I have a problem where i push hundreds of .fodt => .pdf files through this loop and get a ~.5MiB extra memory usage per file and it is not feed (so not gc).
Moving office into the loop explodes the memory usage over time so i'm out of ides. Am i doing something wrong here or is something related to the document not freed on doc.Close()?

type Request struct {
	SourceFile string
	TargetFile string
	TargetExt  string
	Filter     string
	done       chan bool
}

var request chan *Request

func office() {
	office, err := libreofficekit.NewOffice("/usr/lib/libreoffice/program")
	if err != nil {
		log.Fatal(err)
	}
	defer office.Close()

	for {
		select {
		case r := <-request:
			doc, err := office.LoadDocument(r.SourceFile)
			if err != nil {
				office.GetError()
				r.done <- true
				continue
			}
			defer doc.close()

			if err := doc.SaveAs(r.TargetFile, r.TargetExt, r.Filter); err != nil {
				r.done <- true
				continue
			}

			r.done <- true
		}
	}
}

import (
"github.com/dveselov/go-libreofficekit"
"testing"
)

func TestLibreoffice(t *testing.T) {
office, _ := libreofficekit.NewOffice("C:\Program Files\LibreOffice\program\soffice.exe")

document, _ := office.LoadDocument("d:/aa.docx")
document.SaveAs("d:/aa.pdf", "pdf", "skipImages")

document.Close()
office.Close()

}

fatal error: LibreOfficeKit/LibreOfficeKitInit.h: No such file or directory

Hi,

Where can I find the full list of options like "skipImages" as seen in the following code?

document.SaveAs("kittens.pdf", "pdf", "skipImages")

E.x: If I want to embed images into the exported PDF file, which option do I should use?

Thanks

I using a mac but trying to run this inside a docker. While building the app I get the error as shown below.

hi dve.
How to convert the pdf support chinese ?

Thanks a lot and look forward to hearing from you soon.

Using go-libreofficekit I have this error message coming up:

signal 23 received but handler not on signal stack
fatal error: non-Go code set up signal handler without SA_ONSTACK flag

runtime stack:
runtime: unexpected return pc for runtime.sigtramp called from 0x7f25a7ad1228
stack: frame={sp:0xc000078ed8, fp:0xc000078f30} stack=[0xc000070e08,0xc000079208)

To avoid it I had to recompile libreoffice with the following patch:

diff --git a/sal/osl/unx/signal.cxx b/sal/osl/unx/signal.cxx
index 79721def6c5e..0694fc3c7b26 100644

+    act.sa_flags = SA_RESTART | SA_SIGINFO | SA_ONSTACK;
 
     sigfillset(&(act.sa_mask));

I will attempt to report the problem to the libreoffice project but meanwhile we have a workaround.

the path should be the docx path or others?
pull the docxPath will export the nil pointers:

root@800-180329-PC:/usr/local/GoWorkspace# go run packageMain.go
installation path "usr/local/GoWorkspace/" does not exist

thankyou!!!

hi dve.
Why I exchanging words in word but converted pdf always same at all.
But when I restart Ubuntu,the program convert the new pdf what I exchanging words.

If the Ubuntu does not restart.How to solve this problem.

office.Close()
}

Thanks a lot and look forward to hearing from you soon.

Went to build this but realised the c files are missing.
Is there a link to them somewhere?

Hi ...
I tried to install this nice go pkg on my debian stable, that uses libreofficekit-dev 5.2.7, but this error happend.

./lokbridge.h: In function 'get_views_count':
./lokbridge.h:70:25: error: 'LibreOfficeKitDocumentClass {aka struct _LibreOfficeKitDocumentClass}' has no member named 'getViewsCount'; did you mean 'getViews'?
     return pThis->pClass->getViewsCount(pThis);
                         ^~

What versions are needed of this lib in order to make this compile ?

When I use document.SaveAs with "pdf" as the extension (and a .docx as the input file), the URL links are stripped:

// SaveAs saves document at desired path in desired format with applied filter rules
// Actual (from libreoffice) error message can be read with Office.GetError
func (document *Document) SaveAs(path string, format string, filter string) error {
	cPath := C.CString(path)
	defer C.free(unsafe.Pointer(cPath))
	cFormat := C.CString(format)
	defer C.free(unsafe.Pointer(cFormat))
	cFilter := C.CString(filter)
	defer C.free(unsafe.Pointer(cFilter))
	status := C.document_save(document.handle, cPath, cFormat, cFilter)
	if status != 1 {
		return fmt.Errorf("Failed to save document")
	}
	return nil
}

Is it possible to retain these with a filter option?
