NAME

6       khal - khal Documentation
7
8       Khal  is  a  calendar  program for the terminal for viewing, adding and
9       editing events and calendars. Khal is build on the iCalendar  and  vdir
10       (allowing the use of vdirsyncer(1) for CalDAV compatibility) standards.
11

USAGE

13       Khal  offers a set of commands, most importantly list, calendar, inter‐
14       active, new, printcalendars, printformats, and search. See below for  a
15       description  of  what every command does. Calling khal without any com‐
16       mand will invoke the default command, which can  be  specified  in  the
17       configuration file.
18
19   Options
20       khal  (without any commands) has some options to print some information
21       about khal:
22
23       --version
24              Prints khal's version number and exits
25
26       -h, --help
27              Prints a summary of khal's options and commands and then exits
28
29       Several options are common to almost all of khal's commands (exceptions
30       are described below):
31
32       -v     Be more verbose (e.g. print debugging information)
33
34       -c CONFIGFILE
35              Use an alternate configuration file
36
37       -a CALENDAR
38              Specify  a calendar to use (which must be configured in the con‐
39              figuration file), can be used several times. Calendars not spec‐
40              ified will be disregarded for this run.
41
42       -d CALENDAR
43              Specify  a  calendar which will be disregarded for this run, can
44              be used several times.
45
46       --color/--no-color
47              khal will detect if standard output is not a tty, e.g., you  re‐
48              direct  khal's  output  into  a file, and if so remove all high‐
49              lighting/coloring from its output. Use --color if  you  want  to
50              force  highlighting/coloring and --no-color if you want coloring
51              always removed.
52
53       --format FORMAT
54              For all of khal's commands that print events, the formatting  of
55              that  event can be specified with this option.  FORMAT is a tem‐
56              plate string, in which identifiers  delimited  by  curly  braces
57              ({}) will be expanded to an event's properties.  FORMAT supports
58              all  formatting  options  offered   by   python's   str.format()
59              <https://docs.python.org/3/library/string.html#formatstrings>
60              (as it is used internally).  The available template options are:
61
62              title  The title of the event.

94
95              repeat-symbol
96                     A repeating symbol (loop arrow) if the event  is  repeat‐
97                     ing.

101
102              description-separator
103                     A separator: " :: " that appears when there is a descrip‐
104                     tion.
105
106              location
107                     The event location.
108

114
115              start-style
116                     The start time in timeformat OR an appropriate symbol.
117
118              to-style
119                     A hyphen "-" or nothing such that it  appropriately  fits
120                     between start-style and end-style.
121
122              end-style
123                     The end time in timeformat OR an appropriate symbol.
124
125              start-end-time-style
126                     A  concatenation  of start-style, to-style, and end-style
127                     OR an appropriate symbol.
128
129              end-necessary
130                     For an allday event this is an empty  string  unless  the
131                     end  date  and start date are different. For a non-allday
132                     event this will show the time  or  the  datetime  if  the
133                     event start and end date are different.
134
135              end-necessary-long
136                     Same as end-necessary but uses datelong and datetimelong.
137
138              status The  status  of  the event (if this event has one), some‐
139                     thing like CONFIRMED or CANCELLED.
140
141              cancelled
142                     The string CANCELLED (plus one blank) if the event's sta‐
143                     tus is cancelled, otherwise nothing.
144
145              By default, all-day events have no times. To see a start and end
146              time anyway simply add -full to the end  of  any  template  with
147              start/end,  for  instance start-time becomes start-time-full and
148              will always show start and end times (instead of being empty for
149              all-day events).
150
151              In  addition, there are colors: black, red, green, yellow, blue,
152              magenta, cyan, white (and their bold versions: red-bold,  etc.).
153              There  is  also reset, which clears the styling, and bold, which
154              is the normal bold.
155
156              For example the below command with print the title and  descrip‐
157              tion of all events today.
158
159                 khal list --format "{title} {description}"
160
161       --day-format DAYFORMAT
162              works  similar  to --format, but for day headings. It only has a
163              few options (in addition to all the color options):
164
165              date   The date in dateformat.
166
167              date-long
168                     The date in longdateformat.
169
170              name   The date's name (Monday, Tuesday,…) or today or tomorrow.
171
172              If the --day-format is passed an empty string then it  will  not
173              print  the  day  headers (for an empty line pass in a whitespace
174              character).
175
176   dates
177       Almost everywhere khal accepts dates, khal  should  recognize  relative
178       date  names  like today, tomorrow and the names of the days of the week
179       (also in three letters abbreviated form). Week  day  names  get  inter‐
180       preted  as the date of the next occurrence of a day with that name. The
181       name of the current day gets interpreted as that date next  week  (i.e.
182       seven days from now).
183
184   Commands
185   list
186       shows  all  events scheduled for a given date (or datetime) range, with
187       custom formatting:
188
189          khal list [-a CALENDAR ... | -d CALENDAR ...] [--format FORMAT]
190          [--day-format DAYFORMAT] [--once] [--notstarted] [START [END | DELTA] ]
191
192       START and END can both be given as dates, datetimes or times (it is as‐
193       sumed  today  is meant in the case of only a given time) in the formats
194       configured in the configuration file.  If END is not given, midnight of
195       the start date is assumed. Today is used for START if it is not explic‐
196       itly given.  If DELTA, a (date)time range in the format I{m,h,d}, where
197       I  is  an integer and m means minutes, h means hours, and d means days,
198       is given, END is assumed to be START + DELTA.  A value of eod  is  also
199       accepted  as DELTA and means the end of day of the start date. In addi‐
200       tion, the DELTA week may be used to specify that the  daterange  should
201       actually be the week containing the START.
202
203       The --once option only allows events to appear once even if they are on
204       multiple days. With the --notstarted option only events are shown  that
205       start after START.
206
207   at
208       shows all events scheduled for a given datetime. khal at should be sup‐
209       plied with a date and time, a time (the date is then assumed to be  to‐
210       day)  or  the string now. at defaults to now. The at command works just
211       like the list command, except it has an implicit end time of zero  min‐
212       utes after the start.
213
214          khal at [-a CALENDAR ... | -d CALENDAR ...] [--format FORMAT]
215          [--notstarted] [[START DATE] TIME | now]
216
217   calendar
218       shows a calendar (similar to cal(1)) and list. khal calendar should un‐
219       derstand the following syntax:
220
221          khal calendar [-a CALENDAR ... | -d CALENDAR ...] [START DATETIME]
222          [END DATETIME]
223
224       Date selection works exactly as for khal list. The  displayed  calendar
225       contains  three  consecutive months, where the first month is the month
226       containing the first given date. If today  is  included,  it  is  high‐
227       lighted.  Have a look at khal list for a description of the options.
228
229   configure
230       will  help users creating an initial configuration file. configure will
231       refuse to run if there already is a configuration file.
232
233   import
234       lets the user import .ics files with the following syntax:
235
236          khal import [-a CALENDAR] [--batch] [--random-uid|-r] ICSFILE
237
238       If an event with the same UID is already present  in  the  (implicitly)
239       selected  calendar khal import will ask before updating (i.e. overwrit‐
240       ing) that old event with the imported one,  unless  --batch  is  given,
241       than  it  will always update. If this behaviour is not desired, use the
242       --random-uid flag to generate a new, random UID.   If  no  calendar  is
243       specified  (and  not  --batch), you will be asked to choose a calendar.
244       You can either enter the number printed behind each calendar's name  or
245       any unique prefix of a calendar's name.
246
247   interactive
248       invokes the interactive version of khal, can also be invoked by calling
249       ikhal. While ikhal can be used entirely with the  keyboard,  some  ele‐
250       ments respond if clicked on with a mouse (mostly by being selected).
251
252       When the calendar on the left is in focus, you can
253
254          • move through the calendar (default keybindings are the arrow keys,
255            space and backspace, those keybindings  are  configurable  in  the
256            config file)
257
258          • focus on the right column by pressing tab or enter
259
260          • re-focus on the current date, default keybinding t as in today
261
262          • marking  a  date  range, default keybinding v, as in visual, think
263            visual mode in Vim, pressing esc escape this visual mode
264
265          • if in visual mode, you can select the other end of  the  currently
266            marked range, default keybinding o as in other (again as in Vim)
267
268          • create  a new event on the currently focused day (or date range if
269            a range is selected), default keybinding n as in new
270
271          • search for events, default keybinding /, a  pop-up  will  ask  for
272            your search term
273
274       When an event list is in focus, you can
275
276          • view  an  event's details with pressing enter (or tab) and edit it
277            with pressing enter (or tab) again  (if  [default]  event_view_al‐
278            ways_visible  is  set  to  True, the event in focus will always be
279            shown in detail)
280
281          • toggle an event's deletion status,  default  keybinding  d  as  in
282            delete,  events  marked for deletion will appear with a D in front
283            and will be deleted when khal exits.
284
285          • duplicate the selected event, default keybinding p as in duplicate
286            (d was already taken)
287
288          • export the selected event, default keybinding e
289
290       In the event editor, you can
291
292       • jump  to  the  next  (previous)  selectable element with pressing tab
293         (shift+tab)
294
295       • quick save, default keybinding meta+enter (meta will probably be alt)
296
297       • use some common editing  short  cuts  in  most  text  fields  (ctrl+w
298         deletes  word  before cursor, ctrl+u (ctrl+k) deletes till the begin‐
299         ning (end) of the line, ctrl+a (ctrl+e) will jump  to  the  beginning
300         (end) of the line
301
302       • in the date and time field you can increment and decrement the number
303         under the cursor with ctrl+a and ctrl+x (time in 15 minute steps)
304
305       • activate actions by pressing enter on text enclosed by angled  brack‐
306         ets, e.g.  < Save > (sometimes this might open a pop up)
307
308       Pressing esc will cancel the current action and/or take you back to the
309       previously shown pane (i.e. what you see when you open ikhal),  if  you
310       are at the start pane, ikhal will quit on pressing esc again.
311
312   new
313       allows  for adding new events. khal new should understand the following
314       syntax:
315
316          khal new [-a CALENDAR] [OPTIONS] [START [END | DELTA] [TIMEZONE] SUMMARY
317          [:: DESCRIPTION]]
318
319       where start- and enddatetime are either datetimes, times,  or  keywords
320       and  times in the formats defined in the config file. If no calendar is
321       given via -a, the default calendar is used. new does not support -d and
322       also -a may only be used once.
323
324       new  accepts  these combinations for start and endtimes (specifying the
325       end is always optional):
326
327datetime [datetime|time] [timezone]
328
329time [time] [timezone]
330
331date [date]
332
333       where the formats for datetime and time are as follows:
334
335datetime =  (longdatetimeformat|datetimeformat|keyword-date  time‐
336            format)
337
338time = timeformat
339
340date = (longdateformat|dateformat)
341
342       and  timezone,  which  describes  the timezone the events start and end
343       time are in, should be a valid Olson DB identifier (like  Europe/Berlin
344       or  America/New_York.  If  no timezone is given, the defaulttimezone as
345       configured in the configuration file is used instead.
346
347       The exact format  of  longdatetimeformat,  datetimeformat,  timeformat,
348       longdateformat  and  dateformat  can be configured in the configuration
349       file.  Valid keywords for dates are today, tomorrow, the  English  name
350       of  all seven weekdays and their three letter abbreviations (their next
351       occurrence is used).
352
353       If no end is given, the default length of one  hour  or  one  day  (for
354       all-day events) is used. If only a start time is given the new event is
355       assumed to be starting today. If only a time is given for the event  to
356       end  on, the event ends on the same day it starts on, unless that would
357       make the event end before it has started, then the next day is used  as
358       end date
359
360       If a 24:00 time is configured (timeformat = %H:%M) an end time of 24:00
361       is accepted as the end of a given date.
362
363       If the summary contains the string ::, everything after :: is taken  as
364       the description of the new event, i.e., the "body" of the event (and ::
365       will be removed).
366
367       Passing the option --interactive (-i) makes all arguments optional  and
368       interactively  prompts  for  required  fields,  then  the  event may be
369       edited, the same way as in the edit command.
370
371   Options
372-l, --location=LOCATION specify where this event will be held.
373
374-g, --categories=CATEGORIES specify which categories this  event  be‐
375         longs  to.   Comma separated list of categories. Beware: some servers
376         (e.g. SOGo) do not support multiple categories.
377
378-r, --repeat=RRULE specify if and how this event should be recurring.
379         Valid values for RRULE are daily, weekly, monthly and yearly
380
381-u, --until=UNTIL specify until when a recurring event should run
382
383--alarm  DURATION  will add an alarm DURATION before the start of the
384         event, DURATION should look like 1day 10minutes or 1d3H10m,  negative
385         DURATIONs will set alarm after the start of the event.
386
387   Examples
388          khal new 18:00 Awesome Event

405       curs every week.
406
407   edit
408       an interactive command for editing and deleting events using  a  search
409       string
410
411          khal edit [--show-past] event_search_string
412
413       the  command will loop through all events that match the search string,
414       prompting the user to delete, or change attributes.
415
416   printcalendars
417       prints a list of all configured calendars.
418
419   printformats
420       prints a fixed date (2013-12-21 10:09)  in  all  configured  date(time)
421       formats.   This  is supposed to help check if those formats are config‐
422       ured as intended.
423
424   search
425       search for events matching a search string and print them.   Currently,
426       search  will  print  one line for every different event in a recurrence
427       set, that is one line for the master event, and one line for every dif‐
428       ferent  overwritten  event.   No advanced search features are currently
429       supported.
430
431       The command
432
433          khal search party
434
435       prints all events matching party.
436

CONFIGURATION

438       khal reads configuration files in the ini  syntax,  meaning  it  under‐
439       stands  keys separated from values by a =, while section and subsection
440       names are enclosed by single or double square brackets (like  [section‐
441       name] and [[subsectionname]]).
442
443   Help with initial configuration
444       If  you  do  not  have a configuration file yet, running khal configure
445       will launch a small, interactive tool that should help you with initial
446       configuration of khal.
447
448   Location of configuration file
449       khal is looking for configuration files in the following places and or‐
450       der: $XDG_CONFIG_HOME/khal/config (on  most  systems  this  is  ~/.con‐
451       fig/khal/config),  ~/.khal/khal.conf  (deprecated)  and  a  file called
452       khal.conf in the current directory (deprecated).  Alternatively you can
453       specify  which configuration file to use with -c path/to/config at run‐
454       time.
455
456   The [calendars] section
457       The [calendars] section is mandatory and must contain at least one sub‐
458       section.   Every  subsection  must  have a unique name (enclosed by two
459       square brackets).  Each subsection needs exactly one path setting,  ev‐
460       erything else is optional.  Here is a small example:
461
462          [calendars]
463
464            [[home]]
465              path = ~/.calendars/home/
466              color = dark green
467
468            [[work]]
469              path = ~/.calendars/work/
470              readonly = True
471
472
473       color  khal  will  use  this  color for coloring this calendar's event.
474              The following color names are supported:  black,  white,  brown,
475              yellow,  dark  gray,  dark  green,  dark blue, light gray, light
476              green, light blue, dark magenta, dark cyan, dark red, light  ma‐
477              genta, light cyan, light red.  Depending on your terminal emula‐
478              tor's settings, they might look different than what  their  name
479              implies.   In  addition to the 16 named colors an index from the
480              256-color palette or a 24-bit color code can be  used,  if  your
481              terminal supports this.  The 256-color palette index is simply a
482              number between 0 and 255.  The 24-bit color  must  be  given  as
483              #RRGGBB,  where  RR, GG, BB is the hexadecimal value of the red,
484              green and blue component, respectively.   When  using  a  24-bit
485              color,  make  sure to enclose the color value in ' or "!  If the
486              color is set to auto (the default), khal tries to read the  file
487              color from this calendar's vdir, if this fails the default_color
488              (see below) is used. If color is set to '', the default_color is
489              always used.
490
491                 type   color
492
493                 default
494                        auto
495
496       path   The  path  to an existing directory where this calendar is saved
497              as a vdir.  The directory is searched for  events  or  birthdays
498              (see type). The path also accepts glob expansion via * or ? when
499              type is set to discover.  This allows for paths  such  as  ~/ac‐
500              counts/*/calendars/*,  where  the  calendars  directory contains
501              vdir directories. In addition, ~/calendars/* and ~/calendars/de‐
502              fault  are valid paths if there exists a vdir in the default di‐
503              rectory. (The previous behavior of recursively searching  direc‐
504              tories has been replaced with globbing).

511       readonly
512              setting  this to True, will keep khal from making any changes to
513              this calendar

519
520       type   Setting the type of this collection (default calendar).
521
522              If set to calendar (the default), this collection will  be  used
523              as a standard calendar, that is, only files with the .ics exten‐
524              sion will be considered, all other files are ignored (except for
525              a possible color file).
526
527              If  set to birthdays khal will expect a VCARD collection and ex‐
528              tract birthdays from those VCARDS, that is only files with  .ics
529              extension  will  be considered, all other files will be ignored.
530              birthdays also implies readonly=True.
531
532              If    set    to    discover,    khal    will    use     globbing
533              <https://en.wikipedia.org/wiki/Glob_(programming)>   to   expand
534              this calendar's path to (possibly) several paths and  use  those
535              as  individual calendars (this cannot be used with birthday col‐
536              lections`). See Exemplary discover usage for an example.
537
538              If an individual calendar vdir has a color file, the  calendar's
539              color will be set to the one specified in the color file, other‐
540              wise the color from the calendars subsection will be used.

794              this  timezone  will be used for new events (when no timezone is
795              specified) and when khal does not understand the timezone speci‐
796              fied in the icalendar file.  If no timezone is set, the timezone
797              your computer is set to will be used.

853              by default khal uses some unicode symbols (as in 'non-ascii') as
854              indicators  for  things like repeating events, if your font, en‐
855              coding etc. does not support those symbols, set  this  to  False
856              (this will enable ascii based replacements).

897              events in a given time range, used for list, calendar and in in‐
898              teractive (ikhal). Please note, that any color styling  will  be
899              ignored in ikhal, where events will always be shown in the color
900              of the calendar they belong to.  The syntax is the same  as  for
901              --format.

921              Defines  the  behaviour  of  ikhal's  right column. If True, the
922              right column will show events for as many days  as  fit,  moving
923              the cursor through the list will also select the appropriate day
924              in the calendar column on the left. If False, only a fixed ([de‐
925              fault]  timedelta)  amount of days' events will be shown, moving
926              through events will not change the focus in the left column.

935              are  not clear through context, e.g. for search, used almost ev‐
936              erywhere but list and calendar. It is therefore probably a  sen‐
937              sible  choice to include the start- and end-date.  The syntax is
938              the same as for --format.

979              This  is very much work in progress. Help is really welcome! The
980              two currently available color schemes (dark and light)  are  de‐
981              fined in khal/ui/colors.py, you can either help improve those or
982              create a new one (see below). As ikhal uses urwid, have  a  look
983              at   urwid's  documentation  <http://urwid.org/manual/displayat
984              tributes.html> for how to set  colors  and/or  at  the  existing
985              schemes.  If  you cannot change the color of an element (or have
986              any other problems) please open an issue on github.
987
988              If you want to create your own color scheme, copy the  structure
989              of the existing ones, give it a new and unique name and also add
990              it as an option in khal/settings/khal.spec in the  section  [de‐
991              fault] of the property theme.

1018   Exemplary discover usage
1019       If you have the following directory layout:
1020
1021          ~/calendars
1022          ├- work/
1023          ├- home/
1024          └─ family/
1025
1026       where  work,  home  and family are all different vdirs, each containing
1027       one calendar, a matching calendar section could look like this:
1028
1029          [[calendars]]
1030          path = ~/calendars/*
1031          type = discover
1032          color = dark green
1033
1034   Syncing
1035       To get khal working with CalDAV you will first need to setup vdirsyncer
1036       <https://github.com/untitaker/vdirsyncer>.   After each start khal will
1037       automatically check if anything has changed  and  automatically  update
1038       its  caching  db (this may take some time after the initial sync, espe‐
1039       cially for large calendar collections).  Therefore, you might  want  to
1040       execute  khal  automatically  after  syncing  with vdirsyncer (e.g. via
1041       cron).
1042

STANDARDS

1044       khal tries to follow standards and  RFCs  (most  importantly  RFC  5545
1045       <https://tools.ietf.org/html/rfc5545.html>  iCalendar)  wherever possi‐
1046       ble. Known intentional and unintentional deviations are listed below.
1047
1048   RDATE;VALUE=PERIOD
1049       RDATE s with PERIOD values are currently not  supported,  as  icalendar
1050       <https://github.com/collective/icalendar>  does  not  support  it  yet.
1051       Please submit any real world examples of events with RDATE;VALUE=PERIOD
1052       you  might  encounter (khal will print warnings if you have any in your
1053       calendars).
1054
1055   RANGE=THISANDPRIOR
1056       Recurrent events with the RANGE=THISANDPRIOR are and will  not  be  [1]
1057       supported  by  khal,  as  applications  supporting  the latest standard
1058       <http://tools.ietf.org/html/rfc5546> MUST NOT create those.  khal  will
1059       print  a  warning  if  it encounters an event containing RANGE=THISAND‐
1060       PRIOR.
1061
1062       [1]  unless a lot of users request this feature
1063
1064   Events with neither END nor DURATION
1065       While the RFC states:
1066
1067          A calendar entry with a "DTSTART" property but no "DTEND"
1068          property does not take up any time. It is intended to represent
1069          an event that is associated with a given calendar date and time
1070          of day, such as an anniversary. Since the event does not take up
1071          any time, it MUST NOT be used to record busy time no matter what
1072          the value for the "TRANSP" property.
1073
1074       khal transforms those events into all-day events lasting  for  one  day
1075       (the  start  date).  As  long  a  those events do not get edited, these
1076       changes will not be written to the vdir (and with that  to  the  CalDAV
1077       server).  Any  timezone  information that was associated with the start
1078       date gets discarded.
1079
1080       NOTE:
1081          While the main rationale for this behaviour was laziness on part  of
1082          khal's main author, other calendar software shows the same behaviour
1083          (e.g. Google Calendar and Evolution).
1084
1085   Timezones
1086       Getting localized time right, seems to be the most difficult part about
1087       calendaring  (and messing it up ends in missing the one important meet‐
1088       ing of the week). So I'll briefly describe here, how khal tries to han‐
1089       dle  timezone information, which information it can handle and which it
1090       can't.
1091
1092       In general, there are two different type of  events.  Localized  events
1093       (with  localized  start and end datetimes) which have timezone informa‐
1094       tion attached to their start and end  datetimes,  and  floating  events
1095       (with  floating start and end datetimes), which have no timezone infor‐
1096       mation attached (all-day events, events that last for complete days are
1097       floating as well). Localized events are always observed at the same UTC
1098       <https://en.wikipedia.org/wiki/Coordinated_Universal_Time>  (no  matter
1099       what  time  zone the observer is in), but different local times. On the
1100       other hand, floating events are always observed at the same local time,
1101       which might be different in UTC.
1102
1103       In khal all localized datetimes are saved to the local database as UTC.
1104       Datetimes that are already UTC, e.g.  19980119T070000Z,  are  saved  as
1105       such, others are converted to UTC (but don't worry, the timezone infor‐
1106       mation does not get lost). Floating events get saved in floating  time,
1107       independently of the localized events.
1108
1109       If you want to look up which events take place at a specified datetime,
1110       khal always expects that you want to know what  events  take  place  at
1111       that local datetime. Therefore, the (local) datetime you asked for gets
1112       converted to UTC, the appropriate localized  events  get  selected  and
1113       presented  with  their  start and end datetimes converted to your local
1114       datetime. For floating events no conversion is necessary.
1115
1116       Khal (i.e. icalendar <https://github.com/collective/icalendar>) can un‐
1117       derstand   all   timezone   identifiers   as   used  in  the  Olson  DB
1118       <https://en.wikipedia.org/wiki/Tz_database> and custom timezone defini‐
1119       tions, if those VTIMEZONE components are placed before the VEVENTS that
1120       make use of them (as most calendar programs seem to do). In case an un‐
1121       known  (or  unsupported)  timezone  is found, khal will assume you want
1122       that event to be placed in the default timezone (which can  be  config‐
1123       ured in the configuration file as well).
1124
1125       khal  expects  you always want all start and end datetimes displayed in
1126       local time (which can be set in the configuration file as well,  other‐
1127       wise your computer's timezone is used).

FAQ

1130       Frequently asked questions:
1131
1132
1133
1134         start up of khal and ikhal is very slow
1135                In some case the pytz (python timezone) is only available as a
1136                zip file, as pytz accesses several parts during initialization
1137                this  takes  some  time.  If  time  python  -c  "import  pytz;
1138                pytz.timezone('Europe/Berlin')" takes nearly as much  time  as
1139                running  khal, uncompressing that file via pytz via (sudo) pip
1140                unzip pytz might help.

1146                You  probably  need to upgrade urwid to version 1.1.0, if your
1147                OS does come with an older version of urwid  you  can  install
1148                the  latest  version to userspace (without messing up your de‐
1149                fault installation) with pip install --upgrade urwid --user.
