2022-10-07[ci]: try building all combination with tcc (#338)NRK
this will hopefully catch issues like [337] in the future. not using gcc and/or clang since we have 5 build options right now, which means 2^5 = 32 different combination. using gcc/clang would take too much resources and time; meanwhile tcc is lightning fast.

2022-09-10allow disabling anti-aliasing via cli flagNRK
simply running nsxiv with `--anti-alias` will enable anti-aliasing, and running it with `--anti-alias=no` will disable it. the cli flag will overwrite the config.h default. Closes: https://codeberg.org/nsxiv/nsxiv/issues/349
2022-09-05[ci]: disable noisy checks (#365)NRK
* disable `cert-err33-c` and `readability-identifier-length` check which causes warnings on clang-tidy v14. * disable all "readability" checks by default, instead just opt-into the useful ones (such as duplicate include).

2022-08-19Misc docs cleanup (#362)NRK
* link to online man-page * rename: "N-R-K" -> "NRK" * separate multiple links with a comma. otherwise the links get messed up due to `[] []` being valid syntax for reference style links with the 2nd `[]` serving as `id`. * prefer codeberg links over github ones Reviewed-on: https://codeberg.org/nsxiv/nsxiv/pulls/362 Reviewed-by: explosion-mental <explosion-mental@noreply.codeberg.org>
2022-08-16add support for long-opts (#332)NRK
Uses [optparse] to add support for long-opts. optparse is posix compliant with getopt(3) and thus would be backwards compatible. It does not have any dependency (not even the c standard library!) and is C89 compatible and thus fits our current code-style. [optparse]: https://github.com/skeeto/optparse Note that we're using a couple `pragma`-s to silence some harmless warnings. This should be portable because these pragma-s don't change the behavior of the program. Furthermore, C standard mandates that unknown pragma's should be ignored by the compiler and thus would not result in build failure on compilers which do not recognize them.

2022-08-09Move uncritical files into `etc/` (#350)NRK
This is mainly just to reduce the amount of files in the project root. The criteria of what gets into `etc/` are the following: * The file should not be necessary for building nsxiv. This excludes the `icon/*` stuff since that's needed by `window.c`. * The file shouldn't have any valid reason to stay in the project root. This excludes things like `README.md`, `.gitignore` etc. Reviewed-on: https://codeberg.org/nsxiv/nsxiv/pulls/350 Reviewed-by: explosion-mental <explosion-mental@noreply.codeberg.org>
