[Lazarus] Is it an error to have mutiple help viewers enabled?
One of my copies of Lazarus shows that ChmHelpPkg 0.2 is installed. If I hit F1 in a field in ObjectInspector I see what looks like a chm viewer for a fraction of a second then I get an Access Violation and it goes away. Meanwhile if I look at Firefox it's trying to open a chm file. There are plugins for that, I'm downloading one, hopefully. Figured how to change web browsers, just type in the path to one beside where it says BrowserPath. fpdoc looks good, but why is fpcdoc.chm in the Lazarus 1.0.14 tarball yet gone by 1.6.0? It seems to be the generator of most of your documentation, whether in chm, inf or html. It would probably not be hard to add epub as a format since that's zipped html. I'm trying to manually construct the whole tree from toc.chm down as one file. Just what everybody should carry in their phone as an epub. :) PDF or dejavu wouldn't be bad as long as you can generate the internal hyperlinks under program control. FPC and Lazarus look like a giant project that's gone on for many years. I remember trying FPC in about 1998 and sticking with Borland. Now that they're mostly gone and Lazarus has gone multiplatform it surpasses anything Borland did. -- Credit is the root of all evil. - AB1JX -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] Pretty neat stuff Lazarus
I ignored the help issues for now and opened my trusty Delphi 3 on my laptop for reference. Cranked out my first program in a couple hours. It was 20 megs until I turned optimization on and debugging off, then it went down to a little over 4. The C command line version is about 8 K, but oh well. Installing and running as root seems to present a strange problem in that when I rebuild the IDE it doesn't write the new version to /root/.lazarus/lazarus, it stays in /usr/local/bin. I'll figure it out. So that's why adding packages and rebuilding seemed to not work, because I had lazarus-ide in my rxvt menu but the new versions were ending up as /usr/local/bin/lazarus and I wasn't using them. Rebuilding the real thing while I was running it crashed big time. New questions: Can I use my Deplhi 3 help files? These are old-style .hlp files, not .chm. How can I change my help browser from Opera? Firefox thinks it's default but Opera keeps getting called somehow. The problem with it is that since it's not open source I'm actually running a Linux binary under Linux emulation, which is slow. I saw the illegal character error only once, doing a clean and build got around it. Now to try compiling this into an apk file... -- Credit is the root of all evil. - AB1JX -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] Trying to work around "Illegal character in format string"
OK, I downloaded 1.6 overnight and installed it, haven't seen the illegal character error since. Nice to add: If the OS is one of the BSDs, Tools -> Options -> Environment -> 'Make' executable should default to gmake on install. Or just look for gmake in the path and default to it if found. OpenBSD's make gives an error on -w as an argument which rebuilding the IDE by the buttons at least uses. There's no 'make uninstall' so I renamed my old lazarus directory and installed beside it. Should I have maybe removed ~/.lazarus? I still can't get the chmhelp package to install, even after upgrading, rebuilding the IDE, restarting. It's mentioned in ~/.lazarus/idemake.cfg and ~/.lazarus/staticpackages.inc but it still shows with a green +. Should I be able to get to the point where I can do ctrl-F1 on a keyword in the editor to bring up help on it? F1 in a field in Object Inspector is working to bring up htmlhelp. Whaddya mean read the documentation? It doesn't even have a manpage. :) -- Credit is the root of all evil. - AB1JX -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] Trying to work around "Illegal character in format string"
I guess I've got to get to the bottom of why I get this “Illegal character in format string” error under OpenBSD. I seem to be able to work around it in programs I might write by taking the Run → Clean up Build Files -> Clean up and Build approach. But I don't seem to be able to rebuild the IDE to add help packages Trying to install chm help using the directions at http://wiki.freepascal.org/Installing_Help_in_the_IDE My Lazarus installed itself into /usr/local/share/lazarus I built lhelp.ini by loading it into the ide and doing a clean and build. Now I have an /usr/local/share/lazarus/components/chmhelp/lhelp/lhelp executable. Look for chmhelppkg: doing "save and rebuild IDE" to install it, got "illegal character in format string". Did my usual fix, restarted the ide, but it still shows as not installed. I need to rebuild the IDE I think, but the "save and rebuild" option is grayed out now. Clicked the Help button for hahas. http://wiki.lazarus.freepascal.org/IDE_Window:_Installed_Packages opens in Opera (why Opera not Firefox, Firefox is the default? Internal setting I guess) Tools -> Build Lazarus from http://wiki.freepascal.org/Install_Packages "Illegal character in format string" again. "clean and build", rebuilt lhelp apparently. Build with normal IDE gets me the same error, I'm in a loop. A similar thing happens when I try to install ExternHelp 1.3 Looking at configuring the build. lazarus-ide is in /usr/local/bin so I browsed to that as the target directory. gtk2, i386, openbsd. Verbose, restart after build. Click build, watch. After "Compiling IDEIntf 1.0" the Illegal character error is back. Click OK, IDE is still open so I close and reopen. Package -> Install Packages. chmhelp still has a green + and isn't installed. Trying inf help. Going to http://sourceforge.net/projects/fpgui/files/fpGUI/Documentation/ I ended up with 1 renamed zip which has in it fcl.inf, fpc_lang_ref.inf, fpgui.inf, rtl.inf all dated Apr 4 2015 Created /usr/local/share/lazarus/components/infhelp1 and copied the infs in there. How to connect to them? Back to rebuilding the ide. Built lazbuild, trying lazbuild -B lazarus.lpi: 106110 lines compiled, 12.6 sec 8 warning(s) issued 64 hint(s) issued "Compiling package SynEdit 1.0" completed Start IDE, look under Packages, the help packages still aren't installed. I don't know where this illegal character error is coming from, but I didn't get it when I built and installed initially. -- Credit is the root of all evil. - AB1JX -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] Lazarus Digest, Vol 99, Issue 32
Re: [Lazarus] Suggestion for TRadioGroup documentation OK, I was just hoping for a sentence or paragraph to be added to the documentation. In HTML you group radiobuttons by giving every button in the group the same name but different values. I started with a tgroupbox then went to a tradiogroupbox when it didn't work. Still got -1 for ItemIndex so I defined some with tstrings and got a duplicate set, but itemindex works on those. Aha! But a radio button that doesn't belong to a group isn't much different than a checkbox. I agree with most things said about documentation except that nobody has time to read it all. And it can change, so you have to keep rereading. Being a multilingual project complicates things too. When I started in Linux I read (and printed) howtos, took them very seriously. But by the time I got around to doing what I was reading about I found the howtos were years old and almost worthless. I don't have my internal help working yet, and it may not be as good as Delphi's when I do. So I Google a lot. Documentation that looks like it came out of doxygen turns me off because so much of it's bad. Good internal help may be a thing of the past. I've seen bad documentation that looks like it was written by fledgling technical writers and tells you obvious things. I agree, the programmer is the ultimate reference/authority but I've had to document projects and didn't enjoy it either. So I think some compromise like the newbie tech writer writes it and the programmer checks/edits it might work. How that works in a multilingual environment I haven't a clue. Really, I'm sort of trying out Lazarus again. A year or so when I tried it last I kept getting an error which, from Googling, I thought came from the fact that OpenBSD basically has no working locale and little interest in it. So I gave up on using it. Now I find it's better, and when I get the error doing a "clean up and build" seems to always get rid of it. "Illegal character in format string" I think it was.

[Lazarus] Suggestion for TRadioGroup documentation
I don't think the existing documentation stresses the point enough that if you use individual TRadioButtons you won't be able to use ItemIndex to find out which one is checked. Creating a TRadioGroup as a container then adding TRadioButtons to it does nothing useful, ItemIndex is always -1. Change Parent doesn't seem to fix it. It seems like that worked in Delphi, I rarely used string lists. To use ItemIndex you have to populate the TRadioGroup using strings. I haven't found out yet whether the strings can be changed under program control, but I was building a context-sensitive menu, planning on changing the captions on the buttons to suit the context New to the list, I've got a resume at http://devio.us/~ab1jx/files/resume.pdf I used mostly Delphi 3 from when it first fascinated me about 1998 through the end of my last job in 2009. Turbo Pascal before that, VAX and Apple II Pascal before that. Used to tinker with Oberon Native. I spend most of my time in OpenBSD lately so I've been writing C for the last 6-7 years. Delphi was the thing I missed most about Windows.
