Parses templateString for macros in the form [$%]{NAME} and finds the value corresponding to NAME if any.
The NAME string may contain any non-whitespace character execpt '}'
- Parameters
-
initialValues a map with the keys for the macros to expand. keys with a value are ignored. parentWindow is used if dialogs have to be shown
- Returns
- true if all macros was successfully expanded
- See also
- insertTemplateText for a list of supported macros

| bool TemplateInterface::insertTemplateText | ( | const Cursor & | insertPosition, |

| ) |
Inserts an interactive ediable template text at line "line", column "col".
- Returns
- true if inserting the string succeeded
Use insertTemplateText(lines(), ...) to append text at end of document Template strings look like "for( int ${index}=0;${index}<10;${index}++) { ${cursor} };" or "%{date}"
This syntax is somewhat similar to the one found in the Eclipse editor or textmate.
There are certain common placeholders (macros), which get assigned a default initialValue, If the second parameter does not a given value. For all others the initial value is the name of the placeholder.
Placeholder names may only consist of a-zA-Z0-9_
- Since
- 4.5 if a placeholder is a mirror, the place holder name may contain additional information ${something/regexp/replacement/} takes the value of the placeholder something and replaces the match with the replacement before inserting the mirrored value ${something/regexp/replacement/g} like above, but for all occurrences The syntax of the regexp and the replacement are the ones from kateparts regexp search/replace ${something/regexp/replacement/i} like above, but case insensitive The syntax of the regexp and the replacement are the ones from kateparts regexp search/replace Possible flags: g and i. Those flags can be combined too If a literal / should appear in the regexp, it has to be escaped \/, literal \ has to be escaped too
If you have mirrored ranges and want another occurrence than the first one as the master you can add @ directly after the placeholder name.
The interface2 version invokes the function specified by functionName within the script specified by the scriptToken, if a placeholder is specified with backticks like ${placeholderfunctionName} The function has a global environment containing "view", "document" and "debug", at least in the katepart implementation. The function invocation is not allowed to be mixed with other replacements
If a / or ` replacement is done on a master the initial value is modified and therefor also all mirrored placeholders are affected too, later on the replacement is not done anymore on master ranges
The parameters for invoked javascript functions will be the following: value of the master (or initial value), //to be done: placeholder name, small wrapper around the template handler (to do more sophisticated things, like adding additional placehlder points, aattaching custom properties for state keeping, ....) you tell
Specification of initial values You can specify initial values which are different from the placeholder name this is done via, this makes only sense for $ placeholders, not for % ${placeholder:some value} or ${placeholder@:some value} It is not allowed to mix : and / after the first colon, everything is interpreted as default value, } in the default value have to be escaped (backslashes before } have to be escaped themselves) and regexp searches are ignored. The : has to be directly after the placeholder name or after an optional @ symbol.
Common placeholders and values are
- index: "i"
- loginname: The current users's loginname
- firstname: The current user's first name retrieved from kabc
- lastname: The current user's last name retrieved from kabc
- fullname: The current user's first and last name retrieved from kabc
- email: The current user's primary email address retrieved from kabc
- date: current date
- time: current time
- year: current year
- month: current month
- day: current day
- hostname: hostname of the computer
- selection: The implementation should set this to the selected text, if any
- cursor: at this position the cursor will be after editing of the template has finished, this has to be taken care of by the actual implementation. The placeholder gets a value of "|" assigned.
If a macro is started with a % (persent sign) like "%{date}" it isn't added to the list editable strings ( for example TAB key navigation) if a value differing from the macro name is found.
If the editor supports some kind of smart indentation, the inserted code should be layouted by the indenter.

You must implement this, it is called by insertTemplateText, after all default values are inserted.
If you are implementing this interface, this method should work as described in the documentation for insertTemplateText above.
- Returns
- true if any text was inserted.
Implemented in KTextEditor::TemplateInterface2.

DO NOT USE !!!! THIS IS USED INTERNALLY by the interface only !!!!!! Behaviour might change !!!!!!!
