Support full .gitignore syntax in .rcsignore

[ColinFay]

Issue

The . rcsignore file doesn't work with :

1. folders that are listed as folder/ instead of folder
2. files that are in subdirectories

Diagnosis

1. For dev/ : the setdiff here is not smart enough :

   rsconnect/R/bundleFiles.R

   Line 200 in cf0972d

   if (".rscignore" %in% contents) {

list.files() (that created the contents object) will do

[1] "DESCRIPTION" "dev"         "inst"        "man"         "NAMESPACE"  
[6] "R" 

When a directory can usually be written folder/ in an ignore file.

2. The list file that creates the contents object doesn't list subfolders: recursiveBundleFiles doesn't do a recursive in the list file

   rsconnect/R/bundleFiles.R

   Line 137 in cf0972d

   contents <- list.files(dir, all.files = TRUE, no.. = TRUE)

How to reproduce

1. Go to /tmp & create a golem app:

; cd /tmp && Rscript -e 'golem::create_golem("reprexrsconnect")' && cd reprexrsconnect

4. Add 'DESCRIPTION' to .rscignore => works as expected

; echo 'DESCRIPTION' >> .rscignore  
; ls
DESCRIPTION     NAMESPACE       R               dev             inst            man
; Rscript -e 'rsconnect::listDeploymentFiles(".")'
 [1] ".here"                    ".Rbuildignore"           
 [3] "dev/01_start.R"           "dev/02_dev.R"            
 [5] "dev/03_deploy.R"          "dev/run_dev.R"           
 [7] "inst/app/www/favicon.ico" "inst/golem-config.yml"   
 [9] "man/run_app.Rd"           "NAMESPACE"               
[11] "R/app_config.R"           "R/app_server.R"          
[13] "R/app_ui.R"               "R/run_app.R"

5. Trying to ignore dev/ => doesn't work

; echo 'dev/' >> .rscignore
; Rscript -e 'rsconnect::listDeploymentFiles(".")'
 [1] ".here"                    ".Rbuildignore"           
 [3] "dev/01_start.R"           "dev/02_dev.R"            
 [5] "dev/03_deploy.R"          "dev/run_dev.R"           
 [7] "inst/app/www/favicon.ico" "inst/golem-config.yml"   
 [9] "man/run_app.Rd"           "NAMESPACE"               
[11] "R/app_config.R"           "R/app_server.R"          
[13] "R/app_ui.R"               "R/run_app.R"      

6. Trying to ignore dev/01_start.R => doesn't work

 ;echo 'dev/01_start.R' >> .rscignore 
 [1] ".here"                    ".Rbuildignore"           
 [3] ".rscignor"                "dev/01_start.R"          
 [5] "dev/02_dev.R"             "dev/03_deploy.R"         
 [7] "dev/run_dev.R"            "inst/app/www/favicon.ico"
 [9] "inst/golem-config.yml"    "man/run_app.Rd"          
[11] "NAMESPACE"                "R/app_config.R"          
[13] "R/app_server.R"           "R/app_ui.R"              
[15] "R/run_app.R"             

7. Printing the rscignore just to be sure

; cat .rscignore 
DESCRIPTION
dev/
dev/01_start.R

Happy to help with submitting a patch if you want :)

Do you mind creating a reprex for me? The following code looks correct to me.

library(rsconnect)

dir <- withr::local_tempdir()
dir.create(file.path(dir, "a", "b"), recursive = TRUE)
file.create(file.path(dir, c("x", "a/y", "a/b/z")))
#> [1] TRUE TRUE TRUE
listDeploymentFiles(dir)
#> [1] "a/b/z" "a/y"   "x"

writeLines("y", file.path(dir, "a", ".rscignore"))
listDeploymentFiles(dir)
#> [1] "a/b/z" "x"

writeLines(c("y", "b"), file.path(dir, "a", ".rscignore"))
listDeploymentFiles(dir)
#> [1] "x"

^{Created on 2023-03-16 with reprex v2.0.2}

Or are you asking about this?

#' *  You can exclude additional files by listing them in in a `.rscignore`
#'    file. This file must have one file or directory per line (with path
#'    relative to the current directory). It doesn't support wildcards, or
#'    ignoring files in subdirectories.

This is not technically supported, but it's a popular request, so I'll bite the bullet and implement it. See implementation in renv for a starting point: https://github.com/rstudio/renv/blob/main/R/renvignore.R.

Looking forward, should read both .rscignore and .connectignore.
