vim-address-match

Match IPv4 addresses and MAC addresses (colon- and dot-styles)

This plugin enables search matches of the following types:

• Traditional colon-style MAC addresses of the form xx:xx:xx:xx:xx:xx (ignoring case)
• Cisco dot-style MAC addresses of the form xxxx.xxxx.xxxx (ignoring case)
• IPv4 addresses of the form d.d.d.d, with each decimal octet restricted to 0-255
• IPv4 CIDR blocks of the form d.d.d.d/pfxlen, with pfxlen restricted to 0-32
• IPv4 private addresses and CIDR blocks (i.e., within blocks 10/8, 172.16/12, 192.168/16)
• IPv4 special and reserved addresses and CIDR blocks (all lumped together)
• IPv4 public addresses and CIDR blocks

In addition to matching the patterns noted above, the plugin enables the following.

• Conversion of colon-style MACs to dot-style MACs and vice-versa. (Note: when converting, dot-style MACs always are generated in lowercase.)
• Conversion of uppercase colon-style MACs to lowercase MACs and vice-versa.

The plugin defines the following command registrations and key mappings.

• Creates :xxx command registration aliases for the AddressMatch() function. (Set g:address_match_no_commands to disable.)
• Creates <leader>xxx normal mode key mappings for match and convert operations. (Set g:address_match_no_mappings to disable.)
• Creates text objects for all address types using the kana/vim-textobj-user plugin, establishing key mappings for search and selection. (Set g:address_match_no_textobj to disable.)

Command-mode registrations

Unless g:address_match_no_commands is set, the following commands will be registered.

MAC address matching

• :MCM MAC address colon-style match
• :MDM MAC address dot-style match
• :MAM MAC address any-style match

IPv4 address and address-block matching

• :MIP IPv4 address match
• :MBL IPv4 address block match (i.e., CIDR match n.n.n.n/p)
• :MIS IPv4 subnet match (same as MBL above)
• :MPR IPv4 private address/block match (i.e., 10/8, 172.16/12, 192.168/16)
• :MSP IPv4 special address/block match (i.e., multicast, reserved)
• :MPU IPv4 public address/block match (neither private nor special)

Normal-mode mappings using <leader>

Unless g:address_match_no_mappings is set, the following VIM normal-mode mappings will be defined.

MAC address matching and manipulation

• <leader>mcm MAC address colon-style match
• <leader>mdm MAC address dot-style match
• <leader>mam MAC address any-style match
• <leader>dtc MAC address dot- to lower-case colon-style conversion, then match as with mcm
• <leader>dtC MAC address dot- to upper-case colon-style conversion, then match as with mcm
• <leader>ctd MAC address colon- to lower-case dot-style conversion, then match as with mdm
• <leader>ctl MAC address colon-style to lower-case conversion, then match as with mcm
• <leader>ctu MAC address colon-style to upper-case conversion, then match as with mcm

IPv4 address and CIDR matching

• <leader>mip IPv4 address match
• <leader>mbl IPv4 address block match (i.e., CIDR match n.n.n.n/p)
• <leader>mis IPv4 subnet match (same as mbl above)
• <leader>maa IPv4 any address/block match
• <leader>mpr IPv4 private address/block match (i.e., 10/8, 172.16/12, 192.168/16)
• <leader>msp IPv4 special address/block match (i.e., multicast, reserved)
• <leader>mpu IPv4 public address/block match (neither private nor special)

MAC addresses and IPv4 addresses/blocks as text objects

Leveraging the kana/vim-textobj-user plugin, this plugin can treat MAC addresses and IPv4 addresses and address-blocks as textj objects. This provides a set of motion-commands that can be used in conjunction with actions such as delete and yank. It also establishes a set of navigation commands, leveraging the <localleader> character.

If the vim-textobj-user plugin is not installed, or if g.address_match_no_textobj is set, text object functionality will be disabled.

If g.textobj_addressmatch_no_default_key_mappings set to True, the key mappings below will not be established. (In other words :TextobjAddressmatchDefaultKeyMappings will not be executed automatically.)

TextobjAddressmatch selection key mappings

In all of the following cases, the op (yank, delete, etc.) will be executed upon the selected text object. That object will be the one under the cursor or the next one in the buffer. The search will not wrap to the beginning of the buffer. The cursor will be left positioned at the beginning of the text object.

• {op}acm perform op on current/next colon-style MAC
• {op}adm perform op on current/next dot-style MAC
• {op}aam perform op on current/next any-style MAC
• {op}aip perform op on current/next IPv4 address
• {op}abl perform op on current/next IPv4 CIDR block
• {op}ais perform op on current/next IPv4 subnet (same as abl)
• {op}aaa perform op on current/next IPv4 address or block
• {op}apr perform op on current/next IPv4 private address or block
• {op}apu perform op on current/next IPv4 public address or block
• {op}asp perform op on current/next IPv4 special address or block

TextobjAddressmatch movement key mappings

In all of the following cases, the cursor will move to the beginning of the next matching text object. The search will not wrap to the beginning (or in the case of reverse search, end) of the buffer.

• <localleader>cm, <localleader>CM forward, backward to colon-style MAC
• <localleader>dm, <localleader>DM forward, backward to dot-style MAC
• <localleader>am, <localleader>AM forward, backward to any-style MAC
• <localleader>ip, <localleader>IP forward, backward to IPv4 address
• <localleader>bl, <localleader>BL forward, backward to IPv4 CIDR block
• <localleader>is, <localleader>IS forward, backward to IPv4 subnet (same as bl, BL)
• <localleader>aa, <localleader>aa forward, backward to any IPv4 address/block
• <localleader>pr, <localleader>pr forward, backward to private IPv4 address/block
• <localleader>pr, <localleader>pu forward, backward to public IPv4 address/block
• <localleader>sp, <localleader>sp forward, backward to special IPv4 address/block

Matching pattern definitions

The regular expressions used to match MAC addresses and IPv4 addresses and blocks are available in the following global variables.

• g:address_match.dot_mac.pattern - dot-style MAC address
• g:address_match.colon_mac.pattern - colon-style MAC address
• g:address_match.any_mac.pattern - any-style MAC address
• g:address_match.ipv4.pattern - IPv4 address
• g:address_match.any_address.pattern - IPv4 address or address-block (CIDR)
• g:address_match.private.pattern - IPv4 private address (aka, RFC-1918)
• g:address_match.public.pattern - IPv4 public addresses (neither public nor special)
• g:address_match.special.pattern - IPv4 special addresses (multicast, reserved)
• g:address_match.cidr.pattern - IPv4 address block in CIDR notation, n.n.n.n/p
