Gallerier error produced by list.files() output

[andrewsrs]

Having a problem using gallerier as well as the previous lightbox demo that seems to stem from a different implementation of list.files(). All of your code uses a line like this to create a source dataframe:

` images <- data.frame(src = list.files('www/img',full.names = T)) %>%
+     tidyr::separate(col = 'src', c('txt', 'date', 'time', 'msec'), sep = '_|\\.', remove = FALSE)`

But in my R version (4.2.1) list.files() returns a simple character vector of only filenames with no date or time so this statement produces an error like
Expected 4 pieces. Missing pieces filled with NAin 40 rows [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, ...].

This code seems to be embedded in the gallerier package making it unusable for me right now, as even the demo shiny app produces the same error. I'm sure this is something obvious I've overlooked--- any insight?
Thanks, Andrew

Hi @andrewsrs, sorry this bit of the example is probably confusing. The c('txt', 'date', 'time', 'msec') components are all coming from the filenames themselves. You can see my example files at https://github.com/mrjoh3/gallerier/tree/master/inst/shiny_module/www/img . The only field in the df that is used by the function is src so you can remove the tidyr::separate line.

At present this package is really only half way there, and the documentation needs to be completed. Essentially though, all the fields in the data.frame are used to create the image title within the gallery. Check out line 48 to see where and how this occurs https://github.com/mrjoh3/gallerier/blob/master/R/lightbox.R#L48
