findr - finding files without flags

I am impressed by the sheer amount of functionality offered by the Unix find command, but remain unable to remember how to use it for anything other than the basics; otherwise I hit Google. Obviously I don't have a very good memory for flags, but I do remember expressions. findr is given exactly two arguments; the base directory and a filter expression:

$ findr . 'path.ext=="rs" && path.size > 1kb' $ findr . 'path.is_file && date.before("1 jan")' $ findr . 'path.ext=="md" and date.after("last tuesday")'

The filter expression is passed path and date and fairly arbitrary expressions are supported, thanks to the very capable little embedded language rhai. As a little convenience, "and", "or" and "not" are understood, since these are easier to type in a hurry.

path has the following fields:

• is_file is this path a file?
• is_dir is this path a directory?
• size size of file entry in bytes
• ext extension of file path
• file_name file name part of path

date has the following methods:

• before(datestr) all files modified before this date
• after(datestr) all files modified after this date
• between(datestr,datestr) all files modified between these dates

Numbers may have a size prefix (kb,mb,gb - not case-sensitive) and date strings are interpreted by chrono-english.

Currently, findr ignores hidden directories.

By default, it speaks British English dates (i.e. not "9/11"), unless the environment variable FINDR_US is defined.

The "No Flags Mini-philosophy" remains important, and options should be few and controlled by environment variables.

To illustrate my point about flags, the equivalent of findr . 'path.ext="rs"' is:

find . -type d -path '*/\.*' -prune -o -not -name '.*' -type f -name '*.rs' -print

(I had to look that one up)
