Highlighting Issue

Submitted by Lance on Friday, 9 March, 2007 - 20:29

I am having trouble getting my syntax highlighting to work with one form of comments. I am making a highlighter for Pick BASIC. Comments can be in the following format:

REM This is a comment
* This is a comment
A = A + 1 ;* Everything after the * is a comment
100 * Everything after the * is a comment. The 100 is a label.
MYLABEL: * Everything after the * is a comment. The MYLABEL: part is a label.

Currently everything is highlighting fine except the last two comment types. It doesn't seem to recognize them as comments. Here's the relevant part of the highlighter xml:

<MODE>
	<PROPS>
<!--		<PROPERTY NAME="lineComment" VALUE="*" /> -->
	</PROPS>

	<RULES IGNORE_CASE="TRUE" HIGHLIGHT_DIGITS="TRUE">
		<SPAN TYPE="LITERAL1" NO_LINE_BREAK="TRUE">
			<BEGIN>"</BEGIN>
			<END>"</END>
		</SPAN>
		<SPAN TYPE="LITERAL2" NO_LINE_BREAK="TRUE">
			<BEGIN>'</BEGIN>
			<END>'</END>
		</SPAN>


		<!-- conditional compilation -->
		<EOL_SPAN_REGEXP TYPE="COMMENT1" AT_LINE_START="TRUE">\d+ \*</EOL_SPAN_REGEXP>
		<EOL_SPAN TYPE="KEYWORD2">#if</EOL_SPAN>
		<EOL_SPAN TYPE="KEYWORD2">#else</EOL_SPAN>
		<EOL_SPAN TYPE="KEYWORD2">#end</EOL_SPAN>

		<EOL_SPAN TYPE="COMMENT1" AT_WHITESPACE_END="TRUE">*</EOL_SPAN>
		<EOL_SPAN TYPE="COMMENT1">;*</EOL_SPAN>
		<EOL_SPAN TYPE="COMMENT1">; *</EOL_SPAN>
		<EOL_SPAN TYPE="COMMENT1">REM</EOL_SPAN>

Functions and operators are listed below here but didn't seem relevant to the problem. Any help on getting this working would be appreciated. Thank you in advance!

Any help?

No comments?

Oops?

I thought I had put this in the Using jEdit section... My apologies for having it appear here... Requesting an admin move this. Thank you!

Hi Lance,

I just wanted to answer you, but when I paste my lines into the edit field of this forum and press the "Preview Comment"-button, my lines are completely changed... . Didn't find out, how to switch this behaviour off. You could either tell me, how _you_ succeeded in posting _your_ code and have it displayed correct, or you can give me your email address (maybe in some spam save "encryption").

In your span_regexp is missing the HASH_CHAR Attribute.
I tried out a solution on my jEdit4.2, and it worked.
I have almost no knowledge of BASIC, so maybe my solution has to be adjusted slightly.
And, the RegExp-parser of jEdit4.3 is slightly different to jEdit 4.2, so there is a minor risk, that my lines are not working for jEdit4.3.

HASH_CHAR

by Lance on Thu, 22/03/2007 - 22:16

The problem with HASH_CHAR is that the line could begin with ANY number, or any ALPHANUMERIC followed by a colon. This is why I omitted HASH_CHAR. According to what I've read in the release notes, HASH_CHAR is optional, and if omitted, jEdit will check every line for a potential match as if the hash character had been found.

I was able to get this working by putting in the EOL_SPAN_REGEXP line 9 times, specifying a different numeric (0-9) as HASH_CHAR. I shouldn't have to do that though. Perhaps this is a bug?

hash_char

by Axel on Fri, 23/03/2007 - 06:36

You are right. I just compared, what help file of jEdit4.2 and 4.3 say:

- For jEdit4.2, hash_char is a must
- For jEdit4.3, hash_char is optional Smiling

My solution was using 9 + 26 different hash_char ... , and I tried it on 4.2.

Does hash_chars (with the trailing "s") work for you?

- Axel

Just curious: How did you get your code into this forum and getting it displayed correct?

Pasting Code

by Lance on Fri, 23/03/2007 - 21:41

I pasted the code in to the comment box, then I replaced all > and < chars with > and < . I then enclosed the whole thing between <PRE> and </PRE> HTML tags... If you know your html, this will make sense. Let me know if you need more info on how to do this. =)

Mode File for BASIC

Oh, nice, this works! So I show you the code for jEdit4.2. Think, this will work on 4.3, too. But on 4.3, it should be easyer with the hash_char being optional and having the "hash_charS". - Axel
