c++ and python stuf

[bluatigro]

idea's from c++ :



#ifndef somemodule_h
#define somemodule_h

''so this code wil be imported once

#endif

''this is useful too

#replace a<b<c ((a)<(b))and((b)<(c))

''i don't know if i need this

#macro  somemarco
''some code
#endmacro

all # has to have a different color than othercode

from python

''list's 
list# = [ 1 , 2 , 3 , 4 , 5 ]
list# = list( 1 , 2 , 3 , 4 )
list# = list#[ 1 : 3 , -1 ]a = len( list# )q# = a# + b#
''dictonary's
dict% = dict()
dict% = { "a" ; 1 , "b" , 2 }
dict%[ "a" ] = 5a = len( dict% )q% = a% + b%
''tuple's
tuple@ = tuple( 1 , )
tuple@ = ( 1 , )a = len( tuple@ )''tuple's are inmuteble so q@ = a@ + b@ is not good''string'spart$ = a$[ -5 , -2 ] 
''list dict and tuple same color as reseved word's
''@carl : the symvol's may be different but you get the point

basic extentions

''other color than other code for
( ) , + - * / ^ [ ] { } ;
''binary number's same color as other numbers
%1111000
''hex number's same color as other numbers
h&ffffff
''path incusion for ordering my module's
import "modules\openGL\bluaGL.bas"
''import same color as reserved word's
''true false and pi as fixed and color as reseved word's
const q = 13
const q$ = "hello"
''const list's dict's and tuple's too
''if you chage a const you have to get a error

i have in freebasic the folowing color's setting's in my ide :

remark's black on green bold

#stuf black on pink bold

symbol's black on yellow bold

reseved word's black on cyan bold

number's red on white normal [ also hex ]

string's literal's green on white normal

variable's and array's black on white normal

function's and sub name's black on white normal

selection white on blue normal

error white on red bold

background white

i want the same in LB5 or that i can fix this in the ide myself

even better :

al in 1 line independently fixeble

bineary literal same as number

list's , dictoinary's and tuple's literal's same as string's

i need a null / nothing / none item too

Customizable syntax colors are important to me also, so I will try to put them into LB5.

[Carl Gundel]

I will certainly consider features from other languages, but I tend to shy away from alien language features because I don't want LB to begin to look really weird.

[bluatigro]

@carl :

coding a language is a lot of work so i understand

and i have some idea what you can do whit LB5 if you put it all in

the code wil get verry strange indeed

but verry powerful

do at least :

#include "modules\openGL\blueGL.bas"
swap a , b
swap a(1) , a(2)
swap a$ , b$
swap a$( 1 ) , a$( 2 )
''byref on array's
a = -a
a = sng( a )  ''return's :  1 for > 0 , 0 for = 0 and -1 for < 0
''these things i realy missing



[Chris Iverson]

If I could have a wish for one feature from Python, it would be the ease of which it handles arrays/lists(including how strings are automatically considered to be arrays of characters when useful). Particularly, array slicing.

Need to strip out the first, second, and last items of the array?

newArray = oldArray[2:-1]

Done. (This came in handy when I wrote the code for scraping the conforums.)

Need to reverse a string?

myStr = "whee"
revStr = myStr[::-1]
#revStr is now "eehw"


Formatting a number with a forced number of prefixed zeros for a standard length?

num = 12
formatNum = ("0000" + str(num))[-4:]
#formatNum is now "0012"

Chris,

Very useful, I agree. But ugly, from a BASIC sense of style.

[Chris Iverson]

Ah, true, that's a good point. Hmm.

Oh, well. Honestly, as long as we get expanded ability to work with arrays/structs as a first-class type(something which I believe has already been shown in previous LB5 alpha builds, although it's been a LONG time since I've played with one of them), I'll be happy. This would just be icing on the cake.

[Sver]

More usefull : Something like GETGPS or to get other sensor information, when you use a windows tablet.
That 'll make LB more attractive for lot of people.

Or example's

[bluatigro]

@ chris

it can already be done whit strings


a$ = "abcdefghijklmnopqrstuvwxyz"
print "a$ = " ; a$
print "newstr$( a$ , 5 , 15 , 1 ) = " ; newstr$( a$ , 5 , 15 , 1 )
print "newstr$( a$ , 5 , 15 , -1 ) = " ; newstr$( a$ , 5 , 15 , -1 )
print "newstr$( a$ , 5 , -5 , 1 ) = " ; newstr$( a$ , 5 , -5 , 1 )
print "newstr$( a$ , 5 , -5 , -1 ) = " ; newstr$( a$ , 5 , -5 , -1 )

end
function newstr$( in$ , a , b , c )
 if a < 0 then
   a = a + len( in$ ) + 1
 end if
 if b < 0 then
   b = b + len( in$ ) + 1
 end if
 if c > 0 then
   for i = a to b step c
     uit$ = uit$ + mid$( in$ , i , 1 )
   next i
 end if
 if c < 0 then
   for i = b to a step c
     uit$ = uit$ + mid$( in$ , i , 1 )
   next i
 end if
 newstr$ = uit$
end function
