.SH "NAME"
sbolint \- check SlackBuild directories or tarballs for common errors.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBsbolint\fR [\-a] [\-g] [\-q] [\-u] [\-n] [build [build ...]]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
sbolint checks for common errors in SlackBuilds.org scripts. It's
intended for slackbuild authors and maintainers, and can cut down on
\&\*(L"There was a problem with your upload\*(R" errors from the submission form.
.PP
The [build] arguments must be either directories or tarballs, each
containing a SlackBuild script, slack-desc, \s-1README,\s0 and .info file.
With no [build] arguments, the current directory is checked.
.PP
sbolint will flag errors for problems that would prevent the build from
being accepted by the upload form (or by the SBo admins, if if passes
the upload checks). There may also be warnings, which are things that
(probably) won't stop your build from being accepted, but may cause the
SBo admins extra work.
.PP
sbolint was not written by the SlackBuilds.org team, and shares no code
with the upload form's submission checker. Lack of errors/warnings from
sbolint does not guarantee that your build will be accepted!
.PP
sbolint doesn't check built packages, and never executes the build
script. If you want a lint tool for binary Slackware packages, try
pprkut's \fBlintpkg\fR.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-a\fR" 4
.IX Item "-a"
Check all builds in the git repository. This must be run from within a
git tree (e.g. one made with \*(L"git clone\*(R").
.IP "\fB\-q\fR" 4
.IX Item "-q"
Quiet. Suppresses 'xxx checks out \s-1OK\s0' and the total errors/warnings summary.
.IP "\fB\-u\fR" 4
.IX Item "-u"
\&\s-1URL\s0 check. Uses \fBcurl\fR to make \s-1HTTP HEAD\s0 requests for the \fB\s-1HOMEPAGE\s0\fR,
\&\fB\s-1DOWNLOAD\s0\fR, and \fBDOWNLOAD_x86_64\fR links. This won't guarantee that
the links are good, but some kinds of failure (e.g. site down, 404)
means they're definitely bad. Unfortunately a lot of sites have stopped
responding to \s-1HEAD\s0 requests in the name of \*(L"security\*(R", so your mileage
man vary.
.IP "\fB\-n\fR" 4
.IX Item "-n"
Suppress warnings. Only errors will be listed. This also affects the
exit status (see below).
.SH "CHECKS"
.IX Header "CHECKS"
For tar files only:
.IP "\-" 4
File size must not be bigger than the upload form's limit (currently one
megabyte).
.IP "\-" 4
File must be a tar archive, possibly compressed with gzip, bzip2, or xz,
extractable by the \fBtar\fR(1) command.
.IP "\-" 4
Filename extension must match compression type.
.IP "\-" 4
Archive must contain a directory with the same name as the archive's base name,
e.g. \fIfoo.tar.gz\fR must contain \fIfoo/\fR. Everything else in the archive must be
inside this directory.
.IP "\-" 4
Archive must contain \fIdirname/Idirname.SlackBuild\fR.
.PP
For all builds:
.IP "\-" 4
The SlackBuild, .info, \s-1README\s0 files must have Unix \en line endings (not
\&\s-1DOS\s0 \er\en), and the last line of each must have a \en.
.IP "\-" 4
The SlackBuild script must exist, with mode 0755 (or 0644, if in a git repo),
and be a \fI#!/bin/bash\fR script.
.IP "\-" 4
The script must contain the standard variable assignments for \s-1PRGNAM,
VERSION, BUILD,\s0 and \s-1TAG. BUILD\s0 must be numeric.
.IP "\-" 4
\&\fI\s-1PRGNAM\s0\fR in the script must match \fI\s-1PRGNAM\s0\fR in the .info file. Both must
match the script name (\fI\s-1PRGNAM\s0.SlackBuild\fR) and the directory name.
.IP "\-" 4
\&\fI\s-1VERSION\s0\fR must match the \fI\s-1VERSION\s0\fR in the .info file.
.IP "\-" 4
TAG=${TAG:\-_SBo} must occur in the script.
.IP "\-" 4
The \fI\s-1VERSION\s0\fR, \fI\s-1BUILD\s0\fR, and \fI\s-1TAG\s0\fR variables must respect the environment.
.IP "\-" 4
The script must install the slack-desc in \fI\f(CI$PKG\fI/install\fR.
.IP "\-" 4
If there is a doinst.sh script, the SlackBuild must install it to \fI\f(CI$PKG\fI/install\fR.
.IP "\-" 4
Template boilerplate comments should be removed, e.g. \fI\*(L"\s-1REMOVE THIS ENTIRE BLOCK OF TEXT\*(R"\s0\fR
or \fI\*(L"Automatically determine the architecture we're building on\*(R"\fR.
.IP "\-" 4
Script must contain exactly one \fBmakepkg\fR command.
.IP "\-" 4
\&\s-1README\s0 must exist, have mode 0644, its character encoding must be
either \s-1ASCII\s0 or \s-1UTF\-8\s0 without \s-1BOM,\s0 and it may not contain tab characters.
.IP "\-" 4
slack-desc must exist, have mode 0644, its character encoding must be \s-1ASCII,\s0
and it may not contain tab characters.
.IP "\-" 4
slack-desc contents must match the SBo template, including the \*(L"handy-ruler\*(R",
comments, and correct spacing/indentation.
.IP "\-" 4
\&.info file must exist, have mode 0644, and match the SBo template.
.IP "\-" 4
\&.info file URLs must be valid URLs (for a very loose definition of \*(L"valid\*(R": they
must begin with \fBftp://\fR, \fBhttp://\fR, or \fBhttps://\fR).
.IP "\-" 4
Optionally, .info file URLs can be checked for existence with an \s-1HTTP HEAD\s0
request (see the \fB\-u\fR option).
.PP
The following tests are only done when sbolint's starting directory
was \s-1NOT\s0 in a git repo:
.IP "\-" 4
Any files other than the .SlackBuild, .info, slack-desc, and \s-1README\s0 are
checked for permissions (should be 0644) and excessive size.
.IP "\-" 4
The source archive(s) must not exist. Also sbolint attempts to detect
extracted source trees (but isn't all that good at it).
.IP "\-" 4
Files named 'build.log' or 'strace.out*' must not exist. The \fBsbrun\fR
tool creates these.
.PP
The rationale for skipping the above tests when in a git repo is that
maintainers will be using git to track files and push changes, so we
don't need to check them here.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
Exit status from sbolint will normally be 0 (success) if there were no
errors or warnings in any of the builds checked. With the \fB\-n\fR option,
exit status will be 0 if there are no errors.
.PP
Exit status 1 indicates there was at least one warning or error (or, with
\&\fB\-n\fR, at least one error).
.PP
Any other exit status means sbolint itself failed somehow (e.g. called
with nonexistent filename).
.SH "BUGS"
.IX Header "BUGS"
Probably quite a few. Watch this space for details.
.SH "AUTHOR"
.IX Header "AUTHOR"
B. Watson (yalhcru at gmail dot com, or Urchlay on Libera \s-1IRC\s0)
