I am happy to try and help but you are need to going to be a bit more specific.Need some assistance creating a lua script to do multiple global replace on multiple strings.
Are you do the search and replace over a single file or multiple files
If it is multiple files, how are you deciding which files need to be processed
When you say multiple strings, are the search and replace patterns fixed and if so what is an example of one such typical pattern
If these patterns are not fixed where are you planning on getting them from
The difficulty is there are so many ways to achieve this and depending on answers to the questions above will determine which of these many approaches is the easiest.
Finally, if you need to do tens or hundreds of individual search and replace actions then it might be better to use a tool like SED to do this work.
It is easy to run tools from inside Zeus macros, so it might be a good idea to write a simple macro that just runs SED and lets SED do all the heavy lifting.
One file at a time.
In that case this is fairly straight forward.
The simplest way to do this is as follows:
But you could also implement this using this more long winded approach:
Code: Select all
function key_macro() use_regexp = 0 screen_update_enable() -- replace all text in current document replace_all("LA_", "NY_", use_regexp) screen_update() search_options_restore() end key_macro() -- run the macro
Code: Select all
function replace_text(search, replace) -- set the search and replace details set_find_text(search) set_replace_text(replace) -- replace all the items in the document while ReplaceNext() > 0 do end end function key_macro() screen_update_disable() -- save current search settings search_options_save() -- different scope options SCOPE_FORWARD = 0 SCOPE_REVERSE = 1 SCOPE_MARKED = 2 SCOPE_ENTIRE = 3 SCOPE_ALL = 4 -- set the search options set_search_option("Scope" , SCOPE_ALL) set_search_option("UseCase" , 0) set_search_option("WholeWord" , 0) set_search_option("RegExpress", 0) -- replace all text in current document replace_text("LA_", "NY_") search_options_restore() screen_update_enable() screen_update() end key_macro() -- run the macro
Can you instruct me how to do it for multiple open files please?
The macro below will do the replace across all open, named document files.
Code: Select all
function key_macro() screen_update_disable() screen_update_enable() use_regexp = 0 delimiter = '|' FULL_DETAILS = 1 -- get all current document files delimited by the pipe character all_files = document_files(FULL_DETAILS, delimiter) current_window = get_window_id() -- split the all the files into their individual file names for file_name in string.gmatch(all_files, "([^|]*)|?" ) do -- activate the file window if window_activate_name(file_name) then -- replace the text in current document replace_all("LA_", "NY_", use_regexp) end end -- restore the original window window_activate(current_window) screen_update() end key_macro() -- run the macro
