    I used this extension in former versions of LO (with satisfaction). Now (ver 7.4, Win 11) I can't even install it.
    The latest version of AltSearch is dated 2017 and was compatible with LO 5.3.

    I have long dreamed that there will be a proficient programmer who will continue the work of Thomas Bilek...

    Very old-fahsioned appearance, and crashed LO7.3 when I installed it, but 5* for functionality.
    Hard to credit that 'Preserve capitalization' is not an option in the regular Find/Replace dialog yet, but this extension makes replacing one word with another -- whether at the start if a sentence or not -- a cinch.

    Can't install! Suggestions?

    Add Extension(s):
    C:\Users\WGW\AppData\Roaming\LibreOffice\4\user\uno_packages\cache\uno_packages\lu189085z1mw0.tmp_\AltSearch.oxt does not exist.

    1.4.2 was working with Ubuntu 22.04 1 LTS when it suddenly uninstalled itself (the icon was gone from the toolbar).

    Now, if I try to install it (from the Extension Manager) I get the following error:

    Add Extension(s):
    /home/[...]/.config/libreoffice/4/user/uno_packages/cache/uno_packages/lu263155zk80.tmp_/4cc0f88b_altsearch.oxt does not exist.

    So I reset LO to factory settings, and I could install it.

    Thank you Tomas for this extension! I really wish it was fully integrated with LO (especially the list of saved replacements and the unifying of the replacement symbol which is presently different: $ LO and \ in Altsr).

    For some reason, some find/replace strings only work in the LO standard advanced search and replace.

    No matter the version, it won't start on Ubuntu 22.04, LibreOffice 7.3. It sends back this error message :

    BASIC runtime error.
    An exception occurred
    Message: ./basic/source/uno/namecont.cxx:118

    Works great. Thank you, Tomáši. :)

    Works great using libreoffice Version:
    If installed a green spyglass icon appears at the top left. Usage is nice because there is a drop down list of regex with descriptions of what they are doing.
    Sometimes a bit slow (on a text with >200 pages) - don't interrupt and just wait some minutes.

    I don't know if it's the new update or what, but this went from working like a dream to not working at all on the one thing I *need* it for (replacing all numerals in a selection with superscript numerals). It still does ordinary find and replace, just not that.

    • Erin Kretsmer Nov 29, 2021, 5:25 PM (18 months ago)

      Naomi, I don't know if this helps, but there are multiple releases available on this page. Perhaps you could uninstall, download an earlier version, and use the older version for your purpose.

    An extremely useful extension that I have been using for a long time with OpenOffice and LibreOffice. Thanks for this.

    The tooltip and menu item used to show "Alt. Najít a nahradit", so I patched "addon.xcu" to fix that. The country codes must be removed from the language codes, i.e. it must be "en" instead of "en-GB" etc., then the correct translation is displayed.
