- Finished implementing relative date parsing and migrated date parsing from Flag(T) to it's own dedicated module. Additionally added a the ability to do "recursive" relative operations for time searching. - Additionally made a Struct & Enum for containing relative operations around dates. - Added additional checks in App & CommandNode(T) around checking env_vars of flags & checking for duplicate commands - Added a CommandMeta record to contain the classname of the CommandNode(T) - Seperated out all of the monolitic files (command_node.cr & file.cr). Moved the base classes and records into their own files in the dir with the same name of their generic counterparts. - Fixed a number of macro related bugs around Command.argument & CliGen.add_global_flag - My ass hurts from sitting here for hours and doing these changes and arguing with claude over what needs to be done. Fun tho.

# Manual harness for flag resolution + validation across every source a value
|
|
# can arrive from. Driven by ./utils/flag_matrix.sh; see that script for the expected
|
|
# results. Kept out of spec/ because each case needs its own process (env vars
|
|
# must be set before startup).
|
|
#
|
|
# ENV VAR NAMING - the two kinds of flag derive their names differently:
|
|
#
|
|
# global flag add_global_flag(..., long: "--retries") -> RETRIES
|
|
# derived from the long flag, minus the leading dashes
|
|
#
|
|
# command arg class Greet; argument(level : Int32 ...) -> GREET_LEVEL
|
|
# derived as <COMMAND>_<VAR>, see app/generate.cr
|
|
#
|
|
# The asymmetry is easy to trip over: exporting LEVEL=9 does nothing at all,
|
|
# because the command argument is bound to GREET_LEVEL.
