clikan.shcommand line kanban
This shell script provides an interactive command line interface for manipulating files with Markdown formatted lists.
Each list item corresponds to a card of a simple kanban system.
The three possible list bullets
-*+ are used as indicators of
status "wait/backlog", "doing", and "done/archived".
The script permits displaying and status changes of the items, addition of new "waiting" items, direct edition of the lists ("kanban" files) and of the configuration file defining kanbans and some script parameters.
In addition, it will display as "doing" each list item of the
- ...(MM-DD)... where
MM-DD corresponds to the
current month and day.
Only the script
clikanban.sh must be installed somewhere,
where it can be executed either directly, or as argument to
sh or another reasonable shell. Currently no arguments are
The script currently requires the standard (POSIX conformal)
sed grep ed cat mktemp cp date for correct function;
they should be available on any sane UNIX-like system.
The script will check for a configuration file and if necessary create one (see Configuration further below). It will scan the defined "kanban files" for "doing" items (with preceding '* ') and display them, then wait for input after a prompt.
A help screen is displayed if an empty command is given, and
then also the configuration can be displayed by entering
q: quit the program (also CTRL-D should work)
d: display all "doing" entries as selection list
a: display all "archived/done" entries as selection list
w: display all "waiting/backlog" entries as selection list
doN : change card to "doing/active" status
doneN : change card to "archive/done" status and append a timestamp of format "// YY-MM-DD"
waitN : change card to "waiting/backlog" status
n: add a new item/card to the target kanban (only one line of text); content may be given on the same line, separated by whitespace
k: define target kanban file (for direct edition, and new items)
ek: directly edit the target kanban file with the text editor
ec: directly edit the configuration file with the text editor
!: execute arguments with shell,
/bin/sh -cby default (set
myshellvariable in source to
echoto deactivate this)
In the list above, "N" is a number from the last displayed selection list;
if none is given, the script asks for one. The numbers are not attributed
to specific "cards" but to the items in the last displayed selection list
(i.e the first "doing" and the first "waiting" card both have number 1,
and it depends on the selection context, which one is referred to).
do/done/wait also accept several number arguments
separated by white space.
Be careful with the
ek and the
ec commands, as the syntax of the
corresponding files must be preserved for the script to correctly work.
Whitespace in general is no problem, though.
Cards/items do not have any kind of ID number; they are just text, and
therefore some strange things may happen if the same entry exists in
more than one "kanban file" — in particular, they will all change
status (doing/waiting/done) together.
No card may contain TAB characters; they are replaced by SPC at entry.
Do not add TAB charactes manually through the
ek command, as this
will probably disturb the script's manipulation of such cards.
d command will not only display items with a preceding
but also those with a pattern of
(MM-DD) anywhere after preceding
-*+ characters, with
MM being the current month and
current day. This permits to use a "kanban file" as a calendar; in
that case it should be given as last
kanban entry, to prevent
filling of the screen with calendar entries when using any of the
d w a commands (see also example below).
In addition, the
d command will sort the output cards according
to the configuration variable
sortdir (see below).
! "shell escape" command will allow you to execute shell commands.
If the command begins with a letter and does not match to an internal
clikan command, you may even omit the leading
! — so be careful:
/bin/rm -rf * at the clikan prompt if you absolutely
know what you're doing! You've been warned!
(Also note commands are of course executed in a subshell,
cd .. is rather pointless.)
The script expects a configuration file named by the environment
$CLIKANCONF or (if undefined)
$HOME/.clikanconf by default.
If there isn't any, the script generates a new one, populated
with all possible parameters at reasonable default values, and
also creates an item list ("kanban file") with the name
$HOME/clikanban.md containing some dummy entries.
Please see the source or the generated configuration file for information about possible settings!
$HOME/clikanban.md already exists, the script will
save a backup copy as
$HOME/clikanban.md.bak in case
something went wrong with the configuration file.
In addition, it uses the contents of
when needing to launch a text editor, or
ed as default.
(Because, what else!?)
We assume a first start with no environment variables set.
$ ./clikan.sh no config found, generating default config file /home/username/.clikanconf and default kanban file /home/username/clikanban.md (this should happen only once at first use) doing 1: learn to use clikan
Default config and kanban files have been generated. Let's see the waiting, the archived/done, and again the "doing" cards:
|< w waiting/todo/backlog 1: improve clikan |< a archived/done 1: install clikan |< d doing 1: learn to use clikan
Now let's assume we know everything, so card 1 is done:
|< done 1 doing |< w waiting/todo/backlog 1: improve clikan
Obviously there is work waiting, so let's do it:
|< do 1 doing 1: improve clikan
Now we check for the target kanban ...
|< k 1: /home/username/clikanban.md choice? (default: /home/username/clikanban.md) doing 1: improve clikan
... do a manual editing session on it ...
|< ek calling /bin/ed /home/username/clikanban.md ... 158 1z # my kanban file + learn to use clikan * improve clikan + install clikan ### titles work as comments # might be a future card you don't yet want in waiting
... change one entry ...
?improve * improve clikan s/improve/test/p * test clikan
... and save it, quit, and we're back at our script:
w 155 q welcome back
Verifying the entry indeed has been changed:
|< d doing 1: test clikan
Now let's add a new card:
|< n enter new card for target /home/username/clikanban.md : give feedback to clikan developer doing 1: test clikan
The new card has been added to the waiting/backlog list:
|< w waiting/todo/backlog 1: give feedback to clikan developer
We could also have given the card content as direct argument, by typing
n give feedback... at the prompt.
Just hitting RETURN at the prompt shows the help/usage page:
|< ./clikan.sh : command line kanban (2020-01-03/HB9KNS) configuration file: /home/username/.clikanconf for help about commands, just hit RETURN to show configuration, enter 'c'
We want to see the configuration, then quit:
