I didn't check in detail what the changes are but since no GRegex code is
involved and since everything seems to work after the patch, I think it's OK.
In addition, add automatic memory MIO opening to read.c for small files
and remove the same optimization from Geany. Simplify tm_ctags_parse()
as the memory/file branches are identical now.
In uctags File is made private and mio gets inaccessible. At the moment
it's used by c.c and lcpp.c to get the parameter list. The C parser
"marks" the position where the argument list starts and once the right
")" is reached, string corresponding to this range is read from MIO,
filtered and used for parameter list.
For macro parameters the end of parameter list is handled in a slightly
obfuscated way - since the code from read.c reads the code by lines,
getInputFilePosition() returns the position of EOL so the parameter list
is read between '(' and EOL.
The code had to be modified to collect the potential parameter string
on the way - vString *signature has been added to lcpp.c and every
getcFromInputFile() and ungetcToInputFile() has been converted to
getcAndCollect() and ungetcAndCollect(), respectively, which in addition
perform the parameter collection when needed. Unfortunately this involves
many places in lcpp.c and we must be careful to always use these instead
of the standard ones from read.c.
We cannot rely on the implicit reading of whole lines and must add such
a code ourselves: just plain reading and collecting is enough. In addition
I added handling of multi-line signatures which was missing before.
In tests "bug1585745.cpp" and "cpp_destructor.cpp" the new code fixes
missing () in destructors when there's a space between tilde and name.
In "simple.d" test it fixes wrong function prototype.
The output of test "bug507864.c" seems to be worse than before but it was
already broken before and apparently the compiler is confused by it.
Add access functions and use them outside entry.c. In addition to functions
defined in uctags setMaxTagsLine() had to be added because it is needed
in parser.c (at the moment, will be probably gone in some of the next
commits).
Sync things which are possible to sync from lcpp.c/h. This file is heavily
dependent on c.c and since our c.c differs quite significantly, it's
not possible to use the universal-ctags implementation right now.
This commit started innocently as an attempt to grab options.c/h from
uctags. However it started referencing other files (which started
referencing other files) so the result is lots of new files are added.
When trying to make it compile, I run into many differences of existing
code which would have to be resolved. As all the added code is more or
less garbage for Geany, I just simply commented-out various function
bodies so it compiles without additional modifications. Should get fixed
once more files get synced with uctags.
Added e_msoft.h, changed configure.ac to make more checks for header files
so we have corresponding macros defined, drop HAVE_REGEX macro check which
isn't defined any more, drop debugging function from lua parser (complains
about missing definition of errout).
Tested only on Linux (TODO: Windows, OS X)
Also move eStrdup() to the correct position in the header.
In addition add the same includes into debug.h as those in uctags (the
removal of vstring inclusion inside routines.h causes compilation errors -
it would be best to explicitly include all needed files in every source to
avoid problems like this but let's do just syncing the two implementations
for now).
