From 870f00bb36f5af3088344371764da48bbde9651a Mon Sep 17 00:00:00 2001 From: Christian Hesse Date: Thu, 3 Jan 2019 17:45:43 +0100 Subject: global: variable names are CamelCase ___ _ ___ __ / _ )(_)__ _ / _/__ _/ /_ / _ / / _ `/ / _/ _ `/ __/ /____/_/\_, / /_/ \_,_/\__/ _ __ /___/ _ __ | | / /___ __________ (_)___ ____ _/ / | | /| / / __ `/ ___/ __ \/ / __ \/ __ `/ / | |/ |/ / /_/ / / / / / / / / / / /_/ /_/ |__/|__/\__,_/_/ /_/ /_/_/_/ /_/\__, (_) /____/ RouterOS has some odd behavior when it comes to variable names. Let's have a look at the interfaces: [admin@MikroTik] > / interface print where name=en1 Flags: D - dynamic, X - disabled, R - running, S - slave # NAME TYPE ACTUAL-MTU L2MTU 0 RS en1 ether 1500 1598 That looks ok. Now we use a script: { :local interface "en1"; / interface print where name=$interface; } And the result... [admin@MikroTik] > { :local interface "en1"; {... / interface print where name=$interface; } Flags: D - dynamic, X - disabled, R - running, S - slave # NAME TYPE ACTUAL-MTU L2MTU 0 RS en1 ether 1500 1598 ... still looks ok. We make a little modification to the script: { :local name "en1"; / interface print where name=$name; } And the result: [admin@MikroTik] > { :local name "en1"; {... / interface print where name=$name; } Flags: D - dynamic, X - disabled, R - running, S - slave # NAME TYPE ACTUAL-MTU L2MTU 0 RS en1 ether 1500 1598 1 S en2 ether 1500 1598 2 S en3 ether 1500 1598 3 S en4 ether 1500 1598 4 S en5 ether 1500 1598 5 R br-local bridge 1500 1598 Ups! The filter has no effect! That happens whenever the variable name ($name) matches the property name (name=). And another modification: { :local type "en1"; / interface print where name=$type; } And the result: [admin@MikroTik] > { :local type "en1"; {... / interface print where name=$type; } Flags: D - dynamic, X - disabled, R - running, S - slave # NAME TYPE ACTUAL-MTU L2MTU Ups! Nothing? Even if the variable name ($type) matches whatever property name (type=) things go wrong. The answer from MikroTik support (in Ticket#2019010222000454): > This is how scripting works in RouterOS and we will not fix it. To get around this we use variable names in CamelCase. Let's hope Mikrotik never ever introduces property names in CamelCase... *fingers crossed* --- global-functions | 116 +++++++++++++++++++++++++++---------------------------- 1 file changed, 58 insertions(+), 58 deletions(-) (limited to 'global-functions') diff --git a/global-functions b/global-functions index 8b98507..8b7c5b3 100644 --- a/global-functions +++ b/global-functions @@ -5,12 +5,12 @@ # global functions # expected configuration version -:global ExpectedConfigVersion 1; +:global ExpectedConfigVersion 2; # global variables not to be changed by user -:global "sent-routeros-update-notification" "-"; -:global "sent-lte-firmware-upgrade-notification" "-"; -:global "identity" [ / system identity get name ]; +:global SentRouterosUpdateNotification "-"; +:global SentLteFirmwareUpgradeNotification "-"; +:global Identity [ / system identity get name ]; # read input from user :global Read do={ @@ -19,44 +19,44 @@ # url encoding :global UrlEncode do={ - :local input [ :tostr $1 ]; - :local return ""; + :local Input [ :tostr $1 ]; + :local Return ""; - :if ([ :len $input ] > 0) do={ - :local chars " %&"; - :local subs { "%20"; "%25"; "%26" }; + :if ([ :len $Input ] > 0) do={ + :local Chars " %&"; + :local Subs { "%20"; "%25"; "%26" }; - :for i from=0 to=([ :len $input ] - 1) do={ - :local char [ :pick $input $i ]; - :local replace [ :find $chars $char ]; + :for I from=0 to=([ :len $Input ] - 1) do={ + :local Char [ :pick $Input $I ]; + :local Replace [ :find $Chars $Char ]; - :if ([ :len $replace ] > 0) do={ - :set char ($subs->$replace); + :if ([ :len $Replace ] > 0) do={ + :set Char ($Subs->$Replace); } - :set return ($return . $char); + :set Return ($Return . $Char); } } - :return $return; + :return $Return; } # check and import required certificates :global CertificateAvailable do={ - :local commonname [ :tostr $1 ]; - :local filename ([ :tostr $2 ] .
