The global configuration file for cabal-install is~/.cabal/config. If you do not have this file, cabal will createit for you on the first call to cabalupdate. Alternatively, you canexplicitly ask cabal to create it for you using

You can change the location of the global configuration file by specifyingeither --config-file=FILE on the command line or by setting theCABAL_CONFIG environment variable.

Most of the options in this configuration file are also available ascommand line arguments, and the corresponding documentation can be usedto lookup their meaning. The created configuration file only specifiesvalues for a handful of options. Most options are left at their defaultvalue, which it documents; for instance,

means that the configuration file currently does not specify a value forthe executable-stripping option (the line is commented out), andthat the default is True; if you wanted to disable stripping ofexecutables by default, you would change this line to

You can also use cabaluser-configupdate to migrate configurationfiles created by older versions of cabal.

3.1.2. Environment variables¶

Various environment variables affect cabal-install.

The variable to find global configuration file.

Default content directory for cabal-install files.Default value is getAppUserDataDirectory'cabal', which is$HOME/.cabal on unix systems and %APPDATA%cabal in Windows.

Note

The CABAL_DIR might be dropped in the future, whencabal-install starts to use XDG Directory specification.

The override for default dist build directory.Note, the nix-style builds build directory (dist-newstyle)is not affected by this environment variable.

3.1.2.1. Configuration file discovery¶

1. If $CABAL_CONFIG is set use it,

2. otherwise if $CABAL_DIR is set use $CABAL_DIR/config

3. otherwise use getAppUserDirectory'cabal'

If the configuration file doesn't exist cabal-installwill generate the default one, with directories based on$CABAL_DIR (if set) or getAppUserDirectory'cabal' prefix.

3.1.3. Repository specification¶

An important part of the configuration is the specification of therepository. When cabal creates a default config file, it configuresthe repository to be the central Hackage server:

The name of the repository is given on the first line, and can beanything; packages downloaded from this repository will be cached under~/.cabal/packages/hackage.haskell.org (or whatever name you specify;you can change the prefix by changing the value ofremote-repo-cache). If you want, you can configure multiplerepositories, and cabal will combine them and be able to downloadpackages from any of them.

3.1.3.1. Using secure repositories¶

For repositories that support the TUF security infrastructure (thisincludes Hackage), you can enable secure access to the repository byspecifying:

The and values are used forbootstrapping. As part of the TUF infrastructure the repository willcontain a file root.json (for instance,http://hackage.haskell.org/root.json) which the client needs to doverification. However, how can cabal verify the root.json fileitself? This is known as bootstrapping: if you specify a list of rootkey IDs and a corresponding threshold, cabal will verify that thedownloaded root.json file has been signed with at least keys from your set of .

Cabal Server Files 2018

You can, but are not recommended to, omit these two fields. In that casecabal will download the root.json field and use it withoutverification. Although this bootstrapping step is then unsafe, allsubsequent access is secure (provided that the downloaded root.jsonwas not tampered with). Of course, adding root-keys andkey-threshold to your repository specification only shifts theproblem, because now you somehow need to make sure that the key IDs youreceived were the right ones. How that is done is however outside thescope of cabal proper.

More information about the security infrastructure can be found athttps://github.com/haskell/hackage-security.

3.1.3.2. Local no-index repositories¶

It's possible to use a directory of .tar.gz package files as a local packagerepository.

cabal will construct the index automatically from thepackage-name-version.tar.gz files in the directory, and will use optionalcorresponding package-name-version.cabal files as new revisions.

For example, if /absolute/path/to/directory looks like

then cabal will create an index with two packages:

• foo-0.1.0.0 using the source and .cabal file insidefoo-0.1.0.0.tar.gz

• bar-0.2.0.0 using the source inside bar-0.2.0.0.tar.gzand bar-0.2.0.0.cabal

The index is cached inside the given directory. If the directory is notwritable, you can append #shared-cache fragment to the URI,then the cache will be stored inside the remote-repo-cache directory.The part of the path will be used to determine the cache key part.

Note

cabal-install creates a .cache file, and will aggressively useits contents if it exists. Therefore if you change the contents ofthe directory, remember to wipe the cache too.

Note

The URI scheme file: is interpreted as a remote repository,as described in the previous sections, thus requiring manual constructionof 01-index.tar file.

3.1.3.3. Legacy repositories¶

Currently cabal supports single kind of 'legacy' repositories.It is specified using

This is just syntactic sugar for

although, in (and only in) the specific case of Hackage, the URLhttp://hackage.haskell.org/packages/archive will be silentlytranslated to http://hackage.haskell.org/.

3.1.3.4. Secure local repositories¶

If you want to use repositories on your local file system, it isrecommended instead to use a secure local repository:

The layout of these secure local repos matches the layout of remoterepositories exactly; the hackage-repo-toolcan be used to create and manage such repositories.

We are living in a tech-savvy world where Artificial Intelligence has grasped every aspect of our lives. The entire world goes hand in hand with technology and the web. Each and every detail, starting from minute to large information is stored on the web as data. Since nothing is picture-perfect in this world, there are also some flaws associated with data, mostly with the deleted files… However, there are several solutions available to recover deleted files from the server. Did you ever encounter the problem of losing important data on your PC, hard drives or USB?

100% possibility is there to retrieve these lost data files and that too without any hassle. Henceforth, follow this user guide to know effective ways to manage this task. Let's have a look at the useful tips in order to recover deleted files from the server.

Efficacious Ways to Recover Deleted Files from Server

When you have mistakenly deleted data from a specific device, then stop using that device and proceed with the data recovery process in no time. 3 proven ways pertaining to how to recover deleted files from the server.

Fix 1: Recover Deleted Files from Recycle Bin

If you just remove the files on your PC by placing that to the Recycle Bin and don't click on the Empty Recycle Bin button, you can get them back at ease. Simply, you need to open the Recycle Bin. After that, spot and press the files you wish and select the Restore option. This will restore the deleted files back to the previous position.

Fix 2: Retrieve the Older Version of Lost File

If you have already done the blunder of emptying the Recycle Bin, you can make an attempt to restore an older version of the deleted file with a free backup and in-built restore feature. To recover deleted files from the server, follow the below steps:

Windows 7

1. First, you need to press the Start button.
2. Then, you need to hover on to the folder containing the specified file. After that, you just need to right-click on the folder. Next, you need to press the Restore Previous Versions option.
3. After that, you will find a list of previous versions of the deleted files. Then, you need to select what you like. Moreover, press Restore in order to recover deleted files from the server.

Windows 10

1. You need to open the folder which contains the deleted file and press History button.
2. Now, you will see the File History which will display the entire list of files containing the latest backup of the folder.
3. Then, you need to press the Previous button in order to locate. Furthermore, you have to choose the file which you wish to retrieve. Next, press the Restore button to bring it back.

Fix 3: Restore the Deleted Files using Software

If you wish to retrieve the same copy of the deleted files, you can use any kind of data recovery software. Also, this software is built to combat these abrupt data loss situations like deleted recovery, format recovery, system crash, raw error, and many more.

It helped most of the users to retrieve lost files from the desktop, external hard disks, as well as USB devices. Just you need to follow the basic steps:

1. Choose a particular file location and then press the Scan button.
2. After that, you need to scan the entire storage device. You can see the quick scan result which shows Deleted Files. This is the place where you can find all the deleted files as well as folders.
3. Then, you need to preview the files. In the Deleted files option, you will get to know the wanted files by following a certain path. Then, you need to use the Filter feature to spot the abandoned files. Double-click on the data will help you preview that.
4. Finally, you need to select all the target files and press the Recover button.
5. Please examine all the scan results in each and every tab for the deleted files.

How to Recover Deleted Files from Server?

When data loss occurs, you need to stop using P.C or other external storage devices. This can safeguard the lost files for the purpose of data recovery. which can be overwritten if you continue using the same. When you press a particular file and press Delete, the system conceals the data by deleting the file directory and mark it as free.

In such a situation, you can easily recover deleted files from the server through the rebuild of the file directory. The data in that space is not removed until you get the space.
