Write the C code to a file

This function does not compile the code, it only writes it to a file in a temporary location (tempdir). By default, the name of the file will contain the hash of the entire code.

Usage

write_c_code(
  C,
  model.name = comment(C),
  file = file.path(tempdir(), digest::digest(C, "xxhash64"), paste0(model.name, ".c"))
)

Arguments

C

the code to write, as a character array.

model.name

a string with no special characters, will be used in the file name

file

override the default file name (based on hashing)

Value

the path of the written file

Details

If instead of a character vector, an ode or cme object is passed, this function will generate code from it with default options.

Examples

m <- model_from_tsv(uqsa_example("AKAR4"))
o <- as_ode(m)
C <- generate_code(o)
c_path(o) <- write_c_code(C)
print(o)
#>                 Model name : AKAR4
#>                     C file : /tmp/RtmpgX4tEN/adf9204aaf2748b8/AKAR4.c [2026-05-04 10:58:47.805147]

if (file.exists(c_path(o))) cat("c file exists.\n")
#> c file exists.
