Macros: '^' , 'call' and 'set' Be a prelude to the wiki

[Mars]

Defined as:

{{set | A | B }}   and called by  {{^A}} or {{call | A }}

A is the name of the variable that you want to define
B is the text of replacement

{{set | rejetto | is the big boss }}       {{^rejetto}}  {{call | rejetto}}


*********************************************************

{{set | A | $1...  $2 .. $3  ...   /set}}   

A is the name of the variable that you want to define
$1,$2,..... are the parameters by defined order

{{set | rejetto | $1 $2  $3  $4 }}         {{^rejetto| is |the | big| boss}}   {{call | rejetto | is |the | big| boss}}


{{set | rejetto | $4 $3  $2  $1 }}         {{^rejetto| boss | big | the | is}}    {{call |rejetto| boss | big | the | is}}



*********************************************************

{{set | A | {{\ {{macroname | $1 | $2 | $3 | ...}}  /}} /set}}

A is the name the macro that you want to redefine
$1,$2,..... are the parameters by defined order

examples:


{{set | left | {{\ {{cut | 1 | $1 | $2}}  /}} }}    {{^left | 7 |Rejetto is the big boss}}
{{set | right | {{\ {{cut | -$1 | -1 | $2}}  /}} }}    {{^right | 4 |Rejetto is the big boss}}
{{set | mid | {{\ {{cut | $1 | $2 | $3}}  /}} }}    {{^mid | 8 |11 |Rejetto is the big boss}}


The call of the function or of the variable can be made by two manners:

{{^A | B | C | D |....}}
or
{{call | A | B | C | D |....}}

{{call | left | 7 |Rejetto is the big boss}}

*******************************************************

you can use A as a numeric value

{set | nb | 5 }}

{{^nb}}  = 5

{{inc | nb | 6 }}      {{^nb}}  = 11

-----------

{set | nb | 5 }}

{{dec | nb | 8 }}       {{^nb}}  = -3

{{inc | nb }}   and   {{dec | nb }}   They also work by step of 1

Good explanation. 

[rejetto]

by reading this explanation someone may think i'm an arrogant, while i'm just somewhat conceited.

inc will work with no parameters from next build.
dec is not planned. i guess {{inc|x| -5}} is enough.

|Rejetto is the big boss}}

by reading this explanation someone may think i'm an arrogant, while i'm just somewhat conceited.

It is just of the gratitude for all the work made with hfs

inc will work with no parameters from next build.
dec is not planned. i guess {{inc|x| -5}} is enough.

if inc will work with no parameter as {{inc|x}} then we must have {{dec|x}}

if (name ='inc') and (pars.count=1) then result:=p+1else result:=p+par(1)
if (name ='dec') and (pars.count=1) then result:=p-1 else result:=p-par(1)      juste une petite ligne en plus 

It is possible somewhere to have the necessity of writing

{{dec|x|{{^y}} }}  and nothing as  {{inc|x|  - {{^y}} }} 

forget - and result is not same as you like

[rejetto]

il n'est pas une ligne mais quatre
of course if you forget "-" the result is not the same, just as if you forget "^", you must always be careful, almost every character is important.

[Mars]

yes but if you forget ^

{{name}} return an error text, when name is not an implemented macro as CUT, ce qui est quand même plus facile à détecter dans le template  mais une erreur de signe ca ne pardonne pas, ça peut vous envoyer dans des boucles sans fin

i=10
x=2
while  i > 0 do begin
...
inc (i,-x)
end
