| I have been very happy with using Crimson Editor for editing MUSHclient script files, and in general.
It is:
- Free
- Fast
- Does syntax colouring of Lua (and various other languages, like C, HTML)
- Lets you do FTP editing (load and save from a FTP server), which is handy for grabbing files on another server
- Can be configured to show MUSHclient help for the word under the cursor (see below)
- Can be configured to show Lua help for the word under the cursor (see below)
- Can be configured to test Lua stand-alone by putting the path to lua.exe in its tools configuration, so you can edit/test/fix Lua programs very quickly
- Can be configured to syntax-colour the MUSHclient functions, so you can immediately see if they are spelt correctly (see below).
Below are links to the various tips I have developed for Crimson Editor over the years:

| To simplify syntax colouring MUSHclient keywords, here are the files I used for Crimson Editor:
http://www.gammon.com.au/files/mushclient/lua.key (15 Kb)
http://www.gammon.com.au/files/mushclient/lua.spc (1 Kb)
The first one has all the Lua keywords and functions, as well as the MUSHclient function names.
You can download these files and replace the ones of the same name in the Crimson Editor "spec" subdirectory.
I generated the function names with this script:
pairsbykeys = require "pairsbykeys"
for _, t in ipairs {"math",
"io",
"debug",
"coroutine",
"os",
"string",
"table",
"package",
"world",
"utils",
"bit",
"bc",
} do
for k, v in pairsbykeys (_G [t]) do
if string.sub (k, 1, 1) ~= "_" then
print (t .. "." .. k)
end -- not starts with underscore
end -- each function
print ""
end -- each major package
-- now global variables
for k, v in pairsbykeys (_G) do
if type (v) == "function" or type (v) == "string" then
print (k)
end -- function or string
end -- each function
Then I copied all the "world.xxx" functions to have a second copy without "world." in front, as MUSHclient does not require the world prefix, for simplicity. (Basically this is done by putting a metatable on the _G table).

| A slightly improved version finds for itself all the table names:
require "pairsbykeys"
for a, b in pairsByKeys (_G) do
if type (b) == "table" and a ~= "_G" then
for k, v in pairsByKeys (_G [a]) do
if string.sub (k, 1, 1) ~= "_" and type (v) == "function" then
print (a .. "." .. k)
end -- not starts with underscore
end -- each function
end -- each table
print ""
end -- each major package
-- now global variables
for k, v in pairsByKeys (_G) do
if type (v) == "function" or type (v) == "string" then
print (k)
end -- function or string
end -- each function
After running this a few extra function names cropped up (eg. progress.new) so I have uploaded a more up-to-date lua.key file. |

| using the 'progress.new' function just shows a progress dialog that does not allow you to dismiss it, so use of it is pointless as of yet.

| Well, it was designed for use in the spell checker, and it *can* be dismissed, however in version 4.26 or earlier it has a bug which I just noticed, so I wouldn't use it just yet. Here is an example of how it might be used:
dlg = progress.new ("Self-destruct sequence started ...")
number_of_things = 100000
dlg:range (0, number_of_things )
dlg:setstep (1)
for i = 1, number_of_things do
dlg:step ()
dlg:status ("Doing item " .. i)
if dlg:checkcancel () then
print "Self-destruct sequence cancelled..."
break
end -- if
end -- loop
dlg:close ()
This illustrates the general idea of the progress dialog.
- You create it with progress.new - that gives you a userdatum which is used for subsequent operations.
With the userdatum (dlg in this example) you can:
- dlg:range - set a range for the progress bar (assuming you know that you need to do x things)
- dlg:setstep - set a step amount - when you step it goes up by this much.
- dlg:status - set the status (which is shown in the progress bar) - this is a piece of text
- dlg:step - step up to the next item
- dlg:checkcancel () - check if they clicked "cancel"
- dlg:close - close and dismiss the dialog
Notice the colon after "dlg", not a period. This is because it is a userdatum.
Thanks to your message I noticed that there is a bug, after you close it, when Lua goes to garbage-collect it (which might be 5 minutes later) it raises an error. Better wait for version 4.27 before you try it.
