add cli flag --alpha-layer

2023-01-28T10:23:11Z

now that we have long-opts, we don't have to worry about exhausting the alphabet list for short-opts. so adding a cli flag to set/unset the checker background makes sense. ref: https://codeberg.org/nsxiv/nsxiv/issues/404

improve error message on bad cli argument (#371)

2022-09-28T16:15:09Z

currently the error messages have the shortopt hardcoded in them, even when the user actually entered a longopt: $ ./nsxiv --framerate v nsxiv: Invalid argument for option -A: v and as far as I see, there's no way to *reliably* tell weather we're processing a longopt or a shortopt. perhaps we can do some shenanigangs with `optind` but that seems finicky at best. and it seems like other coreutils which support longopt has similar issues: $ xargs --max-procs=z xargs: invalid number "z" for -P option utils like `grep` and `head` seems to work-around it by not mentioning the flag: $ head --lines=z head: invalid number of lines: ‘z’ $ grep --max-count=l grep: invalid max count this patch does the same thing as `grep/head` and omits the flag from the error message.

fix potential truncation of cli arguments (#367)

2022-09-14T04:58:41Z

strtol() returns a `long`, but we're storing the result in an `int` which might end up getting truncated. change `n` to `long` and guard against >INT_MAX arguments in cases where it matters. use a float for storing argument of `-S` change `opt.slideshow` to `unsigned` similar to `img.ss.delay` Co-authored-by: Berke Kocaoğlu Reviewed-on: https://codeberg.org/nsxiv/nsxiv/pulls/367 Reviewed-by: Berke Kocaoğlu Reviewed-by: explosion-mental

rename: aa -> anti_alias

allow disabling anti-aliasing via cli flag

2022-09-10T13:43:07Z

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

don't assume positive argc

2022-09-05T01:52:51Z

handle a rare, but possible case of argc being 0, in which case argv[0] would be null. note that both POSIX and ISO C standard allow argc to be 0 and in practice this can be triggered via calling `exec(3)` family of functions with NULL as the first `argv`.
