Microsoft only the part after last point. For example a file named "file.css.dtml" has the filename "file.css" and the extension "dtml". I personally avoid more than 1 point in the name of the file. I always use an underscore as word "delimiter" in a filename.

From help of UE about syntax highlighting:

File Extensions/Types

Syntax Highlighting is determined either by the name of the file or its extension. More commonly the extension is used and to specify the extensions for which this language is applicable the following string should be used: "File Extensions = " and each extension is separated by a space.

To specify that a filename is to be used to determine the language the following string should be used: "File Names = " and each name is separated by a space.

So you can also use File Names = if you do not have too much CSS files with the wrong extension. But it is not possible to specify "File Extensions = " and "File Names = " for the same language definition. You have to copy the whole CSS language definition block and insert it before the language definition for files with the extension CSS and DTML. Example:

/L3"CSS.DTML" File Names = ....

/L4"DTML" File Extensions = DTML

/L5"CSS" File Extensions = CSS

And you cannot use wildcards in the "File Names = " specification!

Well, because I have quite a lot of different files like this (due to the system we have to keep the "double" extension), I will keep choosing the colorization manually : that's not too difficult

Thanks for your answer : I'll look at deeper the documentation next time.
