[Lazarus] Offer: Fixing CodeTools
I'd like to do some fixin' on CodeTools. Who is most familiar with it? I've worked with it a little in the past, and submitted at least one patch to it before, but I recall it was kinda unbearable. I keep finding things that don't work with it including, record helper insight, inner types not being seen, and other things. If whomever is really familiar with it would be kind enough to meet me on a freenode irc channel and answer a few questions while we look at the source code, I might be able to spend some productive time fixing the previously mentioned issues and whatever else needs fixin'.

I was just evaluating the latest debugging features in Lazarus IDE, and
comparing GDB and fpDebug output.
I also wanted to see if Lazarus IDE had something like Haiku's Debugger
has - Array Ranges. If it didn't (Repeat Count seems close), I thought I
might take a shot at implementing it. It doesn't seem too hard to
accomplish [please correct me if I am wrong].

I opened one of my regular projects and built and ran it. It ran perfectly. I could see no problems whatsoever.

I added a couple of controls as test: a bit btn, with an onclick, and some hint text and a TArrow with a double click. I also renamed one of my existing TButtons. I also moved around the form a bit, testing as you suggested. I then did a build. It reported success. But F9 to run and I got the debbugger error immediately, as shown. Even though the warning was drastic, Laz IDE was responsive after I pressed OK. Did another build. Message window was now blank of hints and warnings but still showed compile success. Another run and the same debugger error. I reversed all the changes I had made, in steps. Still got debugger error. But after each change the message window was again filled with hints. After a shutdown and restart of Laz, still got debugger error. Without shutting down, I reloaded the original project. Still getting debugger error. I then shutdown Laz, re-opened it.

Vince, this is just a personal opinion but you may find this forum a little 'choppy' to pick up general and structural knowledge from. I would recommend the Lazarus Manual for a reasonable structure and it seems to be quite complete. I have been heavily into Kylix for the past number of years and the IDE for Lazarus seems to be more reliable and the compatibility to Kylix is also excellent, from my experience. Using that logic, any book on Kylix would probably put the 'structure' would also help in using Lazarus. My only additional comment would pick the database you plan on using and stick to it, mysql seems to be the most used, but I don't want to start a fight with any of the others, I took my poll made my decision and like the decision so far, but that is just me. Try to jump into development with a short, real problem that will teach you the most for the least code, have a few glasses of wine, with dinner. Then the next day, decide what you learned. I haven't doubted for a day I made the correct choice, first with Delphi, then Kylix and now Lazarus, good luck. John A. Ward, j...@mbstemps.com Hi John Thank your for your message. Do not worry, I will not bother the list for general knowledge questions concerning Pascal or Lazarus, I have already found some documentation that I will use before starting the development of the program. Have a nice day :) -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Honestly, i wouldn't put down Sqlite :-). I would. Any database that allows you to store a string in a field that is declared as integer (as sqlite does), is out. It goes against the basic rules of the RDBMs: ACID. Period. If you ever encounter such a situation, the whole pascal db code simply goes 'poof'. If the table definition says 'integer', it should be an integer. if sqlite does not guarantee this (and it does not, it considers this a feature), it is out. I don't even understand that any pascal programmer (pascal being stronly typed) can consider such a system. But there are many things I don't understand :) Is there any other free WinCE database engine?

You use sqlite just like any other libraries, no setup required, just supply a single dll/so (or nothing if you statically linked it). With firebird embedded, you need to: - supply a bunch of dll/so (firebird doesn't consist of just one) - specify a config file - set some environment variables before program start easy, but certainly more than sqlite. I've never done those last two steps with Firebird Embedded (specify a config file and set an environment variable).

But there are many things I don't understand :) As sqlite page says, it's designed to compete with fopen. sqlite does a good job for easy data storage and retrieval, where it doesn't need complicated setup like fopen, but it can be used (in terms of storing and retrieving data, from its users point of view) like an rdbms :) -- View this message in context: http://free-pascal-lazarus.989080.n3.nabble.com/Lazarus-Embedded-small-database-tp4040516p4040592.html Sent from the Free Pascal - Lazarus mailing list archive at Nabble.com. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
