I'm currently learning

Go (having somewhat learned Go templating via Hugo), back-end Nodejs, Drupal 10.

Coding is just a small part of who I am

Technology is a means to an end, and shiny tech is not always the best means.

I've worked as a human rights advocate, a community organizer, and a nonprofit communications manager. I've been on the board of a justice studies association, helped nominate people for the Nobel Peace Prize, wrote about third-party nonviolent intervention and used electronic civil disobedience to fight insecure voting systems.

Really all my technological expertise and interest stems from those larger objectives for social change.

I'm also active in 🚲 re-thinking urban spaces, 🥕 local food cooperatives, and 🔔 semi-professional handbell performance.

bash-scripts's Issues

Consider license change from GPL to AGPL

See https://www.gnu.org/licenses/why-affero-gpl.en.html among many other sources.

Flags w/arguments broken when using short+long

boilerplate/options.sh uses getopts, mostly from Schotts' example, with the addition of long versions (e.g. both -t and --time).

While this works with both short and long options in general, it seems to break for short options when the option is more than a boolean and requires an argument (e.g. --time=5 works; -t=5 doesn't).

Other variants I had found worked with space-separated arguments (instead of =) but worked either with short or long options, not both. Another option would be to have no argument-based flags, and only accept these as position-based arguments the way we're doing with videos/markvid.sh and videos/trimvid.sh.

Investigate if there are better solutions.

Scripts this affects (i.e. currently-broken short options with arguments): images/imagedate.sh, images/modimg.sh, videos/fadevid.sh, videos/minsmvid.sh.

imagedate: Move echo to printfs

Use printf instead of echo -e and change colors from ANSI to tput.

vidcap: if n > 11, skips every 12th, 22nd, etc. image

This line:

https://github.com/rootwork/bash-scripts/blob/main/videos/vidcap.sh#L307

is lazy. It works when there are fewer than 12 screencaps by simply skipping the 2nd (which is captured in the line prior and used as the top half image). But when there are 12 or more, it's going to skip every 12th, 22nd, 32nd, etc. image.

This should properly be a counter with a check when that counter equals (exactly) 2.

Implement "bash strict mode"

See http://redsymbol.net/articles/unofficial-bash-strict-mode/

This will require script-by-script implementation, with testing.

fadevid: Make time variable configurable in command-line

See e.g. imagedate
