Hi,

Howdy,


I would like to know if there exists roadmap that would allow to create
a server version of libreoffice that would execute macros job on office
docs. It would mean a version not using all the interface part of
libreoffice that would be much more compact. The goal would be to
process many files using remote services or on some files to automate
some processing such as creation of html files. Is there something
foreseen? Is it totally ridiculous? Has it been done and I do not find
the correct documentation?

First - redirecting the reply email to the User mailing list (the website
ML you originally posted to is for issues regarding the LibreOffice website
not the application).

Second - LibreOffice has always had the ability to run in what is referred
to as 'headless' mode. This means there is no GUI active while all the
document processing functions are available. The application even has
command line options specifically designed to take ODF files and generate
other fie types (html for instance) from them, in this non-GUI mode. This
feature is used as a backend for web applications today in production
environments. You can also call macros (sriptis) from the command line and
again if the macro is written properly can run just fine in this headless
mode.

Finally - I don't personally have a bunch of links for you with information
on setting that up but expect others on the users list will.

Best wishes,

Drew


Thanks in advance

Bruno

                       suitable for them.
   {file} {macro:///Library.Module.MacroName}
                       Opens the file and runs specified macros from
                       the file.

                       all other arguments.

General arguments:
   --quickstart[=no]   Activates[Deactivates] the Quickstarter service.
   --nolockcheck       Disables check for remote instances using one
                       installation.
   --infilter={filter} Force an input filter type if possible. For example:
                       --infilter="Calc Office Open XML"
                       --infilter="Text (encoded):UTF8,LF,,,"
   --pidfile={file}    Store soffice.bin pid to {file}.
   --display {display} Sets the DISPLAY environment variable on UNIX-like
                       platforms to the value {display} (only supported by a
                       start script).

User/programmatic interface control:
   --nologo            Disables the splash screen at program start.
   --minimized         Starts minimized. The splash screen is not displayed.
   --nodefault         Starts without displaying anything except the splash
                       screen (do not display initial window).
   --invisible         Starts in invisible mode. Neither the start-up logo nor

                       can be controlled, and documents and dialogs can be
                       controlled and opened via the API. Using the parameter,
                       the process can only be ended using the taskmanager
                       (Windows) or the kill command (UNIX-like systems). It
                       cannot be used in conjunction with --quickstart.
   --headless          Starts in "headless mode" which allows using the
                       application without GUI. This special mode can be used
                       when the application is controlled by external clients
                       via the API.
   --norestore         Disables restart and file recovery after a system crash.

                       fresh user profile and helps to restore a broken
                       configuration.
   --accept={UNO-URL}  Specifies an UNO-URL connect-string to create an UNO
                       acceptor through which other programs can connect to
                       access the API. UNO-URL is string the such kind
uno:connection-type,params;protocol-name,params;ObjectName.
   --unaccept={UNO-URL} Closes an acceptor that was created with --accept. Use
                       --unaccept=all to close all open acceptors.
   --language={lang}   Uses specified language, if language is not selected
                       yet for UI. The lang is a tag of the language in IETF
                       language tag.

Developer arguments:
   --terminate_after_init
                       Exit after initialization complete (no documents loaded).
   --eventtesting      Exit after loading documents.

New document creation arguments:
The arguments create an empty document of specified kind. Only one of them may
be used in one command line. If filenames are specified after an argument,
then it tries to open those files in the specified component.
   --writer            Creates an empty Writer document.
   --calc              Creates an empty Calc document.
   --draw              Creates an empty Draw document.
   --impress           Creates an empty Impress document.
   --base              Creates a new database.
   --global            Creates an empty Writer master (global) document.
   --math              Creates an empty Math document (formula).
   --web               Creates an empty HTML document.

File open arguments:
The arguments define how following filenames are treated. New treatment begins
after the argument and ends at the next argument. The default treatment is to
open documents for editing, and create new documents from document templates.
   -n                  Treats following files as templates for creation of new
                       documents.
   -o                  Opens following files for editing, regardless whether
                       they are templates or not.
   --pt {Printername}  Prints following files to the printer {Printername},
                       after which those files are closed. The splash screen
                       does not appear. If used multiple times, only last
                       {Printername} is effective for all documents of all
                       --pt runs. Also, --printer-name argument of
                       --print-to-file switch interferes with {Printername}.
   -p                  Prints following files to the default printer, after
                       which those files are closed. The splash screen does
                       not appear. If the file name contains spaces, then it
                       must be enclosed in quotation marks.
   --view              Opens following files in viewer mode (read-only).
   --show              Opens and starts the following presentation documents
                       of each immediately. Files are closed after the showing.
                       Files other than Impress documents are opened in
                       default mode , regardless of previous mode.
   --convert-to OutputFileExtension[:OutputFilterName]
     [--outdir output_dir] [--convert-images-to]
                       Batch convert files (implies --headless). If --outdir
                       isn't specified, then current working directory is used
                       as output_dir. If --convert-images-to is given, its
                       parameter is taken as the target MIME format for *all*
                       images written to the output format. If --convert-to is
                       used more than once, the last value of OutputFileExtension
                       [:OutputFilterName] is effective. If --outdir is used more
                       than once, only its last value is effective. For example:
                   --convert-to pdf *.odt
                   --convert-to epub *.doc
                   --convert-to pdf:writer_pdf_Export --outdir /home/user *.doc
                   --convert-to "html:XHTML Writer File:UTF8" *.doc
                   --convert-to "txt:Text (encoded):UTF8" *.doc
   --print-to-file [--printer-name printer_name] [--outdir output_dir]
                       Batch print files to file. If --outdir is not specified,
                       then current working directory is used as output_dir.
                       If --printer-name or --outdir used multiple times, only
                       last value of each is effective. Also, {Printername} of
                       --pt switch interferes with --printer-name.
   --cat               Dump text content of the following files to console
                       (implies --headless). Cannot be used with --convert-to.
   --script-cat        Dump text content of any scripts embedded in the files to console
                       (implies --headless). Cannot be used with --convert-to.
   -env:<VAR>[=<VALUE>] Set a bootstrap variable. For example: to set
                       a non-default user profile path:
                       -env:UserInstallation=file:///tmp/test

Ignored switches:
   -psn                Ignored (MacOS X only).
   -Embedding          Ignored (COM+ related; Windows only).
   --nofirststartwizard Does nothing, accepted only for backward compatibility.
   --protector {arg1} {arg2}
                       Used only in unit tests and should have two arguments.
