Unable to load xml file

Posted 18 years ago by Steven Liu

I am trying to define a simple language that only contains #IF and #ENDIF pre-processor directives, nothing else. the xml file is:


<SyntaxLanguage Key="TEST" LanguageDefinitionVersion="3.0" Secure="True" xmlns="http://ActiproSoftware/SyntaxEditor/3.0/LanguageDefinition">

    <Styles>
        <Style Key="IfWordStyle" ForeColor="Blue" BackColor="Default" Bold="False" Italic="False" Underline="False" />
    </Styles>
 
    <States> 
        <State Key="DefaultState">
            <ChildStates>
                <ChildState Key="IfState" />
                <ChildState Key="EndIfState" />
            </ChildStates>
        </State>
        <State Key="IfState">
            <Scopes>
                <Scope>
                    <ExplicitPatternGroup Type="StartScope" TokenKey="IfStartToken" Style="IfWordStyle" PatternValue="#IF" LookAhead="{NonWordMacro}" CaseSensitivity="AutoCorrect" />
                    <RegexPatternGroup Type="EndScope" TokenKey="IfStartToken2" Style="DefaultStyle" PatternValue="\n" CaseSensitivity="Insensitive" />
                </Scope>
            </Scopes>
        </State> 
        <State Key="EndIfState">
            <Scopes>
                <Scope>
                    <ExplicitPatternGroup Type="StartScope" TokenKey="IfEndToken" Style="IfWordStyle" PatternValue="#" LookAhead="ENDIF{NonWordMacro}" CaseSensitivity="AutoCorrect" />
                    <RegexPatternGroup Type="EndScope" TokenKey="IfEndToken2" Style="IfWordStyle" PatternValue="ENDIF" LookAhead="{NonWordMacro}" CaseSensitivity="AutoCorrect" />
                </Scope>
            </Scopes>
        </State> 
    </States> 
</SyntaxLanguage>

FYI, I define EndIfState in a way that will not consume \n char.

SyntaxEditor cannot load that file. As I was trying to narrow down to the cause, I found that it will load if I make 2 undesirable changes to EndIfSate:
1. Change LookAhead="ENDIF{NonWordMacro}" to LookAhead="ENDIF"
2. Change EndScope's CaseSensitivity="AutoCorrect" to CaseSensitivity="Insensitive"

the modifed EndIfState is:


        <State Key="EndIfState">
            <Scopes>
                <Scope>
                    <ExplicitPatternGroup Type="StartScope" TokenKey="IfEndToken" Style="IfWordStyle" PatternValue="#" LookAhead="ENDIF" CaseSensitivity="AutoCorrect" />
                    <RegexPatternGroup Type="EndScope" TokenKey="IfEndToken2" Style="IfWordStyle" PatternValue="ENDIF" LookAhead="{NonWordMacro}" CaseSensitivity="Insensitive" />
                </Scope>
            </Scopes>
        </State>

Would you shed some light on this? Thanks.

You have a couple problems here. You need to add a space before the {NonWordMacro} in the LookAhead so that the pattern parser knows you are referencing a macro.

Second, Regex patterns don't support AutoCorrect features. The Output window in VS tells you this when you try to load the language. Not sure if you noticed that:

AN EXCEPTION OCCURRED WHILE LOADING A LANGUAGE DEFINITION:
An error occurred while loading the DynamicSyntaxLanguage 'TEST':
A CaseSensitivity setting of 'AutoCorrect' is not permitted on regex lexical pattern groups.
The problem occurred near line 26, position 22

Thanks. Inserted a space before macro reference, and changed RegexPatternGroup to ExplicitPatternGroup. Works like a charm.
