Nate Chadwick commented on VELOCITY-542: ---------------------------------------- Here is an example that is close to solving the $variable-1 issue that [~spbolton] has been hacking on: {code} <#ALPHA_CHAR: ["a"-"z", "A"-"Z", "_" ] > | <#ALPHA_NUM_CHAR: [ "a"-"z", "A"-"Z", "_" "0"-"9" ] > | <#IDENTIFIER_CHAR: [ "a"-"z", "A"-"Z", "0"-"9", "_" ] > | <#IDENTIFIER_DASH: [ "-" ] > | <#IDENTIFIER_CHAR: [ "a"-"z", "A"-"Z", "0"-"9", "-", "_" ] > | <IDENTIFIER: ( <ALPHA_CHAR> ) ((<IDENTIFIER_DASH> <ALPHA_CHAR>) | (<ALPHA_NUM_CHAR>))*) >`` {code} One of the problems with this approach that still needs addressed is handling something like: {code} $velo-Var--897 {code} Which may be handleable by making -- an Operator that equates to + (had to remember 5th grade math for that!). Would really appreciate a re-open so that we can solve this in a way that you have 1 parser and don't need to eliminate - as a valid character in language identifiers. I don't have permissions to reopen a closed bug. The correct fix just needs more work and testing. > minus sign in #set requires spaces to surround it > ------------------------------------------------- > > Key: VELOCITY-542 > URL: https://issues.apache.org/jira/browse/VELOCITY-542 > Project: Velocity > Issue Type: Bug > Components: Engine > Affects Versions: 1.5 > Reporter: Will Glass-Husain > Assignee: Claude Brisson > Priority: Minor > Fix For: 2.0 > > > The following example: > #set($thisCampNumber = 10) > #set($nextCampNumber = $thisCampNumber+1) > #set($previousCampNumber = $thisCampNumber-1) > #set($previousCampNumberB = $thisCampNumber - 1) > 1: $thisCampNumber<br> > 2: $nextCampNumber<br> > 3: $previousCampNumber<br> > 4: $previousCampNumberB<br> > produces this result > 1: 10 > 2: 11 > 3: $previousCampNumber > 4: 9 > Note that using a minus sign in a #set statement does not work if there are > no spaces around it. (however, the same is not true for +). -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@velocity.apache.org For additional commands, e-mail: dev-h...@velocity.apache.org
