[Geany-devel] compiling a C/C++ header (Re: C/C++ Header filetypes)

I'm now a little confused, I think we have a terminology problem so let me
spell out what I mean below. We can continue to try to sort out the best
solution by discussion because I have a sudden family problem and will be
away from home and work and unable to code anything for a couple of weeks.
I will be able to continue discussion thanks to gmail being accessible
anywhere. Perhaps we should slow the discussion down to every couple of
days so as to not use too much of your time.
I am confused about what we each mean when we are talking about 'build'
here, and looking back I am not sure I have been consistent in my usage
either. So I suggest the terminology for this discussion:
1. Filetype commands, menu items labelled:
- build which I suggest we call build(link) to distinguish it from other
meanings of build and
These commands depend on the filetype and and in the new build system will
have user configurable menu label and commands stored in the user
preferences directory (as is currently done for the commands only).
2. Preference commands, that is the menu items currently labelled 'make
something', which I suggest we call make commands to distinguish them from
the filetype build command. These commands will have configurable menu
label and command stored in the user preference directory. These commands
can also contain an override for the execute command.
3. Project commands which override preference commands (make commands) when
a project is open. If changed whilst a project is open they will be stored
in the project file. These commands can also contain an override for the
For most of this discussion on headers I have been talking about filetype
commands because both preference and project make commands are independant
of the type of file that is open. Having language specific commands in
command sets that are present for all languages is not a nice solution. And
if it is in project files then the user has to configure it again and again
for each project.
Although having header compile as an extra filetype command can work, the
build(link) menu item can do funny things if invoked on header files. This
is probably fine for an expert like Nick but could be an issue for a
beginner just trying things out, thats why I don't like having commands that
are not useful available to users.
In the time that I'm away lets see if we can find a solution that doesn't
have the problems I've listed above or in previous emails but is simple to
implement. Thanks for your patience we will get there.

I agree that the ultimate would be to have unlimited commands, but that
makes for a more complex configuration GUI and
configuration/preference/project file format. My proposal for now is to add
one extra filetype command (compile, build(link), execute and spare) and one
extra make command (make all, make custom, make object, execute and spare),
remembering all labels and commands can be configured..

As I said above I am confused about where you are suggesting this command to
be added, as a filetype command or as a make command?

I'm also confused by this, headers (in my experience) don't need any more
include paths than the source file needs ( I guess you are talking about
things like Gtk+ and the like that use pkg-config, most other stuff is in
the search paths by default for my C++). So the compile command for headers
would have the same includes and agruments as the command for sources.
Compiling headers as a project make command would be great, but I don't know
how to set up make and other builders to compile headers (remember that the
original reason for my build commands changes was to support different
builders) If there is no output file, what prevents make compiling all the
headers every time? Gcc leaves a .gch file but not all compilers do that
(eg Intel C++ for Linux).
Anyway all I really want is to be able to compile my new or newly modified
C++ header file for syntax check purposes. Once it doesn't inject several
hundred syntax errors into the source files that include it I can get on
with making them compile and making it actually work using the make
commands. (Yes, the most recent new C++ header file I built had several
hundred lines of error messages on first compile (not bad for a file only
370 lines long), This is common because some C++ syntax is really picky and
unintuitive (meaning templates) and takes a few tries to get right and C++
headers typically have more in them than C headers.

As I said above, for experts it is reasonable but as the filetype commands
are probably more used by beginners who havn't got up to speed with make
yet, I see having it available as a problem.
