Add a script to extract HTTP status values and format them
in a way that is both human readable and machine parseable.
Each line of output is of the form:
```
HTTP_{key}_{upper_val} = {key}, /**< val */
```

"""Format HTTP Status codes for use in a C header
|
|
|
|
This script extracts HTTP status codes from mozilla.org
|
|
and formats them to fit inside of a C enum along with
|
|
comments.
|
|
|
|
The output may appear somewhat redundant but it strives
|
|
to
|
|
a) be human readable
|
|
b) eliminate the need to look up status manually,
|
|
c) be machine parseable for table generation
|
|
|
|
The output is sorted for convenience.
|
|
|
|
Usage:
|
|
./scripts/net/enumerate_http_status.py
|
|
HTTP_100_CONTINUE = 100, /**< Continue */
|
|
...
|
|
HTTP_418_IM_A_TEAPOT = 418, /**< I'm a teapot */
|
|
...
|
|
HTTP_511_NETWORK_AUTHENTICATION_REQUIRED = 511, /**< Network Authentication Required */
