* util.stanza: Add method for extracting a single attribute valueKim Alvefur2022-08-171-0/+8
| | | | | | | | | Sometimes you only care about a single attribute, but the child tag itself may be optional, leading to needing `tag and tag.attr.foo` or `stanza:find("tag@foo")`. The `:find()` method is fairly complex, so avoiding it for this kind of simpler use case is a win.
* util.stanza: Create tables with correct size to avoid reallocationsKim Alvefur2022-03-181-2/+15
| | | | | Potential performance gain since the tables don't need to be resized as they grow to the final size.
* util.stanza: Use table.move in cloneKim Alvefur2022-03-181-9/+6
| | | | Code reduction, potentially a performance gain.
* util.stanza: Remove dead codeKim Alvefur2021-12-311-5/+0
| | | | | These cases are caught by `check_text(v, ..)` above. Those errors do not contain the attribute however, which would have been nice.
* util.stanza: Make type error message consistent with othersKim Alvefur2021-12-311-1/+1

* util.stanza: Adjust pretty printing for symmetryKim Alvefur2021-11-291-1/+1
| | | | | Self-closing <tags/> and <?processing instructions?> had some asymmetries in applied colors.
* util.stanza: Add :get_child_with_attr() + testsMatthew Wild2021-09-121-0/+8

* util.stanza: Export pretty printing functionKim Alvefur2021-06-291-1/+3

* util.stanza: Simplify and make pretty-printing look nicerKim Alvefur2020-11-071-29/+37
| | | | | | | | | | | | | | I've had this color theme in a local debug module for some time and I quite like it. The colors are from the XMPP logo. Removes extra XML serialization implementation in favor of the standard one. Also removes recursive str=str..more string building. The new two-level gsub has the accumulator in C space so shouldn't be too bad. The inner gsub calls use no callback, so should be fast and not create all that much garbage. No serious benchmarking has been done, but who cares if it looks nice?
* util.stanza: Remove Windows "support" (disabling ANSI color pretty printing)Kim Alvefur2020-11-071-11/+2
| | | | | | Always enable pretty printing if util.termcolours is available util.termcolours can be nooped out to disable pretty printing.
* util.stanza: add at_top helperJonas Schäfer2021-05-081-0/+4
| | | | | | This allows the user to detect whether the cursor is currently at the top of the stanza. This will be used by util.xmppstream to be able to port it over.

| * util.stanza: Move misplaced argument to correct placeKim Alvefur2020-12-241-2/+2
| | | | | | | | | | valid_utf8() takes only one argument, so the false was probably meant to be valid_xml_cdata(text, attribute=false)

* | util.stanza: Add method returning stanza with added indentationKim Alvefur2020-04-121-0/+30
| | | | | | | | | | Adds indentation and line breaks to stanzas, to make stanzas easier to read for humans.
* | util.stanza: Accept util.error object to error_replyKim Alvefur2019-12-141-0/+3
| | | | | | | | | | | | | | | | If we're moving towards util.error as the standard error container then this makes sense. This may allow for future extensibility without needing a lot of optional arguments.
* | util.stanza: Support the 'by' attribute on errorsKim Alvefur2019-11-251-2/+5
| | | | | | | | | | This is to be used when the entity generating the error is not the same as the one the stanza was directed to, e.g. an intermediate server.

* util.stanza: Don't automatically generate ids for iq stanzasMatthew Wild2018-09-131-9/+4
| | | | | | | | | | Users of this API should provide their own id attribute that meets their uniqueness requirements. The current implementation leaks information (i.e. how many iq stanzas have been sent by the server to other JIDs). Providing any strong guarantees of randomness here would need to pull in additional dependencies that we don't want in this simple library.
