I guess I have found a small glitch in echo with HTML commands when the commands are not properly closed. For instance, text = "Test"; echo(str( "<h4><p style='background-color:lightblue;'>", text )); instead of: text = "Test"; echo(str( "<h4><p style='background-color:lightblue;'>", text,"</p></h4>")); will paint the console background with blue. The new background color will extend beyond the echo text and will be kept even in the following code previews. To reestablish the white background, some echo like bellow might be needed: echo("<p style='background-color:white;'></p>"); I think that echo should force a close of all open HTML commands before ending. _______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org |

It already is disabled for most cases that output to console but it seems there's still some places not fixed. ciao, Torsten. _______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org

The current HTML support was an accidental feature leaking the internals of the GUI control used as console window. That's also the reason why it changed behavior some time ago causing all sorts of issues and different behavior depending on the OpenSCAD version. The only way for providing a stable way of generating output (with string formatting, no ECHO prefix, ...) would be having a dedicated output window. Collecting ideas for that would help a lot. ciao, Torsten. _______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org

A sexta, 20/12/2019, 23:16, Torsten Paul What are the formatting features used? Nothing more then colouring text and it's background and add some line breaks. But, for instance, I was unable to add an extra line break at the end of my formatted text. I must admit I am less than a beginner in HTML. My intention is to visually distinguish error, warning and info messages issued by a library. _______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org |
We could theoretically add support back in for html-specific output as a separate module without much effort I think, Call it something like "html()", "html_echo()", or "echo_html()". The current formatting code is in mainwin.cc:consoleOutput function ( https://github.com/openscad/openscad/blob/2a943a57f9d23511c0021b228dee6b6eb9ae440d/src/mainwin.cc#L2923-L2946 ) , and it works by checking if the message starts with "WARNING:", or "ERROR:" etc to highlight those messages in different colors. In the most recent builds, since Dec. 11, the echo appends plain text only to the console, and those specific formatting options can't be invoked directly by the user(they couldn't before either) because echo() statements always start with "ECHO:" So another option which could be useful is if scripts were able to apply some of those builtin formats to highlight their own warnings (and maybe errors?) without requiring html either. So for example echo() could take an optional "message_type" parameter that would alter its prefix from "ECHO:" to some other from a list of pre-defined options. If we did something like that we might also want to differentiate between messages coming from the application, vs those coming from a script. Maybe prefix "SCRIPT-WARNING:" instead of "WARNING:" etc. One last note which doesn't directly help but might be some consolation for library writing: (version_num()-20191211 >= 0) Should return true if the build has had echo html support removed, based on the merge date. -Hans On Fri, Dec 20, 2019 at 6:13 PM Ronaldo Persiano <[hidden email]> wrote:

I have lots of code (A LOT!!!) using the HTML style to structure/color text
for complicate code. If the HTML feature is disabled, all those hard work will be wasted. I haven't have a chance to try newer release to check how devastating it is.

On that note about adding the ability to issue "WARNING" and "ERROR" messages
that are highlited, how about also a "NOTICE" message that is also highlited but for things that aren't necessarily a problem. Alternatively, I'd probably prefer "color=" and "bgcolor=" parameters added to echo, so we can just specify colors for our messages and lead off with whatever capitalized text we want to (after the "ECHO:" bit, of course) if we want any at all. Just use the same color options as already available for the "color" command. Too bad this: *color("red") echo("This should be red text.");* doesn't work. :) thehans wrote > The current formatting code is in mainwin.cc:consoleOutput function ( > https://github.com/openscad/openscad/blob/2a943a57f9d23511c0021b228dee6b6eb9ae440d/src/mainwin.cc#L2923-L2946 > ) , and it works by checking if the message starts with "WARNING:", or > "ERROR:" etc to highlight those messages in different colors.

Probably depends on the terminal you're on, at least for the color option.
There is some way for a program to determine if the terminal it's interacting with supports color or not, isn't there? Scaling might have to be just ignored altogether for command-line. nophead wrote > What would these do when run from the command line? > > On Mon, 6 Jan 2020 at 18:27, Jordan Brown < > openscad@.maileater > > > wrote: > >> On 1/5/2020 11:02 PM, egburr wrote: >> >> Too bad this: >> *color("red") echo("This should be red text.");* >> doesn't work. :) >> >> >> Or >> >> scale(1.1) echo("Big text"); >> -- Sent from: http://forum.openscad.org/ _______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org |

What happens on command-line with current "ERROR" and "WARNING" messages that
are currently colored/highlited in the OpenSCAD console? I'm guessing they come out as just plain uncolored text? nophead wrote > What would these do when run from the command line? > > On Mon, 6 Jan 2020 at 18:27, Jordan Brown < > openscad@.maileater > > > wrote: > >> On 1/5/2020 11:02 PM, egburr wrote: >> >> Too bad this: >> *color("red") echo("This should be red text.");* >> doesn't work. :) >> >> >> Or >> >> scale(1.1) echo("Big text"); >> -- Sent from: http://forum.openscad.org/ _______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org |
Yes they need to be plain text for my usage.

I guess it was unclear that I was 97% kidding. Semi-seriously... You *could* use ANSI x3.64 escape sequences for color. Addenda bring in 24-bit color support. However, I don't see any size support. That would mess up any postprocessor, but you'd use the same strategy that was used for (e.g.) ls and its color-coding of file types: have OpenSCAD automatically disable colors if stdout isn't a terminal. Tempting and cute as this scheme might be, I don't think you'd actually want to have the same operators affecting your console output and your geometry. Just because a particular component is scaled or colored doesn't mean that you want its diagnostic output to be scaled or colored. _______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org |

I also use some simple HTML formatting in my output window.
I have a rudimentary library that creates documentation for my other libraries, so that I can quickly remind myself of function/module syntax without loading up the library source directly. I don't use colours as much but I do use text formatting - for example: <http://forum.openscad.org/file/t311/Screenshot_2020-01-11_at_16.png> Will this be lost? -- Sent from: http://forum.openscad.org/ _______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org |

This is not a direct answer to your question, but some of my programs has a
switch to output either HTML-encoded text or plain text. nophead wrote > What would these do when run from the command line? ----- $ Runsun Pan, PhD $ libs: scadx , doctest , faces ( git ), offline doc ( git ), runscad.py ( 2 , git ), editor of choice: CudaText ( OpenSCAD lexer ); $ Tips ; $ Snippets -- Sent from: http://forum.openscad.org/ _______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org

So perhaps we need a variable to indicate command line mode.

My use case for "HTML" output is to generate and output SVG (mainly in
generating nets from solids). I used to output this with angle brackets but thanks to the change to interpret such characters as HTML which since they are not and are all ignored, I've had to change to outputing < etc. Of course, I would prefer to be able to output the SVG directly to a file rather than the console :) -- Sent from: http://forum.openscad.org/ _______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org |
