The goal of stringpool is to help developers understand R’s global string pool.
You can install the development version of stringpool like so:
pak::pak("krlmlr/stringpool")
library(stringpool)
Use stringpool() to get all strings currently known to R as a character vector:
lapply(head(stringpool()), charToRaw) #> [[1]] #> raw(0) #> #> [[2]] #> [1] e3 82 99 #> #> [[3]] #> [1] e3 80 aa #> #> [[4]] #> [1] e3 80 ae #> #> [[5]] #> [1] 09 #> #> [[6]] #> [1] 0a
If you need to understand the evolution of the global string table, writing to disk is a good idea.
path1 <- tempfile(fileext = ".txt") write_stringpool(path1, sep = "=====\n") fs::file_info(path1) #> # A tibble: 1 × 18 #> path type size permiss…¹ modification_time user group devic…² #> <fs::path> <fct> <fs:> <fs::per> <dttm> <chr> <chr> <dbl> #> 1 …da32838fef0.txt file 390K rw-r--r-- 2023-04-08 13:32:19 kiri… staff 1.68e7 #> # ℹ abbreviated names: ¹permissions, ²device_id #> # ℹ 10 more variables: hard_links <dbl>, special_device_id <dbl>, inode <dbl>, #> # block_size <dbl>, blocks <dbl>, flags <int>, generation <dbl>, #> # access_time <dttm>, change_time <dttm>, birth_time <dttm> path2 <- tempfile(fileext = ".txt") write_stringpool(path2, sep = "=====\n") fs::file_info(path2) #> # A tibble: 1 × 18 #> path type size permiss…¹ modification_time user group devic…² #> <fs::path> <fct> <fs:> <fs::per> <dttm> <chr> <chr> <dbl> #> 1 …da335e95331.txt file 520K rw-r--r-- 2023-04-08 13:32:19 kiri… staff 1.68e7 #> # ℹ abbreviated names: ¹permissions, ²device_id #> # ℹ 10 more variables: hard_links <dbl>, special_device_id <dbl>, inode <dbl>, #> # block_size <dbl>, blocks <dbl>, flags <int>, generation <dbl>, #> # access_time <dttm>, change_time <dttm>, birth_time <dttm>
