Missing lexers from Lexilla?

PeterJones

I was able to confirm in source code that SAS and Stata lexers are part of the Lexilla bundle in Notepad++.

To happen automatically, they would have to be added to ScintillaEditView::defineDocType

Unfortunately, if Notepad++ doesn’t bring it out, I don’t know if there’s an easy way to activate it or not. Maybe one of the regulars who better understands the Lexilla and lexing requirements would be able to say whether there’s a way to “activate” one of the non-exposed lexers that’s already built into Lexilla.

the only way I know of is to use something like this.
I assume that unlike the errorlist lexer, SAS and Stata have keywords that need to be set when the lexer is initialized.
If you want to go this route and need help making it work, let us know.

I suppose I have forgotten what the script you linked to actually does. What is the errorlist?

I looked into the linked source and all I saw was “Makes the builtin errorlist lexer available for npp.” which doesn’t refresh my memory. :-(

The error list lexer hides ANSI escape sequences and colors the following text accordingly.

For example, something like this

with activated lexer looks like this

Ah, OK! If “ANSI escape” had been mentioned anywhere, that would have jogged my memory. Those two images would do well to tell the story if placed on the github page for the script.

@alan-kilborn - done :-)

Well, I am not the OP… but I started playing with it. I looked up what the 15 SAS styles were in LexerStyles.iface, and combined that with the sas.properties info from a recent SciTE 5.22 (which matches NPP v7.4.1) to come up with some colors for those styles. I changed the extension to .sas. With that, I’ve gotten it to the point where I can get the SAS highlighting on numbers and operators and %-keywords and comments.

The sas.properties lists the following sets of keywords:

# Keywords
keywords.$(file.patterns.sas)=%let %do

# Block Keywords
keywords2.$(file.patterns.sas)=also cards class data input model ods proc var where

# Function Keywords
keywords3.$(file.patterns.sas)=%printz

# Statement Keywords
keywords4.$(file.patterns.sas)=run

How do I add the list of keywords for each of those 4 keywords entries using your similar PythonScript?

(I picked SAS instead of Stata, even though I know nothing about either, because SciTE included sas.properties but not stata.properties)

I found it:

        editor.setKeyWords(0, "%let %do")
        editor.setKeyWords(1, "also cards class data input model ods proc var where")
        editor.setKeyWords(2, "%printz")
        editor.setKeyWords(3, "run")

For those who are curious, my script that seems to work for SAS is found at 23147-enable-sas-lexer.py in my scripts repo.

@peterjones

congrats, very nice. In the future it may be easier to create them with the newly added NPPM_CREATELEXER message.
