waf - update and generate translation pot file - translation

Is there a specific API call (maybe undocumented, none is listed here http://docs.waf.googlecode.com/git/apidocs_16/tools/intltool.html ) which allows me to create and/or update a translation template?
Or do I need use native system tools?

I could not find one either, so I introduced an option in my main wsript file.
opt.add_option('--update-po', action='store_true', default=False, dest='update_po', help='Update localization files')
// ...
def shutdown(self):
if Options.options.update_po:
os.chdir('./po')
try:
try:
size_old = os.stat (APPNAME + '.pot').st_size
except:
size_old = 0
subprocess.call (['intltool-update', '-p', '-g', APPNAME])
size_new = os.stat (APPNAME + '.pot').st_size
if size_new <> size_old:
Logs.info("Updated po template.")
try:
command = 'intltool-update -r -g %s' % APPNAME
self.exec_command (command)
Logs.info("Updated translations.")
except:
Logs.error("Failed to update translations.")
except:
traceback.print_exc(file=open("errlog.txt","a"))
Logs.error("Failed to generate po template.")
Logs.errors("Make sure intltool is installed.")
os.chdir ('..')
Unfortunately I haven't had the time to transform this into a tool yet. Is on my list. But you can find a full fledge sample here: https://bazaar.launchpad.net/~diodon-team/diodon/trunk/view/head:/wscript

How can I use the JAR tool with Bazel v0.19+?

Starting with Bazel v0.19, if you have Starlark (formerly known as "Skylark") code that references #bazel_tools//tools/jdk:jar, you see messages like this at build time:
WARNING: <trimmed-path>/external/bazel_tools/tools/jdk/BUILD:79:1: in alias rule #bazel_tools//tools/jdk:jar: target '#bazel_tools//tools/jdk:jar' depends on deprecated target '#local_jdk//:jar': Don't depend on targets in the JDK workspace; use #bazel_tools//tools/jdk:current_java_runtime instead (see https://github.com/bazelbuild/bazel/issues/5594)
I think I could make things work with #bazel_tools//tools/jdk:current_java_runtime if I wanted access to the java command, but I'm not sure what I'd need to do to get the jar tool to work. The contents of the linked GitHub issue didn't seem to address this particular problem.
I stumbled across a commit to Bazel that makes a similar adjustment to the Starlark java rules. It uses the following pattern: (I've edited the code somewhat)
# in the rule attrs:
"_jdk": attr.label(
default = Label("//tools/jdk:current_java_runtime"),
providers = [java_common.JavaRuntimeInfo],
),
# then in the rule implementation:
java_runtime = ctx.attr._jdk[java_common.JavaRuntimeInfo]
jar_path = "%s/bin/jar" % java_runtime.java_home
ctx.action(
inputs = ctx.files._jdk + other inputs,
outputs = [deploy_jar],
command = "%s cmf %s" % (jar_path, input_files),
)
Additionally, java is available at str(java_runtime.java_executable_exec_path) and javac at "%s/bin/javac" % java_runtime.java_home.
See also, a pull request with a simpler example.
Because my reference to the jar tool is inside a genrule within top-level macro, rather than a rule, I was unable to use the approach from Rodrigo's answer. I instead explicitly referenced the current_java_runtime toolchain and was then able to use the JAVABASE make variable as the base path for the jar tool.
native.genrule(
name = genjar_rule,
srcs = [<rules that create files being jar'd>],
cmd = "some_script.sh $(JAVABASE)/bin/jar $# $(SRCS)",
tools = ["some_script.sh", "#bazel_tools//tools/jdk:current_java_runtime"],
toolchains = ["#bazel_tools//tools/jdk:current_java_runtime"],
outs = [<some outputs>]
)

How to invoke CROSSTOOL tools from Bazel macros / rules?

I'm building ARM Cortex-M firmware from Bazel with a custom CROSSTOOL. I'm successfully building elf files and manually objcopying them to binary files with the usual:
path/to/my/objcopy -o binary hello.elf hello.bin
I want to make a Bazel macro or rule called cc_firmware that:
Adds the -Wl,-Map=hello.map flags to generate a mapfile
Changes the output elf name from hello to hello.elf
Invokes path/to/my/objcopy to convert the elf to a bin.
I don't know how to get the name of a CROSSTOOL tool (objcopy) to invoke it, and it feels wrong to have the rule know the path to the tool executable.
Is there a way to use the objcopy that I've already told Bazel about in my CROSSTOOL file?
You can actually access this from a custom rule. Basically you need to tell Bazel that you want access to the cpp configuration information (fragments = ["cpp"]) and then access its path via ctx.fragments.cpp.objcopy_executable, e.g.,:
def _impl(ctx):
print("path: {}".format(ctx.fragments.cpp.objcopy_executable))
# TODO: actually do something with the path...
cc_firmware = rule(
implementation = _impl,
fragments = ["cpp"],
attrs = {
"src" : attr.label(allow_single_file = True),
"map" : attr.label(allow_single_file = True),
},
outputs = {"elf" : "%{name}.elf"}
)
Then create the output you want with something like (untested):
def _impl(ctx):
src = ctx.attr.src.files.to_list()[0]
m = ctx.attr.map.files.to_list()[0]
ctx.action(
command = "{objcopy} -Wl,-Map={map} -o binary {elf_out} {cc_bin}".format(
objcopy=ctx.fragments.cpp.objcopy_executable,
map=m,
elf_out=ctx.outputs.elf.path,
cc_bin=src,
),
outputs = [ctx.outputs.elf],
inputs = [src, m],
)

Mixing Ruby and bash commands -- mv returns "x and y are the same file"

So I have a Ruby script (using Ruby because we have a library of pre-existing code that I need to use). From within Ruby I am using backticks to call Linux commands, specifically in this case the "mv" command. I am trying to move one file to another location but I keep getting the error message that x and y are "the same file" even though they are very clearly NOT the same file.
Here is the code in Ruby:
#!/usr/local/rvm/rubies/ruby-2.1.1/bin/ruby
masterFiles=[]
masterFiles << "/mnt/datadrive/Data Capture/QualityControl/UH_HRA_SVY/Scans and DataOutput/Data/UH_HRA_SVY_DATA.txt"
masterFiles << "/mnt/datadrive/Data Capture/QualityControl/UH_HRA_SVY_SPAN/Scans and DataOutput/Data/UH_HRA_SVY_SPAN_DATA.txt"
tm=Time.new.strftime("%Y%m%d")
masterFiles.each do |mf|
if File.exist?(mf)
qmf=39.chr + mf + 39.chr
`cat #{qmf} >> /tmp/QM`
savename=39.chr + \
"/mnt/datadrive/Data Capture/QualityControl/UH_HRA_SVY/Scans and DataOutput/Data/DailyFiles/" + \
File.basename(mf).gsub(".txt","_"+tm) + ".txt" + 39.chr
`mv #{qmf} #{savename}`
end
end
The error that I get is this:
mv: `/mnt/datadrive/Data Capture/QualityControl/UH_HRA_SVY_SPAN/Scans
and DataOutput/Data/UH_HRA_SVY_SPAN_DATA.txt' and `/mnt/datadrive/Data
Capture/QualityControl/UH_HRA_SVY/Scans and
DataOutput/Data/DailyFiles/UH_HRA_SVY_SPAN_DATA_20140530.txt' are the
same file
If I change this line:
`mv #{qmf} #{savename}`
To this:
puts "mv #{qmf} #{savename}"
And then run the output, it works as expected.
I am pretty sure that this has to do with spaces in the path. I have tried every combination of double-quoting, triple-quoting, quadruple-quoting, and back-slashing I can think of to resolve this but no go. I have also tried using FileUtils.mv but get what is basically the same error worded differently.
Can anybody help ? Thanks a lot.
p.s. I realize it's entirely possible that I could be going about this in an entirely wrong-headed way, so feel free to point that out if so. However, I am trying to use the tools which I already have some knowledge of (cat, mv, etc) instead of re-inventing the wheel.
You could use FileUtils.mv
I often do aliases like so:
require 'fileutils'
def mv(from, to)
FileUtils.mv(from, to)
end
And inside the mv() method I do additional safeguards, i.e. if the file does not exist, if there is a lack of permissions and so forth.
If you then still have problems with filenames that have ' ' blank characters, try to put the file into a "" quote like:
your_target_location = "foo/bar bla"

Sublime text build system - how to auto open pdfs

I followed instructions provided here(How to create a shortcut for user's build system in Sublime Text?) to compile latex documents in xelatex, and on top of that I would also like it to automatically open pdf after compiling just like with latexmk, how can I achieve that? The document is built just fine, but I have to open it each time manually.
Here's an extension to the CompileWithXelatexCommand implementation that successfully opens the PDF in my default PDF viewer.
import sublime, sublime_plugin
import os
import time
class CompileWithXelatexCommand(sublime_plugin.TextCommand):
def run(self, edit):
if '/usr/texbin' not in os.environ['PATH']:
os.environ['PATH'] += ':/usr/texbin'
base_fname = self.view.file_name()[:-4]
pdf_fname = base_fname + ".pdf"
self.view.window().run_command('exec',{'cmd': ['xelatex','-synctex=1','-interaction=nonstopmode',base_fname]})
tries = 5
seconds_to_wait = 1
while tries > 0:
if os.path.isfile(pdf_fname):
break
time.sleep(seconds_to_wait)
seconds_to_wait *= 2
tries -= 1
os.system("open " + pdf_fname)
The polling loop is required; otherwise, the open call may happen before the PDF has been generated. There may be a cleaner way to synchronously exec a sequence of commands via run_command.
I don't have access to Windows now, but from this post you'll probably just need to change "open " to "start ". The PATH initialization logic will either need to be eliminated or adjusted.

Iexpress - extraction path

I am going to create a self extracting archive but I have got a problem connecting with the default path of the extraction. I would like to extract my files in the same path as the self-extraction archive program. Unfortunately, the files are extracting in another path (C:\Users\computer\AppData\Temp\IXP000.TMP). Is it possible to set the path?
I can't find any direct way to do this with IExpress, but there is a trick we can apply.
But first I'll point out that this is really easy with something like 7-Zip's 7zCon.sfx module (if all you need to do is have the archive extract to the current directory, no questions asked). So you might just want to try something other than IExpress.
Anyhow, the problem with IExpress is that, at the time our install program runs, we're no longer in the directory of the original archive; the current directory is now something like %temp%\IXP000.TMP. So we need to find the directory of our parent process – kind of a pain. Once that's known, we can just xcopy the contents of the archive over to the destination folder.
In VBScript, it would look something like this:
Option Explicit
Dim objShell, objWMI
Dim objCmd, intMyPid, intMyParentPid, objMyParent
Set objShell = CreateObject("WScript.Shell")
Set objWMI = GetObject("winmgmts:root\cimv2")
Set objCmd = objShell.Exec("cmd.exe")
intMyPid = objWMI.Get("Win32_Process.Handle='" & objCmd.ProcessID & "'").ParentProcessId
objCmd.Terminate
intMyParentPid = objWMI.Get("Win32_Process.Handle='" & intMyPid & "'").ParentProcessId
Set objMyParent = objWMI.Get("Win32_Process.Handle='" & intMyParentPid & "'")
objShell.Run "xcopy /y * " & """" & Left(objMyParent.ExecutablePath, _
InStrRev(objMyParent.ExecutablePath, ".exe", -1, vbTextCompare) -1) &_
"\""", 0, True
Your install program would then be, eg: wscript extractToOriginalLocation.vbs //B.
(Inspired somewhat by the answer to this question.)
You could always use a cmd script and echo lines of code into files in specific directories
