File Info Tips and Tiles

You can use the evaluator in the definitions for file info tips and tiles mode to insert text returned by the evaluation.

Use the {= ... =} code to insert an evaluation expression. The expression between the {= and the =} markers can span multiple lines if needed. The return value of the expression is inserted into the info tip or tile.

You can also implement hide sections using the evaluator - use {!= ... =} to open the hide section with an evaluation expression. If the expression returns false, everything within the hide section will be hidden. Close the hide section with {!} as normal.

In this evaluation context, the following variables are available:

Variable	Type	Description
column name	varies	All the column keywords are available as variables in this evaluation context. Note that some keywords may use characters like a : that aren't valid in variable names - to access them, use the Val function. Additionally, the keywords foldersize, foldercontents and infotip are also supported.
file_name	string	Returns the full name of the file the expression is being run for. This may be different from file which (as a column keyword), returns the value of the Name column (which e.g. may have file extensions hidden).
is_dir	bool	True if the expression is being run for a folder, false if it's being run for a file.

All the column keywords are available as variables in this evaluation context.

Note that some keywords may use characters like a : that aren't valid in variable names - to access them, use the Val function.

Additionally, the keywords foldersize, foldercontents and infotip are also supported.

file_name

string

Returns the full name of the file the expression is being run for. This may be different from file which (as a column keyword), returns the value of the Name column (which e.g. may have file extensions hidden).

is_dir

bool

True if the expression is being run for a folder, false if it's being run for a file.

The return value should either be a str for an insertion, or a bool for a hide section.

If the expression is an insertion (using the {= ... =} code), the return value from the evaluation expression will be inserted into the info tip or tile at the point where the code appeared.
If the expression is for a hide section (using the {!= ... =} code), it should return true to show the contents of the hide section, or false to hide them.
