Parameterized, project-based file paths

Source: R/glue_here.R
glue_here.Rd

Quick wrapper around stringr::str_glue and here::here to fill a small recurring need: filling in file paths based on some parameter, but building them relative to the project root.

Usage

glue_here(x, ..., .snake = TRUE, .envir = environment())

Arguments

x

Character vector of paths, relative to the project root, with glue-style encodings.

...

Additional named arguments to fill into glue brackets

.snake

Boolean, whether text should also be converted to snakecase. Default: TRUE

.envir

Environment to be passed down stringr::str_glue. Probably don't need to worry about it.

Value

A character vector of absolute paths with glue strings filled in.

Examples

glue_here("{year}_headings_{topic}.txt", year = 2025, topic = "education")
#> [1] "/tmp/RtmppBoLkc/file1e9f3a8215d7/2025_headings_education.txt"

# in a regular script you shouldn't need to worry about setting .envir
# but scoping is weird for package examples
# year <- 2025
# loc <- "New Haven"
env <- rlang::env(year = 2025, loc = "New Haven")
glue_here(c(
    "input_data/demo/{loc}_table_{year}.csv",
    "{year}_headings.txt"
), .envir = env)
#> [1] "/tmp/RtmppBoLkc/file1e9f3a8215d7/input_data/demo/new_haven_table_2025.csv"
#> [2] "/tmp/RtmppBoLkc/file1e9f3a8215d7/2025_headings.txt"
