Cannot compile "put"

mount "/sd", _vfs_open_sdcard()

dim r,test as ulong
chdir("/sd")       ' set working directory
open "/sd/testfile" for output as #3
put #3,0,test,1,r
close #3

The result:

Could be that the pos parameter needs to be a '1' or greater...

The flexprop BASIC language description of put includes "starting at position pos in the file (where pos is 1-based)"

put #handle, pos, var [,items [,r]]
put is used to write binary data to the open file whose handle is
handle, starting at position pos in the file (where pos is 1-based).
The position is optional, but if omitted a comma must still be
placed to indicate that it is missing. var is the variable containing
the first binary data to write, and items is the number of variables
to write starting at var. items is often omitted, in which case only 1
item is written. Note that the total number of bytes written is items
times the size of each variable.

Try:

put #3,1,test,1,r

OR

put #3,1,test,r    <== if there's only 1 item, no need to state that

Just a guess, really!

I tried

put #3,1,test,1,r

and

put #3,,test,1,r

with the same result

error: Unsupported operator 0x0

Did you try?:

put #3,1,test,r    <== check your commas

This compiled for me with flexprop version 5.9.8...

mount "/sd", _vfs_open_sdcard()

dim r,test as ulong
chdir("/sd")       ' set working directory
open "/sd/testfile" for output as #3

'put #3,0,test,1,r   <== commented out
put #3,1,test,r      ' added
close #3

What flexprop version are you running?

ersmith · 2022-02-23 14:26

There's a bug in the setting of the put/get result value. Either leave the result off, or else use the current github source code which has this fixed.

Thanks for the bug report,

pik33 · 2022-02-26 09:44

I compiled the newest version - Prop2Play stopped to do the directory/file list. I had to return to older Flexprop, which can compile working prop2play. If I manage to catch the error using the simple example, I will put it here.
Edit: the bug can actually be in prop2play, but the older Flexprop can make it work as expected while the new Flexprop cannot - I am now testing simple examples to catch the problem.

pik33 · 2022-02-26 14:34

I got lost. Simple examples work, the player does not. What is weird, is - in the player:

  close #5                                      ' todo: react to other errors (message box?)
  open currentdir$+"dirlist.txt" for output as #5
  print #5,".."+space$(36)                              ' this file system has no .. - it needs to be manually added
  filename$ = dir$("*", fbDirectory)                            ' find all directories
  while filename$ <> "" andalso filename$ <> nil
    if len(filename$)<38 then filename$=filename$+space$(38-len(filename$))     ' the string has to be exactly 38 characters 
    filename2$=right$(filename$,38)                         ' which enables to use get when reading
    print #5, filename2$    
 '   print filename2$                             ' write directory name to the file)
    filename$ = dir$()
  end while
  close #5

I commented out opening #0 in the player, so I used standard system print to serial terminal for testing this

If I uncomment the line "print filename2$" the loop works and the directory list is saved to a file and printed on ANSI termina;
If I comment the "print filename2$" line as in this code block, it lists only first directory element to the file.
The next step: compile with old and new flexprop, compare the lst files.

Edit: lists are different:

new:

01af8                 | LR__0048

Instead of __basic_dir we have now __system__basic_dir... to be continued...

pik33 · 2022-02-26 15:43

I gave up.

My "old" flexprop that compiles running version of prop2play is Version 5.9.9-beta-HEAD-v5.9.7-19-g1c955d38 Compiled on: Feb 12 2022
My "new" flexprop that compiles not fully working prop2play is Version 5.9.9-HEAD-v5.9.7-33-g89e95693 Compiled on: Feb 26 2022

I don't know what changed and what can make such difference. The workaround is to continue with the "old" version

JRoark · 2022-02-26 15:54

Does changing the optimization level change the behavior?

Given you seem to be compiling the compiler yourself, try the git bisect command on the spin2cpp repository. That lets you find the change that causes your issue. Basically, you'd do

git bisect start
git bisect bad HEAD
git bisect good 1c955d38

and then it checks out some in-between version for you. Compile that with

make clean
make

and test with the built compiler. If it works, git bisect good, else git bisect bad. It will then check out another version, etc, repeat until it has found the commit of interest. Then git bisect reset to return the repository to a clean state.

pik33 · 2022-02-26 16:43

I will try to do this git thing (which I didn't know of yet).

Does changing the optimization level change the behavior?

I compile with -O1. O2 gives garbage.:

error: Internal error exceeded local register limit, possibly due to -O2 optimization needing additional registers or code being too complicated

Without optimization the code is way too huge (256 K or something like this). It is already way too huge with -O1 but I will consider a size optimization when all basic things can work. Now it is still at alpha stage.

    move BASIC declare lib functions into the system module

 Changelog.txt           | 3 ++-
 doc/basic.md            | 2 ++

 3 files changed, 6 insertions(+), 3 deletions(-)

pik33 · 2022-02-26 17:40

So, yes, that was the change which made the difference.

What I did, was:

delete all Flexprop related files and directories
git clone the newest Flexprop
edit frontends/basic/basic.y reverting the changes in lines 1941 and 1981 from

DeclareFunction(systemModule, rettype, 1, funcdef, body, attrib, $1);

back to

DeclareFunction(current, rettype, 1, funcdef, body, attrib, $1);

Then after make install.. it works

The question is: why this change made this difference

ersmith · 2022-02-26 23:28

I've made some changes just now that might help your situation. The root problem is that some functions are being duplicated in the system and main modules.

pik33 · 2022-02-27 09:07

It works, but dir$("*", fbNormal) still lists also directories, which I think it shouldn't do as there is no way to get a list of files only. This is now not a problem, I know where to add the patch.

        if (oldattrib != 0) {
            r = stat(ent->d_name, &sbuf);
            if (r) {
                // error in stat, break
                return "";
            }
            mode = sbuf.st_mode & S_IFMT;
            attrib = 0;
            if (ent->d_name[0] == '.') {
                attrib |= fbHidden;
            }
            if (0 == (sbuf.st_mode & (S_IWUSR|S_IWGRP|S_IWOTH))) {
                attrib |= fbReadOnly;
            } else if (mode != S_IFDIR) {
                attrib |= fbArchive;
            }
            if ( mode == S_IFDIR ) {
                attrib = fbDirectory;
            } else if ( mode == S_IFCHR || mode == S_IFBLK || mode == S_IFIFO) {
                attrib = fbSystem;
            }
            if ( 0 == (attrib & oldattrib) ) {
                continue;
            }
