ort_lang_c_source — generate node.js implementation of openradtool configuration

library “libort-lang-nodejs”

#include <sys/queue.h>
#include <stdio.h>
#include <ort.h>
#include <ort-lang-nodejs.h>

int
ort_lang_nodejs(const struct ort_lang_nodejs *args, const struct config *cfg, FILE *f);

Outputs a node.js implementation of the parsed configuration cfg to f. The values in args are as follows:

unsigned int flags
The bit-field of components to output.

The following components are output if specified:

Generate the data structures.
Generate database routines. This stipulates a dependency on the "better-sqlite3" and "bcrypt" packages.
Generate the validation namespace. This stipulates a dependency on the "validator" package.

If args is NULL, it defaults to all values being zero.

Returns zero on failure, non-zero on success. Failure only occurs with memory allocation errors or when writing to f.

The following emits a configuration as read from standard input to node.js as written to standard output.

struct config *cfg;
struct ort_lang_nodejs args;

memset(&args, 0, sizeof(struct ort_lang_nodejs));
args.flags = ORT_LANG_NODEJS_CORE|ORT_LANG_NODEJS_DB;

if ((cfg = ort_config_alloc()) == NULL)
  err(1, NULL);
if (!ort_parse_file(cfg, stdin, "<stdin>"))
  errx(1, "ort_parse_file");
if (!ort_parse_close(cfg))
  errx(1, "ort_parse_close");
if (!ort_lang_nodejs(&args, cfg, stdout))
  err(1, "ort_lang_nodejs");

ort_config_free(cfg);

Alternatively, this could be converted into a string:

char *buf = NULL;
size_t bufsz = 0;

/* Read and parse configuration as above... */

if ((stream = open_memstream(&buf, &bufsz)) == NULL)
  err(1, "open_memstream");
if (!ort_lang_nodejs(&args, cfg, stream))
  err(1, "ort_lang_nodejs");
fclose(stream);

/* Do something with buf of size bufsz. */

free(buf);
