How do I remove spaces and special characters from the file name during rendering?

[Jubilant_kindness0D4C]

I understand that I can set LR_renamingTokensOn to true, but I would like to replace all spaces in the file name with an underscore and remove characters not in the range A-Z and 0-9. What's the easiest way to achieve this?

Well, if it's an ad-hoc export, i.e. one which your plugin initates via an LrExportSession method, then you can name stuff whatever you want to - just set  LR_tokens to {{custom_token}} then set LR_tokenCustomString to whatever you want (a filtered filename base).

Are you writing a:

* export/publish plugin

* export filter to be used with any export/publish service.

* something else (e.g. menu function), which could use ad-hoc exporting

?

Hi Rob,

I can set LR_tokens since the export is done via a custom initiation of LrExportSession, but I find the documentation on it confusing.

I'm writing an export plugin.

Can you provide some sample code for using {{custom_token}} that would run a regular expression on the filename?

Thanks.

local photo = catalog:getTargetPhoto()

local sesn = LrExportSession {

    photosToExport = { photo },

    exportSettings = {

        -- ... (determine from export preset) - whatev you want, just be sure you set export directory: LR_export_destinationPathPrefix

        LR_tokens = "{{custom_token}}",

        LR_tokenCustomString = LrPathUtils.removeExtension( photo:getFormattedMetadata( 'fileName' ) ):gsub( "[ %c]", "" ) -- remove spaces and control characters

    },

}

sesn:doExportOnNewTask()
