Sorry, I'm new to sbt and the "sbt-native-packager". What I need to do is to map whole directories to the .zip file and change the output path.
This how I've done my mapping of the directory:
mappings in Universal <++= (packageBin in Compile, baseDirectory ) map { (_, baseDirectory) =>
val dir = baseDirectory / "migrations"
(dir.***) pair relativeTo(dir.getParentFile)
}
The mapping works perfectly fine, but I need to have a specific folder structure in the resulting .zip file.
In this example this directory is mapped to ".../target/stage/universal/migrations" but I need it to be mapped into a folder "db" like this: ".../target/stage/db/universal/migrations"
Many thanks in advance!
For mapping complete directories there are some MappingHelpers you can use. Your code can be simplified to
mappings in Universal ++= directory(baseDirectory.value / "migrations")
Regarding your second question, how to change the output folder. The question is not quite correct, as it should be: "how to change the destination path of a mapping". The universal packaging is a bit special as the target ouput looks like the resulting package.
Native packager uses mappings (sequence of File -> String tuples) that define a file and the corresponding output path in the resulting package. So if you want to change
# current
./target/stage/universal/migrations
# expected
./target/stage/db/universal/migrations
I assume you want the migrations in your zip file in a db folder like this
/ # zip root
bin/ # start scripts
db/ # migrations go here
conf/ # configuration files
lib/ # jars
In order to accomplish this you have to change the destination string. This would look something like this ( not tested ):
mappings in Universal ++= contentOf(baseDirectory.value / "migrations").map {
case (file, dest) => file -> s"db/$dest"
}
cheers,

Following these instructions I have been able to copy files from their location and into the relative output directory.
.setOutputPath('public/assets/#BUILDNUMBER#')
.copyFiles({
from: './assets/images/favicon',
})
The docs go on to explain there is an optional "to" target path which I want to be "/images/favicon" (so the whole output path would be public/assets/#BUILDNUMBER#/images/favicon) but the way I'd expect to write this out creates errors when I run webpack.
.setOutputPath('public/assets/#BUILDNUMBER#')
.copyFiles({
from: './assets/images/favicon',
to: 'images/favicon'
})
Conflict: Multiple assets emit different content to the same filename images/favicon. Original source assets/images/favicon/ms-icon-150x150.png
I'll note that currently the auto-generated #BUILDNUMBER# directory has an images subdirectory but not a favicons subdirectory, I have also tried pointing to the already existing images directory instead but it produces this error:
Error: EISDIR: illegal operation on a directory, open '/opt/my-site/public/assets/#BUILDNUMBER#/images'
So how can I set my copyFiles "to" path to point to public/assets/#BUILDNUMBER#/images or public/assets/#BUILDNUMBER#/images/favicon?
I think you're missing the placeholders in the "to" parameter.
See the error message:
Conflict: Multiple assets emit different content to the same filename images/favicon
Webpack thinks "images/favicon" is the filename.
Maybe try this:
.copyFiles({
from: './assets/images/favicon',
to: 'images/favicon/[path][name].[ext]'
})
Here's a list of supported placeholders: https://github.com/webpack-contrib/file-loader#placeholders
If you're using versioning (.enableVersioning()) e.g. you have to add the hash as well:
.copyFiles({
from: './assets/images/favicon',
to: 'images/favicon/[path][name].[hash:8].[ext]'
})
Im new in qt. I use quazip for compress a folder and it compressed successfully.
But now if i want to know how many parents dir is available in unknown zip?
how can i get count of parent dir from zip file? before unzip.
please help me to get count of dir.
Is it possible by quazip? how?
QuaZip::getFileInfoList() should give you all the information needed. For the number of files just use the length of the returned list. Note that the file info is listed recursively. In case you need only the non-recursive content of a directory, go to that directory and iterate over all files with goToFirstFile() / goToNextFile().
I found the answer to my question:
Quazip zip("ZipFileName");
QuazipDir DirInZip(&zip);
int count = DirInZip.setFilter( QDir::Dir | QDir::NoDotAndDotDot|QDir::NoDot ).count();
The project root directory of a file located in PROJECT_ROOT/lib/code.jl can be accessed with this code:
root = dirname(dirname(#__FILE__))
Using dirname() twice seems pretty ugly. Is there a better way to do this? With Ruby, I would use this code:
root = File.expand_path('../', File.dirname(__FILE__))
Thanks for making me find out about:
"/"*relpath((#__FILE__)*"/../..","/")
According to ?relpath, it gives a path from the location of the second argument in the file-system, to the first argument. Is this better than the double dirname solution?
A variant of the same niceness is:
normpath(joinpath(#__FILE__,"..",".."))
Closest to Ruby equivalent might be:
realpath(dirname(#__FILE__)*"/..")
I like to use
module Foo
const PROJECT_ROOT = pkgdir(Foo)
end # module
where the definition of PROJECT_ROOT can also be replaced by
const PROJECT_ROOT = dirname(dirname(pathof(Foo)))
Or, you could use
const PROJECT_ROOT = pkdir(#__MODULE__)
I just use
const PROJECT_ROOT = #__DIR__
from inside my _init.jl file, which resides in the project root directory (next to the src directory) and gives you a canonical path.
I get my _init.jl files automatically executed when opening a Julia session from inside that directories by having
isfile("_init.jl") && include(joinpath(pwd(), "_init.jl"))
in my ~/.julia/config/startup.jl file. If you started Julia elsewhere, you have to include("_init.jl") it (or respective relative path) manually.
I have overridden the onProject function for the vs2012 action which generates some cpp files and then tries to include them in the project
--cant override the generateProject directly
--so have to override at the action level
premake.override( premake.action._list.vs2012, 'onProject', function(base, prj)
if premake.project.iscpp(prj) then
--generate files
--print( "Generating extra files ...")
local extraFiles = mine.getExtraFiles(prj)
for _,file in ipairs( extraFiles ) do
p.generate( file, nil, mine.generateExtraFile )
mine.addFileToSources(file)
end
end
--Generate regular stuff
base(prj)
end)
function mine.getExtraFiles(prj)
local extraFiles = {}
--works out what files to generate and add relevant info to table
return extraFiles
end
--this function is passed as a callback to premake.generate
function mine.generateExtraFile(extraFile)
--write contents of file
end
This is the function that attempts to add each generated file to the project
function mine.addFileToSources(extraFile)
local prj = extraFile.prj
local cfg = extraFile.cfg
local groups = premake.vstudio.vc2010.categorizeSources(prj)
local compiledFiles = groups.ClCompile or {}
--create a new file config for generated file
local filename = path.join(extraFile.location, extraFile.filename)
local fcfg = premake.fileconfig.new( filename, prj)
premake.fileconfig.addconfig(fcfg, cfg)
--add the config to the project's sources
table.insert(compiledFiles, fcfg)
compiledFiles[filename] = fcfg
--add to the projects source tree
--this bit is copied from premake.project.getsourcetree
-- The tree represents the logical source code tree to be displayed
-- in the IDE, not the physical organization of the file system. So
-- virtual paths are used when adding nodes.
-- If the project script specifies a virtual path for a file, disable
-- the logic that could trim out empty root nodes from that path. If
-- the script writer wants an empty root node they should get it.
local flags
if fcfg.vpath ~= fcfg.relpath then
flags = { trim = false }
end
-- Virtual paths can overlap, potentially putting files with the same
-- name in the same folder, even though they have different paths on
-- the underlying filesystem. The tree.add() call won't overwrite
-- existing nodes, so provide the extra logic here. Start by getting
-- the parent folder node, creating it if necessary.
local tr = premake.project.getsourcetree(prj)
local parent = premake.tree.add(tr, path.getdirectory(fcfg.vpath), flags)
local node = premake.tree.insert(parent, premake.tree.new(path.getname(fcfg.vpath)))
-- Pass through value fetches to the file configuration
setmetatable(node, { __index = fcfg })
end
For the most part - this all works:
The files are generated correctly and to correct location
The files are also included in the vcxproj file correctly
My problem is that the vcxproj.filters file is not being generated.
When I run premake I get this error:
Generating myproject.vcxproj.filters...Error: [string "src/actions/vstudio/vs2010_vcxproj_filters...."]:82: attempt to index field 'parent' (a nil value)
which corresponds to the function premake.vstudio.vc2010.filterGroup(prj, groups, group)
I get that the new fcfg I created needs to have a parent but I can't work out where or what I should be adding it to.
Can anyone help?
EDIT 1
I've got things working by adding this line to the end of function mine.addFileToSources(extraFile)
fcfg.parent = parent
This gives the file config a parent node so everything works out but I feel kinda dirty doing this so I'll look at following Citron's advice
EDIT 2
Overriding the bakefiles was much cleaner and neater. It wasn't as straightforward as Citron's code since I needed the information from the baked files in order to carry out my file generation but I am now confident that my code is correct and will possibly work with other exporters than vstudio too.
Here's my new code:
premake.override( premake.oven, 'bakeFiles', function(base, prj)
--bake the files as normal
local bakedFiles = base(prj)
if premake.project.iscpp(prj) then
--gather information about what files to generate and how
local extraFiles = mine.getExtraFiles(prj, bakedFiles)
for _,file in ipairs( extraFiles ) do
--do the generation
premake.generate( file, file.extension, mine.generateExtraFile )
--add the new files
local filename = premake.filename(file, file.extension)
table.insert(file.cfg.files, filename)
-- This should be the first time I've seen this file, start a new
-- file configuration for it. Track both by key for quick lookups
-- and indexed for ordered iteration.
assert( bakedFiles[filename] == nil )
local fcfg = premake.fileconfig.new(filename, file.prj)
bakedFiles[filename] = fcfg
table.insert(bakedFiles, fcfg)
premake.fileconfig.addconfig( bakedFiles[filename], file.cfg)
end
--sort the baked files again - since we have added to them
table.sort(bakedFiles, function(a,b)
return a.vpath < b.vpath
end)
end
return bakedFiles
end)
I don't know what the problem is with your code (a bit too much to read, and not enough time :p) but if you just want to add some generated files to your project tree, I would advise you to override premake.oven.bakeFiles instead.
This is what I used to add files generated by Qt in my addon. See premake.extensions.qt.customBakeFiles on https://github.com/dcourtois/premake-qt/blob/master/qt.lua
Basically in the bakeFiles override, you can just browse your projects, and insert files in the list easily. Then, if those added files need some custom configuration, you can then override premake.fileconfig.addconfig. See premake.extensions.qt.customAddFileConfig in the aforementioned addon.
In this addconfig override, you'll have access to the files and you will be able to modify their configuration object: you can add custom build rules, special options, etc.
It's not a direct answer to your specific question, but I hope it will help you achieve what you need.
We are moving into Scala/SBT from a Java/Gradle stack. Our gradle builds were leveraging a task called processResources and some Ant filter thing named ReplaceTokens to dynamically replace tokens in a checked-in .properties file without actually changing the .properties file (just changing the output). The gradle task looks like:
processResources {
def whoami = System.getProperty( 'user.name' );
def hostname = InetAddress.getLocalHost().getHostName()
def buildTimestamp = new Date().format('yyyy-MM-dd HH:mm:ss z')
filter ReplaceTokens, tokens: [
"buildsig.version" : project.version,
"buildsig.classifier" : project.classifier,
"buildsig.timestamp" : buildTimestamp,
"buildsig.user" : whoami,
"buildsig.system" : hostname,
"buildsig.tag" : buildTag
]
}
This task locates all the template files in the src/main/resources directory, performs the requisite substitutions and outputs the results at build/resources/main. In other words it transforms src/main/resources/buildsig.properties from...
buildsig.version=#buildsig.version#
buildsig.classifier=#buildsig.classifier#
buildsig.timestamp=#buildsig.timestamp#
buildsig.user=#buildsig.user#
buildsig.system=#buildsig.system#
buildsig.tag=#buildsig.tag#
...to build/resources/main/buildsig.properties...
buildsig.version=1.6.5
buildsig.classifier=RELEASE
buildsig.timestamp=2013-05-06 09:46:52 PDT
buildsig.user=jenkins
buildsig.system=bobk-mbp.local
buildsig.tag=dev
Which, ultimately, finds its way into the WAR file at WEB-INF/classes/buildsig.properties. This works like a champ to record build specific information in a Properties file which gets loaded from the classpath at runtime.
What do I do in SBT to get something like this done? I'm new to Scala / SBT so please forgive me if this seems a stupid question. At the end of the day what I need is a means of pulling some information from the environment on which I build and placing that information into a properties file that is classpath loadable at runtime. Any insights you can give to help me get this done are greatly appreciated.
The sbt-buildinfo is a good option. The README shows an example of how to define custom mappings and mappings that should run on each compile. In addition to the straightforward addition of normal settings like version shown there, you want a section like this:
buildInfoKeys ++= Seq[BuildInfoKey](
"hostname" -> java.net.InetAddress.getLocalHost().getHostName(),
"whoami" -> System.getProperty("user.name"),
BuildInfoKey.action("buildTimestamp") {
java.text.DateFormat.getDateTimeInstance.format(new java.util.Date())
}
)

sbt-editsource: An SBT plugin for editing files
sbt-editsource is a text substitution plugin for SBT 0.11.x and
greater. In a way, it’s a poor man’s sed(1), for SBT. It provides the
ability to apply line-by-line substitutions to a source text file,
producing an edited output file. It supports two kinds of edits:
Variable substitution, where ${var} is replaced by a value. sed-like
regular expression substitution.
