- Deduplicate the logic used by write-out and write-out json.
Rather than have separate writeLong, writeString, etc, logic for
each of write-out and write-out json instead have respective shared
functions that can output either format and a 'use_json' parameter to
indicate whether it is json that is output.
This will make it easier to maintain. Rather than have to go through
two sets of logic now we only have to go through one.
- Support write-out %{errormsg} and %{exitcode} in json.
- Clarify in the doc that %{exitcode} is the exit code of the transfer.
Prior to this change it just said "The numerical exitcode" which
implies it's the exit code of the tool, and it's not necessarily that.

Help: Use output FORMAT after completion
|
|
Category: verbose
|
|
---
|
|
Make curl display information on stdout after a completed transfer. The format
|
|
is a string that may contain plain text mixed with any number of
|
|
variables. The format can be specified as a literal "string", or you can have
|
|
curl read the format from a file with "@filename" and to tell curl to read the
|
|
format from stdin you write "@-".
|
|
|
|
The variables present in the output format will be substituted by the value or
|
|
text that curl thinks fit, as described below. All variables are specified as
|
|
%{variable_name} and to output a normal % you just write them as %%. You can
|
|
output a newline by using \\n, a carriage return with \\r and a tab space with
|
|
\\t.
|
|
|
|
The output will be written to standard output, but this can be switched to
|
|
standard error by using %{stderr}.
|
|
|
|

|
|
The %-symbol is a special symbol in the win32-environment, where all

occurrences of % must be doubled when using this option.
