## Version 0.5 (in progress)
|
||||
|
||||
* `->ignore_case()` added to subcommands, options, and `add_set_ignore_case`. Subcommand inherit setting from parent App on creation.
|
||||
* Subcommands now can be "chained", that is, left over arguments can now include subcommands that then get parsed. Subcommands are now a list (`get_subcommands`). Added `got_subcommand(App_or_name)` to check for subcommands. (untested)
|
||||
* Added `.allow_extras()` to disable error on failure. Parse returns a vector of leftover options. Renamed error to `ExtrasError`, and now triggers on extra options too. (untested)
|
||||
* Added `require_subcommand` to `App`, to simplify forcing subcommands. Do not "chain" with `add_subcommand`, since that is the subcommand, not the master `App`.

|
||||
* Added printout of ini file text given parsed options, skips flags.
|
||||
* Support for quotes and spaces in ini files
|
||||
* Fixes to allow support for Windows (added Appveyor) (Use `-`, not `/` syntax)

* Collect user feedback
|
||||
* Ini configuration support is basic (long options only, no vector support), is more needed?
|
||||
* Evaluate compatibility with [ROOT](https://root.cern.ch)'s TApplication object.
|
||||
* Add tests: Add way for subclasses to return remaining options rather than throwing error
|
||||
* Chained subcommands are not tested, once a subcommand is given the rest of the options go to that subcommand, rather than allowing multiple subcommands. This is currently intentional behavior, but multiple base level subcommands, like [`Click`](http://click.pocoo.org) supports, might be considered in the future.
|
||||
* Throw error if `ignore_case` causes non-unique matches

|
||||
|
||||
All `App`s have a `get_subcommands()` method, which returns a list of pointers to the subcommand passed on the command line. A simple compare of these pointers to each subcommand allows choosing based on subcommand, facilitated by a `got_subcommand(App_or_name) method that will check the list for you. For many cases, however, using an app's callback may be easier. Every app executes a callback function after it parses; just use a lambda function (with capture to get parsed values) to `.add_callback`. If you throw `CLI::Success`, you can
|
||||
even exit the program through the callback. The main `App` has a callback slot, as well, but it is generally not as useful.
|
||||
|
||||
Multiple subcommands are allowed, to allow [`Click`](http://click.pocoo.org) like series of commands (order is preserved). If you want only one, throw `CLI::Success` or only process one.
