If you use only letters of the Latin alphabet, then everything is very simple: ```lua local s = geany.selection() if (s ~= nil) and (s ~= "") then geany.selection(string.upper(s)) end ``` ```lua local s = geany.selection() if (s ~= nil) and (s ~= "") then geany.selection(string.lower(s)) end ``` ```lua local s = geany.selection() if (s ~= nil) and (s ~= "") then local s1= string.upper(string.sub(s, 1, 1)) local s1 = string.lower(string.sub(s, 2, -1)) geany.selection(s1 .. s2) end ``` ```lua local s = geany.selection() if (s ~= nil) and (s ~= "") then s = string.gsub(string.lower(s), "^(%w)", string.upper) s = string.gsub(s, "([^%w]%w)", string.upper) geany.selection(s) end ``` If you need support for other languages, then everything becomes interesting. UTF-8 support is required, [for example](http://lua-users.org/wiki/LuaUnicode). I use [luautf8](https://github.com/starwing/luautf8) in the scripts folder + ```lua local a if (geany.dirsep == '/') then a = '?.so'; -- Unix else a = '?.dll'; -- MS Windows end

local sf = geany.dirname(geany.script) local p = sf .. geany.dirsep .. a if not string.find(package.cpath, p) then package.cpath = package.cpath .. ';' .. p end

local utf8 = require "lua-utf8"

local s = geany.selection() if ... ``` and so on...

These scripts apply to selected content within a document and then deselect that content after script is applied. Would it be possible to have that content remain selected after the script is applied?

I looked through the GeanyLua documentation a little and did not really see anything about keeping items selected after.

If this is possible, I like both, with and without selection after script is applied. If there is a way to achieve this with a simple code that can be added to each tool you have provided, can you show me one of them with this as an example so I can apply that "stay highlighted" code to each of them.

Still confused about what Lua can do with command line commands / bash shell scripts, I updated my other post with this "with selection" and "without selection" information as well, if interested #4070.

Thank You

@Skif-off Okay first, thank you for your continued help. That is okay about the capitalize first letter tool if you cannot find a suitable algorithm, at least it works on single lines.

RESTORE SELECTION For the “restore” selection, I might not have applied this right but I tried adding the code provided to the top and also tried adding to the bottom of one of the case tool scripts and I received the following error dialog ``` Lua script error: <path-of-script>/<script-name.lua>:3: unexpected symbol near '...' ``` (the number :3: is the line it shows up on so that changes depending on where this code is added to)

Thank You

P.S. Also thank you for mentioning the “restore” not “remain”. I like when you do stuff like this, just lets me know what the script is actually doing to achieve what I am looking for, which is good to know, thank you.

@Skif-off Thank you for your response, no problem. Okay, these all works now. Thank you so much for working on these, they work great :)

For any users interested in using these tools in the future, here are the final versions below.

Keep in mind that these methods will work with Latin letters only and it's not very convenient.
