vely:stat-file

stat-file

Purpose: Get information about a file.

stat-file <file> \
    size | type | path | name \
    to [ define ] <variable>

stat-file gets information about <file>, which is either the full path of a file or directory, or a name relative to the application home directory (see how_vely_works).

Clause "size" will store file's size in bytes to <variable>, or it will be VV_ERR_FAILED (if operation failed, likely because file does not exist or you have no permissions to access it).

Clause "type" will store file's type to number <variable>, and it can be either VV_FILE (if it's a file) or VV_DIR (if it's a directory) or VV_ERR_FAILED (if operation failed, likely because file does not exist or you have no permissions to access it).

Clause "path" gets the fully resolved path of the <file> (including symbolic links), and "name" is the name (a basename, without the path). The results of both "path" and "name" clauses are allocated memory. If path cannot be resolved, then <variable> is an empty string.

Examples

To get file size in variable "sz", which is created here:

stat-file "/home/user/file" size to define sz

To determine if the object is a file or a directory:

stat-file "/home/user/some_name" type to define what
if (what == VV_FILE) {
   @It's a file!
} else if (what == VV_DIR) {
   @It's a directory!
} else {
   @Doesn't exist!
}

Get the fully resolved path of a file to string variable "fp", which is created here.

stat-file "../file" path to define fp
