problem with =~
|
#alias test_bug
#IF ("%1" =~ "foobar") {#SHOW true foobar = "%1"}
#IF ("%1" =~ "true foobar") {#SHOW true true foobar = "%1"}
#IF ("%1" =~ "false foobar") {#SHOW true false foobar = "%1"}
when run with: test_bug "true foobar"
The output is this, can anyone explain why?
true foobar = true foobar
true true foobar = true foobar
true false foobar = true foobar
From the Help text "v1 =~ v2 true if the string v1 matches the pattern in v2
"
Clearly in the example above v1="false foo bar" should not match with v2="true foobar" |

also this seems wrong too but using an exact match
alias test_bug
#SHOW %1
#IF ("%1" = "monster") {#SHOW buggy} {#SHOW correct}
#IF ("%1" = "a") {#SHOW buggy} {#SHOW correct}
run with test_bug "a monster"
Output is
a monster
buggy
buggy
Again how can "a monster" be equal to "a" and "monster".
this is even more bazar
call with test_bug "a fred"
get the output
a fred
buggy
buggy
not sure how "fred" = "monster" |

use "%-1" in place of "%1" while testing a couple of words
#IF ("%-1" =~ "true foobar") {#SHOW true true foobar = "%-1"}
and test without quotation marks:
test_bug true foobar |

Also you should understand that quotes and braces are included in the arguments of alias.
#AL Example {#ECHO %char(%ascii("%1"))}
Example "a"
returns: "
Example {a}
returns: {
If you remove the quotes in the alias then the parser will strip whatever delimeter was used when calling the alias.
#AL Example {#ECHO %char(%ascii(%1))}
Example "a"
returns: a
Example {a}
returns: a |
