just another time, for baddly format :(
okay, i used Vim for years, and I really really love her. i'm a
script-writer, so i want to create everything with vim-script, it's
wonderful, i know, but need improved. i think add these feature are
very simple(i will give the reason), and these can make a revolution
to script-writer!! it's worth to read it, i swear. just take you
several minutes.
1. interaction with other application
yes, the first big problem!! Vim has Unix-traditional isn't it? so
it should have the philosophy Unix have: just mix tools for you,
not a stiffness program. now Vim CAN interaction with other
program, yes, through perl, python, ruby, tcl, netbeans, etc. i
know. but i haven't study either of above, let's face the
readlity: why not afford a interface in the Vim-script? it not
hard, because we always have cscope-connect() function. just add
some bulit-in function below:
executable({expr})
yes! we just have this function yet!!
isconnect({expr})
return whether a program has connected to program. it can
replace cscope_connect. if expr is a number, it's the pid
of program, and if it's a string, it's the name of
program.
connect({expr})
connect Vim and a program, that is, Vim run it, and if it
wait for input, let it wait, untill kill it or give it
input it want. this function return the pid of program
returned. expr use for string, it's the name of program to
run, program must be in $PATH.
kill({expr}[,{sid}])
to kill a connected program has pid or name of {expr}
(just like the {expr} parameter of isconnect() ), and if
has {sid}, just send a signal {sid} to program.
sendto({expr}, {data}[,{varname}])
the most important function!! send data to the connected
to the program of {expr} (just like the {epxr} parameter
of isconnect()).
treat data as string, and if expr is a list, treat this
list a multi-line text(just like setline() ).
if doesn't give varname, this is a synchronization
operation, function will wait till the connect-program
sendback the response, and the return value is the
response, string. but if set the varname, the operation is
async, the result will save in a variable named varname,
if responsed.
if has any error, put error-code to v:connect_error (just
like v:shell_error), and return empty (if it's a async,
set variable named varname to empty, too)
just five function (one of it has implement yet), Vim-script can
interaction with other program. it's easy, isn't it? and if do so,
we can apart cscope and grep from Vim, just use plugin to
implement them.
a new idea, we can set system function to:
system({expr}[, {input}[, {varname}]])
and make it can support sync and async operation. but is it hard
to implement?
2. more powerful autocmds
Timer Support:
first we can add timer support. just two command, settimer and
killtimer. it can raise Timer autocmd, e.g. :settimer 1s, 1
will set a timer, that raise Timer autocmd per 1 second, and
the Timer id is 1, and :killtimer 1 will kill the timer. may
be have several functions:
hastimer({expr})
expr use to id, and return whether the timer exists.
alloctimer(),
return a free id for new timer.
this will be very useful, it can detect whether the operation
takes a long time, and can used in game, it's a
paltform-specified, so add it as a timer will be good, and if
it slow, just can add a option 'enabletimer' 'ent' to
disable/enable it.
buffer-modified detect:
maybe can add a autocmd BufModfied, <aopera> is the operation,
'a' add, 'd' delete, 'm', modified, etc, and <amatch> is the
text of modified (or other ways, all in all, just afford a way
to detect wthether the buffer changed), it useful to make
on-the-fly plugin, and if choose a right way to implement, it
may be very simple. and maybe another autocmd BufModfiedI,
raised in modified operation in insert mode. it's very simple,
but it's powerful. (e.g. can add BufTextAdd, BufTextDelete,
etc, this is another way to implement, I don't know which one
is more effitive)
thanks for reading, I'm a programer, I think to add these feature
isn't very hard, but they are useful, isn't it? I'm in my third years
in collenge, my mayjor is compuer science. so if nobody want to
implement it, i want to try, just hope anyone can support me!
