tdl is a lightweight program for managing a 'to-do' list of pending jobs that you have.
It supports the following features :
This section discusses installation
The procedure for installing tdl from source code is as follows:
gunzip < tdl-1.0.tar.gz | tar xvf -
cd tdl-1.0
tdl does not use a ./configure mechanism (yet!) to configure options.
You have to manually edit Makefile. The variables you may want to edit are
CC
CFLAGS
prefix
/usr/local or /usr, unless you use a
stow or stow-like approach, or are building a distribution package.
INC_READLINE
readline.h and history.h can be
found. Note that a readline subdirectory is assumed to be suffixed onto
whatever path you define.
LIB_READLINE
libreadline and
libhistory can be found.
make
make install
This assumes you have the makeinfo and tex tools on your path.
make docs
Currently, there are no Makefile targets for this. Pick the documentation formats you want to keep and install them manually to the appropriate places.
For building a Slackware package, you could follow the steps above except for the installation
vi Makefile
make
make docs
mkdir pkg
make install DESTDIR=./pkg
(copy appropriate docs into subdirectories of pkg)
cd pkg
makepkg tdl.tgz
Packagers for other distributions may be able to adapt this. (The point the
example is making is that Makefile contains support for using a variable
DESTDIR in this way.)
An example spec file for RedHat packaging is in the file
tdl.spec.sample.
This section contains examples of using tdl.
This section shows how you can get started with tdl.
Let's assume you have a working directory for a project, and you want to
maintain a to-do list for things you need to do on that project. Let's assume
the working directory for the project is /home/foobar/myproject. Then
you'd start by entering the following commands into your shell:
% cd /home/foobar/myproject
% tdl create
Now, lets say you have some tasks to keep track of:
% tdl
tdl> add "Write user guide"
tdl> add "Write release notes"
tdl> add "Fix bug where empty data file causes core dump"
tdl> exit
%
The above sequence will add 3 tasks to your newly created database. A few days later, you might come back to the project and think "Hmmm. What did I need to do next?" You can enter
% tdl list
1 Write user guide
2 Write release notes
3 Fix bug where empty data file causes core dump
%
This shows another feature of tdl. If you pass a sub-command (and its
arguments, if any) on the tdl command line, tdl will execute just that command,
and return you to your shell prompt. However, if you run tdl with no
arguments, it will go into its interactive mode. For a single command like
list in this situation, you'd probably find the direct method
quicker.
Suppose you fix the bug. Then you could enter
% tdl done 3
after which the list command would only show the first two tasks as still being open, like this:
% tdl list
1 Write user guide
2 Write release notes
%
The add, list and done commands may be all that
you need in some cases. However, another useful command is report,
which will summarise all the tasks you completed in a given period. For
example, you could list everything you completed in the last 7 days like this
% tdl report 7d
- Fix bug where empty data file causes core dump
%
The other commands in tdl are mostly to do with changing the order of tasks in the database, assigning them priorities, and so on.
tdl has a set of functions that can be accessed in two different ways:
In the 'direct' method, the function and its arguments are provided on the command line. This mode is useful if you only want to perform a single operation. An example
% tdl add "A task"
%
The 'interactive' method is entered when the tdl command is run with no arguments. In this mode, many tdl operations may be performed within a single run of the program. This avoids loading and saving the database for each operation, which may have a small performance benefit. However, if the program is compiled with the readline library, the <tab> key will provide various completion functions. An example
% tdl
tdl> add "A task"
tdl> exit
%
When in interactive mode, these methods can be used to exit and return to the shell:
exit command (see exit command)
quit command (see quit command). Caution: this
does not save the modified database back to the disk. Only use it if you want
to discard all changes made in this tdl run.
This section describes each of the tdl subcommands.
The above command is one of the commands used for re-ordering the
entries in the database. The above and before commands are
synonymous.
The arguments of the above comamnd are:
tdl> above <index_to_insert_above> <index_to_move> ...
The first argument is the index of the entry above which the other entries are to be moved. The entries corresponding the 2nd index onwards will be placed in argument order above the first entry.
An example:
tdl> list
1 Task A
2 Task B
3 Task C
4 Task D
tdl> above 1 2 4 3
tdl> list
1 Task B
2 Task D
3 Task C
4 Task A
tdl>
You can move entries between levels in the hierarchy, with the restriction that you cannot move a node so that its new parent would be a descendent of itself.
If you want to move entries to the end of the list (i.e. above the bottom of the list), you can use a zero as the index of the reference entry, for example
tdl> list
1 Task A
1.1 Task A_A
1.2 Task A_B
2 Task B
3 Task C
tdl> above 1.0 3 2
tdl> list
1 Task A
1.1 Task A_A
1.2 Task A_A
1.3 Task C
1.4 Task B
tdl>
The add command is run as follows
tdl> add [@datespec] [parent-index] [priority] "Text for node"
In the simplest case of adding a new top-level entry to the database, with normal priority, starting now, this could be
tdl> add "Wash the dog"
In a more complex case, to add a high priority entry underneath entry index 1, with the new entry coming live at 11a.m. next Friday, this would be
tdl> add @+fri-11 1 hi "Wash the dog"
If you have several entries to add at once, you can go into an add mode. Enter a blank line to get back to the tdl> prompt.
tdl> add
add> Wash the dog
add> Wash the car
add>
tdl>
To add an entry direct from your shell, there is an additional shortcut (assuming the appropriate symbolic link was created during the installation process):
% tdla "Wash the dog"
%
The after and below commands are synonymous. See the
description of below (see below command).
The above and before commands are synonymous. See the
description of above (see above command).
The below command is one of the commands used for re-ordering the
entries in the database. The below and after commands are
synonymous.
The arguments of the below command are:
tdl> below <index_to_insert_below> <index_to_move> ...
The first argument is the index of the entry below which the other entries are to be moved. The entries corresponding the 2nd index onwards will be placed in argument order above the first entry.
An example:
tdl> list
1 Task A
2 Task B
3 Task C
4 Task D
tdl> below 4 2 1 3
tdl> list
1 Task D
2 Task B
3 Task A
4 Task C
tdl>
You can move entries between levels in the hierarchy, with the restriction that
you cannot move a node so that its new parent would be a descendent of itself.
This is similar to the description for the above command
(see above command).
The clone command can be used to make a deep copy of one or more
entries and add them as new top-level entries in the database. You might use
this if you have a task with a set of subtasks, and find that the same subtasks
apply to some new task. You could copy the first task, and edit the new
top-level task to change its text.
The arguments of the clone command are:
tdl> clone <index_to_clone> ...
An example is:
tdl> list
1 Wash things
1.1 Car
1.2 Dog
tdl> clone 1
tdl> edit 2 "Polish things"
tdl> list
1 Wash things
1.1 Car
1.2 Dog
2 Polish things
2.1 Car
2.2 Dog
If you want the cloned entries to be children of an existing entry, use the
copyto command (see copyto command).
The copyto command is very similar to the clone command
(see clone command). The difference is that copyto inserts the
newly created entries as children of an existing entry, rather than making them
new top level entries.
The arguments of the copyto command are:
tdl> copyto <new_parent_index> <index_to_clone> ...
An example is:
tdl> list
1 Household jobs
1.1 Wash things
1.1.1 Car
1.1.2 Dog
tdl> copyto 1 1.1
tdl> edit 1.2 "Polish things"
The create command can only be used direct from the shell command
line. It is not supported when tdl is used in its interactive
mode.1
Usually, the create command will create a new .tdldb file in
the current directory. However, if the TDL_DATABASE environment
variable is set when tdl is run, the path specified by that variable
will be used instead and the database will be created there. In both
cases, the create command will refuse to over-write an
existing database; an error message will be generated if that is
attempted.
% tdl create
The defer command is used to modify the start-time of one or more existing entries. Its argument structure is
tdl> defer @<datespec> <entry_index>[...] ...
where the @ on the datespec is optional because the argument is
required, although the @ can be included for consistency with other
commands where a datespec is optional.
An example of use is
tdl> defer @+fri 1 2.1... 5
which defers entries 1, 2.1 and all its children, and 5 until the following Friday.
To list deferred entries, use list -p.
To defer entries indefinitely, see postpone command.
To re-activate deferred or postponed entries, see open command.
This command is synonymous with the remove command (see remove command).
The argument structure is
delete <entry_index>[...] ...
The done command is run as follows
done [@<datespec>] <entry_index>[...] ...
The done command is used to mark one or more tasks as completed. Any
number of task indices may be specified.
The effects are as follows:
list command without the -a option).
If the string "..." is appended to an index, it means that entry and all its descendents. This provides a quick way to mark a whole sub-tree of tasks as being completed.
No entry may be marked 'done' if it has any children that are still 'open'
(i.e. not marked 'done'). (The ... form of the command marks the
deepest entries first to bypass this.)
The edit command is used to modify the text of an existing entry.
Its argument structure is
tdl> edit <entry_index> [<new_text>]
A single <entry-index> must be given. If <new-text> is provided, this replaces the text describing the specified entry. If no <new-text> is provided, you will be prompted with the old text to edit interactively. (This is only useful if the GNU readline library has been linked in.)
An examples follows.
To change the text for the entry with index 1,
tdl> edit 1 "New description"
tdl> list
1 Wash the dog
tdl> edit 1
edit (1)> Wash the dog (edit 'dog' to 'cat')
tdl> list
1 Wash the cat
tdl>
(Note, in earlier versions, edit could be used to change the
start-time of one or more entries. This is now handled by the defer
command (see defer command).)
The exit command is used to exit from tdl when it is used in
interactive mode. The exit command is not available in the command
line mode, where it would not make sense. An example:
tdl> exit
%
The exit command writes any pending updates to the database before
exiting. (Compare the quit command (see quit command), which
loses all updates made during the current tdl run.)
The export command is run as follows
export <filename> <entry_index> ...
It is used to export one or more tasks (and their subtasks) to another tdl database file. Perhaps you were keeping all your projects' to-do lists in one combined file, and decide you want to separate the list for a particular project.
An example would be
tdl> list
1 Tasks for project X
2 Tasks for project Y
2.1 Write manual
2.2 Write release notes
tdl> export /home/foobar/project_y/.tdldb 2.1 2.2
tdl> remove 2...
tdl> exit
The help command displays help information. When run without
arguments, a list of valid commands is produced. Note, this list is slightly
different depending on whether the help command is used through the
interactive readline interface or straight from the shell.

Description
Add a new entry to the database
Synopsis
add [@<datespec>] [<parent_index>] [<priority>] <entry_text>
<index> : 1, 1.1 etc (see output of 'tdl list')
<priority> : urgent|high|normal|low|verylow
<datespec> : [-|+][0-9]+[shdwmy][-hh[mm[ss]]] OR
[-|+](sun|mon|tue|wed|thu|fri|sat)[-hh[mm[ss]]] OR
[[[cc]yy]mm]dd[-hh[mm[ss]]]
<text> : Any text (you'll need to quote it if >1 word)
tdl>
The help command is synonymous with the usage command.
The ignore command puts one or more entries into an ignored
state. It is actually implemented in the same way as marking them as
done, but as though they were done a very long time ago. Thus,
ignored entries will be deleted by any subsequent purge operation.
I added this feature because, when applying remove to several
entries, I kept getting tripped up by the indices changing below the entry that
was removed (I kept removing the wrong entries later by not using the revised
indices). Instead, I can ignore them and rely on a periodic
purge to clean up the database.
Another use for the ignore command would be to move moribund entries into a wastebasket to stop them cluttering up the normal listing, but without removing them entirely in case you need to reprieve them later.
The ignore command is run as follows
ignore <entry_index>[...] ...
An example is
ignore 20 21.6.3 25... 28.1
If you need to un-ignore an entry, just undo it (see undo command).
The import command is used as follows:
import <filename>
This command is used to merge entries from the TDL database filename
into the default database (i.e. the one that most of the other commands would
be accessing).
You might use this command if you had a number of separate TDL databases, and wanted to merge their entries to form one combo database.
The into command is used to make one or more entries into sub-entries
of another entry. Its usage is
into <new_parent_index> <index_to_move> ...
The following example shows it use
tdl> list
1 Task A
2 Task B
3 Task C
4 Task D
tdl> into 1 3 2
tdl> list
1 Task A
1.1 Task C
1.2 Task B
2 Task D
tdl>
The into command is closely related to above,
after, before and below. In fact the following
three commands are equivalent
tdl> into N <indices> ...
and
tdl> above N.0 <indices> ...
and
tdl> before N.0 <indices> ...
The list command is used to display the tasks in the database. Its argument structure is:
list [-v] [-a] [-m] [-p] [-1..9]
[<min-priority>]
[<parent_index>|<search_condition>...]
When run with no arguments, the list contains all tasks that are
The arguments have the following functions:
-v
-a
-p
-m
If you always want this option, set the TDL_LIST_MONOCHROME environment
variable to any value. If this variable exists, a monochrome listing will be
generated.
-1, -2, ..., -9
-1 argument, only the first-level entries in the database are
shown. Sub-entries of these are shown by summary totals. See below for an
example.
<min-priority>
normal are shown in the list. If you specify this option,
tasks of at least the specified priority are shown. The values you can use are
urgent, high, normal, low or verylow. Each
can be abbreviated to just its initial letter.
<parent_index...>
When you specify indices, the behaviour regarding priority changes. If no
<min-priority> argument was given, the priority of a sub-entry must be
at least that of the entry with the given index for it to be shown. This is
most useful when the entire sub-tree has a lower than normal priority.
If you use the -1 ... -9 options with this option, the depth is
counted relative to the depth of the indexed node that you specify.
<search_condition>
Each search condition takes one of the following forms
/substring
/substring/1
In each case, an entry will match if substring is actually a substring
of the text of that entry. In the second form (where the number may be 0, 1, 2
or 3), a match occurs if there are up to that many errors in the substring. An
error is a single character inserted, removed or changed.
This option is most useful if you have a large database and can remember you have an entry somewhere containing particular word(s), but can't remember where it is.
If you need regular expression matching, the best approach would be to run
tdll from the shell and pipe the output to grep. The
internal matching does approximate matches with keys up to 31 characters.
The command is best illustrated by examples. Suppose the database contains these entries
1 bibble
1.1 zzzz
1.1.1 (DONE) yyyy
1.1.2 wwww
2 wibble
2.1 xxxx
3 wubble
where wibble and xxxx have priority low. The following
examples show the list command's behaviour.
tdl> list
1 bibble
1.1 zzzz
1.1.2 wwww
3 wubble
(Entry 2 and its child are omitted due to priority. Entry 1.1.1 is omitted because it is done.)
1 bibble
1.1 zzzz
1.1.1 (DONE) yyyy
1.1.2 wwww
2 wibble
2.1 xxxx
3 wubble
(Passing these arguments shows the missing entries)
tdl> list -1
1 [1/1] bibble
3 wubble
(The list is limited to top level entries. The [1/1] indices that entry
1 has 1 open child out of a total of 1 children.)
tdl> list -1 1.1
1.1 [1/2] zzzz
(This lists the 1.1 subtree, showing that there is 1 open child out of a total of 2 children.)
tdl> list /ww
1.1.2 wwww
tdl> list /ww/1
1.1.2 wwww
3 wubble
tdl>
(In the first case the substring ww must occur exactly in the entry's
text. In the second case, the string wu in wubble matches
ww with a single error so a match occurs.)
This is synonymous with the list command (see list command). It
is provided for people who are too used to typing ls in their shell.
The log command is very similar to the add command, except
that it immediately marks the new entry as done.It is the equivalent of using
add followed by done on the new entry. It is run as follows:
log [@<datespec>] [<parent_index>] [<priority>] <entry_text>
You might use the log command if complete a new task immediately but
want to make sure you log it for use in producing your weekly report (using
the report command, See report command.)
If you have several entries to add at once, you can go into an log mode. Enter a blank line to get back to the tdl> prompt.
tdl> log
log> Wash the dog
log> Wash the car
log>
tdl>
To add an entry direct from your shell, there is an additional shortcut (assuming the appropriate symbolic link was created during the installation process):
% tdlg "Wash the dog"
%
(the ending g on the shortcut was chosen as the final letter of the word
log. The shortcut tdll was already allocated for the
list subcommand.)
The moveto and into commands are synonymous. See the
description of into (see into command).
The narrow command can be used to limit the effects of later commands
to operate within a particular sub-tree of your database. Because the indices
you specify for the later operations have the common prefix omitted, this can
save typing if you have many changes to make within the same subtree.
The usage of the narrow command is
narrow <new_root_index>
The following example illustrates:
tdl> add a
tdl> add b
tdl> add -1 c
tdl> add -1 d
tdl> add -1 e
tdl> list
1 a
2 b
2.1 c
2.2 d
2.3 e
tdl> narrow 2
tdl[2]> list
2 b
2.1 c
2.2 d
2.3 e
tdl[2]> done 1 2
tdl[2]> list
2 b
2.3 e
tdl[2]> widen
tdl>
If your listings are in colour, the common prefix is coloured in blue whilst the paths below the root of the sub-tree are shown in the usual green. (In monochrome mode, there is no distinction.)
Whilst your view is narrowed, the index of the sub-tree root is shown in square
brackets between tdl and > (i.e. [2] in the example
above).
If you want to operate on the sub-tree root entry itself whilst you are
narrowed, you can use . to specify its index (think: current directory
in Unix.)
To reverse the effects of the narrow command, use the widen
command (see widen command).
This command is only available when tdl is being run interactively,
i.e. when you have a tdl prompt. It is not available directly from the
shell (where it wouldn't make much sense).
The open command is used to reverse the effect of the defer
command (see defer command) and postpone command (see postpone command). Its effect is actually to set the arrival time of the entries to
the current time.
The open command is used as follows
open <index_to_reopen>[...] ...
An example is
open 20 21... 25.2
The postpone command is used to make 1 more more entries postponed
indefinitely. Its effect is actually to set the arrival time of the entries a
long way in the future (i.e. it's an extreme form of the 'deferred' feature
available in the add and defer commands.) Postponed entries
can be re-activated with the open command (see open command).
The postpone command is used as follows
postpone <index_to_postpone>[...] ...
An example is
postpone 20 21... 25.2
To postpone an entry until a specific time in the future, use the
defer command (see defer command).
The priority command is used to modify the priority of one or more entries. Its argument structure is
priority <new_priority> <entry_index>[...] ...
The new_priority argument is the new priority to be assigned. The
values you can use are urgent, high, normal, low or
verylow. Each can be abbreviated to just its initial letter.
You can specify at least one entry_index. If an index is followed by
..., the whole sub-tree under the referenced entry will be modified too.
For example,
tdl> priority high 2 4.1...
will modify the priority of entry 2, entry 4.1, and all the entries under 4.1, to high.
The purge command is used to remove outdated done tasks from the
database. For example, you might want to automatically remove everything you
completed more than 2 months ago.
Its argument structure is
purge <since_datespec> [<ancestor_index> ...]
The since_datespec argument specifies a date. All entries which were
marked 'done' before this date will be completely removed from the database.
The default is to scan the entire database for done tasks that meet the date constraint. You may specify one or more indices to limit the behaviour. In this case, only the sub-trees headed by these indices will be considered for purge.
An example:
tdl> purge -2m 3.1 5
will purge all entries underneath entries 3.1 and 5 which were marked 'done' more than 2 months ago.
The quit command is used to exit from tdl when it is used in
interactive mode. The quit command is not available in the command
line mode, where it would not make sense. An example
tdl> quit
%
The quit command DOES NOT write any pending updates to the database before
exiting. (Compare the exit command (see exit command), which
does write all updates made during the current tdl run.)
The main use for the quit command would be to avoid damaging the
database if a serious error had been made.
The remove command is used to remove entries from the database. It
differs from purge see purge command in that there is no date constraint,
and entries do not have to be marked 'done' to be removed. You might use
remove if an open tasks no longer needs to be performed.
The argument structure is
remove <entry_index>[...] ...
You can specify one or more entry indices to remove. If an index is followed
by ..., tdl will remove the whole sub-tree based at that index.
You cannot remove an entry that has sub-entries below it. (The ...
handling for indices removes the deepest entries first to bypass this.)
An example:
tdl> remove 1.5.4 19... 20
will remove entries 1.5.4 and 20, as well as everything whose index starts with 19.
The remove command acts immediately to remove the specified entries
from the database. A less aggressive command with similar effects is
ignore (see ignore command).
The delete command (see delete command) is provided as a synonmym
for the remove command.
The report command is used to show entries that were marked 'done'
within a specific time interval. Its argument structure is
report <start_datespec> [<end_datespec>]
One or two date specifications may be given. If only the start_datespec is provided, the end_datespec defaults to the present time. The format of both arguments is described separately. See Datespec.
For example, suppose you have to write a report on what you have done in the last week. You could use
tdl> report 1w
The report is produced in a tree structure, mirroring the database structure.
Entries which have 'done' children, but which haven't themselves been marked
done, have their text surrounded by [[ and ]]. For example
tdl> list -a
1 bibble
1.1 zzzz
1.1.1 (DONE) yyyy
1.1.2 wwww
2 wibble
2.1 xxxx
tdl> report 1w
- [[bibble]]
- [[zzzz]]
- yyyy
You could cut-and-paste this text into your report, as a starting point that you can reformat into a report. Alternatively, if you run the command direct from the shell prompt line, you can redirect the output to a file,
% tdl report 1w > report.txt
%
The revert command discards any changes made in the session and
reloads the in-memory database from disc. If you have used the save
command (see save command) in the session, the database will revert to its
state at the most recent save. Otherwise it will revert to its state
when tdl was initially run.
The revert command does not take any arguments.
The save command can be used to write the current in-memory database
out to the disc database file. The behaviour is currently equivalent to the
command exit followed by re-running tdl from the shell.
This command is useful if you tend to do long interactive tdl sessions. It guards against the risks of
quit when you meant exit
tdl in another window and seeing a stale copy of the database file.
The save command does not take any arguments.
The undo command reverses the action of the done command
see done command. You can use it to re-open entries, e.g. if you marked
them 'done' by mistake.
Its argument structure is
undo <entry_index>[...] ...
You can specify one or more indices to act on. If an index is suffixed by
..., tdl will re-open the entire sub-tree based at that index.
The usage command is synonymous with the help command.
See help command.
The version command shows the program version.
tdl> version
tdl V1.1
tdl>
The which command displays the name of the current database file that
tdl is using. An example:
tdl> which
./.tdldb
tdl>
This command reverses the effects of the narrow command
(see narrow command).
Its usage is:
tdl> widen [<n_levels>]
The optional n_levels parameter tells tdl how many levels to widen the
view. If the parameter is not specified, it defaults to 1. If you try to
widen more levels than the depth of the current sub-tree root node, the
widening will be silently limited to its depth.
This command is only available when tdl is being run interactively,
i.e. when you have a tdl prompt. It is not available directly from the
shell (where it wouldn't make much sense).
If the TDL_DATABASE environment variable is set, its value is taken to be the name of the database to use. This allows for two distinct modes of use:
./.tdldb),
you will always use a database in the current working directory.
If this environment variable is not set, tdl finds the database by searching up
through the directory tree until it finds a file called .tdldb. The
idea is to allow for one database per project, by placing the database in the
parent directory of the project. Then as long as your current working
directory is anywhere within the project tree, the database will be found
during the search.
The only exception to this is the create command, which always
operates in the current directory (unless TDL_DATABASE is set, in which
case this variable's value defines the path to use.)
If you wish to share databases between directory trees in some other way, the recommended method is to use symbolic (or hard) links to make a single database appear to be in more than one directory.
When tdl has been compiled to use the readline library, the interactive mode supports a number of completion functions, activated with the <tab> key.
In particular, the following are supported:
help or usage is
already in the buffer, a list of commands will be shown(as above). The
<tab> completion works in the same way to complete the name of the command
you want a help summary for.
list or priority is
at the start of the input buffer and the current word starts with a letter, tdl
will try to complete the name of a priority level if <tab> is pressed.
done is at the start of the
input buffer, hitting <tab> will show a list of task indices that are still
open. If part of an index has already been typed, the open task indices for
which the typed characters are a prefix will be shown.
postpone is at the start of
the input buffer, hitting <tab> will show a list of tasks that may be
postponed. Tasks marked done are excluded. If open is at the
start of the input buffer, hitting <tab> will show a list of tasks that may
be opened.

In the 'all-numeric' format, the rule is that dates can have fields omitted from the start (assumed to be the current value), and times can have fields omitted from the end (assumed to be zero, except if the hours figure is missing it is assumed to be 12, since most work is done in the day.)
In the 'weekday and time' format, the time rule is the same: missing minutes and seconds are taken as zero and missing hours as 12. If the weekday is the same as today, the offset is always 7 days in the required direction. If the weekday is not the same as today, the offset will always be less than 7 days in the required direction.
In the 'relative' format, when a time is included as well, the procedure is as follows. First the time is determined which is the given number of hours, days etc away from the current time. Then the specified time on that day is used. The main use for this is to specify times like '8am yesterday'. Obviously some of the possible uses of this mode are rather far-fetched.
For the weekday and relative formats, the sign is actually optional. The default sign (implying past (-) or future (+)) will then be assumed depending on the command as shown below:
| Command | Default | Reason
|
| add | + | Add entries with deferred start times
|
| edit | + | Add entries with deferred start times
|
| defer | + | Modify start times of entries
|
| done | - | Entries have been completed at some time in the past
|
| log | - | Entries have been completed at some time in the past
|
| report | - | Reporting on earlier completed tasks not future ones
|
| purge | - | Tasks won't be completed in the future, so no need to purge future ones

Whenever tdl writes a modified database to disk, it renames the previous
database by adding .bak on the end of the filename. Thus .tdldb
is renamed to .tdldb.bak.
If you need to restore the previous .tdldb for any reason (e.g. a gross
mistake during editing, or if a bug causes it to be corrupted), you can
manually rename .tdldb.bak to .tdldb.
Indices may usually be specified as negative values. This counts from the end of the list. The commonest use for this is to add children to an entry you've just typed, e.g.
tdl> add "Parent entry"
tdl> add -1 "Child entry"
tdl> add -1 "Child entry"
tdl> add -1.-1 "Grandchild entry"
There is one example where negative indices are not handled in the usual way.
This is with the list command (see list command). Here, a
negative index could be misinterpreted as a depth option. If you really want
negative indices for the list command, terminate the options with
-- before providing indices and search patterns.
