Nice Job!
When looking through this, I thought of a way to implement console based applications. Instead of using pattern matching on the associations table build, use the colon as a delimiter, by doing this we could eliminate the need of the grun consfile and its implementation. Simply by specifying, as we do for fluxbox menu, via an aterm -e prefix. For example, in my assoc file I added the following lines:
lua:aterm -e vi
lst:aterm -e vi
sh:aterm -e vi
To implement this meant only to change the table build from pattern matching to delimiter. Here is the modded flrun.lua
| Code Sample |
#!/bin/lua
-- Launches applications under X
-- by Daniel Plata Lorenzo "MakodFilu"
version="1.0.0"
max_history=10
history_file=os.getenv("HOME").."/.flrun_history"
gassoc_file="/opt/grun/gassoc"
ww=250 --window width
wh=100 --window height
bw=60 --button width
bh=25 --button height
-- L10N (Somewhat)
window_text="flRun v"..version -- Try FireSomething for the fun of it
input_text="Launch Application"
cancel_text="&Cancel"
cancel_tooltip="Cancel launch"
ok_text="&Ok"
ok_tooltip="Launch application"
browse_text="&Browse"
browse_tooltip="Browse for command"
choose_text="Choose Application"
-- Code
w=fltk:Fl_Window(ww,wh,window_text)
history_table={}
table_length=0
file = io.open(history_file, "r")
if file then
for line in file:lines() do
table.insert(history_table, line)
end
file:close()
table_length=table.maxn(history_table)
if not table_length then table_length=0 end
end
assoc = {}
file = io.open(gassoc_file, "r")
if file then
for line in file:lines() do
i,_ = string.find(line,":")
if i then
local j = #assoc+1
assoc[j] = {}
assoc[j][1] = string.sub(line,1,i-1)
assoc[j][2] = string.sub(line,i+1)
end
end
end
input = fltk:Fl_Input_Choice(10,30,ww-20,bh,input_text)
input:align(fltk.FL_ALIGN_TOP)
if table_length~=0 then
input:value(history_table[table_length]) -- Show last feed command
for i=1,table_length,1 do
input:add(history_table[i])
end
end
ok = fltk:Fl_Return_Button(ww-3*bw*1.2,wh-35,bw,bh,ok_text)
ok:tooltip(ok_tooltip)
ok:callback(
function(ok)
if input:value() == "" then
io.write(string.char(7)) io.flush()
else
if table_length < max_history then start=1
else start=table_length-(max_history-2) -- Discard older entries
end
io.output(io.open(history_file,"w+"))
for i=start,table_length,1 do
if history_table[i]~=input:value() then
io.write(history_table[i]..'\n')
end
end
io.write(input:value()..'\n')
io.close()
command=input:value()
if command:find("%.%a*$") then
ext=command:sub(command:find("%.%a*$"))
for i=1,#assoc,1 do
if ext == '.'..assoc[i][1] then
command=assoc[i][2]..' '..command
end
end
end
os.execute(command..' 2>/dev/null &')
os.exit(0)
end
end)
cancel = fltk:Fl_Button(ww-2*bw*1.2,wh-35,bw,bh,cancel_text)
cancel:tooltip(cancel_tooltip)
cancel:callback(
function(cancel)
os.exit(0)
end)
browse = fltk:Fl_Button(ww-1*bw*1.2,wh-35,bw,bh,browse_text)
browse:tooltip(browse_tooltip)
browse:callback(
function(browse)
input:value(fltk.fl_file_chooser(choose_text,"*",single,nil))
end)
if not arg[1] then
w:show()
Fl:run()
else
print ("flRun v"..version.." launches applications under X\n")
print "Usage flrun\n" -- [options] [file options]\n"
-- print " file options Launch file directly, no dialog boxes"
-- print " --persist Dialog persistance"
-- print " --preload file Load file as default command"
-- print " --notips Disable tooltips"
