Date Function Causes Segmentation Fault Crash

[RonHolt]

Version

I'm running version 0.8.4 built from source (because the latest version is not available yet in the apt-get repository, and I need multi-sheet functionality).

Segmentation Fault Crash

Specifically, I am experiencing the Segmentation Fault crash when I try to run the example date function from the documentation:
\"@date(@now, "%d/%m/%Y")

I get the error:
Segmentation fault (core dumped)

I ran sc-im with GNU Debugger to try to get a clue as to what could be causing the error. To be honest, I'm not too familiar with C programming / debugging, just thought it might help with the diagnosis.

Here was the output from gdb when I recreated the bug in an empty spreadsheet and then ran a backtrace:

[No Name]:{Sheet1}  A0 (10 2 0)                                                                                                                                                         -- INSERT --

General Date Functions Not Working

Less severe (because it doesn't cause a crash) is that when I try to run date functions in general, like:
\"@hour("1708588800")

Or if I run:
\"@now

I get the following error (without a crash):
error in slet - exprerr

Thanks!

As a vim user, I am constantly frustrated when using any other spreadsheet program. I super appreciate this project.

There are just a few things missing for me to be able to completely replace programs like LibreOffice Calc. (Maybe I need to become more familiar with Lua to extend.) Would love better support for conditional formatting (I know about the CELL_NEGATIVE style). Worried about the crashes, so I have to save manually often.

But this is an awesome project! Thanks for all the effort you've put into it.

@GitarMan confirmed. will take a look at it.

[andmarti1424]

@GitarMan Could you please update to latest commit on dev branch and retry? Thanks.

[RonHolt]

@andmarti1424 That fixed the segfault, thanks!!

Now when I run:
\"@date(@now, "%Y/%m/%d")

It successfully outputs the date.

I tested some of the other date functions though, and and I'm still getting the error in slet - exprerr error (without a crash).

All these date functions are throwing that error:
\"@tts(8,20,45)
\"@now
\"@year("1708588800")
\"@month("1708588800")
\"@day("1708588800")
\"@hour("1708588800")
\"@minute("1708588800")
\"@second("1708588800")

However, this function works as expected:
\"@date(@dts(1976, 12, 14))

@GitarMan hello. will check those commands. thank you.
