Next to file.nix we get src-for-file.nix
|
||||
src-for-file.nix should evaluate to a flat attribute set with
|
||||
string values.
|
||||
It is supposed to be imported in the main expression.
|
||||
In the ideal world it can export url, hash, version.
|
||||
|
||||
src-for-file.nix generation is directed by
|
||||
src-info-for-file.nix.
|

|

Attributes:
|

|

src-info-for-file.nix:
|

|

downloadPage
|

rev (for repos)
|

baseName (default = unnamed-package)

sourceRegexp (default = '.*[.]tar[.].*')

choiceCommand (default = 'head -1')

update-walker is an imperative semiautomated update helper.
|
||||
|
||||
It runs the X.upstream file to find the freshest version of the package in
|
||||
the specified upstream source and updates the corresponding X.nix file.
|
||||
|
||||
|
||||
|
||||
The simplest available commands:
|
||||
|
||||
url: set the upstream source list URL equal to $1; the default is
|
||||
meta.downloadPage with meta.homepage fallback
|
||||
|
||||
dl_url_re: set the regular expression used to select download links to $1; the
|
||||
default is meta.downloadURLRegexp or '[.]tar[.]([^./])+\$' if it is not set
|
||||
|
||||
target: specify target expression; default is to replace .upstream extension
|
||||
with .nix extension
|
||||
|
||||
name: specify the derivation name; default is the basename of the dirname
|
||||
of the .upstream file
|
||||
|
||||
attribute_name: specify the attribute name to evaluate for getting the current
|
||||
version from meta.version; default is to use the derivation name
|
||||
|
||||
minimize_overwrite: set config options that mean that only version= and
|
||||
sha256= have to be replaced; the default is to regenerate a full upstream
|
||||
description block with url, name, version, hash etc.
|
||||
|
||||
|
||||
|
||||
A lot of packages can be updated in a pseudo-declarative style using only
|
||||
the commands from the previous paragraph.
|
||||
|
||||
Some packages do not need any non-default settings, in these case just setting
|
||||
meta.updateWalker to true is enough, you can run update-walker directly on the
|
||||
.nix file afterwards. In this case minimize_overwrite it implied unless
|
||||
meta.fullRegenerate is set.
|
||||
|
||||
|
||||
|
||||
The packages that require more fine-grained control than the described options
|
||||
allow, you need to take into account the default control flow of the tool.
|
||||
|
||||
First, the definitions from update-walker script and additional definitions
|
||||
from update-walker-service-specific.sh are loaded. Then the config is executed
|
||||
as a shell script. Some of the commands it can use do remember whether they
|
||||
have been used. Afterwards the following steps happen:
|
||||
|
||||
attribute_name is set to name unless it has been already set
|
||||
|
||||
meta.version is read from the NixPkgs package called attribute_name
|
||||
|
||||
download URL regexp is set to default unless it has been already set in the
|
||||
updater script
|
||||
|
||||
the download page URL gets set to default value unless it has been set
|
||||
previously
|
||||
|
||||
if the action of getting the download page and choosing the freshest link by
|
||||
version has not yet been taken, it happens
|
||||
|
||||
if the version has not yet been extracted from the URL, it gets extracted
|
||||
|
||||
target nix expression to update gets set to the default value unless it has
|
||||
been set explicitly
|
||||
|
||||
if the URL version is fresher than the packaged version, the new file gets
|
||||
downloaded and its hash is calculated
|
||||
|
||||
do_overwrite function is called; the default calculates a big upstream data
|
||||
block and puts it after the '# Generated upstream information' marker (the
|
||||
marker can be changed by the command marker)
|
||||
|
||||
|
||||
|
||||
If the update needs some special logic, it is put into the updater script and
|
||||
the corresponding steps are skipped because the needed action has already been
|
||||
performed.
|
||||
|
||||
For example:
|
||||
|
||||
minimize_overwrite is exactly the same as
|
||||
|
||||
do_overwrite() { do_overwrite_just_version; }
|
||||
|
||||
redefinition. You can do a more complex do_overwrite redifinition, if needed.
|
||||
It can probably use ensure_hash to download the source and calculate the hash
|
||||
and set_var_value.
|
||||
|
||||
set_var_value alters the $3-th instance of assigning the $1 name in the
|
||||
expression to the value $2. $3 defaults to 1. It can modify $4 instead of the
|
||||
current target, it can put the value without quotes if $5 is 1.
|
||||
|
||||
|
||||
|
||||
Typical steps include:
|
||||
|
||||
ensure_choice: download current URL and find the freshest version link on the
|
||||
page, it is now the new URL
|
||||
|
||||
ensure_hash: download current URL and calculate the source package hash
|
||||
|
||||
ensure_version: extract version from the URL
|
||||
|
||||
SF_redirect: replace the current URL with a SourceForge.net mirror:// URL
|
||||
|
||||
SF_version_dir: assume SourceForge.net layout and choose the freshest
|
||||
version-named subdirectory in the file catalog; you can optionally specify $1
|
||||
as a directory name regexp (digits and periods will be required after it)
|
||||
|
||||
SF_version_tarball: assume SourceForge.net layout and choose the freshest
|
||||
tarball download link
|
||||
|
||||
version: apply replacement of $1 with $2 (extended regexp format) to extract
|
||||
the version from URL
|
||||
|
||||
version_link: choose the freshest versioned link, $1 is the regexp of
|
||||
acceptable links
