Write the C code to a file — write_c

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/Rtmp3WxBip/adf9204aaf2748b8/AKAR4.c [2026-05-15 14:26:39.553243]

#>            Transformations : no
if (file.exists(c_path(o))) cat("c file exists.\n")
#> c file exists.
