common arguments¶
Some arguments are used in many commands. This page describe them.
profile¶
profile arguments are really common, they allow you to select your profile.
If you don’t select any, the default profile is used, which is the first
profile created or the one you have explicitly set. You can check which profile
is used by default with li profile default
.
The common arguments for profile are:
-p PROFILE, --profile PROFILE
to select the name of your profile. It can be a profile key like
@DEFAULT@
-c, --connect
connect the profile to the XMPP server before doing anything else. If your profile is already connected, nothing happen. This is specially useful in scripts.
--start-session
starts a session without connecting, this can be needed if you can’t connect but you need to access your session e.g. to change parameters. This is advanced used and is not need in most common cases.
--pwd PASSWORD
the password of your profile, needed if the session is not started yet.
Note
using the --pwd
option is not secure if you are not the only user of your machine:
the password will appear IN CLEAR in the list of launched processes, or in the
history of your shell. If the profile password is needed and not specified, it will be
prompted (with echo disabled). If you are on a shared machine or if anybody can access
your shell history at some point, you should either connect first your profile with an
other frontend (Primitivus for instance), or avoid the --pwd
option and use the
prompt instead.
pubsub¶
pubsub arguments are used in many commands, they allow you to select a service, node and items. Depending on the command, you may only not be able to select an item, or you may select one or multiple items.
The common arguments for pubsub are:
-u PUBSUB_URL, --pubsub-url PUBSUB_URL
retrieve pubsub information from an URL. You can use either and
xmpp:
scheme or anhttps:
(orhttp:
) scheme. In the later case, the HTML page will be downloaded to retrieve the location of the XMPP node/item, if available. Note that you can override parts of the location in the URL if you specify service, node or item.e.g.:
$ li blog get -u https://www.goffi.org
-s SERVICE, --service
used to specifiy the JID of the pubsub service
-n NODE, --node NODE
used to specifiy the pubsub node
-i ITEM, --item ITEM
for commands where an item can be specified, you do it with this option. In some commands, multiple items can be specified, in this case just use this arguments several times.
-L, --last-item
when an item id is needed, you can use this option to retrieve the last published item. e.g.:
$ li blog edit --last-item
-M, --max-items
use to specify a maxium number of items to retrieve, when it makes sense. Note that this is using the pubsub max (i.e. defined in XEP-0060). Modern pubsub services should implement Result Set Management (RSM) and in this case the
-m, --max
argument should be prefered. See below for RSM common arguments.-C, --no-cache
skip pubsub cache. By default, internal pubsub cache is used automatically if requested items are available there. With this option set, a request to the pubsub service will always be done, regardless of presence of node items in internal cache.
result set management¶
Result Set Management (RSM) common arguments are used to navigate into pages of results when lot of elements may be expected. Given a result with a large number of arguments, a page is set of elements which correspond to an index (a page number). For instance if you have 123 elements, you can ask them 10 by 10, and index 1 match elements from 11 to 20 included.
-a ITEM_ID, --after ITEM_ID
find page after this item. You usually use the last item id of the latest page you got.
-b ITEM_ID, --before ITEM_ID
find page before this item. This this usually used when you check items backwards
--index RSM_INDEX
index of the page to retrieve. Note that first page has index 0.
-m RSM_MAX, --max RSM_MAX
used to specify a maxium number of items to retrieve per page. Note that the actual maximum number of items per page used may be lower if the service used consider that your request is too big.
message archive management¶
Message Archive Management (MAM) argument is used by some commands (related to instant message or pubsub) to filter results.
There is currently only one argument in this group:
-f FILTER_NAME VALUE, --filter FILTER_NAME VALUE
specify a MAM filter to use. Depending on the service supporting MAM, some filters can be used to do things like full text search. The available filters depend on the service you use, please check documentation of your service.
order-by¶
Order-By argument specify how the returned elements are sorted.
There is currently only one argument in this group:
-o {creation,modification}, --order-by {creation,modification}
specify how result is sorted. with
creation
, first created element is returned first. There is no notion of creation of modification in original pubsub XEP, as publishing an item with an existing id will overwrite the older one, creating a new item. With this option, we use the terms defined in XEP-0413, and creation time is the time when the first item has been published, before being overwritten.In the case of
modification
, if an item is overwritten, it reappears on top, this is the default pubsub sorting order.
progress¶
This single option may be used when a long operation is happening, like a file transfer.
-P, --progress
Show progress bar.
verbose¶
--verbose, -v
Add a verbosity level (can be used multiple times). Use to have more concise output by default when it makes sense.
draft¶
Common arguments used when an edition is potentially long to do, and a file may be kept until publication.
-D, --current
Used when you have started to edit something (e.g. a blog post), which is not yet published, and you want to continue your work.
e.g.:
$ li blog edit -D
-F DRAFT_PATH, --draft-path DRAFT_PATH
Used when you have started to edit something and want to continue your work from this file. In other words, it’s similar to
-D, --current
except that you specify the file to use instead of using the last available draft.
output¶
Output is used when you want to get the result of the command in a specific way. It may be used, for instance, to retrieve the result formatted in JSON so the data can be easily manipulated by a script, or if you want only a specific element of the result.
-O {…}, --output {…}
specify the output to use. Available options depends of the command you are using, check
li [your command] --help
to know them.e.g.:
$ li blog get -O json
--output-option OUTPUT_OPTS, --oo OUTPUT_OPTS
depending of the output selected, you may have options to customise the output. For instance, if you use the
template
output, you may use an option to display the result in a browser.e.g.:
$ li blog
Some options expect parameters, in this case they can be specified using
=
.e.g. specifying a template to use:
$ li blog get -O template --oo browser --oo template=/tmp/my_template.html
Time Pattern¶
When a command expect a date or date with time argument, you can use a “time pattern” (you
usually see the TIME_PATTERN
as name of the argument in --help
message when it can
be used).
This is a flexible way to enter a date, you can enter a date in one of the following way:
the string
now
to indicate current date and time;an absolute date using an international format. The parser know many formats (please check dateutil package documentation to have a detail of supported formats). Please note that days are specified first and that if no time zone is specified, the local time zone of your computer is assumed;
a relative date (or “relative delta”), see below for details on how to construct it;
a reference time (
now
or absolute date as above) followed by a relative delta. If the reference time is not specified,now
is used;
Time pattern is not case sensitive.
Relative Delta¶
A relative delta is specified with:
an optional direction
+
for times after reference time or-
for time before reference time (defaulting to+
);a number for the quantity of units
a unit (e.g. seconds or minutes), see the bellow for details
the word
ago
which is same as using-
for direction (direction andago
can’t be used at the same time)
Time Units¶
The singular or plural form of following units can be used:
s
,sec
,second
m
,min
,minute
h
,hr
,hour
d
,day
w
,week
mo
,month
y
,yr
,year
