This Developer Toolkit is still underdeveloped. A work in progress.

This is a toolkit of programs and scripts used for developing and testing in Unix and Linux environments. It contains several command-line utilities and libraries implemented in C, some shell script packages and other components that have been helpful to me as a developer. It is an on-going project so it will continue to grow and change as I continue to work on it. Most of these things developed from my work in all kinds of Unix and Linux environments.

• src/lib/devtools - library of datagenerating and text generating functions
• src/bin/dg - datagenerator command-line utility
• src/tests/test_funcs.sh - Runs test of test programs
• Makefile - used to build c-compiled binaries, including various utilities, test programs, libraries; runs tests.
• README.md - This file you are reading.

String compare function used for sortlist

int cstring_cmp(const void *a, const void*b);

Returns a sorted string list

char **sortlist(char **strlist);

Returns a random int

int randint(int max_int);

Returns a random alphabetic character

char randalpha(void);

Returns a randomly generated alphabetic string of length len

char *mkalpha(int len);

Returns a randomly generated alphanumeric string of length len

char *mkalphanum(int len);

Returns a randomly generic numeric string of length len

char *mknumeric(int len);

Returns a char** list of tokens of string s and using separator delim. The list itself is terminated by a NULL.

char **split(char *s,char *delim);

Returns the length of string list sl. Only char ** lists terminated by a NULL should be used with this function. Using it with any other type of list is undefined.

int strllen(char **sl);

Returns a c-string created from a string list strlist joined with separator sep.

char *join(char **strlist,char *sep);

Tests if string s is in string list list. Returns non-zero for true, zero for false.

int inlist(char *str,char **list);

Returns a randomly selected string from list if list is a null-terminated string list.

char *randomstring(char **list);

Returns a null-terminated string list of size capacity, populated by variable number of strings less than or equal to capacity.

char **makelist(size_t capacity,...);

Used to insert string new_string into string list list. Returns new list length.

int list_insert(char *new_string,char **list,int pos);

Used to insert a string new_string to the end of a NULL-terminated string list.

int list_append(char *new_string, char **list);
