Symboltin v1.01

[DanKarron at UCBVAX.BERKELEY.EDU]

The next version of Symboltin, v 1.01 is on my anon ftp on karron.med.nyu.edu.

This is a suite of subroutines and a main driver that will read and
manipulate values in itself or a target program much like dbx/edge via
the symbol table and the /debug/ entries.

I have put in a subroutine that will printout the value of a structure
in c recompilable form.

Here is some example code and the output it produces.
This code writes a c subroutine as part of a larger code generator:

/*********************************************************************/  
#define P(q)	fprintf(dumpfile,"%s\n",q)
void WriteCPanel(Panel *p)
{
P(stars);
fprintf(dumpfile,"void def_panel%d() \n",PanelNumber++);
P("{");
P("Panel *p;");
P("Actuator *a;");
P("");
P("p=pnl_mkpanel();");
PrintStruct(dumpfile,p,"Panel","p");
P("\n");
}
/**********************************************************************/
Here is the output from PrintStruct();

You can control how much and what parts of a struct are dumped by putting
a dummy member in that will not print, but will keep the Symboltin
program from running down the rest of the struct. Usually a 
struct has a number of memory pointers that you don't want to 
print out. Group those after the stop_struct_print marker. 
Also, a flag is kept internally to not printout pointers that can
not be resolved to symbols, so you don't get output like this:

rb2->al=(void *)0x1000abcde;

This value is worthless in saving the external state of the struct.

/***************************************************************/
void def_panel0() 
{
Panel *p;
Actuator *a;

p=pnl_mkpanel();
p->x = 314;
p->y = 724;
p->w = 91;
p->h = 91;
p->minx = 0.800000;
p->maxx = 2.600000;
p->miny = 0.800000;
p->maxy = 2.600000;
p->cw = 0.000000;
p->ch = 0.000000;
p->ppu = 50.555550;
p->label = "panel three";
p->icon_label = NULL;
p->ExternName = NULL;
p->DoNotDumpMe = 0;


rb1=pnl_mkact(pnl_radio_button); 
rb1->x = 1.000000;
rb1->y = 1.000000;
rb1->w = 0.400000;
rb1->h = 0.400000;
rb1->lx = 0.500000;
rb1->ly = 0.050000;
rb1->lw = 0.720000;
rb1->lh = 0.300000;
rb1->ld = 0.040000;
rb1->val = 0.000000;
rb1->extval = 0.000000;
rb1->initval = 0.000000;
rb1->maxval = 1.000000;
rb1->minval = 0.000000;
rb1->scalefactor = 1.000000;
rb1->key = 0;
rb1->labeltype = 0;
rb1->initfunc = pnl_radio_button;
rb1->DansId = 0;
rb1->label = "cyan";
rb1->label_down = NULL;
rb1->label_up = NULL;
rb1->label_target = NULL;
rb1->label_min = NULL;
rb1->label_max = NULL;
rb1->scale_incriment = 0.000000;
rb1->scale_subdivision = 10.000000;
rb1->Volatile = 0;
rb1->ExternName = "rb1";
rb1->AttachName = NULL;
rb1->automatic = 0;
rb1->selectable = 1;
rb1->visible = 1;
rb1->beveled = 1;
pnl_addact(rb1 , p);

.... and so on, ad nausium.

You can edit these values, compile and redump. This is much easier than
making a special format file to save the values in all the struct fields.
As you change values,struct members, your code will evolve through each
dump/recompile/redump cycle.

Please let me know if you need any help using this: It is on my anon ftp
at karron.med.nyu.edu. My email to you answering your questions will
be the documentation I will distribute with the source code.

Enjoy!

Dan.
