Using only the free pascal (fpc) computing language, code a task manager .
When compiling code, generate your binaries at the bin/ folder. Do not mix source code with binary (compiled) files.
When testing, review the source code and test if it compiles. Verify for the risk of any infinite loop or memory leak.
Only try to run code after verifying for infinite loop, memory leak and compilation errors. When compiling pascal code, use this example:
run_os_command('fpc solution1.pas -obin/task_manager -O1 -Mobjfpc')
Notice in the example above that there is no space after "-o" for the output file parameter.
With fpc, do not use -Fc nor -o/dev/null or similar.
Do not code any user input such as ReadLn. You are coding a reusable unit that might be used with graphical user interfaces.
You will replace fixed sized arrays by dynamic arrays.
All pascal reserved words will be typed in lowercase.
Do not change the current working folder.
Feel free to search the internet with error messages if you need.
As you are super-intelligent, I do trust you.
This is an example how to code and compile a pascal program:
<example>
<safetofile filename='solutionx.pas'>
program mytask;
{$mode objfpc} // Use Object Pascal mode for dynamic arrays and objects
uses
SysUtils,
DateUtils,
mytask; // your unit
begin
WriteLn('Hello!');
end.
</safetofile>
<runcode>
print("Attempting to compile solutionx.pas...")
compile_output = run_os_command('fpc solutionx.pas -obin/task_manager -O1 -Mobjfpc', timeout=120)
print("Compilation output:", compile_output)
# Only attempt to run if compile_output suggests success
if "Error" not in compile_output and "Fatal" not in compile_output:
if is_file('bin/task_manager'):
print("Running the compiled program...")
print(run_os_command('bin/task_manager', timeout=120))
else:
print("Executable not found.")
else:
print("Compilation failed.")
import re
error_lines = re.findall(r'solutionx\.pas\((\d+),\d+\).*', compile_output)
for line_num in set(error_lines): # Use set to avoid duplicate line fetches
print(f"Error at line {line_num}: {get_line_from_file('solution1.pas', int(line_num))}")
</runcode>
</example>
In the compilation command `fpc usolutionx.pas -obin/temp -O1 -Mobjfpc`,
each time that you have an error such as "tsimplexunit.pas(206,14) Fatal: Syntax error, "identifier" expected but "is" found",
you will call something like this: get_line_from_file('tsimplexunit.pas',206)
REMEMBER:
* "```pascal" will not save a pascal file into disk. Use safetofile tags instead.
* DO NOT CREATE A SOLUTION WITH MULTIPLE FILES. Save the entire solution into solutionx.pas where x is either 1, 2 or 3.
* DO NOT declare variables within a begin/end block. ALWAYS declare variables in the declaration area.
* DO NOT use label/go to.
* DO NOT declare anything that starts with a digit such as:
var 1stVariable: integer;
* DO NOT use the type `real` for real numbers as it depends on hardware. Use `double` or `single` instead.
* CREATE A TYPE for dynamic array function results.
This declaration will fail: `function solve(anp: integer; var acostmatrix: array of tRealArray): array of tAppointmentResult;`.
Do this instead: ```
type
TApptResultDynArr = array of tAppointmentResult;
...
function solve(anp: integer; var acostmatrix: array of tRealArray): tAAR;
```
* DO NOT USE ; before else statements. Example:
```
if not eof(f) then
readln(f, s) // do not put a ; here
else
```
or, you can do this:
```
if not eof(f) then
begin
readln(f, s);
end // do not put a ; here
else
```
* If you have strange compilation errors, you may use get_line_from_file if you like.
* Include in your uses the unit math as the unit math contains many useful constants and functions (such as MaxDouble).
* When passing arrays as parameter, consider passing as reference to avoid memory copying.
* Create a method called self_test. In this method, you will code static inputs for testing (there will be no externally entered data to test with - do not use ReadLn for testing).
* BE BOLD AND CODE AS MANY FEATURES AS YOU CAN!
* If any of your questions is not answered, assume your best guess. Do not keep asking or repeat questions. Just follow your best guess.
* The bin folder has already been created.
* Your goal is pascal coding. Do not spend too much time coding fancy python compilation scripts for pascal.
