v1.0

New features and improvements

• Added utilities for getting raw arguments, and added the option to allow unused parameters that could be parsed separately by the user
• Added argument constraints
• Utilities for printing help in fired_main() and properly raising errors
• Improved error messages
• Improved documentation of internals, including a write-up of the library's algorithm
• Minor fixes

The library is finally stable! It's been a long journey.

v0.2

v0.2 is mostly a matured version of v0.1, in a sense that not many new features were added, however existing features were improved. In summary, a lot of breaking changes and a lot of internal structural changes. The rationale is to make most of the breaking changes early in development, so that new features can be added to a "more final" version of the library.

Release notes

Breaking changes:

• Include fire as <fire-hpp/fire.hpp> not <fire.hpp>.
• Hyphens are also written when specifying argument names. So instead of fire::arg("x") and fire::arg("long-name") you write fire::arg("-x") and fire::arg("--long-name").
• Name/position and description are now both the first argument. Eg. now it's fire::arg({name, description}, default value) instead of fire::arg(name, description, default value).
• Variadic arguments are now specified as fire::arg(fire::variadic()) instead of fire::arg::vector().
• No more FIRE_NO_SPACE_ASSIGNMENT(...).

New library features:

• FIRE(...) now works with positional/variadic argument, previously needed FIRE_NO_SPACE_ASSIGNMENT(...). This was a HUGE change internally, had to implement a totally new argument introspection algorithm.
• fire.hpp now compiles without exception support, but you need to use FIRE_NO_EXCEPTIONS(...) instead of FIRE(...), which has limitations.
• Program descriptions.
• Positional arguments can be supplied with custom names.

Improvements:

• In program -- --some-text --some-text is interpreted as positional, per convention.
• Much cleaner help messages. Clarified a few error messages too.
• Accept arguments in a manner similar to make -j8 <=> make -j 8 if unambiguous.
• Misc bug fixes.

Integration

• CMake integration. (thanks cxkoda).
• Conan package (https://conan.io/center/fire-hpp) (thanks axalon900).

v0.1

Features:

• Flags, named, positional, vector parameters
• Optional parameters, default values
• Conversions to arithmetic types
• Parameter descriptions
• All of this using just function signatures
