Printing dollar from literals and variables
|
|
|
|
To survive the parser, a dollar sign must be doubled.
|
|
1 dollar literal => <single-quote-var-value>
|
|
1 dollar literal eol => <>
|
|
2 dollar literal => <$>
|
|
4 dollar literal => <$$>
|
|
Some hungry part of make eats all the dollars after a :U modifier.
|
|
1 dollar default => <>
|
|
2 dollar default => <>
|
|
4 dollar default => <>
|
|
This works as expected.
|
|
1 dollar variable => <>
|
|
2 dollar variable => <$>
|
|
4 dollar variable => <$$>
|
|
Some hungry part of make eats all the dollars after a :U modifier.
|
|
1 dollar var-default => <>
|
|
2 dollar var-default => <$>
|
|
4 dollar var-default => <$$>
|
|
|
|
Dollar in :S pattern
|
|
|
|
S,$,word, => <$XYword>
|
|
S,$X,word, => <$XY>
|
|
S,$$X,word, => <$XY>
|
|
S,$$$X,word, => <$XY>
|
|
S,$X,replaced, => <replaced>
|
|
S,$$X,replaced, => <replaced>
|
|
S,$$$X,replaced, => <replaced>
|
|
|
|
Dollar in :C character class
|
|
|
|
The A is replaced because the $$ is reduced to a single $,
|
|
which is then resolved to the variable X with the value VAR_X.
|
|
The effective character class becomes [VAR_XY].
|
|
C,[$$XY],<&>,g => <$<A><X><Y>>
|
|
|
|
Dollar in :C pattern
|
|
|
|
For some reason, multiple dollars are folded into one.
|
|
C,$,dollar,g => <>
|
|
C,$$,dollar,g => <>
|
|
|
|
Dollar in :S replacement
|
|
|
|
For some reason, multiple dollars are folded into one.
|
|
S,word,a$Xo, => <aVAR_Xo>
|
|
S,word,a$$Xo, => <aVAR_Xo>
|
|
S,word,a$$$Xo, => <aVAR_Xo>
|
