11.2 #compiler-settings

Syntax:

#compiler-settings
key = value    (no quotes)
#end compiler-settings

#compiler-settings reset

The #compiler-settings directive overrides Cheetah's standard settings, changing how it parses source code and generates Python code. This makes it possible to change the behaviour of Cheetah's parser/compiler for a certain template, or within a portion of the template.

The reset argument reverts to the default settings. With reset, there's no end tag.

Here are some examples of what you can do:

$myVar
#compiler-settings
cheetahVarStartToken = @
#end compiler-settings
@myVar
#compiler-settings reset
$myVar

## normal comment
#compiler-settings
commentStartToken = //
#end compiler-settings

// new style of comment

#compiler-settings reset

## back to normal comments

#slurp
#compiler-settings
directiveStartToken = %
#end compiler-settings

%slurp
%compiler-settings reset

#slurp

Here's a partial list of the settings you can change:

  1. syntax settings
    1. cheetahVarStartToken
    2. commentStartToken
    3. multilineCommentStartToken
    4. multilineCommentEndToken
    5. directiveStartToken
    6. directiveEndToken
  2. code generation settings
    1. commentOffset
    2. outputRowColComments
    3. defDocStrMsg
    4. useNameMapper
    5. useAutocalling
    6. reprShortStrConstants
    7. reprNewlineThreshold
The meaning of these settings and their default values will be documented in the future.
