#' Set (replace) STICS input file parameters
#'
#' @description Replace or set an input parameter from a pre-existing
#'              STICS input file.
#'
#' @param workspace  Path of the workspace containing the STICS (txt)
#' input files.
#' @param param    Vector of parameter names.
#' @param value    New parameter value
#' @param append      Boolean. Append input to existing file
#' @param plant_id    The plant identifier (main crop: 1 ; associated crop: 2).
#' Only used for plant, technical or initialisation parameters (default = 1).
#' @param variety The plant variety to set the parameter value,
#' either the variety name (`codevar` in the plant file) or
#' the index (`variete` in the technical file).
#' @param value_id    The soil layers id or technical interventions id
#' @param stics_version An optional version name as listed in
#' get_stics_versions_compat() return
#' @param dirpath `r lifecycle::badge("deprecated")` `dirpath` is no
#'   longer supported, use `workspace` instead.
#' @param add `r lifecycle::badge("deprecated")` `add` is no
#'   longer supported, use `append` instead.
#' @param plant `r lifecycle::badge("deprecated")` `plant` is no
#'   longer supported, use `plant_id` instead.
#' @param layer `r lifecycle::badge("deprecated")` `layer` is no
#'   longer supported, use `value_id` instead.
#'
#' @param file Path (including name) of the file to modify
#' @param filepath `r lifecycle::badge("deprecated")` `filepath` is no
#'   longer supported, use `file` instead.
#'
#'
#' @details The \code{plant} parameter can be either equal to \code{1},
#'          \code{2} for the associated plant in the case of intercrop, or
#'          \code{c(1,2)} for both Principal and associated plants.
#'          \code{\link{get_var_info}} is a helper function that returns
#'          all possible output variables.
#'          If the \code{variety} is not given and if \code{param}
#'          is a varietal parameter, the function will modify the value of
#'          \code{param} for the simulated variety, as given
#'          in the technical file.
#'
#' @note \code{gen_varmod} is not used by \code{set_param_txt}.
#'       To replace the output variables required from STICS,
#'       please directly call \code{gen_varmod}.

#' Internal function to set some STICS input file parameters
#'
#' @description Replace or set an input parameter from a pre-existing
#'              STICS input file. This function is called by some of the
#'               generic \code{set_*} functions under the hood.
#'
#' @param file Path to the parameter file
#' @param param    Parameter name
#' @param value    New parameter value
#' @param append      Boolean. Append input to existing file
#' @param plant_id    The plant identifier (main crop: 1 ; associated crop: 2).
#' @param variety The plant variety to set the parameter value,
#' either the variety
#' name (`codevar` in the plant file) or the index
#' (`variete` in the technical file).
#' @param value_id index of technical interventions to be used to
#' set parameter values, or layer index for soil parameters
#' @param stics_version An optional version name as listed in
#' get_stics_versions_compat() return
#'
#' @details The function uses `base::sys.call()` to know from which function
#'          of the \code{set_*} family it is called, so it won't work properly
#'          if called by the user directly. This is why this function
#'          is internal.
#'
#' @note This function is not used for \code{\link{set_soil_txt}}.
#'
#' @seealso \code{\link{set_param_txt}}.
#'
#' @keywords internal
#'
#' @noRd
