Translating lisp -- Please help!!!

Hi,

I neeed to translate about 150 autolisp routines. Basically, I have to
prefix the commands with "._" and the command options with "_", as shown
below:

(command "pline" "0,0" "w" "3" "" "10,10" "")

(command "._pline" "0,0" "_w" "3" "" "10,10" "")

My (big) problem is that the command could have parentesis inside like that:

(command "pline" (calculate_start_point) ...)

and I have to distigue between options and inputs (like "w" and "3").

Actually I'm trying to write a parser, but I think it is very complex...

Is there a way to do this automatically?

Please help me!!!!

Thanks,

Andre

 

If they are not very long routines, consider loading all into the same
editor (I use TextPad) as a single file with separators at each start so
they can easily be broken out later.

Most editors support "regular expressions" for complex search and
replace operations. Unless you happen to be experienced at REs (and I am
not) stay away from them; you can do unimaginable damage with a single
keystroke.

I would start at the top of the combined file and read until I found a
command that needed to be changed. Then I would Find and Replace that
command throughout the file. Editors make that part easy. I would
continue doing that until the entire file was processed. I know that
sounds like a lot of drudgery but you will find that the most common
commands will be taken care of quickly and you will find fewer and fewer
as you progress.

Perhaps there is a program to do what you need. However, writing a
program for yourself will prove more time-consuming than the suggested
procedure.

why not just changing in text editor each occurence of the string (command " with the string (command "._ ? it should do what you need for all commands.
For command options I think it should only be executed as many times as many characters the ABC has, since options begin always with such characters not numbers. By changing each "a to "_a up to each "z to "_z should solve the problem.
This all could also be written into a very simple ms-basic routine or even acad-batch file to ease the whole stuff.

 

If that's all he needs, it's almost great. You have to account for commands that
already have ._ so they don't double. Two strikes: 1) Replace [(command "._]
with [Command "]. 2) Like you said. Unless there are some with ". and others
with "_ etc. Then either go through 2 more times or Regular Expressions.
