Hi Steve,

I am currently working as a member of the Documentation Team, updating
Chapter 18 of the Calc Guide (Description of Functions). From time to
time during this task, I would benefit from viewing the code that
implements individual functions but have not been able to find that
code. Could somebody give me some hints please?
E.g., given the function CHITEST [1]:
1. I git grep for the function's name:
https://opengrok.libreoffice.org/search?project=core&full=CHITEST
2. I see opcode, like "{ "CHITEST" , SC_OPCODE_CHI_TEST },", and grep
for the opcode:
https://opengrok.libreoffice.org/search?project=core&full=SC_OPCODE_CHI_TEST
3. I see "ocChiTest = SC_OPCODE_CHI_TEST," in opcode.hxx, and grep gain
for it:
https://opengrok.libreoffice.org/search?project=core&full=ocChiTest
4. In an interprN.cxx, I see "case ocChiTest :", and go there to see the
name of function called when that opcode arrives:
https://opengrok.libreoffice.org/xref/core/sc/source/core/tool/interpr4.cxx?r=0ef5c475#4392
5. So I see the function name is ScChiTest:
https://opengrok.libreoffice.org/xref/core/sc/source/core/tool/interpr3.cxx?r=f853ec31#2797
This is possibly too long, but that's from the PoV of not knowing where
to look initially. Of course, you could also try shortcut searching for
ScFoo when looking for FOO function... (not always helpful). Anyway,
this shows the relevant pieces.
It would also help if I could view the code for the Function Wizard.
For any dialog, you look into its English UI, and grep for the strings
in it (choose specific enough):
https://opengrok.libreoffice.org/search?project=core&full=%22Function+result%22
Find the .ui file, and then grep for its name in .cxx files - you will
find the constructor creating the dialog or one of its tabs:
https://opengrok.libreoffice.org/search?project=core&full=%22formuladialog.ui%22
So likely you need to look in formula/source/ui/dlg/formula.cxx
That's how I do that. HTH.
