 Posted: Sun Feb 16, 2020 8:06 pm Post subject: REQUEST: LUA - Create form from string |
 |
|
I would like to embed forms in my lua library to make it easier to use. The CE designer is great and has some things that are hard or impossible to do with pure LUA commands. The helpers I I found to convert to LUA didn't work. I would love it if I could do something like:
1. (optional) From form designer, click 'Copy To Clipboard', which will copy something like the xml for a FRM file
2. Method createFormFromString(str) which would work like createFormFromFile(fileName) and take either the file contents straight from FRM, or just the binary part.
Right now I'm creating the file first and calling createFormFromFile()...
| Code: |
local formStringClass = '<?xml version="1.0" encoding="utf-8"?><FormData><formMonoClass Class="TCEForm" Encoding="Ascii85">...
local formStringImage = '<?xml version="1.0" encoding="utf-8"?><FormData><formMonoImage Class="TCEForm" Encoding="Ascii85">...
local formStringSearch = '<?xml version="1.0" encoding="utf-8"?><FormData><formMonoSearch Class="TCEForm" Encoding="Ascii85">...
function saveForm(name, text)
local path = getCheatEngineDir()..[[\autorun\forms\]]..name
local f, err = io.open(path, "w")
if f == nil then return nil, err end
f:write(text)
f:close()
return true
end
saveForm('formMonoClass.frm', formStringClass)
saveForm('formMonoImage.frm', formStringImage)
saveForm('formMonoSearch.frm', formStringSearch)
formMonoClass = createFormFromFile(getCheatEngineDir()..[[\autorun\forms\formMonoClass.frm]])
formMonoImage = createFormFromFile(getCheatEngineDir()..[[\autorun\forms\formMonoImage.frm]])
formMonoSearch = createFormFromFile(getCheatEngineDir()..[[\autorun\forms\formMonoSearch.frm]])

i'll look into it, but why not just create a package with relative paths?
i'm sure your library exists out of more than one lua file, so you can just as easily include the .frm files in the package as well.
example:
https://github.com/cheat-engine/cheat-engine/tree/master/Cheat%20Engine/bin/autorun/ceshare
maintenance of the frm files is a lot easier than editing the text in a lua file
(in the formdesigner you can click file-load and save, it doesn't have to be in a table)

My attempt.
| Code: |
-- sample directory for *.frm in development
local root = [[C:\Users\username\frmpath]]
-- utilities
local psep = package.config:sub(1,1)
local cat = table.concat
local function catPath(...)
return (cat({...},psep):gsub("[/\\]+",psep))
end
FRM_IO = {
quoteFRM = function(fn)
local f = io.open(fn,'rb')
local s = f and f:read"a",f and f:close()
return s and "'"..s:gsub("['\\\0-\31\128-\255]",function(c)
return string.format([[\x%02X]],c:byte())
end).."'", s and s:len()
end,
fromString = function(s, loader)
local tmpdir = os.getenv"TEMP" or os.getenv"TMP" or "."
local tmpfn = cat{'_',math.random(100000,999999),os.time()}
tmpfn = catPath(tmpdir, tmpfn)
local f = io.open(tmpfn,'wb')
local ok = f and f:write(s) and true,f and f:close()
return ok and (loader or createFormFromFile)(tmpfn), os.remove(tmpfn)
end
}
-- make quoted string of the *.FRM file
local quoteStr,len = FRM_IO.quoteFRM(catPath(root,"SavedFormTest.FRM"))
--- print(quoteStr) and c & p quoteStr in source
local frmStr = '<?xml version="1.0" encoding="utf-8"?>\x0D\x0A<FormData>\x0D\x0A <UDF1 Class="TCEForm" Encoding="Ascii85">(6Znl):Zgron(+8wVQx3$[prLz,ghtT0lYw5N*//NV]-@8A9CTuBHu3/0(y;0;KNPgO7v67vdeq(Yh/1Djs-pY#$#V_NPJK]8f_jyVcxK,vZl2c!Qbeo6YLX4t]ISFEZT5cCSyBLrH0q6XiRYePMTLU-::cCOV-uaUr*an}sfL8e5k^KQb.iiA(ebKJqL}*pC8$diKuTt^,%i=Gm373,3NB?9m*hhOmwLWPs-QNXw;2eRb}r$szJ:*NwG-Shy_ZVn,,x;ZQ7S*F,.0cX1H=y2%!L#8GGWKe@ajN?m$f.;nV@Ws+UMG^_Z7Le=Z]RUP=WgHTEam1OoH2sZ7*I(o{Du}*sE7;QNIQH1lkT^w6dMBLXncll0.y)Ou[fnS/M$7{_o/6wb]j)JQPIu;q#R^uzeWq-zcd^Hr_;{9QGFRLYKZPeNKy4aIt5Qt*^Yg1J.g@Xk01)?UcLW-KjE/L#Ti,PKogrty:yu/-XA*sGiG$4;14$QRiDTOPjbJVTY=%uohbmjVuw;Q@r-G2A:%fr/tkCwmH8_G#)rCHdqDDtShth3J?=DlA127u$*#RH.;W?/bU-YFFryC27^Se]Nd9Ns3!dnv?bH=jWacWf8=;lXEFx93YRA[Oa;@8p]GBRug#BUBh%F@u8#jK?ZFKDeAVN*b%kTu/9%KoxpQU?=:J7MwGTAP[cIh4Y3Xkg#5?3U$L@,eb5.4)r@lK1jCr+{yAK;5d@V1ufs_4P0RBLnSh@4S1FHnH/@o;M%jV@GuQ%O_AwmB3+J9:XhU.Gl:CryuwF^^KBPB;N(p)cDt$nL]u_eXVt(JQ+aN5bPFWJ^z/N)+YPj9([W*_H((l},O{P*Y0.OSN/Hd6(su)I)e04Hz.uX?8z0%lxPCNN=^=V:F}_Y{I+Um3@yp*^XF+J6ld*Xk:Lnxbd3Q+PO=FM=nW16Tio!{/Eaoh7_MJMl3sZ%do/2[].Z69I=H14+o:8SMU/tgGIsquPlQ%s5oKJP{$?!,t#ghTfDN8)Jm87@D^fNyyqj)T5oljUO.zdg^0Dsp;h006UG5?9Z(Qd{tFQshl8YxfN^1-J.ZDhf[nW}^=?-/X#T#-.4Q$y9p*(aF}j3?ke3yQ3Ubk-uPIYE)iraG+WeTjGuh^T*L?kpWmBc-)plqT!5b.s[xDn!m6ad8e;qO+%@Tc3J{y?3AuE./#f%h[Su6}jvT0Q+dn!kHQ}2jC9</UDF1>\x0D\x0A</FormData>\x0D\x0A'
local frm = FRM_IO.fromString(frmStr)
print(type(frm))
if frm then frm.show()end

ADDED:
add fromString with an optional loader so it may work for other filetype.
the saveForm function can be do with the designer ui bar menu/save.
oops, sry. I see my script is redundant after seeing the monohelper.lua @ git.
