Comment 1 Xisco Faulí 2018-05-30 10:08:41 UTC
I can't reproduce it in

Build ID: 1:6.0.4~rc2-0ubuntu0.16.04.1
CPU threads: 4; OS: Linux 4.13; UI render: default; VCL: gtk3; 
Locale: ca-ES (ca_ES.UTF-8); Calc: group

soffice --cat /home/xisco/Escriptori/Untitled\ 1.odt works for me!!

Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.

Comment 5 Luuk 2019-01-12 10:51:54 UTC
Sorry for later reply, and thanks to Xavier for posting that he has the same problem.

The problem is still there:
D:\TEMP>"C:\Program Files\LibreOffice\program\soffice.exe" --version

LibreOffice 9d0f32d1f0b509096fd65e0d4bec26ddd1938fd3

D:\TEMP>"C:\Program Files\LibreOffice\program\soffice.exe" --cat TEST.odt

D:\TEMP>"C:\Program Files\LibreOffice\program\soffice.exe" --cat TEST.ods


(TEST.odt will be uploaded soon, TESTods is the file I uploaded earlier )

Also converting from command-line works
"C:\Program Files\LibreOffice\program\soffice.exe" --convert-to pdf d:\temp\TEST.odt
Comment 8 Xisco Faulí 2019-01-14 10:01:41 UTC
Maybe a duplicate of bug 112536 which is fixed in master?
Could you please try to reproduce it with a master build from http://dev-builds.libreoffice.org/daily/master/ ?
You can install it alongside the standard version.
I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the master build

1. The problem of not getting any output on Windows is indeed tdf#112536, and is fixed now.

2. --cat does work for me with .odt files; when using with debug builds, one needs to consider the debug output that gets emitted by LibreOffice to stderr, and mixed with the output to stdout when seen in terminal; so the best way to see if something is actually output is using command line like

> soffice --cat path/to/file.odt > path/to/out.txt

so that out.txt would contain only the stdout data, while console would get all warnings/info from stderr.

3. --cat does *not* work for me with .ods; *possibly* that's expected that we only output the content for text documents, not other types of documents - I suppose we use "plain text" output filter for the loaded document, which would fail for spreadsheets.
Comment 10 Mike Kaganski 2019-01-14 10:25:08 UTC
Also please note that to use LibreOffice in console mode, after the fix for tdf#112536, you should *not* use the soffice.exe (which is GUI launcher); you should either omit the executable's extension, or use new soffice.com to have proper console mode (omitting the extension *by default* prefers .com over .exe in console - subject to PATHEXT environment variable [1]).

Comment 11 Mike Kaganski 2019-01-14 12:08:48 UTC
I confirm that --cat is implemented internally as setting output filter to "txt:Text", performing the usual conversion to a temporary file, and then putting the content of that temporary file to stdout. Thus, it only works for documents opened as text documents (i.e., using Writer component which has "Text (.txt)" output filter).

The wording of our help [1]

> Dump text content of the following files to console

could be improved to mention this limitation. So this should be changed to the documentation/help issue.
