You can change the format string — in fact, just let the user - configuration provide it — without having to worry about argument - evaluation problems. Positional and optional arguments are simply freely - choosable. - - • memory containers, auto-sizing string ops (HXmc_*) - - At the cost of slightly increased number memory allocations as you work - with the buffers, the hmc collection of functions provide scripting-level - semantics for strings. Appending to a string is simply hmc_strcat(&s, - "123") [cf. $s .= "123"], without having to worry about overflowing a - buffer. - - • option parsing (HXoption_*) - - Put blunt, libpopt failed to do some elementary things and there was no - maintainer to fix it. Well, it's packaged with rpm which already diverged - in all distros. - HXoption is table- and callback-based, much like popt. - - • shellconfig parser (HXshconfig_*) - - Parsers shconfig files. Their format is a subset of shell code. Files in / - etc/sysconfig are commonly shconfig-style. - - • common string operations - - basename, chomp, dirname, getl(ine), split, strlower/-upper, str*trim, - strsep, strsep2, etc. - -This page was last modified: 2011-01-15 16:41 UTC libHX.sf.net - -# Generated using `w3m -dump libhx.sf.net` and slightly editing it. @@ -1,6 +1,6 @@ -# generated automatically by aclocal 1.15.1 -*- Autoconf -*- +# generated automatically by aclocal 1.16.5 -*- Autoconf -*- -# Copyright (C) 1996-2017 Free Software Foundation, Inc. +# Copyright (C) 1996-2021 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, @@ -14,13 +14,13 @@ m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl -m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, -[m4_warning([this file was generated for autoconf 2.69. +m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.71],, +[m4_warning([this file was generated for autoconf 2.71.

Especially for +“atomic” and “small” data, it might be easier to just let HXdeque do the +management. Compare the following two code examples to store strings in a +HXdeque: + +.. code-block:: c + + int main(int argc, const char **argv) + { + struct HXdeque *dq = HXdeque_init(); + while (--argc) + HXdeque_push(dq, ++argv); + return 0; + } + +...and to store strings in a HXlist: + +.. code-block:: c + + struct element { + struct HXlist_head list; + char *data; + }; + + int main(int main, const char **argv) + { + HXLIST_HEAD(lh); + while (--argc) { + struct element *e = malloc(sizeof(*e)); + e->data = *++argv; + HXlist_init(&e->list); + HXlist_add_tail(&e->list); + } + return 0; + } + +These examples assume that ``argv`` is persistent, which, for the sample, is +true. + +With HXlist, one needs to have a struct with a ``HXlist_head`` in it, and if +one does not already have such a struct, e.g. by means of wanting to store more +than just one value, one will need to create it first, as shown, and this may +lead to an expansion of code. + +This however does not mean that HXlist is the better solution over HXdeque for +data already available in a struct. As each struct has a ``list_head`` that is +unique to the node, it is not possible to share this data. Trying to add a +HXlist_head to another list is not going to end well, while HXdeque has no +problem with this as list heads are detached from the actual data in HXdeque. + +Data can be added multiple times in a HXdeque without ill effects: + +.. code-block:: c + + struct point p = {15, 30}; + HXdeque_push(dq, &p); + HXdeque_push(dq, &p); + +To support this, an extra allocation is needed on the other hand. In a HXlist, +to store *n* elements of compound data (e.g. ``struct point``), *n* allocations +are needed, assuming the list head is a stack object, and the points are not. +HXdeque will need at least *2n+1* allocations, *n* for the nodes, *n* for the +points and another for the head. diff --git a/doc/install.rst b/doc/install.rst new file mode 100644 index 0000000..a0931b4 --- /dev/null +++ b/doc/install.rst @@ -0,0 +1,50 @@ +============ +Installation +============ + +libHX uses GNU autotools as a build environment, which means that +all you have to run as a end-user is the configure with any +options that you need, plus the usual make and make install as +desired. + +Pay attention to multi-lib Linux distributions where you most +likely need to specify a different libdir instead of using the +default “lib”.

-\begin_layout Standard -This makes it quite similar to the string operations (and append seems to - be the most commonly used one to me) supported in scripting languages that - also do without a size argument. - The essential part of such memory containers is that their internal (hidden) - metadata structure contains the length of the memory block in the container. - For binary data this may be the norm, but for C-style strings, the stored - and auto-updated length field serves as an accelerator cache. - For more details, see -\family typewriter -HXmc_length -\family default -. -\end_layout - -\begin_layout Standard -Of course, the automatic management of memory comes with a bit of overhead - as the string expands beyond its preallocated region. - Such may be mitigated by doing explicit (re)sizing. -\end_layout - -\begin_layout Subsection -Structural overview -\end_layout - -\begin_layout Standard -HXmc functions do not actually return a pointer to the memory container - (e. -\begin_inset space \thinspace{} -\end_inset - -g. -\begin_inset space \space{} -\end_inset - - -\family typewriter -struct -\family default -) itself, but a pointer to the data block. - Conversely, input parameters to HXmc functions will be the data block pointer. - It is of type -\family typewriter -hxmc_t -\begin_inset space ~ -\end_inset - -* -\family default -, which is typedef'ed to -\family typewriter -char -\begin_inset space ~ -\end_inset - -* -\family default - and inherits all properties and privileges of -\family typewriter -char -\begin_inset space ~ -\end_inset - -* -\family default -. - Pointer arithmetic is thus supported. - It also means you can just pass it to functions that take a -\family typewriter -char -\begin_inset space ~ -\end_inset - -* -\family default - without having to do a member access like -\family typewriter -s.c_str -\family default -. - The drawback is that many functions operating on the memory container need - a -\family typewriter -hxmc_t -\begin_inset space ~ -\end_inset - -** -\family default - (a level-two indirection), because not only does the memory block move, - but also the memory container itself. - This is due to the implementation of the container metadata which immediately - and always precedes the writable memory block. -\end_layout - -\begin_layout Standard -HXmc ensures that the data block is terminated by a NUL ( -\family typewriter -' -\backslash -0' -\family default -) byte (unless you trash it), so you do not have to, and of course, to be - on the safe side. - But, the automatic NUL byte is not part of the region allocated by the - user. - That is, when one uses the classic approach with -\family typewriter -malloc(4096) -\family default -, the user will have control of 4096 bytes and has to stuff the NUL byte - in there somehow on his own; for strings this means the maximum string - length is 4095. - Requesting space for a 4096-byte sized HXmc container gives you the possibility - to use all 4096 bytes for the string, because HXmc provides a NUL byte. -\end_layout -

Abstract types are: + +``HXMAPT_DEFAULT`` + No further preferences or guarantees; selects any data structure that the + libHX maintainer deemed fast. + +``HXMAPT_ORDERED`` + The map shall use a data structure that provides ordered traversal. + +Specific types include: + +``HXMAPT_HASH`` + Hash-based map – Amortized O(1) insertion, lookup and deletion; + unordered. + +``HXMAPT_RBTREE`` + Red-black binary tree – O(log(n)) insertion, lookup and deletion; + ordered. + +These can then be used with the initialization functions: + +.. code-block:: c + + struct HXmap *HXmap_init(unsigned int type, unsigned int flags); + struct HXmap *HXmap_init5(unsigned int type, unsigned int flags, const struct HXmap_ops *ops, size_t key_size, size_t data_size); + +Both the *init* and *init5* variant creates a new map; the latter function +allows to specify the operations in detail as well as key and data size, which +may become necessary when using data sets which have their own way of being +managed. The flags parameter can contain any of the following: + +``HXMAP_NONE`` + This is just a mnemonic for the value 0, indicating no flags. + +``HXMAP_NOREPLACE`` + If a key already exists and another add operation is attempted, the + key's associated value will be replaced by the new value.

In the flag's + absence, direct value comparison will be used if the key size is + specified as zero (e.g. with the ``HXhashmap_init4`` function call), or + ``memcmp`` if the key size is non-zero. + +``HXMAP_CKEY`` + Instructs the map to make copies of keys when they are added to the + map. This is required when the buffer holding the key changes or goes + out of scope. The flag presets the ``k_clone`` and ``k_free`` + operations to ``HX_memdup`` and ``free``, and as such, the ``key_size`` + parameter must not be zero.

The return value is the same as that of + ``memcmp`` or ``strcmp``: negative values indicate that the first key + is “less than” the second, zero indicates that both keys are equal, and + positive values indicate that the first key is “greater than” the + second. The ``size`` argument in third position is provided so that + ``memcmp``, which wants a size parameter, can directly be used without + having to write an own function. (This also means strcmp can't be + directly plugged in due to a function signature mismatch.) + +``k_clone`` + Function that will clone (duplicate) a key. This is used for keys that + will be added to the tree, and potentially also for state-keeping + during traversal of the map.

Since ``HXmap_get`` may legitimately return ``NULL`` + if ``NULL`` was stored in the tree as the data for a given key, only + ``errno`` will really tell whether the node was found or not; in the + latter case, ``errno`` is set to ``ENOENT``. + +``HXmap_del`` + Removes an element from the map and returns the data value that was + associated with it. When an error occurred, or the element was not + found, ``NULL`` is returned. Because ``NULL`` can be a valid data + value, ``errno`` can be checked for non-zero. ``errno`` will be + ``-ENOENT`` if the element was not found, or zero when everything was + ok. + +``HXmap_free`` + The function will delete all elements in the map and free memory it + holds. + +``HXmap_keysvalues`` + Returns all key-value-pairs in an array of the size as many items were + in the map (map->items) at the time it was called.

Traversers are returned even if the map has + zero elements. + +``HXmap_traverse`` + Returns a pointer to a ``struct HXmap_node`` for the next element / + key-value pair from the map, or ``NULL`` if there are no more entries. + +``HXmap_travfree`` + Releases the memory associated with a traverser. + +``HXmap_qfe`` + The “quick foreach”.

When this happens, the traverser will + stop, so as to not return entries twice. + +:Binary trees: + Elements may be added before the traverser's position. These elements + will not be returned in subsequent traversion calls. If the data + structure changes as a result of an addition or deletion, the traverser + will rebuild its state and continue traversal transparently. Because + elements in a binary tree are ordered, that is, element positions may + not change with respect to another when the tree is rebalanced, there + is no risk of returning entries more than once. Nor will elements that + are sorted after the current traverser's position not be returned + (= they will be returned, because they cannot get reordered to before + the traverser like in a hash map). The HX rbtree implementation also + has proper handling for when the node which is currently visiting is + deleted. + + +RB-tree Limitations +=================== + +The implementation has a theoretical minimum on the maximum number of nodes, +2^{24}=16{,}777{,}216. A worst-case tree with this many elements already has a +height of 48 (RBT_MAXDEP), which is the maximum height currently supported. The +larger the height is that HXrbtree is supposed to handle, the more memory +(linear increase) it needs. All functions that build or keep a path reserve +memory for RBT_MAXDEP nodes; on x86_64, this is 9 bytes per <node, direction> +pair, amounting to 432 bytes for path tracking alone. It may not sound like a +lot to many, but given that kernel developers try to limit their stack usage to +some 4096 bytes is impressive alone. + + +Examples +======== + +Case-insensitive ordering +------------------------- + +The correct way: + +.. code-block:: c + + static int my_strcasecmp(const void *a, const void *b, size_t z) { + return strcasecmp(a, b); + } + static const struct HXmap_ops icase = { + .k_compare = my_strcasecmp, + }; + HXmap_init5(HXMAPT_RBTREE, HXMAP_SKEY, &icase, 0, dsize); + +A hackish way (which wholly depends on the C implementation and use of extra +safeguards is a must): + +.. code-block:: c + + static const struct HXmap_ops icase = { + .k_compare = (void *)strcasecmp, + }; + BUILD_BUG_ON(sizeof(DEMOTE_TO_PTR(strcasecmp)) > sizeof(void *)); + BUILD_BUG_ON(sizeof(DEMOTE_TO_PTR(strcasecmp)) > sizeof(icase.k_compare)); + HXmap_init5(HXMAPT_RBTREE, HXMAP_SKEY, &icase, 0, dsize); + + +Reverse sorting order +--------------------- + +Any function that behaves like strcmp can be used.

The essential part of such memory containers is that +their internal (hidden) metadata structure contains the length of the memory +block in the container. For binary data this may be the norm, but for C-style +strings, the stored and auto-updated length field serves as an accelerator +cache. For more details, see ``HXmc_length``. + +Of course, the automatic management of memory comes with a bit of overhead as +the string expands beyond its preallocated region. Such may be mitigated by +doing explicit (re)sizing. + + +Structural overview +=================== + +HXmc functions do not actually return a pointer to the memory container (e.g. +struct) itself, but a pointer to the data block. Conversely, input parameters +to HXmc functions will be the data block pointer. It is of type ``hxmc_t *``, +which is typedef'ed to ``char *`` and therefore has properties of a char +pointer. Pointer arithmetic is thus supported. It also means you can just pass +it to functions that take a ``char *`` without having to do a member access +like ``s.c_str()`` in C++. The drawback is that many functions operating on the +memory container need a ``hxmc_t **`` (a level-two indirection), because not +only does the memory block move, but also the memory container itself. This is +due to the implementation of the container metadata which immediately and +always precedes the writable memory block. + +HXmc ensures that the data block is terminated by the \0 byte (unless you trash +it), so you do not have to, and of course, to be on the safe side. But, the +automatic \0 byte is not part of the region allocated by the user. That is, +when one uses the classic approach with ``malloc(4096)``, the user will have +control of 4096 bytes and has to stuff the \0 byte in there somehow on his own; +for strings this means the maximum string length is 4095. Requesting space for +a 4096-byte sized HXmc container gives you the possibility to use all 4096 +bytes for the string, because HXmc provides a \0 byte. + +By the way, ``hxmc_t`` is the only typedef in this entire library, to +distinguish it from regular ``char *`` that does not have a backing memory +cointainer. + +Constructors, destructors +========================= + +.. code-block:: c + + #include <libHX/string.h> + + hxmc_t *HXmc_strinit(const char *s); + hxmc_t *HXmc_meminit(const void *ptr, size_t size); + void HXmc_free(hxmc_t *s); + void HXmc_zvecfree(hxmc_t **s); + +``HXmc_strinit`` + Creates a new ``hxmc_t`` object from the supplied string and returns + it. + +``HXmc_meminit`` + Creates a new ``hxmc_t`` object from the supplied memory buffer of the + given size and returns it. ``HXmc_meminit(NULL, len)`` may be used to + obtain an empty container with a preallocated region of len bytes (zero + is accepted for ``len``). + +``HXmc_free`` + Frees the hxmc object. + +``HXmc_zvecfree`` + Frees all hxmc objects in the ``NULL``-terminated array, and finally + frees the array itself, similar to ``HX_zvecfree``. + +Data manipulation +================= + +Binary-based +------------ + +.. code-block:: c + + hxmc_t *HXmc_trunc(hxmc_t **mc, size_t len);HXmc_trunc + hxmc_t *HXmc_setlen(hxmc_t **mc, size_t len);HXmc_setlen + hxmc_t *HXmc_memcpy(hxmc_t **mc, const void *ptr, size_t len); + hxmc_t *HXmc_memcat(hxmc_t **mc, const void *ptr, size_t len); + hxmc_t *HXmc_mempcat(hxmc_t **mc, const void *ptr, size_t len); + hxmc_t *HXmc_memins(hxmc_t **mc, size_t pos, const void *ptr, size_t len); + hxmc_t *HXmc_memdel(hxmc_t **mc, size_t pos, size_t len); + +When ``ptr`` is ``NULL``, each call behaves as if ``len`` would be ``zero``. +Specifically, no undefined behavior will result of the use of ``NULL``. + +``HXmc_trunc`` + Truncates the container's data to ``len`` size.

Additional flags can control the exact behavior of +``HX_getopt``: + +``HXOPT_PTHRU`` + “Passthrough mode”.

This behavior is also + implicit when the environment variable ``POSIXLY_CORRECT`` is set. + +``HXOPT_KEEP_ARGV`` + Do not modify ``argc`` and ``argv`` at all. + +The return value can be one of the following: + +``HXOPT_ERR_SUCCESS`` + Parsing was successful. + +``HXOPT_ERR_UNKN`` + An unknown option was encountered. + +``HXOPT_ERR_VOID`` + An argument was given for an option which does not allow one. In + practice this only happens with ``--foo=bar`` when ``--foo`` is of type + ``HXTYPE_NONE``, ``HXTYPE_VAL`` or ``HXTYPE_SVAL``.

To counter this +problem and have it doing the right thing, you must remove the static qualifier +on the options table when used with ``HXTYPE_STRDQ``, so that it will be +evaluated when it is first executed. + +It was not deemed worthwhile to have ``HXTYPE_STRDQ`` take an indirect +``HXdeque`` (``struct HXdeque **``) instead just to bypass this issue. (Live +with it.) + +Limitations +----------- + +The HX option parser has been influenced by both popt and Getopt::Long, but +eventually, there are differences: + +* Long options with a single dash (``-foo bar``). This unsupported + syntax clashes easily with support for option bundling or squashing. In case + of bundling, ``-foo`` might actually be ``-f -o -o``, or ``-f oo`` in case of + squashing. It also introduces redundant ways to specify options, which is not + in the spirit of the author. + +* Options using a ``+`` as a prefix, as in ``+foo``. Xterm for + example uses it as a way to negate an option. In the author's opinion, using + one character to specify options is enough — by GNU standards, a negator is + named ``--no-foo``. + +* Table nesting like implemented in popt. HXopt has no provision for nested + tables, as the need has not come up yet. It does however support chained + processing.

The + command is directly run without shell invocation, so no special character + expansion (wildcards, etc.) takes place. stdin is set to ``/dev/null``. The + parameter delimiter is the space character. To be able to use this function — + as it is relevant to security — the fmt table needs to have a key + with the magic value ``/libhx/exec``. + +* ``%(if condition,[then][,[else]])`` + + If the condition parameter expands to a string of non-zero length, the + function expands to the ``then`` block, otherwise the ``else`` block. The + delimiter used is a comma. + +* ``%(lower text)``, ``%(upper text)`` + + Lowercases or uppercases the supplied argument.

The use of this function is + deprecated, albeit no replacement is proposed. + + +Numbers to human-readable sizes with units +========================================== + +.. code-block:: c + + #include <libHX/string.h> + + char *HX_unit_size(char *out, size_t outsize, unsigned long long number, + unsigned int divisor, unsigned int cutoff); + char *HX_unit_size_cu(char *out, size_t outsize, + unsigned long long number, unsigned int divisor); + +``HX_unit_size`` takes an arbitrary number and and produces a more +readily-readable shortened (string) representation with a unit suffix. It does +this by dividing ``number`` by ``pow(divisor, i)`` for some integer _i_ such +that the resulting (integer) quotient is the highest possible value _v_ that is +less than ``cutoff``. This value _v_ is then emitted into ``out`` together with +the corresponding SI prefix. + +In other words, ``cutoff`` is the value when it attempts to do another +iteration of the division. For example, if the cutoff is set at 8192, +then 8191 will stay as-is, but 8192 is reduced to "8K". The popular +``wget`` utility implements a cutoff of 1024. + +Note that the SI prefix for one iteration (i==1), i.e. kilo, is a lower-case +``'k'``. If you need consistent upper-case output in your program, (i.e. K/M/G +instead of k/M/G), use a subsequent call to ``HX_strupper``. + +When ``divisor`` is 0, it defaults to 1000. When ``cutoff`` is 0, an +implementation-defined cutoff point is used. When ``cutoff`` is less than +``divisor``, the result is implementation-defined. + +The output number of ``HX_unit_size`` is always integer; no fractions are +emitted. This is rooted in the following idea: + +* An output like ``1G`` is quite broad and some precision would be nice. The + author has historically preferred 3 digits instead of just 2, thanks to wget + and rsync. + +* ``1.34G`` has the same string length as ``1340M``, i.e. both occupy the same + visual space in console outputs, but the latter has another digit of + precision. + +* By ditching fractions this way, ``HX_unit_size`` also sidesteps the issue of + excess digits being emitted (usually up to 5) from the trivial use (by + wget/rsync) of ``printf("%.2f", v)``. + +(With regard to the 1.34G-vs-1340M argument, do note that, to actually receive +"``1340M``" as output, you need to set a conveniently high cutoff value such +as 10000. Otherwise, you might get "``1G``".) + +The ``HX_unit_size_cu`` function will instead mimic the behavior of coreutils +(/usr/bin/df, /usr/bin/ls). That is, it divides ``number`` by ``pow(divisor, +i)`` for some integer _i_ such that the resulting (real) quotient is +less-than-or-equal ``divisor-1``. It rounds the value up to the next integer if +the fractional part is >90%, and if the quotient is greater-or-equal 10, the +fractional part is stripped and not emitted to ``out``. + +In practice, the rounding up of ``HX_unit_size_cu`` lends itself to display +occupying sizes, whereas the implicit rounding down (of integer divisions) +in ``HX_unit_size`` lend itself to sizes in progress meters. + + +Unit-suffixed numbers to full numbers +===================================== + +.. code-block:: c + + #include <libHX/string.h> + + double HX_strtod_unit(const char *s, char **end, + unsigned int exponent); + unsigned long long HX_strtoull_unit(const char *s, char **end, + unsigned int exponent); + +The ``HX_strtod_unit`` and ``HX_strtoull_unit`` functions behave similar to +``strtod`` and ``strtoul``, respectively, in that they convert the initial part +of the string in ``s`` to a ``double`` and ``unsigned long long``, +respectively, and apply the selected multiplication factor from ``exponent`` in +resolving an optional unit suffix. + +Upon overflow, ``errno`` is set to ``ERANGE`` just like the stdlib functions. +Unlike some implementations of ``strtoul``, negative numbers are outright +rejected. + +.. code-block:: c + + unsigned long long bytes = HX_strtoull_unit("1.5G", NULL, 1024); + + +Conversion from/to human-readable durations with units +====================================================== + +.. code-block:: c + + #include <libHX/string.h> + + unsigned long long HX_strtoull_sec(const char *s, char **end); + char *HX_unit_seconds(char *out, size_t outsize, + unsigned long long seconds, + unsigned int flags); + +``HX_strtoull_sec`` converts a time duration with units, such as ``"15min30s"`` +into an all-seconds value. The recognized unit strings are: ``years``, +``year``, ``y``, ``months``, ``month``, ``days``, ``day``, ``d``, ``hours``, +``hour``, ``h``, ``minutes``, ``minute``, ``min``, ``seconds``, ``second``, +``s`` and the empty string (for seconds).
