* Remove the dependency on clapMiquel Sabaté Solà2025-01-222-18/+62
| | | | | | | | | | | | | | | All three binaries (i.e. readrom, nasm and xa65) used it, and to be honest rolling our own argument parsing was actually pretty easy to achieve. This frees us from a big dependency and it also frees us from inner dependencies such as 'clap_derive' which prevented us from being able to build binaries purely statically. As a side effect, we can now display help/version messages which are more like I'm used to, and certain checks can be moved in the parsing directly instead of having to be done later. As a cherry on top, there is some type masturbation that gets removed along the way. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>

* readrom: Remove the derive feature from clapMiquel Sabaté Solà2025-01-102-14/+18
| | | | | | | This allows us to statically build the 'readrom' binary, as that feature from clap prevented that option. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Remove anyhow from xa65 and readromMiquel Sabaté Solà2025-01-102-9/+17
| | | | | | | | Following in the footsteps of c20c991dded8 ("Make errors from nasm itself more cohesive"), 'anyhow' might provide an easy framework, but it lends towards a less cohesive experience. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Add the readrom binaryMiquel Sabaté Solà2024-12-182-0/+67
The readrom binary is similar to `readelf` from Linux and it will allow to display information from an NES/Famicom ROM file. For now the information being shown is just the header, but in the future we might also include disassembling parts of the code, or retrieving the "CHARS" section for a given ROM file, and similar. In order to implement the header parsing part a new library has been introduced, simply named "header" which abstracts everything away so you just need to call `Header::try_from("my bytes")` to fetch the actual information.
