Class FortranParser
java.lang.Object
com.ibm.lpex.core.LpexCommonParser
com.ibm.lpex.fortran.FortranParser
- All Implemented Interfaces:
- LpexConstants, LpexParser
- public class FortranParser
- extends LpexCommonParser
Base document parser for Fortran.
By default, it uses the free-source-form Fortran lexer.
Actions and assigned keys added by this document parser:
- comment (Ctrl+/) - to comment the visible selected elements
- errors - for a selective view of the errors in the document
- functions (Ctrl+G) - for a selective view of the functions and
subroutines in the document
- outline - for an outline view of the document
- uncomment (Ctrl+\) - to uncomment the visible selected elements.
Keys already defined (e.g., by the active base profile) to an action
different from nullAction are not redefined in here.
Action modified by this document parser:
- contextHome - to skip comment-defining characters when determining
the start of the text.

FortranParser
public FortranParser(LpexView lpexView)
- Constructor for the parser.
Adds all of the parser specifics to the LPEX document view.
Initializes the Lpex view for the parser: it sets up all the style
attributes, classes, etc. for the language-sensitive edit features
supported.
- Parameters:
- lpexView - the LPEX document view associated with this parser
getFortranLexer
protected IFortranLexer getFortranLexer(LpexCharStream charStream,
FortranLexerStyles lexerStyles,
FortranLexerClasses lexerClasses)
- Retrieve the Fortran lexer to be used by this parser.
The default implementation of this method returns a new FortranFFLexer
(the free-source-form Fortran lexer). To use a different lexer, override
this method.
parseAll
public void parseAll()
- Total parse of the entire document.
Done initially, after a document has been loaded in LPEX, or after an
updateProfile command.
- Specified by:
- parseAll in class LpexCommonParser
- See Also:
- Total and incremental parse
parseElement
public void parseElement(int element)
- Incremental parse.
- Specified by:
- parseElement in class LpexCommonParser
- Parameters:
- element - the (first) element whose committed change triggered the
parse, or the element that precedes/follows a deleted block.
The parser may identify other neighbouring elements that
will have to be reparsed as a unit
- See Also:
- LpexView.parsePending(int),
LpexView.elementParsed(int),
Total and incremental parse
getProfile
public ResourceBundle getProfile()
- Returns the parser's properties profile resource bundle.
- Overrides:
- getProfile in class LpexCommonParser
- See Also:
- LpexCommonParser.getProperty(java.lang.String),
Parser properties
getLanguage
public String getLanguage()
- Returns "Fortran", the language supported by this parser.
- Overrides:
- getLanguage in class LpexCommonParser
- See Also:
- LpexCommonParser.LANGUAGE_FORTRAN
getPopupItems
protected String getPopupItems(int popupLocation)
- Retrieve parser's contribution to the popup.
This parser contributes to the "Filter view" submenu (Functions,
Logic outline, Errors) and to the "Source" submenu (Comment, Uncomment).
- Overrides:
- getPopupItems in class LpexCommonParser
- Parameters:
- popupLocation - the location on the popup menu of the items
requested, one of:
LpexCommonParser.POPUP_TOP, LpexCommonParser.POPUP_FILTERVIEW,
LpexCommonParser.POPUP_SOURCE, LpexCommonParser.POPUP_END
- Returns:
- this parser's contribution to the popup menu, or
null if none
setStyleAttributes
public void setStyleAttributes()
- Define parser's style attributes.
The following style characters are set:
'_' (layout blanks),
'p' (punctuation/operator),
'c' (comment),
'r' (remark),
'a' (name),
'e' (error),
'k' (executable statement keyword),
'o' (nonexecutable statement keyword),
's' (special program keyword),
'v' (special program-end keyword),
'n' (numeric),
'q' (character literal),
'd' (compiler directive),
'f' (continuation indicator),
'l' (label),
'i' (ignored).
getCommentStyleCharacters
public String getCommentStyleCharacters()
- Return the style characters used for styling comments and remarks ("cr").
This is used by compare sessions when the compare.ignoreComments
option is in effect.
- Overrides:
- getCommentStyleCharacters in class LpexCommonParser
isTokenDelimiter
public boolean isTokenDelimiter(char ch)
- Returns true if the specified character is a token delimiter.
- Overrides:
- isTokenDelimiter in class LpexCommonParser
- See Also:
- LpexCommonParser.getToken(com.ibm.lpex.core.LpexDocumentLocation)
