The
dicttool package enhances the standard dict
command with several new commands. In addition, the package
also defines several "creature comfort" list
commands as well. Each command checks to see if a command
already exists of the same name before adding itself, just
in case any of these slip into the core.
ladd varname args
This command will add a new instance of each element in args to varname, but only if that element is not already present.
ldelete varname args
This command will delete all instances of each element in args from varname.
dict getnull args
Operates like dict get, however if the key args does not exist, it returns an empty list instead of throwing an error.
dict print dict
This command will produce a string representation of dict, with each nested branch on a newline, and indented with two spaces for every level.
dict is_dict value
This command will return true if value can be interpreted as a dict. The command operates in such a way as to not force an existing dict representation to shimmer into another internal rep.
rmerge args
Return a dict which is the product of a recursive merge of all of the arguments. Unlike dict merge, this command descends into all of the levels of a dict. Dict keys which end in a : indicate a leaf, which will be interpreted as a literal value, and not descended into further.
set items [dict
merge {
option {color {default: green}}
} {
option {fruit {default: mango}}
} {
option {color {default: blue} fruit {widget: select values:
{mango apple cherry grape}}}
}]
puts [dict print $items]
Prints the following result:
option {
color {
default: blue
}
fruit {
widget: select
values: {mango apple cherry grape}
}
}
This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category dict of the Tcllib Trackers [http://core.tcl.tk/tcllib/reportlist]. Please also report any ideas for enhancements you may have for either package and/or documentation.
When proposing code changes, please provide unified diffs, i.e the output of diff -u.
Note further that attachments are strongly preferred over inlined patches. Attachments can be made by going to the Edit form of the ticket immediately after its creation, and then using the left-most button in the secondary navigation bar.
