|
|
|
|
OPTIONS
|
|
|
|
-p, --pubkey <public key> The hex public key of user whose events and feed are shown. Default is a hard-coded
|
|
well known private key. When given, posts/replies can't be sent.
|
|
-k, --prikey <private key> The hex private key of user whose events and feed are shown. Also used to sign events
|
|
sent. Default is a hard-coded well known private key.
|
|
-r, --relay <relay wss url> The relay url that is used as main relay. Default is wss://relay.damus.io.
|
|
-d, --days <N as num> The latest number of days for which events are shown. Default is $gDefaultNumLastDays.
|
|
-q, --request <REQ string> This request is sent verbatim to the default relay. It can be used to recieve all events
|
|
from a relay. If not provided, then events for default or given user are shown.
|
|
-f, --file <filename> Read from given file, if it is present, and at the end of the program execution, write
|
|
to it all the events (including the ones read, and any new received). Even if not given,
|
|
the default is to read from and write to $gDefaultEventsFilename . Can be turned off by
|
|
the --disable-file flag
|
|
-s, --disable-file When turned on, even the default filename is not read from.
|
|
-t, --translate Translate some of the recent posts using Google translate site ( and not api). Google
|
|
is accessed for any translation request only if this flag is present, and not otherwise.
|
|
|
|
UI Options
|
|
-a, --align <left> When "left" is given as option to this argument, then the text is aligned to left. By default
|
|
the posts or text is aligned to the center of the terminal.
|
|
-w, --width <width as num> This specifies how wide you want the text to be, in number of columns. Default is $gDefaultTextWidth.
|
|
Cant be less than $gMinValidTextWidth.
|
|
-m, --maxdepth <depth as num> The maximum depth to which the threads can be displayed. Minimum is $gMinimumDepthAllowed and
|
|
maximum allowed is $gMaximumDepthAllowed.
|
|
-c, --color <color> Color option can be green, cyan, white, black, red and blue.
|
|
-h, --help Print this usage message and exit.
|
|
|
|
Advanced
|
|
-y, --difficulty <number> The difficulty number in bits, only for kind 1 messages. Tne next larger number divisible by 4 is
|
|
taken as difficulty. Can't be more than 24 bits, because otherwise it typically takes too much
|
|
time. Minimum and default is 0, which means no difficulty.
|
|
-v, --overwrite Will over write the file with all the events that were read from file, and all newly received. Is
|
|
useful when the file has to be cleared of old unused events. A backup should be made just in case
|
|
of original file before invoking.

HOW TO USE
|
|
----------
|
|
|
|
* When entering a event you want to reply to, you need to enter only the first few letters of the event-id. Lets say the event is
|
|
|
|
+-------+
|
|
|Author : vishalxl id: 6c1 Time: 07:48 PM Aug 24, 2022
|
|
|Message: example comment or post or reply
|
|
|
|
The event id of this event is 6c1.
|
|
|
|
When the UI asks for an event id, you can just enter 6c1, and press enter. Then the program will find the most recent event in its memory
|
|
with this prefix as its id, and send a reply/like to it. It is possible that some other event has the same 3 letter prefix, and is printed
|
|
later than your own event, in which case a different event will get a reply/like. But the odds of that happening are very low if the event
|
|
you are replying to is not too old.
|
|
|
|
To ensure that you reply to the exact right event id, invoke the program with --prefix N, where N is a large number. Then the program will
|
|
display the first N letters of each event, and you can reply to a longer ID. N can be as large as 64.
|
|
|
|
*

|
|
|
|
|
EXAMPLES
|
|
--------
|
|
|
|
To get ALL the latest messages for last 3 days (on linux bash which allows backtick execution):
|
|
|
|
\$ nostr_console.exe --request=`echo "[\\"REQ\\",\\"l\\",{\\"since\\":\$(date -d \\'-3 day\\' +%s)}]"`
|
|
|
|
To get the latest messages for user with private key K ( that is also used to sign posted/sent messages):
|
|
|
|
\$ nostr_console.exe --prikey=K
|
|
|
|
To get the latest messages for user with private key K for last 4 days ( default is 1) from relay R:
|
|
|
|
\$ nostr_console.exe --prikey=K --relay=R --days=4
|
|
|
|
To write events to a file ( and later read from it too), for any given private key K:
|
|
|
|
\$ nostr_console.exe --file=eventsFile.txt --prikey=K
|
|

|
|
|
KNOWN ISSUES
|
|
------------
|
|
|
|
* Does not get all the events, or in other words, does not properly get all the events from their own relays, and thus misses some events.
|
|
* Does not work on Tor network
