libo's Issues
Add a match() function
match(<pattern>, [<addresses>])
Should produce a bundle with
{
/full : {},
/partial : {},
/unmatched : {}
}
Empty bundle literal is missing in o.compose and o.expr
should be able to do
/foo : {}

osc_expr.h reports misplaced `}` in C++
osc_expr.h contains the following typo:
#ifdef __cplusplus
extern "C" {
#endif
and on the bottom:
#ifdef _cplusplus
}
#endif
What's hard to see is that _cplusplus contains two underscores on top, and one on the bottom.
bitwise opertators
would be nice to have the complete set of bitwise operators in odot expr lang.
one use case would be porting this type of thing to odot: http://countercomplex.blogspot.com/2011/10/algorithmic-symphonies-from-one-line-of.html

osc_expr_det() not implemented in osc_expr.c
It appears that osc_expr_det() has not been implemented and I believe this is the reason that the odot expression 'det()' does not return anything. I can see several headaches involved in implementing this, which might be why it was left for later.
check if arg1 free rules with goto cleanup in assignToBundleMember
free_arg1 should probably be initialized higher in the function --> https://github.com/CNMAT/libo/blob/master/osc_expr.c#L1853
but it's not clear to me yet, when arg1 should be freed as an atom_array
cleanup:
if(arg1 && free_arg1){
osc_atom_array_u_free(arg1);
}
o.expr needs a higher-order sort and sortidx
Since sort and sortidx are already varargs functions, we'll need two new versions of these.
o.expr memory leak
libo for Python 3 Swig not working with expression evaluation / function calls
Hi,
I've compiled libo from source and then created Swig and wrapped code for Python 3 and C integration.
Creating atoms, messages and bundles works well. Also the parsing of more complex bundles directly from strings.
While the parsing and serialization of bundles and expressions works the evaluation of expressions does not.
The given osc_expr_test.c file uses commands that don't exist anymore. E.g.:" osc_expr_funcall(f, &sbndl_len, &ser_bundle, &out)"
When trying to call directly into the newer: "osc_expr_eval(function, len, oscbndl, out, context)" from within Python 3 it results in Swig type errors. Especially concerning long * and the dereferencing of double pointer constructs.
Therefore, my question. Is there any newer refernce code (or any code at all) existing for usage examples of evalutaing odot expressions from within Python?
Thanks,
Tom
Add a nonzero() function to the expression language

safety check on free consistancy
digging around a bit, and noticed that some free functions do safety checks and others don't which sometimes makes following code conventions a little unpredictable.
void osc_array_free(t_osc_array *ar)
{
if(ar){
osc_mem_free(ar->ar);
osc_mem_free(ar);
}
}
void osc_atom_s_free(t_osc_atom_s *a)
{
osc_mem_free(a);
}
explode performance
explode seems really slow, not sure if this is new or not, but might be worth seeing if we can optimize this a bit in the new version?

"undefined symbol: fabs" error on linux
Hello! I built libo.so on linux, and it seems to build alright, but when odot tries to load it, it tells me "Could not register handle for external module: libo: undefined symbol: fabs.". fabs is a c++ command, so it seems to not find some library?
linux build notes
I just ran across an issue with building libo on linux that we should put in a readme at some point -- I'll start making notes -- using this issue thread as a place holder.
The folder location our Makefile looks for Flex's libfl.a is /usr/local/lib, however if you install flex as root it will go into /usr/lib or even /usr/lib/x86_64-linux-gnu which is where it put it when I installed in on a test debian jessie virtual box.

comma missing error
9/10 times the problem with an expression is a missing comma -- it would be really really really useful to have an error message that tells you where the missing comma should be.
timetag leap year
I think there might be a bug in the leap year lookup in osc_timetag.c -- I was just repurposing some of this code for OSC-timetag, and came across an issue with the year 2000 not being identified as a leap year. Not sure if it matters for o.timetag but it might so putting this note in for future inspection.
here's the fix I used in OSC-timetag-ops.c (mainly adding 1900 to t.tm_year in the test, and taking out the -1 offset from t.tm_mday)
uint32_t sec = 0;
for(int i = 0; i < t.tm_year; i++){
sec += SEC_PER_YEAR;
if(osc_timetag_isleap(i + 1900)){
sec += SEC_PER_DAY;
}
}
int leap = osc_timetag_isleap(t.tm_year + 1900);
int days_in_months[] = {0, 31, 59, 90, 120, 151, 181, 212, 243, 273, 304, 334, 365};
int offset = leap && (t.tm_mon > 1) ? 1 : 0;
sec += ((days_in_months[t.tm_mon] + offset + t.tm_mday ) * SEC_PER_DAY);
delete by address name string
could be nice to be able to delete an address by passing a string of that address, for instance when parsing SVG files, some attributes have dashes in their names, which odot doesn't like. So I'm reformatting any address that has a dash, but can't seem to delete the old name after reformatting in a lambda function using the address string.
README
This repo needs a readme.
Here are guidelines that should be followed:
https://gist.github.com/indexzero/1363524
memory handling naming scheme
Maybe it could be useful to somehow identify functions that allocate memory which needs to be freed later? Right now it's hard to tell looking at the API without looking at the specifics in the .c code or finding example code. (I just updated my o.table sorting object and had to look a bunch things up for the new version of libo)
Add constants to o.expr
phi(golden ratio)twelfth_root_twothirteenth_root_three
parsing large numbers append unnecessary '.' to represented number
...When reformatting in scientific notation.
Discovered this in Max, ala o.compose.

make fails on OSX 10.15; libfl.a not where libo expects
When attempting make on OSX 10.15 one gets the following error:
'error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: can't open file: /usr/local/lib/libfl.a (No such file or directory)'
I think this is because 'brew install flex' no longer writes libfl.a to this location, but rather to /usr/local/opt/flex/lib
I copied the file to the expected location and make completes.
check expr_parser.y file for leaks
there may be some leaks in the expr_parser rules, were $1 is not freed before returning (in particular when returning 1).
The == and != operators should work on bundles
This should just be done with memcmp, same as o.change.
