I have a problem which I can't seem to understand. I'm using TortoiseHg (version 0.7.5) on Windows but on Linux I have the same problem. Here it is:
My .hgignore file:
syntax: regexp
^[^\\/]+$
What I'm trying to achieve is to add to the ignore list the files which are in the root of the hg repository.
For example if I have like this:
.hg
+mydir1
+mydir2
-myfile1
-myfile2
-anotherfile1
-anotherfile2
.hgignore
I want myfile1(2) and anotherfile1(2) to be ignored (names are only for the purpose of this example - they don't have a simple rule that can be put in the hgignore file easily)
Is there something I'm missing because I'm pretty sure that regexp is good (I even tested it)? Ideas?
Is there a simpler way to achieve this? [to add to the ignore list files that are in the root of the mercurial repository]
I relayed this question in #mercurial on irc.freenode.net and the response was that you cannot distinguish between files and directories — the directory is matched without the slash that you're searching for in your regexp.
However, if you can assume that your directories will never contain a full-stop ., but your files will, then something like this seems to work:
^[^/]*\..*$
I tested it in a repository like this:
% hg status -ui
? a.txt
? bbb
? foo/x.txt
? foo/yyy
Adding the .hgignore file gives:
% hg status -ui
? bbb
? foo/x.txt
? foo/yyy
I .hgignore
I a.txt
which indicates that the a.txt file is correctly ignored in your root directory, but x.txt in the foo subdirectory is not. You can also see that a file named just bbb in the root directory is not ignored. But maybe you can add such files yourself to the .hgignore file.
If you happen to have a directory like bar.baz in your root directory, then this directory and all files within will be ignored. I hope this helps a bit.
Here is a dirty trick:
Create an empty file ".hidden" in your directory, than add to .hgignore:
^mydir/(?!\.hidden).+$
This will ignore all files in the directory except ".hidden".

I am using cpplint to check my sourcode agains the google style guide.
Cpplint's help says:
cpplint.py supports per-directory configurations specified in CPPLINT.cfg
files. CPPLINT.cfg file can contain a number of key=value pairs.
Currently the following options are supported:
"exclude_files" allows to specify a regular expression to be matched against
a file name. If the expression matches, the file is skipped and not run
through liner.
Example file:
filter=-build/include_order,+build/include_alpha
exclude_files=.*\.cc
The above example disables build/include_order warning and enables
build/include_alpha as well as excludes all .cc from being
processed by linter, in the current directory (where the .cfg
file is located) and all sub-directories.
How I use cpplint:
I use cpplint by this command to check all files in my source folder:
cpplint src/*.c
Well there is one special file foo.cc which must not be checked. So I tried to create a CPPLIN.cfg to use the exclude_files property. My file looks like this:
set noparent
filter=-build/include_dir
exclude_files=foo.cc
Nevertheless foo.cc is still checked.
What I have already tried to do:
I tried exclude_files=/.*\.cc/. This should exclude all files ending with *.cc. Nevertheless all files are still checked.
I tried to remove my filter from the file. This caused more errors than before. So I am now sure that my CPPLINT.cfg file is found by cpplint.
Question:
How to use the exclude_files regex in cpplint correctly?
Turns out apparently that the doc is wrong: exclude_files only excludes files in the same directory as CPPLINT.cfg, not in subdirectories. See https://github.com/google/styleguide/issues/220
So the solution would be to create src/CPPLINT.cfg and put exclude_files=.*\.cc in it.
Using .gitignore, is there a way to ignore a directory if it contains a certain file (or directory)?
This would be something like look-ahead assertions, though my use case is a little different: I want to ignore Mercurial repos in my project, to keep from accidentally committing them as part of the project. That is, I want to ignore all directories containing .hg, not just .hg itself.
I can work around this using the answer from this question, adding each directory name to .gitignore, but I'd like to make it more general if I can.
There is no way to do it beside adding all of them to your .gitignore file.
What you can do it to write a scipt which append all the desired paths to your .gitignore.
The content of .gitignore is alist of paths so git can be configured based upon content.
Each line in a gitignore file specifies a pattern
I'm using ag to search a git repo. It doesn't find matches under my node_modules subdirectory. Why not, and how can I control this behavior?
It turns out that ag honors the contents of the .gitignore file by default. So if node_modules is in .gitignore, ag won't search it. This is all sensible behavior, but difficult to debug if you aren't expecting it. Hopefully this post will help.
There's a good summary at the end of man ag:
IGNORING FILES
By default, ag will ignore files whose names match patterns in .gitig-
nore, .hgignore, or .agignore. These files can be anywhere in the
directories being searched. Ag also ignores files matched by the
svn:ignore property if svn --version is 1.6 or older. Finally, ag looks
in $HOME/.agignore for ignore patterns. Binary files are ignored by
default as well.
If you want to ignore .gitignore, .hgignore, and svn:ignore, but still
take .agignore into account, use -U.
Use the -t option to search all text files; -a to search all files; and
-u to search all, including hidden files.
For my purposes ag -t seems to work well.
I would like to use the .hgignore file of Mercurial to ignore all files with file extension .tex, except those .tex files in one particular directory and whatever subdirectory of this directory.
I presume syntax: regexp will be required for this.
A brief explanation of the particular regular expression used, would also be very welcome, so that we can all learn a bit here.
Let's say you want to exclude the directory named exclude. The following regex would then match all files that end in .tex unless exclude/ comes somewhere before that:
^(?!.*\bexclude/).*\.tex$
In my .hgignore file, I am trying to ignore all generated xll files. I (unfortunately) have a directory called "xll" within the domain of the repository, and I do not want to ignore the directory itself.
I have tried:
syntax: regex
\.xll$
which I thought should mean "match all that ends in '.xll'"
and
syntax: regex
*.\.xll$
which I thought should mean "match all that have at least one arbitrary character, followed by '.xll'".
With either of the above, the directory is not ignored (yay) but neither is a file foobar.xll (darn). If I use a bare "xll" with regex, or "*.xll" with glob, both the directory and the file are ignored.
This is in linux (Ubuntu 10.04.4) with hg 2.6 (TortoiseHG 2.8) (I'm observing the effect in Nautilus via the presence or absence of "X" icons).
Thanks in advance!
EDIT
(adding comments in here as they are too long to fit in a comment...)
Thanks for all the responses. Turns out I was misinterpreting some things. So:
- because I used "regex" instead of "regexp" (and I had "glob" at top of file), whatever I put on the line that referred to "xll" was being interpreted by "glob", so the line did have an effect (which made me think, incorrectly, that the "syntax: regex" line was doing what I thought it was
- by coincidence, all the files in my "xll" directory were filtered out (as they should have been) by other lines in .hgignore, and not by the "*.xll" line
- consequently, in Nautilus, the xll directory was marked as "ignored", not because the filter ignoring the entire directory, but instead because other filters were filtering all files within that directory
Bottom line, the *.xll I had under "syntax: glob" was actually filtering out files exactly as desired. The feedback in Nautilus was just different than I expected.
It's .*\.xll$, not *.\.xll$.
Using glob syntax works well for me:
syntax: glob
*.xll
When I create a directory named xll with an untracked file, I still see the file in the output from hg status:
$ mkdir xll
$ touch a.xll x.txt xll/b.xll xll/y.txt
$ echo 'syntax: glob\n*.xll' > .hgignore
$ hg status
? .hgignore
? x.txt
? xll/y.txt
Using \.xll$ with syntax: regexp also works great for me.
