How to compile & Run freebasic code

Postby kcvinu » May 02, 2021 10:26

Hi all,
I am using VS Code to write freebasic code. I am able to compile my code in vs code, with the help of an extension called "code-runner". But I need to compile & run my code when I click the run button on vs code. I checked the fbc manual for a compiler switch but didn't find. Please help.

I dowloaded a .zip version of VS Code.
Nice editor but I note that (under configuration for code-runner):

"Make sure the executor PATH of each language is set in the environment variable"

So that is me stopped, my fbc.exe in use is not on a system path.
Good luck.

@dodicat,
So you mean, there is no compiler switch for running program right after compiling ?

They are not really taylored for any particular editor, they are for the command line.
OK, ide's can be set with them for the reasons as shown, an ide just passes the command line instructions to the compiler.
you can do some things inside your code, e.g. set a temporary path to your compiler.

Code: Select all


dim as string mypath="C:\Users\Computer\Desktop\fb\FreeBASIC-1.07.2-win64\FreeBASIC-1.07.2-win64"

SetEnviron "path="+mypath
print

print
shell "fbc.exe"
sleep

you could probably make a batch file that would invoke fbc.exe and then after successful compile run the executable if it was produced, you will have to do a bit of searching but it should be doable, your IDE would invoke your batch file instead of fbc.exe

Hi kcvinu,
There are many ways to do it with a batch file, this is just one example:

Code: Select all

@echo off
set options=-gen gcc -Wc -O2 -s console
if exist %~pn1.exe del %~pn1.exe

set path=C:\TDM-GCC-64\bin\
echo *** compiling %~nx1 with %options% ***

set rcfile=
if exist TmpFb.rc set rcfile=TmpFb.rc

<your path>FreeBasic\fbc64.exe %options% %rcfile% "%1"
echo.
if exist %~pn1.exe (
   echo *** running %~n1.exe %2 ***
   start %~pn1.exe %2
) else (
   echo *** you got a problem, %~pn1.exe was not created ***
)
First argument is the path as you drag it over the *.bat file, e.g. C:\mypath\myfile.bas
Second argument is what you pass to the running executable (if needed).

Thank you all for the replies.
@jj2007,
I failed to run your bat file. However, that bat file idea gave me a new direction and I created this AutoIt script for that.

Code: Select all

Local $FileName = $CmdLine[1] '\\ First command line parameter
Local $WorDir = $CmdLine[2]
Local $compRes = ShellExecuteWait ("fbc", $FileName & ".bas", $WorDir)
If $compRes = 0 Then
   ShellExecuteWait($FileName, "", $WorDir)
Else
   MsgBox(0, "FbcRunner", "Compilation Failed...!!!")
EndIf
Exit

Now, all I need writhe vs code settings like this.

Code: Select all

"freebasic" : "FbcRunner $fileNameWithoutExt $dirWithoutTrailingSlash"

Though, It's a success but there is a problem in this approach. If compilation failed, I didn't get any error messages. Because, ShellExecuteWait only returns the exit code of the running program aka fbc. So I think I need to take this little script to another level.
For that, I am planning to create a little program in VB.Net since it is the only language I know how to work with processes. In VB.Net, I can use the process class and get the error messages which fbc emits.

Hi all,
This is a ThinBasic script for this purpose. It will get the file name and working directory from cmd args and run the fbc compiler. Then if any errors occurs, It will show the fbc error message in cmd window. If compilation is success, It will run the new exe file and display the program results in cmd window. I am posting the script because some will get benefit from this.

Code: Select all

Uses "Console"
Uses "OS"
 

Dim rawFileName As String = OS_GetCommand(1)  '\\ Here we get the first cmd args
Dim LastCmd as String = OS_GetCommand(0)   '\\ this is a hack bcz, thinbasic won't read a quoted string.So we get the full args.
Dim WorkingDir As String = GRAB$(LastCmd, Chr$(34), Chr$(34)) '\\ Now we grab the string in between two quotes

Dim BasFile As String = rawFileName
Dim ExeFile As String = rawFileName & ".exe"
Dim SQuote As String = Chr$(34)
Dim QuotedBasFile As String = SQuote & BasFile & SQuote
Dim QuotedExeFile As String = SQuote & ExeFile & SQuote
Dim QuotedWorDir As String = SQuote & WorkingDir & SQuote
Dim FbcPath As String = "C:\FreeBasic\FreeBASIC-1.07.3-win64\fbc.exe"
Dim QuotedFBC as String = SQuote & FbcPath & SQuote
Dim FullFile As String = WorkingDir & "\" & BasFile
Dim QuotedFullFile as String = SQuote & FullFile & SQuote
Dim QuotedFullExe As String = SQuote & WorkingDir & "\" & ExeFile & SQuote

Dim pID = OS_Shell(QuotedFBC & " " & QuotedFullFile, %OS_WNDSTYLE_NORMAL, %OS_SHELL_SYNC) '\\ here is the compilation
'\\ The magic is here, If compilation ends up in an error, thinbasic will show us the results.
if pID = 0 Then '\\ Exit code = 0 then run the generated exe file.
  OS_Shell(QuotedFullExe, %OS_WNDSTYLE_NORMAL, %OS_SHELL_SYNC)
EndIf
WaitKey

Funny name for this function, I had to google it to confirm it's really part of the language. My own baby is called Replace$()

Did your adjust your paths? I see no other reason why it should fail...

@jj2007,
Yeah, Grab is a funny name. But it's very handy.
I have completed that script and started using it in my laptop & PC. Now I can code FreeBasic in VS Code.

I have changed the path but my path contains some spaces. I think that was the reason. I know very little about vb script but I was sure that I can solve that problem with languages like AutoIt, ThinBasic, Vb.Net, Nim.
BTW, I see your Replace implementation in MasmBasic. Is it active now ? I have an urge to learn those languages which have basic in name or syntax.

@kcvinu
would you care to share how you managed to setup VScode to compile for FB?
no matter what I tried I could never get it to work

Since October 2009, yes ;-)

Sure.
1. Install lang-freebasic extension by mudhairless.
2. Install Code Runner extension by Jun Han
Now you need to tweak some options of Code runner.
1. Open VS Code Settings.
2. Open JSON Settings page
3. Find "code-runner.executorMap"
4. Add a new value like this -
"freebasic" : "FbcRunner $fileNameWithoutExt $dirWithoutTrailingSlash" // Here, FbcRunner is my program.
5. Find ""code-runner.executorMapByFileExtension"
6. Add a new value like this -
".bas" : "FbcRunner $fileNameWithoutExt $dirWithoutTrailingSlash"
7. Find this -- "code-runner.languageIdToFileExtensionMap"
8. Check if this value is there -- "freebasic" : ".bas". (If not, add it)
9. Now find this -- "files.associations"
10. Add this value -- "*.bas": "freebasic"
That's all.

@jj2007,
I 've heard about HLA (High Level Assembly) programming language few years ago. I don't know what's status of it. But it was a nice blend of assembly and high level features.
1. MasmBasic is not BASIC: mov ebx, eax is not part of any BASIC dialect.
2. MasmBasic is assembly, i.e. it will flawlessly assemble with Microsoft Macro Assembler (MASM, version 6.15 upwards) or, alternatively, with Jwasm

I took this warning seriously :)
