回复： "${xxx}" problem in env.Textfile source string

Hello Daniel Moody,
When I just wanted to confirm this problem again, I found that it was inconsistent with the test results yesterday. There is no problem now, I don't know what caused it yesterday, but it can be ignored for now. Thanks!

主题:&nbsp;Re: [Scons-users] "${xxx}" problem in env.Textfile source string



double dollar sign worked for me, this was my test:

env = Environment(tools=['textfile'])
env.Textfile('out.txt',
&nbsp; &nbsp; '$${workspaceRoot}\\myPath'
)

out.txt:
${workspaceRoot}\myPath

 shouldn't be.... the doubled $$ should turn off interpretation of the
 variable reference, whether it's wrapped in {} or not.&nbsp; &nbsp;Sometimes there
 are so many layers of substitution that things are more complex... we'll
 see if anyone else has ideas.
