[fpc-devel] TMemIniFile proposed patch
Hi, I notice my application take a lot of time while writing it's configuration to a .ini file using TMemIniFile, up to 10 seconds for a 12K file. With the proposed patch it do the same instantly. This is because TMemIniFile do not implement it's own WriteString function but use TIniFile one. This imply to write the full file each time a string is changed. Delphi TMemIniFile use a buffered write as describe in this paragraph extracted from the Delphi help: Unlike the TIniFile object, which also encapsulates INI file data, TMemIniFile buffers all changes to the INI file. The INI file is read once, when the object is first created. ... After the data is read, any changes to the data are stored in memory. To write the data from memory back to the associated INI file, call the UpdateFile method. There is no problem while reading the file because TIniFile.ReadString is already buffered contrary to the Delphi implementation. I hope this change to fcl/inc/inifiles.pp (or a variation) can be applied to the fcl.

{$APPTYPE console}
I think that is with Delphi.
Isn't freepascal the opposite, where in fact command line mode is
default
and you must explicitly specify app type of GUI if you want a GUI?
Oh, I thought the original question was about Delphi - one of the recent
questions were :)
Oh it might have been - I guess it depends on his decision to use fpc or
delphi? :)
Which should I use when creating a server-side web language?
I'd recommend FreePascal, no doubt about it. It would be perfect for the job.
(Not that delphi would be bad, but I'd say it's biggest strength is GUI
design)

Do you know of a better Pascal IDE? The FreePascal IDE is a DOS window and
it's really hard to work with.

Lazarus? BTW: Most fpc development is done with the text mode ide and
it's very efficient to work with it especially since it works also
through ssh etc.

I didn't know I could use Lazarus for code that is only Pascal, but I guess that's just stupid to have not thought of that. About the text mode ide; I have a lot of trouble with copying/pasting and moving through the text.
