This manual describes
calcurse functionalities, and how to use them. The
installation from source is first described, together with the available
command line arguments. The user interface is then presented, with all of the
customizable options that change
calcurse behavior. Last, bug reporting
procedure is explained, as well as the way one can contribute to
calcurse is a text-based calendar and scheduling application. It helps
keeping track of events, appointments and everyday tasks. A configurable
notification system reminds user of upcoming deadlines, and the curses based
interface can be customized to suit user needs. All of the commands are
documented within an online help system.
Frederic started thinking about this project when he was finishing his Ph.D. in
Astrophysics as it started to be a little hard to organize himself and he
really needed a good tool for managing his appointments and todo list.
Unfortunately, he finished his Ph.D. before finishing
calcurse but he
continued working on it, hoping it would be helpful to other people.
In mid-2010, Lukas took over development of
calcurse and is now the main
contributor and reviewer of patches.
calcurse anyway? Well, it is simply the concatenation of *cal*endar
and *curse*s, the name of the library used to build the user interface.
Calcurse is multi-platform and intended to be lightweight, fast and reliable.
It is to be used inside a console or terminal, locally or on a distant machine
within an ssh (or similar) connection.
Calcurse can be run in two different modes : interactive or non-interactive
mode. The first mode allows oneself to view its own personal organizer almost
everywhere, thanks to the text-based interface. The second mode permits to
easily build reminders just by adding
calcurse with appropriate command line
arguments inside a cron tab or within a shell init script.
calcurse was created with the end-user in mind, and tends to be as
friendly as possible. This means a complete on-line help system, together with
having all of the possible actions displayed at any time inside a status bar.
The user interface is configurable, and one can choose between several color
and layout combinations. Key bindings are also configurable, to fit everyone’s
needs. Last, a configurable notification system reminds user of upcoming
appointments. The reminders are sent even if the user’s interface is not
running, as calcurse is able to run in background.
Calcurse requires only a
C compiler, such as
gcc, and the
ncurses library. It would be very surprising not to have a valid
library already installed on your computer, but if not, you can find it at the
following url: http://ftp.gnu.org/pub/gnu/ncurses/
|It is also possible to link
calcurse supports internationalization (i18n hereafter) through the
gettext utilities. This means
calcurse can produce multi-lingual messages
if compiled with native language support (i.e. NLS).
However, NLS is optionnal and if you do not want to have support for
multi-lingual messages, you can disable this feature. This is done by giving
--disable-nls option to
configure (see section
Install process). To check if the
gettext utilities are
installed on your system, you can search for the
libintl.h header file for
$ locate libintl.h
If this header file is not found, then you can obtain the
gettext sources at
the following url : http://ftp.gnu.org/pub/gnu/gettext/
First you need to gunzip and untar the source archive:
$ tar zxvf calcurse-3.2.1.tar.gz
Once you meet the requirements and have extracted the archive, the install process is quite simple, and follows the standard three steps process:
$ ./configure $ make $ make install # (may require root privilege)
./configure --help to obtain a list of possible options.
Command line arguments
calcurse takes the following options from the command line (both short and
long options are supported):
Print the appointments and events for the current day and exit. The calendar from which to read the appointments can be specified using the
-c <file>, --calendar <file>
Specify the calendar file to use. The default calendar is
~/.calcurse/apts(see section calcurse files). This option has precedence over
-d <date|num>, --day <date|num>
Print the appointments for the given date or for the given number of upcoming days, depending on the argument format. Two possible formats are supported:
a date (possible formats described below).
In the first case, the appointment list for the specified date will be returned, while in the second case the appointment list for the
nupcoming days will be returned. As an example, typing
calcurse -d 3will display your appointments for today, tomorrow, and the day after tomorrow. Possible formats for specifying the date are defined inside the general configuration menu (see General options), using the
Note: as for the
-aflag, the calendar from which to read the appointments can be specified using the
-D <dir>, --directory <dir>
Specify the data directory to use. If not specified, the default directory is
Specify a format to control the output of appointments in non-interactive mode. See the Format strings section for detailed information on format strings.
Specify a format to control the output of recurrent appointments in non-interactive mode. See the Format strings section for detailed information on format strings.
Specify a format to control the output of events in non-interactive mode. See the Format strings section for detailed information on format strings.
Specify a format to control the output of recurrent events in non-interactive mode. See the Format strings section for detailed information on format strings.
Specify a format to control the output of todo items in non-interactive mode. See the Format strings section for detailed information on format strings.
Run the garbage collector for note files and exit.
Print a short help text describing the supported command-line options, and exit.
-i <file>, --import <file>
Import the icalendar data contained in
-l <num>, --limit <num>
Limit the number of results printed to num.
Print the next appointment within upcoming 24 hours and exit. The indicated time is the number of hours and minutes left before this appointment.
Note: the calendar from which to read the appointments can be specified using the
Print events and appointments for the num number of days and exit. If no num is given, a range of 1 day is considered.
Don’t save configuration nor appointments/todos.Warning
Use this this with care! If you run an interactive calcurse instance in read-only mode, all changes from this session will be lost without warning!
Print events and appointments from date and exit. If no date is given, the current day is considered.
When used with the
-tflag, print only the items having a description that matches the given regular expression.
Display the status of running instances of calcurse. If calcurse is running, this will tell if the interactive mode was launched or if calcurse is running in background. The process pid will also be indicated.
todolist and exit. If the optional number
numis given, then only todos having a priority equal to
numwill be returned. The priority number must be between 1 (highest) and 9 (lowest). It is also possible to specify
0for the priority, in which case only completed tasks will be shown.
calcurseversion and exit.
Export user data to specified format. Events, appointments and todos are converted and echoed to stdout. Two possible formats are available: ical and pcal (see section Links below). If the optional argument
formatis not given, ical format is selected by default.
Note: redirect standard output to export data to a file, by issuing a command such as:
$ calcurse --export > my_data.dat
Format strings are composed of printf()-style format specifiers — ordinary
characters are copied to stdout without modification. Each specifier is
introduced by a
% and is followed by a character which specifies the field to
print. The set of available fields depends on the item type.
Format specifiers for appointments
Print the start time of the appointment as UNIX time stamp
Print the start time of the appointment using the
Print the duration of the appointment in seconds
Print the end time of the appointment as UNIX time stamp
Print the end time of the appointment using the
Print the description of the item
Print the name of the note file belonging to the item
Print the note belonging to the item
Format specifiers for events
Print the description of the item
Print the name of the note file belonging to the item
Print the note belonging to the item
Format specifiers for todo items
Print the priority of the item
Print the description of the item
Print the name of the note file belonging to the item
Print the note belonging to the item
calcurse -r7 --format-apt='- %S -> %E\n\t%m\n%N'
Print appointments and events for the next seven days. Also, print the notes attached to each regular appointment (simulates
calcurse -r7 --format-apt=' - %m (%S to %E)\n' --format-recur-apt=' - %m (%S to %E)\n'
Print appointments and events for the next seven days and use a custom format for (recurrent) appointments: ` - Some appointment (18:30 to 21:30)`.
calcurse -t --format-todo '(%p) %m\n'
List all todo items and put parentheses around the priority specifiers.
Extended format specifiers
Extended format specifiers can be used if you want to specify advanced
formatting options. Extended specifiers are introduced by
%( and are
terminated by a closing parenthesis (
)). The following list includes all
short specifiers and corresponding long options:
(end) specifiers support strftime()-style extended
formatting options that can be used for fine-grained formatting. Additionally,
the special formats
epoch (which is equivalent to
default (which is mostly equivalent to
..:.. if the item doesn’t start/end at the current day) are
(duration) specifiers support a subset of the
strftime()-style formatting options, along with two extra qualifiers.
The supported options are
%S, and by default each
of these is zero-padded to two decimal places. To avoid the
- before the formatting option (for example,
E option will display the total number of time units
until the appointment, rather than showing the remaining number of time
units modulo the next larger time unit. For example, an appointment in
50 hours will show as 02:00 with the formatting string
%H:%M, but will
show 50:00 with the formatting string
%EH:%M. Note that if you are
E options, the

Environment variable for i18n
calcurse can be compiled with native language support (see
gettext library). Thus, if you wish to have
messages displayed into your native language, first make sure it is available
by looking at the
po/LINGUAS file. This file indicates the set of available
languages by showing the two-letters corresponding code (for exemple, fr
stands for french). If you do not find your language, it would be greatly
appreciated if you could help translating
calcurse (see the How to contribute? section).
If your language is available, run
calcurse with the following command:
$ LC_ALL=fr_FR calcurse
where fr_FR is the locale name in this exemple, but should be replaced by the locale corresponding to the desired language.
You should also specify the charset to be used, because in some cases the
accents and such are not displayed correctly. This charset is indicated at the
beginning of the po file corresponding to the desired language. For instance,
you can see in the fr.po file that it uses the iso-8859-1 charset, so you could
calcurse using the following command:
$ LC_ALL=fr_FR.ISO8859-1 calcurse
Other environment variables
The following environment variables affect the way

When called with at least one of the following arguments:
calcurse is started in non-interactive mode. This
means the desired information will be displayed, and after that,
simply quits and you are driven back to the shell prompt.
That way, one can add a line such as
calcurse --todo --appointment in its
init config file to display at logon the list of tasks and appointments
scheduled for the current day.
|Key bindings that are indicated in this manual correspond to the default
ones, defined when
When called without any argument or only with the

containing three different panels which you can browse using the
plus a notification bar and a status bar (see figure below).

The first panel represents a calendar which allows to highlight a particular day, the second one contains the list of the events and appointments on that day, and the last one contains a list of tasks to do but which are not assigned to any specific day.
Depending on the selected view, the calendar could either display a monthly (default as shown in previous figure) or weekly view. The weekly view would look like the following:
+------------------------------------+ | Calendar | |----------------------------(# 13)--| | Mon Tue Wed Thu Fri Sat Sun | | 29 30 31 01 02 03 04 | | <----+-- slice 1: 00:00 to 04:00 AM | -- -- -- -- -- -- | | <----+-- slice 2: 04:00 to 08:00 AM | -- -- -- -- -- -- | | <----+-- slice 3: 08:00 to 12:00 AM | - -- -- -- -- -- -- - <-+-- midday | <----+-- slice 4: 12:00 to 04:00 PM | -- -- -- -- -- -- | | <----+-- slice 5: 04:00 to 08:00 PM | -- -- -- -- -- -- | | <----+-- slice 6: 08:00 to 12:00 PM +------------------------------------+
The current week number is displayed on the top-right side of the panel (# 13 meaning it is the 13th week of the year in the above example). The seven days of the current week are displayed in column. Each day is divided into slices of 4 hours each (6 slices in total, see figure above). A slice will appear in a different color if an appointment falls into the corresponding time-slot.
In the appointment panel, one can notice the
(|) sign just in front of the
date. This indicates the current phase of the moon. Depending on which is the
current phase, the following signs can be seen:
- ` |) `
- ` (|) `
- ` (| `
- ` | `
- no sign
Phase of the moon does not correspond to any of the above ones.
At the very bottom of the screen there is a status bar, which indicates the possible actions and the corresponding keystrokes.
Just above this status bar is the notify-bar, which indicates from left to right : the current date, the current time, the calendar file currently in use (apts on the above example, which is the default calendar file, see the following section), and the next appointment within the upcoming 24 hours. Here it says that it will be lunch time in one hour and twenty minutes.
|Some actions, such as editing or adding an item, require to type in some text. This is done with the help of the built-in input line editor.|
Within this editor, if a line is longer than the screen width, a
< character is displayed in the last column indicating that there are more
character after, before and after, or before the current position,
respectively. The line is scrolled horizontally as necessary.
Moreover, some editing commands are bound to particular control characters.
Hereafter are indicated the available editing commands (

this subdirectory contains descriptions of the notes which are attached to appointments, events or todos. Since the file name of each note file is a SHA1 hash of the note itself, multiple items can share the same note file. calcurse provides a garbage collector (see the
-gcommand line parameter) that can be used to remove note files which are no longer linked to any item.

The import and export capabilities offered by
calcurse are described below.
Data in icalendar format as described in the rfc2445 specification (see links section below) can be imported into calcurse. Calcurse ical parser is based on version 2.0 of this specification, but for now on, only a subset of it is supported.
The following icalendar properties are handled by calcurse:
VTODOitems: "PRIORITY", "VALARM", "SUMMARY", "DESCRIPTION"
VEVENTitems: "DTSTART", "DTEND", "DURATION", "RRULE", "EXDATE", "VALARM", "SUMMARY", "DESCRIPTION"
DESCRIPTION property will be converted into calcurse format by
adding a note to the item. If a "VALARM" property is found, the item will be
flagged as important and the user will get a notification (this is only
applicable to appointments).
Here are the properties that are not implemented:
negative time durations are not taken into account (item is skipped)
some recurence frequences are not recognize: "SECONDLY" / "MINUTELY" / "HOURLY"
some recurrence keywords are not recognized (all those starting with
BY): "BYSECOND" / "BYMINUTE" / "BYHOUR" / "BYDAY" / "BYMONTHDAY" / "BYYEARDAY" / "BYWEEKNO" / "BYMONTH" / "BYSETPOS" plus "WKST"
the recurrence exception keyword "EXRULE" is not recognized
timezones are not taken into account
Two possible export formats are available:
pcal (see section
Links below to find out about those formats).
At any time, the built-in help system can be invoked by pressing the
By default, it shows an introduction to the help system in an external pager.
You need to exit the pager in order to get back to calcurse (pressing
should almost always work). The default pager can be changed by setting the
PAGER environment variable.
If you want to display help on a specific feature or key binding, type
:help add) or
:help <key> (e.g.
:help ^A) on the main
All of the
calcurse parameters are configurable from the Configuration menu
available when pressing
C. You are then driven to a submenu with five
possible choices : pressing
C again will lead you to the Color scheme
L allows you to choose the layout of the main
calcurse screen (in other words, where to put the three different panels on
G permits you to choose between different general options,
K opens the key bindings configuration menu, and last you can modify
the notify-bar settings by pressing
These options control
calcurse general behavior, as described below:
This option allows to automatically save the user’s data (if set to yes) when quitting. <p class="rq"><span class="valorise">warning:</span> No data will be automatically saved if
general.autosaveis set to no. This means the user must press
S(for saving) in order to retrieve its modifications.
Automatically run the garbage collector for note files when quitting.
If different from
0, user’s data will be automatically saved every general.periodicsave minutes. When an automatic save is performed, two asterisks (i.e.
**) will appear on the top right-hand side of the screen).
If set to yes, confirmation is required before quitting, otherwise pressing
calcurseto quit without prompting for user confirmation.
If this option is set to yes, pressing
Dfor deleting an item (either a todo, appointment, or event), will lead to a prompt asking for user confirmation before removing the selected item from the list. Otherwise, no confirmation will be needed before deleting the item.
Setting this option to no will result in skipping the system dialogs related to the saving and loading of data. This can be useful to speed up the input/output processes.
If set to no, this will cause the disappearing of the progress bar which is usually shown when saving data to file. If set to yes, this bar will be displayed, together with the name of the file being saved (see section calcurse files).
If set to
0, the monthly calendar view will be displayed by default otherwise it is the weekly view that will be displayed.
One can choose between Monday and Sunday as the first day of the week. If
general.firstdayofweekis set to monday, Monday will be first in the calendar view. Otherwise, Sunday will be the first day of the week.
This option indicates the format to be used when displaying dates in non-interactive mode. Using the default values, dates are displayed the following way: mm/dd/aa. You can see all of the possible formats by typing
man 3 strftimeinside a terminal.
This option indicates the format that will be used to enter dates in calcurse. Four choices are available:
One can define ones own key bindings within the
Keys configuration menu. The
default keys look like the one used by the
vim editor, especially the
displacement keys. Anyway, within this configuration menu, users can redefine
all of the keys available from within calcurse’s user interface.
To define new key bindings, first highlight the action to which it will apply. Then, delete the actual key binding if necessary, and add a new one. You will then be asked to press the key corresponding to the new binding. It is possible to define more than one key binding for a single action.
An automatic check is performed to see if the new key binding is not already set for another action. In that case, you will be asked to choose a different one. Another check is done when exiting from this menu, to make sure all possible actions have a key associated with it.
The following keys can be used to define bindings:
lower-case, upper-case letters and numbers, such as
CONTROL-key followed by one of the above letters
escape, horizontal tab, and space keys
arrow keys (up, down, left, and right)
While inside the key configuration menu, an online help is available for each one of the available actions. This help briefly describes what the highlighted action is used for.
|As of calcurse 3.0.0, displacement commands can be preceded by an
optional number to repeat the command. For example,
calcurse color theme can be customized to suit user’s needs. To change the
default theme, the configuration page displays possible choices for foreground
and background colors. Using arrows or calcurse displacement keys to move, and
X or space to select a color, user can preview the theme which will be
applied. It is possible to keep the terminal’s default colors by selecting the
corresponding choice in the list.
The chosen color theme will then be applied to the panel borders, to the titles, to the keystrokes, and to general informations displayed inside status bar. A black and white theme is also available, in order to support non-color terminals.
|Depending on your terminal type and on the value of the
The layout corresponds to the position of the panels inside
The default layout makes the calendar panel to be displayed on the top-right
corner of the terminal, the todo panel on the bottom-right corner, while the
appointment panel is displayed on the left hand-side of the screen (see the
figure in section Interactive mode for an
example of the default layout). By choosing another layout in the
configuration screen, user can customize
calcurse appearance to best suit his
needs by placing the different panels where needed.
The following option is used to modify the layout configuration:
Eight different layouts are to be chosen from (see layout configuration screen for the description of the available layouts).
The sidebar is the part of the screen which contains two panels: the calendar and, depending on the chosen layout, either the todo list or the appointment list.
The following option is used to change the width of the sidebar:
Width (in percentage, 0 being the minimum width) of the side bar.
The following options are used to modify the notify-bar behavior:
This option indicates if you want the notify-bar to be displayed or not.
format.notifydate(default: %a %F)
With this option, you can specify the format to be used to display the current date inside the notification bar. You can see all of the possible formats by typing
man 3 strftimeinside a terminal.
With this option, you can specify the format to be used to display the current time inside the notification bar. You can see all of the possible formats by typing
man 3 strftimeinside a terminal.
When there is an appointment which is flagged as
importantwithin the next
notification.warningseconds, the display of that appointment inside the notify-bar starts to blink. Moreover, the command defined by the
notification.commandoption will be launched. That way, the user is warned and knows there will be soon an upcoming appointment.
notification.command(default: printf \a)
This option indicates which command is to be launched when there is an upcoming appointment flagged as
important. This command will be passed to the user’s shell which will interpret it. To know what shell must be used, the content of the
$SHELLenvironment variable is used. If this variable is not set,
/bin/shis used instead.
$ calcurse --next | mail -s "[calcurse] upcoming appointment!" email@example.com
Invert the sense of flagging an appointment as
important. If this is enabled, all appointments will be notified - except for flagged ones.
If set to yes, daemon mode will be enabled, meaning
calcursewill run into background when the user’s interface is exited. This will allow the notifications to be launched even when the interface is not running. More details can be found in section Background mode.
If set to yes,
calcursedaemon activity will be logged (see section files).
Incorrect highlighting of items appear when using calcurse black and white
theme together with a
$TERM variable set to xterm-color. To fix this bug,
and as advised by Thomas E. Dickey (
xterm maintainer), xterm-xfree86 should
be used instead of xterm-color to set the
"The xterm-color value for $TERM is a bad choice for XFree86 xterm because it
is commonly used for a
terminfo entry which happens to not support bce. Use
the xterm-xfree86 entry which is distributed with XFree86 xterm (or the similar
one distributed with ncurses)."

How to contribute?
If you would like to contribute to the project, you can first send your
feedback on what you like or dislike, and if there are features you miss in
calcurse. For now on, possible contributions concern the translation of
calcurse messages and documentation.
|We recently dropped all translations of the manual files from the distribution tarball. There are plan to reintroduce them in form of a Wiki on the calcurse website. Please follow the mailing lists for up-to-date information.|
The doc/ directory of the source package already contains translated version
calcurse manual. However, if the manual is not yet available into your
native language, it would be appreciated if you could help translating it.
To do so, just copy one of the existing manual file to
XX identifies your language. Then translate this newly created file and send
it to the author (see Reporting bugs and feeback), so that it can be
included in the next
As already mentioned,
gettext utilities are used by
calcurse to produce
multi-lingual messages. We are currently using
Transifex to manage those translations.
This section provides informations about how to translate those messages into
your native language. However, this howto is deliberately incomplete, focusing
on working with
calcurse specifically. For more comprehensive
informations or to grasp the Big Picture of Native Language Support, you should
refer to the
GNU gettext manual at:
|Since we switched to Transifex, editing po files is not necessary
anymore as Transifex provides a user-friendly, intuitive web
interface for translators. Knowledge of
Basically, three different people get involved in the translation chain: coders, language coordinator, and translators. After a quick overview of how things work, the translator tasks will be described hereafter.
To be able to display texts in the native language of the user, two steps are required: internationalization (i18n) and localization (l10n).
i18n is about making
calcurse support multiple languages. It is performed by
coders, who will mark translatable texts and provide a way to display them
translated at runtime.
l10n is about making the i18n’ed
calcurse adapt to the specific language of
the user, ie translating the strings previously marked by the developers, and
setting the environment correctly for
calcurse to use the result of this
So, translatable strings are first marked by the coders within the
files, then gathered in a template file (calcurse.pot - the pot extension
meaning portable object template). The content of this template file is then
merged with the translation files for each language (fr.po for French, for
instance - with po standing for portable object, ie meant to be read and
edited by humans). A given translation team will take this file, translate its
strings, and send it back to the developers. At compilation time, a binary
version of this file (for efficiency reasons) will be produced (fr.mo - mo
stands for machine object, i.e. meant to be read by programs), and then
calcurse will use this file at runtime, translating the
strings according to the locale settings of the user.
Suppose someone wants to initiate the translation of a new language. Here are the steps to follow:
First, find out what the locale name is. For instance, for french, it is
fr_FR, or simply
fr. This is the value the user will have to put in his
LC_ALLenvironment variable for software to be translated (see Environment variable for i18n).
Then, go into the po/ directory, and create a new po-file from the template file using the following command:
msginit -i calcurse.pot -o fr.po -l fr --no-translatorIf you do not have
msginitinstalled on your system, simply copy the calcurse.pot file to fr.po and edit the header by hand.
Now, having this fr.po file, the translator is ready to begin.
The format of the po-files is quite simple. Indeed, po-files are made of four things:
location lines: tells you where the strings can be seen (name of file and line number), in case you need to see a bit of context.
msgid lines: the strings to translate.
msgstr lines: the translated strings.
lines prefixed with
#: comments (some with a special meaning, as we will see below).
Basically, all you have to do is fill the msgstr lines with the translation of the above msgid line.
A few notes:
- Fuzzy strings
You will meet strings marked with a
calcursewon’t use the translations of such strings until you do something about them. A string being fuzzy means either that the string has already been translated but has since been changed in the sources of the program, or that this is a new string for which
gettextmade a wild guess for the translation, based on other strings in the file. It means you have to review the translation. Sometimes, the original string has changed just because a typo has been fixed. In this case, you won’t have to change anything. But sometimes, the translation will no longer be accurate and needs to be changed. Once you are done and happy with the translation, just remove the
"#, fuzzy"line, and the translation will be used again in
- c-format strings and special sequences
Some strings have the following comment:
"#, c-format". This tells that parts of the string to translate have a special meaning for the program, and that you should leave them alone. For instance, %-sequences, like
"%s". These means that
calcursewill replace them with another string. So it is important it remains. There are also \-sequences, like
\t. Leave them, too. The former represents an end of line, the latter a tabulation.
- Translations can be wrapped
If lines are too long, you can just break them like this:
msgid "" "some very long line" "another line"
- po-file header
At the very beginning of the po-file, the first string form a header, where various kind of information has to be filled in. Most important one is the charset. It should resemble
"Content-Type: text/plain; charset=utf-8\n"
You should also fill in the Last-Translator field, so that potential contributors can contact you if they want to join you in the translation team, or have remarks/typo fixes to give about the translations. You can either just give your name/nick, or add an email address, for exemple:
"Last-Translator: Frederic Culot <firstname.lastname@example.org>\n"
Adding comments (lines begining with the
#character) can be a good way to point out problems or translation difficulties to proofreaders or other members of your team.
- Strings size
calcurseis a curses/console program, thus it can be heavily dependant on the terminal size (number of columns). You should think about this when translating. Often, a string must fit into a single line (standard length is 80 characters). Don’t translate blindly, try to look where your string will be displayed to adapt your translation.
- A few useful tools
The po-file format is very simple, and the file can be edited with a standard text editor. But if you prefer, there are few specialized tools you may find convenient for translating:

Uploading to Transifex
There’s several different ways to upload a finished (or semi-finished) translation for a new language to Transifex. The easiest way is to browse to the Translation Teams page and request the addition of a new team.
As soon as we accepted your request, you will be able to upload your po file on the calcurse resource page by clicking the Add translation button at the bottom.
You can also use a command line client to submit translations instead of having
to use the web interface every time you want to submit an updated version. If
you have a recent version of
setuptools installed, you can get the CLI client
by issuing the following command:
$ easy_install -U transifex-client
Alternatively, you can get the source code of transifex-client at http://pypi.python.org/pypi/transifex-client.
After you downloaded and installed the client, run the following commands in the calcurse source directory to checkout the translation resources of calcurse:
$ tx pull -a
To submit changes back to the server, use:
$ tx push -r calcurse.calcursepot -t -l <locale>
Using the Transifex web UI
As an alternative to editing po files, there is a web-based interface that can be used to create and update translations. After having signed up and created a new translation team (see Uploading to Transifex on how to do that), click the Add translation button at the bottom on the calcurse resource page, select the language you’d like to translate and choose Translate Online.
