Re: Code block syntax highlighting
Even nested WITHs (although the heavy lifting is done by JSQLParser, where I am only a strong contributor for). A good test for the Highlighter is this one, Pygments gets it totally wrong: SELECT Overlaps( overlaps ) AS overlaps FROM overlaps.overlaps overlaps WHERE overlaps = 'overlaps' AND (CURRENT_TIME, INTERVAL '1' HOUR) OVERLAPS (CURRENT_TIME, INTERVAL -'1' HOUR) Cheers Andreas On Tue, 2022-09-20 at 08:10 +0200, Dave The Dane wrote: > Can it handle the WITH Clause? > ...probably the most unknown tool for structuring SQL Queries! > > DaveLaw, > Subquery-Factoring Evangelist 😎 > > On 20/09/2022 07:45, Andreas Reichel wrote: > > > > > Thanks Dave. > > > > I have written a good SQL > > Formatter https://manticore-projects.com/JSQLFormatter/index.html > > > > I only will need to add xsl-fo output which is easy. > > > > All the best > > Andreas > > > > On 20 Sept 2022 06:01, Dave The Dane wrote: > > > > > Would ANTLR & their Grammars for Java, SQL, etc. make sense for > > > this? > > > https://www.antlr.org/ > > > https://github.com/antlr/grammars-v4 > > > > > > All the best, > > > DaveLaw > > > > > > On 19/09/2022 10:07, Andreas Reichel wrote: > > > > > > > Klaus and Team, > > > > > > > > thank you for your feedback. > > > > I have actually figured out something working nicely: > > > > > > > > 1) based on Pygments > > > > 2) use the XSLFO Pygments formatter (can be installed from PIP, > > > > the code is fairly simple and straight forward) > > > > 3) from your XML document containing the Code Block: > > > > a) iterate through all code blocks > > > > b) call Pygments with the XSLFO Formatter and format > > > > the block into a temporary XML file (your FO styled codeblock) > > > > c) when this succeeded, add to the Code Block node a > > > > childnode with the absolute path to this temporary XML file > > > > 4) amend your XSL file and for each code-block use the > > > > XSL:COPY-OF directive to insert the FO formatted content of the > > > > temporary XML file into the final PDF directly.

Although there is one more requirement: printing formatted code blocks with syntax highlighting (e. g. SQL or Java code snippets). What would be the best way to achieve that? I have tried to convert the SQL/Java code to SVG via Pygments and to insert it as EXTERNAL_GRAPHICS. This works in general, but I cant control the sizing. Each EXTERNAL_GRAPHICS will have a different size of characters based on the size of the graphics. Does anyone know a better way or has done something similar already? I would appreciate any idea or hint. Thank you in advance and best regards Andreas Hi Andreas, I haven't had such a problem yet, so I don't know tools that perform the actual syntax highlighting. But what I do not understand is why you are using SVG and external graphics. FO is capable of doing preformatted text and also of colorizing text. So no need to go that path. Since you using scripts anyway (as far as I understand), it shouldn't be too complicated to generated XML fragments to be inserted into you document.
